How to Analyze Interpersonal and Individual Effects in Peer-Tutored Reading Intervention

Reading strategy interventions relying upon peer tutoring are a common way to foster poor readers' comprehension skills. Those interventions are based on the assumption that tutees benefit from the (higher) reading skills of their tutors. However, this interpersonal effect has not yet been tested explicitly because the effectiveness of peer tutoring is commonly analyzed separately for tutees and tutors or with aggregated data. The present study illustrates how interpersonal and individual effects of a peer-tutored reading strategy intervention can be estimated using dyads as units of analysis in structural equation modeling. To demonstrate the application of the model, data from an experimental intervention study comparing the effects of a peer-tutored reading strategy training and a control condition in Grade 4 (N = 68 dyads) were analyzed.     

Does learning in clinical context in anatomical sciences improve examination results,learning motivation,or learning orientation?

The preclinical compulsory elective course “Ready for the Operating Room (OR)!?” [in German]: “Fit für den OP (FOP)”] was implemented for students in their second year, who were simultaneously enrolled in the gross anatomy course. The objective of the study was to determine whether the direct practical application of anatomical knowledge within the surgical context of the course led to any improvement in learning motivation, learning orientation, and ultimately examination results in the gross anatomy course, as compared with a control group. Within the scope of five teaching sessions, the students learned surgical hand disinfection, suturing techniques, and the identification of commonly used surgical instruments. In addition, the students attended five surgical demonstrations performed by surgical colleagues on cadavers. Successful learning of these basic skills was then assessed based on an Objectively Structured Practical Examination. Learning motivation and learning orientation in both subgroups was determined using the SELLMO‐ST motivation test and the Approaches and Study Skills Inventory test. While a significant increase in work avoidance was identified in the control group, this was not the case for FOP participants. Similarly, an increase in the “deep approach” to learning, as well as a decrease in the “surface approach,” was able to be documented among the FOP participants following completion of the course. The results suggest that students enrolled in the gross anatomy course, who were simultaneously provided with the opportunity to learn in clinical context, were more likely to be successful at maintaining learning motivation and learning orientation required for the learning process, than students who attended the gross anatomy course alone.

Behavioral objectives,sequence, and anxiety in CAI

A total of 117 subjects were randomly assigned to a group receiving instructional objectives, or not doing so, and to a logical or random instructional sequence. Performance measures, as well as test and state anxiety scores were obtained. Regression analysis indicated that, as expected, objectives had no effect, whereas the logical sequence reduced program errors and increased achievement. Test anxiety was related to program errors, but not to achievement. Expected interactions among objectives, sequence, and anxiety were not significant.A prior version of this paper was read at the American Educational Research Association annual convention in New Orleans, La., March 1973.This study was completed while the senior author was on leave at the CAI Center, Florida State University. The present paper was completed at the City University of New York.     

The ability to estimate knowledge and performance in college: A metacognitive analysis

While in college students learn a great deal of new knowledge, and over time successful students learn to update their knowledge as new concepts, facts, and procedures are acquired. The metacognitive ability to accurately estimate one's knowledge was hypothesized to be related to academic achievement in college. The two studies reported in this paper examined the relationship between a measure of metacognitive word knowledge (the KMA) and performance in college. Using undergraduate gpa in a number of academic domains as criterion measures, this research provides support for the validity of the KMA as a predictor of success in college. Suggestions for further research relating performance on the KMA to learning in complex domains are offered.     

Specificity aboutness in XML retrieval

This paper presents a theoretical methodology to evaluate XML retrieval systems and their filters. Theoretical evaluation is concerned with the formal investigation of qualitative properties of retrieval models. XML retrieval deals with retrieving those document components that specifically answer a query, and filters are a method of delivering the most focussed answers. Our theoretical evaluation critically analyzes how filters achieve this.

Cognitive load in percentage change problems: unitary,pictorial, and equation approaches to instruction

Eighth grade students in Australia (N = 60) participated in an experiment on learning how to solve percentage change problems in a regular classroom in three conditions: unitary, pictorial, and equation approaches. The procedure involved a pre-test, an acquisition phase, and a post-test. The main goal was to test the relative merits of the three approaches from a cognitive load perspective. Experimental results indicated superior performance of the equation approach over the unitary or pictorial approach especially for the complex tasks. The unitary approach required students not only to process the interaction between numerous elements within and across solution steps, but also to search for critical information, thus imposing high cognitive load. The pictorial approach did not provide a consistent approach to tackling various percentage change problems. Coupled with the need to coordinate multiple elements within and across solution steps, and the need to search for relevant information in the diagram, this approach imposed high cognitive load. By treating the prior knowledge of percentage quantity as a single unit, the equation approach required students to process two elements only. Empirical evidence and theoretical support favor the equation approach as an instructional method for learning how to solve percentage change problems for eighth graders.     

Retrieval-based learning in special education

Retrieval-based learning has been investigated in various populations. The present study examined retrieval-based learning in a sample of students at a special-needs school with educational tracks for learning and mental development. In addition, a comparison group of students at a regular school was examined. Learning conditions were manipulated within participants. In a first session, participants either received restudy cycles only, or they received alternating test and restudy cycles. A second session then comprised the opposite form of practice. In both sessions, a final test assessed memory after a short distractor phase. This procedure was the same in two experiments but with different kinds of item material. For both kinds (images and image-word pairs), a testing effect occurred, that is higher recall of tested items. These results show that lower cognitive ability or lack of experience with regularly being tested in school do not prevent students from benefiting from retrieval-based learning.
