This research is motivated by a linear equations system, which is the basis for studying necessary linear algebra materials, such as rank, range, linear independent/dependent, linear transformations, characteristic values and vectors. There are still prospective mathematics teachers who have difficulty solving linear equations system and…

An evaluation of the national curriculum by practitioners suggests that learning materials across school levels still overlap, are irrelevant to student development phases and competencies required, too challenging for students to learn, too broad in terms of topics, and lacking in depth. This evaluation encourages the needs for special studies…

The emerging of formal mathematical proof is an essential component in advanced undergraduate mathematics courses. Several colleges have transformed mathematics courses by facilitating undergraduate students to understand formal mathematical language and axiomatic structure. Nevertheless, college students face difficulties when they transition to…
