Acids and Bases StAIR

Rating: 4 stars
Used in Course: Not used in course
Submitted by: Tammie Mirolli (Teacher (K-12)), Jun 20, 2011

Your StAIR is similar to what I am looking to do in my classroom next year.  The "Flipped Classroom"  uses video screenscasts to present lecture notes and practice problems to students.  But these videos are viewed as homework, and then classtime is used for group work, labs, and hands on activities under the guidance of the teacher.  I am excited about trying this and your video is very similar to the videos I have seen from other teachers already using the flipped classroom method.

I tried a unit of video screen casts with my students, but I had just recorded my PowerPoint presentation with voiceover.  Many of my students commented that they would like to have a video of me included with the video.  So I think the video of you helps to engage and connect the students to the material.  Also the students stay focused when they are able to see you.  I know I preferred being able to see you as you worked through the problems.

I like how you broke down the types of acids.  I felt your explanation was very easy to follow, and it should be very clear to students how to identify the different types of acids based on the elements that make up the acid.  I liked your method of explanation so much that I will be using the same explanation with my own students next year.

Modeling how to indentify the types of acids and bases is very important. I think using examples and working through the worksheet is a great way for students to develop the thought process involved in determining whether the substance is a acid or base, and what type of acid it is.  Just giving students the rule would not be as effective as you showing them your thought process when determining acid or base identity.

Technical Remarks:

The one thing that really stood out to me was the placement of your video box.  I felt that it cut off portions of the worksheet and the material you were writing in.  I think if you placed the videon on the bottom right corner and then moved your worksheet up as you worked, would help students to see everything you are doing on the screen.

I agree with Jessica in terms of you leaving the video screen when working on the problems.  Repositioning the camera my make it easyer for you to stay in frame during the whole tutorial.

Finally, on the first quiz,  I tried to fill in the blank on the last question and could not.  I am on a MAC and I don't know if I don't have the proper plug-in or software for me to complete the question.
