Abstract

The two stay two stray cooperative learning model basically emphasizes students to work together in groups, and provides opportunities for groups to share the results and information obtained with other groups, so that the learning process will be student-centered. This study aims to achieve optimum student learning activities through the application of the Two Stay Two Stray (TSTS) model in learning the concepts of alpha, beta and gamma rays, and to describe the student's response to the TSTS cooperative learning that has been implemented. The method used is quantitative with the pre-experimental research model type one shot case study. A total of 26 students taking radiochemistry courses were the subjects of this study. Research data were collected through student activity observation sheets during lectures and a student response questionnaire consisting of 10 statements. The results of observations on student activities show that the aspect of explaining in the lecture material, the aspect of cooperation between colleagues, and the activity of answering questions, respectively, have a value of 86, 85 and 90 percent. In general, students' positive responses to the application of the TSTS model were 95%. From the research results, it can be concluded that the implementation of TSTS is very effective in increasing student learning activities, making students happy in learning, and fostering self-confidence in learning.

Abstract

Learning curriculum in a vocational school combines the adaptive, normative and productive subject group. The adaptive, normative and productive subject groups are expected to be mutually supportive and complementary, in fact the group of subjects did not support each other. The purpose of this study is to develop a learning module for productive subject package (composting techniques) which is integrated by the concept of chemistry as one of the adaptive subjects in vocational school, another purpose of this study is to collect the responses of teachers and students on the module, the module quality assessment by experts, assessment of the portion of chemical concepts that integrated in the module by specialists and module effectivity test. The development of module is using the one of instructional development model in teaching materials development known as ADDIE model (analysis, design, development, implementation, evaluation). The results showed that 92% of teachers responded positively to the module, 85% of students responded positively . While the negative resposes from teacher wes 8% and 15% for student responses. The module quality assessment indicate score 3.36 which the criteria "good" and the expert assessment of chemical concepts are integrated in the module is 70% - 80%. The effectivity of module using student test results indicate the average grades is 92 which criteria "very good". The results suggest that the effectivity of the module is very good for learning.
