Improve student learning outcomes in reproductive system materials using two stay two stray cooperative learning model.

This research is motivated by the teaching and learning process, especially in Biology subjects which require a technique, approach, strategy and learning model that involves students being directly involved in learning based on preliminary studies conducted by the author at one of the SMAs, namely MA Ar-Rasyidiyyah using the technique interview with class. Biology teacher XI. This study aims to analyze the implementation of learning, increase learning outcomes, and student responses to the TwoStayTwoStray learning model. The method in this study used a pre-experimental research design, the sampling technique used a purposive sampling technique using 1 class, namely class XIIPA1 as an experimental class with 24 research subjects. The results showed that the average percentage of teacher activity implementation was 91.3% and student activity reached 92.6% in the application of the TSTS model in the learning process of the reproductive system subject. Student learning outcomes have increased based on the acquisition of a Gain value of 0.67 with a moderate interpretation, and student responses to the TSTS model learning process show a positive response where an average value of 76% is obtained with a good interpretation. percentage in very good category. The increase in student learning outcomes analyzed using SPSS version 21 shows an Asymp. Sig(2-tile) value of 0.000 <0.05, thus the hypothesis can be accepted where there is an increase in student learning outcomes using the TSTS model in Reproductive Systems lessons. Likewise, the percentage of student questionnaire scores on the TSTS model shows a response in the good category. [ABSTRACT FROM AUTHOR]
