The purpose of this study was to uncover pre-service science teachers' images and misconceptions regarding atomic orbital and self-ionization concepts. This study involved a total of 68 pre-service science teachers working at a public university during the 2015-2016 academic year. In this qualitative study, data were collated with the use of…

The study examined the impact of students' absolute age-position at the time of testing by grade level and gender on their achieved level of mathematics, reading and science performance. An analysis was conducted based on a sample of 11,500 15-year-old pupils in the United Arab Emirates who participated in the OECD's Programme for International…

The development of new medicines holds particular fascination for chemistry, biochemistry, and biology students interested in a career in medicine or the life sciences. The identification and refinement of lead compounds to treat diseases requires researchers to be facile in a number of different disciplines including organic synthesis,…

One of the most challenging things a professor of science in a college setting deals with is the apprehension of students toward the very idea of science and scientists. This feeling of science anxiety does not appear to be limited by nation or culture and is often spread across all ages of students. The concept of "science is hard" is…

Since 2013, 39 states and the District of Columbia have adopted the Next Generation Science Standards (NGSS) or similar standards based on the National Research Council's "A Framework for K-12 Science Education," signaling a commitment to high-quality and rigorous science education for all students. States' previous science standards…

From a sociocognitive perspective, item parameters in a test represent regularities in examinees' item responses. These regularities are originated from shared experiences among individuals in interacting with their environment. Theories explaining the relationship between culture and cognition also acknowledge these shared experiences as the…

Research has been conducted to develop a physics learning media in the form of an Android-based pocket book. We designed a Harmonic Oscillation Pocket Book and tested its feasibility and effectiveness in improving the cognitive learning outcomes of students. This study used the research and development method adapted from the ADDIE model. The…

Large-scale assessments (LSAs) use Mislevy's "plausible value" (PV) approach to relate student proficiency to noncognitive variables administered in a background questionnaire. This method requires background variables to be completely observed, a requirement that is seldom fulfilled. In this article, we evaluate and compare the…

This study examines the implementation of flipped classroom with peer instruction teaching strategy to Grade 7 public high school students in Laguna, Philippines. To analyze the effect of flipped classroom with peer instruction on Chemistry achievement, a two-group quasi-experimental pretest-posttest research design was used. In addition, student…

A concept for undergraduate mechanics courses at universities is introduced where traditional pencil-paper based exercises are partially replaced by experimental exercises, in which smartphones are used as measurement devices. A detailed guidance for practical realization and implementation of these tasks formats into the course is presented.…

For efficient and effective pedagogical interventions to address Uganda's alarmingly poor performance in Physics, it is vital to understand students' motivation patterns for Physics learning. Latent profile analysis (LPA)--a person-centred approach--can be used to investigate these motivation patterns. Using a three-step approach to LPA, we sought…

International large-scale assessments (ILSAs) have become an important part of the Swedish evaluation system. It is therefore of crucial importance to validate national measures of Swedish students' achievement with their ILSA test scores. Here, we offer results from such a validation study based on Swedish students' test scores in IEA's Trends in…

Development and use of validated assessments in physics provide insight into student understanding of physics concepts and can be utilized to track student learning across time and instructional strategies. These tools can be used to gauge the efficacy of interventions designed to support students and persistence, and allow instructors to make…

As we move further into the digital age, the acquisition of digital literacy (DL) and computational thinking (CT) skills is emerging internationally as an essential goal for students in contemporary school curricula. As the world becomes more uncertain and volatile due to impacts of artificial intelligence (AI), international unrest, climate…

Previous research on the implications of early-tracking education systems has not specifically focused on how studying in academic and non-academic tracks shapes the features and characteristics of shadow education (private tutoring) that students are involved in. The study compares the scale and features of private tutoring and the underlying…
