Development of Ethnomatematics-Based E-Book Teaching Materials to Train Numeracy Skills in Geometry Materials in Elementary Schools

/in /by

This study aims to develop ethnomathematics-based E-Book teaching materials to train students’ numeracy skills and to determine student learning activities when using E-Book teaching materials. This research is a type of Research and Development (R&D) research. The development model used in this study is the ASSURE development model. This research will later develop valid, practical and effective ethnomathematics-based E-Book teaching materials as well as analyze student learning activities. Data collection instruments in this study used validation sheets, questionnaires, tests and observation sheets. The data analysis technique used is the analysis of validity, practicality, effectiveness and analysis of student learning activities. The results showed that the validity of the media and material validity of E-Book teaching materials based on ethnomathematics obtained results of 93.7% and 89.2% with the “Very Valid” criteria. The practicality of ethnomathematics-based E-Book teaching materials obtained results of 94.2% from teacher responses and 82% from student responses so that ethnomathematics-based E-Book teaching materials can be said to be “Very Practical”. Furthermore, the effectiveness of E-Book teaching materials based on ethnomathematics obtained an average N-Gain result of 42.50% with the “Medium” effectiveness criterion. Meanwhile for the results of student learning activities, the results obtained in the experimental group were greater than in the control group, namely 87% with the criteria of “Very Active”.

Development of Quizz-Based Creative Thinking Skill Assessment in Thematic Learning of Elementary School Class V Students

/in /by

This research and development aims to develop Quizizz-based assessment instruments of creative thinking skills. This study applies the type of development research using the ADDIE model (Analysis Design-Develop-Implement-Evaluate). The Quizizz-based creative thinking skills assessment instrument was tested on a limited scale with 15 students from 3 different schools (SDN 1 Pasir Gintung, SDN 1 Kota Baru, and SDN 2 Kampung Baru). The improved instrument was tested on a large scale in 3 schools (SDN 1 Pasir Gintung, SDN 1 Kota Baru, and SDN 2 Kampung Baru). Data collection techniques using non-test in the form of questionnaires and interviews. Data analysis in this research is descriptive qualitative and quantitative analysis. (1) Qualitative descriptive analysis techniques are used to analyze data from experts and user validation results. (2) Quantitative analysis descriptive techniques are used to analyze the data obtained from the questionnaire scores. The results of this study indicate that research on the development of Quizizz-based creative thinking skills assessment instruments in thematic learning of fifth grade elementary school students is declared valid (suitable for use), the instrument questions are categorized as sensitive and practical.
