PENGARUH MODEL PEMBELAJAN BLENDED LEARNING TERHADAP PEMAHAMAN KONSEP IPA PADA KELAS IV DI SDN SUDIMAMPIR

The use of time in the learning process today is very important, because it can affect the understanding of students' concepts, one of which is in science subjects. This research is motivated by the lack of available learning time which is often insufficient to convey the entire learning material, this affects the understanding of science concepts, so it is not fulfilled. On this basis, researchers try and teach science subjects, especially the material properties of sound by using a blended learning model that can be collaborated between face-to-face learning directly and online. So that in this study the formulation of the problem, namely: 1) How is the application of the blended learning learning model to understanding the science concept in class IV at SDN Sudimampir, 2) How is the effect of the blended learning learning model on understanding the science concept after learning using the blended learning model is implemented. This research was carried out at SDN Sudimampir for the 2021/2022 academic year with a research sample of 12 students. The form of the test used is a description test with a total of 10 questions. This research method uses Pre-Experimental Design with One group pretest-posttest research design. The results showed (1) The test was carried out 2 times, the data was collected through a pretest and then given treatment using a blended learning learning model, then a final test (posttest) was carried out and then analyzed using the normality test, homogeneity test, t-test and N-Gain. (2) The results show that the average pretest carried out is 61.11 and for the posttest average is 80.22. After being treated using a blended learning learning model on understanding science concepts, there is a significant effect that can be seen from the N-Gain result of 0.7277 which is included in the high category, this is also supported by the t test results which show the comparison of pretest and posttest results obtained through test results. t with a significance value of 0.000. Based on the test criteria, if the significance value is < 0.05, then H_0 is rejected and H_1 is accepted because there is an effect of the blended learning model on understanding science concepts which is stated to be better than before using the blended learning model because 0.000 <0.05. Thus, learners using the blended learning model have a significant effect on understanding science concepts at SDN Sudimampir.

Effectiveness of Discovery Learning Model Based on Team Games Tournament Assisted with Thematic English Media on Learning Achievement

Learning achievement in learning is very important because the success of learning carried out in teaching and learning activities can be seen from student learning outcomes. Learning achievement is the result achieved by students or someone after carrying out learning activities. Thematic learning achievements at SD N 1 Patukangan class IV in 2018/2019 still vary widely. Not all students' Thematic learning outcomes are high or good. There are several Thematic learning achievements that are unsatisfactory. The purpose of this study was to determine the effectiveness of using the discovery learning model based on team games tournaments assisted by thematic workshop media on student achievement in class IV SD N 1 Patukangan. The method used in this study was a quasi-experimental method with a research design using Nonequivalent [Pre-Test and Post-Test] Control Groups Design (NCGD). The results showed that the experimental class mean was 82.50, while the control class showed a result of 71.09. This shown that the average learning achievement of students in the experimental class is higher than the average learning achievement of students in the control class. The n-gain results in the experimental class show moderate criteria with an average gain of 0.45 while those in the control class show moderate criteria with an average of 0.30. This shows that there is the effectiveness of the discovery learning model based on team games tournament assisted by thematic workshop media on student achievement.

Improving Early Childhood Emotional Intelligence Through Traditional "Balogo" Games in Kindergartens

Emotional intelligence is a determinant of individual success. However, today's emotional intelligence is fading. Early childhood is the foundation for the development of individual potential and intelligence. Thus, the urgency needs to be taken special action. The focus of this research is to improve the emotional intelligence of early childhood through the traditional game "Balogo". This research was conducted at Dharma Bahagia Kindergarten, Samarinda through an experimental design. The average N-Gain result in the experimental class in this study was 76% which was categorized as a high level, and the category of effectiveness level included in the effective or increasing category. This means that the treatment of traditional Balogo games has a fairly effective effect on improving early childhood emotional intelligence. Meanwhile, the average N-Gain result in the experimental class in this study was 16% which was categorized as low level, and the foe category of effectiveness level included in the ineffective/not increasing category. This means that if children are not given any treatment (control) it will not increase emotional intelligence based on the results of the pretest and posttest in early childhood.

The Effect of Research-based Digital Module towards Students' Science Literacy Ability in Static Fluid Materials

The main problem of this study is the implementation of physics learning activities that do not involve the scientific process that can train students' science literacy ability, especially in the competence aspects. As a result, the development of students' science literacy ability is not maximal. A solution given in this study is a research-based digital module as teaching material. This study was conducted at SMA Dharma Karya UT with a quasi-experimental method and nonequivalent control group design. The study used purposive sampling to decide the study's sample with the following classification XI IPA 2 as the experimental class with 25 samples and XI IPA 1 as the controlled class with 25 samples. The instruments of the study were test and non-test. The science literacy test contained ten questions, and the non-test was a questionnaire. In addition, based on a statistical calculation of the post-test by using a nonparametric test, Mann-Whitney showed that a significant score 2-tailed (0.011) < significant level (α=0.05). It showed a research-based digital module's effect on students' science literacy ability. Meanwhile, the result of N-Gain showed the enhancement of students' science literacy ability; this can be seen from the superior N-Gain value in the experimental class. Moreover, the questionnaire also showed that using research-based digital modules for students' science literacy ability was good (73%).
