Description Profile of Understanding Layer Concept of Conic Section of Mathematics Education Students 2016 of FKIP UKSW

摘要

This qualitative descriptive study aimed to describe the profile of understanding layer of the Conic Section concept toward Mathematics Education Students 2016 of FKIP UKSW. The understanding layer includes eight layers, Primitive Knowing (Pk), Image Making (Im), Image Having (Ih), Property Noticing (Pn), Formalising (F), Observing (O), Structuring (S), and Inventising (Iv). Subjects were taken by purposive sampling technique and obtained 5 Mathematics Education Students 2016 of FKIP UKSW. Data collection techniques include observation, testing, and Interview. Data analysis techniques are data reduction, data presentation, and conclusion. Based on the findings, there are some points exposed:1) to solve problem about determining a point on the circle, all subjects using Iv layers; 2) to solve the problem of parabolic equation, 60% of the subjects using Iv layer, and respectively 20% of the subjects using Im and Ih layers; 3) to solve problem of parabol focal point, 60% of the subjects using Im layer, and respectively 20% of the subjects using Iv and Ih layers; 4) to solve problems in the area of Ellipse, 60% of the subjects using Im layer, and respectively 20% of the subjects using Iv and Pn layers; 5) to solve problem of the distance to the center point of the peak, 40% of the subjects using Iv layer, and respectively 20% of the subjects using O, Pk, and F layers; 6) to solve problem of the hyperbolic equation, 20% of the subjects using Pn layer, and respectively 40% of the subjects using Iv and Ih layers; and 7) to solve problem on the hyperbolic asymptote, 60% of the subjects using Im layer, and respectively 20% of the subjects using Iv and Ih layers.
