My Final WPP for CEP 812 at Michigan State University
You are an awesome teacher. You planned well and executed that dissection
or lab in your class today. Your
students were excited to try it on their own next and thrilled to see the
results of their own work. But wait,
what about Johnny who missed class today?
How is he going to be able to do the lab worksheet without actually
doing the dissection or lab? How do I
get this lesson across to him when I need to move on to the next subject
tomorrow?
The answer is simple - you create a
video cast of the dissection or lab while you are demonstrating to the
class. Johnny can view the video via DVD,
on the computer via web link, or even on his mobile device at his own
convenience! Research has shown that
video in no way replaces hands on activities; however, they are a valuable tool
for the student to use than just the worksheet they missed in class. My own experience has shown that students may
not get the material as well if they had participated in the lab, but much
better than the results if they did not have this extra resource.
Sometimes premade videos are available online, but not always will the video be exactly what the teacher needs to convey. Also, students take the lab more seriously when they see their own teacher perform the lab themselves. This proves that the teacher, in fact, will still do the procedure and that he or she is not showing a video because they don’t want to do the procedure themselves.
TPACK is the Technological
Pedagogical and Content Knowledge, or the ways of representing and formulating
the subject that make it comprehensible to others.
The TP (Technological Pedagogical) knowledge is supported through the actual demonstration of the dissection from the teacher. The teacher usually will demonstrate the dissection to the class of this age group before the class does the dissection on their own. Due to the small size of the object being dissected and the size of the class, it is often difficult for all students to clearly see the teacher’s demonstration. This is where technology helps out. By recording the dissection, the teacher can get clear images; zoom in and out on areas of discussion and voice over the video, thereby ensuring that all parts of the discussion are covered for the class. This video then can be played to all students (even those who may be absent), allowing for a better viewing and understanding of the procedure.
The TC (Technological Content) knowledge makes the dissection demonstration more intellectually accessible through the viewing of the video. The video can show much more detail that what students would be able to see in a live demonstration. The specimen can be seen in more depth by zooming in and out on the subject. A voice over can then be applied, ensuring that all areas of discussion are covered in the video where a live performance might miss a few things since the teacher is concentrating on the dissection, and not the curriculum. Students who are absent on the day of the lab will have a visual experience without actually using a specimen. Students with allergies, visual handicaps or sickness due to sight or smell, personal beliefs will also be able to experience the dissection through this alternate/additional representation.
The PC (Pedagogical Content) knowledge is also supported through the video. Students will be able to see more, and in more detail with the video than from across a table or room. The video will be able to zoom in and out on the subject matter, giving the students a detailed experience rather than viewed from a distance. Students can also replay the video if needed to help grasp the content, or pause the video to allow them to do the step before progressing. Currently, students who are absent on the day of the lab totally miss out on the experience. The video will allow these students to view the dissection in detail, even if they are not able to perform one on their own at a later date. Students having difficulty with hands-on due to smells or upset stomachs will also have an advantage with the detail of the video. Students with beliefs that prevent them from performing a dissection can also utilize the video to cover the material.

The implementation of the video cast
went well for the first try. As with
anything, we learn from our mistakes and success, and we improve our craft over
time.
I was surprised at how large the
original file was for my first video. As
I got more comfortable with Camtasia, I have noted that video quality setting
are available and the size of the file can be drastically reduced in the
future.
An unexpected bump in the road
included the fact that the smart phone I used as a video camera did not allow
for a tri-pod to hold the camera steady.
My film is definitely shaky from this lack of equipment. I also had limited zoom capabilities, so I
intend on purchasing a nicer video camera and tripod in the near future.
The sound quality was not that bad
for not having a remote microphone.
There is some background noise from the operation and movement of the
camera. A remote microphone and tripod
will definitely improve the sound quality.
I am also sure that a better quality camera will also have improved
audio capabilities.
The original project was planned as a dissection, but was
changed to a lab due to current classroom need.
Being absent the day of the lab proposed the same issues if the students
were absent for a dissection, so this seemed like a perfect fit. We have
recorded the lab and placed it on my wife’s web site.
Current practice would have the
student who missed the lab sit down with their scheduled lab partner(s) to
discuss the lab, take notes and complete the worksheet. The student would
miss out on the actual lab and would not be able to see the lab happen, and the
learning from that experience. Of course, this puts both students a
little behind in the class when they are performing these tasks as the class
moves on to other lessons. A video of the lab would allow the absent
student a chance to view the lab as if they were there to see it happen.
Residing on the web, the student can also view the video after class so they do
not miss the current class in session, or distract their lab partner(s) from
the current lesson either. This is a win situation for more than just the
absent student!
I would love to do more of these
projects, but there are a few things I would change in the future. For
one, I would get a regular video camera instead of using my smart phone.
At this time, this was the only equipment available to us. A regular
video camera would have optical zoom instead of only digital zoom which my
phone has. I would also use a tri-pod to hold the camera in place and
keep it steady during filming. I thought the audio was acceptable in my
test, but I might add a microphone to get clearer audio next time.
It is definitely much easier to
perform this function with technical help while you are trying to perform a
lab. Other options are available, but assistance makes it much
easier. The areas of improvement discussed above would also be suggestions
for others who might want to perform this task.
This project was done as a test and
not performed in class as originally planned. There are some benefits to
doing it this way as you don’t have the classroom distractions. Doing the
lab ahead of time allows the presenter to be totally prepared, but it also
requires more supplies if you are still doing the presentation live for the
students. Doing the taping in the classroom allows for questions to be
heard, but also allows for distractions and less prep time to finish the
recording and posting it. I can see myself utilizing both conditions for
future recordings.
Overall, this project was
successful. Absent students were able to
get much more out of the lab than if this video was not available to them. In addition to benefits for the absent
students, students with disabilities will be able to utilize this video as well
as students who wish to review. I highly
recommend making video casts of labs and dissections.
