Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

This study describes the role that Rasch measurement played in the development of assessments aligned to the "Next Generation Science Standards," tasks that require students to use the three dimensions of science practices, disciplinary core ideas and cross-cutting concepts to make sense of energy-related phenomena. A set of 27…

In 2020 a global pandemic forced biology teaching laboratories to move to remote instructional environments. In this article, we present data on student perceptions of laboratory instruction modality as experienced pre-, during, and post-pandemic. We designed a survey to evaluate students' perception of key components of scientific critical…

A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

An important goal of science education is for students to understand the nature of science. Science education has raised the question of what science is, how scientific knowledge is developed and how people participate in this process under the conceptual umbrella of 'nature of science' (NOS). This study aims to look at the effectiveness of the…

The Reaction Coordinate Diagram Inventory (RCDI) was developed to measure chemistry students' thinking and confidence when interpreting the kinetic and thermodynamic information encoded within reaction coordinate diagrams (RCDs). The RCDI was designed based upon analyses of qualitative data collected in semi-structured interviews with general…

This study addresses the use of epistemic criteria related to the scientific practice of inquiry in the context of environmental chemistry. In particular, it analyses the type of criteria that are used by pre-service teachers when assessing the adequacy of several scientific procedures for identifying microplastics in beach sand, as well as…

Research on student argumentation in chemistry laboratories has mainly focused on evaluating the quality of students' arguments and analyzing the structure of such arguments ("i.e." claims, evidence, and rationale). Despite advances in these areas, little is known about the impact of activity framing on the nature of student…

Although many studies have shown that reviewers particularly value the feasibility of a proposed project, very little attention has gone to how applicants try to establish the plausibility of their proposal's realization. With a sample of 335 proposals, we examined the ways applicants reason the feasibility of their projects and the kinds of…

Contribution: This article proposes a comprehensive graduate course on magnetic design that addresses existing gaps in current power electronics (PEs) education, provides theoretical foundations and hands-on skills, and matches syllabi coverage with current societal needs for electronic energy conversion. Background: A growing worldwide interest…

Scientific advances, particularly in evolutionary biology, genetics, neuroscience and artificial intelligence, present many challenges to religious and popular notions of personhood. This paper reports the first large-scale study on students' beliefs about the interactions between science and widely held beliefs about personhood. The paper…

In this research, the effect of authentic activities on the scientific process skills of 7th grade students was investigated. Research has been studied in a secondary school with 37 students in Turkey. In the research, authentic learning based education was carried out for 5 weeks in the 2017-2018 academic year. In this semi-experimental model,…

My problem of practice is that my learners were not learning and growing to their fullest potential in both content and necessary future ready skills -- 21st century and process skills to prepare them for postsecondary life outside of my classroom. I teach many high school learners with exceptionalities. I sought to alter my instruction and ensure…

Integrating decision-making learning goals within science classrooms has been increasingly common for science educators and researchers to help develop students' science literacy skills. These learning goals include understanding and applying scientific information as well as recognizing tradeoffs amongst multiple perspectives when decision-making…

This study examined the ways in which elementary science teachers notice, interpret and respond to students' sensemaking resources that students bring to school in the form of science toolkits. The science toolkits are comprised of three sensemaking resources: (1) ideas; (2) out-of-school experiences and funds of knowledge, and (3) youth genre.…
