This study investigated the differences between Taiwanese experienced and preservice elementary school science teachers' content knowledge (CK) about electric circuits and their ability to predict students' preconceptions about electric circuits as an indicator of their pedagogical content knowledge (PCK). An innovative web-based recruitment and…

Holding scientific conceptions and having the ability to accurately predict students' preconceptions are a prerequisite for science teachers to design appropriate constructivist-oriented learning experiences. This study explored the types and sources of students' preconceptions of electric circuits. First, 438 grade 3 (9 years old) students were…

This study aims to enrich a theme in the science course in the distance education process with augmented reality-based applications and to examine the effects of these applications on students' achievement and attitudes in science courses. A single group pretest and posttest experimental design was used in this research. The research group…

The aim of this research was to examine if a set of three science and technology workshops would promote first-grade pupils' science-related competence beliefs. The first workshop dealt with electric circuits and related handicraft tasks. The second workshop involved programming with Lego Mindstorms robots. The third workshop was related to…

For over a year, stories of economic devastation, food and housing insecurity, and the challenges of remote learning have dominated headlines as the COVID-19 pandemic ushered in dramatic changes for education, businesses, and communities. In the Columbus, Ohio region, the pandemic widened existing inequalities, as it did across the rest of the…

Nowadays, we are surrounded by artifacts that are capable of adaptive behavior, such as electric pots, boiler timers, automatic doors, and robots. The literature concerning human beings' conceptions of "traditional" artifacts is vast, however, little is known about our conceptions of behaving artifacts, nor of the influence of the…

In this paper there is a critical overview of the role of analogies as tools for meaning making in science education, their advantages and disadvantages. Two empirical studies on the use of analogies in primary classrooms are discussed and analysed. In the first study, the "string circuit" analogy was used in the teaching of electric circuits with…
