The ultimate goal of teaching is learning. Since learning strategies differ from group to group, from individual to individual, the art of teaching lies in recognizing the specifics of a group of learners and in choosing the right approach and the right set of tools to make learning process effective. I believe this is the universal guideline that an instructor should follow, especially when choosing which technologies are appropriate in which context.

Let me draw a couple of examples from my experience. The students I taught up to this moment may be roughly divided into two categories: the engineering type and the humanitarian type. The first group naturally responded more enthusiastically to classroom technology than the second one. The reason behind it is the difference in the level of computer literacy. Taking into account this issue, one can try to determine the level of technology and the set of teaching techniques appropriate for each of these classes. For instance, students in Math110 would definitely benefit from computer-based techniques and examples of engineering applications, while some Math22 students would not feel comfortable in computer intensive environment and might prefer pictures and some real life analogies instead. This rough division can be refined further and the same analysis can be made within each of the smaller groups. In the scope of this Portfolio I tried to showcase the technologies I exploited in my teaching and to discuss their strengths and weaknesses in light of the aforementioned difficulties.

Of course it is hardly possible to satisfy everyone, but in my opinion there are technologies one can use without much fear of being misunderstood. There are communicating tools I already mentioned in my philosophy statement. E-mail correspondence, online quizzes and various web tools already made their way into today's education. So why not take advantage of them? There are always things that don't work, like the email system within Angel: students are very reluctant in changing their email account, so if an instructor chooses to use Angel mail, he/she should always make sure to forward a copy of the message to students' PSU accounts. There are also software, system malfunctions, which can make students feel angry or disappointed. However, if you have the confidence and are flexible enough to listen to suggestions, you can always find an optimal strategy and make best use of the available technology, to enrich the communication between class participants. The other thing I realized is that no matter what class I teach, making solution sets to homework assignments and quizzes helps students a lot in preparation to exams, so it became the tradition in my classes. Only recently I realized that there is a way to couple effectiveness with efficiency by making electronic reusable versions of the solutions.

An underestimated truth about education is that knowledge can by no means be conveyed without students' good will. If you come to think about it, good teacher, like a good chef, should always prepare a variety of sauces for the dish he/she is serving to make it most appealing, while the task of tasting and judging the dish is always left to the guest. Technology is just another way to help make the outcome enjoyable to both sides, and I hope my students will retain the taste for learning, questioning and discovering long after my classes.
