Abstract

Quasi experiment research with randomized control posttest group only design was carried out to determine the effectiveness of using a discovery learning based module on students learning outcome. Grade XI MIA-1 to MIA-4 students academic year 2015/2016 in SMAN 7 Padang became population of this study. Through cluster sampling technique, grade XI MIA-1 and grade XI MIA-4 were chosen as experiment and control classes respectively. The experiment class was taught using discovery learning based module in buffer solution topic while the control class was taught the same topic conventionally without the module. Research instrument used was cognitive learning outcome test with multiple choice form. Data showed that the mean test score of experiement class (78.84) was higher than that of control class (71.09). Normality and homogenity test proved that both classes were homogeneous and normally distributed. T-test, as data analysis taken, showed that t-count (3,51) is bigger than t-table (1.67). Thus, it could be concluded that students’ cognitive learning outcome in experiment class is significantly higher than that in control class. The use of discovery learning-based module in buffer solution topic was effective in increasing learning outcome of grade XI MIA students in SMAN 7 Padang.

Abstract

This study aims to produce teaching materials based material reaction rate guided inquiry (learning cycle: the phase of exploration, discovery / establishment of the concept and application) in the form of a valid experiment worksheets and practical use in learning chemistry in SMA / MA. This type of research included in Research and Development (R & D). The development model used in this study is the four-D (4-D). The research instrument is the validation sheet and questionnaire. Data from the study consists of three aspects, namely, the validity, the practicalities and effectiveness of teaching materials. Data validity and practicalities processed using Cohen's Kappa formula, and the effectiveness of data using a percentage In this study is limited to the validity and practicalities. Validation of teaching materials from the aspect of content, language and graffiti and feasibility of construction. Data from the validator obtained an average score moment kappa was 0.87, and the results of practical analysis conducted with a limited test in MAN 3 Padang obtained an average score of 0.84 practicality value of 0.78 of teachers and students. From the analysis worksheets that showed 86 % of students working on critical questions and exercises contained in LKS experiments that have been made can be answered students. These results indicate that LKS guided inquiry-based experiments developed extremely valid and practical use in learning chemistry

Abstract

This study aims to produce valid and reliable Higher Order Thinking Skills instruments in learning the biology of ecology and environment material. The research is a Research and Development study with the ADDIE model. The research was conducted at SMA Negeri Kerinci. The sample in the study came from 2 biology education lecturers and 3 biology teachers. The instruments in this study were a 20-item multiple-choice HOTS test sheet and a validation questionnaire. Data collection techniques are tests and validation questionnaires. Indicators of Higher Order Thinking Skills are the ability to analyze, evaluate and create. Data analysis is quantitative and qualitative data analysis with the help of the SPSS version 16 application. The results showed that the Higher Order Thinking Skills instrument had a validation value of 0.724 with decent criteria and reliability of 0.972 with high criteria. These findings explain that the Higher Order Thinking SSkills(HOTS) instrument is very valid and reliable for use in ecology and environmental materials.

Abstract

The aim of the study was to measure and find out the validity of the points in Science Physics questions for class VII SMP Dr. Wahidin Sudirohusodo regarding the subject matter of temperature and heat through a quantitative descriptive approach and data collection techniques which were carried out using a test technique in the form of temperature and heat questions totaling 25 items in the form of multiple choices. The population used was all students of class VII SMP Dr. Wahidin Sudirohusodo as many as 224 students spread over 7 parallel classes, 40 students were taken randomly. The sampling technique used is simple random sampling. Data were analyzed using the Anates program version 4 for windows. The results showed that the level of validity of the questions was moderate, namely 0.42. Keywords: Validity, Problem, Science Physics

Abstract

This study investigates the effect of the ethnoscience-based Science Environment Technology Society (SETS) learning model on learning Physics and Biology. This type of research involves systematic research, literature reviews, and meta-analyses. The data sources were taken from an analysis of 100 international journals published from 2018 to 2023. Tracing data sources through Google Scholar, Eric, ScienceDirect, and ProQuest. The process of selecting data sources must meet the inclusion criteria analyzed by the JSAP application. The inclusion criteria in this study are: 1) the journal must be published in 2018–2023; 2) SINTA and Scopus/WOS must index the journal; 3) The journal uses experimental or quasi-experimental research methods; and 4) it has an effect size that can be calculated. The data collection technique is direct observation through the journal database. The results showed that the average effect size (ES = 0.873) is a large criterion. These findings explain that the ethnoscience-based Science Environment Technology Society (SETS) model significantly affects science learning. Furthermore, this SETS learning model helps students learn physics and biology more actively and creatively. These results are very important in evaluating the implementation of the school learning system. Furthermore, this ethnoscience-based SETS model must be applied in learning biology and physics to stimulate students to think critically.
