Many educators have shifted from using the blackboard to using powerpoints and overhead projectors, while some still uses blackboards to teach. In my experience, it is usually harder for me to follow the professor when he/she uses the blackboard, since the professor talks and writes at the same time. Students usually want to get down every bit of information that the professor gives out, whether it's verbal or written. This is why powerpoints are an effective tool in teaching, provided that the professor does not read out the powerpoint. Another solution would be providing audio or video podcast so students can review the materials they might have missed. Videos would also be very helpful in chemistry or other science labs. It can be used to demonstrate lab techniques or how to operate different instruments. I think this would be a lot more effective in preparing students before performing the experiment.
Many employers have stated that they prefer job applicants to have in-depth knowledge of basic chemistry theories and creative thinking than to have the understanding of technology used in labs, which can be obsolete in a few years. But job listings specified that the knowledge of many different technologies used in labs are required. I believe schools should put a bit more focus on practical skills and to be more technology oriented to accommodate the needs of the industry.
