SDL Effectiveness with Student Centered Approach to Self Efficacy and Mathematical Reasoning

Abstrak

The research aims to find the effectiveness of the self-direct learning model with the student centered approach rather than the conventional learning model of self efficacy and the ability of mathematical reasoning on derivative material. The population in this study is the students of class XI SMAN 5 in 2022/2023 academic year. The sampling retrieval technique in this study uses a random sampling cluster technique. A sample of 105 students are taken that consists of three classes. The data-collection techniques used are interviews, documentaries, questionnaires and tests.  The research instrument is a Self Efficacy questionnaire and a test of learners ability of mathematical reasoning which have already tested its validity and reliability at a 5% significant level. The techniques used for data analysis are tests of proportion, one sampe t test, independent t test, manova test and  hotelling test that have previously been carried out the prerequisite test of normality and homogeneity. The results of the study reveals that the model of self direct learning with the student centered approach towards self efficacy and the ability of mathematical reasoning is more effective than the conventional learning model.
