Abstract

Penelitian ini menghasilkan Lembar Kerja Peserta Didik (LKPD) Matematika bermuatan HOTS. Proses pengembangan LKPD ini menggunakan model-4D yang dikemukakan oleh Thiagarajan yang terdiri dari 4 tahap yaitu pendefinisian, desain, pengembangan, dan uji produk. Subyek yang digunakan adalah siswa kelas VIIISMPNegeri 2 Karanglewas.Teknik pengumpulan data meliputi angket hasil validasi dan kepraktisan. Analisis data yang dipakai meliputi data kualitatif dan kuantitatif. Hasil uji validasi LKPD dari ketiga validator diperoleh skor rata-rata 3,13 yang menunjukkan LKPD valid. Hasil uji kepraktisan LKPD diperoleh rata-rata 3,01 yang berarti praktis. Dengan demikian, LKPD berbasis HOTS materi Himpunan valid dan praktis serta dapat digunakan dalam kegiatan pembelajaran.  Abstract This research produce Mathematics Student Worksheets containing High Order Thinking Skills (HOTS). The process of Student Worksheets development was conducted using the 4D model proposed by Thiagaradjan consisted of 4 stages, namely the stage of define, design, develop, and disseminate. The subjects used were grade VIII students of SMP Negeri 2 Karanglewas. The data technique used was a questionnaire of validation results and practicality. The data analysis used includes qualitative and quantitative data. The Student Worksheets validation test results from the three validators obtained an average score of 3.13 which indicates a valid. LKPD practicality test results obtained an average of 3.01 which means practical. Thus, the student worksheets based HOTS of set material is valid and practical and can be used in learning activities.

Abstract

The study aims to find out pseudo-thinking in solving mathematical problems. The methods used in this study are qualitative descriptive. The research subject is junior high school students using the purposive sampling technique, the students are grouped into three ranks i.e. low, medium and high rankings which each ranked 3 students as respondents. The total number of respondents was 9 students. Data collection techniques using tests, interviews, and documentation. From the results of the study gained that: 1) students who are ranked low in solving mathematical problems are experiencing pseudo-analytic or pseudo-false, 2) students who are in the moderate level also experience pseudo-analytic or pseudo-incorrect, 3) students who are in high ranking experience pseudo-analytic and pseudo-4) students who experience pseudo-thinking choose procedures using their own reasoning and convince it as a correct understanding , so there is no attempt to re-examine what he has done

Abstract

This research aims to find out the description of Mathematic Combinatory Thiking Ability of the Students. This is a descriptive qualitative research. The subject of the research was the students of Grade XI.MIA-5 SMAN 5 Purwokerto. The technique of the data collection in this research was by test, interview and documentation. The result of the students’ mathematic combinatory thinking ability was grouped in 3, namely the high, middle, and low. Each group was taken 3 as the respodents. The result of the research showed that mathematic combinatory thinking ability of the high could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly, and able to solve more than one combinatory problem in one single mechanism. The students’ mathematic combinatory thinking ability of the middle could understand the problem faced and started to find the possibility of answering the correct answer, find all possible answers correctly. Then, the students’ mathematic combinatory thinking ability of the low could only understand the problem faced and started to find the possibility of answering the correct answer.

This type of research is qualitative research. The sample of this study was six students from class VIII B who were selected using a purposive sampling method. Data collection techniques are questionnaires, refractive thinking tests, interviews, and documentation. Data analysis techniques are divided into three stages: data reduction, data presentation, and conclusion. The results of this study indicate that students with the thinking personality type can gather information on the problem, link information in the issue with prior knowledge, propose solutions or alternative solutions to problems, eliminate solutions or alternative solutions to issues, carry out appropriate solving strategies and re-examine the solutions that have been obtained. Feeling personality type, students can gather information on the problem, relate the information in the issue with previous knowledge, and propose solutions or alternative solutions to problems
