Development of Chemical Practicum Private Vocational School of Senior High School XII Class Based on Projects and Characters

摘要

This research is descriptive with the aim of developing project-based chemistry practicum guides and the characters of Redox and Electrochemical Reaction materials according to BSNP standards. The sample consisted of 2 lecturers and 2 chemistry teachers, 30 students experimental class and 30 students control class at the Medan~(6th) Senior High School, three practicum guides of Erlangga (A) publishers, Bumi Aksara (B), Duta Nusantara (C),. The study used the ADDIE method and the data was processed descriptively. Questionnaires distributed to the leacturer and teacher samples and found that content, language, presentation, and graphycs feasibility scores were 3.53., 3.46., 3.50., and 3.53 respectively, the average score was 3.32., which means that the practicum guide developed is very valid. Data analysis with ANOVA, obtained the average scores of student outcomes in experimen class was higher than control class or 81.5% > 73.8%. Then the average phsychomotor scores of experimen class was larger than control class or 84, 64 > 82.78. In addition, the affective scores of experimen class was larger than control class or 78.42 > 76.38. The hypothesis tested with one way ANOVA at the significant level of α 0.05, and found that t_(count) > t_(table), (4.536 > 1.697). It is concluded that the Innovative Chemistry Practicum Guides developped is highly very good, suitable for use in Senior High School.
