Abstract

Eliciting students’ mental model will enable teachers to monitor their students’ learning and understanding students’ mental model is a growing area of scientific inquiry in chemistry education. Diagnostics test can help teachers to understand the state of students’ understanding about certain topics and therefore, we developed a diagnostics test for eliciting students’ mental model about solubility equilibria. The developed diagnostics test was specifically designed to elicit mental model and rooted in Predict-Observe-Explain scheme, hence we called it as DTM-POE. After a series of DTM-POE trials, implementation results suggested that the developed DTM-POE can elicit students’ mental model about solubility equilibria. Several types of students’ mental models were found and DTM-POE sensitivity to elicit these mental models is discussed.

Abstract

Mental model plays an important role in giving reasons, describing, explaining, predicting, testing new ideas, and solving problems. Research on the mental model still needs to be done, especially regarding acid-base which is revealed by using Interview About Event (IAE). The purpose of this study was to analyze the students' mental models on the Arrhenius acid-base concept, the concept of Brӧnsted-Lowry acid base, and acid-base strength. The study was conducted on six students of class XII IPA in one high school in Bandung by using interviews that ask students to explain the given phenomenon. The answers of each student are mapped so as to derive their mental model profile. Based on the pattern obtained, there is found misconception experienced by students that all substances having atom H or OH group on chemical formula is Arrhenius acid or base, proton transfer on acid-base reaction Brӧnsted-Lowry occurs from acid to its conjugate base or from base to conjugate acid , The arrow of the reaction both in the perfect ionisation reaction and the partial ionization reaction is the same ie the arrow one (), the solute particles present in the solution in the ionizing agent are only partially ions (in the absence of molecules). Findings are useful for developing learning strategies, textbooks, media and other learning tools by linking the different levels of chemical representation to build meaning so that students' understanding is better. Keywords: acid basa, Interview About Event (IAE), misconception, mental model.AbstrakModel mental berperan penting dalam memberikan alasan, menggambarkan, menjelaskan, memprediksi, menguji ide-ide baru, dan memecahkan masalah. Penelitian mengenai model mental masih perlu dilakukan, khususnya mengenai asam-basa yang diungkap dengan menggunakan Interview About Event (IAE). Tujuan dari penelitian ini adalah untuk menganalisis model mental siswa pada konsep asam basa Arrhenius, konsep asam basa Brӧnsted-Lowry, dan kekuatan asam basa. Penelitian dilakukan terhadap enam siswa kelas XII IPA di salah satu SMA di Kota Bandung  dengan  menggunakan wawancara yang meminta siswa untuk menjelaskan fenomena yang diberikan.  Jawaban setiap siswa dipetakan sehingga diperoleh profil model mental mereka. Berdasarkan pola yang diperoleh, ditemukan miskonsepsi yang dialami siswa yaitu semua zat yang memiliki atom H atau gugus OH pada rumus kimianya merupakan asam atau basa Arrhenius, transfer proton pada reaksi asam basa Brӧnsted-Lowry terjadi dari asam ke basa konjugatnya atau dari basa ke asam konjugatnya, tanda panah reaksi baik pada reaksi ionisasi sempurna maupun reaksi ionisasi sebagian adalah sama yaitu tanda panah satu (), partikel zat terlarut yang ada dalam larutan pada zat yang mengalami reaksi ionisasi sebagian hanya ion-ionnya saja (tanpa adanya molekul). Temuan bermanfaat untuk mengembangkan strategi pembelajaran, buku ajar, media dan perangkat pembelajaran lainnya dengan mempertautkan antar level representasi kimia untuk membangun makna sehingga pemahaman siswa menjadi lebih baik.

Abstract

Penelitian ini bertujuan untuk menganalisis miskonsepsi mahasiswa calon guru pada konsep particulate of matter. Metode yang digunakan dalam penelitian ini adalah survei dengan teknik pengumpulan data berupa two tier diagnostic test Particle Theory Diagnostic Instrument (PTDI) yang diadaptasi dari Treagust, Chandrasegaran, Crowley, Yung, Cheong dan Othman serta dikembangkan oleh Widhiyanti, observasi, dan wawancara yang diujikan pada mahasiswa calon guru program studi pendidikan kimia tingkat I sampai IV berjumlah 148 mahasiswa. Hasil penelitian menunjukkan bahwa mahasiswa mengalami miskonsepsi pada 10 butir soal dari 11 soal yang diberikan pada instrumen two tier diagnostic test. Konsistensi jawaban siswa pada setiap kategori tidak mencapai 10% dari jumlah jawaban benar, mahasiswa tidak memahami konsep secara mendalam. Hal ini dibuktikan dengan penurunan jumlah jawaban benar (pada tier 1) dan alasan benar (pada tier 2) dengan persentase lebih dari 10%. Dengan demikian, perlu dilakukan pendalaman materi particulate of mater pada mahasiswa calon guru kimia untuk mengatasi miskonsepsi yang terjadi.

Abstract

This study aimed to explore chemistry pre-service teacher view toward implementation of contextual learning in Organic Chemistry. The context that was investigated about is Organic Light Emitting Diodes (OLEDs), which was a novel display technology that is being used for smartphone display. Seventeen pre-service chemistry teachers were interviewed about their knowledge about organic chemistry, conjugated double bond, OLEDs and their view about implementing OLEDs context in organic chemistry learning. Three groups of questions were asked to the pre-service chemistry teacher, most of them indicating lack knowledge about detail information of OLEDs even though they really appreciate if OLEDs was introduced in Organic Chemistry learning especially in conjugated double bond and nature-generated organic compound topics.

Abstract

This research is a preliminary study that focuses on multi-representation analysis of the chemical bonding topic in three general chemistry of text books. The analysis was carried out to find out how concepts are explained based on the three levels of chemical representation, especially on ionic and covalent bonding, which are the basis for further research in developing intertextual-based learning strategies. Analysis was carried out at the macroscopic-symbolic and sub microscopic-symbolic levels usingmulti-representation analysis table that was adopted from Gkitzia et al., 201 for three general chemistry books, that are 1) Whitten, K.W, et.al. (2014).  Chemistry 10th edition. English: Brooks/Cole Cengage Learning; 2) Chang, R. (2010). Chemistry 10th edition. New York : The McGraw-Hill Companies; and 3) Silberberg, M.S, and Amateis, P.G. (2021). Chemistry: the molecular nature of matter and change 9th edition.  New York : The McGraw-Hill Companies. The analysis results show that book: Silberberg, M.S, and Amateis, P.G. (2021). Chemistry: the molecular nature of matter and change 9th edition.  New York : The McGraw-Hill Companies has the most complete macroscopic-symbolic and sub microscopic-symbolic representation levels on the four main concept labels of chemical bonding, so that they can become standard reference material in developing chemical representations that will be used in intertextual learning strategies.

Abstract

This study presents a literature review on the use of the three-tier diagnostic test in identifying students’ misconceptions in chemistry and offers insights into its effectiveness in educational evaluation. A literature review of studies from 2019 to 2024 shows that 71.43% of these tests use close-ended questions due to their efficiency in terms of time, cost, and data analysis, compared to 28.57% that use open-ended questions. Research findings indicate that this test has successfully identified misconceptions in various chemistry topics, such as equilibrium, chemical bonding, ionization energy, and acids-bases. The ability of the three-tier diagnostic test to detect misconceptions makes it an effective tool for improving students’ conceptual understanding. The findings indicate that the three-tier diagnostic test has been widely used to uncover students’ conceptual difficulties across various chemistry topics. Its use has shown promise in supporting more accurate and in-depth assessments compared to traditional evaluation methods. The review suggests that this type of diagnostic testing can enhance the quality of formative assessments and contribute to improved instructional planning.
