Abstract

Penelitian ini bertujuan untuk mengetahui bahwa melalui pendekatan saintifik dengan reward, pemahaman matematika siswa dapat meningkat. Penelitian ini menggunakan metode kuasi eksperimen tipe embeded dengan tiga perlakuan di tiga kelas berbeda. Kelas eksperimen pertama diberi perlakuan pendekatan saintifik dengan reward, kelas eksperimen kedua diberi perlakuan pendekatan saintifik tanpa reward, dan kelas kontrol yang diberi perlakuan pembelajaran langsung. Instrumen yang digunakan dalam penelitian ini yaitu instrumen tes berupa pretes dan postes, yang dianalisis dengan menggunakan uji perbedaan rerata. Hasil penelitian menunjukan bahwa terdapat peningkatan pemahaman matematika antara kelas saintifik dengan reward, kelas saintafik tanpa reward dan kelas kontrol, terdapat perbedaan pemahaman antara kelas saintifik dengan reward dan kelas saintifik tanpa reward, begitu juga ada perbedaan pemahaman antara kelas saintifik tanpa reward dan kelas kontrol.

Abstract

The low students' mathematical critical thinking ability in one of the high schools in Bandung City is a problem that requires teachers to develop and implement innovative learning approaches. Various previous studies have shown that creative learning and encouraging active involvement of students can improve critical thinking skills. This study uses a mixed method with an embedded design type, especially an embedded experimental design model, and adopts a pretest-posttest control group design. The purpose of this study is to examine the effectiveness of the Desmos-assisted Creative Problem Solving (CPS) learning model in improving students' mathematical critical thinking skills. The population of this study is high school students in the city of Bandung, with a purposive sampling technique to select two classes as a sample. The instruments used included mathematical critical thinking ability tests, observation sheets, and interview guidelines. The results of the data analysis showed that the improvement in mathematical critical thinking skills of students who obtained Desmos-assisted CPS learning was higher compared to students in the control class. Therefore, the Desmos-assisted CPS learning model is effectively used in an effort to improve students' mathematical critical thinking skills, especially in social studies classes students, and can be used as an alternative approach to learning mathematics in schools. This research is expected to contribute to the development of mathematics education, especially in the integration of technology with innovative learning models to encourage students' critical thinking skills.

Abstract

Electrical impedance tomography (EIT) supports recent advancements in gastric monitoring for telehealth applications. The challenge in providing low-cost EIT is ensuring a stable current injection over diverse tissue conductivities within the abdominal cavity. Three current source circuits based on Howland's current source are investigated to be applied in a low-cost portable bioimpedance analyzer (p-BIA). Those are: a) triple amplifier Howland current source (TAHCS), b) mirrored Howland current source (MHCS), and c) composite mirrored Howland current source (CMHCS). Evaluation has been conducted based on signal-to-noise ratio (SNR), broadness of the frequency range, and output impedance over frequency value and stability. Due to its high SNR value (82.56 to 102.1 dB), broad (500 Hz to 500 kHz) operating frequency, and consistent output impedance over operating frequency (10 to 25 kΩ), CMHCS is a good option in realizing p-BIA in gastric monitoring based EIT.
