Using Task Clarification,Checklists and Performance Feedback to Improve the Appearance of a Grocery Store

An intervention package of task clarification, checklists, and posted performance feedback was developed to increase completion of tasks contributing to the appearance of a local grocery store. The intervention package was based on an informal diagnostic assessment that examined antecedents, equipment and processes, knowledge and skills, and consequences in the organizational environment. A multiple baseline design across five departments was utilized to evaluate the effects of the intervention package on employee cleaning behavior related to the appearance of the store. The results suggest overall improvement of task completion across the five departments observed, with substantial increases resulting from application of the intervention. The mean percentage of tasks completed in the deli department increased by 36%; by 93% in the meat department; by 38% in the frozen department; by 25% in the produce department; and by 34% in the front‐end department. The average increase of task completion across departments was more than 45%. The results of this study are consistent with those of Anderson, Crowell, Hantula, and Siroky (1988), as well as with La Fleur and Hyten (1995), demonstrating that task clarification, checklists, and feedback have positive effects on work performance.     

An analysis of question asking on scientific texts explaining natural phenomena

This article relays results of a study focused on questions invoked to correct declarative knowledge deficits while readers process science texts explaining natural phenomena. Firstly, the authors focused on finding out what kind of questions are asked by students who read these texts and, secondly how task demand influences quantity and quality of formulated questions. Two hundred and eighty nine Portuguese students from 8th, 10th, and 12th grade participated in the study. The students were instructed to ask questions on two short science paragraphs that explained natural phenomena. Three task conditions were chosen. Thus, in the “Class” condition, the task was introduced as an activity aimed at developing the capacity to ask questions. In the “Examination” condition, the task was presented as a test on question generation. Finally, in the “Extra‐academic” condition the questioning task was camouflaged as a participation in a research project sponsored by the Ministry of Education and geared at the improvement of science textbooks. The results have shown that students are able to ask many questions when given an opportunity to do so. The study has also proven that students are capable of generating a large volume of causal‐antecedent questions relative to this kind of texts. Finally, no clear effects were found between grade level and/or task demand as defined in the conducted study. © 2000 John Wiley & Sons, Inc. J Res Sci Teach 37: 602–614, 2000     

Collaborative processes during report writing of a science learning project: The nature of discourse as a function of task requirements

The aim of this article is to specify how different aspects of task assignments are related to different types of student discourse during the report writing phase of a science learning project. A group of four ninth-grade students of the Finnish comprehensive school (about 15-year-olds) participated in a project work involving laboratory experiments, reading literature, and analysing and reporting research findings. The empirical data were collected through videotaping and interviews in authentic classroom settings. The results indicated that construction of shared, high-level understanding was quite rare in this case of small group interaction. As one of the main reasons for this, we suggest that the learning tasks were defined in a way that did not encourage shared reflection and high-level discourse. The students’ task was mostly to answer fact-seeking questions made by their teacher to guide the report writing, which promoted recollection rather than reasoning. In order to facilitate high-level discourse and learning, more attention should be paid to the kind of processes that task assignment triggers. The findings are discussed in the framework of how teachers could formulate their task assignments to promote high-level discourse.     

Repeated high-intensity exercise in professional rugby union

The aim of the present study was to describe the frequency, duration, and nature of repeated high-intensity exercise in Super 14 rugby union. Time-motion analysis was used during seven competition matches over the 2008 and 2009 Super 14 seasons; five players from each of four positional groups (front row forwards, back row forwards, inside backs, and outside backs) were assessed (20 players in total). A repeated high-intensity exercise bout was considered to involve three or more sprints, and/or tackles and/or scrum/ruck/maul activities within 21 s during the same passage of play. The range of repeated high-intensity exercise bouts for each group in a match was as follows: 11-18 for front row forwards, 11-21 for back row forwards, 13-18 for inside backs, and 2-11 for outside backs. The durations of the most intense repeated high-intensity exercise bouts for each position ranged from 53 s to 165 s and the minimum recovery periods between repeated high-intensity exercise bouts ranged from 25 s for the back row forwards to 64 s for the front row forwards. The present results show that repeated high-intensity exercise bouts vary in duration and activities relative to position but all players in a game will average at least 10 changes in activity in the most demanding bouts and complete at least one tackle and two sprints. The most intense periods of activity are likely to last as long as 120 s and as little as 25 s recovery may separate consecutive repeated high-intensity exercise bouts. The present findings can be used by coaches to prepare their players for the most demanding passages of play likely to be experienced in elite rugby union.     

Associations Among Teacher–Child Interactions,Teacher Curriculum Emphases,and Reading Skills in Grade 1

Research Findings: The purpose of the present study was to examine the extent to which the quality of teacher–child interactions and teachers’ self-reported curriculum emphases are related to children’s reading skill development during their 1st school year. To accomplish this, we assessed the reading skills of 1,029 Finnish children (M age = 85.77 months) twice during Grade 1, and the children’s teachers (n = 91) completed questionnaires concerning their literacy-related curriculum emphases. In addition, teacher–child interactions in terms of emotional support, classroom organization, and instructional support were observed in 29 classrooms. The results of multilevel modeling showed that a high global quality of teacher–child interactions was positively associated with improved children’s reading skills at the end of Grade 1. In addition, a teacher emphasis on comprehension and production skills was related to better reading skills via teacher–child interactions. Domain-specific analyses revealed that emotional support and classroom organization in particular were related to better reading skills. Practice or Policy: The present study adds to previous research by showing that children had better reading skills at the end of their 1st school year in classrooms in which the teachers were warm, responsive, and sensitive to children’s needs and provided well-planned activities, clear rules, and expectations for behavior.
