Some have argued for a common language in the field of instructional design in an effort to reduce misunderstandings and simplify a multitude of synonymous terms and concepts. Others feel that this goal is undesirable in that it precludes development and flexibility. In this article we propose an ontology-building process as a way for readers to compare and analyze terms and concepts across theories. This process entails the development of categories that emerge from the literature, and the comparison of theories across categories. Such a process can reveal broader concepts that exist beyond specific theoretical terminology, differences in meanings behind common terms used by theorists, a greater understanding of the theorists’ intent, and discontinuities and gaps within the theoretical literature. 相似文献

Many factors affect an undergraduate student's postbaccalaureate plans. Academic interests, career-related factors, finances, and various psychological and sociological factors all have been found to be related to interest in advanced education. Few studies, however, are gender-specific in examining the relation of parental educational attainment to their children's aspirations. Such data would be helpful in the attempts to understand the continued underrepresentation of women in most fields requiring advanced degrees. All seniors at a large Midwestern university with at least a 3.0 cumulative grade point average planning to graduate in spring or summer of 1986 were sent questionnaires dealing with their postgraduation plans. Of these 1900 surveys, 791 (42%) were returned. Results reported here examine the relation of future educational plans to gender of student, educational level of parent, and field of study. A modeling effect not noted in previous literature is discussed. 相似文献

Relative performance on color and form dimensions during acquisition of two-cue problems by learning-set-sophisticated rhesus monkeys was evaluated with differential reinforcement. Six animals received 24 two-choice problems, each generated from three planometric stimuli, a reference stimulus, an alternate stimulus identical in color but differing in form, and one identical in form but differing in color. The reference stimulus appeared on every trial of a problem and was paired with one or the other alternate on a given trial On half of the problems, the reference stimulus was positive and on the remainder was negative. Acquisition was nearly equivalent on both cue dimensions with positive reference stimuli, but only one dimension was learned with negative reference stimuli. Results were interpreted as unfavorable to attention theory. 相似文献

OBJECTIVES: This study had two primary objectives: First, to examine the nature and co-occurrence of various forms of child maltreatment (sexual, physical, emotional, and witnessing violence) reported by Latina college students, and second, to explore coexisting maltreatment types and acculturation status as possible contributors to long-term adjustment difficulties. METHOD: Participants were 112 Latina undergraduate students categorized by the number of childhood maltreatment types experienced (0, 1, or 2 or more) and acculturation level (1 to 5). The possible effects of co-occurring forms of maltreatment, in conjunction with acculturation status, were investigated with respect to participants' reported trauma symptomatology. Data were collected using self-report measures. RESULTS: Nearly three out of 10 participants (29%) experienced more than one type of child maltreatment and, as expected, these individuals reported greater trauma symptomatology than those reporting either a single type of maltreatment or no maltreatment at all. Those who reported multiple types also endured more severe maltreatment than did respondents who experienced a single type. Acculturation level was neither directly related to trauma symptoms nor did it moderate the lasting correlates of maltreatment among victims. Interestingly, those who experienced a single form of maltreatment reported no more trauma symptoms than did participants who reported no maltreatment history at all. CONCLUSION: This investigation documents a large degree of overlap among various forms of self-reported childhood maltreatment within a Latina college population. The results underscore the need to consider multiple forms of maltreatment, as well as severity, when making inferences regarding potential effects on later functioning. 相似文献

'Mental models' used by automated scoring for the simulation divisions of the computerized Architect Registration Examination are contrasted with those used by experienced human graders. Candidate solutions (N = 3613) received both automated and human holistic scores. Quantitative analyses suggest high correspondence between automated and human scores; thereby suggesting similar mental models are implemented. Solutions with discrepancies between automated and human scores were selected for qualitative analysis. The human graders were reconvened to review the human scores and to investigate the source of score discrepancies in light of rationales provided by the automated scoring process. After review, slightly more than half of the score discrepancies were reduced or eliminated. Six sources of discrepancy between original human scores and automated scores were identified: subjective criteria; objective criteria; tolerances/ weighting; details; examinee task interpretation; and unjustified. The tendency of the human graders to be compelled by automated score rationales varied by the nature of original score discrepancy. We determine that, while the automated scores are based on a mental model consistent with that of expert graders, there remain some important differences, both intentional and incidental, which distinguish between human and automated scoring. We conclude that automated scoring has the potential to enhance the validity evidence of scores in addition to improving efficiency. 相似文献

Authors report here a survey of medical student feedback on the effectiveness of two different anatomy curricula at Christian Medical College, Vellore, India. Undergraduate medical students seeking the Bachelor in Medicine and Bachelor in Surgery (M.B.B.S.) degrees were divided into two groups by the duration of their respective anatomy curriculum. Group 1 students had completed a longer, 18‐month curriculum whereas Group 2 counterparts followed a shorter, 12‐month curriculum. Students' responses to a questionnaire were studied. Analysis of feedback from Groups 1 and 2 contrasted the effectiveness of the two anatomy curricula. The coverage of gross anatomy was rated adequate or more than adequate by 98% of Group 1 and 91% of Group 2. A desire for greater emphasis on gross anatomy teaching was expressed by 24% of Group 1 and 50% of Group 2 (P = 0.000). Two‐thirds of all students felt that the one‐year program was not adequate, and 90% of Group 1 and 74% of Group 2 felt that clinically oriented anatomy teaching required more emphasis. Dissection was helpful or very helpful for 94% of Group 1 and 88% of Group 2. This study suggests that a better understanding of gross anatomy was gained from a course of longer duration (18 months with 915 contact hr vs. 12 months with 671 contact hr). Students who completed the longer anatomy course had greater appreciation of the need for clinically oriented anatomy teaching and dissection.
