Abstract

The aim of this study was to investigate the effect of 5E learning cycle instructional model using socioscientific issues (SSI) learning context on students’ critical thinking skills of acid-base. This study used quasi-experimental posttest only control group design. The sample consisted of three classes, which were XI MIA-4class (n = 32) that learned using 5E LC model, XI MIA-5 class (n = 33) that learned using 5E LC+SSI, and XI MIA-6 class (n = 32) that learned using conventional method. The samples were choosen by convenience sampling technique. The test instrument consisted of 15 multiple choice items which were valid and reliable (r = 0.806). The data were analyzed using one way ANOVA test and LSD posthoc test. The results of this study indicated that the students who learned using 5E LC+SSI model showed greater levels of critical thinking skills (  = 74,95) than both the student who learned using 5E LC model (  = 74,17) and  the student who learned using conventional method (  = 68,96). Based on statistics analysis, there was significant differences on students’ critical thinkings between students taught using conventional method and students taught either using 5E LC+SSI model and 5E LC model. However,  there was no significant differences on students’ critical thinking skills between students taught using 5E LC+SSI model and the students taught using 5E LC model.

Abstract

Miskonsepsi merupakan masalah besar yang telah menjadi pusat perhatian bagi para pendidik dan peneliti pendidikan pada mata pelajaran ilmu pengetahuan alam, khususnya kimia. Salah satu  materi dalam kimia yang dianggap siswa cukup sulit sehingga tinggi kemungkinannya untuk terjadi miskonsepsi adalah materi kesetimbangan kimia. Miskonsepsi pada siswa perlu diidentifikasi dengan cepat supaya dapat segera ditangani sehingga tidak menganggu pembelajaran selanjutnya. Penelitian ini bertujuan untuk mengidentifikasi miskonsepsi siswa pada materi kesetimbangan kimia menggunakan tes three tier berbasis web. Metode penelitian yang digunakan adalah deskriptif kuantitatif. Responden pada penelitian ini adalah 178 siswa SMA kelas 11. Hasil dari penelitian ini menunjukkan persentase rata-rata miskonsepsi yang dialami siswa pada setiap konsep dalam materi kesetimbangan kimia berkisar antara 43,91% - 62,06%. Siswa mengalami miskonsepsi pada konsep kesetimbangan kimia, konsep tetapan kesetimbangan kimia, dan konsep Prinsip Le-Chatelier. Selain itu, penelitian ini juga menunjukkan bahwa tes three tier berbasis web dapat mengefisienkan waktu dalam mengolah data dan identifikasi miskonsepsi

Abstract

Penelitian ini bertujuan untuk menguji pengaruh pembelajaran POGIL berkonteks SSI terhadap kualitas argumentasi siswa kelas X. Rancangan penelitian adalah mixed-methods. Data kuantitatif berupa tingkat kualitas argumentasi siswa yang diperoleh melalui instrumen tes keterampilan berargumentasi. Data kualitatif berupa hasil wawancara siswa tentang sikap siswa terhadap SSI dan argumentasi siswa pada proses pembelajaran. Hasil penelitian menunjukkan bahwa terdapat perbedaan keterampilan berargumentasi antara siswa yang dibelajarkan dengan POGIL berkonteks SSI dengan siswa yang dibelajarkan dengan POGIL dan konvensional. Pembelajaran POGIL berkonteks SSI lebih efektif dalam membelajarkan keterampilan berargumentasi siswa dibandingkan dua kelas lainnya berdasarkan nilai rata-rata kualitas argumentasi. The effect of POGIL with socioscientific issues context for high school argumentation skills quality in chemical bonding AbstractThe aim of the study was to examine the influence of POGIL with SSI context on the quality of high school students argumentation. The research design was mixed-methods. Quantitative data in the form of level of students’ argumentation quality collected by instrument of argument skills. Qualitative was the students’ transcript of interview about their attitude toward SSI and their argumentation in process of learning.The results showed that there was a difference in the skills of argumentation between the students who taught with the POGIL with SSI context and the students taught by POGIL and conventional instruction. POGILS with SSI context was more effective in teaching students’ argumentation skills compared to the other classes based on the average score of student argumentation.

Abstract

In the world of education, attainment of competence does not only involve increasing knowledge but must be equipped with creative abilities, high-level thinking, strong character, and supported by the ability to utilize information and communication. One way to achieve these competencies is by using blended learning-based problem-based learning methods. This study seeks to review articles on improving students' higher-order thinking skills using blended learning based on problem-based learning methods to investigate the combination of these two methods in increasing students' HOTS.

Abstract

This research aims to develop and validate chemical literacy test instruments on competency and knowledge aspects and to measure the chemical literacy of first-year science education students. Instrument development involved expert consultation, expert judgment, and testing of 114 first-year students majoring in chemistry for the analysis of item validity and instrument reliability.  The instrument was developed using the  Research& Development model by Borg and Gall (1989). The developed instrument consisted of 30 valid item items with Cronbach's Alpha reliability coefficient of 0.718. The analysis was carried out on 28 first-year students of the Jember State University Science Education Study Program who had studied carbon chemistry. Data analysis showed that the average score of students' chemical literacy was 59.7 in the moderate category.ReferencesAdawiyah, R., & Wisudawati, A. (2017).

Abstract

Berbagai survei menunjukkan bahwa pemahaman peserta didik terhadap kesetimbangan kimia masih rendah. Hal ini menyebabkan peserta didik mengalami kesulitan dalam memahami materi kimia yang membutuhkan pengetahuan prasyarat kesetimbangan kimia. Tujuan penelitian adalah untuk mengetahui kesulitan peserta didik dalam memahami kesetimbangan kimia dan  mengetahui konsep kesetimbangan kimia yang sulit dipahami oleh peserta didik. Penelitian ini menggunakan rancangan penelitian deskriptif. Pengambilan data dilakukan menggunakan instrumen tes tertulis yang terdiri atas 26 soal pilihan ganda dengan alasan terbuka. Hasil penelitian menunjukkan bahwa kesulitan peserta didik dalam memahami konsep kesetimbangan dinamis  tergolong  tinggi, konstanta kesetimbangan tergolong rendah, dan faktor-faktor yang mempengaruhi pergeseran kesetimbangan tergolong  rendah. Konsep  kesetimbangan kimia yang  paling  sulit  dipahami  oleh peserta didik adalah kesetimbangan dinamis dan konstanta kesetimbangan.

Abstract

Conceptual understanding of the subject matter is crucial for teachers in conducting instruction. The covalent bond is one of the essential knowledge of chemistry. This knowledge underlies most of the chemistry body knowledge. The purpose of this study is to investigate the chemistry teachers' conceptual understanding of covalent bonds. This study applied a descriptive qualitative research design. The research subjects were eight chemistry teachers from different schools. Data collection was carried out using a diagnostic interview technique guided by the semi-structured interview protocol. Data analysis was performed using phenomenography techniques. The results show that 25.00% of the interviewees well understood the covalent bond concepts, 22.75% do not understand, and 52.25% have misconceptions. Chemistry teachers have misconceptions about the concepts of intents of atom forming bonds, coordination bonds, types of atoms that form covalent bonds, polar and nonpolar covalent bonds, the level of covalent bonds polarity, Lewis structure writing, and covalent bond length.

Abstract

Abstrak: Peningkatan kualitas pembelajaran dengan menerapkan pembelajaran STEM sebagai suatu pendekatan preventif diharapkan mampu membantu siswa memaknai pembelajaran khususnya sains sehingga berimbas pada peningkatan keterampilan argumentasi. Pendekatan STEM disajikan sebagai jawaban atas tuntutan kebutuhan generasi berkualifikasi tinggi yang terfokus pada integrasi dari sains, teknologi, engineering dan matematika. Pengintegrasian STEM yang berkaitan dengan masalah kontekstual dianggap saling mendukung dengan pembelajaran sains yang memiliki relevansi dengan kehidupan. Namun dalam penerapannya, ditemukan variasi terkait pandangan tentang peran berbagai disiplin ilmu dalam pengintegrasian STEM. Hasil dari kajian literatur ini diharapkan berkontribusi pada rekomendasi penerapan pendekatan STEM dalam pembelajaran termasuk pada kebebasan untuk memahami dan menerapkan STEM di kelas bergantung pada kapasitas, kebutuhan, atau kenyamanan oleh guru maupun siswa.
