This study aimed to describe the conceptual and procedural comprehension to solve linear program story problems in students who are an extrovert and an introvert. This was qualitative study with a case study method. The subjects were two students who are an extrovert and an introvert. Data collection included personality questionnaires, question tests, and interviews. Validity test of the data used time triangulation. Data analysis was conducted based on indicators of conceptual and procedural comprehension, which include data reduction, data presentation, and conclusion drawing. The results showed that the extroverted subject was able to meet all indicators of conceptual and procedural comprehension. This was reflected from the way the subject solved the questions properly according to the existing procedures. In contrast, the introverted student was also able to meet the procedural comprehension indicators, but did not meet the conceptual comprehension indicator. This was reflected from the mistakes that the subject made in comprehending the questions and the errors in interpreting the questions into mathematical model.

Mathematical Foundations

Statistical machine learning and signal processing are topics in applied mathematics, which are based upon many abstract mathematical concepts. Defining these concepts clearly is the most important first step in this book. The purpose of this chapter is to introduce these foundational mathematical concepts. It also justifies the statement that much of the art of statistical machine learning as applied to signal processing, lies in the choice of convenient mathematical models that happen to be useful in practice. Convenient in this context means that the algebraic consequences of the choice of mathematical modeling assumptions are in some sense manageable. The seeds of this manageability are the elementary mathematical concepts upon which the subject is built.

This research aimed to determine how to overcome student learning barriers in the material of one-variable linear equations using didactical design with scaffolding in class VIII of SMP Negeri 4 Sungai Raya. The form of research used in this study was didactical design research. The data source of this study were students of class VIII B of SMP Negeri 4 Sungai Raya and the data were the initial and final test answer sheets and the results of interviews. The results showed that didactic design with scaffolding can overcome student learning barriers. Before being given a didactical design with scaffolding students were not able to made mathematical models in the form of story problems, students were not able to equivalent and classify similar terms, the incompatibility of the problem solving steps ordered by the completion steps done by students, students cannot solve the problem comes to the simplest form, and students made mistakes in calculating the value of a count operation. After being given a didactical design with scaffolding students have been able to make mathematical models in the form of story questions, students have been able to equivalent and classify similar terms, the problem solving steps ordered with the completion steps done by students are appropriate, students can already solve the problem to the simplest form, and students are able to calculate the value of a calculated operation correctly even though there are a few operating errors in some problems. Keywords: Didactical Design, Learning Obstacles, Scaffolding
