Abstract

The learning system that was originally carried out at school became a long distance learning system at home which resulted in changes to student learning outcomes, especially in the derivative of trigonometic function. Students' limitations in understanding about derivative of trigonometric function became students’ learning obstacle during the pandemic. This study aims to analyze the epistemological obstacle of high school students in the derivative of trigonometric function during the pandemic. This study use qualitative method with case study design. The subjects of this study were 23 students of grade XII of Senior High School in Cirebon City and Garut Regency. Data collected by using test and semi-structured interview. Technical analysis of data using data reduction, data presentation and conclusion drawing. The results showed that students experienced an Epistemological Obstacle related to solving derivative problems of trigonometric functions, seen from students' errors in deriving basic trigonometric functions, derivatives in the form of multiplication, chain derivatives and derivatives involving mixed algebraic and trigonometric forms as well as errors in determining derivatives at a certain point.

Abstract

Abstrak Penelitian tentang implementasi STEM dalam pembelajaran semakin banyak dilakukan, sehingga perlu adanya penelitian yang merangkum hasil – hasil temuan penelitian STEM dalam pembelajaran Matematika khususnya pada kemampuan berpikir kritis dan kemampuan berpikir kreatif matematis. Penelitian ini bertujuan untuk memperoleh gambaran tentang implementasi pendekatan STEM (Sains, Technology, Engineering, and Mathematics) dalam meningkatkan kemampuan berpikir kritis dan kemampuan berpikir kreatif matematis pada tingkat SD, SMP, SMA dan Perguruan Tinggi. Systematic Literature Review (SLR) digunakan untuk mensintesis studi yang relevan dengan tujuan penelitian ini. Melalui mesin mencari Google Scholar, Directory Open Access Journal (DOAJ Semantic Scholar, serta Education Resources information Center (ERIC) diperoleh 28 studi primer yang diterbitkan dari tahun 2015 sampai tahun 2022 masuk kriteria inklusi untuk dianalisis lebih lanjut. Hasil penelitian memberikan informasi bahwa pendekatan STEM memiliki pengaruh yang positif terhadap peningkatan kemampuan berpikir kreatif dan berpikir kritis matematis siswa/mahasiswa. Project Based Learning dan Problem Based Learning merupakan model pembelajaran yang secara signifikan sesuai untuk diterapkan dalam pendidikan STEM. Beberapa tinjauan karakteristik penelitian seperti ukuran sampel, tingkat pendidikan dan tahun penelitian dapat diteliti lebih lanjut untuk penelitian selanjutnya. Integrasi STEM dengan model pembelajaran dapat digunakan oleh pendidik untuk memfasilitasi siswa dengan berbagai tugas berbasis proyek dan pemecahan masalah. Hasil penelitian ini memberikan kontribusi pengetahuan bagi pendidik dan peneliti tentang bagaimana seharusnya STEM diterapkan dalam pembelajaran matematika terkait dengan peningkatan kemampuan berpikir kritis serta kemampuan berpikir kreatif matematis siswa.Kata kunci: STEM, berpikir kreatif matematis, berpikir kritis matematis Abstract Research on the implementation of STEM in learning has been carried out, but there has been no research that summarizes the findings of STEM research in mathematics learning, especially on critical thinking skills and mathematical creative thinking skills. This study aims to obtain a description of the implementation of the STEM approach (Science, Technology, Engineering, and Mathematics) in improving critical thinking skills and mathematical creative thinking skills at the elementary, junior high, high school and university students. Systematic Literature Review (SLR) was used to synthesize studies relevant to the objectives of this study. Through the search engine Google Scholar, Semantic Scholar, Education Resources Information Center (ERIC) and Directory Open Access Journal (DOAJ), 28 primary studies published from 2015 to 2022 fitted the inclusion criteria for further analysis. The results of study showed that the STEM approach has a positive effect on increasing students' creative thinking skills and mathematical critical thinking skill. Project Based Learning and Problem Based Learning are learning models that are significantly suitable to be applied in STEM education. Several reviews of research characteristics such as sample size, education level and years of research can be investigated further for further research. The integration of STEM with learning models can be used by educators to facilitate students with various project-based tasks and problem solving. The results of this study contribute to knowledge for educators and researchers about how STEM should be applied in mathematics learning related to improving students' creative thinking and mathematical critical thinking skillsKeywords: STEM, creative thinking skills, mathematical critical thinking

Abstract

Studies on the effectiveness of STEM implementation in Mathematics learning, especially in mathematical creative thinking ability carried out by previous researchers, are interesting to be studied. However, several studies have shown different results that can lead to different interpretations. This study aims to estimate dan examine the effectiveness of STEM on students' mathematical creative thinking ability from the relevant studies. This study analyzed 12 primary studies from various electronic search engines within the year of publication from 2017 to 2022. All primary studies in this research were analyzed using the meta-analysis with Comprehensive Meta-Analysis 3.0 (CMA 3.0) software by selecting the formula of Hedge to determine its effect size. The results of this meta-analysis study indicated that the STEM approach was effective for students' mathematical creative thinking abilities with an effect size of 0,935 in the category of high effect. There were differences in the effect size of the STEM approach on students' mathematical creative thinking abilities regarding STEM integration with learning models and educational levels. This means that the type of integration of the STEM approach with the learning model and educational level significantly causes heterogeneity in students' mathematical creative thinking abilities. The results of this study are expected to provide educators with an overview of how STEM can be applied in mathematics learning, especially in improving mathematical creative thinking ability.
