Distance education programs have become the preferred option for most higher education institutions to continue teaching during the COVID-19 pandemic, but the effectiveness of some online courses, especially those engineering courses with experimentation activities, remains disputed. The main challenge is fostering collaborative problem solving…

The purpose of this article is to demonstrate how exponential functions and patterns can be taught by well-structured lessons composed of classroom activities, mathematical questions, discussions, and solving problems. Sawyer (1943) used a rope-and-post system to introduce the concept of logarithms and to calculate a product by adding the…

Many educational tools that are recommended for the training of normal students are often encountered in programs that do not work very well and are subsequently abandoned. One of the important points that program developers should now consider is that teaching tools are presented in accordance with individual differences. It is seen that the…

Many studies have shown benefits associated with engaging students in problem-solving activities prior to administering lessons. These problem-solving activities are assumed to activate relevant knowledge and allow students to develop some initial knowledge structures, which support understanding of the lesson. In this paper we report the results…

This study aims to develop an electronic library-based learning environment to support teachers in developing web-based problem-solving activities and analyzing the online problem-solving behaviors of students. Two experiments were performed in this study. In study 1, an experiment on 103 elementary and high school teachers (the learning activity…

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…

A method of instruction is presented in which learners construct their own understanding by engaging in experiments directed to solving specified problems. The method is based on how successful inventors learn and create new inventions.

Activity sheets posing problems in which students must examine and test various possibilities are presented. (SD)

Gives several sample experiment problems for electricity and magnetism. To solve an experiment problem, students have to do one or more of the following: clarify a poorly defined problem, divide a problem into parts, access the appropriate concept needed to solve each problem part, decide whether approximations are appropriate, design an…

Describes an experiment to determine which of four objects, hollow cylinders, solid cylinders, hollow balls, and solid balls, will reach the bottom of an inclined plane first when released simultaneously. Provides solutions to the problem and supplementary exercises. (MDH)

Presented are ways to teach pupils the concept of "sphere" with a methodology far removed from memorization of a formal definition of the concept. The material illustrates an approach to teaching that focuses on open exploration of ideas with children. Many experiments and starting points for exploration are suggested. This document has…

Describes the process of problem identification, data collection, and generalization in a mathematical experiment to find the speed at which a bug travels at the end of a fan blade. Presents the learning outcomes of the experiment and possible implications of using this teaching method. (MDH)

Twenty-one competency based instructional units are included in this solid-state electrical controls curriculum which is designed to upgrade the skills of coal mine electricians who work with mining equipment that has solid-state electrical controls. Each unit contains one or more student competency sheets with necessary attachments or handouts,…

The rapid growth of science and technology has a tremendous impact upon how an individual functions in today's society. This experiment-oriented course encourages the student to investigate home economics subject matter from a scientific viewpoint. Using the scientific method to solve problems and make decisions, the student conducts laboratory…

This paper examines ways in which coherent reasoning about key concepts such as variability, sampling, data, and distribution can be developed as part of statistics education. Instructional activities that could support such reasoning were developed through design research conducted with students in grades 7 and 8. Results are reported from a…
