Action Research Midterm Progress Report Mayme Walters & Jennifer Olker East High School – 10th grade Regular and Honors Biology Introduction Issue Students have difficulty understanding how to work with data, create or interpret graphs, and use graphing programs such as Microsoft Excel. These skills are valuable for excelling on the standardized tests and continuing on in the sciences (in secondary school and beyond). By incorporating real biological data to match the existing biology curriculum, we hope to supplement the information provided through lectures, laboratory activities, and the textbook. These datasets also provide an additional source of concrete experiences that can provide motivation for learning biology topics [3]. Research Question: Is it possible to incorporate real data and graphing into the existing 10th grade Biology class? Does this improve the students’ ability to graph data or interpret charts? Project Goals 1. Incorporate real data and graphing into curriculum (practicality, application) 2. Improve students’ ability to make graphs 3. Improve students’ abilitiy to interpret data 4. Improve students’ ability to use Excel 5. Improve student attitude towards working with data Methods Investigation: To investigate this question we will add real data and graphing examples and assignments to the existing biology lessons, where possible. Evaluation: For each added data/graph example or assignment, we will evaluate the “success” of the component after the lesson is completed. At the end of each grading period, students’ assignments will be examined for change. Ruberic was developed to evaluate the five project goals, with 12 students selected from 1 class period for assignment evaluation. Conclusions Data sets can be incorporated into the current curriculum with sufficient preparation time, but lessons require large chunks of class time. Additionally, teachers must be prepared to address technical difficulties and provide hand-graphing options. We determined that it is possible to incorporate real data and graphing into curriculum, and these additions are especially beneficial when they supplement unit lessons. Data sets can provide the concrete experience that motivates learning and leads to greater student engagement and understanding. Adding smaller graphing components may be more practical than creating new full lesson plans for graphing.
