    Most of the evaluation tools available in high schools still prioritize mathematical analysis, and give less attention to the students. As a result, it causes mathematics anxiety among students. A multi-representation based four-tier multiple choice test can help students with mathematics anxiety to use other representational abilities, such as pictures, verbal, graphs and tables.The research objective was to develop an evaluation tool that was used to determine the characteristics of the instrument, the quality of the instrument, and to measure the multirepresentasis abilities of students on simple harmonic motion material. This research was a Research and Development (R & D) type. Sampling was carried out at three SMAN 1 in Tegal Regency, with a total of 315 students as respondents. The four-tier multiple choice test consists of 27 items covering four representations, namely mathematics, tables, verbal and pictures/graphics. The average result of validity by experts is 86.21% with very good category. The reliability value in the field test were 0.890 at SMAN 1 ); 0.885 at SMAN 1 Q; and 0.887 at SMAN 1 R. The distinguishing power test showed that 74.08% of the items were accepted (SMAN 1 P); 59.26% of questions were accepted (SMAN 1 Q); and 66.67% of the questions were accepted (SMAN 1 R). The difficulty level of the questions shows that 14.81% of the questions are difficult; 66.67% medium questions; and 18.52% easy questions. If the questions used table representations, 52.44% of students were able to convert them to graphs. Meanwhile questions with verbal representations found that most students were able to convert them to tables (52.85%). However, for questions with image representations, most students were able to convert them to verbal with 53.23% and questions with mathematical representations, so most students were able to convert them to verbal, with 49.84%

    Assessing the habits of mind among prospective teachers is an essential part of learning. Therefore, this research aims to develop the habits of mind instrument in the context of basic physics practicum. It was conducted using the research and development method which has three stages namely (1) planning the test, (2) implementing the test, and (3) determining the validity and reliability. The sample consisted of 105 biology teacher candidates taking basic physics courses. The habits of mind instrument developed was in the form of a questionnaire consisting of 52 items and is related to basic physics practicum. Furthermore, exploratory factor analysis and the Rasch model approach were used in developing the instrument. Based on expert judgment using Fleiss Kappa, the content validity was 0.700 and was classified in the good category. The developed instrument was considered reliable based on Cronbach’s alpha value of 0.970. The exploratory factor analysis reduced the dimensions of the instrument to 11 factors. The analysis of the Rasch model met the element of unidimensionality. There is no bias on the instrument based on gender and place of residence. However, efforts are needed to overcome the lack of creative thinking habits among prospective biology teachers

    The research aims to develop adaptive electronic modules using Moodle-based blended learning as a solution to improve representation skills in the school environment. This research combines online and face-to-face learning methods (blended learning) with the use of Moodle as a digital learning platform. Three forms of representation in the concept of physics, are (1) verbal representation; (2) visual representation; and (3) mathematical representation. The formulation of the problem in this research is the characteristics, validity, and effectiveness of the E-module. This module aims to provide learning content that is tailored to the needs and abilities of each individual student. Adaptive features allow students to access materials, assignments, and learning resources appropriate to their skills level. Learning is done through a combination of classroom teaching and e-modules through Moodle. E-module development model uses the research and development method. The research design used is a true experimental design in the form of a "Posttest-Only Control Design". Assessment includes data collection through surveys, observation, and evaluation of learning outcomes. The purpose of the evaluation is to analyze the effectiveness and efficiency of using adaptive e-modules with Moodle based on blended learning to improve students' representation skills at school. The research results showed that the E-module assessment by experts obtained a content percentage and eligibility criteria of 91.7% (feasible). To determine the level of effectiveness through the t test and comparison of posttest results. This is evidenced by the test using SPSS version 23 which shows a significance value of 0.00 <0.05. In visual representation, a percentage of 87.5% was obtained in a very good category, for mathematical representation, a percentage also was obtained in a very good category, 88.5%, and in verbal representation, a percentage was obtained in a category of 90%, as the greatest. With an average post-test score of 88.8 for the experimental of the class and 74.2 for the control of the class. Adaptive e-modules through Moodle-based blended learning can be an effective choice for increasing representational abilities and facilitating personalized and flexible learning. The results of this study are expected to encourage the development of adaptive learning systems in schools and support the improvement of student learning outcomes
