Kurikulum merdeka menuntut peran guru untuk mengimplementasikan pembelajaran yang berdiferensiasi. Pembelajaran berdiferensiasi dapat dilakukan dengan 4 cara, salah satunya adalah dengan diferensiasi konten. Diferensiasi konten dapat dilakukan dengan menyesuaikan bagaimana materi akan diajarkan atau dipelajari siswa berdasarkan gaya belajarnya. Untuk melakukannya, guru dapat menyajikan media pembelajaran interaktif yang mengakomodasi gaya belajar siswa. Untuk menyajikan media pembelajaran tersebut diperlukan bantuan teknologi yang memadai, seperti iSpring. Penelitian ini bertujuan untuk mengembangkan media pembelajaran yang mengakomodasi gaya belajar siswa untuk menunjang pembelajaran berdiferensiasi pada materi perbandingan trigonometri dengan menggunakan iSpring. Metode penelitian yang digunakan adalah metode R&D dengan model pengembangan ADDIE. Uji coba peneltian pengembangan ini dilakukan di kelas X RPL 2 SMKN 4 Banjarmasin, yang terdiri dari 36 siswa dengan dominan gaya belajar visual dan audiotori. Dari hasil penelitian didapatkan bahwa media pembelajaran yang dikembangkan telah dikategorikan valid dan sangat praktis untuk siswa visual dan siswa audiotori.

The objective of this study is to determine whether a problem-based learning approach has an impact on the critical thinking ability of students of grade VII in the 1^st Grade State High School in relation to the form of numbers. At SMPN 1 Pangkatan, which is located in the village of Padang Village Education, this research was carried out. The study used basic random sampling techniques to gather data, and found that classes VII-2 were taught using a problem-based learning model, while classes VII-3, which consisted of 26 students, were teaching using a live learning model. The essay-based examination of this student’s critical thinking abilities uses the pre-test dan post-test control group design. In addition, normality, homogeneity, hypothesis and descriptive data analysis are used in data analysis techniques. The average of the experimental class after the test was 86,27, while the middle of the control class was 76,15. This shows that the average score for both classes have higher critical thinking abilities than students in control classes.

This research aims to determine the need for Student Worksheets (LKPD) and to determine student responses regarding the development of electronic-based LKPD, and is based on the many benefits that digital teaching materials in the form of E-LKPD have compared to LKPD. The subjects in this research were 18 grade 1 students of Yadika Jambi Vocational School for the 2023/2024 academic year and one mathematics teacher at the school. Data collection for this qualitative research was carried out in two ways, namely giving response questionnaires to 18 students to obtain responses regarding the need for worksheets and interviews for one teacher as supporting descriptive data to compare whether the assessments carried out on teaching materials were in accordance with the student's answer questionnaire. The results of the analysis show that students' responses to the development of E-LKPD are considered quite good. The implementation of E-LKPD has not been implemented in this school and the learning process is still conventional. Apart from that, students think that the development of E-LKPD is interesting and educational. Therefore, the data from this needs analysis is used as a preliminary study to develop an E-LKPD that can be used.

Hela Azzahra, Putri Yuanita, Armis Armis — Sel, 30 Apr 2024 19:11:14 +0000

Mathematical representation is one of the mathematical abilities that students must have in learning mathematics. However, based on interviews and initial tests, it is known that students’ mathematical representation ability is low so that learning designs are needed that can facilitate these abilities. The development of teaching modules based on Problem Based Learning on the content of data distribution measures for phase E students with valid and practical criteria is the purpose of this research. The teaching module is accompanied by LKPD and assessments consisting of diagnostic assessments, formative assessments and summative assessments. This research is development research (R&D) with the 4D model. The instruments used were validation sheets and learner response questionnaires. Validation of the teaching module was carried out by three validators and then revised according to the suggestions of the validators. One to one evaluation was carried out after the student worksheet (LKPD) was declared to meet valid criteria after validation. After that, small group trials and field tests were conducted to see the practicality of the teaching module. Based on the validation results, the average value for each teaching module is obtained in a very valid category. Based on the results of small group trials and field tests, the teaching modules have met the practicality requirements.

The purpose of this study is to explain the application of learning, student activities, and assess the effectiveness of the AIR model in improving students' mathematical spatial abilities. This study is quantitative descriptive with One-Group Pretest-Posttest design. The subject is class VIII-D UPT SMPN 10 Gresik. Observation sheets and pretest-posttest are research instruments. The material tested is to build a room with a test consisting of 3 different description questions. Data were analyzed with T test and Gain test using SPSS version 22. The results showed that the implementation of learning that took place during the two meetings was categorized very well with the same value of 3.74 or 93.5%. Student activities are categorized as active, with scores of 64.27% and 65.32%. The average score of students' mathematical spatial ability increased from 32.7645 to 61.7087. The paired sample t-test results obtained a significance of 0.000<0.05, so its H_0 accepted. The result of the gain test was normalized at 0.4305 where the increase in students' mathematical spatial ability was categorized as moderate. So, the AIR learning model is said to be effective in improving students' mathematical spatial abilities. Thus, the AIR learning model can be used to support students' mathematical spatial abilities.
