Successful exam composition can be a difficult task. Exams should not only assess student comprehension, but be learning tools in and of themselves. In a biotechnology course delivered to nonmajors at a business college, objective multiple-choice test questions often require students to choose the exception or "not true" choice. Anecdotal student…

After a sudden increase in most of the individual grades in a multiple-choice test, students were asked to rank the three most relevant factors responsible for this outcome. Among eight others, the availability of a test for self-assessment before the final test was by far the most frequently mentioned (82.4% of the students). Questions applied…

This paper presents a problem-solving test that deals with the regulation of the "trp" operon of "Escherichia coli." Two mutants of this operon are described: in mutant A, the operator region of the operon carries a point mutation so that it is unable to carry out its function; mutant B expresses a "trp" repressor protein unable to bind…

In this study, differential item functioning (DIF) methods utilizing 14 different matching variables were applied to assess DIF in the constructed-response (CR) items from 6 forms of 3 mixed-format tests. Results suggested that the methods might produce distinct patterns of DIF results for different tests and testing programs, in that the DIF…

To investigate the effects of semantic mapping, thematic clustering, and notebook keeping on L2 vocabulary recognition and production, four groups of intermediate level learners in an EFL institute in Zanjan, Iran participated in the study. Three experimental groups consisted of semantic mapping, semantic feature analysis, and vocabulary notebook…

A stand-alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The…

Biological energy flow has been notoriously difficult to teach. Our approach to this topic relies on abiotic and biotic examples of the energy released by moving electrons in thermodynamically spontaneous reactions. A series of analogical model-building experiences was supported with common language and representations including manipulatives.…

Authentic language learning materials become prevalent in foreign and second language (L2) classrooms. Since these materials are not altered to suit the proficiency level or needs of L2 learners, they are likely to cause difficulties in comprehension. The purpose of this research was to examine the effect of advance organizers in conjunction with…

As an initial step toward understanding which features of academic language make science-based expository text difficult for students with different English language proficiency (ELP) designations, this study investigated fifth-grade students' thoughts on text difficulty, their knowledge of the features of academic language, and the…

The developmental sequence of mathematics courses in most 2-year and 4-year colleges is designed to prepare students to succeed in college-level math courses. That is, students must complete this sequence in order to progress to courses such as statistics, college algebra, precalculus, calculus, and differential equations. Research on the…

The purpose of this study was to examine the effects of a question-exploration routine and an associated graphic organizer on students' ability to think about and answer complex questions. Participants were 116 students of diverse abilities in seven 7th grade classes. The effects of the routine were compared with the effects of a traditional…

The perceived relation between assigned student grades and instructor evaluations of teaching has been the subject of much debate, though few laboratory studies have been conducted with adequate controls. Marsh and Roche suggested that experimental field studies may be a particularly promising avenue for further analyses of this relation. The…

Cultural integration can be used as an effective learning practice in contexts of English as Foreign Language (EFL) classrooms. The present study aimed at investigating the effect of cultural integration on the development of Iranian EFL upper-intermediate learners' listening comprehension. To this end, fifty-two upper-intermediate EFL learners…

With 73 students at an Iranian university, the present study investigated teacher's effect in topic familiarization in L2 reading context. The participants--Group B with and Group A without the presence of a teacher--experienced four pre-reading treatments and read four passages of unfamiliar topics, after which they were tested on comprehension…

The massification of higher education (HE) has led to an unprecedented increase in the number of students in the classrooms, resulting in increased workload for teaching staff, sometimes leading to a great reliance on Multiple Choice Questions (MCQs) examinations with limited feedback provided to students. The central role of feedback in student…
