Abstract

Symbol sense is the intuitive feeling of calling out symbols in the process of solving problems. Professional teachers are teachers who have graduated from the Teacher Education Program (PPG). This qualitative descriptive study aims to describe the symbol sense ability of junior high school professional mathematics teachers. Three subjects are mathematics teachers who have passed PPG. Data were collected through six symbol sense tasks adapted from Jupri and Suspiyati and interviews. Assignments and interviews were analyzed using the triangulation method proposed by Miles, Huberman, and Saldana. The findings reveal that professional teachers tend to have good symbol sense abilities. In the second symbol sense characteristic, two out of three teachers display a poor symbol sense performance by manipulating the equation directly rather than reading the assignment in depth-first to get a better understanding so that they can complete the task correctly and efficiently. The teacher should improve his symbol sense ability.

Abstract

Geometrical intuition is the ability to visualize, construct, and manage geometrical shapes in the mind when solving geometry problems. Geometrical intuition requires four skills: the ability to construct and manage geometrical figures in mind, perceive geometrical properties, connect pictures to concepts and theories in geometry, and determine where and how to begin when solving geometry problems. This geometric intuition ability is important for developing problem-solving. Therefore, we need a task that can be used to identify and develop students' geometric intuition abilities. This research aims to design a geometric intuition task. We employ design research methods to design geometrical intuition tasks by conducting a literature review on geometric intuition and geometry tasks, creating geometrical intuition tasks, and estimating and noting the possible student responses. This study produced three types of tasks based on the four components of geometric intuition. We provide a list of possible responses that junior high school students may provide, as well as practical suggestions for teachers. We recommend research using our developed task to evaluate students' geometrical intuition.
