The study consisted of three articles. Article one aimed to determine if there were any significant difference in science graduate students' (SGSs') conceptions of the "consensus tenets" of the nature of science (NOS) with respect to demographic factors -- the SGSs' academic and research characteristics. The participants were SGSs from…

Scientific reasoning helps children understand the world around them. Teaching scientific reasoning can be challenging because not all component scientific reasoning skills develop at the same age and not all children learn these skills at the same pace. Adaptive support thus seems called for. We designed two types of adaptive instruction, based…

Active participation in project-based learning (PBL) could develop students` knowledge and crucial learning skills across various disciplines. However, the implementation of PBL in the K-12 classroom is usually impeded by the stepby-step PBL cycle. Micro project-based learning (MPBL), which advocates and adheres to the learning principles and…

Competencies for designing and evaluating scientific inquiries are a key emphasis in national curriculums worldwide and a focus of international large-scale assessment. Teachers globally are encouraged to provide learning opportunities for their students to explore and practice asking and conducting researchable questions. This study focused on…

Purpose: The purpose of this study was twofold: (a) to describe how the language diversity (i.e., the within-group variability in dual-language skills) of Latino dual-language learner (DLL) preschoolers was related to their science readiness skills and (b) to describe the importance of language of science instruction for Spanish-dominant children.…

Purpose: The purpose of this study is to examine how doctoral students in the biological sciences understand their research skill development and explore potential racial/ethnic and gender inequalities in the scientific learning process. Design/methodology/approach: Based on interviews with 87 doctoral students in the biological sciences, this…

This laboratory experiment introduces the fundamentals of electrochemical techniques to the undergraduate students by developing a simple and cost-effective miniaturized electrochemical setup for detecting UV-induced DNA damage. This is an imperative experiment, as it provides students first-hand experience with electrochemical techniques while…

Scientific abilities rubrics developed at Rutgers University are an assessment and self-assessment tool. They consist of tables, each representing a broad scientific ability (for example, "to collect and analyze data"), the listing of subabilities (for example, "independent and dependent variables are identified") and the…

Australian science teachers are asked to involve their students in the scientific processes of inquiry and investigation. The abilities needed for scientific problem-solving ("doing") and the capacity to reflect on the process of problem-solving at a meta level ("understanding") are defined as scientific reasoning competencies…

This article discusses a study carried out to investigate scientific reasoning skills among 82 science pre-service teachers at the Faculty of Education, Universiti Teknologi MARA (UiTM), one of the public universities in Malaysia. Undeniably, the development of general scientific abilities is critical to enable students of science, technology,…

This study focused on exploring and evaluating students' views of the Nature of Science in the context of undergraduate chemistry laboratory. Thirty-six undergraduate students doing a laboratory course in upper division physical chemistry were assessed using an open-ended instrument and assessment criteria that categorise them in three levels of…

Scientific reasoning competencies are highlighted in science education policy papers and standard documents in various countries around the world and pre-service science teachers are asked to develop them during teacher training as part of their professional competencies. In order to monitor the development of pre-service science teachers'…

Teaching the tools and concepts associated with modern physics can often be a daunting and difficult task for secondary science teachers. Classical physics is often perceived as intimidating and complex in its own right. Modern physics addressing quantum phenomena where Newtonian laws break down is even more abstract for learners. However,…

The study aimed to develop and validate an assessment framework of multidimensional scientific competencies for seventh-grade students in the northeastern region of Thailand. A total of 289 samples with three different scientific competency levels were randomly selected to participate as test-takers. The design-based research encompassing four…

In many nations, grades and standardized test scores are used to select students for programs of scientific study. We suggest that the skills that these assessments measure are related to success in science, but only peripherally in comparison with two other skills, scientific creativity and recognition of scientific impact. In three studies, we…
