Dimensionality reduction techniques are essential in analyzing large 'omics' datasets in biochemistry and molecular biology. Principal component analysis, t-distributed stochastic neighbor embedding, and uniform manifold approximation and projection are commonly used for data visualization. However, these methods can be challenging for students…

The use of data to explain natural phenomena has been a core feature of science education, and science educators continue to call for an increased emphasis on teaching data practices. This mixed methods design-based research study adds to the growing body of research on data practices in science by explaining the learning trends of science…

Reform efforts in K-12 science education have been gaining pace ever since the introduction of the "Next Generation Science Standards" (NGSS). The new vision calls for reconsidering teacher preparation programs to prepare future teachers who are confident and competent in delivering NGSS-based instruction. This study investigated the…

This paper will provide several examples of science and mathematics integration: navigation/map-reading, ecology/ecosystems/population growth, and chemistry/molecular structures. This paper underscores integrating STEM subjects with problem-based learning with technology such as video/computer simulations/programming/coding and the dynamic free…

K-12 education as an enterprise always has two main aims; to teach basic skills and knowledge and to cultivate moral citizenry. There is substantial evidence that empathy can promote morality and character development through education. To shed light on what has been done and to identify the pathways already established, a thematic review of…

This study assessed the efficacy of the spaced learning method compared to the activity-oriented method in improving chemistry achievement among high school students, focusing on different cognitive domains. An experimental design involving pre and post-test control groups was employed, with 106 students from two schools participating. The…

Investigating definitions of success and failure among introductory biology students is essential for understanding what underlies their self-efficacy; a student who gets a B on an exam may lose self-efficacy if they define failure as anything less than an A. Yet, whether students have the same definitions for success as they have for failure in…

Despite problem solving being a core skill in chemistry, students often struggle to solve chemistry problems. This difficulty may arise from students trying to solve problems through memorising algorithms. Goldilocks Help serves as a problem-solving scaffold that supports students through structured problem solving and its elements, such as…

General education science courses at a Canadian postsecondary institution implemented "Beyond Labz" virtual science labs. Faculty members teaching vocational science-related courses tested this resource. This qualitative study explores faculty member and learner perceptions of the efficacy of these virtual labs in terms of ease of use,…

This article deals with visual representations of children in social and natural science primary education textbooks from Spain and Portugal during the final years of dictatorship, transition to democracy, democratic consolidation, and democracy between 1965 and 1995. It explores ways in which children are addressed and made visible in social and…

We created a 2-week, dual-module summer course introducing high school students to environmental toxicology by teaching them quantitative polymerase chain reaction (qPCR) as a way to quantify gene expression of chemical defense proteins in response to exposure to environmental pollutants. During the course, students are guided through the various…

This study investigated how pre-service teachers perceive and plan to use a virtual reality classroom for science teaching during microteaching practices. The UTAUT 2 model was adopted as the conceptual framework for this study. Data were collected through an online survey from eighty-three pre-service science teachers from a large metropolitan…

One agenda of science instruction in primary schools is to develop learners' scientific reasoning abilities and to equip them with the necessary twenty-first-century skills. Few studies have been conducted to develop measurement tools that aspire to assess primary school learners' scientific reasoning. Most of these studies lack a theoretical…

Laboratory classes effectively enhance student understanding and appreciation of course concepts. With course delivery suddenly shifted into the online format due to the COVID-19 pandemic, four laboratory exercises in each of two introductory-level soil science courses were converted into virtual sessions delivered in the form of…

With the onset of COVID-19, colleges and universities moved to emergency remote teaching, and instructors immediately adjusted their curricula. Many instructors adapted or developed new online lessons that they subsequently published as Open Educational Resources (OERs). While much has been examined related to how entire course designs evolved…
