Development of the Mathematics Learning Activities Packages in the Topic of Probability Using the Cooperative Learning Theory for 11th Grade Students

Abstract

The research aimed to 1) develop the mathematics learning activities packages in the topic of probability using cooperative learning theory to achieve the 75/75 efficiency, and 2) compare the results of the learning achievement of the 11th grade students before and after they were taught using the mathematics learning activities packages in the topic of probability using cooperative learning theory. The samples used in the research were 42 students studying in the 11th grade in the 2nd semester of the academic year 2017 at Satree Siriket School, Muang, Srisaket who obtained by cluster random sampling. The research instruments consisted of 1) five packages of the mathematics learning activities on the topic of probability using cooperative learning theory and 2) the 30-items learning achievement test in the topic of probability, with 4 choices per each question. The test had a difficulty value which ranging from 0.20 to 0.80, a discrimination value which ranging from 0.20 to 0.96, and a reliability equal to 0.91. The statistics used to analyze data were mean, standard deviation, and dependent sample t-test. The research findings were as follows; 1) The efficiency of the mathematics learning activities packages using the cooperative learning theory for the 11th grade students had the efficiency after the trial equivalent to 78.86/76.75. This showed that the efficiency of the proposed learning packages had met the standard criteria. 2) The results of the learning achievement of the 11th grade students before and after used the mathematics learning activities packages in the topic of probability using the cooperative learning theory revealed that the test scores that the students had after the trial were higher than the test scores before trial with the statistical significance at the level of .05.
