Characteristic-Based, Task-Based, and Results-Based: Three Value Systems for Assessing Professionally Produced Technical Communication Products

Technical communicators have developed different methodologies for evaluating the effectiveness of their work (whether the information can be used by the intended audience), such as editing, usability testing, and determining the value-added. But, as vastly differing assessments of the same professionally produced technical communication products suggest, at least three broad value systems underlie the assessment practices: characteristic-based (assessing against a set of criteria), task-based (assessing users' observed ability to perform tasks), and results-based (assessing the contribution to the publisher, usually in financial terms). The systems do not overlap with one another; rather, they embody different values about what makes technical communication effective. The most complete form of assessment may involve multiple assessment approaches and triangulated results.     

The incidence and wage effects of overeducation

Data gathered from a recent national sample of workers on educational requirements and attainments are used to examine the extent and economic effects of overeducation. Nearly 40 percent of the U.S. work force-and about 50 percent of black males-have more education than their jobs require. But we also find that “surplus” education does have economic value. The individual return to an additional year of surplus education was positive and significant for all major demographic groups. The estimated return is, however, only about half the size of the return to an additional year of required education.     

Giving priority to evidence in science teaching: A first‐year elementary teacher's specialized practices and knowledge

The purpose of this qualitative case study was to examine the nature of a first‐year elementary teacher's specialized practices and knowledge for giving priority to evidence in science teaching and to explore the possible sources from which this knowledge was generated. Data included three audiotaped interviews, six videotaped classroom observations, lesson plans, and samples of students' work. The findings of this study reveal that the teacher gave priority to evidence by frequently engaging students in collecting evidence through observations and investigations, recording and representing evidence, and using that evidence to construct explanations. The findings of this study also illustrate that critical experiences during preparation to teach and specific university coursework acted as sources through which the teacher's specialized knowledge for giving priority to evidence was generated. © 2005 Wiley Periodicals, Inc.
