Developing E-Mowara: An archipelago-insighted electronic module to train middle school students\u27 computational thinking skills
Get PDFTo face the challenges of Indonesian education in the 21st century, the requirements for abilities are crucial, but the facts show that students are less able to use and adapt their abilities with insights aligned with the identity of the Indonesian nation. For this reason, researchers developed an E-Mowara: Interactive Emodule with an Archipelagic Outlook. This study aimed to develop the E-Mowara electronic module and find out students\u27 responses after using the developed media. The target of this study was class VIII junior high school students with number pattern material. This development research uses a design research type of development study. The data collection technique in this study used a questionnaire with data processing techniques analyzed using percentage data analysis techniques. This is based on the validation results in terms of the material average of 84.35% with the appropriate criteria, and in terms of media, an average of 85.90% with the appropriate criteria. Students\u27 responses to E-Mowara were quite good, with a percentage of 92.5%. Based on this result, the E-Mowara Electronic Module is known as valid, easy to use, and effective in developing computational thinking skills with insights that are in harmony with the identity of the Indonesian nation

Exploration of high school students\u27 sentiments and emotions towards mathematics: Linked to learning outcomes
Get PDFMathematics research often focuses only on students\u27 learning outcomes without considering their emotional aspects. This study aims to describe the tendency of students\u27 sentiment toward mathematics in general and partially based on mathematics learning outcome groups, namely high, medium, and low. In addition, a mood analysis was conducted using Ekman\u27s Basic Emotion classification. Data collection techniques are questionnaires and documentation. The questionnaire contains open questions about students\u27 opinions on mathematics and closed to queries for student demographics. Documentation is done by collecting test scores from student grade books. This study used a descriptive method with data in the form of 72 comments from grade XI high school students in Bandung City, which were analyzed using the Orange Application Sentiment Analysis. The results of the study showed that (1) student sentiment was generally dominated by positive sentiment at 72.22%, (2) positive sentiment also dominated the groups of students with high, medium, and low learning outcomes, with a percentage of more than 68%, and (3) the results of the classification of emotions based on Ekman\u27s Basic Emotion indicated that "joy" was the most dominant emotion, while "anger" had the lowest frequency of occurrence. This study provides new insights regarding students\u27 emotional aspects in mathematics learning, which can be used to improve teaching strategies

Get PDFThis research is qualitative research with design research methods and a development research type aiming to produce valid and practical worksheets on relational and functional materials based on problem-based learning (PBL) to support students\u27 conceptual understanding. The learning process is carried out in the classroom with learning activities, accompanied by a student\u27s worksheet, which consists of 2 questions. The subjects of this study were students of class VIII 10 of SMP Negeri 8 Palembang, with 6 students as the focus of the research. There are 2 stages in this research, namely: (1) preliminary stage and (2) prototyping stage (formative evaluation), which is divided into 5 stages, namely (1) self-evaluation, (2) expert review, (3) one to one, (4) small group and (5) field test. This research was conducted based on the learning system in schools with data collection techniques, namely walkthroughs, tests, interviews, and questionnaires, to be collected and analyzed qualitatively to see the validity and practicality of the worksheet. The results of this study will show that the worksheet that has been made is valid, as seen from the results of the expert review and practical validation sheets obtained from the questionnaire results, with an average of 84.03%, which is included in the valid and practical categories. The developed worksheet also supports understanding PBL-based concepts (Problem-Based Learning) in solving problems given in relation and function material, which can be seen from the overall student test results
Statistics education research integrated with Islamic studies (A study of validity and practicality of textbook development)
Get PDFThis research is based on the need for a textbook of educational research statistics that is suitable for use, while its availability has not been met. Therefore, this research is a development study with ADDIE design (analysis, design, development, implementation, and evaluation), which aims to develop and produce an Islamic integrated educational research statistics textbook that meets valid and practical criteria. The data in this study were collected using questionnaire techniques and validity and practicality questionnaire instruments. Development is first carried out before these two instruments are used to ensure their feasibility. The data that has been obtained is analyzed using the Aiken index formula related to the calculation of validity and percentage related to practicality. The results of this study can be summarized in two conclusions. First, the Islamic integrated educational research statistics textbook is at the "very valid" validity level. The Aiken index score is 0.9215. Second, the Islamic integrated educational research statistics textbook based on mathematical communication skills is at the "practical" level of practicality. The numerical validity value is 77.66%. The implication of the results of this study is the production of a textbook that is suitable for use and tested for its effectiveness in learning educational research statistics
