Abstract

This study aims to (1) find out whether the increase in student learning outcomes with the application of cooperative-based e-modules of the NHT type is higher than the learning of NHT chemistry with student reference teaching materials. (2) find out whether there is an effect of the application of e-modules based on cooperative types of chemistry. NHT on student learning outcomes. This research was carried out at the Harapan Baru Private High School Medan in November-December 2021. From the results of the study, the average pretest score for the experimental class was 36 and the control was 28,167. While the posttest average value of the experimental class was 82,667 and the control class was 77.5. The chemical normalized N-Gain value of the experimental class students was higher than the control class, namely 0.7254> 0.685 or based on the N-Gain percentage, which was 72.54% for the experimental class and 68.5% for the control class. The difference from the increase in learning outcomes from the two classes, namely 4.09%, it can be said that the application of the NHT cooperative-based chemistry e-module with student reference learning media on chemistry. In the hypothesis test, namely the t-test of one party (right side) at a significance level of 0.05, it is obtained that t_count > t_table which is 3,004> 2,002 then Ha is accepted and Ho is rejected. Thus, it can be said that there is an effect of applying cooperative-based chemistry e-modules on student chemistry learning outcomes in chemistry.

Abstract

Inappropriate teaching methods can cause student learning outcomes and interest in science subjects. Especially if the material is delivered in ways that are less interesting. One teaching method that is believed to improve learning outcomes is the experimental method. This study aims to describe the knowledge of teachers' understanding of the experimental method, the use of media, and the classroom atmosphere with the experimental method. The research method used is library research with a descriptive qualitative approach. Descriptive data was collected through written or spoken words from teachers and students observed. Relevant reading materials were selected from the library, such as books, dictionaries, journals, documents, and magazines. The criteria for selecting reading materials include novelty and relevance to the research. The results showed that the teacher was maximized in applying the experimental method on the properties of light, in accordance with the concept of knowledge about the experimental method. Thus, it can be concluded that the application of the experimental method has been optimal, allowing teachers to effectively describe the properties of light in learning at the elementary school level.

Abstract

This study aims to analyze the influence of principal's leadership and teacher competence on teacher performance at Cluster II State Elementary Schools, Tanjungsasri District, Sumedang Regency. The research method uses a quantitative approach. The population is all Cluster II State Elementary Schools, Tanjungsari District, Sumedang Regency with 105 teachers. Data collection techniques using a questionnaire through the distribution of questionnaires. Analysis of research results using descriptive statistics, correlation and simple and multiple regression using SPSS. The results of the study prove that: 1) there is an influence of principal's leadership on teacher performance in Cluster II SDN throughout Tanjungsari District, Sumedang Regency. The magnitude of the influence of principal's leadership on teacher performance is 43.2%, the remaining 56.80% is determined by other variables; 2) there is an effect of teacher competence on teacher performance in Cluster II SDN in Tanjungsari District, Sumedang Regency, the magnitude of the influence of teacher competence on teacher performance is 52.10%, the remaining 47.90% is determined by other variables; and 3) there is an effect of principal leadership and teacher competence on teacher performance together of 75.9%, this means that principal leadership and teacher competence together can affect teacher performance in Cluster II throughout Tanjungsari District, District Sumedang is 75.9% and the remaining 24.10% is determined by other variables that are not examined.

Abstract

Problem Based Learning (PBL) learning model is a set of learning activities that emphasize the process of solving problems faced scientifically. The use of video media can help students' learning process and will have a big impact on the learning outcomes of thermochemical material because almost everyone, from children to the elderly, now has a smartphone. In addition to learning videos, powerpoint is one of the learning media that can help students who have learning difficulties. The purpose of this study was to investigate whether the thermochemistry learning outcomes taught using PBL-based learning videos were higher than the thermochemistry learning outcomes taught using PBL- based PPT. This study involved the experimental class I and the experimental class II. From the results of the study, the average pre-test for the experimental class I was 41,95 and the experimental class II was 41.44. After being treated with learning in both experimental classes, post-test was then recommended to determine learning outcomes, the post-test average of experimental class I was 83.14 and experimental class II was 78.44. The results showed that the experimental class I which was taught by learning video media and the PBL model was higher than the learning outcomes of the experimental class II which was taught by the powerpoint media and the PBL model. It can be concluded that the use of instructional video media, learning outcomes are higher than the use of powerpoint media.

Abstract

This research aims to (1) analyze chemistry teaching materials on reaction rates used in schools according to BSNP standards; (2) describe the feasibility of integrated problem-based learning module teaching materials on reaction rate material based on BSNP criteria; and (3) know student learning outcomes after being given teaching materials for the integrated problem-based learning module on reaction rate material. This research uses the R&D method with the ADDIE model, which includes stages (analysis, design, development, implementation, and evaluation). The product developed was validated by four expert validators, consisting of two chemistry lecturers and two chemistry teachers. From the research results, it was found that the analyzed teaching materials were suitable in terms of content, presentation, contextual, graphic, and language, in accordance with the feasibility aspects of BSNP. Students show a high level of interest in the developed module based on the presentation assessment. Then, student learning outcomes using integrated problem-based learning module teaching materials on reaction rate material based on data processing are capable and effective in improving student learning outcomes.

Abstract

This study aims to analyze the effect of developing discovery-learning-based module teaching materials on reaction rate material. This type of research is called research and development (R&D). The sampling technique used was random sampling. The sample used is one class, namely class XI MIA 2, as an experimental class. The research instruments used in this study were both test instruments and non-test instruments. After obtaining the research data, the prerequisite tests were carried out, namely the normality test and the homogeneity test, finally making a decision. The discovery-based chemistry learning module on reaction rate material has been proven to be in accordance with BSNP. This module has also been effective in improving student learning outcomes, indicating a significant increase in understanding. In addition, at the limited dissemination stage, this module received very high ratings in various aspects, indicating great benefits for students in understanding chemistry materials on reaction rates. Thus, it can be concluded that there is an effect of developing discovery-learning-based module teaching materials on reaction rate material.
