Abstract

Abstrak: Penelitian dan pengembangan ini bertujuan untuk menghasilkan Lembar Kerja Siswa (LKS) berbasis inkuiri terbimbing untuk meningkatkan keterampilan proses sains siswa pada materi bidang miring dan tuas. Pengembangan yang digunakan mengacu pada model ADDIE (Analyze, Design, Development, Implementations, and Evaluation). Instrument pengumpulan data yang digunakan berupa pedoman wawancara, lembar validasi, dan angket uji keterbacaan. Hasil penelitian ini menunjukkan bahwa LKS yang dikembangkan memiliki kelayakan yang tinggi. Hal tersebut dapat dilihat pada tahap uji kevalidan LKS yang dinilai oleh tiga orang ahli meliputi ahli materi dan ahli media, diperoleh rata-rata penilaian sebesar 87,55% dari ahli materi dan 91,01% dari ahli media, sehingga penilaian ini membuktikan bahwa LKS memenuhi kriteria “sangat valid”. Pada tahap uji kepraktisan, respon siswa terhadap LKS diperoleh rata-rata skor sebesar 92%. Rata-rata penilaian siswa tersebut memenuhi kriteria “sangat baik”. Pada tahap berikutnya yaitu uji keefektifan dilihat dari hasil belajar siswa. Hasil rata-rata nilai pre-test adalah 50,75 kelas A dan 48,83 kelas B, sedangkan rata-rata nilai post-test adalah 80,67 kelas A dan 81,33 kelas B. Berdasarkan dari tahapan yang ditempuh dengan hasil yang diperoleh, menunjukkan bahwa LKS berbasis inkuiri terbimbing layak dan efektif dalam meningkatkan keterampilan proses sains siswa.Abstract:  This research and development aims to produce student worksheets (LKS) based on inquiry guided to improve student science process skills on slope and lever material. The development used refers to the model ADDIE (Analyze, Design, Development, Implementations, and Evaluation). The data collection instruments used are interview guidelines, validation sheets, and readability test polls. The results of this study showed that the developed LKS have high feasibility. This can be seen at the test phase of Kevaliand the LKS assessed by three experts covering materials and media experts, obtained an average assessment of 87.55% of the material experts and 91.01% of the media experts, so that this assessment proves that the LKS meet the criteria "very valid". At practicality test, the student response to the LKS was acquired on average score of 92%. The average student rating meets the "excellent" criteria. At the next stage is a test of the effectiveness seen in student learning outcomes. The average result of pre-test values is 50.75 Class A and 48.83 Class B, while the average post-test value is 80.67 Class A and 81.33 Class B. Based on the stage traveled with the results obtained, the LKS-based inquiry is guided to be worthy and effective in improving students ' science process skills

Abstract

The aim of this research is to develop an assessment instrument for problem-based Phase B science learning that is valid, practical and effective for measuring the critical and creative thinking abilities of students in elementary schools. This type of research is Research and Development (R&D), with development design referring to Borg & Gall theory. The population in this study was class IV students at SDN 4 Bumi Waras Bandar Lampung. Data collection tools use valid and reliable test instruments. The final average validation results from material experts, evaluation experts and language experts obtained a score of 87.75% with very valid criteria. The test results for the educator practitioners were 83% and the students were 82% with very practical criteria. The data analysis technique uses the One-Sample Z-Test to determine the correctness of the results of the assessment scores with a significance level of 95% (α 0.05), with a significance value of 0.023 obtained, indicating that the sig. value < 0.05 means H0 is rejected and H1 is accepted, so Effective assessment instrument for measuring students' critical and creative thinking abilities in elementary schools. Based on this research, it can be concluded that the assessment instruments for problem-based science learning are valid, practical and effective for measuring the critical and creative thinking abilities of students in elementary schools.

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
