The method used in this research was a descriptive method. The subject of this research is experts and students. Experts chosen in this research are one science expert, one media expert, and one science teacher. Students chosen in this research are fifty-seven students in 9 grade at one of junior high school. The gamification aspects were chosen to make the game were goals, science content, and challenging environment. The expert gave feedbacks in both media and the quality of the content aspects. Students were asked about their agreement level of the gamification elements and the effect of gamification. The effect of gamification asked were motivation, joyness, convenience, addiction, understanding improvement, attractiveness, and interactiveness. The result found that experts gave a good score towards this game. Students also agreed that the game has goals, science content, and challenging environment. The result also found that the gamification elements itself caused them to feel motivated, joy, convenience, addiction, improve their understanding, and attracted after playing the game. Other than that, students confirmed they have two ways of interaction with the game. More than half of total students got a score higher than the average score after playing the game.","PeriodicalId":30901,"journal":{"name":"Jurnal Inovasi Pendidikan IPA","volume":"6 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2020-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45064989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the experimental group consisted of male students using learning with the MI and the control group consisted of female students using learning with the MI approach. Analysis of data obtained from this study, using the Independent Sample t-test and Pearson Product Moment Correlation Coefficient. The findings of this study indicate that there is a statistically significant difference between the ability of MI in the experimental group and the control group, where the average score experimental group is higher. These results can be seen in the average score of MI ability in the experimental group is higher in visual-spatial, music, logical-mathematical, interpersonal and bodily-kinesthetic intelligence.

Students' perceptions of learning have an important role to detect the quality of learning. Thus, this study aims to determine the factors of student perception of natural science learning and the differences between the two countries based on these factors. The sample in this study were 5870 Indonesian students and 5272 Singaporean students who took the 2015 PISA survey. The research data were the results of the PISA survey (codes ST098, ST100, ST103, and ST104) regarding student perception of natural science learning. The data analysis technique used is Principal Component Analysis to detect factors and Discriminant Analysis to show differences between the two countries. Students' perceptions of science learning in Singapore and Indonesia can be classified into five factors: Practicum, Assistant, Explorative, Counseling, and Collaborative. Based on these factors, there are differences in the perception of the implementation of science learning between Indonesian and Singaporean students. Indonesian students tend to be stronger in defining that science learning is full of exploration, collaboration, and teachers play the role of counselor very well, while Singapore students feel more than practical learning based on science and teachers provide student assistance in dealing with difficulties in the learning process.","PeriodicalId":30901,"journal":{"name":"Jurnal Inovasi Pendidikan IPA","volume":"6 1","pages":"79-87"},"PeriodicalIF":0.0,"publicationDate":"2020-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43990062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such investigative activity, or investigation in general, serves as the basis for a researcher to develop his or her study. In relation to this initiative, the ICT-based learning capacity becomes a significant part since this capacity serves as the basis for the utilization of the Web-Based Inquiry, which has been marked by the capacity of operating the overall investigation information from the ICT-based learning. Departing from this elaboration, the objective of the study is to describe the capacity of ICT information and the delivery of the preliminary information for the needs of the Web-Based Inquiry. During the conduct of the study, the purposive sampling technique was implemented in order to define the number of the sample. As a result, 66 students from Batch 2019 of Lampung University were selected as the subjects for the study. Then, the data gathering instrument that had been implemented was the investigation (ICT-Based Learning) questionnaire. The data that had been gathered then were descriptively analysed. The results of the study show that the biggest data portion has been found in the use of the Internet-accessing tool although the score of this biggest portion falls into the “Low” category (under 25%).
