A sequential exploratory mixed methods approach guided research on the science program infrastructures (SPI) of a sample of 28 high schools representing 1,370 high schools in a large southwestern state. Comparisons of SPI were made between and among schools representing highly successful schools of low (n=9) and high diversity (n=10) with less…

This paper is based on a systematic literature review of published research on the educational application of Virtual Lab. The paper focuses on the use of the mobile Virtual Lab application for learning science practicals in rural school context. This paper analyses the theoretical aspects of using VL in teaching and learning of science practical…

Context-Based Learning (CBL) and learning through developing and using models are two important teaching approaches for chemistry conceptual understanding. We aimed to examine the influence of a CBL approach on students' understanding of Multiple Models of Knowledge Representations ("MMKRs") and "multiple molecular…

One of the obstacles that occur in Chemistry learning is low student motivation due to monotonous media. Another thing that currently becomes an obstacle is the COVID-19 pandemic which limits face-to-face learning. However, Chemistry practicum learning in the laboratory is difficult to carry out at students' homes. The purpose of the study is to…

This work documents the collaboration between the Physics department of the University of Calabria and some schools of the region in a project devoted to recovering disused instrumentation in school laboratories. The project has been conceived as a workplace experience for the students, i.e. a learning experience in a real work place. In Italy,…

The development of science writing and presentation skills is necessary for a successful science career. Too often these skills are not included in pre- or postsecondary science, technology, engineering, and mathematics (STEM) education, leading to a disconnect between high schoolers' expectations for college preparedness and the skills needed to…

Using Bruno Latour's framework of a "collective of humans and nonhumans", this paper presents an analysis of chemistry instruction in a high school curriculum and professional development setting to present the chemistry education community with a new way to think about reality and knowledge construction and, at the same time, to…

The effective use of formative assessment (FA) has been demonstrated to confer positive impacts on student learning. To understand why and how FA works, it is necessary to characterize teachers' FA practices, but because both teaching practice and learning depend on the nature of the discipline, there are disciplinary aspects to examining this.…

The basic concepts inherent to statics, including unbalanced and balanced forces and instability and stability of physical systems, have traditionally been covered in middle and high school physical science courses (Physical Science as indicated in "Next Generation Science Standards"). Yet, these concepts are covered using a physical…

With the developing technology educating students free from misconceptions, making sense of their learnings and using them in daily life are primarily aimed. This research is designed not only for teaching "work, energy and power" concepts and the relationships among them but also for investigating the effects of the teaching on…

Geodesy is a very active and essential research discipline in geophysics but it is not a commonly studied subject at the secondary school or junior post-secondary levels. Far more frequently, gravity and gravitational acceleration are discussed, to some extent, in elementary kinematics or classical mechanics courses. This often takes the form of…

We present a critical discussion of how chemistry textbooks treat the electrolysis of water and aqueous salt solutions, based on a survey of general chemistry textbooks in English and Korean at secondary and tertiary levels, also informed by the historical background of 19th-century debates. English-language textbooks present various and…

Science Hunters is a UK outreach project that uses "Minecraft" (a computer game that allows children to build with a wide range of blocks) to engage children with science. Sessions are based on a range of science topics and include practical activities. A new topic, on bioluminescence, was designed in collaboration with staff and…

Graphs are often used to represent mathematical functions, to illustrate data from social and natural sciences, or to specify scientific theories. With increasing emphasis on the development of scientific research skills, the work with graphs and data interpretation are gaining in importance. The research involved an eye-tracking experiment…

First-year undergraduate curricula and their delivery should assist students in the transition from previous learning experiences to learning in higher education. However, the so-called articulation gap or discontinuity between secondary and higher education has been identified as a key structural curriculum problem for first-year success in South…
