The Effectiveness of Physical Education Classes Through Collaborative Learning Methods for the Physical Development of 11th-Grade Students in Vietnam

Introduction. Collaborative Learning (CL) is a group learning method that involves mutual support and assistance among individual students to achieve learning goals. The purpose of this study is to assess the effectiveness of a 14-week Physical Education (PE) class using the CL method in enhancing the physical development of 11th-grade students. Material and Methods. Eighty healthy students were randomly selected and divided into two groups: the experimental group with 40 students applying the CL method in PE classes, and the control group with 40 students studying PE using conventional methods. In this study, five fitness tests were used such as a 30-s sit-up test, a 30-m sprint test, a 4 × 10-m shuttle run test, a standing long jump test, and a 5-min running field test. Results. After 14 weeks of experimentation, independent t-test results indicated a significant difference in the mean values between the experimental and control groups at the threshold of p
