Using Cooperative Learning to Develop Learning Outcome in Mathematics of Grade 11 Students

ABSTRACT

The purposes of this action research were to study mathematics learning achievement of Grade 11 students before and after being provided Student Teams-Achievement Divisions (STAD) technique, to compare mathematics learning achievement of Grade 11 students after being provided STAD technique at the expected 70 per cent criteria, and to study opinion of Grade 11 students towards STAD technique in mathematics. The participants in this study were 43 Grade 11 students in the second semester of the 2014 academic year at Debsirin School, Bangkok, Thailand. The experiment was conducted for 16 periods. The research instruments employed in this study consisted of 8 lesson plans based on the STAD technique, achievement test (IOC = 0.98, K.R.20 = 0.92) and questionnaire (IOC = 0.94). Achievement test and questionnaire were used to examine mathematics learning achievement and to study opinion of students towards STAD technique, respectively. The data were statistically analysed by using t-test for dependent samples and t-test one sample. The findings showed that mathematics learning achievement after being provided STAD technique was statistically higher than before learning at the .01 level of significance. The mathematics learning achievement after being provided STAD technique was statistically higher than the expected criteria at the .01 level of significance. Students' opinion towards STAD technique was at high level with the mean scores of 4.12. Keywords: Cooperative learning, student teams-achievement divisions (STAD), learning outcome,

learning achievement, opinion

1 INTRODUCTION

Mathematics is a subject found in all school curriculums around the world. The Ministry of Education mentioned that mathematics is one of the most important to develop human thinking skills. It enables a person to acquire skills in daily life. It is, therefore, useful to ones life, enhances quality of life and enables a person to live in harmony with others [9]. There are some problems in teaching and learning mathematics. Two main causes of these problems were a variety of students abilities and quality of teaching technique. As a result, students had still poor learning achievement and had negative attitude towards mathematics.

Davison stated that cooperative learning, smallgroup learning, offers opportunities for students to be successful in mathematics. The group interaction is designed to help all members learn the concepts and problemsolving strategies. Dividing students into small group with different levels, high, medium and low level, encourages students to help and learn each other [2]. 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 [4]. In 2006, Shininger [7] 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. Weaver [11] 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 have positive attitude towards mathematics. In [12], Zakaria et al. studied the effects of cooperative learning on students mathematics achievement and attitude towards mathematics. Student Teams-Achievement Divisions (STAD) technique was used in their research. They found that cooperative learning methods improve students achievement in mathematics and

attitude towards mathematics. The findings above were also similar to the studies of Hossain and Tarmizi, Tran, and Zakaria et al. [3, 10, 13].

Therefore, the researcher was interested in studying on using cooperative learning (STAD technique) to develop learning outcome in mathematics of Grade 11 students, in order to encourage students to have more communication, interaction and teamwork competency so that they can be successful in their work and their personal lives in the future. 1.1 Research Objectives

1.1.1 To study mathematics learning achievement of Grade 11 students before and after being provided Student Teams-Achievement Divisions (STAD) technique

1.1.2 To compare mathematics learning achievement of Grade 11 students after being provided Student Teams-Achievement Divisions (STAD) technique at the expected 70 per cent criteria

1.1.3 To study opinion of Grade 11 students towards Student Teams-Achievement Divisions (STAD) technique in mathematics

2 METHODOLOGY

2.1 Participants

The participants in this study were 43 Grade 11 students in the second semester of the 2014 academic year at Debsirin School, Bangkok, Thailand. This experiment was conducted for 16 periods.

2.2 Research Instruments

2.2.1 Eight lesson plans under the STAD technique on the topic of Complex Numbers

2.2.2 An achievement test (IOC = 0.98, K.R.20 = 0.92) consisting of 20 questions with four multiple choices

2.2.3 A questionnaire (IOC = 0.94) comprising 12 questions to evaluate students opinion towards cooperative learning (STAD technique) in mathematics

2.3 Data Collection

This study compared mathematics learning achievement of Grade 11 students before and after being provided STAD technique and compared mathematics learning achievement of Grade 11 students after being provided STAD technique at the expected 70 per cent criteria. Table 1 shows a graphic form of experimental design of this study. A represents the target group. O1 represents the pre-test while O2 represents the post-test. The STAD technique is represented as X.

The researcher conducted the study as follows: 1) The researcher taught Grade 11 students in the topic of Complex Numbers by using

STAD technique developed by Slavin [8] according to the following approaches and steps: Step 1: Introduction

Teacher divided students into group of four to five students with different levels; high (one student), medium (two students) and low (one student). Teacher identifies learning objectives and conditions for Students Teams Achievement Divisions.

Step 2: Class presentation

Teacher taught students the content following to the provided schedule with suitable techniques, activities, and learning experiences.

Step 3: Team and Quizzes

Students worked on handout in their own group. Then students took individual quizzes or other assessments such as essays or performances.

Step 4: Individual Improvement Scoring

In addition to the quiz score, the scores from tests each week were included. The scores of tests indicated the students progress of their performance. The improving scores of each student were calculated from the difference of the test scores and the base score of each student by using criteria.

Step 5: Team recognition

Team scores were calculated from the score of each group member by using criteria.

2) Opinion of Grade 11 students towards STAD technique in mathematics were collected

by using questionnaire.

2.4 Data Analysis

2.4.1 Mathematics learning achievement of grade 11 students before and after being provided STAD technique was analysed by paired-samples t test [1]

2.4.2 Mathematics learning achievement of Grade 11 students after being provided STAD technique at the expected 70 per cent criteria was analysed by one-sample t test [1].

2.4.3 Opinion of Grade 11 students towards STAD technique in mathematics was analysed by mean ( ).

3 RESULTS

The results of this study were reported following to the objectives stated earlier as follows: 1) Mathematics learning achievement of Grade 11 students before and after being provided

STAD technique Paired-samples t-test was conducted to compare the mathematics learning achievement of

Grade 11 students between before and after being provided cooperative learning model. The total score of achievement test was 20. The pre-test mean scores of students mathematics learning achievement was 4.77 (SD = 1.69), and post-test mean scores of students mathematics learning achievement by using STAD technique was 15.33 (SD = 1.48). Table 2 showed that the mean of the post-test ( = 15.33) was greater than that of the pre-test ( = 4.77). The difference between pre-test and post-test mean scores was signi
