The purpose of this study was to know the learning difficulties experienced by third grade students of Mathematics Education Study Program during Project Based Learning (PjBL) implementation on Evaluation of Mathematics’ Learning Process and Result. 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.
本研究的目的是了解数学教育研究项目三年级学生在实施基于项目学习的数学学习过程和结果评估过程中所经历的学习困难。本研究采用描述性方法和定性方法，因为它从最初的过程到最终的产品都是相关的，并且使用的研究工具是访谈表的形式。本研究的样本是Swadaya Gunung Jati Cirebon大学教学与教育科学学院数学教育研究项目的68名三年级学生。该研究于2016年3月至7月期间进行。基于本研究的结果，可以得出结论，学生在实施项目学习过程中的学习困难是由内部因素造成的，即缺乏动力，这可以从学生在阅读和寻找与材料相关的各种参考资料方面的不足中看出，他们只依赖于一本在课堂上使用的参考书。这导致了对评估工具质量的学习缺乏理解，这可以从基于Bloom分类法的评估试题分类和评分指南的排列、使用有效性公式、可靠性、项目判别和难度指数来确定工具质量的困难以及完成最终产品的困难中看出。

This study aims to see the effect of visual thinking approach on improving students' mathematical connection ability. This is a quasi-experimental research with nonequivalent control group design. The sample is students on class VIII in Madrasah Tsanawiyah which is chosen by using purposive sampling technique. The research instruments used are a test of mathematical connection ability and an observation sheet. The results of the observations showed an increase in the activity of students and teachers in each meeting in the classroom that obtained learning by using visual thinking approach. The data of increased connection ability is not normally distributed, so the data analysis is done using U non-parametric test of Mann Whitney. From the data analysis, it can be concluded that there is no significant effect of learning by using visual thinking approach to students’ mathematical connection ability improvement.

The problem raised in this research is that students' ability in making mathematical connections is still relatively low. This is because some of the theories in the learning of teachers still enjoy this way of learning, meaning that the students are only recipient of information without inspiration to active. Therefore, the authors are interested to conduct research by applying an NHT cooperative model setting to improve mathematical connection ability of junior high school students. This study aims to determine whether the knowledge of mathematical connections of junior high school students using learning methodology is better than junior high school students using ordinary learning. This research was conducted in SMP Krida Utama Padalarang Class VII, with research method the research used is quasi-experimental method. The sample of this research is taken two classes namely class VII A as experiment class and class VII B as control class. The research instrument is a set of mathematical connection test questions consisting of 5 test questions, and then tested by using a statistical test of differential. Based on the results of research and data processing, the authors conclude that the ability of mathematical connections of junior high school students whose learning using open-ended approach with learning model setting NHT type cooperative learning is better than the mathematical connection ability of junior high school students whose learning using ordinary learning.
这项研究提出的问题是，学生建立数学联系的能力仍然相对较低。这是因为教师在学习中的一些理论仍然喜欢这种学习方式，这意味着学生只是信息的接受者，而没有积极的灵感。因此，作者有兴趣通过应用NHT合作模型设置来提高初中生的数学联系能力。本研究旨在确定使用学习方法论的初中生的数学联系知识是否优于使用普通学习的初中生。本研究在七级SMP Krida Utama Padalarang进行，研究方法为准实验方法。本研究的样本分为两个班，即实验班ⅦA班和对照班ⅦB班。该研究工具是一套由5道试题组成的数学连接试题，然后通过微分统计测试进行测试。基于研究和数据处理的结果，作者得出结论：采用开放式学习方式和学习模式设置的NHT型合作学习的初中生的数学连接能力优于采用普通学习方式的初中生。
