Abstract

This research was conducted to build a view of the nature of science and technology (VNoST) chemistry education students' ability through the didactical design reconstruction. The material taken is Dye-Sensitized Solar Cells (DSSCs) topic with technochemistry education model. It is a model that looked at education from the perspective of engineers and scientists who work not only on inquiry but also on a design perspective. Based on literature research, Indonesian students had low academic literacy performance as revealed in PISA (Program for International Student Assessment) study from 2000-2015. This problem can be caused by a weak teacher's abilities of the nature of science and technology (VNoST). This research's method is Research and Development (R&D) through the Model of Educational Reconstruction (MER). The instruments used were the VNoST questionnaire, interview guidelines, and content analysis guidelines. This study's subjects were 25 prospective chemistry education students in the 6th semester for pre-conception study and ten students for implementation study at one of State Universities in Indonesia. The didactical design of learning that has been developed had several advantages, including the prediction of student responses and the anticipation of educators as well as the essential material that is a barrier to student learning. Analysis of the VNoST understanding construction patterns is explored further so that the reasons that underlie students in defining science and technology and their relationship are obtained. The implementation study proved that understanding VNoST students after attending didactical design learning improved by changing students' views on science and technology to be more accurate.

Abstract

This research aims to develop interactive multimedia by utilizing HPLC simulators to train students' analytical thinking skills, which will support dry lab practicum activities to be more meaningful. The research method is development research with a 4-D model design, defining, designing, developing, and disseminating. However, this research stage is limited to the development stage. The instruments used in this study include test and non-test instruments in student satisfaction questionnaires and observation of learning outcomes. The results showed that MMI assisted by an HPLC simulator helped students increase students' motivation and interest in studying HPLC material. In line with that, learning with the HPLC simulator can develop analytical thinking skills in the matching and classifying aspects, but has not trained in 3 other aspects, namely error analysis, generalizing, and specifying. It is recommended to use a learning approach such as STEM, which accommodates learning needs with the stages of inquiry, Engineering Design Process, and Product development to overcome the lack of development of analytical thinking skills in the aspects of analysis error, specifying, and generalizing.

Abstract

This study aimed to analyze the construction of teaching materials which are relevant to daily life using the theme of green batteries. The method used the model of educational reconstruction as a framework. This model consisted of three components, which are: analysis of content structure, re-search on teaching and learning, and development of learning settings. The discussion in this study was focused only on the analysis of content structure which required three stages, they are: analysis of literature, clarification of basic context, and modification of the text. First stage would produce indi-cators and learning objectives for cognitive and affective domains, which were based on the content of electrochemistry cells, the context of Li-ion batteries, and the scientific literacy. Second stage was the elementarization process of elektrokimiaic cell content and Li-ion batteries context. Third stage was the process of insertion and abolition of original text to become basic text. Validation through expert judgments was conducted for indicators and learning objectives of cognitive and affective domains based on the Standard of Competence, Basic Competence and competencies in PISA 2009.

Penelitian dilaksanakan di salah satu SMP yang berlokasi di Lembang, Kabupaten Bandung Barat pada 29 orang siswa kelas VII sebagai sampel yang telah dipilih menggunakan teknik random sampling. Instrumen penelitian yaitu tes berbentuk uraian (essay) sebanyak 6 butir soal yang disusun berdasarkan indikator kemampuan argumentasi (claim, data, warrant, backing). Instrumen yang digunakan divalidasi oleh tiga validator yaitu dua dosen ahli dan satu guru bidang studi IPA. Jawaban siswa dianalisis berdasarkan komponen argumentasi yang terkandung didalamnya. Hasil penelitian menunjukkan bahwa 93,10% siswa menuliskan claim, 54,02% siswa menuliskan data, 48,85% siswa menuliskan warrant, dan 45,40% siswa dapat menuliskan backing. Secara keseluruhan dapat disimpulkan bahwa sebagian besar siswa mampu menuliskan claim namun mulai mengalami kesulitan untuk mengemukakan data, warrant, dan backing. Persentase kemampuan awal siswa dalam berargumentasi tersebut dapat dijadikan sebagai acuan bagi guru sehingga kedepannya dapat menentukan desain atau kegiatan pembelajaran yang tidak hanya berfokus pada pemahaman konsep tetapi juga dapat membangun atau melatih kemampuan argumentasi siswa.This study aims to determine the argumentation ability of junior high school students related to environmental pollution. This study uses a descriptive research method with a quantitative approach. The research was carried out in one of the junior high schools located in Lembang, West Bandung Regency on 29 seventh grade students as a sample that had been selected using random sampling technique. The research instrument is a test in the form of a description (essay) of 6 questions which are arranged based on indicators of argumentation ability (claim, data, warrant, backing). The instrument used was validated by three validators, namely two expert lecturers and one science teacher. Students' answers were analyzed based on the argumentative components contained therein. The results showed that 93.10% of students wrote claims, 54.02% of students wrote down data, 48.85% of students wrote warrants, and 45.40% of students could write backings. Overall, it can be concluded that most of the students are able to write claims but are starting to have difficulty presenting data, warrants, and backings. The percentage of students' initial ability to argue can be used as a reference for teachers so that in the future they can determine designs or learning activities that not only focus on understanding concepts but can also build or train students' argumentation skills

Abstract

Rare Earth Elements (REE) is an interesting chemistry topic, especially due to current technology development. However, new learning designs of REE need to be developed for Pre-service Chemistry Teachers (PCT) as it is not yet available. A good design is constructed by analyzing PCT pre-conceptions based on the technical difficulties faced by the students during teaching process. The study aims to identify PCT's pre-conceptions focusing on REE topic. We conducted this research involving 17 chemistry education students at the Universitas Pendidikan Indonesia, Bandung. Data was collected through interviews and analyzed using the Qualitative Content Analysis (QCA) method. Our results highlight that PCT had difficulties with chemistry content of REE, especially about electronic configuration, magnetic, and luminescence properties. In addition, PCT faced difficulties correlating electronic configuration's chemistry content into contexts. Based on the interview results, 88.2% of the students agree with the development learning design for undergraduate chemistry students. As a result, we conclude that technical difficulties and misconceptions about REE can be overcome by developing the learning design based on the need of the students.
