What causes severe thunderstorms and tornadoes? Tornadoes, often accompanied by severe thunderstorms and hail, form in pretty much the same way as severe thunderstorms. In the continental United States, tornadoes usually form in spring and summer, when warm, humid air from the Gulf of Mexico moves across the continent from southeast to northwest…

A student laboratory experiment to investigate the intrinsic and extrinsic bandgaps, dopant materials, and diode design in light-emitting diodes (LEDs) is presented. The LED intrinsic bandgap is determined by passing a small constant current through the diode and recording the junction voltage variation with temperature. A second visible…

Purpose: This study examines how different purposes can support teachers in their work with progressions as a part of a teaching sequences in science in primary school. Design/Method: The study was carried out in two classes working with inquiry and the events that took place in the classroom were filmed. In the study, we have chosen to use the…

In this article, Robin James describes the Sand Yacht Challenge. The race took place on sand between small, wind-powered land yachts made by groups of children from four local schools. The project provided a term of collaborative opportunities at the designing and testing stage, followed by a competition when the students raced them. It was…

International large-scale assessments such as the Programme for International Student Assessment (PISA) have emerged as important tools for understanding educational systems within Asia and around the world. Although the achievement scales tend to capture the majority of the world's attention the background scales have become important tools in…

The challenges of contemporary society require pupils to make informed decisions and take responsible actions on problems related to science and technology. This work provides guidelines to support teachers in the design of learning scenarios that enable achievement of these goals. Two classroom examples based on contemporary news events explain…

In this study, it was aimed to investigate the effects of microscope simulation software on prospective science teachers' laboratory achievements, microscope use, laboratory reports and views on microscope which was prepared for general biology laboratory. The case study design was adopted for the research. The participants were 49 science teacher…

The study of vibration in uniform beams provides physics teachers with a platform by which a broad range of physics vibration-related topics can be explored without expensive and specialized equipment. This paper presents two laboratory exercises related to lateral beam vibrations. These exercises use beam theory coupled with free sound-analysis…

In recent years, educational researchers have investigated teacher-student interactions in science classrooms, paying particular attention to interaction patterns and the purpose of such interactions. Although different patterns and purposes have been uncovered through these investigations, there is little research on how college instructors use…

This study was designed to delve into the impact of differentiated science education for gifted students on prospective classroom teachers in terms of some variables. A concurrent embedded research design from mixed research methodologies was employed in this study. The participants were 69 sophomore students studying in the Department of Primary…

This study describes how culturally relevant pedagogy in a project-based science class improved student engagement and comprehension. We focus on bicultural students exploring cultural objects and household inventions with family members and connecting scientific concepts to their families' funds of knowledge. We use a multiple-case study design…

The aim of research was to reveal the views of preschool teachers on using out-of-school learning environments in preschool education. It was a qualitative research conducted by phenomenological method and eleven preschool teachers from Turkey were included in it. The research data was obtained by interview and the interview form prepared by the…

Citizen science projects are an increasingly popular way to engage the public in the process of science. However, few studies have evaluated learning outcomes beyond knowledge gains in formal learning settings with youth. This study evaluated the effects of a classroom-based citizen science project in which middle and high school students…

The theory of evolution can be a useful basis for developing students' understanding of ecology. Our study used concept maps to examine the development of sixth-grade students' understanding of the Antarctic ecosystem following several evolution 'Science Days' conducted at 'Nature Campus' -- an informal learning environment comprised of a natural…

Previous study on the nature of science indicated that the use of activities is essential and important in the teaching of the nature of science subjects. The aim of the research is to develop alternative activities for helping students in the seventh grade of middle school develop their views on the nature of science and for better teaching the…
