This study explored the effect of conventional laboratory practical manuals on pre-service teachers' integrated science process skills (ISPS). A validated multiple-choice questionnaire with the ISPS components was used to collect data. No significant difference between pre-service subject-specific teachers' (biology, physics and chemistry) ISPS…

Psychology has been an avocation of mine for almost 20 years, and over the past decade I have begun integrating this knowledge into my classroom. My first introduction to psychology was through the Myers-Briggs Type Indicator®. MBTI looks at preferences in how people interact with the world around them. By recognizing how different students…

For many students, the first--and sometimes only--chance to look through a microscope is in high school biology class, where they observe plant and animal cells up close. Even in college, few students use a microscope for a subject other than biology. Thus, it can be a surprise to learn that microscopes are a primary tool used to understand the…

In hydrostatics, pressure measurement with U-gauges and their relationship to density is a well-known experiment. Very little is studied or experimented with the dynamics of the movement of a liquid in a U-tube probably due to its theoretical complexity but, after all, it is a simple damped oscillating system. In this paper we present a relatively…

One of the fundamental problems for the college students is not being able to solve the multi-concept physics problems. The reason is that the problem solving strategies is limited to known-asked strategy (traditional strategy).Though this strategy can only be used to solve the problems of mono-concept physics. Therefore, this research on the use…

This study aimed to compare the objectives of environmental education topics in various countries. The present study is a qualitative study and content analysis was used to analyze the data. The results revealed that the categories of the objectives regarding the environment topic in the primary education were found to be higher in Turkey compared…

Children are captivated with how things work and they like to build things and in many ways, engineering comes naturally for them. Progress does not come from technology alone but from the melding of technology and creative thinking through art and design. There has been a push for STEAM-based curricula to be included in science classrooms and the…

Propagation of sound waves is one of the fundamental concepts in physics. Some of the properties of sound propagation such as attenuation of sound intensity with increasing distance are familiar to everybody from the experiences of daily life. However, the frequency dependence of sound propagation and the effect of acoustics in confined…

We use analogies to provide introductory laboratory students intuition into measurement uncertainties. Using a battery-resistor circuit we discuss uncertainty concepts and derive expressions for uncertainty of the mean and sums of uncertainties. Finally, we draw attention to the fact that the interpretation of standard deviation as uncertainty…

How do secondary school science teachers justify the model of a particulate nature of matter, and how do the arguments they use relate to historical arguments? To find out, we individually interviewed 11 in-service secondary school science teachers (certified to teach chemistry and/or physics in secondary school, and with 2 to 30 years of teaching…

According to variation theory, it is essential to enable students to focus on the object of learning and discern its critical features, but the features that "it is possible" to discern often depend on the equipment used. Thus, in labs, the experimental technologies used may shape students' experience of focal phenomena, in a…

This study investigated students' modeling progress and strategies in a problem-solving simulation game through content analysis, and through supervised and unsupervised lag sequential analysis (LSA). Multiple data sources, including self-report models and activity logs, were collected from 25 senior high school students. The results of the…

This article is the second of a two-part series that explores science teachers' and their pupils' experiences of using different pedagogical approaches based on understandings of how brains learn. Part 1 (Torrance Jenkins, 2017) focused on the two approaches rooted in cognitive psychology: Cognitive Load Theory (CLT) and Cognitive Acceleration…

Studies show that teachers and students use humour when communicating with each other in a science education context. This study investigates the use of humour during a collaborative inquiry laboratory task on an undergraduate chemistry course and an undergraduate physics course. Seven groups of students working on a collaborative inquiry task…

The goal of this project is to analyze the views of pre-service physics teachers on STEM education and STEM activities. For this purpose, qualitative approach and semi structured interview forms were used as data collection tools. The interview forms were analyzed using content analysis technique. The participants of the study are eight students…
