Warning readers to avoid irrelevant information: When being vague might be valuable

Students are often provided with instructions that are intended to influence their attention to particular sections or elements of their reading materials. To date, the bulk of the work on such prereading instructions has focused on drawing reader attention to relevant text information. In the current project, we examined whether instructions might also be useful in helping readers ignore irrelevant (albeit inherently interesting) information in text. In two experiments, prereading instructions asked readers to (a) focus on specific relevant text segments, (b) ignore specific irrelevant text segments, (c) maintain an awareness that the text contained irrelevant segments without specifically identifying them, or (d) read without warnings. Participants generally exhibited longer reading times and enhanced recall for irrelevant segments compared to base content, except in cases for which general instructions warned about but did not specifically identify those irrelevant elements. The implications of these findings for research on seductive details and text processing, as well practical applications for the design of reading instruction, are discussed.     

Time-restricted feeding in young men performing resistance training: A randomized controlled trial†

A randomized controlled trial was conducted to examine eight weeks of resistance training (RT) with and without time-restricted feeding (TRF) in order to assess nutrient intake and changes in body composition and muscular strength in young recreationally active males. The TRF programme consisted of consuming all calories within a four-hour period of time for four days per week, but included no limitations on quantities or types of foods consumed. The RT programme was performed three days per week and consisted of alternating upper and lower body workouts. For each exercise, four sets leading to muscular failure between 8 and 12 repetitions were employed. Research visits were conducted at baseline, four, and eight weeks after study commencement. Measurements of total body composition by dual-energy X-ray absorptiometry and muscle cross-sectional area by ultrasound were obtained. Upper and lower body strength and endurance were assessed, and four-day dietary records were collected. TRF reduced energy intake by ～650?kcal per day of TRF, but did not affect total body composition within the duration of the study. Cross-sectional area of the biceps brachii and rectus femoris increased in both groups. Effect size data indicate a gain in lean soft tissue in the group that performed RT without TRF (+2.3?kg, d?=?0.25). Upper and lower body strength and lower body muscular endurance increased in both groups, but effect sizes demonstrate greater improvements in the TRF group. Overall, TRF reduced energy intake and did not adversely affect lean mass retention or muscular improvements with short-term RT in young males.     

A Study of Effective First-Grade Literacy Instruction

Literacy instruction in first-grade classrooms in five U.S. locales was observed. Based on academic engagement and classroom literacy performances, the most-effective-for-locale and least-effective-for-locale teachers were selected. The teaching of the most-effective-for-locale teachers was then analyzed, including in relation to the teaching of the least-effective-for-locale teachers. The classrooms headed by most-effective-for-locale teachers were characterized by excellent classroom management based on positive reinforcement and cooperation; balanced teaching of skills, literature, and writing; scaffolding and matching of task demands to student competence; encouragement of student self-regulation; and strong cross-curricular connections. In general, these outcomes did not support any theory that emphasizes just one particular component (e.g., skills instruction, whole language emphasis) as the key to effective Grade 1 literacy; rather, excellent Grade 1 instruction involves multiple instructional components articulated with one another.     

Action learning: the possibility of differing hierarchies in learning sets

This paper presents the proposition that a variety of differing hierarchies exist in an action learning set at any one time, and each hierarchy has the potential to affect an individual's behaviour within the set. An interpretivist philosophy underpins the research framework adopted in this paper. Data were captured by means of 11 in-depth interviews that formed part of wider research into set members' perceptions of what makes an effective action learning set. The interviewees were all former students of the researcher and her colleagues. The research draws upon grounded theory as a dominant research paradigm and uses thematic analysis to interpret the research findings. The findings of the research serve to simply illustrate that there is the potential for a variety of differing hierarchies to exist in an action learning set at any one time. Some of the hierarchies may exist for the full duration of the set; others are somewhat ephemeral. The findings from this research also present themselves as points of consideration for academics and practioners who have used or are about to use action learning as a learning vehicle.     

Project Clarion: Three Years of Science Instruction in Title I Schools among K-Third Grade Students

The purpose of the study was to measure the effects of higher level, inquiry-based science curricula on students at primary level in Title I schools. Approximately 3,300 K-3 students from six schools were assigned to experimental or control classes (N?=?115 total) on a random basis according to class. Experimental students were exposed to concept-based science curriculum that emphasized ??deep learning?? though concept mastery and investigation, whereas control classes learned science from traditional school-based curricula. Two ability measures, the Bracken Basic Concept Scale-Revised (BBCS-R, Bracken 1998) and the Naglieri Nonverbal Intelligence Test (NNAT, Naglieri 1991), were used for baseline information. Additionally, a standardized measure of student achievement in science (the MAT-8 science subtest), a standardized measure of critical thinking, and a measure for observing teachers?? classroom behaviors were used to assess learning outcomes. Results indicated that all ability groups of students benefited from the science inquiry-based approach to learning that emphasized science concepts, and that there was a positive achievement effect for low socio-economic young children who were exposed to such a curriculum.     

Comprehension of written sentences as a core component of children's reading comprehension

Two experiments were conducted to test the hypothesis that sentence processing is an essential mediatory skill between word recognition and text comprehension in reading. In Experiment 1, a semantic similarity judgement task was used with children from Grade 2 to Grade 9. They had to say whether two written sentences had the same (or very similar) meanings or whether the meanings of the two sentences were very different. As expected, performance improved with age both on the high‐frequency words and with increasingly complex sentences. In Experiment 2 with children in Grade 3, scores in written sentence comprehension and vocabulary made the most important unique contribution to the reading comprehension of an expository text. The results are discussed first, in the light of a general framework in which sentence‐level skill is at the core of reading comprehension and second, with reference to the issue of reading assessment.
