0 likes10 views
This document summarizes a research study that analyzed the effectiveness of a constructivist instructional approach on student achievement in mathematics compared to a traditional approach. Sixty students participated in the study, with the experimental group receiving instruction through constructivist methods while the control group used traditional methods. Students were tested before and after using an achievement test, and results were analyzed using ANOVA and ANCOVA statistical techniques. The study found that the constructivist approach led to significantly higher achievement scores compared to the traditional approach. Additionally, the constructivist approach was equally effective for both male and female students. Therefore, the study concluded that a constructivist instructional model is more effective for teaching mathematics than a conventional teaching method.

VIDYA R NAIR Mathematics ------------------------------------------------------------------------***----------------------------------------------------------------------- ABSTRACT:- The research was undertaken to analyze” EFFECTIVENESS OF CONSTRUCTIVIST INSTRUCTIONAL APPROACH ON ACHIEVEMENT IN MATHEMATICS AMONG STUDENTS. “The study was conducted on a sample of 60 students. The design selected was pre- test post-test non-equivalent group design. The constructivist instructional approach was used in the experimental group and the traditional approach was followed in the control group. An Achievement test was also prepared to test the effectiveness of each group under study. The technique of Analysis of Covariance (ANCOVA) was used to test the equivalency between groups. Mathematics teaching through constructivist instructional approach was found to be more effective than the conventional method. Key terms Constructivism, Constructivist Instruction, Traditional instruction, Academic achievement, Problem-Solving skills. INTRODUCTION Mathematics is universally practiced and applied by human beings and it is being and becoming part of our life. The core process of teaching is the arrangement of the environment with in which the student can interact. This need led to a variety of approaches to design instruction along with teaching learning situation to achieve specific instructional objectives. The functional and structural guidelines to design instructional materials and environment came forward as models of teaching. It is a step by step procedure that leads to specific learning outcomes. Constructivist learning environments provide multiple representations of reality. Which is the main principle of child-centered education. By this approach, people get more information.it is the process based on observation and scientific study.it focusses knowledge construction but not reproduction. It helps students to establish facts, build concepts and then generate explanations of theories that explain the phenomena under consideration. This model lays stress on understanding the content and process of mathematics. The learners are actively involved and it is a student centered process. This process helps in collaborative knowledge construction. Constructivist instructional approach means teacher guides and facilitates the lesson like a mentor. It is based on observation and scientific study. Traditional instruction means general teaching method. Students construct knowledge through our experience. Academic achievement is the short term or long term educational goal. Problem solving is the process of finding solutions to difficult problems. SCOPE OF THE STUDY 1) It is expected that the finding of the study will help the curriculum planners to make needed changes in the content of Mathematics text book. 2) It will also help teachers to understand the effectiveness and necessity of the application of constructivist approach in the teaching of Mathematics. 3) The findings of the present study will help to find new frontiers to educational practices. STATEMENT OF THE PROBLEM The present study is an attempt to check the effectiveness of Constructivist approach in teaching Mathematics over Conventional method. Hence the problem is stated as, Effectiveness of constructivist instructional approach on achievement in mathematics among students.

OBJECTIVES 1) To analyze the performance of the pupils before the conduct of the experiment. 2) To analyze the performance of the pupils after the conduct of the experiment. 3) To find the effect of Constructivist approach on student achievement. 4) To compare the total achievement of pupils who were taught through Constructivist approach with that of pupils who were taught through the conventional method of teaching. RESEARCH METHODOLOGY Experimental method was selected for the present study. In that, the design selected was pre-test post-test non-equivalent group design. The study was conducted on a sample of 60 students. And both quantitative and qualitative data analysis techniques for the data collected. The data collected from the pre-test and post-test scores were analyzed by the above methods. The constructivist instructional approach was used in the experimental group and the traditional approach was followed in the control group. The equivalent group design would have been a very comprehensive design of the experiment. Technique of Analysis of Covariance (ANCOVA) was used to measure the equivalency between groups. Both the group were given pre-test and post-test. Pre-test was administered to both control group and experimental group to identifying their initial cognitive level. Then, the post test was conducted to analyses the achievement score.

It became necessary to analyze the data by using the statistical technique called ANCOVA in which the difference in the initial status of the 2 groups can be removed statistically so that they can be compared as though their initial status had been equated. Genuiness of the differences in performance COMPARISON OF ACHIEVEMENT OF MATHEMATICS OF EXPERIMENTAL AND CONTROL GROUPS BASED ON PRE-TEST AND POST -TEST SCORES USING ANCOVA. Before proceeding ANCOVA, ANOVA was done.

The obtained FYX is greater than the table value; it is significant at 0.05 levels. 2) Comparison of the post-test scores of Girls and Boys in the Achievement in Mathematics when taught through Concept Mapping Two sample t- tests were used for testing the equality of the post-test scores of boys and girls belonging to the experiment group. THE DATA AND RESULT OF THE TEST OF SIGNIFICANCE OF THE POST-TEST SCORES OF BOYS AND GIRLS IN EXPERIMENTAL GROUP GROUP N MEAN SD CRITICAL RATIO TABLE VALUE REMARK GIRLS 15 10.67 2.23 1.58 0.05 0.01 NO SIGNIFICANT DIFFERENCE 1.96 2.58 BOYS 15 9.33 2.43 Arithmetic mean score of girls and boys in the experimental group is 10.67 and 9.33 respectively. The mean value signifies that there is slight significant difference between post test scores of girls and boys in the experimental group. S.D of girls is 2.23 and that of boys is 2.43. It shows that the values are not scattered very much. The obtained t value is 1.58 is not significant. The table value of t at 0.05 level is 1.96. So from the analysis of data, it may be concluded that there is no significant difference in the effectiveness of constructivist approach in the achievement of scores in Mathematics among girls and boys.
