The Development of Scientific Problem-Solving Ability through Learning Activities Based on the HALO Model for Second-Grade Students

Abstract

The objectives of the research were 1) to develop learning activities based on the HALO model concept;
2) to examine the scientific problem-solving ability included 2.1 to compare the difference in the scientific
problem-solving ability before and after learning, 2.2 to study the scientific problem-solving ability development; and 3) to investigate the student’s satisfaction. This research was action research. The sample consisted of five second-grade students at Ban Khaoklang, Bunkrik district, Ubon Ratchathani province during the second semester of the academic year 2022, determined by purposive sampling. The research instruments comprised of lesson plans for the learning activities, a scientific problem-solving ability test, and a questionnaire about the student’s satisfaction. Statistics used for data analysis were mean, standard deviation, and relational development scores.

            The results revealed that 1) the learning activity development based on the HALO model concept
consisted of 5 steps: 1) preparing learners, 2) setting learning observation, 3) learning activities, 4) summarizing knowledge, and 5) applying knowledge. The learning plan assessment showed the highest level of suitability with an average score of 4.60. 2) Results of the study of scientific problem-solving ability found that
2.1) the student’s scientific problem-solving ability improved after learning having an average relativity development score of 55.25%, 2.2) the development score of the scientific problem-solving ability was higher after learning and 3) results of the study of student satisfaction with the learning activities overall was at the highest level with an average score of 4.75 and the standard deviation score of 0.37. It shows that learning activities based on the Halo Model concept can develop the ability to solve scientific problems to a higher level and the students are satisfied at the highest level.
