Abstract

The research aim to determine whether the ability of understanding mathematical concepts students on the application of the Learning Cycle is higher than the ability of students understanding of mathematical concepts in conventional learning in IPS XI MAN Gunung Padang Panjang. The research was quasi-experiment, and the research design Randomized Only Control Group Design. Research procedures are: preparation, execution and completion. The instrument used was a test essays. The hypothesis was tested with Mann-U Whitney test. Based on the research results, obtained an average ability students understanding of math concepts in the experimental class was 87.12, while the control class is 59.66 Hypothesis tests using the Mann- U Whitney obtained 3.96. That is, the test statistic Z = 3.96 is greater than the critical value = 1,645, so the research hypothesis is accepted. Thus, the ability of students understanding of mathematical concepts in the application of the Learning Cycle is higher than the ability understanding mathematical concepts students in conventional learning.Key words: Learning Cycle, understanding of math concepts

Abstract

In general, the conic section equation consists of three parts, namely quadratic, cross-product, and linear terms. A conic sections will be easily determined by its shape if it does not contain cross-product term, otherwise it is difficult to determine. Analytically a cone slice is a quadratic form of equation. A concept in linear algebraic discussion can be applied to facilitate the discovery of a shape of a conic section. The process of diagonalization can transform a quadratic form into another form which does not contain crosslinking tribes, ie by diagonalizing the quadrate portion. Hence this paper presents the application of an algebraic concept to find a form of conic sections.
