The Effectiveness of Geopark-Based Science Learning to Increase Students' Concern for The Local Environment and Culture the Belitung Island

Research to know the effectiveness of science learning at the Geopark-based elementary school (SD) stage on Belitung Island which includes geological diversity (Geodiversity), biodiversity (Biodiversity), and cultural diversity (Cultural diversity). The type of research applied is experimental research with a one-group pretest-posttest design. The sample selected was elementary school students in grades IV, V, and VI with each class using a large scale. The instruments used were pretest and posttest to determine student learning outcomes in geopark-based science learning both before and after the learning process. In this study, questionnaires were also used to collect qualitative descriptive data. The research results for grade IV geological diversity on granite teaching materials show that Geopark-based science learning is effectively applied in the high category and for Lake Kaolin teaching materials show that Geopark-based science learning is effectively applied in the medium category. The results of the research for Biodiversity for class V Mangrove Forest teaching materials show that Geopark-based science learning is effectively implemented in the high category and for Kabong Tree or Enau teaching materials it is shown that Geopark-based science learning is effectively applied in the medium category. The results of the study for cultural diversity (Cultural diversity) for class VI on Marastaun Culture teaching materials show that Geopark-based science learning is effectively applied with medium category and for Nirok Nanggok Culture teaching materials shows Geopark-based science learning is effectively applied with high category. The research recommendations show that development in the form of Geopark-based science teaching materials needs to be followed up for learning in the Geopark area which is a source of the nation's natural wealth.

The Effect of Brain-Based Learning (BBL) Model with Audiovisual Media on Student's High-Level Thinking Ability

The purpose of this study was to obtain scientific information about students' higher-order thinking skills with the Brain-Based Learning (BBL) learning model using audiovisual media guided by students' learning motivation to develop teaching materials, especially in science subjects "substances and mixtures", as well as to measure the validity, practicality, and effectiveness of science learning. The design used in this study is quasi-experimental. by using a pretest and posttest control group design. However, before the pretest, the questions tested had been tested for homogeneity considering children’s different abilities. This design involves two classes, namely the experimental group class and the control group class. From the results of the study, there are differences in students' higher-order thinking skills between classes using the Brain-Based Learning (BBL) model and types using conventional methods with an average post-test score of higher-order thinking skills using the Brain-Based Learning (BBL) model of 87,044 and the average posttest value of higher order thinking skills with conventional methods is 77,193.

Science teacher’ leadership styles and competencies from the perspective of high school students: A path analysis study

Science teachers’ leadership styles and competencies were very important for science learning caused those to have a strong impact on learning outcomes and determine school effectiveness. This study was aimed to investigate the influence of leadership style variables on teacher competence and effective learning based on students’ perspectives. This research was survey research with a quantitative approach. Participants of this study were 243 senior high school students majoring in Science at SMAN (Sate Senior High School) 1 Metro, SMAN 2 Bandar Lampung, and SMAN 3 East Lampung. The data on teacher competencies and effective learning was collected using a questionnaire with a Likert scale of 5 options and the data on leadership styles was collected using a questionnaire developed by Northouse (2011). The data analysis techniques used were the path analysis. This study obtained several findings, namely: democratic leadership had a significant effect on teacher competence while laissez-faire leadership had no significant effect on teacher competence; there was a positive and significant influence between teacher competence (professional, pedagogic, personality, and social) on the effectiveness of science learning; and there was a positive and significant influence of the democratic leadership style on the effectiveness of science learning while the laissez-faire leadership style did not have a significant effect on the effectiveness of science learning. Based on the finding, schools need to pay attention to science teachers’ leadership styles and competencies, teachers should have democratic leadership styles in learning.

SCIENCE LEARNING MODEL TO IMPROVE NATURALIST INTELLIGENCE FOR EARLY CHILDHOOD

This research aims to commonly analyze the implementation model of science learning for early childhood, and presets the illustration about naturalist intelligence on early childhood. This research is also explained the effectiveness from the implementation model of science learning to improve naturalist intelligence in TK (Kindergarten) Masjid Syuhada Yogyakarta. This research uses qualitative research method which is directed to field research. The data that are used to this research are obtained from observation, collecting from field, interview, and documentation. Based on the research result, it can be concluded that; Firstly, the methods in implementing the science learning for early childhood in TK Masjid Syuhada use methods such as playing, telling story, exemplary, habituation, excursion, demonstration, project and question and answer method. Secondly, naturalist intelligence that can be seen from the science learning is that the children can identify animals and plants around them, they have high interest to the others and nature preservation, love about farming, care to the pets, love to have excursion in nature, love to study about nature, animals as well as plants. Third, the effectiveness in the implementation of science learning to improve children’s naturalist intelligence is curriculum improvement in TK Masjid Syuhada. They are intracurricular and extracurricular learning and basic learning that including basic education in TK Masjid Syuhada as well as evaluation. Effectiveness of science learning can be seen from the evaluation of children’s learning result and their expression, enthusiasm or sprit of the children when following every learning process given by the teacher, and the materials that are supporting the learning process as well as the creativity and innovation of the teacher.
