Abstract: The Effectiveness of PLGI Model to Increase Students’ SPS in Hydrolyzing Salt Topics. This study aims to describe the effectiveness of the PLGI (Peer-Led Guided Inquiry) model to increase students' SPS (Science Process Skills) in hydrolyzing salt topics. The research used a quasi-experiment with Pretest Postest Control Group Design, purposive sampling technique was used in determining the samples, thus XI MIPA 1 was chosen as an experimental class and XI MIPA 2 was a control class. The data analysis technique uses non-parametric statistical tests, the Mann-Whitney U test. The effectiveness of the PLGI model for increasing SPS is shown by the significant difference in n-gain between the control and experimental classes. The results showed that the mean n-gain of the experimental class SPS and control class differed significantly from the Asymp value. Sig (2-tailed) 0.05 which is equal to 0.01, so it can be concluded that the PLGI model is effective in increasing students’ SPS.Keywords: Hydrolyzing salt, SPS, PLGI model. Penelitian ini bertujuan untuk mendeskripsikan efektivitas model PLGI (Peer Led Guided Inquiry) untuk meningkatkan KPS (Keterampilan Proses Sains) siswa pada materi garam menghidrolisis.  Metode dalam penelitian ini yaitu quasi experiment dengan Pretest Postest Control Group Design, pengambilan sampel dipilih dengan teknik purposive sampling, didapatkan kelas kelas XI MIPA 1 sebagai kelas eksperimen dan XI MIPA 2 sebagai kelas kontrol. Teknik analisis data menggunakan uji statistik non parametik, yaitu uji Mann-Withney U. Efektivitas model PLGI untuk meningkatkan KPS ditunjukkan dari perbedaan rata-rata n-gain yang signifikan antara kelas kontrol dan eksperimen. Hasil penelitian menunjukkan bahwa rata-rata n-gain KPS kelas eksperimen dan kelas kontrol berbeda secara signifikan dilihat dari nilai Asymp. Sig (2-tailed) 0,05 yaitu sebesar 0,01, sehingga dapat disimpulkan bahwa model PLGI efektif dalam meningkatkan KPS siswa.Kata kunci: Garam menghidrolisis, KPS, model PLGI.http://dx.doi.org/10.23960/jppk.v8.i2.201905

The making of questions is part of the assessment which aims to measure the minimum competency of the achievements obtained by students after accomplishing the learning. The application of High Order Thinking Skills (HOTs) assessments forms the basis of an assessment with the ability in the cognitive domain to analyze, synthesize and evaluate. The purpose of this activity was to provide guidance to lecturers through technical guidance is to improve the professional competence of Tanjung Karang State Polytechnic Lecturers regarding conventional and authentic assessment forms based on High Order Thingking Skills. The technical guidance method used in this activity are applying contextual strategies, namely linking theory with practice delivered with guided practice methods, namely teaching systems oriented to solving problems faced by lecturers of Medical Laboratory Technology Study Program, Applied Bachelor Program as many as 20 people. The bimtek activity provided insight and increased understanding of lecturers regarding the compilation of the grid and analysis of HOTs questions.The results of the activity showed that there was an increase in the understanding of positive-valued participants that had increased with an average N-gain score of 79 (high category). The main study of coaching material that has the lowest level of understanding is to make a grid of questions with cognitive levels C4, C5 and C6. Therefore, the technical guidance activities are categorized as good by successfully increasing participants' overall understanding both in theory and work practice.Keywords: HOTs; pedagogical competence; problem development; assessment.

Abstract

The Argument-Driven Inquiry (ADI) learning model, which is considered appropriate for use in higher education, is still not able to overcome students' difficulties in developing argumentative discourse so that their understanding of concepts tends to be low. The management of the learning process for students with different academic abilities requires scaffolding in the ADI model which is implemented gradually from the class, group, and individual levels. This research has produced an Argument-Driven with Scaffolding (ADIS) model which is a modification of the ADI model with the addition of standpoints and phasing. Standpoint as a statement of claim functions in generating arguments through debate. Meanwhile, the phases consisting of initiation, development, and reinforcement function in the development of individual argumentation skills. This study aims to compare the understanding of the concept of students with different academic abilities by using ADI, ADIS, and conventional learning models. The design of a non-equivalent pre-test-post-test control group was used on 180 prospective science teacher students at the University of Lampung. The concept comprehension test is used to measure students' ability to understand the concepts taught from answers in the form of essays. The test questions relate to the level of thinking from Bloom's cognitive domain, namely remembering, understanding, applying, analyzing, evaluating, and creating. The results of the analysis of students' concept understanding data using ANCOVA showed that the achievement of concept understanding with the ADIS learning model was equivalent to ADI but higher than the conventional model. Students with high academic ability have a higher understanding of concepts compared to students with low academic ability. The highest average concept understanding was achieved by students with high academic ability in the ADIS class, while the lowest average was achieved by students with low academic ability in the Conventional class. The ADIS model has been proven to be able to train students' skills in drafting high-quality arguments and participating productively in scientific arguments in stages so as to improve understanding of concepts. Standpoint as a starting point in argumentation development and phasing (initiation, development, and reinforcement) in the ADIS model is effectively used as a scaffolding for students to develop argumentation skills both classically, in groups, and individually.       Keywords: academic ability, argument-driven inquiry, conceptual understanding, scaffolding.DOI: http://dx.doi.org/10.23960/jpmipa/v25i3.pp1224-1243
