Abstract

Educators need to innovate in learning by utilizing one of the technology-based learning media using the right learning model so that the learning process becomes effective and meaningful. The purpose of this research was to develop a flipbook learning media hybrid model in basic chemistry practicum learning in improving students' science process skills. This type of research was research and development with the model proposed by Borg & Gall using the 4D model. Material and media expert validation was used to assess the feasibility of the media. The practicality and effectiveness of the media were tested in small groups. The research instrument consisted of observation sheets, practicum reports and questionnaires. The data consists of qualitative and quantitative where collected using a concurrent or concurrent model. Quantitative data was processed into percentages and interpreted to be the level of feasibility and the level of practicality of the media. Effectiveness is a media capability that is developed to support the improvement of students' science process skills. Qualitative data describes students' science process skills that were observed while students are participating in media trials. Based on the research results obtained, it can be concluded that flipbook learning media with a hybrid model in basic chemistry practicum learning that has been developed is very feasible and practical to use in basic chemistry practicum learning and can be used to train students' science process skills independently or in a supervised manner.

Abstract

Good teaching materials have certain criteria or certain standards, such as their relevance to the current curriculum. The STEM approach offers teachers the opportunity to introduce students to various concepts to teach teaching materials that can be integrated into natural sciences including chemistry. This research aims to describe the presentation of STEM aspects in class XI high school chemistry teaching materials regarding reaction rates. The method in this research is a qualitative descriptive method with a content analysis approach. The data source comes from three books for class XI high school chemistry teaching materials which are most widely used in Pematangsiatar City. The technique for selecting research objects uses purposive sampling technique. Data collection was carried out analyzing material based on STEM indicators. Testing the validity of the instrument uses the Gregory formula, while testing the validity of the data uses data triangulation. The results of the research show that the percentage of quotations appearing in each book, namely in book A, has aspects of Science 30%, Technology 40%, and Mathematics 30%. In book B, the Science aspect is 19.05%, Technology 42.86%, Engineering 9.52% and Mathematics 28.57%. In book C, the Science aspect is 25%, Technology 25%, Engineering 18.75% and Mathematics 31.25%. Based on the total occurrence of STEM aspect indicators, the order of teaching materials that fulfill the STEM aspect is Book B > Book C > Book A, so that Book B has the highest number of occurrences of STEM aspect quotes.

Abstract

Many high school students consider chemistry to be a difficult subject. Most students still have difficulty understanding chemical concepts comprehensively, but the obstacles they experience have not been fully identified by teachers. Chemistry is one of the subjects that is less favored by students, because science, especially chemistry, is studied abstract things. Students' difficulties in learning chemistry result in many students experiencing failure in learning chemistry material. This study aims to describe and explain various learning difficulties and the factors causing difficulties in learning chemistry experienced by high school students. This study involved 44 students from all grades XII MIA and one chemistry teacher as the subjects. This study used a phenomenological research type with a qualitative approach. The data collection process was carried out using document study methods, observation, questionnaires, and interviews. Based on the results of the study, the level of student learning difficulties is categorized as slightly difficult (43%), quite difficult (48%), and difficult (9%). Internal factors that cause learning difficulties include a lack of understanding of chemistry material, low mathematical ability, and minimal motivation in learning chemistry. External factors that influence learning difficulties include the teacher's teaching methods, the negative impact of socializing with peers, and less conducive learning situations and times.

Abstract

This study aimed to investigate the effect of applying the Project Based Learning (PjBL) model assisted by animated videos on students’ learning outcomes in atomic structure material at Grade X of SMA Negeri 3 Pematangsiantar. The research employed a quasi-experimental design with a pretest-posttest control group. The participants consisted of two classes: the experimental class, which received instruction using PjBL assisted by animated videos, and the control class, which received conventional instruction. The research instrument was a learning achievement test administered before and after the treatment. Data were analyzed using a t-test and N-Gain calculation. The results indicated that the average pretest scores of both classes were relatively the same. After the learning intervention, the average posttest score of the experimental class increased significantly compared to the control class. The average N-Gain score of the experimental class was in the medium/high category, while that of the control class was in the low/medium category. The t-test result showed a significance value of p < 0.05, indicating a significant difference between the two classes. It can be concluded that the implementation of the Project Based Learning model assisted by animated videos has a positive effect on improving students’ learning outcomes in atomic structure material.

Abstract

The purpose of this study was to determine the effectiveness of the Problem-Based Learning model assisted by Canva on the understanding of colloid system concepts among 11th grade students at SMAN 1 Girsang Sipanganbolon using an experimental research method with a quasi-experimental design. Data collection techniques used a multiple-choice test validated by expert validators, with instruments consisting of problem-solving ability test questions. The research subjects were 60 students from Grade XI Science Class 2 and Grade XI Science Class 4. Data analysis techniques included normality tests, homogeneity tests, and hypothesis testing using the paired sample t-test.The results obtained in this study indicate an improvement in the learning outcomes of grade XI students at SMAN 1 Girsang Sipanganbolon, particularly in the subject matter of colloid systems. This improvement in learning outcomes can be seen from the average pretest score of 49.67 and the average posttest score of 84.67 in the experimental class. These scores indicate a significant improvement in student learning outcomes. The homogeneity test was conducted, and the significance value obtained was greater than 0.05 (> 0.05), thus meeting the criterion where the sample is homogeneous. In the paired sample t-test, the t-value obtained was 18.542, which is greater than the t-table value of 1.699, and the sig (two-tailed) was 0.000, which is smaller than the α value (0.05), thus concluding that the problem-based learning model assisted by Canva is effective in improving students' understanding of colloid systems in grade XI at SMAN 1 Girsang Sipanganbolon.

Abstract

This study aims to determine the effect of the Guided Discovery Learning model on the creative thinking skills of Class X students in the topic of atomic structure at SMA Negeri 6 Pematangsiantar. The research method used was a quasi-experimental design by comparing an experimental class with a control class. The results showed an improvement in students’ creative thinking skills in the experimental class. This can be seen from the increase in the average pre-test score of 81.25 to the post-test average score of 87.47. Hypothesis testing also supports this finding, where the tcount value of 3.879 is greater than the ttable value of 1.699, and the significance value (2-tailed) of 0.000 is smaller than α (0.05). Therefore, it can be concluded that the Guided Discovery Learning model has a significant effect on students’ creative thinking skills in Class X on the topic of atomic structure.
