Summary
The article emphasizes the importance of successful mathematical communication, that is, using proper mathematical notations and transforming statements into formulas, symbols, or drawings. Mathematical communication, solving real-life problems, connecting mathematical ideas, and reasoning are higher order thinking skills (HOTS) that are developed during mathematical education. The authors present a mathematics learning strategy for module design that helps math majors to improve HOTS and self-efficacy. The strategy is based on the four main stages, that is, defining, designing, developing, and disseminating. Throughout the stages a large variety of activities is performed such as analysis of curriculum and relevant material, designing module prototype, testing, collecting and evaluating feedback from the experts and students. This strategy helps to achieve the desired goals of developing the skills for mathematical communication.

Relevance for Complex Systems Knowledge
The authors state that students should develop higher order thinking skills to learn mathematics successfully. They also note that mathematics is base for solving many complex problems in engineering and economy, and effective mathematical communication leads to successful problem solving. In addition, mathematical communication is a part of mathematical skills which consist of successful application of mathematics to solve real-life problems, ability to connect mathematical ideas and ability to reason the conclusions. These skills are key of success to solving any complex problem as critical, logical, and systematic thinking is developed in the background.

Point of Strength
The strength of the article is approach to develop mathematical communication skills which is base for solving many complex problems in various fields of engineering and economy.
