PENINGKATAN HASIL BELAJAR SISWA PADA MATERI IKATAN KIMIA MELALUI PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEAD TOGETHER (NHT) BERBANTUAN MODUL DI KELAS X SMA NEGERI 10 AMBON

Research has been conducted to determine student learning outcomes in chemical bonding material by applying the cooperative learning model type Numbered Head Together (NHT) with the help of modules, in class X students of SMA Negeri 10 Ambon. This type of research is quantitative descriptive. Based on the analysis of the data obtained 12 students (40%) get very good qualifications, 10 students (33.3%) get good qualifications, 6 students (20%) get enough qualifications, and 2 students (6.7%) get less qualifications. The acquisition of N-gain value is 18 students (60%) in the high category and 12 students (40%) are in the medium category. The results of the normalized gain score analysis of the average of all students amounted to 0.71 are in the high category. These results indicate that the application of the NHT (numbered heads together) cooperative learning model with the help of modules succeeded in improving student learning outcomes in all aspects (cognitive, affective, and psychomotor

CAN THE ETHNOSCIENCE-BASED INQUIRY LEARNING MODEL IMPROVE STUDENTS’ SCIENCE PROCESS SKILLS?

This study aims to determine the increase in students' science process skills by applying an ethnoscience-based inquiry learning model to colloid system material from a public high school in West Seram. The type of research used is descriptive-quantitative. The sample used in this research was 30 students in class XI IPA. Data collection techniques in this study were test techniques in the form of a pre-test and a post-test. The results showed that the application of the ethnoscience-based inquiry learning model succeeded in improving students' science process skills, with an increased score calculated based on the results: the average value before learning was 26.29 and increased after learning with an average value of 80.50. The average value of N-gain is 0.74, indicating an increase in students' science process skills in the high category. Encouraging chemistry teachers to explore other ethnosciences to teach colloid systems is necessary

PENERAPAN PENDEKATAN INKUIRI BERBASIS KONTEKSTUAL PADA KONSEP HIDROLISIS GARAM DI SMA NEGERI 11 AMBON

Research had been done to know the increase of student learning result on Salt Hydrolysis Concept with application of inquiry approach based on contextual teaching and learning in Grade XI class SMA Negeri 11 Ambon. This research is quantitative descriptive research, as sample is students in XI IPA1 class. While the post test showed that 29 students (96,67%) are able to reached Complete Criterion Minimum (KKM) already decide by that school. The application of inquiry approach based on contextual teaching and learning can support students’ activities in teaching learning process and made students to think critically and be creative to increase students learning resul

The Development of Local Wisdom-Based Chemistry Modules to Improve Students' Science Process Skills

Process skills are essential skills that must be possessed in the chemistry learning process. It is because science process skills are needed in conducting scientific investigations. This study aimed to develop a chemistry subject module based on local wisdom and its effectiveness in improving students' science process skills. The research subjects were 30 eleventh grade senior high school students. This development research used the Borg and Gall model (2003), which adapts the Dick and Carey model, named Instructional System Design which includes ten stages of development. The product of this research and development is a chemistry subject module for the subject of colloid systems. Furthermore, the developed module received a validation test using a questionnaire given to experts and users to determine its feasibility in learning. The results of feasibility validation by learning media experts obtained a percentage of 100%, by chemists on the chemical material presented in the module content of 91%, by chemistry learning experts with a percentage of 82.50%, by 10 students with a percentage of 91.43%. Thus, the module developed is very feasible to be used in learning. After getting validation, the science process skills test results were analyzed on the initial and final tests using the Normalized Gain (N-gain) technique to determine its effectiveness in improving students' science process skills. Data analysis was obtained through one group pre-test and post-test design. Then, the results of the N-gain analysis of 0.74 are categorized as "High." It means that there is an increase in students' science process skills after applying the module. Thus, it can be concluded that the chemistry subject module is suitable for use in learning and affects the effectiveness of learning because it can effectively improve students' science process skill
