Science Learning with The Qur'an and Hadith Through Audiovisual Media (Video) to Improve Concept Mastery and Religious Attitude
Get PDFThis study aims to improve students' concept mastery and religious attitudes in science learning with the Quran and Hadith contents through audiovisual media (video). The research design was quasi-experimental, with experimental and control classes as the research subjects. Data were collected using a test to measure students' concept mastery and religious attitudes with 30 questions, an observation sheet, and a questionnaire with 22 questions. The measurement results of the two test forms were analyzed in N-Gain, while the observation sheets were analyzed descriptively. Students' responses were analyzed in percentage. The results showed that students who learned using the Qur'an and Hadith content through the media were much better than through non-media learning. The N-Gain score for concept mastery was 50.77% (medium) and 38.56% (medium), while for religious attitude was 3.25 (good) and 3.61 (very good). This study proves that the implementation of science learning with the content of the Qur'an and Hadith in teaching and learning activities is quite good, and students' responses to the learning implementation are quite high
Improving Student's Skills and Concept Understanding in Vibration and Waves with the Use of Visual Media Concepts on Students
Get PDFThis research was conducted to determine the effectiveness of the media in improving science process skills. The effectiveness of visual media was further investigated using the Quasi-Experimental method with a pre-post test control group design. Learning is carried out using a cooperative model of investigative group type. The population is all students of class VIII of one junior high school in West Java academic as many as 324 students. This study aims to develop GI type cooperative learning to improve students' process skills and concept mastery. Science was compiled using cooperative learning with group investigation, but non-visual media in the control class. The results showed that visual media can improve science process skills and mastery of vibration and wave material concepts. It can be seen that the N-Gain value is 55% for science process skills (medium category) and 67% (medium category) for concept mastery. Conclusion of the research can be seen that the use of visual media material vibrations and waves in cooperative learning investigative group type can improve skills, mastery of concepts and motivate students to be active in learning compared with investigative group type cooperative learning without the use of visual media
Bibliometric Mapping Analysis of Scientific Publications in Chemistry Field on Cerium Oxide Nanoparticles Using Vosviewer
Get PDFThis study aims to look at the advancement of scientific publications related to cerium oxide nanoparticles through a bibliometric approach using qualitative methods with descriptive statistics on literature studies on scientific articles. Two types of software are used: Publish or Perish and VOSviewer. Publish or Perish is used as a source to search for various relevant articles through the Google Scholar database, using the keyword "Cerium Oxide Nanoparticle," and obtained 997 articles from 2012 to 2022. The results show that 2012 and 2013 were fairly constant, increasing from 2014 to 2016, fluctuating from 2017 to 2020, and decreasing in 2021 and 2022. Data from Publish or Perish is inputted into VOSviewer to visualize and analyze mapping trends related to cerium oxide nanoparticles, obtaining 7 clusters of 189 items. The popularity of the terms used in scientific publications related to cerium oxide nanoparticles during the last three years has become less trending. This study concludes that there are still opportunities for future researchers to develop or even make discoveries related to cerium oxide nanoparticles

From the analysis of teacher observations in cycle 1 of the medium category and cycle 2 of the high category. Meanwhile, from the analysis of student activities in cycle 1 for aspects of interest, attention, participation, and presentation in the moderate category and cycle 2 in all these aspects in the high category Based on the research, it can concluded that there is an increase in science learning outcomes in water purification material with the Science, Technology, Engineering and Mathematical, (STEM) approach in class IX students of SMP
Webbed Type of Integrated Science Learning on the Theme of Environmental Pollution to Improve Students Scientific Literacy
Get PDFThis study aims to get information on how to integrate the science learning type of Webbed with the theme of environmental pollution to improve students scientific literacy. The subject of study was seventh-grade students in middle school. The research method used in this study is a quasi-experimental method with a Nonequivalent Control Group Design. The data were analyzed by calculating the normalized gain average score to determine the increase in scientific literacy. The average result of N-Gain in students' scientific literacy as a whole obtained in the experiment class is 0.66 while the control class is 0.43, both are in the medium category with a difference of 0.23. The hypothesis test result in the t-test is known as the significance level of 0.000 which means that Ho is rejected, and Ha is accepted. Based on the result of this t-test, it is known that students scientific literacy abilities are not the same. This means that there were differences in the increase in scientific literacy in integrated webbed versus conventional science learning types without integration. The result of the study shows that webbed-type integrated learning can improve students scientific literacy on aspects of content, process, and attitude

Abstract Guided Inquiry Learning with Mind Mapping and Concept Map to Increase Concept Mastery and Student Learning Motivation
Get PDFThis study aims to measure students' conceptual mastery and motivation in learning the respiratory system. The study was conducted on class VIII SMPN 1 Klapanunggal students in 2017/2018. The learning used in this study was through guided inquiry learning with mind mapping with pretest posttest control group design. The use of this research design involves two classes as research samples, one experimental class and one control class. The selection of these two classes is done by taking subjects not based on strata, random or regional but based on certain goals. The research subjects were divided into two groups, namely the experimental group and the experimental group. control. The experimental group received Guided Inquiry learning with mind mapping, while the control group was the group that received Guided Inquiry learning with concept maps. The results of mastery of the concept of the experimental class and control class each obtained an average gain of 6.09 and 5.78, the average pretest score of the experimental class students was 51.9 and the control class students were 44.7 from the ideal score. This shows that the average pretest score of the two classes is not much different. It can be concluded that the average N-gain in the control class is 36.9% in the medium category, while in the experimental class the average N-gain is 43.7% in the medium category
Imtaq-Based Solar System Learning in Improving Mastery of Concepts and Religious Attitude Towards Madrasah Tsanawiyah Students
Get PDFThis experiment research aims to measure the mastery of students concepts and religious attitude on solar system learning based on IMTAQ. The research was conducted on class VIII MTsN 22 Jakarta in 2017/2018. The model used in this research is a Problem Base Learning with the research design of pretest posttest control group design. The use of this research design involves two classes as research samples, one experiment class and one control class. The selection of these two classes is done by taking the subject not based on strata, random or regional but based on certain goals. The research subjects were divided into two groups, namely the experiment group and the control group. The experiment grup get Problem Base Learning model based on IMTAQ, while the control grup just get a Problem Base Learning model. The result of mastery of the concept of the experiment and control class each obtained an average gain of 49.7 and 43.7. This shows that the average pretest score of the two classes is not much different. Increasing the mastery of concepts and religious attitudes of MTsN students on the solar system material can be concluded that the average N-gain in the control class is 0.44% in the medium category, while in the experimental class the average N-gain is 0.50% in the medium category
