Presenting narrative text in computer-based instruction (CBI) is more difficult than in print lessons due to limited screen
resolution and display area. The present research aimed at achieving a more compatible match between lesson content and the
attributes of the presentation media. Subjects received either a print or CBI statistics lesson containing low-density (concise)
narrative text, high-density (conventional) text, or the density type they preferred (learner-control). Results showed the
low-density lesson to reduce completion time relative to the high-density version, while yielding equivalent achievement.
Subjects receiving the lesson in the print mode had shorter completion times and higher achievement than their CBI counterparts.
Attitude results showed that CBI was favorably regarded, but perceived as longer and slow-moving than print. Implications
of results for designing instructional material in accord with CBI attributes and learner characteristics are discussed. 相似文献

In some situations children fail to perform optional conceptual processing that they are able to perform. The purpose of the 4 experiments was to determine if the difficulty of word identification affects optional conceptual processing by second/third graders, fifth graders, and college students in a cued recall task. Conceptual processing was manipulated by presenting Hard (e.g., hawk eagle canary) or Easy (river lake canary) word triplets that varied in the contrastive processing necessary to identify the "odd" target word (canary). The orienting activity also varied: for the Oddity Choice activity, contrastive processing was obligatory because the subject had to identify the target; for the Read activity, contrastive processing was optional because the experimenter identified the target. A recall advantage for the Hard over the Easy triplets was the measure of contrastive processing. Finally, the difficulty of word identification varied in that the subjects read the stimuli or the experimenter read the stimuli, and all the words were degraded, only the nontarget words were degraded, or all the words were intact. The results established that contrastive processing facilitates recall, and that word identification difficulty may limit the extent of optional contrastive processing. 相似文献

Using critical race theory, this article examines the racial positioning of British international minority ethnic (IME) academics in predominantly White institutions (PWIs). Empirical data, in the form of 28 in-depth interviews with IME academics, is used to analyze the complex raced and gendered positionalities of IME academics in institutions of higher education in the United States. We argue that the institutional contexts of predominantly White universities continue to re-affirm White privilege in ways that reflect the struggles in higher education to diversify faculty at PWIs. As scholars call for more diversity across higher education campuses, we suggest that it is important to understand the interconnections between policy and practice surrounding attempts to recruit and retain IME academics. 相似文献

The article makes a case for the construction of narratives as major focus for career planning. Narratives can be seen as an appropriate compliment to the analysis of objective test data that has dominated our practice in the past. Narrative is described as an approach for career counselors to understand clients' vocational experiences and future plans. Subjective and objective aspects of a career narrative are explored, and emphasis is placed on co-authoring a career story that is subjectively meaningful and objectively sound. The client's subjective understanding of the career story is given importance as being pivotal information that must be considered in career counseling. Five key interventions are described from a narrative perspective. 相似文献

Some students in the upper elementary grades and high schools may benefit from extended decoding and spelling instruction. These students, because of their age level and reading selections, require strategies going well beyond phonics. For these older readers, including adults, learning about morphological structure may provide the strategies needed to decode and spell multisyllabic words found often in literature and content area texts. In this paper, literature providing a rationale for such instruction is reviewed, and a curriculum and instructional plan is described. 相似文献

OBJECTIVE: For successful prosecution of child sexual abuse, children are often required to provide reports about individual, alleged incidents. Although verbally or mentally rehearsing memory of an incident can strengthen memories, children's report of individual incidents can also be contaminated when they experience other events related to the individual incidents (e.g., informal interviews, dreams of the incident) and/or when they have similar, repeated experiences of an incident, as in cases of multiple abuse. METHOD: Research is reviewed on the positive and negative effects of these related experiences on the length, accuracy, and structure of children's reports of a particular incident. RESULTS: Children's memories of a particular incident can be strengthened when exposed to information that does not contradict what they have experienced, thus promoting accurate recall and resistance to false, suggestive influences. When the encountered information differs from children's experiences of the target incident, however, children can become confused between their experiences-they may remember the content but not the source of their experiences. CONCLUSIONS: We discuss the implications of this research for interviewing children in sexual abuse investigations and provide a set of research-based recommendations for investigative interviewers. 相似文献
