We explored analogies used for introducing students to the concept of potential energy wells. Two analogy systems were developed, a spring system and a novel system consisting of electrostatic spheres. These two, distinct analogies were housed within an interactive tool that allowed students to manipulate the analogous systems and witness changes…

After-school settings provide youth with homework support, social outlets and fun activities, and help build self-confidence. They are safe places for forming relationships with caring adults. More after-school settings are starting to integrate Science, Technology, Engineering, and Mathematics (STEM) topics. What science skills and concepts might…

In this paper, the researcher focuses on assessing the language learning benefits for students of adapting the communicative language teaching (CLT) methodology to an English textbook, a methodology that, according to Richards (2006), Littlewood (2008) and others, is influential in shaping second language learning worldwide. This paper is intended…

A lack of college readiness can affect student success in the classroom and impact retention rates. It has been recommended that all students be placed in courses with college-level content but that added support be provided for students identified as underprepared. This study examines the impact of added instructional time and support embedded…

Pollinating animals are profoundly affected by the current loss of biodiversity, a problem that is of concern to science, policy-makers and the public. One possibility to raise awareness for pollinator conservation is education. Unfortunately, insects such as bees are often perceived as frightening creatures; a negative emotion that may hinder…

The paper describes a biology tutoring system with adaptive question selection. Questions were selected for presentation to the student based on their utilities, which were estimated from the chance that the student's competence would increase if the questions were asked. Competence was represented by the probability of mastery of a set of biology…

This study investigates the effect of using the history of science in teaching geometrical optics on the motivation and conceptual understanding of first year university students. For this purpose, 54 students were randomly selected, then divided into two groups: the experimental group was taught by using history of science before traditional…

This study uses the feature sets employed by two automated scoring engines to determine if a "linguistic profile" could be formulated that would help identify items that are likely to exhibit differential item functioning (DIF) based on linguistic features. Sixteen items were administered to 1200 students where demographic information…

This paper presents the results of a study which examined the role of particular tasks implemented through two instructional methods on college students' achievement in probability. A mixed methods design that utilized a pre-test (with multiple-choice items) and post-test (with multiple-choice and open-ended items) in treatment and control groups…

This article describes a research study that determined the depth of vocabulary knowledge of 28 intermediate ESL learners. The study was carried out with Bricklayer, a vocabulary assessment tool for L2 English which tested the ESL learners on 72 words. Two post-tests collected evidence for concurrent validity. A semantic distance test captured…

Pragmatic competence is among the explicitly acknowledged sub-competences that make the communicative competence in any language (Bachman & Palmer, 1996; Council of Europe, 2001). Within the notion of pragmatic competence itself, "implicature (implied meanings)" comes to the fore as one of the five main areas there (Levinson, 1983).…

This study investigated the continuous influence of applying formative assessment on EFL (English as a foreign language) learners' anxiety and listening efficacy. The participants, divided into an experimental and a control group, were 60 Iranian EFL learners in an English-language institute. This study thus highlights the pedagogical implications…

The National Assessment of Educational Progress (NAEP) is the only continuing and nationally representative measure of trends in academic achievement of U.S. elementary and secondary school students in various subjects. For more than four decades, NAEP assessments have been conducted periodically in reading, mathematics, science, writing, U.S.…

Item analysis can serve as a useful tool in improving multiple-choice questions used in Extension programming. It can identify gaps between instruction and assessment. An item analysis of Mississippi Master Cattle Producer program multiple-choice examination responses was performed to determine the difficulty of individual examinations, assess the…

This study aimed at investigating the impact changing of escape alternative position in multiple-choice test on the psychometric properties of a test and it's items parameters (difficulty, discrimination & guessing), and estimation of examinee ability. To achieve the study objectives, a 4-alternative multiple choice type achievement test…
