The main purpose of this study was to examine the effects of Problem-Solving Strategy Steps (PSSS) on students' achievement, skill, and confidence. The study was conducted in a two-year college classroom with 70 students from two different groups enrolled in a physics course. One of them was randomly selected as an experimental group (EG) and the…

Group discussions were introduced in an introductory physics course at the National University of Laos. About 200 students discussed two qualitative questions in groups of 3-4 students. This was followed by whole class discussions. We examined this new method and identified problems and possibilities with it. Seven groups were recorded and…

Physics teachers use experimental devices to show students how scientific concepts, principles, and laws are applied to understand the real world. This paper studies question generation of secondary and under-graduate university students when they are confronted with experimental devices in different but usual teaching situations: reading about…

A calculus-based introductory physics course, which is based on the Matter and Interactions curriculum of Chabay and Sherwood (2002), has been taught at Purdue University. Characteristic of this course is its emphasis on modeling. Therefore, I would like to investigate the effects of modeling-based instruction and interactive engagement on…

Laboratory work is one of the main forms of teaching used in chemistry, physics, biology and medicine. For many years researchers and teachers have argued in favor of or against this form of education. Student opinion could be a valuable tool for teachers to demonstrate the validity of such expensive and work intensive forms of education as…

The Mechanical Waves Conceptual Survey (MWCS), presented in 2009, is the most important test to date that has been designed to evaluate university students' understanding of four main topics: propagation, superposition, reflection, and standing waves. In a literature review, we detected a significant need for a study that uses this test as an…

The paper deals with innovative teaching methods at universities. The result of this effort is the interactive P&E method, whose main idea is the interactive work with students while solving problem tasks. The main aim of the given method is to change the students' position, by means of experiment analyses and qualitative tasks, from a passive…

The conversation between myself and Professor Lederman took place in Malmö, Sweden on August 25, 2007. The purpose of the conversation was to elaborate on the past, present and future of nature of science research and also to provide insights for beginning researchers. In this text I am providing the questions about which we talked and my…
