The presented research focuses on verifying the confluent application of concept mapping (CM) and socio-scientific issues (SSI) according to the value-laden and moral dilemma orientation to construct problem-solving performance. This research sets up some perspectives for all 146 participants, including 139 students and 7 experts. All findings…

This dissertation investigates the voluntary usage of clickers to answer in class multiple-choice questions in general chemistry courses and its effect on student performance. The first study explored the demographic composition of two sequential introductory level chemistry courses over six terms. No difference in voluntary usage of the clicker…

A student's middle school science experience strongly impacts their future science, technology, engineering, and mathematics interest. The Japanese lesson study (JLS) model strengthens the student's experience through a research-based, collaborative, multistep, teaching-centered process focused on transforming local instructional practices. The…

The integration of Technological Pedagogical Content Knowledge (TPACK) into instructional design is pivotal for teachers. This intricate knowledge framework encompasses the interplay between technology, pedagogy, and subject matter, profoundly impacting the multifaceted aspects of student learning, encompassing knowledge acquisition, skill…

The purpose of this study was to understand if a STEM camp (Gear Up 4 STEM) offered during school breaks could improve science outcomes and engagement of elementary school students. This study followed two cohorts of students in Knox County Schools (grades 3, 4, and 5) over one school year and assessed their performance on the state administered…

In rural, geographically dispersed school districts, access to high-quality face-to-face professional development (PD) is challenging. Our study developed and compared the effectiveness of an online PD for middle-school science teachers working in remote, rural areas of Kansas with an evidence-based traditional face-to-face PD with the goal of…

This paper presents an analytical study on the impact of science denial on classroom learning outcomes in India, using multilevel statistical modeling to analyze data across various educational settings. Science denial, a growing phenomenon fueled by misinformation and cultural biases, poses a significant threat to the integrity of education. This…

A qualitative multiple-case study explored the perceptions of science teachers, administrators, and specialists on instructional strategies used in urban STEM schools to decrease the science achievement gap among African American students. The problem addressed in this study was the science achievement gap for African American students in urban…

This study examines the effects of six augmented-reality (AR)-supported lessons in lower-secondary natural science classes in Vietnam on students' conceptual understanding, engagement, and motivation. We used a quasi-experimental, non-equivalent control group design in two semi-rural public schools (grades 6-8; eight weeks). Intervention classes…

After the COVID-19 pandemic, there was an increasing demand for remote learning and an expansion in the substitution of traditional practical sessions with lab-based virtual tools. This study aimed to assess the effectiveness of virtual labs in practicing biochemical experiments and to examine the student's feedback regarding this tool. Virtual…

Due to the necessity to continue learning even during the pandemic, schools opened utilizing distance learning modalities. However, there is a dearth of evidence on the effectivity of this modalities in physics. In this study, we investigated the effects of three physics distance learning modes; the module-only (MO), virtual lab plus module (VLM),…

In comparison with traditional lectures, active learning methods have the potential to foster learner agency and consequently raise academic performance. However, these methods are often applied with little knowledge about their effectiveness. In this study, we introduced two concept maps in an undergraduate cell biology course, to investigate…

To explore the wider educational environment included in the dynamic model of educational effectiveness, this paper reexamines the association between student achievement and two national culture dimensions: Monumentalism-Flexibility and Collectivism-Individualism. Using Programme for International Student Assessment (PISA) 2018 data of 317,127…

The logistics and cost of running large class tutorials to improve learning for students in high enrolment courses raise questions about whether the associated effort and cost are worthwhile. The option to replace these class activities with online homework with its promise of built-in feedback is attractive. Using an activity theory lens and an…

This article presents a latent class model for multilevel data to identify latent subgroups and estimate heterogeneous treatment effects. Unlike sequential approaches that partition data first and then estimate average treatment effects (ATEs) within classes, we employ a Bayesian procedure to jointly estimate mixing probability, selection, and…
