Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

The study was focused to explore the use of virtual world of computer in Biology experiments to foster the students' problem-solving skills (PSS). The study was made on explanatory sequential mixed method design which included quantitative (true-experimental) approach was followed by qualitative (interview protocol) method. Population of the study…

Engagement can be situative and, when it occurs, a number of experiences will co-occur. The present study examined the co-occurred experiences of optimal learning moments (OLM), a type of situated engagement, using the novel network analysis and including data from two countries: Finland and the US. Both samples were from high schools and were…

Sustaining a broad diversity of plants is key for a sustainable future. For instance, providing a variety of flowering plants in urban and agricultural landscapes mitigates the current decline of pollinators and biodiversity in general. Therefore, educating about the diversity of flowering plants has high current relevance for biology and…

This article focuses on integration of the technology of iSENSE into the secondary education as a teaching and learning tool to design, develop, and infuse digital learning experiences that utilize technology. The objective of each lesson was to use this application to achieve redefinition, create new tasks previously inconceivable, and transform…

Being able to learn from failure is a fundamental skill for a scientist, as scientists often learn from failure in practical work by trialling and refining experimental designs, improving calibration techniques, and hypothesising and testing expected outcomes. This qualitative, practice-based study describes how junior secondary science teachers…

Although there is a push to provide more student agency in science classrooms, teachers and students may become frustrated when inquiry activities and equipment do not work as planned--teachers because of the time crunch to "cover" topics and students because of the perceived lack of value in activities that are "off task." In…

Science textbooks often include text and diagrams to aid learner understanding. Yet traditional written instructions in textbooks often separate them, which can increase cognitive load and hinder effective learning. This research proposes and tests a novel presentational format for written instruction that incorporates spatial contiguity, numbered…

About 30 years ago I taught a series of summer enrichment programs for high school physics teachers, using funding from the Howard Hughes Medical Institutes. I deliberately chose teachers from smaller cities and towns who were unlikely to have contact with other physics teachers. One of my more interesting teachers came from a rural area in a far…

There is currently a lack of systematic study examining the integration of verbal-visual elements in science textbooks. In particular, few research has investigated how different types of visual representations (e.g. photograph, diagram, table) vary across the major written genres of science (e.g. information report, explanation). Based on the…

This study focuses on the perceived gap between the required and actual level of digital research skills (DRS) of students entering tertiary science education. By combining existing frameworks for research skills and digital literacy skills, a guiding framework of DRS was constructed. The DRS framework incorporates seven categories and is…

The Arduino microcontroller is currently one of the favorite tools of makers, and many teachers have used it in teaching or experiments. In addition, light-emitting diode (LED) smart lighting is the worldwide trend in lighting. There are many teaching demonstrations or applications of color addition using LEDs. Furthermore, the Internet of Things…

In this paper, we discuss a demonstration we have been performing for years with students from different levels, from physics students from our university to high school students in some talks aimed at encouraging them to study science. It provides visualization of Brewster's angle in an ingenious way using a "loaded" liquid crystal…

In this work, we introduce high school students to renewable energy through the exploration of the pyrolysis process, focusing on the conversion of lignocellulosic biomass into bio-oil. Students undertake a sequence of straightforward experiments in four sessions, using a handmade reactor and various types of biomasses. Outcomes such as yield…

In the course of combining the Sustainable Development Goals (SDGs) with the science education curriculum, the relevance of the micro- and macroalgae in education is based on the biotechnological future-oriented significance and the ever-growing trend toward plant-based nutrition. So, the micro- and macroalgae are finding their way onto the food…
