High school students' difficulties with quantum physics (QP) are partly due to their limited understanding of the nature of science (NOS). The essence of QP can only be understood with informed views about NOS aspects such as the role of models and the relevance of controversies between physicists. Inversely, QP is an ideal topic for teaching…

A good number of instructional strategies are identified to help students overcome their learning difficulties in the mole concept. However, Ghanaian senior high school students continue to have difficulties in the mole concept. Hence, there was the need to examine the perceived nature of learning the mole concept in the perspectives of male and…

Although the "Next Generation Science Standards" (NGSS) have three dimensions, the crosscutting concepts are often the forgotten dimension. One reason teachers may not emphasize the crosscutting concepts might be because they are broad, domain-general constructs that can be difficult to conceptualize in a meaningful way. Yet, when taught…

Educational initiatives in multiple disciplinary areas call for student engagement in the practice of argumentation (CCSSI, 2010a, 2010b; Mullis & Martin, 2017; NGSS Lead States, 2013; OECD, 2018). In science education, immersive argument-based inquiry (ABI) is one category of approaches which integrates argumentation in all classroom activity…

This paper addresses the ways that real objects are important for conceptual development and understanding of pi. While using real objects in teaching and learning pi with nine university pre-service teachers (PSTs) of Mathematics, the teaching and learning processes were framed under the lens of social constructivist perspective (Vygotsky, 1978).…

The purpose of this study was to explore how emotions and identity development create pathways for White deans of students to understand their responsibility in fostering a campus community that is equitable for all. From the frameworks of emotional intelligence and White identity development, I illustrated the nature of the varying, often…

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…
