Abstract

This study aims to improve student chemistry learning outcomes by applying the peer-led team learning model. This research design uses Classroom Action Research (CAR) which is divided into two cycles. With four stages, namely planning, action, observation and reflection. This research was carried out at SMA Negeri 1 Tagulandang in class X Science 1, totaling 31 students. This research is only focused on the material of electrolyte and nonelectrolyte solutions. In this study using instruments such as observation sheets, test questions and questionnaires. From the research that has been carried out, it is found that 77.41% of students have successfully met the Minimum Completeness Criteria (KKM) which was continued in the second cycle and obtained an average score of 77.58. From the results of student questionnaires and the results of observations given to students through peer-led team learning, students responded well. This shows that the peer-led team learning model has a positive impact on the learning process.

Abstract

The purpose of this study was to determine the magnitude of the effect of online learning on student learning outcomes in during the COVID-19 pandemic. This research was conducted in class X IPA SMA N 1 Tondano in the 2020/2021 academic year. A total of 25 students of class X IPA 1 were assigned as research samples. This study uses an experimental method with a One-Shot Case Study design. The results of this study consist of two data, namely questionnaire data for assessing student attitudes and post-test as an assessment of student learning outcomes which are then analyzed using correlation regression, and the regression equation obtained was Y = 9.5565 + 0.9073 x. The regression equation shows that the higher the student's attitude score (variable X), the higher the student's (variable Y). From the Product moment correlation test, it is found that the correlation coefficient (rxy) is 0.6599, which proves that the X and Y variables have a strong relationship. To calculate the effect of student attitudes on online learning on learning outcomes, it is calculated through the determinant coefficient formula, and it is found that the magnitude of the influence of student attitudes on online learning on learning outcomes is 43.55%. While the remaining 56.45% is influenced by other variables in the form of distractions and obstacles during online learning.

Abstract

This study uses the Research and Development (R&D) method. The purpose of this research is to develop and determine the quality of powerpoint-assisted learning media. The research subjects were students of class X MIA 3 at SMA Catholic Don Bosco Bitung. The validation test of the four learning media assessment teams obtained 78.5% results, the material assessment team's validation test obtained 79.8% results. The overall results from the validation of the media assessment team and the material assessment team obtained an average result of 79.2% in the valid assessment category. The results of the teacher's response obtained a total score of 44 with an average of 88% included in the very interested category. The results of the first trial of 5 students obtained an average percentage of 36% of students who answered Strongly Agree, 52% of students who answered Agree, 10% of students who answered Disagree, 2% of students who answered Disagree, and 0% Strongly Do not agree. The results of the second trial of 10 students after repairs were made, the average percentage obtained was 67% of students who answered Strongly Agree, 33% of students who answered Agree. Based on the results of the responses of the two groups, it can be concluded that there was an increase in the large group

Abstract

Penelitian ini bertujuan untuk mengetahui kelayakan produk LKS praktikum berbasis pendekatan saintifik dan mengetahui dampaknya pada hasil belajar khususnya materi sifat larutan penyangga dengan melihat seberapa banyak siswa yang mencapai atau melampaui KKM. Jenis penelitian ini adalah penelitian dan pengembangan yang dilakukan di kelas XI IPA 5 SMAN 1 Tondano. Berdasarkan hasil rekapitulasi, LKS praktikum berbasis pendekatan saintifik dinyatakan valid dengan nilai sebesar 83,8%. Dilihat dari respon siswa pada uji coba kelompok kecil dan kelompok besar LKS dinyatakan praktis dengan nilai berturut-turut sebesar 88,17% dan 92,98%. Dampak penggunaan LKS terhadap hasil belajar siswa adalah sebagian besar siswa pada uji coba kelompok kecil dan siswa pada uji coba kelompok besar telah melampaui KKM yang sudah ditetapkan dengan nilai ketuntasan yang diperoleh berturut-turut sebesar 66,67% dan 89,47%. Pengujian hipotesis untuk hasil belajar menggunakan uji t pihak kiri diperoleh nilai thitung(8,517) > ttabel(1,734) yang berarti terima H0 atau tolak H1. Berdasarkan hasil yang diperoleh dapat disimpulkan bahwa LKS praktikum berbasis pendekatan saintifik yang dikembangkan layak digunakan dalam proses pembelajaran.

Abstract

This study aims to determine the effect of the implementation of the Teams Assisted Individualization (TAI) cooperative model with practicum on learning outcomes. This study used an experimental method, with a posttest only control design. The population was students of class X IPA and the sample of class X IPA 2, amounting to 26 people as the experimental class and class X IPA 1, totaling 26 people as the control class. The results of the research were analyzed by using the hypothesis (t-test) and the tcount was 1.778> t table 1.67. From these data, it can be influence the application of the cooperative model type TAI along with practicum on student learning outcomes in chemical bonding material.

Abstract

The purpose of this research is to determine the quality of multiple-choice items in the "Chemistry Boost" test from FMIPAK Unima, based on responses from 80 high school students answering 40 items. The validity test used a combination of Discrimination Index (DI) and Difficulty Level (DL). DI has 6 categories: Very Good, Good Enough, Marginal, Poor Discrimination, Negative, while DL consists of 6 categories: Discarded, Very Easy, Easy, Maintained, Very Difficult, and Reviewed for deficiencies or taught. The results obtained are 23 valid items, or 57.5%. Based on the results, the cognitive processes of Anderson's revised Bloom Taxonomy were determined, with valid items in C1, C2, C3, C4, C5, and C6 being 2, 2, 12, 6, 0, respectively. Items categorized as Higher Order Thinking Skills (HOTS) are in C4 and C5, totaling 18 items. Valid chemistry topics include Acid-Base, Atomic Structure, Stoichiometry, and Reaction Rates. Topics less understood by participants include Compounds and Chemical Formulas, Solubility, Chemical Equilibrium, Ionization Energy, Redox, Electrochemistry, and Hydrocarbons.
