ABSTRACTThis paper intends to present an interdisciplinary project carried out in a School of Engineering, and to refer to its effects in the development of students’ skills. This project’s main goal was to present students with an intellectually demanding challenge which implied overcoming the disciplinary barriers thus integrating knowledge to solve the problems they were challenged with. After the project had been concluded, a study was carried out using a qualitative methodology by conducting two focus groups (n?=?16). The main goal of this procedure was to get a better perception of (1) how students understood the project; (2) what kind of skills students considered to have developed throughout the project, and (3) the importance they have attributed to this kind of project. The results demonstrate that students are aware of the relevance of the project not only for their education process but also for the development of their skills. The results of the study also reveal that the students involved in the project have been capable of identifying the specific skills that the project work had intended to address and develop. 相似文献

In three experiments, we show that people respond differently when they make predictions as opposed to when they are asked
to estimate the causal or the predictive value of cues: Their response to each of those three questions is based on different
sets of information. More specifically, we show that prediction judgments depend on the probability of the outcome given the
cue, whereas causal and predictivevalue judgments depend on thecue-outcome contingency. Although these results might seem problematic for most associative models in their present form, they can be explained by
explicitly assuming the existence of postacquisition processes that modulate participants’ responses in a flexible way. 相似文献

In three experiments in which rats were used as subjects, we developed an extinction procedure using a Morris pool. The animals were trained to find a hidden platform located at a fixed position and were then given extinction trials in which the platform was removed from the pool. When training and extinction were carried out in the same context and time was allowed to elapse between extinction and test, spontaneous recovery of learning was observed. On the other hand, those rats that received extinction in a context different from the one used for training failed to show spontaneous recovery of learning when tested in the extinction context after an interval of 96 h. However, they did show renewal of spatial learning when tested in the training context. These results show that extinction in the spatial domain behaves like extinction in standard conditioning preparations. 相似文献

Experimental high-energy and nuclear physics was created in Spain thanks to Joaquín Catalá de Alemany, who founded the Institute of Corpuscular Physics (IFIC) at the University of Valencia in 1950. The physics of photographic emulsions, cheap and easy to manipulate, were well adapted to the depressed situation in Spain following the Civil War. This essay describes how, using these techniques, Catalá de Alemany created a group, established links with international laboratories, and fostered a tradition that continues today. 相似文献

Cognitive interviewing (CI) provides a method of systematically collecting validity evidence of response processes for questionnaire items. CI involves a range of techniques for prompting individuals to verbalise their responses to items. One such technique is concurrent verbalisation, as developed in Think Aloud Protocol (TAP). This article investigates the value of the technique for validating questionnaire items administered to young people in international surveys. To date, the literature on TAP has focused on allaying concerns about reactivity – whether response processes are affected by thinking aloud. This article investigates another concern, namely the completeness of concurrent verbalisations – the extent to which respondents verbalise their response processes. An independent, exploratory validation of the PISA assessment of student self-efficacy in mathematics by a small international team of researchers using CI with concurrent verbalisation in four education systems (England, Estonia, Hong Kong, and the Netherlands) provided the basis for this investigation. The researchers found that students generally thought aloud in response to each of the items, thereby providing validity evidence of responses processes varying within and between the education systems, but that practical steps could be taken to increase the completeness of concurrent verbalisations in future validations. 相似文献

Food-deprived rats that receive intermittent delivery of small amounts of food develop excessive drinking--specifically, schedule-induced polydipsia (SIP). A main characteristic of SIP is its occurrence at the beginning of interfood intervals. The purpose of this study was to demonstrate that SIP can be developed toward the end of interfood intervals, in closer proximity to upcoming than to preceding food delivery. In Experiment 1, two groups were exposed to a fixed-time (FT) 30-sec food schedule with water available during the first or the last 15 sec of each interfood interval. Two additional groups, which had access to water throughout, were exposed to FT 30-sec or FT 15-sec schedules of food presentation. The FT 30-sec group with free access to water developed the highest level of intake; similar and intermediate levels were induced in all the remaining groups. In Experiment 2, three groups of rats were exposed to an FT 90-sec food schedule with water available during the first, the second, or the last 30 sec of each interfood interval. One additional group with access to water throughout was exposed to the FT 90-sec schedule of food presentation. The group with free access to water developed a higher level of consumption than did the other groups, but by the end of training none of the four groups showed statistical differences in polydipsic drinking. Results show that adjunctive drinking can be developed in proximity to upcoming food delivery even with long interfood intervals. 相似文献

This study examined whether short-term maximal resistance training employing fast-velocity eccentric knee extensor actions would induce improvements in maximal isometric torque and rate of force development (RFD) at early (<100 ms) and late phases (>100 ms) of rising torque. Twenty healthy men were assigned to two experimental groups: eccentric resistance training (TG) or control (CG). Participants on the TG trained three days a week for a total of eight weeks. Training consisted of maximal unilateral eccentric knee extensors actions performed at 180°s-1. Maximal isometric knee extensor torque (MVC) and incremental RFD in successive 50 ms time-windows from the onset contraction were analysed in absolute terms (RFDINC) or when normalised relative to MVC (RFDREL). After eight weeks, TG demonstrated increases in MVC (28%), RFDINC (0–50 ms: 30%; 50–100 ms: 31%) and RFDREL (0–50 ms: 29%; 50–100 ms: 32%). Moreover, no changes in the late phase of incremental RFD were observed in TG. No changes were found in the CG. In summary, we have demonstrated, in active individuals, that a short period of resistance training performed with eccentric fast-velocity isokinetic muscle contractions is able to enhance RFDINC and RFDREL obtained at the early phase of rising joint torque. 相似文献
