      Abstract: ANALYSIS OF SCIENTIFIC HABITS OF MIND ENERGY ISSUES INVENTORY (SHOMEII) INSTRUMENT: RASCH MODELAbstractScientific Habits of Mind (SHOM) is a thinking characteristic that individuals have in solving problems and making decisions. SHOM can be accomplished in learning such as physics education through discussion, debate, and issue-based learning. However, the instrument for measuring SHOM in physics education is still immature. The purpose of this research is to develop and identify the quality of the SHOM instrument with energy problems analyzed using Model Rasch. This instrument is known as the Scientific Habits of Mind Energy Issue Inventory (SHOMEII). The development was carried out with the 3D+1I model (defining, designing, developing and implementing), involving 280 high school students with an average age of 17 years and came from West Java, Indonesia. The instruments used were a validation sheet and a SHOMEII consisting of 22 items with 4 answer choices based on the level of confidence. The results of the analysis show that SHOMEII has excellent reliability, good validity, and varying levels of difficulty. Therefore, SHOMEII can be implication as an instrument to measure students' SHOM abilities in physics education.AbstrakScientific Habits of Mind (SHOM) merupakan karakteristik berpikir seperti ilmuwan dalam melakukan sesuatu, memecahkan masalah dan mengambil keputusan.

           INDONESIA: A CONTENT ANALYSIS

    • Authors: Dewi Fairuz Zulaikha, Jumadi Jumadi, Annisaa' Mardiani, Baiq Armita Lutfia
      Pages: 138 - 152
      Abstract: THE DEVELOPMENT OF PHYSICS LEARNING RESEARCH WITH STEM APPROACH IN INDONESIA: A CONTENT ANALYSISAbstractThis study aims to provide an overview of physics learning research with the STEM approach in Indonesia. This study used a thematic content analysis method which aims to determine the depth of the study using a certain matrix so that a conclusion can be presented based on similarities and differences. This study analyzed SINTA indexed scientific articles published from 2016-2020. The results of the search were obtained as many as 51 scientific articles according to the scope of the research. Research that is mostly done is experiments. The most widely used number of samples was 11-30 and the type of sample that was most studied was students in class XI in Senior High School. The most widely used data collection instrument is the test instrument. The most popular physics material is temperature and heat material, while the most measured research variable is students' understanding of concepts. The product that is mostly developed in learning with the STEM approach is students’ worksheets, while the learning model that is most often integrated with the STEM approach is Project-Based Learning (PjBL). In the future, research should examine the effects of learning physics using the STEM approach on variables that are still rarely studied, such as students' representational abilities. In addition, it is necessary to apply a STEM learning approach to other materials that are still rarely used. Thus, it can be concluded that this study has provided preliminary information for further research and policy determination on the STEM approach in physics learning.AbstrakTujuan penelitian ini adalah untuk memberikan tinjauan umum terkait penelitian pembelajaran fisika dengan pendekatan STEM di Indonesia. Penelitian ini menggunakan metode thematic content analysis yang bertujuan untuk menentukan kedalaman penelitian dengan menggunakan matriks tertentu sehingga dapat disajikan suatu kesimpulan berdasarkan kesamaan dan perbedaan. Penelitian ini menganalisis artikel ilmiah terindeks SINTA yang dipublikasikan dari 2016-2020. Hasil dari pencarian diperoleh sebanyak 51 artikel ilmiah yang sesuai dengan lingkup penelitian. Penelitian yang banyak dilakukan adalah penelitian eksperimen. Jumlah sampel yang paling banyak digunakan adalah sebanyak 11-30 dan jenis sampel yang paling banyak diteliti adalah peserta didik di kelas XI SMA/MA. Instrumen pengumpulan data yang paling banyak digunakan adalah instrumen tes. Materi fisika yang paling diminati adalah materi Suhu dan Kalor, sedangkan variabel penelitian yang paling banyak diukur adalah pemahaman konsep peserta didik. Produk yang paling banyak dikembangkan dalam pembelajaran dengan pendekatan STEM adalah LKPD, sementara model pembelajaran yang paling sering diintegrasikan dengan pendekatan STEM adalah Project Based Learning (PjBL). Ke depannya penelitian sebaiknya mengkaji efek pembelajaran fisika dengan menggunakan pendekatan STEM terhadap variabel yang masih jarang diteliti, seperti kemampuan representasi peserta didik. Selain itu, perlu diterapkan pendekatan pembelajaran STEM pada materi lain yang masih jarang digunakan. Dengan demikian, dapat disimpulkan bahwa penelitian ini telah memberikan informasi awal untuk penelitian dan penentuan kebijakan lebih lanjut tentang pendekatan STEM dalam pembelajaran fisika.

      Abstract: ANALISIS SIKAP SISWA TERHADAP STEM BERDASARKAN GENDER DAN TINGKATAN KELAS: STUDI KOMPARASI INDONESIA DAN THAILANDAbstractAttitude is a tendency to behave and react to a given stimulus. The smoothness of STEM learning involves students, one of which is students' attitude towards STEM. Students at the junior high school level are a transitional period from children to adolescents who are not yet considered adulthood. Besides that, there is behavior stereotypical in male and female students during learning. This research was conducted to analyze students' attitudes towards Science, Technology, Engineering, and Mathematics (STEM) in Indonesia and Thailand in terms of grade level and gender. The research method used is descriptive quantitative using a survey. This study used the STEM questionnaire distributed to 139 students in Thailand and 90 students in Indonesia. Data were collected using a questionnaire about students' attitudes towards STEM and interview protocols for science teachers. Analysis of student attitudes, which focused on self-confidence, enjoyment, interest, and anxiety, showed that these attitudes were more dominant among students at the highest grade level in both countries. However, there is no significant difference between the attitudes of male and female students in Indonesia and Thailand; both are the same in responding to STEM learning.AbstrakSikap merupakan kecenderungan berperilaku dan reaksi terhadap stimulus yang diberikan. Kelancaran pembelajaran STEM yang melibatkan siswa, salah satunya adalah sikap siswa terhadap STEM. Siswa pada jenjang sekolah menengah pertama merupakan masa peralihan dari anak-anak menuju remaja yang belum dikatakan masa dewasa, selain itu adanya perilaku stereotype pada siswa laki-laki dan perempuan pada saat pembelajaran. Penelitian ini dilakukan untuk menganalisis sikap siswa terhadap Sains, Teknologi, Rekayasa, dan Matematika (STEM) di Indonesia dan Thailand ditinjau dari tingkat kelas dan jenis kelamin. Metode penelitian yang digunakan adalah kuantitatif deskriptif dengan menggunakan survei berupa kuesioner. Penelitian ini menggunakan kuesioner STEM yang dibagikan kepada 139 siswa di Thailand dan 90 siswa di Indonesia. Data dikumpulkan dengan menggunakan kuesioner tentang sikap siswa terhadap STEM dan protokol wawancara untuk guru IPA. Analisis sikap siswa yang berfokus pada kepercayaan diri, kesenangan, minat, dan kecemasan, menunjukkan bahwa sikap tersebut lebih dominan di antara siswa pada tingkat kelas tertinggi di kedua negara. Namun tidak ada perbedaan yang signifikan antara sikap siswa laki-laki dan perempuan di Indonesia dan Thailand, keduanya sama dalam merespon pembelajaran STEM.

      Abstract: IDENTIFIKASI MISKONSEPSI SISWA MENGGUNAKAN UJI ISOMORFIK: KASUS HUKUM NEWTON TENTANG GERAKAbstractStudents' misconceptions can lead to learning failure if they are not addressed. In this study, using Google Form, we identify students’ misconceptions using the isomorphic test method on Newton's Law of Motion, especially the principles of dynamics. This study is quantitative research conducted in three junior high schools in South Tangerang. There are 90 participants involved that was selected by purposive sampling method. The research instrument was an isomorphic test in form of multiple choice with nine questions with three indicators namely: analyzing the application of Newton’s I law in daily life; analyzing the correlation between force and mass and the acceleration of a moving object; and analyzing the application of Newton’s III Law in daily life. The results showed that the students were identified as having misconceptions in Newton’s Law concept using isomorphic tests, including misconceptions of inertia and misconceptions of Newton’s Third Law of Motion. One of the misconceptions is that students assume an object will maintain its initial position in motion by applying a new force in the opposite direction. The students' misconceptions found in this study can be used as a reference so that they can be overcome in the learning process.AbstrakMiskonsepsi dapat menyebabkan siswa sulit belajar jika tidak segera diatasi. Dalam penelitian ini, dengan menggunakan Google Form, kami mengidentifikasi miskonsepsi siswa menggunakan instrumen tes isomorfik pada materi Hukum Newton tentang gerak, khususnya pada prinsip-prinsip dinamika. Studi ini merupakan penelitian kuantitatif yang dilaksanakan di tiga SMP di Tangerang Selatan. Terdapat 90 partisipan yang dilibatkan yang dipilih dengan metode purposive sampling. Instrumen penelitian berupa tes isomorfik berupa pilihan ganda dengan sembilan soal dengan tiga indicator yaitu menganalisis penerapan hukum I Newton dalam kehidupan sehari-hari; menganalisis hubungan antara gaya dan massa dengan percepatan suatu benda yang bergerak; dan menganalisis penerapan Hukum 3 Newton dalam kehidupan sehari-hari. Hasil penelitian menunjukkan bahwa siswa teridentifikasi mengalami miskonsepsi pada konsep Hukum Newton. Diantara miskonsepsinya adalah siswa berasumsi bahwa benda akan mempertahankan posisi awalnya dalam gerak dengan memberikan gaya baru dalam arah yang berlawanan. Miskonsepsi siswa yang ditemukan dalam studi ini dapat menjadi referensi sehingga dapat diatasi dalam proses pembelajaran.

      Abstract: ANALISIS UJIAN AKHIR KIMIA BERDASARKAN KOMPLEKSITASKOGNITIF TAKSONOMI BLOOMAbstractSchool exams has been used by teachers to determine the success of students’ learning. This research is aimed to determine the extent of students learning through an analysis of end-of-year exam items based on Bloom’s cognitive complexity. The exam instruments are gathered from chemistry teachers of 5 public schools, consisting of in total 190 5-multiple-choice items. Qualitative approach and theory-driven content analysis method using Bloom’s revised taxonomy of cognitive complexity were employed in the research.  The result of this research showed that the majority of items (82.7%) determined students learning lower order cognitive skills (remember, understand, and apply). Skill of the analysis is the only higher order cognitive skill that has been found in the exam questions (17.3%). With regards to knowledge dimension, it was found that conceptual knowledge weighed the most among other dimensions (54.7%). It is interesting to see, however, that, the highest procedural knowledge was seen in the application skills (27.9%).  This research suggests that chemistry teachers need to carefully determine exam questions according to the cognitive complexity in order to ensure the extent of students learning. For curriculum developer, this research can be used to consider the depth of students’ learning outcomes as they serve as the foundation for exam development. Further research can be done to determine the gap between the exams and the expected learning outcomes. This will be beneficial to understand the extent to which schools can go higher than the minimun learning outcomes determined by the government.AbstrakUjian sekolah telah digunakan oleh guru untuk menentukan keberhasilan belajar siswa. Penelitian ini bertujuan untuk mengetahui sejauh mana siswa belajar kimia melalui analisis materi ujian akhir sekolah berdasarkan kompleksitas kognitif Bloom. Instrumen ujian dikumpulkan dari 5 sekolah umum, yang terdiri dari 190 item soal pilihan ganda. Pendekatan kualitatif dan metode analisis isi yang digerakkan oleh teori menggunakan taksonomi kompleksitas kognitif Bloom yang telah direvisi digunakan dalam penelitian ini. Hasil penelitian menunjukkan bahwa sebagian besar soal (82,7%) merupakan soal-soal dengan tingkat kognitif rendah (mengingat, memahami, dan menerapkan). Keterampilan analisis adalah satu-satunya keterampilan kognitif tingkat tinggi yang ditemukan dalam soal-soal ujian (17,3%). Untuk dimensi pengetahuan, ditemukan bahwa pengetahuan konseptual paling banyak di antara dimensi lainnya (54,7%). Menarik untuk dilihat, bagaimanapun, bahwa pengetahuan prosedural tertinggi terlihat pada keterampilan aplikasi (27,9%). Penelitian ini menyarankan guru untuk mempertimbangkan kompleksitas kognitif untuk memastikan sejauh mana siswa belajar.
