Error correction in text

Previous research has shown that writers and editors of all ages and abilities have trouble correcting errors in texts. In this study, we were interested in discovering whether people do not correct these errors mainly because (1) they do not have the knowledge to correct them, or because (2) even though they do have the knowledge to correct the errors, they do not use it. The first case would point to aknowledge deficit, or a deficit at the cognitive level; the second case would point to aprocessing deficit, or a deficit at the metacognitive level. The study compared the number and type of implanted errors corrected by high school and college subjects working on two different texts under three different conditions. We found that, for both ages, the biggest stumbling block in correcting errors was not the knowledge of how to correct them, but rather a failure to detect them: They did not use their available knowledge to find the errors. This processing deficit may be the result of a dearth of available error-finding strategies, or knowledge may not be activated because of lack of motivation or because of a failure to perceive the nature of the task.     

Design implications from a usability study of GramStain-TutorTM

To examine interface issues in an educational software program, we recruited twenty-two users in health sciences departments for a usability study. Using the GramStain-Tutor™ (GST) CD-ROM, these users performed tasks in navigating the program and using various interactive features. Their actions and comments were recorded with a digital video recorder and an audio recorder. The main results of our study are: (a) the majority of the users did not use the multiple navigational options available in the program; (b) navigational patterns differed based on the training background and content knowledge of the users; (c) several visual cues critical to program use were not discovered by the majority of the users; and (d) icons representing specific functions were not intuitive from users' perspectives. We demonstrated how a usability study of a relatively small number of users can identify specific problems in interface design. We recommend these interface problems be addressed before conducting educational studies that examine how educational software programs affect student learning.     

Community Education and child-care programs

The Community Education Services (CES) division of the Children's Television Workshop (CTW) is CTW's community-outreach arm. This article describes how CES works with parents, children, experts, and local groups to develop special multimedia products, four of which are discussed. Two of the products—a fire-safety kit and a natural-hazards packet—were designed to teach young children how to protect themselves in life-threatening emergencies. Two other products—CES'sSesame Street preschool education materials and its3-2-1 Contact andSquare One TV after-school materials—are attempts by CTW to respond to societal changes that have increasingly shifted the burden of child care onto preschool and after-school programs.     

Text Comprehension and Oral Language as Predictors of Word-Problem Solving: Insights into Word-Problem Solving as a Form of Text Comprehension

This study was designed to deepen insights on whether word-problem (WP) solving is a form of text comprehension (TC) and on the role of language in WPs. A sample of 325 second graders, representing high, average, and low reading and math performance, was assessed on (a) start-of-year TC, WP skill, language, nonlinguistic reasoning, working memory, and foundational skill (word identification, arithmetic) and (b) year-end WP solving, WP-language processing (understanding WP statements, without calculation demands), and calculations. Multivariate, multilevel path analysis, accounting for classroom and school effects, indicated that TC was a significant and comparably strong predictor of all outcomes. Start-of-year language was a significantly stronger predictor of both year-end WP outcomes than of calculations, whereas start-of-year arithmetic was a significantly stronger predictor of calculations than of either WP measure. Implications are discussed in terms of WP solving as a form of TC and a theoretically coordinated approach, focused on language, for addressing TC and WP-solving instruction.     

Development of turn and turn measurement concepts in a computer-based instructional unit

This study investigated the development of turn and turn measurement concepts within a computer-based instructional unit. We collected data within two contexts, a pilot test of this unit with four third graders and a field test in two third grade classrooms. We conducted paper-and-pencil assessments, interviews, and interpretive case studies. Turns were less salient for children than forward and back motions. Students evinced a progressive construction of imagery and concepts related to turns. They gained experience with physical rotations, especially rotations of their own bodies. In parallel, they gained limited knowledge of assigning numbers to certain turns, initially by establishing benchmarks. A synthesis of these two domains — turn-as-body-motion and turn-as-numbe — constituted a critical juncture in learning about turns for some students. Some common misconceptions, such as conceptualizing angle measure as a linear distance between two rays, were not in evidence. This supports the efficacy and usefulness of instructional activities such as those employed.     

Virtual(ly) Athletes: Where eSports Fit Within the Definition of “Sport”

Electronic sports, cybersports, gaming, competitive computer gaming, and virtual sports are all synonyms for the term eSports. Regardless of the term used, eSports is now becoming more accepted as a sport and gamers are being identified as athletes within society today. eSports has even infiltrated higher education in the form of an intercollegiate athletic sport, as two university athletic departments have made eSports an official varsity sport where scholarships are provided to collegiate eSports athletes. Thus, the intertwining of eSports and university athletics brings into question whether eSports should be considered sport by broader society. This article provides a brief history of eSports, a further developed definition of eSports, and a comparison of eSports to traditional philosophical and sociological definitions of sport. The purpose of this article is to provoke thought on the academically accepted definitions of sport and debate whether eSports should be considered a sport. Attention will be given to the following components of sport: play, organization, competition, skill, physicality, broad following, and institutionalization.     

Student loans and their alternatives: improving the performance of deferred payment programs

The opportunities for increasing student contributions to the costs of higher education are many. Student loans have received much attention both in literature and in practice. While they have not always worked well, we have argued that suitably reformed, they can constitute a productive, though limited, mechanism for cost recovery. In certain countries, however, other mechanisms may be more appropriate. Indeed, the policy maker is presented with a wide menu of policy choices, though some creativity may be required in their application to particular local settings. Currently, loan programs exist in over 50 developing and industrial countries, and have been introduced most commonly to assist students to pay their living expenses.In order to improve financial effectiveness, programs should be targeted toward the most needy and able students. Hidden subsidies should be limited by charging positive real interest rates, combined with repayment plans that take account of the likely pattern of graduate earnings. Default reductions require that loan programs be managed by institutions with the capacity and financial incentives to collect - namely banks, private collection agencies, or taxation departments. Such reforms offer great potential to transform small programs into relatively efficient forms of student support.Larger programs, however, may be more difficult to manage. Some countries have considered alternatives which preserve the basic concept of paying for education from future income. The most notable is a graduate tax in which a student pays a fixed percentage of income over the entire working life, regardless of how much is repaid. Another option is national service which require students to perform socially productive work in exchange for part or all of education costs. In the presence of an effective tax system, a graduate tax could bring in significantly more revenue than traditional loan programs. Besides improved financial efficiency, income contingent payments may be more equitable since they limit the risk to poorer students. In countries with weak taxation systems, this option may not be feasible.     

Children's Perception of Pictorial Metaphor

Abstract Pictures for children commonly contain pictorial metaphor. This non‐mimetic information supplements, clarifies or renders unambiguous properties or actions represented in the mimetic parts of a picture. Children's perception of some pictorial metaphors may not be wholly by processing them as metaphors or implied analogies but as word‐like figures. Some evidence is presented which may support this view.
