In the era of the industrial revolution 4.0 and the pandemic era, innovation is needed in thedevelopment of technology-based evaluation tools. One of them is the ispring suite 9. Evaluation tool isimportant because it can help the process of evaluating educators to find out information on theachievement of results during the learning process. In addition to learning outcomes, evaluation can alsodetermine the ability of students to understand concepts. One of them is a two tier multiple choiceevaluation test. Two tier multiple choice is a form of two-tier multiple choice evaluation test. The purposeof this study is to develop a learning evaluation tool that can find out students' understanding of conceptsand can be used online. The research and development model used is 4D. The research instruments usedwere interview sheets, validation sheets, test instruments, and questionnaires. Data analysis techniquesused qualitative and quantitative. The result of this study is a two-tier multiple choice based mathematicsevaluation tool using ispring suite 9 which is seen from: (1) the percentage of validation results frommedia experts is 90.5% and material experts is 96.5%, both of which fall into the very feasible category.(2) the quality of the items seen from the validity obtained 8 valid items with a reliability of 0.815.Judging from the level of difficulty, the percentage is 10% difficult, 80% moderate and 10% easy, thedistinguishing power is obtained 5 questions are included in the good category, 3 questions are quitegood, 1 question is very good, and 1 question is bad, and the effectiveness of the distractor has 9distractors who selected > 5% of all students. (3) The percentage of students 'conceptual understandingafter evaluating two tier multiple choices is 50.5%, which is in the sufficient category, and the results ofthe students' responses are 82% which is included in the very interesting category.

The research was conducted with the aim of knowing mathematic learning with a realistic mathematics approach has an effect on the ability to understand students’ mathematical concepts better. Conducted using a quasi-experimental research type, the learning process applied involves two types of classes, namely the experimental class and the control class. PMR-based learning is used in the experimental class, while the control class is used for conventional learning. Considering that mathematics lessons cannot be separated from students' creative learning abilities, in addition to the posttest only control design in the form of a final test of understanding the concept of research instruments, such as learning creativity questionnaire sheets are also given to students. Using Statistical Product and Service Solutions (SPSS) data analysis techniques with a probability value (significant) of 5%, it shows a positive influence which means that H0 is rejected and H1 is accepted. Based on the descriptive data obtained, it is known that the mean posttest learning outcomes in the experimental class (PMR) are greater than the control class (conventional), which illustrates the application of learning using PMR has a significant influence on the ability to understand mathematical concepts and learning creativity of class VIII SMP Muhammadiyah 1 Babat.

This research was conducted to produce an ethnomathematics-based electronic student worksheet product (E-LKPD) using the anyflip application for rectangular and triangular material that obtained validity, practicality, and effectiveness so that it was suitable for use by students. The method used in this research is research and development using a four-D model consisting of define, design, development, and disseminate stages. To measure E-LKPD so that it is feasible to use, namely using interview test sheets for educators and students, expert validation sheets to measure product validity, student learning outcomes tests to measure product effectiveness, and student response questionnaires to measure product practicality. The results obtained in research and development are obtaining a percentage of validity of 95.7%, practicality of 82.88%, and effectiveness of 81.00%. Therefore, the development of E-LKPD based on ethnomathematics using the anyflip application has good and proper quality so that it can be used by class VII students as learning companions in the learning process.
