Abstract

This research purposed  to know the influence of using advance organizer model to students’ biology achievement in protists concept. This research was used quasi experiment method with pretest-posttest control group design. The data analysis was used t-test, from the result of calculating mean differentiation of posttest both groups, obtained the value of t-count was equal to 3,087, while t-table at the level of significant 5% with degree of freedom (df) = 78 that was equal to 1,67. So, it can be said that t-count > t-table that means the alternative hypothesis (Ha) was accepted and the zero hypothesis (H0) was refused. It showed that there was influence of using advance organizer model to students’ biology achievement in protists concept.

Abstract

The problem of low science literacy needs to be used as a reference by the government in improving the learning system in Indonesia. This study aims to produce teaching materials in the form of STEM-Based Electronic Student Worksheets (E-LKPD) to Improve Science Literacy Skills in Environmental Change Materials. The method used is Research and Development (R&D) with a 4-D development model (Define, Design, Develop, and Disseminate). The development process goes through a validity test of 2 experts, a readability test of 15 students, and a field trial by 1 biology teacher and 35 students. The results of the study showed that the developed E-LKPD had an average validity percentage of 85.2% with very feasible criteria. In the readability test, the average percentage of E-LKPD reached 86.2% with very feasible criteria. While in the field trial, the responses of teachers and students showed very feasible criteria with percentages of 81.25% and 82.25%. There was an increase in the average creative thinking ability measured through the test instrument. The average result of creative thinking ability before the implementation of E-LKPD was 57.3 while after the implementation of E-LKPD it increased to 79.6 with an N-Gain of 0.50 in the moderate category. Based on these results, it can be concluded that E-LKPD is very feasible to use in learning activities and there is an increase in scientific literacy skills after the use of E-LKPD in the learning process.

The development process goes through a validity test of 2 experts, a readability test of 15 students, and a field trial by 1 biology teacher and 35 students. Pretests and posttests were conducted using multiple-choice test instruments consisting of the same 10 questions. The results of the research showed that the developed E-LKPD had an average validity percentage of 85.2% with very feasible criteria. In the readability test, the average percentage of E-LKPD reached 86.2% with very feasible criteria. While in the field trial, the responses of teachers and students showed very feasible criteria with percentages of 81.25% and 82.25%.
