Abstract

This study aims to improve student learning outcomes on chemistry subjects by applying the Teams Games Tournament (TGT) learning model for tenth-grade students. The method used is classroom action research that is carried out in three cycles, each cycle consisting of two meetings. Techniques of data collecting use the observation sheet and final testing cycle. Observation sheet was used to determine the activity of students and the test to determine student learning outcomes. Based on research, gained mastery learning outcomes of students increased from 45% before treatment (T0) to 55% in the first cycle (T1), 72.5% in the second cycle (T2) and 87.5% in the third cycle. Average student activity within the group at the first cycle of 53.43%, 57.18% for the second cycle and the third cycle of 64.47%. Average student learning outcomes at the first cycle of 70, 55, 72,125 for the second cycle and the third cycle of 74,6. Cooperative learning strategies are effective when the curricular knowledge taught in the school is drawn from all groups by playing. Based on these results, the researchers suggest to teachers who have the same problem in learning can apply learning model Teams Games Tournament (TGT).

Abstract

The application of technology in education in the 4.0 era can make it easier for students to build their knowledge. The model of this research is the Research and Development of Borg and Gall which was modified by Sukmadinata (2006) conducted to describe the development of a Tringo-based digital worksheet that is suitable for use in lectures on Natural Sciences III to increase students' lifeskill. This article discusses the Develop phase. Data collection techniques using a questionnaire technique. From the results of the study it can be concluded that the Digital Worksheet is appropriate to be used in Science III lectures with the average results of expert validator ratings on each aspect as follows: content worthiness of 32.25 (Very Good), Conformity of presentation with learning approaches of 36 (Very Good), Conformity with didactic requirements is 18.5 (Very Good), Conformity with construction requirements (linguistic) is 20 (Good) and Conformity with technical requirements (graphic) is 26.75 (Very Good). The validation results of tringo-based Digital worksheets are declared to meet valid criteria by the validator with an average total validity of 4.0 (valid). The use of digital worksheets was responded positively by students at 80.4% and Lecturers of Natural Sciences III at 84.4%.

Abstract

The aim of this research is to develop Physics problems that are appropriate to be used for the final assessment at High School level with Rasch Model Analysis. Research method used in this study is Research and Development with the ADDIE model. Physics problems developed refers to the USBN blueprint issued by BSNP. Problems that have been developed will be validated by Physics experts, then tested on students, and analyzed for their quality using Rasch Model analysis. Validation results from Physics experts gave a score of 86.25% with very good criteria, it shows that Physics problems are feasible in terms of Physics material. The problems that have gone through the validation stage are then tested to several students and analyzed using the Rasch Model. Results of the analysis show that problems that have been developed have good validity and reliability. Problems that have been developed also have varying degrees of difficulty. Results of this analysis also show that problems that have been developed are not biased for a certain group. Based on the results, it can be concluded that Physics problems that have been developed are appropriate to be used for the final assessment at High School level.

Abstract

Science learning based on 2013 curriculum requires the students to be able at analyzing, evaluating, and creating to achieve higher order thinking skills (HOTS). The results of observation at SMP N 2 Sukolilo showed that there was no task or question which was specifically used to measure HOTS of the students. The aim of this study is to analyze the characteristics of two-tier multiple choice assessment instrument and HOTS ability of the students. This research was conducted by using Research and Development (R&D) method. Samples were taken by random sampling technique from the population of class IX students of SMP N 2 Sukolilo in the academic year 2019/2020, then class IX C was selected for small-scale trial, class IX B was selected for large-scale trial, and class IX A was selected for trial use. Data was taken by some methods such as test, questionnaire, and documentation. The characteristics of two-tier multiple choice assessment instrument was analyzed by expert judgment and empirical testing. Whereas, HOTS level of the students was analyzed using the HOTS Category Scale. The results of the analysis of the characteristics of two-tier multiple choice assessment instrument indicated that the developed instrument had fulfilled the requirement as a good instrument, namely (1) valid, with the result of expert validation as many as 79% (feasible) and the results of the item analysis was 0.49 (sufficient ); (2) reliable, with the reliability result was 0.40 (reliable); (3) relevant, representative, practical, and specific as indicated by the results of the teacher's questionnaire responses with the percentage 75% (good); (4) discriminatory power, with the average of analysis result was 0.36 (good); and (5) proportional / difficulty level, with the analysis result of most questions in the moderate category. Furthermore, the analysis results of HOTS level of the students showed that the students on the large-scale trial were mostly in the moderate category (67%) and some of them in a small portion were in the low category (33%). While, HOTS level of the students on the trial use showed that most of the students were in the moderate category (50%), some of them were in the low category (30%), and a small portion of them were in the high category (20%). The conclusion of this study is the developed two-tier multiple choice assessment instrument has been feasible, because it has met the requirements as a good instrument and can be used to measure HOTS of the students.

Abstract

This research aims to find out the influence of the application of the group investigation cooperative learning model on critical thinking skills and the scientific communication skills of students. True Experimental Design in the form of Posttest-Only Control Design is a research design applied to this research. Analysis of the data obtained showed that the correlation coefficient value of the critical thinking skills test data was r = 0.672. The results of the t-test analysis showed that t-count = 5.671 and t-table = 2.042, which means that there is an influence on the application of the cooperative learning type group investigation model in the experimental class as seen from the coefficient of determination (KD) of 33%. The value of the correlation coefficient in the analysis of students' scientific communication skills data is r = 0.9. The value obtained from the calculation of the t-test is t = 3,576 and t table = 3,182 which means that there is an influence on students' scientific communication skills after the implementation of the cooperative learning model group investigation type. The coefficient of determination of students' scientific communication skills is 81%. The conclusion that can be drawn from the research that has been carried out is that there is an influence on the ability to think critically and the scientific communication skills of students after the implementation of the cooperative learning model group investigation type in the learning process.
