IDENTIFIKASI MISKONSEPSI DALAM MENYELESAIKAN SOAL PERTIDAKSAMAAN LINEAR SATU VARIABEL YANG MEMUAT NILAI MUTLAK

This research aims to describe the forms of student misconceptions and the factors that cause misconceptions experienced by students in solving linear inequality problems with one variable containing absolute values in class X SMA Muhammadiyah 1 Pontianak. The subjects of this research were students of class X IPA 3 SMA Muhammadiyah 1 Pontianak, totaling 25 students. The research uses descriptive method as the research method. Case study is a form of research used. The results of the research revealed that the research subjects experienced five forms of misconception, namely notation misconceptions experienced by 1 student or by 4%, generalizing misconceptions experienced by 3 students or by 12%, misconceptions of the application of rules experienced by 6 students or by 24%, calculation misconceptions experienced by 2 students or by 8%, and specialization misconceptions experienced by 3 students or 12%. The misconceptions experienced by these students are caused by wrong intuition and incomplete reasoning, where students' intuitive thoughts that arise spontaneously when solving problems are still wrong and students' reasoning or logic is still wrong in drawing conclusions and being too broad in generalizing. Keywords: Misconceptions, Two-Tier Diagnostic Test, One Variable Linear Inequality Problem with Absolute Values

A Four-tier Diagnostic Instrument: An Analysis of Elementary Student Misconceptions in Science Topic

Learning science in elementary schools encourages students to understand the natural environment more deeply, rationally, and scientifically. However, often the scientific concepts they believe about science topics are not in accordance with the scientific concepts they should be. This misconception is difficult for teachers to diagnose. Special instruments to identify and analyze students' misconceptions are needed. Therefore, this research aims to analyze the misconceptions of elementary school students on the topic of energy using a four-tier diagnostic instrument. The purposed-designed survey method was used in this study. The data were analyzed quantitatively and qualitatively. The participants in this study were 20 fourth grade students in an elementary school in Ciamis Regency. A total of 6 questions in the form of a four-tier diagnostic instrument were used to determine the level of students' conceptions. The results showed that the students have misconceptions about the concept of energy. This can be seen from the average percentage of students' misconceptions of 66.67%. This research is expected to contribute to alternative ways to identify and analyze students' misconceptions using the four-tier diagnostic instrument. In addition, it can be used as a reference for teachers and researchers related to the problem of misconceptions of science in elementary school students

Pelatihan Peningkatan Kemampuan Guru untuk Mengidentifikasi Miskonsepsi Peserta Didik Pada Pembelajaran Kimia Bagi Guru Kimia Se-Kalimantan Selatan

Pembelajaran kimia sangat sensitif terhadap perspektif peserta didik. Ketika peserta didik tidak diarahkan dengan tepat maka akan berpeluang munculnya miskonsepsi. Tujuan kegiatan Pengabdian kepada Masyarakat (PkM) ini adalah 1) mendeskripsikan cara meningkatkan kemampuan guru dalam mengidentifikasi miskonsepsi peserta didik, dan 2) efektivitas pelatihan yang dilakukan terhadap peningkatan kemampuan guru dalam mengidentifikasi miskonsepsi peserta didik. Pelatihan ini diikuti oleh guru SMA yang tergabung dalam MGMP guru kimia. Teknik pengumpulan data yaitu teknik dokumentasi, observasi, dan wawancara agar memeproleh informasi yang jelas dari para responden. Teknik analisis data menggunakan analisis kualitatif dengan tujuan untuk mendeskripsikan fenomena yang terjadi selama proses kegiatan. Hasil kegiatan PkM diperoleh bahwa cara untuk meningkatkan kemampuan guru dalam mengidentifikasi miskonsepsi peserta didik yakni, 1) mengembangkan suatu tes diagnostik berbasis pilihan ganda/essai, 2) melakukan tes diagnostik kepada peserta didik baik sebelum ataupun sesudah proses pembelajaran, dan 3) menyajikan materi kimia dengan mengintegrasi fenomena atau kehidupan sehari-hari. Kemudian, efektivitas pelatihan yang dilakukan terhadap peningkatan kemampuan guru dalam mengidentifikasi miskonsepsi peserta didik yakni dengan menyajikan konsep belajar kimia berbasis kimia representasi. Kegiatan ini menjadi salah satu strategi dalam mereduksi miskonsepsi peserta didik. Chemistry learning is very sensitive to students' perspectives. When students are not appropriately directed, there will be opportunities for misconceptions to arise. The objectives of this Community Service activity are 1) to describe how to improve the teacher's ability to identify student misconceptions, and 2) the effectiveness of the training carried out to increase the teacher's ability to identify student misconceptions. This training was attended by high school teachers who are members of the chemistry teacher MGMP. Data collection techniques are documentation, observation, and interview techniques to obtain clear information from the respondents. The data analysis technique uses qualitative analysis to describe the phenomena that occur during the activation process. The results of the community service activity showed that the ways to improve the teacher's ability to identify students' misconceptions were, 1) developing a multiple-choice/essay-based diagnostic test, 2) conducting diagnostic tests to students both before and after the learning process, and 3) presenting chemistry material by integrating phenomena of everyday life. Then, the effectiveness of the training carried out on improving the ability of teachers to identify students' misconceptions is by presenting the concept of learning chemistry based on representational chemistry. This activity is one of the strategies in reducing students' misconceptions.

Analysis conception of secondary student’s using four tier test on heat and temperature

The main purpose in this research is to analyse student conception about heat and temperature used four tier test question, the test consists of three question including material about temperature, temperature and heat, as well specific heat. The research has been implemented by using purposive sampling technique. The participants consisted of 67 secondary students including (23 male students and 44 female students) of senior high school in Bungo city. After the analysis obtained the largest percentage of student conception id in the category of misconception such as: (1) Objects that feel colder to the touch must be lower in temperature than objects that feel warmer to the touch; (2) Objects that have a higher temperature must have more calorific content than objects with lower temperatures; (3) Objects that are easier to increase in temperature when heated, it will be more difficult to decrease the temperature when cooled. One way to reduce student misconceptions of concept in temperature and heat material is to facilitate student learning using conceptual change model, conceptual change text or Refutation text.

Five-Tier Diagnostic Test to Reveal Conceptual Understanding of Electrical Engineering Students

The purpose of this research was to produce a valid five-tiered misconception diagnostic assessment product and reveal the understanding of electrical engineering students' concepts on the subject of simple electrical circuits. Assessment development consisted of defining, designing, developing, and disseminating stages. Data collection techniques were online questionnaire methods, online tests, and online interviews. Construct validity was obtained that the assessment was valid and reliable. A total of 19 questions were categorized as medium and one easy question. The analysis of the conceptual understanding test obtained results 29.98% of students who understood the concept, 31.4% did not understand the concept, 2.82% of false positive, 3.38% of false negative, and 31.12% with misconception. There were 26 kinds of student misconceptions identified. The dominant misconception identified in the concept of circuit resistance arrangement was 40.2%. Students assumed that electrons flow from high to low potential in a closed circuit with a DC voltage source. The research results in a five-tier diagnostic assessment can be used in vocational colleges in general. The results of data analysis show that the five-tier format of the assessment can reveal students' misconceptions in detail and, more specifically, distinguish students who have misconceptions from students who are false positive and false negative to reveal students who have misconceptions better. The researcher's development procedure can be used as an example for other researchers to develop a five-tier format diagnostic assessment on other basic concepts.

Phylogenetic trees and other evolutionary diagrams in biology textbooks and their importance in secondary science education

Diagrams describing relationship between organisms, and their overall evolution, commonly in the form of phylogenetic trees or other evolutionary diagrams, have become a part of even lower secondary biology textbooks. These diagrams can help promote basic science literacy, yet their design may also strengthen misconceptions about evolution. Therefore, based on the content analysis of 112 Czech biology textbooks for secondary schools (ISCED levels 2 and 3), characteristics of introduced phylogenetic trees and other evolutionary diagrams were recorded and evaluated according to the cladistics to see if their construction supports the current scientific understanding of evolution. The content analysis indicates that the design of nearly half of all diagrams in current lower (ISCED 2) and upper secondary (ISCED 3) textbooks promotes ladder thinking. More than 80% of all diagrams were not accompanied by instructions on how to read them, meaning that students did not have sufficient scaffolding to understand them. Mainly ISCED 3 textbooks did not introduce additional problem tasks that would support the use of the diagrams in the lessons. Therefore, authors of textbooks should focus more on the construction quality of these diagrams while also supporting their correct application during the educational process. This is likely to prevent a further increase in student misconceptions.
