The population in this study was 20 grade IX students of SMP Negeri 2 Cimahi who were used as a sample, consisting of 10 male students and 10 female students who were randomly selected. The instrument used in this study is to provide four mathematical creative thinking questions consisting of indicators of fluency, flexibility, originality, and elaboration. The data in this study were analyzed using the value of the percentage of students who had done mathematical creative thinking problems that had been given and then compared based on gender. The results of the research that has been conducted revealed that overall, the ability of female students to think creatively mathematically is valued higher than the ability of male students to think creatively mathematically. This can be seen in terms of the proportion of overall value or certain aspects. Regarding fluency, male students score higher than female students, while female students score higher on flexibility, originality, and elaboration. It can be concluded that gender can affect students' ability to creative mathematical thinking skills.","PeriodicalId":505133,"journal":{"name":"(JIML) JOURNAL OF INNOVATIVE MATHEMATICS LEARNING","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140249726","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}

Especially mathematics learning, which tends to require more effort to deliver material. Post-pandemic learning causes didactical obstacles to student and teacher learning during the teaching and learning process. So the purpose of this study is to analyze student barriers to post-pandemic learning. The research method used in this study is qualitative-descriptive, with data collection techniques such as survey methods, observation results, questionnaires, and interviews. The object of this study was 19 grade VIII–4 students and senior teachers at SMP Negeri 1 Cihampelas. This research uses several instruments for students, and the results can be analyzed for obstacles to the post-pandemic learning process. Based on the results of the study, it shows that post-pandemic learning barriers for Grade VIII–4 students are adaptation to a new environment; understanding the material is more difficult and ineffective because the learning process does not involve technology, conventional learning methods, psychological changes, or habits when online learning is still carried over so that it affects face-to-face learning, where students are not ready to get the next material due to the material they previously did not understand due to the lack of maximum understanding of students when learning online. Not only students, but teachers also have their own obstacles when learning after this pandemic, so teachers also need time to be able to adapt to face-to-face meetings that run according to mutual expectations.","PeriodicalId":505133,"journal":{"name":"(JIML) JOURNAL OF INNOVATIVE MATHEMATICS LEARNING","volume":"67 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140248444","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}

The purpose of this study is to determine the success of applying Kahoot media in improving the ability to understand mathematics in integer material for junior high school students. The method used in this research is quantitative. The data collection technique comes from the results of a description test of 4 questions regarding students' mathematical understanding abilities in integer material. Quantitative data analysis techniques were processed using descriptive and inferential statistics using Microsoft Excel and SPSS applications. This research was conducted on students at one of the MTs in West Bandung class VII as many as 22 students. The results showed that there was an increase in students' mathematical understanding abilities as indicated by the learning outcomes and student responses after the learning process took place. Students can develop their mathematical understanding skills with the help of this Kahoot media. This increase can be proven by the increase in students' pre-test and post-test results as evidenced by the calculation of the n-gain value. The results of the n-gain calculation show that the increase in students is 0.83 in the high category.

Using the literature search method, this research was carried out by analyzing a range of types of information in qualitative and quantitative data from various texts based on previous studies. The literature exploration system uses a variety of references similar to books, exploration journals, and distance literacy operation modules that analyze studentsâ€™ mathematical problem-solving skills. The results of this study validate that distance learning can affect studentsâ€™ mathematical problem-solving skills when teachers use innovative methods and interactive learning media. In fact, students can develop their mathematical problem-solving skills through meaningful learning. This means that students can build their own knowledge with learning that requires independent study on the part of students so that they can construct conceptual discoveries from the material being taught. Students' mathematical problem-solving skills can also be affected by the active role played by students in distance learning. For this purpose, it is necessary for educational institutions to apply appropriate methods of learning and media that allow students to have an active role in the educational process. In addition, educational institutions must strive to provide effective and efficient communication, mentoring, and support services to students and parents.","PeriodicalId":505133,"journal":{"name":"(JIML) JOURNAL OF INNOVATIVE MATHEMATICS LEARNING","volume":"39 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140250265","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}
