The aim of this study was to investigate the effectiveness of scenario-based multiple-choice questions to assess students' science process skills. To achieve this objective, a test with 32 scenario-based multiple-choice questions evaluating students' skills in formulating hypotheses and identifying variables was prepared and administered to 370…

Assessment instruments that generate quantitative data on attributes (cognitive, affective, behavioral, "etc.") of participants are commonly used in the chemistry education community to draw conclusions in research studies or inform practice. Recently, articles and editorials have stressed the importance of providing evidence for the…

This study aims to design an educational process for teaching scientific concepts during the preschool period based on the instructional design model of Seels and Glasgow and to evaluate its effectiveness. For this purpose, a material set incorporating a teacher's manual and interactive holographic materials was developed. The teacher's manual…

Generic skills are fundamental skills needed to complete a job or project that can be grown when students go through the learning process. This study aims to analyze and identify students' general skills in terms of scientific literacy through research-based learning methods in the Science Application course. The research uses a quantitative…

Most undergraduate students do not have practical experience working with model organisms despite having theoretical knowledge of their importance. This practical was developed to offer students experience working with three species of nematode, including "Caenorhabditis elegans." In the first task, students prepare slides of three…

This study explored how peer feedback after hands-on scientific inquiry (SI) activities affected students' SI competence over time (6 weeks) by implementing an after-school intervention program in which 188 Chinese ninth-grade students (14-16 years old) participated during their first semester. A between-subject experimental design was used for…

Limited research examines the critical intersection between science and special education (SPED), particularly on the nature of science (NOS) in science methods courses. This study addresses this gap by investigating 10 preservice SPED teachers' NOS understanding, NOS implications for SPED, and the integration of NOS into their lesson plans in a…

The purpose of this multiple case study was to explore affordances for STEM-related skills in a nature preschool in central Texas. Observations were conducted along with the collection of videos and photographs of four preschool-aged participants. Informal interviews were also implemented during data collection and observations. Semi-formal…

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…
