FACTORS AFFECTING STUDENT ACCEPTANCE OF EVOLUTION THEORY BASED ON GENDER AND EDUCATIONAL BACKGROUND: a case study in Universitas Islam Madura, Indonesia
Full text linkEvolution is one area on Biology learning that has the most contravention and misconception for many students in various educational regions globally, including Indonesia. This study aimed to identify student's acceptance of the evolutionary theory. The study was conducted using a mixed-method, in which the results of descriptive research were followed by correlational research on the variables studied. Data were collected by using questionnaire and rubric of Measure of Acceptance of The Theory of Evolution (MATE). The results showed that the average MATE score was 65.05, in which the students tended to have a moderate level of the acceptance of the evolutionary theory. The result showed that sex and religious background correlated with students' acceptance of the evolutionary theory, with a contribution of 49.9%. Thus, these results suggest that evolution is a crucial aspect to be considered in teaching evolution, and there must be an effort to overcome the differences in the acceptance of evolutionary theory in students with different gender and educational backgrounds. Three other factors influence student acceptance of the theory of evolution, namely students' misconceptions, beliefs, and understanding of the nature of science. Therefore, identification of students' prior knowledge is needed to determine the factors that influence students' acceptance in a context

IMPLEMENTATION OF PROJECT ORIENTED PROBLEM-BASED LEARNING (POPBL) MODEL INTEGRATED WITH STEM TO ENHANCE JUNIOR HIGH SCHOOL STUDENTS' SCIENCE CONCEPT MASTERY
Full text linkThe low ability of students to solve problems is in line with the low mastery of science concepts. In this study, Science, Technology, Engineering, and Mathematics (STEM) integrated Project Oriented Problem Based Learning (POPBL) learning models were implemented to improve the mastery of science concepts of junior high school students, especially on the topic of Environmental Pollution. The method used was a mixed-method. The STEM integrated STB learning model design framework consists of 3 stages: Onset Stage, Execution Stage, and Closure Stage. The concept of students is emphasized at the onset stage in the case study dissemination phase. In this phase, students analyze problems based on articles provided by the teacher. The more understanding the material, the more critical students will explore existing issues and find logical solutions to those problems. The results showed that there was a difference between the average pretest and posttest learning outcomes (t=-5,660; df = 53; Sig. (2-tailed) = 0,000). This indicates an increase in junior high school students' science concepts mastery after using the STEM integrated POPBL Learning Model. Improving students' mastery of concepts using a STEM integrated POPBL learning model is still in the low category with n-gain = 0.17. Although still in the low category, the POPBL learning model with the STEM approach can be optimized to improve students' mastery of concepts and skills on other science topics
TEACHING MADURA LOCAL CONTENT LITERACY ON PRESERVICE SCIENCE TEACHER USING LWIS MODEL
Full text linkSeveral previous studies have shown that students have difficulty integrating ethnoscience into science learning. Students are more likely to be introduced to the basic concepts of ethnoscience without involving how to integrate ethnoscience into science learning. The impact is that students’ scientific literacy is low. This is what underlies researchers to apply the Local Wisdom Integrated Science (LWIS) learning model by using local Madurese content to train students’ scientific literacy. The aim of this study was to evaluate differences in student scientific literacy after implementing the LWIS learning model in ethnoscience learning with local Madurese content. The method used was pre-experimental study with one group pretest-posttest design. When the study was carried out in the even semester of the 2019/2020 academic year by taking 22 students via purposive sampling technique as a sample of all students in class 6A of science education, Trunojoyo University, Madura. Analysis of data using descriptive statistics and paired sample t test. The results showed that there were different in the scientific literacy of the students using the LWIS learning model before and after studying ethnoscience with local Madurese material. The entire LWIS syntax helps train students' scientific literacy by including self-awareness of the importance of local Madurese content as a learning context. Ethnoscience can be integrated into science learning through the STEAM approach. The contribution of STEAM to the LWIS learning model and self-awareness is very significant in developing ethnoscience learning for local Madurese content from elementary, middle, and tertiary level.
