The study investigated the effects of a combination of Peer Discussion and Isomorphic Problems (PD-IPs) on high school students' graph understanding and conceptual learning. The study was conducted on kinematics and Newton's Laws of Motion with 67 high school students from two groups. The experimental group (EG) consisted of 34 students, while the…

In this study, we investigated female and male students' sense of belonging and their academic performance measured by the Force Concept Inventory (FCI) and course grades in a calculus-based introductory physics course at a large public university in the United States. We find that compared to male students, female students' sense of belonging was…

The landscape of undergraduate biology education has been shaped by decades of reform efforts calling for instruction to integrate core concepts and scientific skills as a means of helping students become proficient in the discipline. Assessments can be used to make inferences about how these reform efforts have translated into changes in…

Previous studies have shown the important role of different representations in the teaching and learning of physics. In this study, we used eye tracking to investigate the effect of different representations on the process of answering conceptual questions. We compared students' scores and eye-tracking measures on isomorphic questions which…

The traditional description of "the scientific method" as a stepwise, linear process of hypothesis testing through experimentation is a myth. Although the teaching and learning of the scientific method have been a curriculum and assessment goal, the notion of the 'scientific method' itself has been identified as being problematic. Many…

This paper presents improvements made to a computerized adaptive testing (CAT)-based version of the FCI (FCI-CAT) in regards to test security and test efficiency. First, we will discuss measures to enhance test security by controlling for item overexposure, decreasing the risk that respondents may (i) memorize the content of a pretest for use on…

We investigate students' misconceptions in electrostatics, direct current (DC) and magnetism which are important in electricity and magnetism. We developed and administered a multiple-choice questionnaire test to reveal students' misconceptions related to charged bodies, lightning, electric fields, electric potential, forces, DC resistive electric…

Many students experience a language-related barrier which may keep them from fully understanding and engaging in complex chemistry content. Although dense and technically rich scientific language is challenging for most students to interpret, it can become a systematic barrier for English Language Learner (ELL) students when it cognitively…

The purpose of this paper is to compare chemistry test performances between learners studying in resourced and under sourced schools. This has made many South Africans sensitive towards getting a better education for the upcoming generation. Common perception amongst the community is that private schools provide a better education due to their use…

The study investigated student reaction to the alternative mechanics survey (AMS), a modified force concept inventory, which used automatically marked free-response questions and offered limited feedback to students after their answers had been submitted. Eight participants were observed in completing the AMS, and they were interviewed to gain…

The aim of this study is to analyse the science questions in terms of visual content in the higher education entrance exams in Turkey. In this context, 1714 questions in total prepared by the Center for Measurement, Selection and Placement (CMSP) between 1999 and 2019 in the fields of Physics (n=631), Chemistry (n=553) and Biology (n=530)…

We investigated the effect of retrieval practice (i.e., the use of testing to enhance learning) by middle school students on science learning in an authentic educational setting. For initial study, all students (n = 39) read a science text and made study notes about the text, a regular study activity in their course. For restudy (2 days later),…

Items that are chained, or blocked, together appear on many of the conceptual assessments utilized for physics education research. However, when items are chained together there is the potential to introduce local dependence between those items, which would violate the assumption of item independence required by classical test theory,…

For assessment contexts where both a paper-based test and an on-screen assessment are available as alternatives, it is still common for the paper-based test to be prepared first with questions later transferred into an on-screen testing platform. One challenge with this is that some questions cannot be transferred. One solution might be for…

The purpose of this communication is to describe and document the challenges of delivering a general chemistry laboratory experience to students and of moving toward multiple small assessments and away from high-stakes examinations. By leveraging of activities that were already in place prior to the pivot to online learning, namely, an electronic…
