Missing data is a regular issue that researchers and practitioners must consider for treatment. Commonly, cases for which data is missing are excluded from inclusion in larger data sets. However, this is not the only option and could artificially alter the sample. Other options are available for imputing missing data. Expanding on work previously…

Recent work has shown that retrieval hints can make test trials more enjoyable without sacrificing learning. We investigated the extent to which this effect was moderated by hint strength. Both experiments utilized a within-participants design. In Experiment 1 (n = 41), participants studied skeletal charts highlighting a bone region. After study,…

Computer Based Testing has become a prominent method in student assessment in Nigeria and student perception on this testing technique is paramount. This study examined the perception of undergraduate students towards computer based testing by comparing several modules studied by Undergraduate students in Nigeria which constitutes a major gap in…

This study aims to determine Turkish high school students' misconceptions about the electric charge imbalance by using a four-tier misconception test, where the main questions are accompanied by a question about the reason for the answer, as well as student declarations about their degrees of certainty. A four-tier electric charge imbalance…

The purpose of this research was to explore the coherence and effectiveness of an assessment approach that combined principles of cognitive-based assessment, performance assessment, and the Next Generation Science Standards. By drawing on research on learning progressions and cognition in geoscience to design, implement, and analyze an Earth…

Several studies compared three different types of questions (conceptual, algorithmic, and graphical) across various topics, however, few focused specifically on gifted students. This study addressed this gap. The aim of the study, hence, was to determine whether there were notable differences in gifted students' performance in the three types of…

This study proposes an online practicum model supported by Wireless Sensor Network (WSN) to implement a physics practicum after the COVID-19 Pandemic. This system is guided by exploratory inquiry questions to help structure students' mindsets in answering investigative questions. Online practicum is also integrated with video conferencing, chat,…

The purpose of this study is to illustrate the use of functional data analysis (FDA) as a general methodology for analyzing person response functions (PRFs). Applications of FDA to psychometrics have included the estimation of item response functions and latent distributions, as well as differential item functioning. Although FDA has been…

The past century has seen a debate on what characterises a scientifically literate citizen. Originally, scientific literacy implied that a citizen should know the products of science but has grown to incorporate processes of science and aspects of the nature of science. Studies on students' epistemic knowledge are rarer than ones on students'…

Feedback best practices support timely, high-quality feedback with application opportunity. Multiple attempts on assessments support learning gains. A learning management system can be used to automatically provide feedback for application on a future assessment attempt. Current research has not thoroughly investigated the student impacts or…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In this paper, we describe the results of a research project whose goals were to (1) develop and implement video-based experimental investigations using the Investigative Science Learning Environment (ISLE) approach and (2) study how…

In spring 2020, the chemical education community faced an abrupt transition from in-person to online classes, which also necessitated online assessments. Building upon an existing three-semester study (F17, S19, and F19) using Rasch modeling and classical testing theory to improve in-person multiple choice exams, this study investigates the impact…

Over the past few decades, physics education researchers (PER) developed a variety of assessments instrument for research and instructional purposes. Most of these instruments are designed to measure topical understanding. Generally, if student performance is satisfactory, it is assumed that the students possess the content understanding and that…

This study investigates the relationship between study methods and exam performance in introductory physics courses. Data were collected over 3 years through surveys to examine students' study habits, perceived effectiveness of techniques, and the correlation between time allocation and exam grades. Results indicate that high-achieving students…

Assessment developers are increasingly using the developing technology of machine learning in transforming how to assess students in their science learning. I argue that these algorithmic models further embed the structures of inequality that are pervasive in the development of science assessments in how they legitimize certain language practices…
