Subject Matter Knowledge of Geometry Needed in Tasks of Teaching: Relationship to Prior Geometry Teaching Experience

This study proposes task of teaching as an organizer of dimensionality in teachers’ subject matter knowledge for teaching (SMK) and investigates it in the context of measuring SMK for teaching high school geometry (SMK-G). We hypothesize that teachers use different SMK-G in different aspects of their teaching work and that such differences can be scaled and associated with key elements of instruction. Analyses of 602 high school teachers’ responses to two sets of items designed to measure the SMK-G used in two particular tasks of teaching—understanding students’ work (USW) and choosing givens for a problem (CGP)—suggested the two scales of SMK-G to be distinguishable and differently related to experience in teaching high school geometry.

Factors Affecting Mathematics Achievement In Central Asian Specialized Universities

This study examines variables explaining student’s academic performances in mathematics from specialized engineering institutions. A survey consisting of 42 items was conducted from 127 students and statistical multiple regression was carried out to analyze the data set. Based on Fennema-Sherman Mathematics Attitude Scales followed by the result of stepwise linear regression, found a significant impact of high school geometry grades in mathematics performance. Au-thors suggest that mathematics instructors in higher education should pay attention to improve their student’s confidence, which in turn would decrease the anxiety level towards mathematics. The high school teachers should not advise their students to go to technical sciences in higher education unless the student’s confidence and high school math grade are sufficiently high

Mathematical Art: Lost in Translation

Traditionally, high school geometry has focused on the study of two- and three-dimensional figures, postulates, measurements (NCTM, 2018). Through connecting geometry, art, cultures, and mathematics, we can create opportunities for students to experience the joy and beauty of mathematics that can help to foster and/or extend other connected concepts.
