Estimating the Effect on Grades of Using Multiple-Choice Versus Constructive-Response Questions: Data From the Classroom

This study investigates the degree to which grades based solely on constructed-response (CR) questions differ from grades based solely on multiple-choice (MC) questions. If CR questions are to justify their higher costs, they should produce different grade outcomes than MC questions. We use a data set composed of thousands of observations on individual students in introductory economics classes at a large public university. We note that the instructors of these classes made conscientious efforts to write CR questions that assessed higher levels of learning (Bloom, 1956 Bloom, B. S. 1956. Taxonomy of educational objectives: The classification of educational goals, handbook 1: Cognitive domain. New York: McKay..  [Google Scholar]). Despite this, we find relatively little difference in grade outcomes. Our analysis suggests that switching from an all-CR assessment to an all-MC assessment would produce grade variations that are similar to the differences that are observed for students across different tests. Although other studies have focused on test scores, frequently AP test scores, our study is the first to focus attention on university grades. We hope that our inability to identify substantial benefits to CR questions in terms of grades will stimulate further research to identify substantive benefits from using the more costly CR questions.     

COMMUNITY COLLEGE TENURE: TEACH OR RESEARCH?

How responsible community colleges can help determine the degree to which they are serving the educational needs of minorities is the focus of this paper. The authors illustrate the importance of using US Census data and enrollment characteristics to assess how well colleges are serving the needs of all their constituencies. An example of how these data have been used for community colleges in one state is presented. The methodology discussed is seen as effective, however, only when such an assessment is used as the foundation upon which a complete package of services is provided to meet the needs of all students     

Retell as an Indicator of Reading Comprehension

The purpose of this narrative synthesis is to determine the reliability and validity of retell protocols for assessing reading comprehension of students in grades K–12. Fifty-four studies were systematically coded for data related to the administration protocol, scoring procedures, and technical adequacy of the retell component. Retell was moderately correlated with standardized measures of reading comprehension and, with older students, had a lower correlation with decoding and fluency. Literal information was retold more frequently than inferential, and students with learning disabilities or reading difficulties needed more supports to demonstrate adequate recall. Great variability was shown in the prompting procedures, but scoring methods were more consistent across studies. The influences of genre, background knowledge, and organizational features were often specific to particular content, texts, or students. Overall, retell has not yet demonstrated adequacy as a progress monitoring instrument.     

From description to depiction: free indirect discourse and online graphical chat

Iconographic avatars in web-based graphical chat environments work to create a ‘shattered’ sense of self through the use of emblematics (the bringing together of text and image) coupled with a reformulated use of free indirect discourse, a style of indirect address found in the modern bourgeois novel. Free indirect discourse, or ‘middle voice’, is crafted by the novelist but takes on the characteristics of the person described, even as the difference between novelist and character creates an ironic distance directed at both the character and the reader who may be encouraged by the style to identify with the character. Avatar-driven graphical chat suggests a synthesis of the value of an avatar external to oneself and that of the ironic distance provided by free indirect discourse. The ‘middle ground’ of iconographic graphical chat environments exemplifies how images reformulate and seemingly mitigate the tensions inherent in text-based free indirect discourse – with its suggestion of ‘experience without a subject’ – to create greater ambiguity, irony and abstraction of the self and others. This mirrors how various forces of global capital work to reformulate the subject.     

Potentiation of responding on a VR schedule by a stimulus correlated with reinforcement: Effects of diffuse and localized signals

In Experiment 1, rats were trained to leverpress on a variable ratio (VR) 30 schedule with a 500-msec delay between the reinforced response and food delivery. Subjects that experienced a signal during the delay responded faster than did control subjects that received the stimulus un-correlated with reinforcement. Higher response rates were obtained when the stimulus used to signal reinforcement was auditory rather than visual. Experiments 2 and 3 compared the effects of signaling reinforcement with either a localized or a diffuse light on responding maintained by VR schedules of reinforcement. Elevated response rates were observed with the diffuse stimulus, but the localized stimulus failed to produce such potentiation. Experiment 3 also examined the conditioned reinforcing power of localized and diffuse visual stimuli. These results are discussed with reference to (1) theories of selective association and sign tracking and (2) their implications for current theories of signaling reinforcement.     

Differences in science students' view of ideal and actual role behavior according to success and gender

Information about how success and gender affect students' views of ideal and actual classroom role behavior can help both researchers and teachers better understand classroom components such as achievement and curriculum. A 20-item double Q sort was used to measure differences in perceptions of high school science students according to letter grades and gender. Individual Q sort item rankings of 160 students were tested for significant differences according to letter grade received; item ratings were compared according to gender for 215 students. Differences in perception according to success were found for both ideal and actual behavior; 8 and 5 items, respectively, out of each 20-item sort were found to be significant at the p = < 0.05 level. No such overall patterns of difference in view were found between boys and girls, although three ideal student items and one actual self-report item were found to be significantly different at the p = < 0.05 level.     

The education welfare service: the case for a review in England

The only major review of the education welfare service (EWS) took place in 1973 when the role and responsibilities of the service were very different from those of today. Recent legislative changes, the influence of the Children Act 2004 and revised public needs of the service, including new multidisciplinary and interdisciplinary frameworks, suggest that an up‐to‐date review would be timely. It may also help to professionalise the service in a number of different ways, something which is long overdue. This paper provides both the rationale and evidence for making the case for a major review of the EWS based on a reading of all key relevant documents and participation in a range of local and national evaluations on the role of the EWS in England and Wales. The major issues which need to be reviewed are identified and a way forward is suggested.
