Abstract:
This study aims to determine the role of Guided Inquiry in understanding students' concepts in learning the Pythagorean theorem, through student worksheet-based guided inquiry learning models. This study uses descriptive qualitative research methods, which were carried out in class VIII D at SMP Muhammadiyah 1 Gamping. Data collection techniques used were documentation, observation, and written tests. Data obtained in this study were analyzed using data triangulation techniques. The results showed that the Guided Inquiry had a role in helping students to understand the concept of the Pythagorean theorem formula, through several stages of learning. In learning that uses guided inquiry, students can understand the Pythagorean theorem formula by finding it on their own and being facilitated by the teacher. Also, student learning outcomes indicate that the average value obtained by students is above the Minimum Mastery Criteria score for mathematics subjects of 65.

Abstract:
The purpose of this research is to consider the benefit of applying GeoGebra interactive media to improve student achievement in learning derivatives. This study was experimental research using counterbalance design. The population of the study was four classes of grade XI students of SMA Negeri 3 Jayapura academic year 2018/2019 consisting of 122 students. Purposive sampling was applied in this study to get two experimental classes with the number of students were 22 and 26 respectively. In both experimental groups received the same treatment which were learning using GeoGebra interactive media and learning without using GeoGebra interactive media which applied orderly. This process was implemented four times at both classes interchangeably. The data of the study was collected from participant’s pretest and posttest at every learning treatment. Data was analyzed using Wilcoxon Signed test with the significance level (two-tailed) of 0.05. The result of the study shows that there are significant differences in learning outcomes of the two types of learning. The learning process which was designed using GeoGebra interactive media obtained the superior learning outcomes.

Abstract:
This Qualitative study aimed to describe the students the mistakes in solving the problems related to cubes and cuboid topics based on Newmann's procedures. To gather the data, three students of primary school teacher department in a university in Kupang, Indonesia, with a high, moderate and low problem – solving skills were chosen to be analyzed further using descriptive method. The result showed that the students with a high problem – solving skill were doing wrong in writing the final answer due to an incomplete understanding of cube and cuboid. The students with a moderate problem – solving skill were doing mistake in transforming the word problems into mathematical expression since the students were not accustomed to do non – routine problem. Furthermore, the students with the low problem – solving skills were doing mistakes in transforming word problems into a mathematical expression, during the process and writing the final answer. The mistake was emerged due to students’ inability to understand the problems and incomplete understanding of the concept of cube and cuboid.

Abstract:
This study aims to describe students' mistakes in solving rectangular problems based on their cognitive development. This research is a descriptive qualitative study with 4 research’s subjects taken based on purposive sampling. Data collection techniques use tests, namely Test of Logical Operations and Problem-solving Tests. Data analysis techniques include reduction, presentation, and data verification. The results of the study show that mistakes that are often made by students are less complete in writing what is known and asked about the problem. At the stage of devising a plan, students are wrong in determining the formula, the complete steps to be used, and do not write an answer. At the stage of carrying out the plan, students tend to immediately calculate what is known in the problem, not even writing answers at all. Students do not check the answer so that the results of their conclusions and conclusions are wrong.

Abstract:
Development of Zone of Proximal Development (ZPD) a learner needs guidance, help from adults or peers with a higher skill set in order of achieve a higher level of development. The level of knowledge or gradual knowledge is called by Vygotsky as scaffolding. Scaffolding means giving learners helps during the early stages of learning, then reducing the quantity of help and giving the learner opportunity to immediately take on the greater responsibility, after being able to do tasks on their own. One in the statistics Lesson program is Statistical Method, which requires high-level thinking since the students are hoped to be able to analyze statistics inference. In this case, students need help during the learning process in order to understand the concept of Statistical Method material optimally. The help could be in the form of guidance, encouragement, outlining problems into other forms that enable students to be independent. By implementing the ZPD process in the form of scaffolding stage, students are able to understand concepts of Statistical Method material optimally.
