The purpose of the study was to transforming chemistry learning from the textbooks in the silent classrooms to the school garden through activity-based learning with students' meaningful engagement in collaboration with the science teachers in the community schools in Nepal. This research also aims to clarifying the epistemological gridlocks…

Technological innovation in science provides complementary tools for exploring new teaching strategies within a pedagogical framework that promotes interaction between the teacher and the learner. This work is based on the implementation of a computer application modeling crystallographic material structures, in order to identify and study the…

This study examines scientific practices associated with scientific writing in organic chemistry in China. Although there is rapidly growing literature on the features and strategies of scientific writing, further research in this area is needed to recognize and treat scientific writing as a social endeavor to evaluate it in a more comprehensive…

Affect is associated with success and persistence in STEM courses and degree programs. Measurement tools that produce valid and reliable data are essential to capturing the impact of evidenced-based instructional practices and reformed curricula on learning. We report the development of the Achievement Emotions Questionnaire for use in…

Graphical representations are an important tool used to model abstract processes in fields such as chemistry. Successful interpretation of a graph involves a combination of mathematical expertise and discipline-specific content to reason about the relationship between the variables and to describe the phenomena represented. In this work, we…

Environmental pollution is both a worldwide and a local issue, and microplastic pollution in particular is receiving increased attention due to its prevalence and bioaccumulation potential affecting the food chain. This laboratory experiment uses current, research-based methods such that the students can determine the extent of microplastic…

Energy is considered both as a disciplinary core idea and as a concept cutting across science disciplines. Most previous approaches studied progressing energy understanding in specific disciplinary contexts, while disregarding the relation of understanding across them. Hence, this study provides a systematic analysis of cross-disciplinary energy…

The study aimed to investigate the effectiveness of problem-based learning (PBL) approach in enhancing the problem solving skills in Chemistry of Grade 9 students in a public high school in the Philippines. The level of problem solving skills of the students in the non-PBL and PBL group before and after their exposure to non-PBL and PBL approaches…

KinSim is a research-grade, interactive, user-friendly, open-source, and visual software for kinetics modeling of environmental chemistry and other applications. Students without any computer-programming background and limited knowledge of environmental chemistry can use KinSim, which also includes multiple features and functionality dedicated to…

Many studies have used the potential of computer games to promote students' attitudes toward learning and increase their learning performance. A few studies have transformed scientific content into computer games or developed games with scientific content. In this paper, we employed students' common misconceptions of chemistry regarding the…

The author discusses the history of the Molecular Education and Research Consortium in Undergraduate Computational Chemistry (MERCURY), which has made significant contributions benefiting science faculty and undergraduates. The peer review publication rate of 1.7 for MERCURY faculty is 3.4 times the average rate for physical science faculty at…

Many students consume energy drinks without knowing or thinking about the adverse side effects. The purpose of this article is to share student procedures and results after testing the effects of a popular energy drink, Red Bull, on Dugesia Dorotocephala planarians (flatworms). Planarians are animals with neurotransmitters systems that are similar…

Science and storytelling have an uneasy relationship. The scientific community frequently disdains stories, seeing them as polluting the purity of objective communication of data. In the peer-review process, for example, scientists who tell stories with their data are seen as "embellish[ing] and conceal[ing] information to evoke a response in…

The Additive Factor Model (AFM) is a cognitive diagnostic model that can be used to predict student performance on items in a context that allows for student learning. Within AFM, "skills" have a learning rate, and student acquisition of a skill depends only on the number of opportunities a student has had to exercise that skill and the…

This study examined the teacher effectiveness of the selected STEM subjects' teachers of physics, chemistry, and biology at the senior secondary school level in Ijebu North local area of Ogun State, Nigeria. All the fifty teachers delivering the selected STEM subjects were observed using and adapted Teachers' Effectiveness Observation Guide…
