Free Radical Halogenation Lecture & Protein Strux Lecture
I attempted my first in-class recording of a lecture in Organic Chemistry for those who were either absent or those who would like to review the material covered in class since it can go fast in lecture. I realize that some times people wish they could have more time to think over the topic. I've had students ask if they could record the lectures, and I have always agreed. This semester, the university has loaned me an iPad for my Chemistry of Cancer iTunesU course so I thought I would attempt something new and put it to use in Organic Chem as well. Well...it was worth a shot. Now, I'll just have to see if it helps anyone in studying for the exam :)
I do have to say that I have problems viewing it in YouTube...so thank God for Vimeo!
It will be interesting to see if it helps anyone.
UPDATE: I have now added a voiceover to the PowerPoint presentation of chapter 5 (part 1) from Biochem 1 to vimeo as well.
I've always found that recording lectures are very helpful. When I took Organic Chemistry, my professor recorded all of his lectures and posted them on the college website as podcasts almost exactly how this video is. As a visual and auditory learner, watching recordings of the lectures were extremely helpful for me. If I didn't understand a certain part of the lecture, I would just skip to that particular section and watch it over and over until it started making sense to me. I would also go over all of the recorded lectures before a test, and before the final exam, I went all the way back to the recorded lectures from the first few weeks of school. I find it amazing that technology has advanced so much that we can do things like record lectures while drawing out chemical mechanisms, electronically, and be able to replay it from the comfort of our own home. This is a lot different then just the old chalkboard. I definitely think that this will help a majority of students, and hopefully it will even help the students that skip class.
ReplyDeleteIt's wonderful that SEU is incorporating this technology for teachers to use. The Macbook Pro is an excellent piece of equipment and works very well as a teaching tool. Recording lectures is a innovative technique because it allows students to rewind and rewatch portions that are more difficult to understand. I especially like watching mechanisms and chemical syntheses on the smart board because it's very direct and presents everything right there on the screen, which makes it easy to follow. Reviewing graphical differences between myoglobin and hemoglobin, for example, is much easier when one can pause the lecture and take a moment to observe the curves in greater detail. Recording lectures in this way is a great method for helping students (hopefully) boost test scores. It would be an interesting experiment to compare students' grades using this technology versus those of past semesters before these lectures were recorded.
ReplyDeleteThank you for taking the time to make the recording for Biochemistry. It is always frustrating to miss class and rely on someone’s notes. While I do not think recorded lectures are a sufficient replacement lecture for myself, it is greatly preferable to relying on another student’s interpretation. Different students often create their own analogies in their notes to help them better understand certain concepts they struggle with. This causes students notes to vary greatly in their message and composition. While beggars cannot be choosers, it is awesome that this technology allows the student to hear and see almost exactly what happened during the lecture. This allows students to determine for themselves what they believe were the most important parts during lecture and which concepts they should focus on for further study. Hopefully, the university will realize the power of this tool and incorporate videos into their online courses. Currently, the online courses consist mostly of reading the textbook and posting on forum discussions. I believe that recorded video lectures would greatly boost the value of online courses.
ReplyDeleteThrough the marvels of modern technology, study tools once again transcend second hand information. Life has its common occurrences where it will reconvene after a brief word from its sponsors. In short, life happens. Although it is ideal that every student be present for every lecture, this simply is not the case. Upon those absences, excused or not, vital information is missed during the lecture portion of class. In years past, students had to rely on other students to explain information they themselves had just accumulated. It was irrational for a student to grasp the information only a trained professional is qualified to answer. With the use of Apple technology, professors can record lectures and upload them to a server for their students to access. Perhaps the student does not quite understand the material of today's lecture. Instead of leaving them to their own vices, recorded lectures allow for playback until the information is grasped. This technology may also benefit different learning styles of students. Visual learners can replay today's lecture up close to trigger visual preceptors. Auditory learners can listen to lectures repetitively. Kinesthetic learners can copy down lecture notes without fear of missing information by pausing the session. All three learning styles benefit from recorded lectures. By implementing recorded lectures into the classroom I believe test scores will be affected in a positive manor. Student will not only learn to excel on exams, but they will learn vital information in preparation for their professional careers.

ReplyDeleteThank you so much for posting this! I know you probably won't have time to do this for every lecture this semester, but I hope that it will benefit my studying and possibly next year's class. I was able to review concepts so much better when I could listen to Camtasia lectures or watch instructional videos online (like Chad's videos or Khan Academy). Maybe if I listen to this lecture in my REM sleep I will be able to retain more of the details. Many studies have shown how students can retain more information if they listen to lectures while sleeping, but of course the catch is you have to pay attention to the material when it is first presented. Therefore, we students cannot use falling asleep in class as an excuse for deep wave osmosis (wouldn't that be nice) because only this technique only reinforces preexisting connections.

What a great idea! I think this way will really help people, including myself, in learning the material. Since it offers visual and audio, it can help in all types of learning. When I visited a medical school last year the professors did the same thing, even though it was more like a video of them lecturing, but still somewhat of the same concept. It also provides a different way of studying then just having to rely on what you might have said making it a new and interesting way to study the material.
ReplyDeleteI do think this approach is helpful, however, I actually prefer the method of writing everything out on the board and taking notes. I learn the best when things are written out on the board. I do feel that with this age in technology it is smart to move forward, but there is something about the ipad screen that just makes it difficult for me to adapt to. This technique is great for when the material gets challenging and you need to replay the video a few times. It is also helpful for people that need to miss class due to emergencies. I also learn better when handwriting is neat and for some reason the writing on the ipad is so messy and it makes it hard for me to learn. It comes down to the fact that I am OCD and I need to learn to adapt better to technology.
ReplyDeleteVideo lecture is great method to learn better in organic chemistry, like wise also the old method of writing on the board is the best to learn faster. I like watching video online but i learn better in the class.
