In the context of introductory physics, we study student conceptual understanding of differentials, differential products, and integrals and possible pathways to understanding these quantities. We developed a multiple choice conceptual assessment employing a variety of physical contexts probing physical understanding of these three quantities and…

Item analysis of Multiple Choice Questions (MCQs) is the process of collecting, summarizing and utilizing information from students' responses to evaluate the quality of test items. Difficulty Index (p-value), Discrimination Index (DI) and Distractor Efficiency (DE) are the parameters which help to evaluate the quality of MCQs used in an…

Developing a better understanding of the measurement process and measurement uncertainty is one of the main goals of university physics laboratory courses. This study investigated the influence of graphical representation of data on student understanding and interpreting of measurement results. A sample of 101 undergraduate students (48 first year…

We propose a new course structure to address the needs of college students with previous calculus study but no course validations as an alternative to repeating the first year of calculus. Students are introduced directly to topics from Calculus III unpreceded by a formal review of topics from Calculus I or II, but with additional syllabus time…

Multiple choice writing guidelines are decidedly split on the use of "none of the above" (NOTA), with some authors discouraging and others advocating its use. Moreover, empirical studies of NOTA have produced mixed results. Generally, these studies have utilized NOTA as either the correct response or a distractor and assessed its effect…

The purpose of this study was to explore the effect of problem-based learning (PBL) on student achievement and students' perceptions of classroom quality. A group of students taught using PBL and a comparison group of students taught using traditional instruction were studied. A total of 457 students participated in the study. Pre- and…

We developed and validated the Conceptual Assessment of Natural Selection (CANS), a multiple-choice test designed to assess how well college students understand the central principles of natural selection. The expert panel that reviewed the CANS concluded its questions were relevant to natural selection and generally did a good job sampling the…

The purpose of this study is to prepare a multiple-choice achievement test with high reliability and validity for the "Let's Solve the Puzzle of Our Body" unit. For this purpose, a multiple choice achievement test consisting of 46 items was applied to 178 fifth grade students in total. As a result of the test and material analysis…

This study examines the extent to which 70 Kuwaiti EFL learners are aware of the formation rules of tag questions in English. It also investigates whether the English proficiency level of the participants contributes to their correct answers on the test. For this purpose, the researchers used a multiple-choice test to measure the participants'…

An active learning activity was used to engage students and enhance in-class learning of cell cycle regulation in a PharmD level integrated biological sciences course. The aim of the present study was to determine the effectiveness and perception of the in-class activity. After completion of a lecture on the topic of cell cycle regulation,…

This study investigates how factors such as student achievement goals for a course, language skills, outside work commitments, and test anxiety are related to performance on multiple-choice exams and nonexam assignments. The study also explores whether these factors explain the time taken to complete exams and whether exam completion speed is…

Existing research concludes that educators have varying levels of language knowledge. Educators' varying levels of language knowledge may be related to the type of content knowledge they received while in school. The purpose of this study was to compare the performance of pre-professional speech-language pathology (SLP) students who have taken…

This study investigates the impact that study in Australia has on the lexical knowledge of Saudi Arabian students. It focuses on: 1) the effects that the length of study in Australia has on the acquisition of lexical collocations, as reflected by lexical knowledge tests, and 2) whether there is a significant gender difference in the acquisition of…

Geoscience education researchers have considerable need for criterion-referenced, easy-to-administer, easy-to-score, conceptual surveys for undergraduates taking introductory science survey courses in order for faculty to monitor the learning impacts of innovative teaching. In response, this study establishes the reliability and validity of a…

Physical and virtual experimentation are thought to have different affordances for supporting students' learning. Research investigating the use of physical and virtual experiments to support students' learning has identified a variety of, sometimes conflicting, outcomes. Unanswered questions remain about how physical and virtual experiments may…
