Abstract

This study investigated conceptual change in students’ understanding of ecosystem concept. The PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching strategy, a variant of classical POE (Predict-Discuss-Explain) was implemented during the study. Sample was 28 senior high school students in one of senior high school in Bandung. Students’ ideas about ecosystem concept were revealed by a ten questions-test called ECT (Ecosystem Conceptual Test). Conceptual change in student’s understanding of ecosystem concept was evaluated by administering ECT in pretest, posttest, and delayed posttest.Tests’ score were then analyzed quantitatively and qualitatively. One-way ANOVA test result showed statistically significant score difference (p<0.05) in each test which suggested PDEODE helped the students to achieve better understanding. Moreover, no statistically significant differences were found between posttest and delayed posttest scores, indicating that the teaching strategy helped the student to retain their new conceptions.ABSTRAKPenelitian ini menyelidiki perubahan konseptual pada pemahaman siswa tentang konsep ekosistem.Variasi dari strategi pengajaran POE (Predict-Discuss-Explain) yakni PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) diterapkan selama penelitian ini.

Abstract

Based on PISA 2018 result, the science achievement of Indonesian students was below average. Some factors influence students' achievement in learning science, such as motivation, emotion regulation, self-efficacy, and school system. This study investigates students' self-efficacy in learning science in different school systems. The present investigation aims to discover students' self-efficacy levels in public and private schools. By looking at students' self-efficacy levels, this study determines its correlation with science achievement. There were 170 public school students and 107 private school students in Bandung City involved in the study. This study employed a correlational research design to determine the correlation between two variables. The correlation analysis was done in each school. Thus, Spearman-rank correlational analysis was used to investigate the correlation between the two variables in three public schools and two private schools. Also, Person-correlational analysis was used for the other private school. The results show that students' self-efficacy in public and private schools was in the medium levels. Seventy-eight point eight public-school students and 76.6% of private school students were classified at the medium level. However, there was no correlation between students' self-efficacy and their achievement in learning science both in public and private schools.

Abstract

The objectives of this study were to profile the relationship of scientific attitude level and learning style preference among junior high school students in Bandung. This study utilized a survey research design with a total sample size of 110 students. A scientific attitude questionnaire and a visual, auditory, and kinesthetic (VAK) learning style inventory were administered in this study. The questionnaire measures five aspects of scientific attitude, specifically rationality, curiosity, open-mindedness, aversion to superstition, and objectivity. The VAK learning style inventory evaluates the preferred means of receiving sensory information. The scientific attitude questionnaire provided consistent results, as indicated by its reliability coefficient (0.896). The results show that junior high school students have an average level of scientific attitude and generally prefer a kinesthetic learning style.  There was a medium relationship between scientific attitude and learning style among the students (Cramer’s V coefficient = 0.239).  It is concluded that learning style must be considered in implementing a science lesson, especially in the Indonesian context.
