We studied students' conceptions of correctness and their influence on students' correctness-related practices by examining how 159 students had analyzed the correctness of error-free and erroneous algorithms and by interviewing seven students regarding their work. We found that students conceptualized program correctness as the sum of the…

Much has been written to convince content-area teachers to include literacy instruction as part of their regular content instruction. The purpose of this study was to determine how the messages available in the literature are framed and how they might be viewed by content-area teachers, especially mathematics teachers. The analysis revealed that…

The experiment examined the effects of exposure to pretrial publicity (PTP) and delay on juror memory and decision-making. Mock jurors read news articles containing negative PTP, positive PTP, or unrelated articles. Five days later, they viewed a videotaped murder trial, after which they made decisions about guilt. Finally, all participants…

In this article we investigated 4th, 6th, and 8th grade students' misconceptions about light, sight, vision, source of light and examined students' conceptual development of these concepts at different grade levels. Data collection was done using five two-tiered test questions with one open-ended question, an interview about concepts and a drawing…

Even though photosynthesis is an obligatory part of the science curriculum, research has shown that students often have a poor understanding of it. The authors advocate that classroom coverage of the topic of photosynthesis should include not only its biochemical properties but also the role of photosynthesis or photosynthetic organisms in matter…

Many students view equations as a series of variables and operators into which numbers should be plugged rather than as representative of a physical process. To solve a problem they may simply look for an equation with the correct variables and assume it meets their needs, rather than selecting an equation that represents the appropriate physical…

Clearly, changing postsecondary finance without a lot of new money to grease the skids will be difficult. The status quo is always easier than change, particularly change that will be objectionable to those who benefited most in the previous system. But political objections aren't the only barrier to changing funding in higher education; a…

The aim of this study was to investigate the effectiveness of conceptual change-based instruction and traditionally designed physics instruction on students' understanding of projectile motion concepts. Misconceptions related to projectile motion concepts were determined by related literature on this subject. Accordingly, the Projectile Motion…

An Arabic version of the Public Opinion Survey of Human Attributes Inventory [POSHA-E; St Louis, K. O. (2005), a global instrument to measure public attitudes about stuttering. ("The ASHA Leader," 22, 2-13)] was administered to 424 Arab parents of preschool and school age children in 18 government schools across all six governorates in…

With the development of e-learning technology, many specifications of instructional design have been proposed to make learning activity sharable and reusable. With the specifications and sufficient learning resources, the researches further focus on how to provide learners more appropriate learning activities to improve their learning performance.…

Can spiraling special education costs explain why educational achievement remained stagnant over the past three decades while real education spending more than doubled? Policy makers, education researchers, and school district officials often make this claim. Special education students--goes the argument--are draining resources away from regular…

Although structural equation modeling (SEM) is one of the most comprehensive and flexible approaches to data analysis currently available, it is nonetheless prone to researcher misuse and misconceptions. This article offers a brief overview of the unique capabilities of SEM and discusses common sources of user error in drawing conclusions from…

This article describes the rationale for, and development of, an online instrument that helps identify commonly held science misconceptions. Science Beliefs is a 47-item instrument that targets topics in chemistry, physics, biology, earth science, and astronomy. It utilizes a true or false, along with a written-explanation, format. The true or…

In this paper, the main points of Lamarck's and Darwin's theoretical conceptual schemes about evolution are compared to those derived from 15 years old students' explanations of evolutionary episodes. We suggest that secondary students' preconceptions should not be characterized as "Lamarckian", because they are essentially different from the…

Content analysis is a powerful empirical method for analyzing text, a method that technical communicators can use on the job and in their research. Content analysis can expose hidden connections among concepts, reveal relationships among ideas that initially seem unconnected, and inform the decision-making processes associated with many technical…
