Operations Research (OR) is a branch of applied mathematics that deals with optimization problems arising from different real contexts. The solving process of its problems is based on the construction and resolution of mathematical models, showing the possible connections between mathematics and the real world. Nevertheless, OR is not typically…

This article describes the design and implementation of a sensors-based entrepreneurial-minded learning (EML) module in a large (>150 students) first-year General Chemistry II course. Students worked in groups create a novel sensor that solves an existing scientific problem or improves upon an existing sensor. Students proposed and explained…

This paper investigates students' mathematical modeling activity in data-rich modeling tasks. It aims at gaining insight into how students develop meaning when modeling data-rich situations and the mathematical models produced. A tendency to model a particular dataset, rather than the phenomenon that the dataset is a particular instance of, has…

Dramatic inquiry is a teaching approach where students explore science through differentiated learning experiences, so that students can engage in learning in multiple ways (e.g., through gesture, song, written and spoken language). It positions students as competent problem solvers and draws upon students' strengths through collaborative learning…

This paper analyses the tasks allotted to students, featuring two thematic units in the 6th grade Geography textbook published in 2018 by the Didactic and Pedagogic Publishing House Ltd., Bucharest and used in the schools in Romania during the 2018-2019 school year. After a brief analysis of the textbook and its lesson structure, we studied the…

Hypothesis testing is one of the more difficult concepts for students to master in a basic, undergraduate statistics course. Students often are puzzled as to why statisticians simply don't calculate the probability that a hypothesis is true. This article presents an exercise that forces students to lay out on their own a procedure for testing a…

Calibration is a technique that is commonly used in science and engineering research that requires calibrating measurement tools for obtaining more accurate measurements. It is an important technique in various industries. In many situations, calibration is an application of linear regression, and is a good topic to be included when explaining and…

The language-experience approach to problem solving is discussed. A theme park unit provides illustrations of how problem solving can be developed. (MNS)

This manual presents instructional design strategies and sample student activities for creative problem solving. The ideas and suggestions are intended to support both students' mathematical attainment and their development of creative ability. The book begins with an introduction followed by discussions of unit design strategies and activity…

A project to tempt students to pose questions, state hypotheses, measure, estimate, compute, and evaluate their answers in terms of a problem they can see and manipulate is described. Selecting landmarks, collecting data, developing a blueprint, interior decoration, and fabrication are among the points discussed. (MNS)

Presented is an interview concerning development and implementation of the Unified Sciences and Mathematics for Elementary Schools (USMES) project, which has developed an interdisciplinary problem-solving curriculum for elementary students. (Author)

Benefits of Instant Logo are discussed. Activity cards are illustrated and suggestions for teaching the unit and managing the class are given. (MNS)

Suggestions are offered for using computers to solve scientific problems rather than focusing on computer science itself. Suggested are scientific language programming, assembly-language programming, and logical design and business language programming. A summary of available equipment and some suggestions for program implementation are included.…

This textbook/workbook for secondary school students is designed to stimulate inventive problem solving of future world problems. It is organized into four units and contains 23 lessons. Unit I defines the nature of the course and provides methods for stating and defining problems, brainstorming, working in groups, and judging ideas. Unit II…

Tessellations provide an opportunity to incorporate a variety of geometric topics in one unit, allowing students to review shapes and focus on relationships among them. Three activities are described, with illustrations. (MNS)
