健康體位為主題之PBL 專題式學習課程之行動 研究－以國小四、五、六年級學童為例

Action research of project based learning courses with a theme of healthy body type in Grade 4-6.

個案學校實施PBL(Project- Based Learning， PBL)課程專題式學習方法，對 學童從事健康生活具有相當成效。研究結果顯示，在BMI（Body Mass Index， BMI）值、營養知識具顯著差異；身高、體型、體位、費力運動時間、中等費 力運動時間、走路運動時間、體適能增進、體重、不喝加糖飲料的信心、外食 會吃到「一拳半」煮熟蔬菜的信心、打電腦不超過二小時的信心有明顯進步， 顯見活動介入策略是具成效的。此外，實施PBL課程專題式學習面臨時間不足、 學童的自我認知與家長配合，及是否能持之以恆之問題，都是未來健康體位活 動的重要參考。

Teachers carried out the project based learning courses in the case school. and The techniques are suitable both for kids who are overweight and for those who are underweight. The result shows that there is a statistically significant difference in BMI and nutritional knowledge at students in the case school. There were improvements in students’ height， weight， and figure， and increases in time spent doing moderate and vigorous intensity exercise. Kids spent more time walking and their physical fitness test scores were much higher. When eating out， children knew to avoid sugarless drinks and to try to consume one and a half fists of cooked vegetables. They also learned that they should limit their time playing the computer to two hours. However， the shortage of teaching time， students’ cognition， parents’ cooperation and the endurance of the activity are the suggestions for the further study.
