The elements of desirable research design for the evaluation of educational technology are discussed with reference to the context of existing research. Sources of internal invalidity, type of compared educational activity, and outcome measures are considered. Finally, recommendations regarding the direction of evaluation research are made. Research designs that take into account the characteristics of the learner, the software, and the teacher preferably within the framework of a model of the learning process should be adopted. 相似文献

The aims of this study of HIV-1 positive and HIV-1 negative gay males without disease were (a) to determine whether cynical hostility in these groups (measured by the Cook-Medley Ho scale) is associated with psychosocial deficits that potentially could influence the course of HIV infection; and (b) to examine the construct validity of the sum of three Ho subsets in this sample. Correlational analyses on the full samples, and multivariate analyses of high- and low-hostility groups (formed using Ho scale cutoffs from previous research), examined person variables (traits, coping style), environmental variables (social support, stressors), and affect. In all domains other than stressors (traits, coping styles, social support, and affect), cynical hostility was associated with psychosocial deficits, with results generally stronger for the full Ho scale than for the subset sum. Results support previous research on psychosocial deficits of the cynically hostile, extend findings to HIV-infected gay males, and enlarge our understanding of the trait and coping style correlates of cynical hostility. Implications of these findings for HIV infection are discussed. 相似文献

There has been a burgeoning interest in studying daily events and experiences. This article discusses a variety of methodologic challenges that face daily event and experience researchers. The issues discussed include techniques for measuring events, the development of event checklists, sampling event content, specifying event appraisals, event validation procedures, and the creation of summary measures derived from event checklists. Procedural issues discussed include determining the number of observations and persons needed for daily event studies, the evaluation of response, attrition, and missing item bias, and problems linking event reports over time. 相似文献

Temporal coding in rhythm tasks revealed by modality effects 总被引:1,自引:0,他引:1
Temporal coding has been studied by examining the perception and reproduction of rhythms and by examining memory for the order of events in a list. We attempt to link these research programs both empirically and theoretically. Glenberg and Swanson (1986) proposed that the superior recall of auditory material, compared with visual material, reflects more accurate temporal coding for the auditory material. In this paper, we demonstrate that a similar modality effect can be produced in a rhythm task. Auditory rhythms composed of stimuli of two durations are reproduced more accurately than are visual rhythms. Furthermore, it appears that the auditory superiority reflects enhanced chunking of the auditory material rather than better identification of durations. 相似文献

The present study investigated the effects of self-perceptions on the donating behavior of 43 fourth-grade students. The children had two opportunities to donate gum to another class. Half of the students received feedback after the first donation period indicating that they were particularly generous. These children subsequently gave more than children in the control group (p<.05). Sociometric measures indicated that the perceptions children had of themselves and others were related to donating. The results were similar for both males and females. Children process new information into their cognitive systems. The resulting cognitions help guide future behaviors. 相似文献
