Reading mathematical texts is closely related to the effort of the reader to understand its content; therefore, it is reasonable to consider such reading as a problem-solving activity. In this paper, the Principle of Mathematical Induction was given to secondary education students, and their effort to comprehend the text was examined in order to…

The present study aimed to remediate pre-service teachers' misconceptions about sampling distributions and to develop their conceptual understanding through the use of conceptual change texts (CCTs). The participants consisted of 84 pre-service teachers. To determine the pre-service teachers' conceptual understanding of sampling distributions, an…

Advancements in mobile technologies have accelerated mobile Augmented Reality (AR), and many applications have been developed and presented in online stores. This study aims to evaluate the accuracy of the AR model of the Solar System simulated in mobile AR applications located in the Google Play Store. The applications were examined in the store…

An ordinary soap bubble immersed in a pure carbon-dioxide atmosphere, created e.g. by sublimating chunks of dry ice (solid CO[subscript 2]), will expand within a few minutes to a volume exceeding the original one with a factor of almost ten. Considering that the bubble simultaneously experiences a cooling of ~30 ?C one would perhaps expect a tiny…

In this work, we report the development of a low-cost Arduino-controlled device for didactic activities in light polarization. The main body of the prototype was designed and produced using laser-cut medium density fibreboard parts, including gears and pulleys. As a light source and detector, a 532 nm laser pointer and a light dependent resistor…

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…
