The purpose of this study was to investigate gender differences in Omani 10th-grade students' perception of their science teachers' Pedagogical Content Knowledge (PCK) in both realities and as they desired. Two versions of electronic questionnaires consisting of sixteen main items were designed to achieve the aims of this study. These two versions…

As elementary schools across the U.S. continue to adopt new science education reform, attention is needed to understand how teachers make sense of using engineering design to teach science in their classroom settings. This study examined fourth-grade teachers' sense-making with learning to integrate engineering design-based science instruction and…

Informal learning organizations such as museums, zoos, aquaria, gardens, and community-based organizations are often positioned as having programming that fill a void that may exist in the lives of youth participants. Often these institutions do not recognize the assets that youth gain from their own homes and communities and bring to bear in…

The main aim of this research is to examine the effect of an instructional design based on the Algo-Heuristic Theory of Instruction (AHTI) on students' mathematics performance and logical thinking skills in the subject of 7th grade mathematics. The research is grounded in a mixed method. In the quantitative part of the research, a…

Access and performance in advanced high school physics have been persistently inequitable when considering student ethnicity and gender. This quasiexperimental, observational study examined access and performance of students in four Advanced Placement (AP) Physics courses in 2018-2019: AP Physics 1 (N = 150 451), AP Physics 2 (N = 20 466), AP…

The rapid shift from face-to-face to remote instruction in 2020 has resulted in recalibration of lecture and laboratory pedagogy. This research analyzed the impact of remote learning on student motivation and sense of belonging in large enrollment chemistry courses. Student responses were parsed according to specific demographics including gender,…

There has been increasing interest in exploring heterogeneous treatment effects using machine learning (ML) methods such as causal forests, Bayesian additive regression trees, and targeted maximum likelihood estimation. However, there is little work on applying these methods to estimate treatment effects in latent classes defined by…

The aim of this study was to conduct a systematic literature review on the use of serious games in science education between 2016 and 2020 years. A total of 39 articles were included from Science Citation Index-Expanded (SCI-Expanded), Social Science Citation Index (SSCI), Arts & Humanities Citation Index (A&HCI) and Emerging Sources…

The aim of this study was to determine the effectiveness of the Science teaching process to middle school students using teaching materials prepared via augmented reality (AR) technology. In the experimental study, 61 sixth grade students at a middle school in Antalya in the 2019-2020 academic year were selected randomly, and the mixed research…

Contribution: A 3-D interactive learning environment, from which students of different levels in the control engineering background can benefit regarding classroom demonstration and online experimentation, is present. The findings support that students can benefit from the application of the online laboratory. Background: Control system design is…

Active inquiry plays a key role in science education. To facilitate children's motivation, alternate reality games are applied to engage children actively in inquiry in authentic learning contexts. However, the complexity of real-world contexts and the ambiguity of game puzzles increase the difficulty for children to conduct effective inquiries.…

Growing evidence suggests that students' self-beliefs about altering their academic abilities can directly influence long-term achievement. These self-beliefs or mindsets can either be fixed (unchangeable) or growth oriented. Students with growth mindsets believe their academic abilities can change, which leads to higher grades and academic…

The purpose of the present study was to examine whether parents' utility value perceptions predicted their children's utility value perceptions, demonstrating social contagion effects. We also examined whether utility value would predict achievement. This is a cross-sectional study that utilized data from a subsample of adolescent students from…

The COVID-19 pandemic necessitated the move to online teaching and assessment. This has created challenges in teaching laboratory skills and producing assessments that are robust and fair. Our solution was to use bespoke laboratory videos to provide laboratory training and to generate unique data sets for each student in coursework and exams. For…

Purpose: This research aimed to examine the usefulness of a microbiology digital handout as a teaching material validated by experimental research in the improvement of science process skills and cognitive learning outcome of students. Methodology: The study comprises two methods: experimental research and development research. The experimental…
