The experience of fluency while learning might bias students' metacognitive judgments of learning (JOLs) and impair the efficacy of their study behaviors. In the present experiments, we examined whether perceptual fluency affects JOLs (1) when people only experience one level of fluency, (2) when item relatedness is also available as a cue, and…

We tested German nine-month-olds' reliance on pitch and metrical stress for segmentation. In a headturn-preference paradigm, infants were familiarized with trisyllabic words (weak-strong-weak (WSW) stress pattern) in sentence-contexts. The words were presented in one of three naturally occurring intonation conditions: one in which high pitch was…

An experiment with an electric transformer based on single coils shows how electromagnetic induction changes when the magnetic coupling between coils is adjusted. This transformer has two secondary outputs which are taken differentially. This is the basis for a widely used position transducer known as LVDT.

Because sound waves are such an abstract concept in physics, hands-on activities are often recommended to improve students' understanding and strengthen their knowledge. However, most schools do not have sufficiently sophisticated measuring instruments to perform sound wave experiments. Recently, researchers used smartphones as oscilloscopes,…

On July 19, 1969, Senator Edward Kennedy drove his vehicle off a low bridge on Chappaquiddick Island in Massachusetts. The vehicle sank in 2.1 m of water, coming to rest on its roof. According to Kennedy's version of events, he managed to escape from the submerged vehicle without injury, but his female companion, Mary Jo Kopechne, drowned without…

This study developed an online observable augmented reality dynamics experimental system that can be used in the current COVID-19 pandemic, where face-to-face experiments are difficult to conduct. The developed system enables the broadcast of mass point and rigid body measurements using an online depth camera, and remote observation using mobile…

This paper attempts to explore the underpinning pedagogy in Tharu culture -- songs and dances of Dangaura Tharus- performed in various feast and festivals. Along with this, my study focused on examining the connections of the Tharus' pedagogies with that of the formal and non-formal schools. I employed interpretivism as a research paradigm and…

Physics program for girls (PPG) is a two-week program held every summer since 2006, with the goal of engaging young women in inquiry-based physics experiments and to connect them with female science, technology, engineering, and mathematics professional role models. The program recruits young women to participate the summer after they have taken…

This mixed methods research explored the autonomous experiences of South African school students when participating in a science fair. A prominent global goal for school science education is for students to partake in scientific inquiry in order to acquire understanding of science concepts, the processes and skills of science, and the nature of…

In light of the current shifts in medical education from traditional lectures to more active teaching modalities, a peer-teaching program was introduced to a compulsory, second-year neuroanatomy course. A cross-sectional survey of 527 medical students in the six-year medical program of the National and Kapodistrian University of Athens was…

We developed a comprehensive training module for the undergraduates majoring in chemical education with a simple microfluidic experiment. The students were required to read a scientific reference offered by the instructor, then design and implement a microfluidic experiment for real sample analysis by making some modifications to the method…

The Coronavirus disease 2019 (COVID-19) pandemic in China has changed higher education dramatically, with a distinctive rise in online instruction. Here, we describe the major successes and challenges encountered during the full implementation of online chemistry instruction in higher education in China based on questionnaires answered by 56…

Professional vision is a key ability in the professional development of pre- and in-service teachers as it determines how professionals perceive and interpret situations. The aim of this study was to conceptualize an instrument for professional vision focusing on formative assessment in the context of scientific inquiry. This focus is highly…

In this article, an approach to integrate contemporary quantum physics into secondary school teaching is presented. The Erlanger concept on quantum optics provides an experimental-based guideway to aspects of modern quantum physics. We avoid the traditional historical approach in order to overcome the lack of modern concepts of quantum physics. In…

A quasi-experimental control group pre- and post-test study was used to determine the effect of a Multi-Step Inquiry (MSI) approach on pre-service elementary school teacher's conceptual understanding. The MSI study involved the development of a conceptual workbook, and a Physical Science Concept Inventory. The conceptual workbook has activities…
