DEVELOPING A PHYSICS INSTRUCTIONAL PACKAGE BY USING 5E INQUIRY-BASED LEARNING CYCLE MODEL COMBINED WITH PROBLEM-SOLVING PROCESS AND KWDL TECHNIQUE FOR MATHAYOMSUKSA 5 STUDENTS: ENHANCING INTEGRATED SCIENTIFIC PROCESS IN THE STUDY OF LIGHT AS WAVES AND ELECTROMAGNETIC RADIATION

Abstract

The objectives of this research article were: 1) To develop a Physics Instructional Package. 2) To determine the efficiency of the Physics Instructional Package, ensuring it meets the 80/80 criteria for effectiveness. 3) To ascertain the effectiveness index of the Physics Instructional Package, aiming for a value of 0.50 4) To compare students' learning achievements before and after using the Physics instructional package. 5) To compare the integrated science process skills of students before and after using the Physics Instructional Package. 6) To study the students’ satisfaction with the Physics Instructional Package. This quasi-experimental study was conducted with The sample group comprised 35 students from M.5/4 in the first semester of 2024 from Surat Thani School, under the Secondary Educational Service Area Office Surat Thani-Chumphon, This group was selected using the cluster random sampling method. The research employed a One Group Pretest-Posttest Design. The data collecting tools include: 1) the developed learning activity set, 2) lesson plans, 3) an activity alignment evaluation form, 4) an academic achievement test, 5) an integrated scientific process skills test, and 6) a student satisfaction questionnaire. The results showed that: 1) 10 sets of the Physics Instructional Package consisted of guidelines for teachers and students, learning procedures, learning outcomes, pre- and post-tests, activity sheets, knowledge sheets, exercises, references, and answer keys were developed, achieving an Index of Item Objective Congruence of 0.95. 2) The Physics instructional package had an efficiency value (E₁/E₂) of 83.07/81.24. 3) The Physics instructional package's effectiveness index was 0.74. 4) There was a statistically significant increase in learning achievement scores at the .01 level. 5) There was a statistically significant improvement in Integrated Science Process Skills scores at the .01 level. and 6) The students expressed a very high level of satisfaction with the Physics instructional package.
