Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

In the teaching and learning of physics, simulations have many applications. Simulations can help to illuminate concepts (such as the motion of electrons in electric or magnetic fields) that cannot usually be seen with the unaided eye, or to slow down things that happen over short time periods or at high speeds. They can also be used to help…

Learning to create, use, and evaluate models is a central element of becoming a scientist. In physics, we often begin an analysis of a complicated system with highly simplified or toy models. In introductory physics classes, we tend to use them without comment or motivation. Some students infer that physics is irrelevant to their understanding of…

We developed new teaching materials, electrical resistors and capacitors, using carbon nanotube (CNT) paper and carbon fibre (CF) paper to foster students' creative thinking, thereby deepening and extending learning. Using a CNT-paper electrical resistor, it is possible to elucidate the dependence of the resistance value on the length and width.…

In science learning, the experiment is an essential activity to facilitate students to discover and develop knowledge as well as to enhance scientific process skills and self-confidence. This study aims to create a simple experimental apparatus related to the principle of fluid continuity that can be made and conducted by the teacher and student…

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…

This study investigated the introduction of the second law of thermodynamics using the Legitimation Code Theory (LCT) (semantic waves) among first year chemistry students. The aim of the study was to investigate the extent LTC (semantic waves) reduce the entropy concept's complexity and abstractness when introducing the second law of…

This study provides a partial-credit scoring (PCS) approach to awarding students' performance on multiple-choice items in science education. The approach is built on "fundamental ideas," the critical pieces of students' understanding and knowledge to solve science problems. We link each option of the items to several specific fundamental…

The present study aims to find out the agreement rates of students on non-scientific ideas concerning the concept of magnet with a cross sectional survey. A total of 436 students studying in the final years of elementary (n=113), middle (n=110), high school (n=105) and university (n=108) participated in the study. Data were collected with the help…

The 2019 published report of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem (IPBES) reveals that the decline in species and habitats induced by human activities is continuing. School students still have difficulties to understand the meaning of biodiversity and the consequences of its loss. The underlying assumption of…

Many introductory astronomy courses include concepts related to basic stellar properties. In general, these are concepts that originate from the human perception of starlight. This observational aspect is not easy to incorporate in the classroom. We explore if these concepts could be developed using the built-in data in a planetarium software.…

In the US, undeniable evidence shows that socioeconomic inequities explain a high proportion of individual differences in school achievement. Although not all countries show this same effect due to socioeconomic status, it is consistently found that social inequities lead to achievement gaps. These achievement gaps then manifest into trajectories…

We report the results of a study on high school student difficulties in drawing the magnetic field lines for two magnets facing each other. Student difficulties were investigated by means of a predict-observe-explain activity. Our data confirm some of the previous results from the educational research literature on student difficulties in drawing…

The article presents our Inquiry-Based Learning (IBL) activities in the project-based Science education of third graders (8--9-year-old pupils) in the Slovak Republic. Individual tasks of project assignment titled "Temperature Measurement" were conceived for "guided inquiry". We also supported the IBL of pupils by interactive…

This paper explores the effect teachers' participation in a targeted inquiry-based/nature of science (NoS) continuing professional development programme had on Irish primary children's experiences of scientific inquiry and developing conceptions of NoS. Data were gathered from 459 children from 10 Dublin schools. The findings revealed that their…
