Teaching and learning discrete mathematics

Abstract

In this paper, we provide an overall perspective on the teaching and learning of discrete mathematics. Our aim is to highlight what research has been conducted in this area and to connect it to existing research ideas for future work. We begin by characterizing discrete mathematics and its role in the school curriculum, highlighting themes, topics, and mathematical practices that distinguish discrete mathematics. We then present potential benefits of focusing on discrete mathematics topics for mathematics education; in particular, we discuss the accessibility of topics in discrete mathematics, the connection to mathematical processes and affect, and the relevance of discrete mathematics in our current society. We also emphasize discrete mathematics from an international perspective, highlighting studies from the US, Italy, France, Chile, and Germany, which are across all school levels–primary, middle, and secondary school, and with some implications for post-secondary education. We particularly discuss discrete topics including number theory, combinatorics, iteration and recursion, graph theory, and discrete games and puzzles; we describe and situate these topics within literature. We also suggest the additional topics of game theory and the mathematics of fairness that we hope to see addressed in future studies.

Unveiling the Digital Equation Through Innovative Approaches for Teaching Discrete Mathematics to Future Computer Science Educators

“…Furthermore, students acquire knowledge about information theory, combinatorics, mathematical logic, and algorithmic graphical representation techniques. Python is utilized specifically for developing graphical computer games with libraries like Pygame (Sandefur et al, 2022). The training also encompasses programming for mobile devices and services, along with understanding the methods and tools for information and intellectual property protection.…”

Examining the pedagogical content knowledge of in-service mathematics teachers on the permutations and combinations in the context of student mistakes

“…Furthermore, they lacked conceptual knowledge to support teacher readiness to teach on different topics (Hill et al, 2008;Loong, 2014). A better understanding of teachers in teaching and learning can increase their knowledge of ways to educate students with various learning styles (Sandefur et al, 2022). Teacher success is primarily determined by better analysis of each student's responses in solving permutation and combination problems (Batanero et al, 1997).…”

Research on Nonroutine Problems: A Hybrid Didactical Design for Overcoming Student Learning Obstacles

“…Several previous studies [1][2][3] reveal that fractions play a crucial role in mathematics, as well as in other scientific disciplines [4,5], and everyday life [6]. However, fractions often pose challenges for students, such as students' limited concepts in understanding fractions, students' low ability to operate fractions [1][2][3], and teachers that tend not to integrate technology and nonroutine problems in learning [6], including at the junior high school level [7].…”
