Abstract

AbstrakSetelah lima angka tahun berjalan semenjak tahun 2016, prodi tadris IPA hanya memiliki laboratorium biologi dasar dan kimia dasar., amun belum memiliki laboratorium fisika dasar. Tentu hal ini sangat padahal pembelajaran fisika sangat terkait dengan adanya kegiatan praktikum di laboratorium. Pengadaan laboratorium yang memiliki prosedur panjang dan lama menjadi penghambat pembelajaran fisika. Phet menyediakan banyak simulasi pembelajaran dan dapat digunakan sebagai laboratorium virtual namun tidak memiliki petunjuk penggunaannya. Tujuan penelitian ini adalah untuk mengembangkan petunjuk praktikum berbasis laboratorium virtual pet pada pembelajaran fisika dasar di tadris IPA . Jenis penelitian ialah menggunakan jenis penelitian pengembangan tipe ADDIE,  produk yang dikembangkan divalidasi dengan oleh ahli materi ahli, ahli media, ahli bahasa , dosen yang mengajar lalu direvisi sesuai dengan saran kemudian diujicobakan ke lapangan dan dihitung besarnya respon peserta didik dengan menggunakan angket. Hasil yang diperoleh adalah sebagai berikut : bahwa hasil uji kelayakan mendapatkan penilaian dari ahli materi Fisika dasar 1 mendapat penilaian sebesar 85%, dari ahli materi Fisika dasar, ahli bahasa mendapatkan penilaian sebesar 80%, dari ahli media mendapat penilaian sebesar 78%, dari, sedangkan dari penilaian dosen  adalah sebesar 88%. Sehingga ketika semua validator ahli dan dosen  dijumlakan dan kemudian dirata- rata mendapatkan presentase sebesar 86,2%. Itu artinya adalah bahwa buku petunjuk praktikum yang telah dikembangkan sudah masuk dalam kriteria valid dan sangat layak sehingga dapat digunakan pada uji selanjutnya. Saat uji lapangan skala kecil, tanggapan peserta didik sebesar 81%, sehingga buku petunjuk praktikum yang telah dikembangkan itu termasuk kedalam kategori baik untuk digunakan.AbstractAfter five figures for the year since 2016, the science tadris study program only has basic biology and basic chemistry laboratories., Amun does not yet have a basic physics laboratory. Of course this is very much even though physics learning is closely related to the existence of practicum activities in the laboratory. Procurement of laboratories that have long and long procedures becomes an obstacle to learning physics. Phet provides many learning simulations and can be used as a virtual laboratory but has no instructions for using them. The purpose of this study was to develop virtual pet laboratory-based practical instructions on basic physics learning in science tadris. This type of research is to use the ADDIE type development research type, the product developed is validated by material experts, media experts, linguists, lecturers who teach then revised according to the suggestions then tested in the field and the amount of student response is calculated using a questionnaire. The results obtained are as follows: that the results of the feasibility test get an assessment from the basic physics material expert 1 gets an assessment of 85%, from basic physics material experts, linguists get an assessment of 80%, from media experts get an assessment of 78%, from, while the lecturers' assessment was 88%. So that when all the expert validators and lecturers are added up and then the average is getting a percentage of 86.2%. That means that the practicum manual that has been developed is valid and very feasible so that it can be used in further tests. When a small-scale field test, the response of students was 81%, which means that the practicum manual that had been developed was included in the good category to use.

Abstract

This research aims to determine the influence of students' learning activities on the ability to understanding mathematical concepts through the STEM Learning Approach Makerspace model based on PBL on SPLDV materials. As for the type of research Quasi-Experiments. The population in this study was 90 students who were distributed into 3 classes with 2 classes that sampled grades VIII A and VIII C. The sampling techniques in this study used randomized classes and data collection techniques in this study were tests and observations, while the research instruments used preliminary tests and final tests to measure the ability to understand mathematical concepts and observation sheets to see students' learning activities. Data analysis techniques using a two-way ANOVA test. The research showed that there is an influence of the PBL-based Makerspace STEM Learning Approach model on the ability to understand mathematical concepts, there is no influence on students' learning activities on mathematical concept comprehension capabilities, and there is no interaction between the PBL-based Stem Learning Approach Makerspace model and student learning activities on the ability to understand mathematical concepts. Conclusion, there is a positive direct effect of cognitive structures on the ability to understanding mathematical concepts.

Abstract

The purpose of this study was to produce an instruments test used to measure students' critical thinking skills in natural science learning. This research uses a 4-D development model (define, design, develop, and disseminate) involving 118 students at the develop stage and 60 students at the disseminate stage. The instrument developed was an essay test based on multiple representations. Validity was proved by using CVI, and reliability was estimated by using the Item Response Theory. The results showed that the instrument had a very good foreign exchange value. This is reflected in the Aiken V scores on the aspects of substance, construct, language and appearance, respectively, about 1.00, 1.00, 1.00, and 1.00. According to Rasch analysis, the instruments has meet the assumption test for 14 items which is unidimensional, the local independence assumption test, and the parameter invariance assumption test. According to OUTFIT MNSQ Value, the items are fit with PCM 1-PL which functions normally in making measurements. Reliability estimated for items shows a very high consistency of measurement of 0.97 and for person shows a high consistency of measurement of 0.86. The results of the student's CTS measurement showed that the average score was 65.50, with a distribution of high, medium, and low abilities, respectively, about 16.67%, 63.33%, and 20.00%. Thus, according to these results, an authentic assessment based on multiple representations is suitable to measure students' critical thinking skills.
