A large body of research shows that using interactive engagement pedagogy in the introductory physics classroom consistently results in significant student learning gains; however, with a few exceptions, those learning gains tend not to be accompanied by more expert-like attitudes and beliefs about physics and learning physics. In fact, in both…

Many physics projects recently designed for high school teachers use Arduino as the main tool for managing sensors and data acquisition. This is a low-cost integrated development environment programmed with a simplified version of the C++ language. In comparison, the Raspberry Pi 3 platform, which also allows for the design of physics projects,…

This experiment combines analytical techniques of solid-phase extraction (SPE) and gas chromatography quadrupole time-of-flight mass spectrometry (GC-QTOF-MS) to determine organochlorine pesticides (OCPs) in river water as a means to develop and improve student understanding of the use of GC-QTOF-MS for qualitative and quantitative analysis. In…

This work aims to evaluate the evolution of chemical bonding concepts of high school students at public schools in southern Brazil. For this, we built the epistemological profile of each student who took part in a teaching-learning sequence (TLS) about this topic, based on the foundations of Bachelard's theory. Following the principles of the…

Organic electrosynthesis is an increasingly popular tool for driving and probing redox reactions. Recent advances in this field often employ an electrocatalyst to enhance the selectivity and efficiency of electrochemical reactions. A laboratory experiment was developed to introduce students to relevant mechanistic techniques in electrochemistry…

Highly efficient microwave-assisted organic synthesis is now commonplace in both industry and academia. Recently, a conductively heated sealed-vessel reactor was introduced that acts very similarly to a microwave reactor and is more affordable. Application of such reactors in teaching laboratories is advantageous because of the restricted window…

This study was aimed to develop a general argumentation framework for evaluating the quality of causal arguments across scientific and social contexts. We designed a computer-delivered assessment that contains four scenario-based argumentation tasks. Each task asks students to identify relevant evidence from provided data sources and use the…

Even though the educational researchers have developed and implemented various educational strategies to teach the concepts of the phases of the Moon and the formation of the lunar eclipse more effectively, many studies conducted by them in recent years reveal that the teachers still do not understand the causes and scientific processes related to…

It is widely recognised that science explorations is vital in children's lives as they make sense of the world. Now in its fourth edition, Science in Early Childhood provides a comprehensive and engaging introduction to science in the early years. Each chapter has been updated to include current research and to address changing priorities in early…

The purposes of this study were: To examine the effects of low-cost mini science experiment kits on Thai 6th graders' science learning achievement; To investigate how these kits impact Thai 6th graders' Science process skills; To explore their influence on Thai 6th graders' scientific mindset The participants were 111 sixth-grade students from…

Contribution: This study identifies the types of interaction that contribute to student learning with student-led tutorials (SLTs). The quality of these interactions include peer discussion, student tutor presentation, joint reasoning, and constructive feedback. Background: The introduction of SLTs in an advanced electromagnetics bachelor course…

As quantum technologies transition from the research laboratory into commercial development, the opportunities for students to begin their careers in this new quantum industry are increasing. With these new career pathways, more and more people are considering the best ways to educate students about quantum concepts and relevant skills. In…

This study systematically analysed, evaluated and synthesised published studies on 21stcentury skills and science achievement among secondary school students. By scouring 17 well-known online journal databases, 684 related studies were found. After the three-stage screening process, only 17 research papers were included in the study, which were…

Background/purpose: In the context of the Fourth Industrial Revolution, traditional teaching methods are insufficient for cultivating 21st-century competencies. In Vietnamese primary education, teaching Natural and Social Sciences is particularly challenging due to abstract concepts beyond the cognitive development of students aged 9-11. This…

An important research objective in modelling instruction is defining what students should learn about the model-referent relationship, as when unguided, they tend to errantly think of models as literal interpretations of their referents. Restating this problem we say students should learn about structure-preserving transformations between models…
