Abstract

Mathematical communication skills are a component of higher-order thinking skills that are important in 21st-century learning and support complex mathematical problem-solving. The purpose of the study was to determine the effect of the implementation of STEM-integrated guided inquiry learning on improving students' mathematical communication skills. his study used a pretest-posttest control group design and a quantitative, quasi-experimental methodology. All eighth-grade students from SMPN in Bandar Lampung, who were divided among eight classes for the 2024/2025 academic year, made up the study's population. Using a purposive sampling strategy, the research sample was chosen from two classes: class 8.1, which had 28 students as the experimental class, and class 8.2, which had 24 students as the control class. Based on the results of statistical analysis with the Mann-Whitney U test, it was concluded that the improvement in mathematical communication skills of students who participated in STEM-integrated guided inquiry learning was higher than the improvement in mathematical communication skills of students who participated in the traditional learning paradigm. Thus, the implementation of STEM-integrated guided inquiry learning can improve students' mathematical communication skills.

Abstract

One of the important mathematical thinking skills that students master is critical thinking skills. In fact, students' mathematical critical thinking skills in Indonesia are still relatively low. One of the factors that cause students to have low mathematical critical thinking skills is the use of less creative media. This study was conducted by analyzing the effect of using H5P interactive media on mathematical critical thinking skills. The purpose of this study was to determine the effect of using H5P Interactive Media on the mathematical critical thinking skills of students in grade IX SMP Negeri 1 Ketapang. The samples in this study were students of class IX B as the experimental class and students of class IX C as the control class. The design used was a pretest-posttest control group design. The data of this research is quantitative data obtained from a mathematical critical thinking ability test. Based on the results of hypothesis testing using a t-test with α = 0.05, it was found that the increase in mathematical critical thinking ability of students who took part in learning by using H5P interactive media was higher than the increase in mathematical critical thinking ability of students who took part in learning without using H5P interactive media. It can be concluded that the use of H5P interactive media has an effect on students' mathematical critical thinking skills.

Abstract

This study aims to determine the effect of problem-based learning model on students' mathematical critical thinking skills. The population of this study is all seventh grade students of SMP Negeri 1 Natar even semester of the 2023/2024 academic year as many as 371 students distributed into eleven classes, namely VII A to VII K. Sampling was carried out using purposive sampling technique, so that VII A class of 34 students was selected as the experimental class and VII D of 33 students as the control class. The design used was pretest-posttest control group design. The data in this study are quantitative data obtained through the mathematical critical thinking ability test. Based on the Mann-Whitney U test results, it was found that the improvement in mathematical critical thinking skills of students who participated in learning with problem-based learning was higher than the improvement in mathematical critical thinking skills of students who participated in conventional learning. In addition, based on the results of the proportion test, it was found that more than 60% of students who participated in problem-based learning were categorized as good. So it can be concluded that the problem-based learning model has an effect on students' mathematical critical thinking skills.

Abstract

Mathematical reflective thinking skills and self-concept are essential aspects of 21st-century learning to address global challenges. This study analyzes the effect of Project-Based Learning (PjBL) on students' mathematical reflective thinking skills and self-concept. The experimental research involved 75 tenth-grade students in Bandar Lampung using a posttest control group design. Data were collected through mathematical reflective thinking skills tests and self-concept questionnaires and analyzed using parametric and non-parametric statistical tests. The results showed that the implementation of PjBL did not significantly affect students' mathematical reflective thinking skills and self-concept compared to conventional learning. However, the indicators of mathematical reflective thinking skills achievement in the PjBL class were higher. This study implies the need for a longer implementation of PjBL to achieve significant results and its potential contribution to developing students' collaboration, creativity, and social skills as part of holistic learning.

Abstract

The purpose of the study was to determine the implementation of learning with the STEM approach to improving students' mathematization skills. The STEM approach includes science, technology, engineering, and mathematics in real context. The study population was all VIII grade students of SMP Negeri 33 Bandarlampung in the odd semester of the 2024/2025 academic year which were distributed in six classes, namely VIII A to VIII F heterogeneously. Sampling was done using cluster random sampling technique, VIII E class consisting of 32 students was selected as the experimental class and VIII D class consisting of 32 students as the control class. The research design used was pretest-posttest control group design. The data of this research is quantitative data obtained from the students' mathematization skills test. The test consists of three descriptive questions that have been tested and meet the validity and reliability criteria. Based on data analysis using Mann-Whitney U test, it was concluded that the improvement of mathematization skills of students who participated in learning with STEM learning was higher than the improvement of mathematization skills of students who participated in conventional learning. Thus, the implementation of STEM learning can improve students' mathematization skills.

Abstract

Pendidik profesional harus terus memperbarui empat kompetensi utama, termasuk kompetensi profesional. Dengan adanya perbaikan struktur kurikulum dan tuntutan adaptif dari berbagai sektor, guru dituntut untuk meningkatkan profesionalitasnya. Dalam konteks kurikulum merdeka, guru menghadapi tantangan dalam pengembangan pembelajaran, khususnya dalam pendalaman konsep. Survei menunjukkan bahwa guru matematika SMA di Bandar Lampung sangat membutuhkan pendalaman konsep statistika regresi, yang merupakan bagian dari kurikulum merdeka, dan 100% guru melaporkan bahwa siswa kesulitan memahami materi tersebut. Oleh karena itu, kegiatan workshop kolaboratif reflektif pengembangan pembelajaran materi regresi linier berbantuan teknologi bagi guru matematika Kota Bandar Lampung dilaksanakan yang bertujuan untuk meningkatkan pemahaman guru-guru dalam menggunakan teknologi pada pembelajaran konsep regresi linier. Evaluasi dilakukan melalui pretest dan posttest, dengan hasil menunjukkan peningkatan pemahaman peserta. Rata-rata skor meningkat dari 35,75 menjadi 62, dengan N-Gain sebesar 0,39 (kategori sedang). Meskipun sebagian besar peserta mengalami peningkatan di kategori sedang, antusiasme tinggi terlihat dalam penggunaan software SPSS, meski beberapa guru menghadapi kesulitan teknis. Rekomendasi untuk pelatihan berikutnya adalah memberikan lebih banyak waktu eksplorasi mandiri untuk adaptasi teknologi.
