The Effectiveness of Teaching Materials Loaded with Blended Learning with a Scientific Approach on Buffer Solution Learning

The 2013 scientific-based curriculum, teachers must facilitate students to gain knowledge or skills based on the scientific method. The research aims to analyze the effectiveness of teaching materials. This type of research development, teaching materials have valid content and media. Teaching materials are declared effective if there is an increase in students' classical mastery, an increase in the achievement of basic competencies, and students can understand macroscopic, microscopic and symbolic level representations. Quantitative descriptive research method, starting from the analysis of the quality of teaching materials and diagnostic test instruments Two Tier Multiple Choice (TTMC), application of teaching materials, application of questions, data analysis of test results, classical completeness, achievement of basic competencies, and analysis of representational understanding. The research subjects were students of class XI and XII MIPA. The results of the study were obtained from the results of the student's TTMC test on the buffer solution material that had used Teaching Materials. Data analysis was done classically. The results showed that there was an increase in classical completeness by 9%, the achievement of basic competence indicators increased by 8% and concept understanding increased by 6%. So that the teaching materials developed are effective to use.

FMCE-PHQ-9 Assessment with Rasch Model in Detecting Concept Understanding, Cheating, and Depression amid the Covid-19 Pandemic

This research aims to see the ability of the FMCE-PHQ-9 test instrument amid the Covid-19 pandemic to measure conceptual understanding, cheating, and depression in students. The research was conducted on 64 physics education students at Sulthan Thaha Saifuddin State Islamic University Jambi. The instrument consists of 47 force and motion material items to fit the Winsteps 3.65.0 program. The analysis results using the Rasch Model showed that the MNSQ Outfit was 1.00 in the person column and 0.1 in the item column. Judging from the ZSTD value of 0.57 for the person and 0.1 for the item, the Points Measure value correlated with 0.4 to 0.85 while the item reliability value was 0.73 and the Cronbach's Alpha value was 0.56. therefore, the test instrument using the Rasch proclamation model found 31 fit items. The analysis results show that the concept ability was poor since, on average, the students could only answer questions with a low index of difficulty category. The research results on the level of cheating obtained data that 100 percent of students were not indicated to have the same pattern. Lastly, for the level of depression, only 16 percent of students did not experience depression, while 84 percent of students experienced it.

A Thematic Review on Exploring Ethnoscience in Science Education: A Case in Indonesia

This study aims to review the ethnoscience studies in science education in Indonesia thematically. From 2010 to 2020, the databases contained 71 relevant articles of ethnoscience studies. These studies belonged to the content analysis theme parameters of method/design, sample, data collection, data analysis, topic, result, recommendation, and location. The results indicated that most of the ethnoscience studies explored the effect of integrating ethnoscience with the lessons to investigate students’ achievement and attitudes towards science. Correspondingly, the investigated studies mostly used Research and Development (R D) and experimental research design. The preferred data collecting techniques were tests (multiple-choice/description), questionnaires, and observation. Moreover, seventh and eighth graders of junior high school commonly employed the argumentation activities in physics, chemistry, biology, and basic concept of science topics. This study suggests the teachers employ different methods (e.g., ethnoscience) to improve concept understanding, problem-solving skills, critical thinking skills, and motivation in learning science from the primary school level. Furthermore, resources from cultural activities in Indonesia are beneficial for integrating ethnoscience in learning.

PENGARUH PEMBELAJARAN INKUIRI TERBIMBING TERHADAP PEMAHAMAN KONSEP FISIKA PESERTA DIDIK

This research was conducted with the aim of knowing whether there was an effect of guided inquiry learning on students' understanding of the concepts of physics. By using a quasi-experimental research method with. Non-Equivalent research design. Control Group Design in order to obtain two class groups, namely the experimental and control groups. Data were collected using an objective test of concept understanding in the form of a multiple-choice test with five choice options. The data obtained were then tested the prerequisites first. After the data is said to be distributed normally and homogeneously, it is followed by hypothesis testing using the t-test. The t-test result shows that the significance value is smaller than the α value (0.000 <0.05), so that Ho is rejected and Ha is accepted. Which means that there is an effect of understanding the concept of physics between participants being taught learning guided inquiry and being taught conventionally.
