The Lawson classroom test of scientific reasoning is a quite popular and widely used tool that measures the level and development of the student's scientific reasoning skills. In this contribution, the results of this test for the N=446 students of the Faculty of Science Palacký University Olomouc from the years 2018-2020 at the beginning of their…

During the Cultivating Diverse Talent in STEM (CDTIS) Project, a team of scientists, teachers, and a researcher developed a performance-based assessment of high school students' creative problem-solving skills and ability to apply physical science principles in practical ways. It was one of six measures to identify exceptionally talented students.…

Concept inventories (CIs) are commonly used in pre-post instruction to study student conceptual change. For consistency in assessment interpretation, a CI's assessment construct is desired to maintain invariance across different test times. In this study, the longitudinal measurement invariance (LMI) analysis under the confirmatory factor analysis…

In many educational systems, textbooks are a leading factor for daily instructional practices, and consequently may affect educational outcomes. Whereas in many countries textbook assessment is a common practice in light of evaluating and improving educational effectiveness, in other countries these practices are absent, mainly under the realm of…

We describe the conceptualization, design, development, validation, and testing of a summative instrument that measures high school students' ability to analyze and evaluate data, construct scientific explanations, and formulate scientific arguments in biology and chemistry disciplinary contexts. Data from 1,405 students were analyzed to evaluate…

In the Italian education system, secondary students (ages 14-19) are confronted with the foundations of quantum physics during the final term of scientific high school (pre-university year). The Italian Ministry of Education, University and Research (acronym MIUR) has remarked its importance in the syllabus to address the high school exit…

The purpose of this study was to investigate not only the effectiveness of dynamic versus static visualizations on learning star motions but also the influence of students' spatial abilities with these two types of visualizations on their learning. We assigned 155 fifth-grade students to either a dynamic or a static condition. We used a science…

On the basis of the results of two prior studies at the US Naval Academy (USNA), which described the choice of study resources and the self-reported learning approaches of students of differing achievement levels, the current investigation examines how students of differing achievement levels in general chemistry actually solve multiple-choice…

The use of spaced repetition within a physics higher education thermodynamics module has been analysed for: its pattern of use by students; its effect on memory and performance in the end of module exam; and performance in a delayed test after the summer vacation. A custom-built web app with the facility to generate a personalised repetition…

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…

This research was conducted to facilitate the conceptual understanding of the solutions that contain abstract concepts and not to understand easily. The aim of this research is to determine the effect of applied methods on the achievement level of prospective science teachers and conceptual understanding level at the particulate nature of matter…

Relationships play a strong role in rural communities and education, and multiplex relationships--relationships that can overlap due to multiple contexts of interaction in a rural school--are unique to the rural setting. This study focused on multiplex relationships and their impact on science classroom performance, as measured by science…

Research on the test structure of the Force Concept Inventory (FCI) has largely been performed with exploratory methods such as factor analysis and cluster analysis. Multidimensional Item Response Theory (MIRT) provides an alternative to traditional exploratory factor analysis which allows statistical testing to identify the optimal number of…

ACS Examinations provide a lens through which to examine historical changes in topic coverage via analyses of course-specific examinations. This study is an extension of work completed previously by the ACS Exams Research Staff and collaborators in general chemistry, organic chemistry, and physical chemistry to explore content changes in the…

In this study, we analyze the systematic error from false positives of the Force Concept Inventory (FCI). We compare the systematic errors of question 6 (Q.6), Q.7, and Q.16, for which clearly erroneous reasoning has been found, with Q.5, for which clearly erroneous reasoning has not been found. We determine whether or not a correct response to a…
