This research used descriptive method with qualitative approach because it is relevant from the initial process to the final product, and research instrument used is in the form of interview sheet. The sample of this research is 68 third grade students of Mathematics Education Study Program of Faculty of Teaching and Educational Sciences, University of Swadaya Gunung Jati Cirebon. The study was conducted in the period of March - July 2016. Based on the results of this study it can be concluded that students' learning difficulties during the implementation of Project Based Learning caused by internal factors, that is lack of motivation, which can be seen from the lack of students in reading and looking for various references related to the material, they rely on one reference book only that used during lectures. This resulted to the lack of understanding in learning the Evaluation Instruments’ Quality which can be seen from the difficulty in classifying evaluation test questions based on Bloom's Taxonomy and arranging scoring guidelines, using validity formula, reliability, item discrimination, and index of difficulty to determine instrument quality, and difficulty in accomplishing the final product.","PeriodicalId":31356,"journal":{"name":"Kalamatika","volume":"3 1","pages":"51-62"},"PeriodicalIF":0.0,"publicationDate":"2018-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43985914","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}

So it needs a study to facilitate the students to be active, interesting and challenging for students to think and therefore contributes to the students ability to represent, understand the material during learning process and solve mathematical problems. Quantum learning model puts students on comfortable and pleasant condition so that students can play an active role in the learning process and student expected to get the flexibility to bring their own representation and easy to solve the problem. The main objective of this study was to determine the improvement in the mathematical problem solving and multiple representation of students who obtain quantum learning model and students who received conventional learning, as well as to determine the relationship between the mathematical problem solving and multiple representations. This research is a quasi experimental with non equivalent control group design. The population of this study are all students of class VII with two classes of them as samples. The research data obtained through problem-solving ability and multiple mathematical representations test. The results showed that: (a).
