Research on memory for time has been limited by the difficulty of disentangling several of the fundamentally different processes that contribute to a chronological sense of the past. This study used a developmental approach to isolate one of these processes, impressions of distances in the past. Large samples of children between 3 and 12 years were asked to judge which was longer ago, their birthday or Christmas (and, in one study, Halloween and Thanksgiving). Even children under 6 years of age were able to discriminate the recency of their birthday and Christmas with great accuracy when the events were widely separated and one was within the past several months. The ability to discriminate recency on these scales appears to be a basic property of human memory that changes little with development. Other information about the locations of the events and their relative times of occurrence could only be interpreted correctly by children older than 9 years.  相似文献

Isotopes can be used as markers to keep track of positions of atoms during a chemical transformation. This strategy of determining reaction mechanisms is illustrated in the article with several examples.  相似文献

A case study was conducted of mathematics instruction at five sites in Papua New Guinea. Trial instructional materials were developed, teachers received inservice training and implementation was carefully monitored for a six-week period. English and mathematics achievement instruments and eight measures of cognitive development were administered to a sample of 201 students in grades two, four and six. Mathematics and language achievement varied significantly among the five sites. Students at all grade levels exhibited poor application of problem solving skills while showing computation, measurement and mathematical language abilities superior to results previously reported. English reading and measures of conservation and classification competence were highly correlated with mathematics achievement. Correlations between memory measures and mathematics achievement decreased from grade two to grade six while correlations between measures of language and cognitive development and mathematics achievement tended to increase. The results indicated that the non-consumable student textbooks ameliorated to some extent the problems associated with non-native language instruction for the students involved in the study. It was concluded that locally developed textbooks with an appropriate language load would enhance mathematics learning, particularly in remote-rural areas where current teaching conditions and lack of materials interact with poor English skills to create an imbalance in achievement.  相似文献

Face‐to‐face education and distance education, viewed as differing sets of organisational provisions for the fostering of learning, emphasize different kinds of learning processes, and depend upon somewhat different psychological properties in learners. Nonetheless, all practical learning settings, whether they are labelled ‘school’, ‘adult education’, ‘distance education’, or something else, involve a mixture of face‐to‐face learning and distance learning. The psychological difference between the two kinds of setting is thus note purely qualitative in nature, but is also quantitative: for instance, certain learner characteristics which are useful in face‐to‐face learning (discussed in detail in the body of the present paper) are indispensible for distance learning, while certain processes which are at the heart of distance learning (also dis‐cusssed in detail later) are often given little emphasis in face‐to‐face settings, although they are in principle possible and even desirable there. The question thus arises of whether it would not be desirable to give more emphasis in face‐to‐face settings to psychologically desirable aspects of distance learning.  相似文献

This study investigated the interscorer reliability between a novice and a professional psychologist for the Minnesota Percepto-Diagnostic Test-Revised (MPDT-R). The sample consisted of 30 individuals (18 males and 12 females) who were referred to the Applied Neuroscience Institute of the University of Maryland Eastern Shore. Results from the study indicated that for three of the four MPDT-R scores there was a significant positive correlation between expert and novice scoring criteria. Implications for the assessment of perceptual-motor problems using the MPDT-R are discussed.  相似文献

There is a need for accurate, efficient assessment of children's readiness, to provide information concerning strengths and weaknesses of children and to identify those children who may be at risk for school failure. This necessitates determining the relative usefulness of instruments in predicting later school achievement. This study examined the efficacy of the McCarthy Screening Test (MST) and Metropolitan Readiness Test (MRT) to predict academic readiness at the end of kindergarten and achievement at the end of first grade. Eighty-eight children were screened upon entering kindergarten, using the MST. As a measurement of academic readiness, the MRT was administered at the end of kindergarten, and the Scott and Foresman Achievement Test (SFAT) was administered at the end of first grade as a measure of achievement. Regression analyses indicated that the MST significantly predicted children's scores on the MRT and SFAT. Additionally, the MRT was a significant predictor of the SFAT.  相似文献

Salary comparisons: New methods for correcting old fallacies   总被引:1,自引:0,他引:1  
Institutions of higher education place high priority on ensuring that their faculties are adequately paid. Since gauging the adequacy of compensation is a problem of relative measure, this assessment is usually performed by comparing university-level average salaries for a group of peer institutions. Often the potential distortions caused by differences in the rank mix of the faculty are forestalled by comparing average salaries for each of the four ranks. However, few if any institutions take similar steps to prevent the skewing of averages owing to differences in cost of living, differences in distribution of faculty in academic year and twelve-month appointments, and differences in the configuration of the faculty over disciplines. This paper shows that salary comparisons that do not compensate for these variation in staff mix are seriously flawed. A recommended methodology is demonstrated.  相似文献
