Abstract

The problem with tablet pens is only done during online learning. For this reason, pen tablets can be used in offline/face-to-face learning with the help of a projector. Not only that, this research also uses the YouTube application to upload recorded classroom learning so that it can be accessed by many people, especially students taking basic analytical chemistry classes. The aim of this research is to determine the effectiveness of using pen tablets in learning basic analytical chemistry courses in the digital era after the pandemic with offline/face-to-face learning and using the YouTube application to help students repeat basic analytical chemistry lessons so as to improve student learning outcomes. The research method in this study is descriptive qualitative and quantitative methods. Student interest according to the questionnaire has an average score of 3.78 in the good category and there is an increase in learning outcomes so that the effectiveness is 79%.

Abstract

This research or study aims to determine the effect of the Guided Note Taking Learning Model Using Macromedia Flash 8 on Student Chemistry Learning Outcomes on the Periodic System of Elements for Class X at SMA Kampus Nommensen Pematangsiantar. This type of research is experimental research using a pre-test and post-test research design. The population of this study was all class X of SMA Swasta Kampus Nommensen Pematangsiantar consisting of 3 classes. The sample taken was a random sampling technique. The sample in this study was students in class X - 1 as the experimental class and students in class X - 3 as the control class. Data on learning outcomes can be collected using an instrument in the form of an objective test in the form of multiple choice consisting of 25 questions. Furthermore, the data analyzed by testing the research hypothesis using the independent sample t-test using SPSS 24 was obtained based on the results of the hypothesis test data from learning outcomes with sig (2tailed) of 0.000 < 0.005, then H0 can be rejected and Ha accepted. And there is also data analyzed using the N-Gain test from learning outcomes showing an average value in the experimental class of 73% while the average value in the control class was 43%. This means that there is a significant difference in the guided note taking learning model using macromedia flash 8 on students' chemistry learning outcomes in the periodic system of elements material in class X of SMA Swasta Kampus Nommensen Pematang Siantar in the 2024/2025 Academic Year.

Abstract

Penelitian ini bertujuan untuk mengetahui: (1) ada tidaknya perbedaan yang signifikan anatar pemahaman konsep kimia pada pendekatan chemo-entrepreneurship melalui metode inkuiri bebas; (2) ada tidaknya pengaruh kemampuan pemahaman konsep kimia yang diajarkan dengan pendekatan chemo-entrepreneurship melalui metode inkuiri bebas. Jenis penelitian ini adalah penelitian kuantitatif dengan pendekatan eksperimen semu atau quasi eksperimen, Instrumen penelitian ini menggunkan tes tertulis dengan bentuk tes essay sebanyak 10 soal. Teknik analisis dilakukan dengan membandingkan hasil tes kelas kontrol dengan kelas eksperimen. Pengujian hipotesis yang dilakukan adalah uji-t pihak kanan dengan α = 0,05 dan dk= n-1. Hasil penelitian ini dapat disimpulkan bahwa melalui pendekatan chemo-entrepreneurship melalui metode inkuiri bebas dapat mengingkatkan pemahaman konsep kimia mahasiswa. Berdasarkan hasil uji hipotesis kedua maka dapat dikatakan bahwa terdapat pengaruh kemampuan pemahaman konsep kimia yang diajarkan dengan pendekatan chemo-entrepreneurship melalui metode inkuiri bebas. Kesimpulannya adalah terdapat pemahaman konsep kimia menggunkan pendekatan chemo-entrepreneurship melalui metode inkuiri bebas dari pada pembelajaran konvesional.
