Investigating Pre-Service Secondary Mathematics Teachers’ Reasoning When Learning Trigonometry Using The Line Segment Approach, Lawrence Ssebaggala

Theses and Dissertations

Review of the history of trigonometry content and pedagogy indicates the necessity and importance of trigonometry in the school curriculum (e.g., van Brummelen, 2009; van Sickel, 2011). For example, understanding trigonometric functions is a requirement for understanding some other areas of science, such as Newtonian physics, architecture, surveying, and several branches of engineering. Research indicates that teachers have a narrow and inadequate understanding of trigonometry, researchers (e.g., Hertel, 2013; van Sickel, 2011; Weber, 2005) posited that learning trigonometry in a way that fosters and advances quantitative reasoning can help alleviate difficulties faced in the teaching of trigonometry. Examining participants’ reasoning …
