Abstract

This research describes the knowledge and beliefs of pre-service teachers about mathematics. Data collection of this research using written test of 143 mathematics pre-service teachers who have taken six semesters at Universitas PGRI Semarang, and interviewing of three pre-service teachers who are not consistent between knowledge and belief. The data are presented in the form of descriptive quantitative and analyzed qualitatively, including data reduction, data display, and conclusions drawing/verification. The results show that most of the knowledge of pre-service teachers are consistent with their beliefs. It is indicated that pre-service teachers’ knowledge has been internalized into a strong belief that affect their words and behaviors. The belief of almost half of pre-service teachers who become respondents changes because of lecturer activity effect. It can say that belief changes at any time, both the process of alteration and the formation of new beliefs as well as the reinforcement of the beliefs they have.

Abstract

This research aims to explore students’ difficulties in resolving Nonhomogeneous 2nd Order Ordinary Differential Equations with initial value problems. The method that can be used to solve this equation is the undetermined coefficient and the Laplace transformation. This research is used descriptive method. The subjects of this study were 73 students in the second year of the Mathematics Education. Data is collected through tests and interviews. Data were analyzed descriptive qualitative. The results of data analysis show that in undetermined coefficient method, students difficult in determining the particular solution of non-homogeneous second-order ordinary differential equations. This is due to student errors in the first step especially in determining the characteristics equation. Whereas, for the Laplace transformation method, students most difficulties are in the step of solving the subsidiary equation. This is due to the weakness of students in completing arithmetic operations in the form of fractions and partial fractions.
