Winter weather is not fun for skin. Cold weather and low humidity levels result in dry air, which then steals moisture away from the skin every second of every day. Without immediate care, dry skin can lead to cracking and bleeding, and harsh winter wind makes the problem worse. Indoor heat further robs the air of moisture, as do hot showers or baths and harsh cleansers.

Additional moisture helps, but you need to do more to actually counteract these effects and keep skin looking youthful and smooth. To reduce chapping, redness, itching, and keep skin more healthy and comfortable this season, try these tips.
1. Wash in Lukewarm Water

Hot showers and baths always feel good in the winter, but when you can, particularly when just washing your face or hands, choose lukewarm water to avoid stripping as many oils away from the skin.
2. Moisturize Immediately Afterwards

Your skin not only needs more moisture, but moisture right after you wash. Applying moisture to damp skin helps seal that dampness into the skin. Keep a bottle near the bathtub, shower stall, and at every sink and use liberally every time you wash.
3. Choose Moisturizer Carefully

Some over-the-counter moisturizers have petroleum-based ingredients that can actually further dry your skin in the winter months. Be sure to choose a smart formula that has natural, nourishing ingredients. Go for an oil-based rather than a water-based solution, as it’s more likely to help your skin retain moisture in the winter. Try Indie Lee’s natural moisturizing oils, as they’re made with natural, hydrating ingredients like lavender, chamomile, jojoba, and more, which help soothe dry, itchy skin.
4. Protect

Get used to wearing gloves and scarves to protect skin from cold winds, rain, and snow. Also, don’t forget the sunscreen. Winter sun can be just as damaging as summer sun, so apply a safe option like zinc oxide or titanium dioxide to any exposed areas.
5. Humidify

Heating systems dry out the air, so consider installing a humidifier in your home, particularly in your bedroom, to put moisture back into the air and help prevent your skin from drying out.
6. Drink

We tend to drink less water in the winter because we turn to hot drinks like cocoa and tea, but don’t forget that your skin needs hydration from the inside, out. A little warm water with lemon can be very refreshing and hydrating at the same time.
7. Overnight Moisturize

Dryer areas like hands, feet, elbows, and knees have thin skin and tend to lose moisture faster than other areas on the body. Consider slathering on a deep moisturizing balm Skin Food by Weleda at night, then wear cotton gloves and socks to seal in the moisture until morning.
8. Exfoliate

We often forget to help the skin slough off dead cells in the winter, particularly on our hands. Yet moisture can’t get in if the dead cells are too plentiful. Find an exfoliating mask and use it on your face and your hands, as well as gently on your lips, then follow immediately with moisture to truly see a smoother difference. Exfoliating body washes are also helpful in the winter months.
9. Avoid Toxins, Specifically Allergens and Irritants

Particularly if you have eczema, dermatitis, or psoriasis, you have to avoid allergens and irritants that may trigger a flare up. Winter skin is more fragile, so avoid irritating fabrics (like wool) and chemical-laden detergents, and use mild cleansers and moisturizers designed for sensitive skin. In addition, glutathione is considered the “master anti-oxidant” and helps your body detox.
10. Hydrate From the Inside Out

Eating foods high in water content can help hydrate your skin from the inside out. Try watermelon, cantaloupe, apples, oranges, kiwi, and watery veggies like celery, tomatoes, cucumbers, zucchini, and carrots. Make sure you’re getting enough vitamin C and zinc to support the healthy production of collagen and elastin. Also consider Be Well’s omega-3 supplement, or consume more fatty fish and flaxseed to give your skin the building blocks it needs to appear supple and smooth.
11. Change Your Cleanser

Cleansers can be extremely drying to the skin. If you’re used to using options that contain glycolic or salicylic acid, rotate with a more hydrating version that contains moisturizing ingredients. Try like Suki Naturals Moisture-Rich Cleansing Lotion, or for really dry skin, try a cleansing balm like Ren No. 1 Purity Cleansing Balm. After cleansing, don’t leave the skin naked for more than 30 seconds, as this can dehydrate it, leading to increased dryness. Apply a hydrating toner and moisturizer to seal in moisture.
12. Use DIY Masks

Homemade hydrating masks can provide needed moisture in the winter months. Use natural moisturizing ingredients like honey, avocado, yogurt, olive and jojoba oils, almond oil, bananas, and aloe. Mix what you like together to create a cream or paste, and leave on skin for 10-30 minutes for lasting hydration.

Faculty Sections / Evaluation of mobile communication from 1G to 7G...
« on: December 18, 2017, 02:49:51 PM »
The cellular wireless Generation (G) generally refers to a change in the nature of the system, speed, technology and frequency. Each generation have some standards, capacities, techniques and new features which differentiate it from the previous one.

First Generation (1G) :The 1st commercial automated cellular network was launched by NTT in Japan in 1979, followed by the launch of Nordic Mobile Telephone (NMT) system in Denmark, Finland, Norway and Sweden, in 1981.

    Year – 1970 - 1980s
    Standard - AMPS (Advanced Mobile Phone System).
    Services – Only Voice
    Technology – Analog
    Speed - 1kbps to 2.4 kbps
    Multiplexing – FDMA
    Switching – circuit switching
    Core Network – PSTN only
    Frequency – 800- 900 MHz
    RF Bandwidth - 30 kHz. The band can accommodate 832 duplex channels, among which 21 are reserved for call setup, and the rest for voice communication
    Network Components of 1(G)

Poor voice links & no security at all since voice calls were played back in radio towers.

 

 
Second Generation (2G):-

GSM technology was the first one to facilitate digital voice & data and international roaming and allowing customer to roam from place to another. GSM maintains end-to-end security by retaining the confidentiality of calls using Signalling and Data Confidentiality and Mobile station Authentication.

    Year – 1980 -1990
    Technology – Digital
    Speed – 14kbps to 64Kbps
    Frequency Band – 850 - 1900 MHZ (GSM) and 825 – 849 MHz (CDMA)
    Bandwidth/Channel - GSM divides each 200 kHz channel into eight 25 kHz time-slots. CDMA channel is nominally 1.23 MHzwide
    Multiplexing /Access Technology – TDMA & CDMA.
    Switching – Circuit switching
    Standard – GSM (Global System for Mobile Communication), IS-95(CDMA) - used in the Americas and parts of Asia), JDC (Japanese Digital Cellular) (TDMA-based), used in Japan, iDEN (TDMA-based), proprietary network used by Nextel in the United States.

Network Components of 2(G)Services –  Digital Voice, SMS,  International Roaming , Conferencing, Call Waiting, Call Hold, Call Forwarding, Call Barring, Caller Number Identification,  Closed User Groups (CUGs) , USSD Services, Authentication , billing based on the services provided to their customers e.g. charges based on local calls, long distance calls,  discounted calls, real time billing.

Temporary identification numbers are assigned to the subscriber’s number to maintain the privacy of the user. The privacy of the communication is maintained by applying encryption algorithms and frequency hopping that can be enabled using digital systems and signalling
2.5 Generation: Introduction of packet network to provide high speed data transfer & internet.

    Year – 2000- 2003
    Standards - General Packet Radio Service (GPRS) & EDGE (Enhanced Data rates in GSM)
    Frequency: 850 -1900 MHz
    Speed – 115kpbs (GPRS)/384kbps(EDGE)
    Switching – packet switching for data transfer
    Multiplexing – Gaussian minimum shift keying-GMSK(GPRS) & EDGE (8-PSK)
    Services – push to talk, multimedia, web based info entertainment, support WAP, MMS, SMS mobile games, and search and directory, email access, video conferencing. Network Components of 2.5(G)

GPRS provides packet switching protocols, short setup time for ISP connections and the possibility to charge the subscriber according to the amount of data sent rather than connection time. GPRS supports flexible data transmission rates and provides continuous connection with the network.

GPRS is a packet-switched service that takes advantage of available GSM time slots for data communications , supports both X.25 and TCP/IP packet protocols, with quality of service (QoS) mechanisms and is considered most useful for bursty data applications such as mobile Internet browsing, e-mail, and various push technologies

EDGE provides nearly three times faster speeds than the outdated GPRS system. To support higher data rate EDGE adopts higher modulation schemes such as 8-PSK.

EDGE can retransmit a packet with more robust coding scheme. In EDGE re-segmentation is possible while in GPRS re-segmentation is not possible. In EDGE packets are addressed up to 2048 and window size to 1024 while GPRS packets were numbered from 1 to 128 and addressing window size was 64.
Third Generation (3G)

The goal of 3G systems was to offer increased data rates. International Telecommunication Union (ITU) has defined the demand for 3G in the International Mobile Telecommunication (IMT)-2000 standards to facilitate growth, greater voice and data capacity, support diverse applications, and high data transmission at low-cost. The data are sent through the technology called Packet Switching .Voice calls are interpreted through Circuit Switching.

    Year - 2000
    Standards -
        UMTS (WCDMA)– Based on GSM (Global Systems for Mobile) 2G system infrastructure,standardized by 3GPP.
        CDMA 2000 – Based on CDMA (IS-95 ) 2G standard, standardized by 3GPP2.
        TD-SCDMA radio interface was commercialized in 2009 and is only offered in China
    Speed : 384KBPS to 2MBPS
    Frequency : about 8 to 2.5GHz
    Bandwidth – 5 to 20 MHz
    Multiplexing/Access technologies
    Radio interface is called WCDMA (Wideband Code Division Multiple Access)
    HSPA is an upgrades to W-CDMA offers speeds of 14.4 Mbit/s down and 5.76 Mbit/s up.
    HSPA+ can provide theoretical peak data rates up to 168 Mbit/s in the downlink and 22 Mbit/s in the uplink, using air interface improvements & multi-carrier HSPA and MIMO.
    Cdma2000 1X: It can support both voice and data services. The max. Data rate can reach 153 kbps, belonging to 3G mobile communications.

Localized services for accessing traffic and weather updates, Mobile office services, like virtual banking. Greater security features than 2G like Network Access & Domain Security, User Domain and Application Security.

Fourth Generation (4G)

Initiation year-2010.4G - In 2008, ITU-R specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G systems.

The fourth Generation mobile system is all IP based network system. The main goal of 4G technology is to provide high speed, high quality, high capacity, security and low cost services for voice and data services, multimedia and internet over IP.

To use 4G mobile network, multimode user terminals should be able to select the target wireless system. To provide wireless services anytime and anywhere, terminal mobility is a key factor in 4G.


4G introduced new physical radio interface known as Evolved UMTS Terrestrial Radio Access (E-UTRA) and new packet –switching based core network called as Evolved Packet Core (EPC).  IP-based network architecture, allows for seamless handovers for voice and data to GSM, UMTS or CDMA2000 technology.

    Standards - Long-Term Evolution Time-Division Duplex (LTE-TDD and LTE-FDD) Mobile WiMAX standard (802.16m standardized by the IEEE

4G implementation variants :

The LTE standard supports only Packet Switching & is all IP Network. Voice calls in GSM, UMTS and CDMA2000 are circuit swiyched, so with the adoption of LTE, carriers will have to re-engineer their voice call network.  However since it requires lot of infrastructure changes, three different approaches are

Voice over LTE (VoLTE) : VoLTE is based on the IP Multimedia Subsystem (IMS) network i.e. voice service (control and media planes) being delivered as data flows within the LTE data bearer. VoLTE has up to three times more voice and data capacity than 3G UMTS. Furthermore, it frees up bandwidth because VoLTE’s packets headers are smaller than those of unoptimized VoIP/LTE.

Circuit-switched fallback (CSFB) : In this approach, LTE just provides data services, and when a voice call is to be initiated or received, it will fall back to the circuit-switched domain. When using this solution, operators just need to upgrade the MSC instead of deploying the IMS, and therefore, can provide services quickly. However, the disadvantage is longer call setup delay.

Simultaneous voice and LTE (SVLTE) : In this approach, the handset works simultaneously in the LTE and circuit switched modes, with the LTE mode providing data services and the circuit switched mode providing the voice service. This is a solution solely based on the handset, which does not have special requirements on the network and does not require the deployment of IMS either. The disadvantage of this solution is that the phone can become expensive with high power consumption.

One additional approach which is not initiated by operators is the usage of over-the-top content (OTT) services, using applications like Skype and Google Talk to provide LTE voice services


Fifth Generation (5G)

Initiation year-2015

It will make Unified global standard. The Physical and Data Link layer defines the 5G wireless technology indicating it as an Open Wireless Architecture(OWA).The 5G technology also maintain virtual multi-wireless network.

To perform this the Network layer is sub-divided into two layers; upper network layer for mobile terminal and lower network layer for interface. Here all the routing will be based on IP addresses which would be different in each IP network worldwide.

In 5G technology the higher bit rate loss is overcome by using Open Transport Protocol (OTP).The OTP is supported by Transport and Session layer. The application layer is for quality of service management over various types of networks. 5G brings forward a real wireless world-Wireless World Wide Web (WWWW)

    Speed - 1 to 10 Gbps.

    Possible, natural disaster including tsunami, earthquake etc. can be detected faster.Architecture

Sixth Generation (6G)

6G is proposed to integrate 5G with satellite networks for global coverage.

It is considered to be a cheap and Fast Internet Technology to provide unbelievably high data rates or very fast Internet speed access on air through wireless and mobile devices possibly up to 11 Gbps, while travelling or in a remote location.

The satellite communication network may consist of telecommunication satellite networks, earth imaging satellite networks and navigation satellite networks. The goal of 6G is to integrate these kinds of satellite networks to provide network position identifier, multimedia and internet connectivity, and weather information services to the mobile users.

Specially designed Nano Antennas will be implemented at different geographical locations or positions along roadsides, villages, malls, airports, hospitals etc to broadcast such high speed electromagnetic signals.

The globe will be decorated by fly sensors with the help of 6G technology. These fly sensors will provide information to their remote observer stations; further these stations will check any activity upon a special area such as the activity of terrorists, intruders etc.

The point to point wireless communication networks that transmit super- fast broadband signals through the air will be assisted by high speed optical fibers lines to broadcast much secured information from transmitters to destinations.

Features/Advantages of 6G Technology:

    Ultra fast access of Internet.
    Data rates will be up to 10-11 Gbps.
    Home automation and other related applications.
    Smart Homes, Cities and Villages.
    May be used in the production of Energy from galactic world.
    Space technology, Defense applications will be modified with 6G networks.
    Home based ATM systems.
    Satellite to Satellite Communication for the development of mankind.
    Natural Calamities will be controlled with 6G networks.
    Sea to Space Communication.
    Mind to Mind Communication may be possible
    Standards :- The Global Position System(GPS) by USA, the Galileo by Europe, the COMPASS by China and the GLONASS by Russia. If 6G integrates with 5G with these satellite networks, it would have four different standards. So handoff and roaming will be can be a big issue in 6G

7G deals with space roaming.

The 7G of mobile wireless networks which aims to acquire space roaming. The world is trying to become completely wireless, demanding uninterrupted access to information anytime and anywhere with better quality, high speed, increased bandwidth and reduction in cost.
Conclusion

The world is trying to become completely wireless, demanding uninterrupted access to information anytime and anywhere with better quality, high speed, increased bandwidth and reduction in cost. After 4G the next generation 5G aims a real wireless world with no limitations while 6G integrates 5G with satellite networks. Due to variable technologies and standards, with 6G handoff/roaming will be an issue. This drives the 7G of mobile wireless networks which aims to acquire space roaming.

Success is a subjective notion, if there ever was one. But for simplicity's sake, let's assume the higher you are on Maslow's hierarchy of needs, the better you're doing. In case you don't remember the levels from Psych 101, essentially, people can't be their best possible selves (self-actualization) until lower-level needs are met first. In other words, you can't be an ideal version of yourself if you don't have enough food and money to pay the bills, or enough love and esteem to feel good about your value as a human being. So, what can you do to move yourself up the pyramid?

Check out the findings from several studies, which shine a light on what it takes to achieve more in life.

Increase your confidence by taking action.

Katty Kay and Claire Shipman, authors of The Confidence Code, wrote a stellar article for The Atlantic on this subject. Highlighting scads of studies that have found that a wide confidence gap exists between the sexes, they point out that success is just as dependent on confidence as it is on competence. Their conclusion? Low confidence results in inaction. "[T]aking action bolsters one's belief in one's ability to succeed," they write. "So confidence accumulates--through hard work, through success, and even through failure."

Broaden your definition of authenticity.

Authenticity is a much sought-after leadership trait, with the prevailing idea being that the best leaders are those who self-disclose, are true to themselves, and who make decisions based on their values. Yet in a recent Harvard Business Review article titled "The Authenticity Paradox," Insead professor Herminia Ibarra discusses interesting research on the subject and tells the cautionary tale of a newly promoted general manager who admitted to subordinates that she felt scared in her expanded role, asking them to help her succeed. "Her candor backfired," Ibarra writes. "She lost credibility with people who wanted and needed a confident leader to take charge." So know this: Play-acting to emulate the qualities of successful leaders doesn't make you a fake. It merely means you're a work in progress.

Improve your social skills.

According to research conducted by University of California Santa Barbara economist Catherine Weinberger, the most successful business people excel in both cognitive ability and social skills, something that hasn't always been true. She crunched data linking adolescent skills in 1972 and 1992 with adult outcomes, and found that in 1980, having both skills didn't correlate with better success, whereas today the combination does. "The people who are both smart and socially adept earn more in today's work force than similarly endowed workers in 1980," she says.

Train yourself to delay gratification.

The classic Marshmallow Experiment of 1972 involved placing a marshmallow in front of a young child, with the promise of a second marshmallow if he or she could refrain from eating the squishy blob while a researcher stepped out of the room for 15 minutes. Follow-up studies over the next 40 years found that the children who were able to resist the temptation to eat the marshmallow grew up to be people with better social skills, higher test scores, and lower incidence of substance abuse. They also turned out to be less obese and better able to deal with stress. But how to improve your ability to delay things like eating junk food when healthy alternatives aren't available, or to remain on the treadmill when you'd rather just stop?

Writer James Clear suggests starting small, choosing one thing to improve incrementally every day, and committing to not pushing off things that take less than two minutes to do, such as washing the dishes after a meal or eating a piece of fruit to work toward the goal of eating healthier. Committing to doing something every single day works too. "Top performers in every field--athletes, musicians, CEOs, artists--they are all more consistent than their peers," he writes. "They show up and deliver day after day while everyone else gets bogged down with the urgencies of daily life and fights a constant battle between procrastination and motivation."

Demonstrate passion and perseverance for long-term goals.

Psychologist Angela Duckworth has spent years studying kids and adults, and found that one characteristic is a significant predictor of success: grit. "Grit is having stamina. Grit is sticking with your future, day in, day out, not just for the week, not just for the month, but for years, and working really hard to make that future a reality," she said in a TED talk on the subject. "Grit is living life like it's a marathon, not a sprint."

Embrace a "growth mindset."

According to research conducted by Stanford psychologist Carol Dweck, how people view their personality affects their capacity for happiness and success. Those with a "fixed mindset" believe things like character, intelligence, and creativity are unchangeable, and avoiding failure is a way of proving skill and smarts. People with a "growth mindset," however, see failure as a way to grow and therefore embrace challenges, persevere against setbacks, learn from criticism, and reach higher levels of achievement. "Do people with this mindset believe that anyone can be anything, that anyone with proper motivation or education can become Einstein or Beethoven? No, but they believe that a person's true potential is unknown (and unknowable); that it's impossible to foresee what can be accomplished with years of passion, toil, and training," she writes.

Invest in your relationships.

After following the lives of 268 Harvard undergraduate males from the classes of 1938 to 1940 for decades, psychiatrist George Vaillant concluded something you probably already know: Love is the key to happiness. Even if a man succeeded in work, amassed piles of money, and experienced good health, without loving relationships he wouldn't be happy, Vaillant found. The longitudinal study showed happiness depends on two things: "One is love," he wrote. "The other is finding a way of coping with life that does not push love away."

Faculty Sections / How to Get PhD Funding
« on: December 18, 2017, 02:34:34 PM »
Professor Daniel Drezner of Tufts University once quipped: “Should you get a PhD? Only if you are crazy or crazy about your subject.” If you fit one of those two categories, you’ll no doubt be keen to find out how to finance your mad endeavor. Here’s a quick guide to getting PhD funding…
How much does a PhD cost? Costs of a PhD

In the first place, how much does a PhD cost? Here, the answer varies considerably by country. In the UK, being a self-funded PhD student can be an expensive undertaking, with an annual tuition bill of approximately £3,000 to £6,000 (about US$4,300-8,700) for domestic students and up to £18,000 ($26,000) for international students for the first three years.

In the US, the price tag for a PhD is even higher, ranging from US$28,000 to US$40,000 per year. In Germany, on the other hand, PhD students face no tuition fees at all, aside from a nominal semester contribution of €150 (~US$162) and €200 (US$217).

Before some of these high figures deter you, be reassured that there are many PhD funding opportunities available; few PhD students are self-funded.

PhD funding from national research councils

In the UK, PhD funding is provided via seven research councils, each covering a specific academic sector. Across Europe, such funding is offered by the European Research Council. Both the US and Canada have the equivalent in their National Research Councils, which give financial support to students either individually, via scholarships, or for funded research projects, via a research group or department.

PhD funding from universities PhD scholarships

Most universities provide substantial scholarships, studentships and other PhD funding opportunities. These schemes typically cover the cost for a good proportion of the annual tuition fees, if not more. Universities often also provide some funding for doctoral students to cover the costs of field trips and conference attendance.

A further means to fund a PhD is by obtaining a PhD position, sometimes also called PhD studentships or assistantships. These are essentially jobs tied to the PhD program, involving work in teaching, research or both. This is an ideal way to support your research, while being involved in a larger, often team-based, funded research project and gaining work experience.

Living costs and opportunity costs

Other costs to be considered when calculating PhD funding are living costs and opportunity costs. Living expenses will of course vary significantly by country and city. Studying in Paris (France) or Oslo (Norway) will likely incur a substantially higher annual cost than completing a PhD in Bangkok (Thailand), for example.

In addition, opportunity costs can be high. Unlike a master’s degree, which usually takes just one or two years full-time, a PhD demands a markedly higher time investment – most programs require an absolute minimum of three years, and some require five to six, depending on the country.

During this time, full-time employment is possible only if it is in relation to the PhD program itself. Some may opt to continue working and attempt to complete a PhD part-time – but this has proven to be exceptionally challenging; some studies suggest that drop-out rates for part-time PhDs are as high as 66%.

Career prospects with a PhD PhD graduates

But while this might all sound daunting, there are considerable benefits and advantages to getting a PhD. In other words: the prospects for careers with a PhD are good. While entry-level salaries may not be considerably higher compared to those for master’s graduates, those with a PhD do have better long-term prospects for faster career- and pay-scale advancements. And a growing number of PhD students consider a post-doc life outside of academia.

There has been a clear trend in non-academic employers (such as consultancies, think tanks, media and others) increasingly valuing not only the specialist knowledge of PhD graduates but also their maturity and soft skills. Attributes valued by PhD employers across a wide range of industries include diligence, research abilities, focus, discipline, presentation skills and the demonstrated ability to work under pressure and to a deadline.

For all those aspiring doctoral students who aim to have a quick return on their investment, a word of caution: the benefits of a PhD are not to be had in the fast lane. The value of a PhD qualification is to be found in the long-term benefits it brings, financially, professionally and intellectually. It is a labor of love, and, as we know there is always some madness in love, but for those with realistic expectations and the discipline and tenacity to complete this highest of academic degrees, it is a tremendously rewarding experience, in more ways than one.

Teaching & Research Forum / 10 tips for a good teacher
« on: March 28, 2016, 11:53:51 AM »
In 1998, professor Leblanc was awarded the Seymous Schulich Award for Teaching Excellence. His top ten requirements for good teaching was originally published in The Teaching Professor, Vol. 12, # 6, 1998.

 

1. GOOD TEACHING is as much about passion as it is about reason. It’s about not only motivating students to learn, but teaching them how to learn, and doing so in a manner that is relevant, meaningful, and memorable. It’s about caring for your craft, having a passion for it, and conveying that passion to everyone, most importantly to your students.
2. GOOD TEACHING is about substance and training students as consumers of knowledge. It’s about doing your best to keep on top of your field, reading sources, inside and outside of your areas of expertise, and being at the leading edge as often as possible. But knowledge is not confined to scholarly journals. Good teaching is also about bridging the gap between theory and practice. It’s about leaving the ivory tower and immersing oneself in the field, talking to, consulting with, and assisting practitioners, and liaising with their communities.
3. GOOD TEACHING is about listening, questioning, being responsive, and remembering that each student and class is different. It’s about eliciting responses and developing the oral communication skills of the quiet students. It’s about pushing students to excel; at the same time, it’s about being human, respecting others, and being professional at all times.
4. GOOD TEACHING is about not always having a fixed agenda and being rigid, but being flexible, fluid, experimenting, and having the confidence to react and adjust to changing circumstances. It’s about getting only 10 percent of what you wanted to do in a class done and still feeling good. It’s about deviating from the course syllabus or lecture schedule easily when there is more and better learning elsewhere. Good teaching is about the creative balance between being an authoritarian dictator on the one hand and a pushover on the other. Good teachers migrate between these poles at all times, depending on the circumstances. They know where they need to be and when.
5. GOOD TEACHING is also about style. Should good teaching be entertaining? You bet! Does this mean that it lacks in substance? Not a chance! Effective teaching is not about being locked with both hands glued to a podium or having your eyes fixated on a slide projector while you drone on. Good teachers work the room and every student in it. They realize that they are conductors and the class is their orchestra. All students play different instruments and at varying proficiencies. A teacher’s job is to develop skills and make these instruments come to life as a coherent whole to make music.
6. GOOD TEACHING is about humor. This is very important. It’s about being self-deprecating and not taking yourself too seriously. It’s often about making innocuous jokes, mostly at your own expense, so that the ice breaks and students learn in a more relaxed atmosphere where you, like them, are human with your own share of faults and shortcomings.
7. GOOD TEACHING is about caring, nurturing, and developing minds and talents. It’s about devoting time, often invisible, to every student. It’s also about the thankless hours of grading, designing or redesigning courses, and preparing materials to further enhance instruction.
8. GOOD TEACHING is supported by strong and visionary leadership, and very tangible instructional support resources, personnel, and funds. Good teaching is continually reinforced by an overarching vision that transcends the entire organization from full professors to part-time instructors and is reflected in what is said, but more importantly by what is done.
9. GOOD TEACHING is about mentoring between senior and junior faculty, teamwork, and being recognized and promoted by one’s peers. Effective teaching should also be rewarded, and poor teaching needs to be remediated through training and development programs.
10. AT THE END OF THE DAY, good teaching is about having fun, experiencing pleasure and intrinsic rewards…like locking eyes with a student in the back row and seeing the synapses and neurons connecting, thoughts being formed, the person becoming better, and a smile cracking across a face as learning all of a sudden happens. It’s about the former student who says your course changed her life. It’s about another telling you that your course was the best one he’s ever taken. Good teachers practice their craft not for the money or because they have to, but because they truly enjoy it and because they want to. Good teachers couldn’t imagine doing anything else.
