Abstract

This study aims to describe students geometry problem solving abilities based on APOS theory in terms of field dependent and field independent cognitive styles. This type of research is descriptive research with a qualitative approach. The research subjects were 4 students of class IX SMPN 1 Jember which were grouped based on cognitive style, namely 2 students with field independent cognitive style and 2 students with field dependent cognitive style. Methods of data collection using problem solving tests and interviews. The results of data analysis show that FD students tend to be able to write and mention information in questions, but still have difficulty in explaining the meaning of the questions. FI students tend to be able to write and explain information on questions. At the process stage, FI and FD students were able to model and explain the stages well, but FD still had errors in changing the shape of the mathematical model correctly. At the object stage, FI students work on questions freely, while FD students work on questions in detail or fixate on structured steps, FD students also have difficulty explaining their work. At the schema stage, FI and FD students can explain how to use the information in the problem, but FD students still experience errors from the process stage to drawing conclusions as a solution. Field independent students tend to be free or not fixated on complete and detailed steps, while field dependent students tend to be bound or fixated on complete and detailed steps.

Abstract

A visual presentation is a form of representation that helps students express the equations of logarithm functions. This is a qualitative descriptive study to identify the success of high school students in representing graphs of logarithm functions. Four students of SMA Hang Tuah 4 Surabaya became the research subjects. Data were collected through the researcher as the main instrument, TMGFL questions, and interview guidelines. The data were analyzed by researchers using the view points of the stages of translation of representation from verbal form to graphs. The subject's success in representing the graph of a logarithm function is based on the accuracy of reading the information, translating the equation into a simple form, determining the coordinates of the points traversed by the graph, connecting the points to form a graph, and verifying it. This study has a weakness, students who succeed in describing graphs of logarithm functions, for that further research is needed to identify the failures of students who do not succeed in representing logarithm functions and find solutions.

Abstract

Heat transfer is a physical phenomenon that can be represented in the form of a mathematical model. In this study, heat transfer occurs in a viscoelastic fluid through an elliptic cylinder surface with free convection flow. The mathematical model of heat transfer is obtained from partial differential equations and solved numerically using the Forward Time Center Space (FTCS) scheme. Numerical solution is carried out based on an algorithm compiled by an iterative process according to a predetermined point. The iteration process is carried out until it produces a stable and convergent value. Furthermore, the algorithm is implemented into the Matlab programming language with the influence of a heat variable, namely the Prandtl number (Pr). Several test results that have been carried out during the iteration process have shown that the FTCS scheme is stable along the space and time grid. In addition, this scheme shows that the obtained difference equations are proven to produce consistent and convergent graphs. Based on the resulting graph, the greater the value of the Prandtl number, the smaller the resulting temperature. This is in accordance with the definition of the Prandtl number, which is the heat determining parameter which is the ratio between the kinematic viscosity value and the heat diffusivity, so that the large Prandtl number can inhibit heat transfer that occurs on the surface of the object.
