Development of the Learning Science Model Using Case-Based Learning and Problem-Based Learning to Enhance Problem-Solving Ability for Prathom Suksa 4 Students

Abstract

            The purposes of this research were: 1) to study the data and need assessment for the development of the learning science model; 2) to develop the learning science model using case-based learning and problem-based learning to enhance problem-solving ability which an efficiency level is at 80/80; 3) to evaluate the effectiveness of the learning science model using case-based learning and problem-based learning to enhance problem-solving ability. The samples were 22 students of 4th-grade students who studying in semester 1 of the academic year 2020 at Baan Srimongkol Municipality School. The instruments in this research consisted of 6 instruments as follows: 1) learning science model using case-based learning and problem-based learning to enhance problem-solving ability, 2) handbook for the model, 3) lesson plans, 4) solar system knowledge test, 5) problem-solving ability test, and 6) satisfaction evaluation of the student through learning model. The data were analyzed by mean, standard deviation, one sample t-test, and content analysis. The research findings were as follows:
            1.  The learning science model using case-based learning and problem-based learning to enhance problem-solving ability named “URACE Model” consisted of five elements: 1) principles - learning by using case - situation or problem - to motivate outside classroom study and discussion in the class, 2) objective - developing knowledge, problem-solving ability, 3) the learning process which had five steps, i) Understand: U ii) Reviewing: R (iii) Analyzing: A (iv) Conclusion: C (v) Evaluate: E, 4) The measurement and evaluations consisted of solar system knowledge test and problem-solving ability test, and 5) criteria and conditions for using the URAEC model consisted of the instructor should prepare media and case which related to student’s life, students have to easily access through technology, and a student should have the responsibility to the outside classroom study. The selection of case studies and problems must be consistent with the learners. The efficiency of the URAEC model is at 83.46/85.77.
            2.  The effectiveness of the URACE Model revealed that 1) the result of the solar system knowledge test after using the URACE model found that students’ knowledge ( = 26.36, S.D. = 1.56) were statistically higher than before using the model at a .05 significance level, 2) the students' problem-solving ability was higher than 70 percent of the criterion ( = 84.09, S.D. = 4.76), and 3) the satisfaction of the students with the URACE model was at the high level ( = 4.38, S.D. = 0.53).
