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…

In his high school science classes, author Jonathan Bergmann employs "flipped-mastery learning," an equity-driven method that empowers students to master core material at variable paces and develop skills of self-directed learning. As schools face pandemic-related learning loss, Bergmann streamlines the logistics of an approach that…

Communication skills are crucial in 21st century education since they encourage other skills, such as speaking skills, critical thinking, and creative thinking. Communication skills are a means to create, maintain, and expand knowledge in science learning. This study explores the profile of students' communication skills in science learning in…

This study focuses on an educational game titled "Cellverse," a two-player cross-platform VR project intended to teach high school biology students about cell structure and function. In "Cellverse," players work in pairs to explore a human lung cell and diagnose and treat a dangerous genetic disorder. "Cellverse" is…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

This article describes the use of literature to broaden students' skills in content comprehension, data analysis, modeling, and productive scientific discussion. The design builds on existing models to maximize student gains in ability, confidence, and postgraduate preparation. Course units are divided into 1-week modules consisting of three…

This research is aimed to investigate the current implementation of the Science Spiral Curriculum from the perspective of the Science Teachers in the city of Baybay, Leyte. Descriptive-evaluative research design was used. This study was conducted in five selected Secondary High Schools in Baybay City Division. The respondents of this study were…

Complementing biology lecture courses with laboratory sections is nearly universal at undergraduate institutions, yet many topics in biology do not easily lend themselves to experiment-based laboratory activities. Topics such as comparative anatomy, evolution and systematics are often taught as passive, observation-based laboratories. In this…

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…

Purpose: Educators increasingly rely on student survey data to assess classroom climate and implementation of ambitious new teaching standards. Aggregates of student survey reports have face validity as indicators of typical student experiences and can reliably distinguish among classrooms and predict valued student outcomes. Investigating…

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…

In this paper we argue that the complexity of education systems can lead to a lack of coherence in the implementation of policy. More effective educational change requires policymakers and researchers to pay more attention to supporting teachers in classrooms. As an example, we consider decades of research attempts in STEM education to implement…

This study investigated the effect of applying "participant modeling" followed by a role play on grade eleven scientific students' achievement and motivation in biology. Students usually face problems in understanding difficult biology concepts like Krebs cycle which is composed of a series of biochemical reactions with many molecules…

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…
