A number of useful and interesting exercises regarding nucleus and nuclear fission are performed to make these concepts more understandable to high school or even college students.

The aim of this study was to investigate second-grade elementary school students' performance related to their counting skills, place value understanding, and addition operation in natural numbers. A total of 205 second-grade elementary school students from Turkey participated in this study. The data were collected through a 'Personal Information…

Education must provide substantive knowledge, skills, attitudes, and behaviors toward environmental education. This study aims to identify seventh-grade students' conceptions regarding climate change, global warming, and the greenhouse effect. The research was conducted at four local secondary schools in the Special Region of Yogyakarta,…

In this study, we derived several formulas for the currents induced in a circular loop by a magnet connected to a spring-based simple harmonic oscillation system. In addition, we conducted an experiment for measuring the induced currents and compared the results with the theoretical prediction. It was confirmed that the prediction from the derived…

Children often learn abstract mathematics concepts with concrete manipulatives. The current study compared different ways of using specific manipulatives -- base-ten blocks -- to support children's place value knowledge. Children (N = 112, M age = 6.88 years) engaged in place value learning activities in one of four randomly assigned conditions in…

Science diagrams are an integral part of science because they are an important means of conveying and visualizing abstract science content. In recent years, researchers have demonstrated the educational benefits of encouraging students to draw their own conceptual diagrams, rather than focusing on interpreting diagrams given to them. To help…

The ability of living organisms to respond and adapt to a changing climate is an urgent concern. However, current educational efforts aimed at increasing US undergraduate student climate literacy primarily focus on the causes of, and abiotic responses to, climate change, mostly neglecting the biotic impacts. Here, we present a new framework, the…

This study aims to examine the effects of argumentation-supported problem-based learning (AS-PBL) carried out in the Chemistry-II laboratory course on the conceptual understanding of prospective science teachers about "Chemical equilibrium and Le-Chatelier's principle". The prospective teachers' answers were analyzed using content…

The aim of the presented study is to evaluate the influence of the quality of visuals in printed geography textbooks on the character of children's conceptions using the example of the geographical location concept. Visuals are a graphical representation of a certain phenomenon. A two-tier diagnostic test without and with three types of high and…

Purpose: Informed by social imaginary, Canadian exceptionalism, and social inclusion, this study explores how teacher candidates experience and interpret internationalization at home at one university in Canada. Design/Approach/Methods: Data were collected from three sources--(a) policy analyses of public documents related to internationalization…

The authors present a new classroom-tested lesson that was designed to engage students in the joy of mathematical inquiry through a card game, Frustration, while building number sense, understanding of uncertainty, statistical reasoning, and discourse skills. The purpose in developing and sharing these lessons is to highlight how games of chance…

Background: Recent advances in technology and computer simulation have expanded the use of virtual manipulatives in engineering education. However, especially in disciplines in which tactile concepts (e.g., force) are included, it has been claimed that learning could be compromised by substituting physical materials with computer simulations.…

This study determined the effect of misconceptions intervention on students' conceptual change in the concepts of density and floatation in basic science. The moderating effects of gender and school types on students' conceptual change in the selected concepts were also determined. The misconception interventions in this study are hands-on…

The aim of this study is to investigate the effectiveness of Gagne's model in teaching the concept of geometric shapes, triangle, circle and square, to a student with intellectual disability. A multiple-probe design across behaviors, a single-subject design, was used to demonstrate the effectiveness of the adopted model. The participant of this…

We conducted a multiyear project across three institutions to develop an instructional tutorial that supports student understanding of change of basis in quantum mechanics. Building from our previous work, we identified learning goals to guide activity development. The tutorial makes an analogy between spin-1/2 states and a Cartesian coordinate…
