The purpose of this study is to determine the relationship between internet addiction and loneliness levels of the gifted high school students studying at the Turkish Science and Education Center; the relationship analysis is carried out on the basis of different variables. As the goal is to present the current situation, descriptive survey model…

Science labs should promote reasoning that resembles the work that scientists do. However, this is often not the case. We present a lab in which students strive to find out which of two models best describes a physics experiment. The quantification of measurement uncertainties--another topic that is often neglected in high school…

The aim of this research was to explore the mathematical connections that pre-university students make when they sketch the graph of a derivative function and an antiderivative function. Also, we tried to explain the origin of the mathematical connections identified. We assume mathematical connections as a cognitive process through which a person…

Technically simple and extremely cheap setups for colorimetric and fluorimetric analyses using a smartphone camera are presented. Laboratory activities on digital colorimetric and fluorimetric analyses for students of secondary and higher educational institutions are proposed, namely, photocolorimetric determination of acetylsalicylic acid in…

Involving students in the co-design of educational curricula and practices can benefit both students and teachers. Students who participate in co-design may show better learning or increased agency or engagement. In the present study, we investigated what kind of science knowledge or practices can be learned by student co-designers while engaging…

Molecular genetics, a key concept in biology, is found to be very difficult for students at the senior high school level. A situation largely blamed on teachers' instructional approaches. Since the Relating, Experiencing, Applying, Cooperating and Transferring (REACT) strategy is reported to be an effective pedagogical approach for improving…

Teachers' beliefs about knowledge in their subject deeply impact their classroom practice. This study analyzed the epistemic beliefs about physics knowledge held by Saskatchewan high school physics teachers using a newly designed framework of epistemic beliefs about physics knowledge. Results suggest that teachers' epistemic beliefs about physics…

Teaching and understanding evolution is challenging because students must synthesize several biological processes that are traditionally taught separately. We developed a set of free online lessons and activities centered on a single evolutionary phenomenon -- why deer mice have different fur colors in different subpopulations -- to help high…

The aim of this study is to reveal the perceptions of high school teachers about the concept of "hidden curriculum" through metaphors. The phenomenological research design was applied in this study. The study was carried out with the participation of 128 high school teachers. The study group was determined using a convenience sampling…

The purpose of this study was to examine the assigned ratings, interrater reliability, and possible influences of school level and instrumentation on adjudicators' evaluations of orchestra performances at a national-level adjudicated music festival. Data consisted of the overall ratings assigned to orchestra performances (N = 55) at the 2017,…

Schools are responsible for helping students in their vocational career development in the sense that they should sustain students in developing skills required by the job market. Pre-tertiary school guidance is an indispensable aspect, since poor scholar guidance is always associated with failure at school. In the context of career paths, we…

An emergent theme from the past spring during COVID-19 remote learning was the difficulty of providing meaningful, relevant, hands-on, wet chemistry experiences at home and the potential impact of their absence upon student learning and engagement. This article shares the process and results of developing an appropriate, easy, inexpensive, safe,…

Background/purpose: Contemporary teaching focuses on the students' active role in the acquisition of knowledge and largely neglects the role of emotions. Given the importance of empathy when it comes to the emotional development of the individual, and the opportunities offered by history as a subject with regard to encouraging empathy, the main…

This paper reports on the first iteration of the Computational Thinking Summer Institute, a month-long programme in which high school teachers co-designed computationally enhanced mathematics and science curricula with researchers. The co-design process itself was a constructionist learning experience for teachers resulting in constructionist…

The study of mathematical problem posing (MPP) from the perspective of a learning trajectory is a new and thriving research field. The latest Chinese Compulsory Mathematics Curriculum Standards stipulate the developmental requirements of students' MPP ability at three different stages: Grades 1-3, Grades 4-6, and Grades 7-9. However, in this…
