Abstract

The demands of the 21st century, students must have a high understanding of concepts. This study aims to develop a HOT-based two-tier multiple choice diagnostic test instrument to determine the profile of students' understanding of concepts analyzed using the Rasch model. The research method used is research and development. The design of this study uses the 4D model. The subjects in this study were students of class X SMAN 1 Bae Kudus. Data collection techniques are done by observation, documentation, tests, and questionnaires. Data analysis uses classical model analysis and Rasch model. In the classical model analysis, analysis of validity, reliability, difference power, and item difficulty level was carried out, while the Rasch model analysis carried out reliability analysis, item fit, wright map, item measure, person fit, person measure and DIF items. The test instrument in this study tested the reliability and validity of the contents, constructs and items. Profile understanding of students' concepts with the criteria of understanding concepts by 55%, positive misconceptions by 10%, negative misconceptions by 17%, and not understanding concepts by 18%. Both students and teachers gave positive responses to test instrument. As many as 97% of students gave positive responses to the developed test instruments.

Abstract

The 2013 scientific-based curriculum, teachers must facilitate students to gain knowledge or skills based on the scientific method. The research aims to analyze the effectiveness of teaching materials. This type of research development, teaching materials have valid content and media. Teaching materials are declared effective if there is an increase in students' classical mastery, an increase in the achievement of basic competencies, and students can understand macroscopic, microscopic and symbolic level representations. Quantitative descriptive research method, starting from the analysis of the quality of teaching materials and diagnostic test instruments Two Tier Multiple Choice (TTMC), application of teaching materials, application of questions, data analysis of test results, classical completeness, achievement of basic competencies, and analysis of representational understanding. The research subjects were students of class XI and XII MIPA. The results of the study were obtained from the results of the student's TTMC test on the buffer solution material that had used Teaching Materials. Data analysis was done classically. The results showed that there was an increase in classical completeness by 9%, the achievement of basic competence indicators increased by 8% and concept understanding increased by 6%. So that the teaching materials developed are effective to use.

APPLICATION OF THE RASCH MODEL ON THE TEST INSTRUMENT TO ANALYZE THE PROBLEM-SOLVING ABILITY OF STUDENTS IN ACID-BASE SOLUTIONS MATERIALSAbstractIn 21st century education, students are required to have high problem-solving skills. This study aims to reveal the quality of the test instrument with the Rasch model. Descriptive quantitative research is used with total of 38 students of class XI SMAN 2 Semarang became the subjects in this study. The data obtained in this study is from a combination of student response patterns on the product development diagnostic test instrument. The data analysis used was IRT Rasch. Rasch model analysis for summary statistics, item-fit, wright-map, item-measure, person-measure, person-fit dan item-DIF. The value of person reliability is 0.78(sufficient), and item reliability value is 0.8(good). Cronbach's alpha value is 0.82 (very good). Based on the analysis Rasch model, it was found that there were two students (12P and 37P) whose response patterns were not ideal. The results showed problem-solving ability profile of students in the very high category of 26%, high of 29%, average of 16%, low of 13%, and very low of 16%. The results of this study indicate that the test instrument can be used for further research in measuring student problem solving and the Rasch model contributes to teachers and schools in identifying students' abilities in more detail. AbstrakPada pendidikan abad-21, siswa dituntut harus memiliki keterampilan problem-solving yang tinggi. Penilaian keterampilan problem-solving dapat dilakukan secara online yang terintegrasi pada soal tes pengetahuan. Penelitian ini bertujuan untuk mengungkap kualitas instrumen tes dengan model Rasch. Penelitian kuantitatif deskriptif digunakan dalam penelitian ini. Total 38 siswa kelas XI SMAN 2 Semarang menjadi subjek dalam penelitian ini. Data yang diperoleh dalam penelitian ini adalah dari kombinasi pola respon jawaban siswa pada instrumen tes diagnostik produk pengembangan. Analisis data yang digunakan menggunakan Item Response Theory (IRT) model Rasch. Analisis model Rasch untuk summary statistics, item-fit, wright-map, item-measure, person-measure, person-fit dan item-DIF. Nilai person reliability didapatkan sebesar 0,78, kriteria cukup, dan nilai item reliability sebesar 0,85, kriteria bagus. Nilai alpha Cronbach sebesar 0,82, kriteria bagus sekali. Berdasarkan hasil analisis Rasch model ditemukan ada dua siswa yang pola responnya tidak ideal yaitu siswa 12P dan 37P. Hasil penelitian menunjukkan profil kemampuan problem-solving siswa dengan kategori sangat tinggi sebesar 26%, tinggi sebesar 29%, rata-rata sebesar 16%, rendah sebesar 13%, dan sangat rendah sebesar 16%. Hasil penelitian ini menunjukkan bahwa instrumen tes dapat digunakan untuk penelitian lanjutan dalam mengukur pemecahan masalah siswa dan model Rasch memberikan kontribusi kepada guru dan sekolah dalam mengidentifikasi kemampuan siswa lebih rinci

Abstract

The Covid-19 pandemic has given a new nuance to the world of education, learning which is usually done face-to-face has become based on digital technology. However, online learning has an unfavorable effect in improving students' literacy and numeracy skills. Both abilities are needed by students to be able to solve problems well. The purpose of this study was to develop a two-tier multiple choice complex test, Minimum Competency Assessment type, including digital-based literacy and numeracy indicators, for analyzing problem-solving students’ level 11 in reaction rate topic. This research is an R&D research with ADDIE model. The test subjects 54 students of class XI High School 1 Welahan. The instrument has been tested for content validity, construct, and reliability. Content validity tested by six expert validators, with a score of 40.83 out of a total of 44, very valid. The construct validity, and reliability were tested using Rasch model analysis. The results show, from the 20 items developed, there are 3 items that are not valid, namely number 13, 12 and 19. The reliability test showed very good results, with index value of 0.91. Digital-based test instruments are considered more practical than paper-based tests, because they make it easier to assess and provide feedback. The results of the practicality test obtained as many as 92% (50 of 54) students gave a positive response. The existence of this test instrument makes it easier for teachers to train students' problem-solving processes and analyze problem-solving abilities more quickly through the analysis of the Rasch.

Abstract

The application of the contextual Problem-Based Learning (PBL) model is considered to enhance students' conceptual understanding of redox reactions and voltaic cells. In the context of the 21st century, which demands critical thinking, collaboration, and creativity, a learning approach that connects theory with real-life situations is crucial for developing these skills. This study aims to optimize the effectiveness of the contextual-based PBL model in enhancing students' conceptual understanding. The method used is reflective classroom action research (CAR), with two cycles based on the stages of Kemmis and McTaggart, utilizing assessment results and learning observations. The research results show a significant improvement in students' conceptual understanding. The average student score increased from 59.03 in the pre-cycle to 81.14 in cycle 1, and 88.81 in cycle 2. In addition, the percentage of student mastery also increased, from 41.67% in the pre-cycle to 66.67% in cycle 1, and reached 83.33% in cycle 2. This improvement demonstrates the effectiveness of implementing the contextual-based PBL model in enhancing students' conceptual understanding, particularly on complex materials such as redox reactions and voltaic cells.
