Abstract

The credibility analysis of the microteaching assessment instrument based on the responses of biology education students using the Rasch model. This study aims to reveal the credibility of the microteaching (MT) assessment instrument by analyzing the responses of biology education students using the Rasch model. The biology education students as participants played roles as assessors and practitioners of MT. The instrument used was the Instrument of Assessing the Learning Implementation (IPPP) in Book 4 of the 2013 In-Service Teacher Training Program (PLPG) Guidelines issued by the Human Resources Development Agency (BPSDM) of the Ministry of Education and Culture. The data obtained were analyzed by multirater analysis of Many-Facet Rasch Measurement (MFRM) version 3.83.2. Based on the results and discussion, this study concluded that the MT assessment instrument in biology education using IPPP was quite credible, which was revealed from the following three points: 1) The responses of students practicing MT are based on the results of peer ratings on a logit scale ranging from -0.82 to 0.80, which means that students practicing were quite diverse and can be distinguished by the instruments; 2) Student responses as assessor to the MT assessment instrument in logit scale units ranged -1.99 to 0.94 which means that as an assessor, student were able to assess diversely. The student as assessor was also able to understand the different rating scales used; and 3) The results of the calibration of the instruments showed that 24 instrument items can provide accurate information about the performance of the practitioner with logit values ranged from a scale of -0.72 to 0.66.

Abstract

Module design for students laboratory activities plays an important role in the effective implementation of scientific investigation in the laboratory. The purpose of this review is to examine the types, topics, competencies, and approaches to develop laboratory module for biology students. The review of the literature was conducted systematically. Eighteen research articles were selected from 41 articles published within 2009 and 2019. The systematic review followed 5 steps. The research articles were searched using Google Scholar's online database and then traced back from the relevant international and national journals. The articles collected were selected by two reviewers who rated the quality. The results of the analysis showed that the laboratory modules are designed using the following basis: online, research, quantitative skills, inquiry, and traditional. The biology topics focused are Genetics, Ecology, Phylogenetics, Biochemistry, Molecular Biology, Evolution, Biotechnology, and Tissue Culture. The methods used for laboratory module development by Indonesian researchers are 4D, ADDIE, R & D, Dick & Carey, and Borg & Gall, while international researchers generally do not specify the name of the method used. Generally, the need analysis which focuses on the novelty of the developed concept is conducted in the beginning. It continues with module designing, validation, implementation, and response survey from the students as the module users.

Abstract

Evaluasi merupakan kegiatan, untuk melihat sejauh mana keberhasilan pembelajaran telah dilaksanakan. Kegiatan evaluasi memerlukan alat sebagai pengumpul data yang disebut instrumen. Sebuah instrumen dikatakan baik apabila memenuhi beberapa kriteria. Salah satunyadengan melakukan analisis butir soal. Penelitian ini bertujuan untuk mengetahui validitas, reliabilitas, tingkat kesukaran, dan daya pembeda soal pada  insrumen diagnostic materi virus. Responden penelitian berjumlah 346 siswa kelas X, XI, dan XII SMA Negeri dan Swasta di Kota Magelang. Instrumen yang diberikan berupa Assessment Diagnostic pada materi virus, yang terdiri dari soal Kolom Bukti Fakta (KBF), essay, dan Structure Communication Grid (SCG). Penelitian ini merupakan penelitian kuantitatif untuk mengetahui kualitas instrumen. Hasil penelitian menunjukkan persentase validitas soal KBF dan SCG 63,2% , soal essay 100%, semua soal reliabel, tingkat kesukaran soal mudah KBF dan SCG 38,6%, soal sedang 37,1%, dan 24,3% soal sukar. Sedangkan kesukaran soal essay 20% pada kategori mudah dan 80% pada kategori sedang. Daya pembeda soal  KBF dan SCG sebesar 62,2% kategori jelek, 31,5% kategori cukup, 6,3% kategori baik. Daya pembeda soal essay 60% soal pada kategori cukup dan 40% soal kategori baik. Berdasarkan hasil analisis, dilakukan perbaikan butir soal. Instrumen pada materi virus yang sedang dikembangkan, merupakan yang pertama di Indonesia.Quality analysis of item in the Assessment Diagnostic instrumen to detect misconceptions in high school students on virus material. Evaluation is an activity to see the extent to which the success of  learning has been carried out. Evaluation activities require tools as data collectors called instrumens. An instrumenis good, if it meets several criteria. One of them is by analyzing questions item. This study was aimed to determine the validity, reliability, level of difficulty, and differentiation of problems in the diagnostic instrumens of virus material. Respondents in this study are 346 students of class X, XI, XII of public and private High Schools in Magelang City. The instrumen provided is in the form of a Diagnostic Assessmenton virus material, which consists of the Facts Proof Column (KBF), essay and Structure Communication Grid (SCG). This research is a quantitative studywhich determine the quality of the instrumen. The results showed the percentageof the validity of KBF and SCG questions was 63,2%, essay questionswere 100%, all questions are reliable, the level of difficulty of easy questions of KBF and SCG is 38,6%, moderate questions are 37,1%, and 24,3% are difficult questions. While the difficulty of the essay is 20% in the easy category and 80% in the medium category.The differentiation of the KBF and SCG questions is 62,2% in the bad category, 31,5% in the sufficient category, 6,3% in the good category. The differentiation of essay questions 60% in adequate category and 40% in good categories. Based on the analysis, further improvements were made to the items. Instrumens in the virus material which are being developed are the first in Indonesia.
