Media comparison studies have long been criticized as an inappropriate research design for measuring the effectiveness of instructional technology. However, a resurgence in their use has recently been noted in distance education for program evaluation purposes. An analysis of the research design will detail why such a methodology is an inappropriate approach to such an investigation. Increased access to such programming does not seem to serve as a satisfactory benefit for the implementation of distance education efforts. Stakeholders desire to prove that participants in distance-delivered courses receive the same quality of instruction off-campus as those involved in the traditional classroom setting. However, the desire to prove that the quality of such distributed offerings is equal to the quality of on-campus programming often results in comparisons of achievement between the two groups of student participants. Statistically, such a research design almost guarantees that the desired outcome will be attained—that indeed distance learners perform as well as campus-based students. 相似文献

This paper describes an effort to develop a survey instrument capable of measuring important aspects of adolescents’ experiences of interest-related pursuits that are supported by technology. The measure focuses on youths’ experiences of connected learning (Ito et al. in Connected learning: an agenda for research and design. Digital Media and Learning Research Hub, Irvine, 2013), an emerging model of learning across settings supported by digital media. Specifically, the instrument aims to measure the depth with which youth are able to engage in an interest-related pursuit, the level of support and encouragement they receive from peers, and the degree to which their pursuit involves performance or media production as an essential feature. The survey also elicits information regarding the connections between youths’ interest-related pursuits and academic goals, the involvement of adults as co-participants in pursuits, and youths’ access to technology tools they deem necessary for their pursuits. The paper reports on results from a pilot study and two rounds of field-testing, in which we evaluated the validity and reliability of the instrument and compared results with evidence from interviews with youth. Our aim was to investigate the feasibility of an approach to measuring youths’ interest-related pursuits to inform future research and evaluation of initiatives focused on digital media and learning. 相似文献

This study was designed to determine the predictive validity of selected admissions variables used by the University of Kentucky College of Medicine. Data for the study were collected from 586 students admitted to the M.D. program from 1961 to 1968. These students were categorized into one of three groups (Successful [SUCC], Successful with Extended Study [SWES], and Lost to Medicine [LTM]) based upon their performance in medical school. A two-way analysis of variance and the use of a post hoc Scheffé method of multiple comparisons indicated significant differences between the SUCC group and the combined SWES and LTM groups. Therefore, the data revealed the predictive ability of two admissions variables and suggested the need for additional research into the subjective variables used in the admissions process. 相似文献

Standardised and other multiple-choice examinations often require the use of an answer sheet with fill-in bubbles (i.e. ‘bubble’ or Scantron sheet). Students with disabilities causing impairments in attention, learning and/or visual-motor skill may have difficulties with multiple-choice examinations that employ such a response style. Such students may request and receive testing accommodations that intend to mitigate these impairments, such as circling responses in a test booklet, which contains both the questions and corresponding multiple-choice answers. The current study evaluated this test accommodation as compared to using a bubble sheet or Scantron on a multiple-choice vocabulary test. College students with (n = 25) and without (n = 76) disabilities completed a vocabulary test under both booklet (accommodated) and bubble sheet (standard) conditions. Results demonstrated that answering in a test booklet, a much preferred response mode, allowed students to attempt significantly more items than using a bubble sheet, improving their overall test scores. Booklet responding tends to improve overall performance, even for students without disabilities, calling into question the specificity and validity of this accommodation. 相似文献

Twin births are increasing at a rapid rate, yet many educational personnel throughout the world are unaware of the needs of twins in school. Stereotypical views of twins as pathologically close or excessively dependent pervade educational policies and practices, despite the fact that twins do not differ from singletons on rates of psychological disturbance. Research shows that many schools implement strict policies for classroom placement of twins, yet the effects of such policies on twins' development and educational attainment are currently unknown. Recommendations for school personnel and future directions for this formative area are discussed. © 2003 Wiley Periodicals, Inc. Psychol Schs 40: 429–438, 2003. 相似文献

Two studies showed that the link between how much students base their self-worth on academics and their math performance depends on whether their identification with math was statistically controlled and whether the task measured ability or not. Study 1 showed that, when math identification was uncontrolled and the task was ability-diagnostic, basing self-worth on academics was unrelated to the students' math performance. When math identification was controlled, however, the more students based self-worth on academics the worse their math performance. Study 2 showed that, when math identification was uncontrolled and the task was ability non-diagnostic, the more students based self-worth on academics the better their math performance. When math identification was controlled, however, students' level of basing self-worth on academics was unrelated to math performance. These results held for females and males even when gender was made salient. In both studies, higher math identification linked to better math performance. 相似文献
