A material commonly known as Flubber, with properties that are excellent for teaching about glaciers, has been widely used in geosciences education. Yet, the original recipe contains borax, which has health risks that should be avoided. A new recipe is shared containing low-cost, readily available ingredients that produces a reformulated Flubber…

This study aims to evaluate the effectiveness of concept maps on science achievement among elementary and secondary education students, including low-achieving students. A systematic search located 55 studies about concept mapping in science achievement published in peer-reviewed journals and dissertations between 1980 and 2020. We extracted 58…

Sustainability has a molecular basis that suggests a central role for chemistry in addressing today's challenges to Earth and societal systems, and this role requires educators to see chemical reactions and processes as integral parts of dynamic and interconnected systems. Despite this prospect, few accessible resources are available for students…

The question of precollege physics access and performance has been a persistent concern when considering the goal of diversifying participation in post-secondary STEM study and careers. This observational study examined school-level academic and demographic predictors of high school physics enrollment and performance in the USA. Due to the…

This study was aimed at assessing the research trends in the family resemblance approach to the nature of science (FRA-to-NOS). This was accomplished through bibliometric analysis using the R program and a literature review employing the analysis framework. The findings demonstrated that the field of FRA-to-NOS has been experiencing growth, with…

O•, O[subscript 2] and O[subscript 3] play vital roles in the Earth's atmosphere, regulating ultraviolet radiation from the Sun and being essential for life. However, the oxygen family, O•, O[subscript 2] and O[subscript 3], also provides a source of the HO radical, the atmospheric detergent that removes pollutants from the atmosphere. This…

This study examines and describes how various online remote laboratory courses, necessitated by the COVID-19 pandemic, were implemented at Hankuk University in Korea in 2020. We compared four general undergraduate laboratory courses, one each for physics, chemistry, biology, and earth science, and two major-level laboratory courses taught during…

Much of the focus of international comparative studies of students' achievement has been on New Zealand students' falling standards. Using the most recent findings from the Trends in International Mathematics and Science Study (TIMSS), and, in particular, Year 9 New Zealand students' performance in specific items, this article suggests that there…

Active learning classrooms (ALCs) are designed to support collaborative learning in large class sections that are often taught with a lecture format. Studies on ALCs indicate that they have positive influences on student learning, but the same studies fail to look at learning differences between subgroups of students. In the current study,…

Background: The goal of this research was to determine students' perceived self-efficacy in science classes through involving students in expanding disciplinary core idea (DCI) and interdisciplinary core idea (ICI) maps, as a method to visualize knowledge (utilizing mind mapping and concept mapping) to support students to integrate…

The innovation calls insist on the fact to identify new forms and models of learning and teaching. Actually, the educational approaches that encourage effective learning among student, is the Investigative Approach, which demonstrates more and more its potential in teaching. It is a scientific approach based on questioning and investigation where…

Rarely are scientific phenomena isolated to a single discipline such as biology, chemistry, physics, Earth science, or others. Rather, these phenomena span multiple disciplines and often require bringing together content and understandings from multiple disciplines to engage with or explain the target phenomena. This study uses a model-based…

The manufacture of metal alloys is ubiquitous, yet infrequently discussed in high school coursework as concepts related to them are often too complex or abstract for beginning science students. However, earlier introduction to metallurgy in classroom settings could promote interest in practical applications of chemistry, physics, and geology due…

Research has shown the highest level of understanding in the geosciences to be the ability to think about the Earth as a dynamic system. The Earth system contains four spheres: the geosphere, the hydrosphere, the biosphere, and the atmosphere. These spheres are linked through the biogeochemical cycles that move matter and energy through the…

In a series of 12 project-based learning lessons, a group of seven fifth-grade students who live 200 miles from the coast explored their personal connections to the ocean. After completing a unit on the role of water in Earth's surface processes, the students investigated ocean acidification and how this pervasive ocean problem impacts their local…
