Analogies can be powerful teaching tools because they can make new material intelligible to students by comparing it to material that is already familiar. In assisting students to understand chemistry concepts, teachers occasionally use analogies. These analogies are believed to help the students to structure the new knowledge and they are…

Estimation of soil texture is an essential skill for soil scientists, but a difficult skill to learn. We compared two approaches for teaching soil texture: the traditional flowchart approach and an experimental self-calibration method. Three lab sections of an introductory soil science class were assigned to learn by the flowchart method (n = 60)…

Teaching and learning introductory thermodynamics has drawn considerable research attention over the last two decades, especially in several disciplines of higher education. Under particular investigation is the First Law of Thermodynamics (FLT), which offers an expression of energy conservation in thermodynamic systems, as the evidence shows that…

When teaching a general education introductory astronomy course that includes a mathematics prerequisite, it is important to convey that formulas and equations physically represent properties of actual objects and processes that occur that can actually be observed. Students with varying comfort levels with mathematics often need to be convinced…

The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

Our past experiences in science teacher education inferred that using scientific practices in science teaching courses and supporting pre-service teachers' efforts to integrate these into their teaching allow them to gain confidence in analysing and interpreting empirical data. However, those efforts sometimes do not provide sufficient help for…

This study aimed to investigate the effects of robotic coding supported Design-Based Science Instruction (RC-DBSI) on sixth-grade students' science process skills. One-group pretest-posttest experimental design was employed in the study. Participants consisted of thirty-nine sixth-grade students enrolled in a public middle school located in the…

The CRISPR/Cas9 system is widely used for editing genes in various organisms and is a very useful tool due to its versatility, simplicity, and efficiency. To teach its principles to post-graduate students we designed a laboratory activity to obtain and analyze PDS3 mutants in "Arabidopsis thaliana" plants consisting of: 1) Design of…

It has previously been suggested that there is a need for a more language focused science instruction, especially in linguistically diverse classrooms, where many students are second language learners. But it has also been suggested that teachers may feel uncertainty about how to teach in ways that promote learning of both subject matter and…

Natural science itself is an experimental science, so practice and experimentation are important and are typical teaching methods of this subject. To make practice and experiment play the highest strengths in teaching and developing the ability to learn about nature - one of the three specific competencies of natural science, the association of…

This paper presents a perspective of how the radiation and radioactivity themes have been discussed at the high school level in several locations around the world. In this context, scientific journals, academic journals, theses, dissertations, and media materials were analyzed. Recent research has shown that the concern with the discussion about…

Analogies are bridges between prior knowledge and new knowledge to make meaning of the new one. Analogies are particularly effective in teaching science concepts that are not very apparent in the students' everyday lives due to their abstract nature. For this reason, it is essential to adapt analogies to teach new concepts effectively in science…

Science is a systematic study of natural phenomenon. The natural phenomenon is perceived and understood by an individual based on his/her experience and cultural context. The term misconception is complex in nature and has been conceptualize as alternative conceptions, preconceptions, alternative ideas, conceptual stumbling blocks, erroneous…

This is a qualitative, descriptive, and multi-case study, in which the researcher investigated the perceptions of middle school teachers who were implementing three-dimensional learning aligned with the Next Generation Science Standards (NGSS) into their instructional practices. The participants were 10 middle school teachers who worked in three…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…
