The potential of science to transform lives has been highlighted by a number of scholars. This means that critical socio-scientific issues (SSIs) must be integrated into science curricula. Development of context-specific scientific knowledge and twenty-first-century learning skills in science education could be used to address SSIs such as…

The purpose of this study is to determine the impact of computer-animated concept cartoons and outdoor science activities on creating awareness among seventh graders about light pollution. It also aims to identify the views of the students on the activities that were carried out. This study used one group pre-test/post-test experimental design…

The study investigated the influence of students' gender on their understanding, application and analysis of Light waves concept in physics in Ikwerre Local Government Area of Rivers State, Nigeria. A quasi-experimental pretest-posttest design comprising of three experimental and one control group was used, each group was taught with a different…

Making decisions about the production and use of chemical substances is of central importance in many fields. In this study, a research team comprising teachers and educational researchers collaborated in collecting and analyzing cognitive interviews with students from 8th grade through first-year university general chemistry in an effort to map…

The purpose of this study was to investigate the effect of teacher guidance on the quality of collaborative argumentation in middle level classrooms. Each of six science classes was randomly assigned to either the intervention (teacher guidance) or control condition (minimal teacher guidance). The verbal collaborative argumentation that occurred…

Remote access technologies enable students to investigate science by utilizing scientific tools and communicating in real-time with scientists and researchers with only a computer and an Internet connection. Very little is known about student perceptions of how real remote investigations are and how immersed the students are in the experience.…

To attain the goal of scientific literacy, the nature of science (NOS) is one of the areas that should be addressed. In many countries, the training of scientifically literate generations is a fundamental aim of science education, as a result there is an emphasis on NOS in science curricula and curricular materials. Textbooks prepared to teach…

In this study, two groups of 11th grade chemistry students (n = 210) performed a sequence of hands-on and virtual laboratories that were progressively more inquiry-based. One-half of the students did the laboratory sequence with the addition of a teacher-led discussion connecting student data to student-generated visual representations of…

The purpose of this study was primarily to explore high school students' cognitive structures and to identify their learning difficulties on ethanoic acid through the flow map method. The subjects of this study were 30 grade 1 students from Dong Yuan Road Senior High School in Xi'an, China. The interviews were conducted a week after the students…

This study investigated the effects of students' prior science knowledge and online learning approaches (social and individual) on their learning with regard to three topics: science concepts, inquiry, and argumentation. Two science teachers and 118 students from 4 eighth-grade science classes were invited to participate in this research. Students…

Improving high school physics teaching and learning is important to the long-term success of science, technology, engineering, and mathematics (STEM) education. Efforts are currently in place to develop an understanding of science among high school students through formal and informal educational experiences in engineering design activities…

Nanoscale science and technology (NST) is an important new field in modern science. In the current study, we seek to answer the question: "What are the essential concepts of NST that should be taught in high school"? A 3-round Delphi study methodology was applied based on 2 communities of experts in nanotechnology research and science…

The purpose of this study was to determine teachers' attitudes, values, and beliefs about inquiry. The participants of this study were 275 middle grade and secondary science teachers from four districts in North Carolina. Issues such as class size, accountability, curricular demands, and administrative support are perceived as constraints,…

Currently, there are a number of educational applications that allow students to reinforce theoretical or numerical concepts through an interactive way. More precisely, in the field of the analytical chemistry, MATLAB has been widely used to write easy-to-implement code, facilitating complex performances and/or tedious calculations. The main…

We describe a laboratory experiment that employs the Nanoceria Reducing Antioxidant Capacity (or NanoCerac) Assay to introduce students to portable nanoparticle-based paper sensors for rapid analysis and field detection of polyphenol antioxidants. The experiment gives students a hands-on opportunity to utilize nanoparticle chemistry to develop…
