The history of mathematics is full of rich examples that can help students to see the place of the discipline within our cultural heritage. Valuable as this can be, it also has the unfortunate side-effect of making students think that all the math has already been done and they do not get a sense that the subject is dynamic and growing.…

This article offers an analysis of the process of error recovery as observed in the development and use of collections databases in a university museum. It presents results from a longitudinal case study of the development of collaborative systems and practices designed to reduce the number of errors found in the museum's databases as museum…

This paper presents comments on the article by D. Westen and J. Weinberger, which stated that '...science can be viewed as the history of confirmatory biases" (p. 609). This comment's authors prefer an alternative formulation: The history of science can be viewed as a constant and largely successful struggle to overcome confirmatory biases.…

The correction for attenuation due to measurement error (CAME) has received many historical criticisms, most of which can be traced to the limited ability to use CAME inferentially. Past attempts to determine confidence intervals for CAME are summarized and their limitations discussed. The author suggests that inference requires confidence sets…

Comments on the response offered by Cheng and Novick to White's initial comments on Cheng's and Cheng and Novick's previous articles. White asks if regularity information necessary for causal learning. He and Cheng and Novick agree that the causal relation is understood as a generative relation, but disagree on how this understanding comes about.…

Recasts have figured prominently in recent SLA research, with studies documenting significant advantages for learners exposed to this type of negative feedback. Although some researchers have suggested that such findings imply a beneficial role for negative evidence (i.e., information regarding the impossibility of certain utterances in the…

The debate continues between those who believe in giving corrective feedback to students to improve their written accuracy and those who do not. Indeed, the results of the many experimental studies on written corrective feedback carried out over the last 20 years have been so contradictory that second language teachers looking to support their…

Researchers of scholarly literacy are becoming more aware that a published research article, especially if it is written by an English as an Additional Language (EAL) author, needs to be viewed as a product involving a range of "shapers" who participate in the editorial process (e.g., Burrough-Boenisch, 2003). Drawing on data gathered…

There is significant potential for error in long production processes that consist of sequential stages, each of which is heavily dependent on the previous stage, such as the SER (Scoring, Equating, and Reporting) process. Quality control procedures are required in order to monitor this process and to reduce the number of mistakes to a minimum. In…

Articles in this issue of "Global Journal of Computer Science and Technology" include: (1) Input Data Processing Techniques in Intrusion Detection Systems--Short Review (Suhair H. Amer and John A. Hamilton, Jr.); (2) Semantic Annotation of Stock Photography for CBIR Using MPEG-7 standards (R. Balasubramani and V. Kannan); (3) An Experimental Study…

Secondary schools--be they middle schools or high schools--are reading-rich environments. Secondary schools provide contexts in which students must regularly read and write competently to demonstrate their literacy achievement. In any given semester, there are short stories and novels to read, comprehend, and analyze; civics and science texts…

In 1999 Stephen Gorard published an article in this journal in which he provided a trenchant critique of what he termed the "politician's error" in analyzing differences in educational attainment. The main consequence of this error, his argument, has been the production of misleading findings in relation to trends in educational performance over…

Extensive research has been conducted about feedback on writing in both L1 and L2 classrooms. Although much of the research suggests that correcting grammar does not help students make long-term improvements, many teachers continue to believe that they must correct all errors. In addition, students report that they want teachers to mark errors.…

The hypothesis is introduced that 1 source of shift costs is the strengthening of task-related associations occurring whenever an overt response is produced. The authors tested this account by examining shift effects following errors and error compensation processes. The authors predicted that following a specific type of error, called task…

The application range of Cohen's Kappa is extended to the field of sequential observation data, where omission mistakes of an observer may often occur. It is shown how the omission mistakes can be incorporated into the calculation of the Kappa coefficient without violating the statistic it is based on. The enhanced coefficient is termed Kappa…
