Skill-based outcomes play a prominent role in citizen science experiences as they are situated directly between the dual, intertwining goals of advancing science learning and science research. Regular and transparent assessment of volunteers' science inquiry skills can support these goals, but we lack a comprehensive understanding of how these…

The structure of many science programs at the college level assumes that students are able to draw on and integrate ideas from multiple disciplinary contexts. However, most assessment tools focus on learning in the context of a single discipline. We describe the development and validation of an instrument to measure how well students are able to…

Teachers' professional development (PD) is considered to be a topic of interest in science education. This study examines the impact of professional development in science pedagogy (PD in PED) on students' achievement and how it influences teachers' instruction based on the Trends in International Mathematics and Science (TIMSS) 2019. The sample…

Learners who pass the South African National Senior Certificate (NSC) physical sciences examination generally show a weak conceptual understanding of chemistry at university. This inconsistency was investigated by examining strategies used in the teaching of chemical equilibrium in schools. A combination of on-site observations, journaling and…

Barriers to learning can affect educators and students in achieving learning objectives. One of them is the epistemological obstacle caused by the limited context used when a concept is first learned. The purpose of this study was to explore the epistemological obstacles of mathematics students in the concept of limits and functions during online…

Organic qualitative analysis is one of the challenging chemical concepts in students learning of chemistry. The West African Examinations Council chemistry chief examiners for years, have lamented on students' poor performance in organic qualitative analysis at the senior high school level. This study, therefore, investigated chemistry students'…

The first educational goal within scientific subjects is to acquire a sense of scientific literacy. In science lessons, methods of scientific inquiry provide the tools to achieve this. In this study, we based scientific inquiry on the SDDS-Model according to Klahr (2002). It is divided into three subareas: Search Hypothesis Space, Test Hypothesis,…

Students in the physical sciences--physics and chemistry--often take multiple-choice exams for introductory courses. Some students will write a lot on their exams, while others write very little. Does the student doing more scratch work on their exam perform better than one who does not write as much? We analyzed multiple-choice exams in physics…

The ability to predict macroscopic properties using a compound's chemical structure is an essential idea for chemistry as well as other disciplines such as biology. In this study we investigate how different levels of interventions impact the components of students' explanations (claims, evidence, and reasoning) of structure-property…

A performance gap between the genders has been observed on the Force Concept Inventory (FCI) almost since its introduction. Many studies have sought to characterize this gender gap, however, few have tested the consistency of the factor structure across the genders. This study fills in this gap by offering the first piece of evidence that the…

The study aims to reveal students' mental models and perceptions regarding the concept of the celestial bodies, for instance, earth, sun, and moon. This research study was conducted as a case study focusing on qualitative data. This study also has used a sample formed of 5th-grade students, in the 2018-2019 academic year; the target sample is…

This study is a comparison of ground-based versus online student performance using a combination of common final examination scores and associated demographic data in a biological science college course taught by a single instructor. Multivariate and standard statistical analyses are used to examine data from five semesters of ground and online…

The study focuses on assessing the proficiency levels of higher education students, specifically the physics achievement test (PHY 101) at the National Open University of Nigeria (NOUN). This test, like others, evaluates various aspects of knowledge and skills simultaneously. However, relying on traditional models for such tests can result in…

This study examines how students' conceptual and procedural knowledge of chemical equilibrium is affected by technology-supported formative assessment (TSFA) strategies. This study's embedded/nested mixed method research design was used to achieve the study's objective. A random sampling method was used to choose the sample of two intact classes…

With the exponential increase of digital assessment, different types of data in addition to item responses become available in the measurement process. One of the salient features in digital assessment is that process data can be easily collected. This non-conventional structured or unstructured data source may bring new perspectives to better…
