Pigeons were trained in an intratrial interference preparation in which a horizontal or vertical line was presented for 1 sec immediately following termination of a sample (red or green). Two samples were presented successively on interference trials. Choice of the comparison corresponding to the second (target) sample was designated correct and was reinforced, and choice of the comparison corresponding to the first (interfering) sample was designated incorrect and was not reinforced. Control trials involved the presentation of a single, target sample. A horizontal line was presented upon termination of an interfering sample, and a vertical line was presented upon termination of a target sample. The results of three experiments led to the conclusion that the horizontal line acquired and capacity to reduce postperceptual processing (rehearsal) of information derived from an immediately preceding sample stimulus. These findings include (1) convergence of accuracy on control and interference trials as training progressed, (2) a reduction in accuracy on control and especially on interference trials when the correlation between sample type (interfering or target) and cue type (horizontal or vertical) was reduced to zero, (3) higher accuracy (i.e., less interference) when the horizontal rather than the vertical line followed the interfering sample, and (4) higher accuracy on single-sample trials when the vertical rather than the horizontal line followed sample presentation. 相似文献

This study explored factors that contribute to students’ concepts of magnification and scale. Spatial visualization, logical
thinking, and concepts of magnification and scale were measured for 46 middle school students. Scores on the Zoom Assessment (an assessment of knowledge of magnification and scale) were correlated with the Test of Logical Thinking (TOLT) and a series of four spatial visualization tests. Results showed that the TOLT was significantly correlated with the
Zoom Assessment. There was also a significant correlation between the TOLT and spatial visualization assessments MV1 (Shape Memory), MV2 (Building Memory), the Storage Test, and the Surface Development Test. The implications of this study for further research are discussed. 相似文献

Writing samples of children in grades one through three were collected in two midwestern elementary schools using the Picture
Story Language Test. Each story was scored for productivity, syntax, and level of abstraction. Results indicated that performance
in all aspects of written language improved with age.
A second study was conducted to compare the writing of normal children who were average readers in grades one through three
with learning disabled children who were reading at comparable levels. The results indicated no significant differences in
productivity but there were differences in syntax. Problems were noted particularly in morphology. Further observations indicated
the learning disabled poor readers also had more problems with handwriting and spelling than average readers. 相似文献

In response to concern over the numeracy skills deficit displayed by student nurses, an online computer programme, “Authentic World®”, which aims to simulate a real-life clinical environment and improve the medication dosage calculation skills of users, was developed (Founded in 2004 Authentic World Ltd is a spin out company of Glarmorgan and Cardiff Universities, Cardiff, Wales UK.). Two randomised controlled trials were conducted, each at a UK University, in order to investigate the impact of Authentic World® on student nurses’ general numeracy abilities. All first year nursing students who gave consent were randomised equally into an intervention or control group. The intervention group were given access to Authentic World®. The primary outcome measure was the students’ scores on a general numeracy test. The Intention to Treat (ITT) analysis in both trials revealed a small negative effect of Authentic World® on general numeracy, which was statistically significant in one trial. However, compliance with the intervention was very low in both trials, with only 24 and 12% of students allocated to the intervention groups spending more than 15 minutes using the programme. Providing nursing students with access to Authentic World® is not an effective use of resources since use of the programme appears to be very low. 相似文献

This paper explores the nature of Information Management (IM) pedagogic practice within UK higher education (HE), by exploring the history of IM and teasing out what this may mean for its teaching. Empirical evidence is considered from both qualitative and quantitative data analysis perspectives through the application of Grounded theory. 相似文献

Dynamic assessment uses a response‐to‐instruction paradigm to complement traditional diagnostic assessment of word recognition and comprehension. The process helps the examiner to predict appropriate remedial intervention by exploring a student's responses to a series of instructional episodes in an interactive teaching‐learning relationship. Dynamic and traditional (or static) assessment differ in orientation (process vs product), procedure (response to instruction vs enumeration of existing abilities), and interpretation (patterns of response to instruction vs indices, for example percentiles or stanines). A dynamic approach to assessment provides the opportunity to evaluate systematically the instructional factors that influence reading performance. 相似文献

Gordon and his associates (e.g., Gordon & Feldman, 1978,Learning and Motivation,9, 164–178; Feldman & Gordon, 1979,Learning and Motivation,10, 198–210; Gordon, Taylor, & Mower, 1981,American Journal of Psychology,94, 309–322) have reported that a reactivation treatment significantly enhances memory for prior forcings in delayed alternation using rats. The reactivation treatment consisted of placing the rat in the goal arm to which it had been forced previously on that trial. The confinement occurred in the absence of food and was 5 sec in duration. The present experiments explored the possibility that the treatment might influence performance by affording an opportunity for new information to be acquired during the confinement period. Evidence consistent with this view was found in that (1) accuracy was reduced on trials in which the initial event was a 5-sec confinement to the arm opposite that of the target forcing and (2) increasing the duration of the confinement from 5 to 15 to 45 sec increased the magnitude of this effect. It was concluded that the effectiveness of goal-arm confinement as a reactivation treatment does not necessarily implicate processes of retrieval in delayed alternation behavior. 相似文献
