Inquiry-Oriented Learning Material to Increased General Physics Competence Achievement

Abstract

This study aims to produce inquiry-oriented general physics learning material to improve student learning outcome. Development steps of learning materials were adapted from the design model of Dick and Carey. Stages of development consists of three phases: planning, development, and formative evaluation and revision. Implementation of formative evaluation involves three expert reviewers, they are subject matter experts, general physics lecturer, and media experts; one-to-one evaluation involved three students, evaluation of small groups involve 15 students, and a field test (effectiveness test) involve 30 students. The structure of the contents of the learning material refers to the concept of scientific investigations which generally consists of: stating the problem in a question form, formulating the hypothesis, literature, testing the hypothesis, analyzing the result and writing the conclusion. The result obtained from subject experts, general physics lecturer and media expert are in a good categories with their respective ideals for each are 80.2%, 82.7% and 84.5%, an increase competency achievement of pretest and postest on field tests in the medium category <g = 0.67>, and the results of student responses to the instructional materials belonging to the positive response with a score of 73.5%. These results illustrate that the inquiry-oriented general physics learning material has a good criteria and suitable used as learning materials.
