Chemistry is colorful, odiferous, fast or
slow, explosive, fiery, hot or cold, tactile. It is related
in wonderful ways to almost everything that is tangible, and
it happens everywhere! Everyone can have a fun time with chemistry!
There are so many “why’s?” that can be answered
when you know just a little bit of chemistry. That chemistry
has all these wonderful characteristics implies that it would
be an easy sell. But that has not proven to be the case. At
the college level, many students take chemistry courses because
they have to…because it is a “requirement for
their major”. It is often perceived to be an unpleasant
but required obstacle to their future goals. So how does one
get past this, so that the wonders of the subject can be conveyed
to students?
I have found in my own experience that there
are certain prime conditions that are conducive to learning,
regardless of the nature of the subject matter. These prerequisites
are particularly important for subjects like chemistry, where
there may be mental blocks to learning. Interestingly, the
prime learning conditions have nothing to do with chemistry
per se. Chemistry’s bad reputation has much less to
do with the subject matter, and more to do with the environment
in which it is often taught, the mode of its delivery, and
attitude of the deliverer. What one has to accomplish as a
teacher is a “safe learning environment”.
My teaching philosophy is based on the premise
that for a student to learn some chemistry, they need to care
to learn chemistry. Caring does not mean that they will want
to major in it, or even that they will pass the course. It
does mean that they will want to come to class because they
will definitely learn something very fascinating that they
can share with people they know, or use themselves. It also
means that they will come to class because they are assured
that their spirits will be uplifted, and that at some point
during the lecture, they are likely to smile or even laugh.
After all, chemistry can also be very funny. The cultivation
of the attribute of ‘caring to learn’ occurs only
in safe environments. I have found that safety is generated
through:
1. clear articulation of goals and expectations
2. validation of student fears and concerns
3. acknowledgement of the challenges of the subject matter
4. adoption of a non-patronizing attitude
5. the practice of truthfulness
6. a perpetual show of genuine respect
7. maintenance of high standards
8. a smiling and reassuring face
9. enthusiasm on the part of the instructor
10. being mindful of the influence that background cultural
differences has on learning styles
Once the safe environment is created, the students become
comfortable enough to forget themselves and their fears, and
then they start to really hear and see what is going on. This
is followed by a sense of wonderment, and a recognition of
the patterns of chemistry that are so crucial to developing
an understanding of the subject matter. In such an environment,
students freely ask questions, and start to discover some
of the numerous interesting problems that remain to be solved.
The aforementioned factors that I feel contribute to a safe
learning environment are, for the most part, ‘intangibles’.
I have found that it is also important to be well prepared,
and be receptive to newer more student friendly ways of conveying
information, whether it be in the form of web accessible tools,
or increasing the number of ways in which a difficult concept
can be explained. Among other things, I have found the following
to enhance and facilitate the learning experience of students:
1. providing online access to lecture notes, course syllabi,
class announcements etc.
2. giving students access to me via e-mail, and responding
to their questions and concerns promptly
3. breaking the lecture period up so that ample time is provided
for solving chemistry problems in class, with every third
lecture being devoted to problem solving
4. constantly demonstrating the relevance of chemical principles
to real life situations
5. giving importance to student responses on entrance and
exit questionnaires that are provided at the beginning and
end of the semester respectively
6. giving students access to tutorials and self tests
7. mentoring
I consider assessment of student performance
to be a critical aspect of teaching. I insist on excellence.
I believe that it is absolutely essential that the methods
used to assess students are honest and fair, and that they
not change from semester to semester. I apply an absolute
scale, and I do not ‘grade on a curve’. On the
first day of class, students are provided with the scale in
the course syllabus, and this allows them to assess their
performance at any point in the semester, regardless of the
performance of the other students in the class, or other students
who have taken or will take the class.
Through my service as a teacher, particularly
at the undergraduate level, I have had the good fortune of
having numerous rewarding experiences mentoring talented and
culturally diverse students. I encourage those who are interested
to do hands on laboratory research, and the results have been
very fruitful. Most of these students go on to high profile
institutions for graduate (or medical) school. They often
have worked well and conscientiously enough to be co-authors
on peer-reviewed publications, and several of them have won
national awards based upon the work they conducted in the
lab. To date, I have mentored 14 undergraduate students, and
I look forward to continuing these productive collaborations.
Although mastery of the material is an obvious
aim of the courses I teach, I feel that a successful semester
of teaching is one in which I have learned something new about
teaching, and the students have learned what questions to
ask, how to reason analytically, and how to deductively reason
through solving issues and problems, whether or not they pertain
to chemistry. |
