The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…

The purpose of the present study was to reveal the effectiveness of the Nature of Science (NOS) embedded in Argument-Driven Inquiry (ADI) instructional method on pre-service science teachers' (PSTs) content knowledge and self-efficacy in evolution theory. The study was a mixed-method study in which the qualitative data collection and analysis was…

It is generally accepted that a robust science education includes knowledge of science, as well as knowledge "about" science, or, in other words, an understanding of the "Nature of Science." However, debates around what Nature of Science is and how to measure it are far from settled, and this compromises our ability to support…

This study aimed to investigate research trends related to socio-scientific issues (SSI). The SSI articles analysed were from highest-rating five science education journals with the highest impact ratings, published between 2011 and 2022, including "Science Education" [SE], "Journal of Research in Science Teaching" [JRST],…

Teachers are key players in supporting the understanding of epistemological and social aspects affecting the development and validation of scientific knowledge, but they often hold inappropriate views of the Nature of Science (NOS), therefore hindering this understanding as an essential part of students' scientific literacy. To tackle this…

Although laboratory work is considered a significant factor in helping students develop their science process skills and cultivate alternative knowledge construction, there are still gaps in the selection, integration, and implementation of the basic elements in physics laboratories. In this study, three modified guided discovery and conventional…

This study investigated the effect of explicit nature of science (NOS) instruction and explicit argumentation instruction in socioscientific and scientific contexts, on students' NOS conceptions and their argumentation skills. Undergraduate students enrolled in two sections of a science content course were assigned into two groups: Socioscientific…

There is worldwide agreement that the understanding of the Nature of Science (NOS) is a critical component of scientific literacy. However, evidence indicates that both pre-service and in-service science teachers hold naïve views about NOS. Even so, the characteristics of pre-service teachers that influence their learning of NOS are not fully…

Computational approaches toward simulating chemical systems and evaluating experimental data has gathered great momentum in recent years. The onset of more powerful computers and advanced software has been instrumental to this end. This manuscript presents a hands-on activity which trains students in basic coding skills within the Matlab…

In previous published articles, formulae-based mnemonics by counting the total number of s bonds with a lone pair of electrons (LP), a localized negative charge (LNC), or a localized lone pair of electrons (LLP) and subtracting one (01) from this total value (TSLP, TSLNC, or TSLLP) to predict the power of the hybridization state of simple…

This study investigates the preservice elementary teachers' ability to use the components of an argument structure on a given science topic as well as the quality of the developed argument during their sophomore and senior year. In doing so, the study also aimed to discuss the effect of teacher education programs on the development of…

Both accurate monitoring and adequate control are crucial for effective self-regulation when learning from problem-solving tasks. Prior research has shown that self-regulated learning is especially harmful for low prior knowledge students, given their difficulties with accurate monitoring and control decisions. Although many studies have indicated…

Calls for undergraduate biology reform share similar goals: to produce people who can organize, use, connect, and communicate about biological knowledge. Achieving these goals requires students to gain disciplinary expertise. Experts organize, access, and apply disciplinary knowledge differently than novices, and expertise is measurable. By asking…

University lecturers stress the importance of science and non-science students developing informed views of nature of science. However, few previous researches have conducted to explore students' NOS views within specific majors. Consequently, this research used the questionnaire of VNOS-D (View of Nature of Science, the version D) to assess the…

This study examines the effectiveness of a teaching-learning sequence (TLS) to improve the understanding of the influences and interactions between a technology (mining) and society. The aim of the study is also to show the possibility of both teaching and assessing the most innovative issues and aspects of scientific competence and their impact…
