The 2016 presidential election marked the beginning of a so-called "post-truth era" in which mis- and disinformation have contributed to political polarization and violence, the acceleration of global warming, and thousands of preventable deaths. In this paper, I draw on the results of a 2-week, practitioner inquiry-informed case study…

In this study, it was aimed to determine high school students' cognitive structures regarding to the immunity, infection, allergy and autoimmunity. In this study, it was tried to reveal the cognitive structures of high school students on immunity, infection, allergy and autoimmunity just before COVID-19. The study was carried out with 77 students.…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

The current paper aims to identify the mathematical connections activated by 10 Mexican high school students while solving mathematical tasks that involve the exponential and logarithmic function. We used the Expanded Mathematical Connections Model (EMCM) and the OntoSemiotic Approach of Cognition and Mathematical Instruction (OSA) as theoretical…

The present work explores students' repertoire of explicit knowledge fragments relevant to the atomic structure, seeking to answer which of those and through which routes are activated by students when constructing their explanations for some everyday situations. For this purpose, six tasks describing different situations were given to 225…

This study's focus was two-fold, first to look at forms of gestures teachers of multilingual mathematics classes use during teaching; and second to find out how teachers of multilingual mathematics classes utilize learners' home language, language of learning and teaching and gestures to foster understanding in the teaching of mathematics. This…

The United States and the United Kingdom have used standardized high-stakes testing as a measurement of students' cognitive level to determine success in the 21st century. Standardized tests have given teachers guidance to help them determine what to teach students and how to teach to the test. With such increased emphasis on high-stakes…

Visualizing the chemical structure and dynamics of particles has been challenging for many students; therefore, various visualizations and tools have been used in chemistry education. For science educators, it has been important to understand how students visualize and represent particular phenomena--i.e., their mental models-- to design more…

Following up on the effects of learning environments is essential to learning. The aim of this study was to examine students' mental models related to the concepts of expansion and contraction of materials. The population of the case study consisted of 155 students in a city center in Turkey. The data was gathered using open-ended questions that…

This study documents the mental representations of magnetism constructed by students aged 15-17 and attempts to investigate whether these display the characteristics of models with an inner cohesiveness and constancy; whether they share common features with typical historical models of the Sciences; and whether they evolve through conventional…

Purpose: The purpose of this study was to examine the score differences on the Texas Academic Knowledge and Skills (TAKS) Reading and Mathematics measures among students in Grades 10 and 11 as a function of music enrollment. Specifically, gender, ethnicity, socioeconomic status, and enrollment in choir, band, or orchestra or no music enrollment…
