Description of Lesson
My lesson plan was designed and implemented as it was intended. I wanted to use technology to supplement my instruction in teaching exponents. Students were given the opportunity to construct their understanding of positive and negative exponents with in-class group assignments. They also were also given practice problems to complete on their own. The next portion of the lesson included using CTB/McGraw-Hill’s Acuity Assessment Program as an instructional resource. I used it to assign additional work as well as to assess student understanding. With this program, students were given a quick tutorial, followed by guided practice, and finally assessed with a six-problem test. Results were sent directly to my teacher account.
Implementation
This lesson was done with both of my remedial math classes as well as all three pre-algebra classes. The first part of the lesson, students were not used to having to construct their own theories/understanding in math. They wanted to be told the answers and how to complete the assignment. I would say that the remedial students were more needy than the Gen-Ed math class, but that is typical of these classes. Once students realized the rules for each section, they were easily able to complete the practice problems.
The second section of this lesson, students were to log onto Acuity and complete both standard based instructional resource. Students did not take their time on the review section, but ultimately scored very well on both standards. Those that did not, I was able to pull aside to work one-on-one with during that class. Then I reassigned those students a test to re-take for partial credit. In most cases, students were able to see their mistakes and complete the second assessment with 100% proficiency.
Reflection
I approached this lesson differently this year than I have in the past years. Normally I teach these lessons from the board while students take notes. Then they practice problems in class as well as at home. Once a section is completed, students would have a paper and pencil quiz. For this lesson I took a constructivism approach to learning by having students work with their peers to construct their own understanding of these exponential concepts. Students were able to use their previous understanding of repeated multiplication and patterns to develop and use the properties of integer exponents.
I also replaced the paper and pencil quiz with an interactive web-based instructional resource. Acuity takes students through a review process as well as a guided practice, and a final assessment. If students at that point had questions, I would work one-on-one with them while others were working on their computers. This extra time allowed for me to differentiate instruction for different learners.
Once students completed their review and guided practice, they were then given an assessment. The results were sent directly to my Acuity Homepage. From there I could review instructional resource results as well as test results. A picture of that can be seen below. After reviewing the results, I worked one-on-one with a student or in small groups. I also allowed students the opportunity to retake the test. Below is an image of the results.
These standards could have been taught using the same approaches that I have used in the past, but the technology not only supplemented my instruction, it also allowed me the time to work one-on-one with students. I believe this benefited student learning as well as my own classroom management. Students were already very comfortable with the online testing aspect because of quarterly Acuity tests. However, they had never completed any additional instructional resources. I was very pleased with their ability to get right to work and successfully complete each lesson. I will continue to use both the technology and the constructivism approach in the future.
