This process is obtained through teacher innovation which provides learning with various methods and approaches that align with what will be taught. Inductive-deductive is an approach that can help students' creative thinking processes and increase learning motivation. For this reason, this study wanted to see how effective and influential this approach is on the ability to think creatively and motivation to learn. The method used is a significant test using one sample t-test and one paired sample t-test. The results obtained are tcount values of 2.09 and 10.66 for the inductive-deductive class and -0.848 and -0.94 for the conventional class where the ttable value is 1.684. Whereas to see the effect of the approach obtained values of 6.149 and 6.344 with a ttable of 1.960. The value that is greater than the ttable states that the class is effective and has influence, so it can be concluded that the inductive-deductive approach is effective for critical thinking skills and learning motivation, while conventional classes are not used effectively. The inductive-deductive approach also influences students' creative thinking abilities and learning motivation.","PeriodicalId":300356,"journal":{"name":"Paradikma: Jurnal Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127753383","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}

Yesterday is a memory, today is a reality and tomorrow is a hope. Who would have thought that the corona virus would become one of the elements forming a new life cycle not only for Indonesia but for the whole world. During the Covid-19 pandemic, Large-Scale Social Restrictions (PSBB) were implemented, this had an impact on the implementation of face-to-face (online) learning. Educational institutions must also change direction. Work from home. Going online is one way to stay afloat. Learners at all levels, learn online. Some are still not familiar with this method, especially those in regions or villages, so that in its implementation there are obstacles that result in the implementation of the learning process not being optimal. Those who live in cities experience different obstacles again. Learning that should be carried out face-to-face has changed to online. One of the differences that exist is seen from progress, namely those who live in cities and in villages have different difficulties. Not to mention the other variants. This article aims to find out the obstacles experienced by students during the implementation of online learning in Mathematics lessons. The approach used is a phenomenological approach. How does the exploration of phenomenology play a role in the mathematical approach. The hope is that with this approach you can get information regarding the implementation of the online learning process for learning Mathematics during the Covid-19 pandemic. Exploration of Mathematics Education is seen from a phenomenological attitude, which means that it starts with entering phenomena through practice. The exercises provided are designed so that participants are able to illustrate, mention, give directions and are able to associate meanings and differences. Actually someone gets something in learning more than one's intentions, it doesn't even matter whether a teacher teaches well. For this reason, a creative teaching method is needed in learning mathematics so that there is good interaction between students and teachers. Conclusion: The process of learning mathematics online was not optimal during the pandemic due to several factors that affected the smooth implementation of learning.","PeriodicalId":300356,"journal":{"name":"Paradikma: Jurnal Pendidikan Matematika","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125452317","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}
