In this article, the authors explore how the 3C Model can be used to integrate other curriculum areas with mathematics, namely digital technologies. To illustrate the model, they provide a practical example of a teaching sequence. T he 3C Model is designed to create opportunities for applying reasoning and problem-solving skills and learning…

Like terms are usually defined for variables with numerical coefficients. While the definition is sufficient to combine polynomial terms, it does not help the students to combine radical, logarithmic, or trigonometric terms. The purpose of this paper is to propose a lesson that introduces a broader definition of like terms and trialed with a group…

This paper presents findings from a two-year qualitative study examining integration of computer science (CS) and computational thinking (CT) into elementary mathematics instruction. Integrated units were developed by elementary teachers and CS/CT coaches with support from university faculty with expertise in CS/CT and elementary mathematics.…

Purpose: The purpose of this paper is to describe the design and delivery of a lesson study unit in mathematics to pre-service primary teachers and to identify the opportunities and challenges resulting from the need to deliver the unit wholly online due to the COVID-19 pandemic. Design/methodology/approach: Cross-case analysis, using a…

This article analyses lesson study as a mode of professional learning, focused on the development of mathematical problem solving processes, using the lens of cultural-historical activity theory. In particular, we draw attention to two activity systems, the classroom system and the lesson-study system, and the importance of making artefacts…

This article describes a two-day lesson in which fifth-grade students took on the role of marine biology scientists, using their critical-thinking and problem-solving skills to explore human impact on the blue crab ecosystem. The purpose of "Crabby Interactions" was to help students understand the impact of human activities on the local…

Is it actually certain that our students are changing during our social studies classes? This paper aims to reveal structural development and evaluation in social studies education which is related to national curriculum requirements and focused on particular students in order to test the effectiveness of the lesson. In order to increase students'…

This booklet contains mathematics unit plans for Algebra 1, Geometry, Math for Technology, Mathematical Problem Solving, and Pre-Algebra developed by PACE (Promoting Academic Excellence In Mathematics, Science & Technology for Workers of the 21st Century). Each unit plan contains suggested timing, objectives, skills to be acquired, workplace…

The unit, designed for presentation to middle, junior high, and senior high school gifted students, contains a series of lessons which introduce the study of futures, teach several forecasting and problem solving techniques, provide students with the opportunity to examine and discuss problematic issues, and encourage students to take control and…

Constructivism emphasizes the learner as an active meaning maker and problem solver. This article reviews constructivism's basic principles, analyzes implications for curriculum work, and explores a constructivist unit-development process. Planners must decide degree of curricular integration, establish unit parameters, identify the problem, draft…

In this issue's "Classroom Notes" section, the following papers are discussed: (1) "Constructing a line segment whose length is equal to the measure of a given angle" (W. Jacob and T. J. Osler); (2) "Generating functions for the powers of Fibonacci sequences" (D. Terrana and H. Chen); (3) "Evaluation of mean and variance integrals without…

These model lessons from the primary grades are on the techniques of advertising drawn from a unit on, "Creating and Producing Tools and Techniques". They include behaviorial objectives, teaching and motivational strategies, evaluation techniques. The model lessons follow the problem solving inquiry approach in social studies using multimedia…

Describes a series of lessons used with a year-five class which encouraged the use of analogical reasoning in problem solving and giving attention to students' awareness of strategies and applications. Students were encouraged to discuss and question their own thinking to make connections among the problems being solved. (MKR)

An effective curriculum gives students the opportunity to perceive relationships among different topics in mathematics, use mathematics in their everyday lives, and apply mathematical thinking and problem solving to other curriculum areas. This book contains fun and creative ways to integrate mathematics across the curriculum with a diversity of…

Intended to challenge students in grades 4-9 to deal creatively and constructively with conflict, this interdisciplinary resource book contains 40 reproducible student worksheets that can be incorporated into social studies, science, and language arts curricula. Teaching techniques include modeling, mediation, problem-solving, brainstorming, role…
