National Education Act of B.E. 2542 (1999) stated that Education shall be based on the principle that all learners are capable of learning and self – development, and are regarded as being most important. The teaching – learning process shall aim at enabling the learners to develop themselves at their own pace and to the best of the best of their potentiality. Therefore, education management must be focus on the learners to develop the knowledge and the pursuit of self-knowledge and taking into account individual differences. Education in high school, it is part of education management. Ministry of Education (2012, p. 3) said that mathematics was the cornerstone of science, theories in sciences, engineering, medicine, computer science, economics,…show more content…
Therefore, teaching and learning is very difficult. Cooperative learning, small–group learning, offers opportunities for students to be successful in mathematics. The group interaction is designed to help all members learn the concepts and problem–solving strategies. Dividing students into small group with different levels, high, medium and low level, encourages students to help and learn each other (Davison, 1990 p. 4). Cooperative learning is small group learning that allows students to work together to accomplish shared goals. Students seek outcomes that are beneficial to all. Students discuss the content and concept with each other, help each other understand it, and encourage each other to work hard (Johnson & Johnson, 1999, p. 68). Karl A. Shininger (2006, p. 37) embarked on a study to determine the benefits of using STAD in a middle school mathematics classroom. He found that Students Teams Achievement Divisions (STAD) increases academic achievement and improves students' self-esteem as learners and their social interactions with their peers. Rick Weaver (2006, p. 41) investigated the benefits of cooperative learning in the secondary math classroom. He found that cooperative learning is useful for learning mathematics in high school. The students who were exposed to cooperative learning seemed to have higher score on the tests and…show more content…
Complex number was the new content and added content by a real number. The students must be used basics knowledge to help for learning of complex number. Although students were not good to learn, there was a responsibility to come to class (Panida Phisidamornchai, 2014). The data were collected through interviews from 35 students who learned these found that complex number was difficult to understand and teachers teach not understand. Hence, test score of mathematics was not good. Some groups of students wants to group activity to help in learning because it allows the reader to get more (students,
