Physical education teachers use a video camera to help students better understand their performance. For the most part, teachers traditionally direct viewing of videos. Remote controls are used to stop and start videos and students are encouraged to discuss their performance. The teacher serves as a guide by simply asking questions. The article reports that teacher comments made more sense after students saw themselves on the videotape.
Students use portable heart monitors to determine their heart rates.
These rates can later be tracked on a spreadsheet to detect if cardiovascular improvements have been made. Electronic diaries include personal evaluations of activities and progress, and a perceived level of exertion scale is used, and comparisons made, by viewing both the diary and the spreadsheet. For example, students view the growth and development of an embryo or a working heart on screen while listening to facts as they move through the process. Nutrition and healthy eating units incorporate software that allows students to modify traditional recipes, track nutrients, vitamins and minerals. Many of these applications collate data for the entire class so teachers can print reports that compare groups.
