The issue of literacy retention is central to the educational policy concerning of most developing countries. It has been variously suggested that 4–6 years of primary education may serve as an inoculation against ‘relapse’ into illiteracy in the Third World. This paper reports on one of the first longitudinal studies designed to address this question, by investigating the nature of literacy and cognitive retention in a sample of 72 adolescents two years following fifth grade departure from primary school in Morocco. The present study found that these school leavers, when reassessed two years later, showed a significant increase in performance in first literacy (Arabic), modest gains in second literacy (French), no change in cognitive skills, and a decrement in math skill. Furthermore, urban leavers gained more literacy than rural leavers, and girls more than boys. The present findings do not support the hypothesis of literacy ‘relapse’ or loss of academic/cognitive skills after five grades of primary schooling. It was also found that girls retained more academic skills than boys, but were much less likely to be employed, a finding which calls into question certain claims about the impact of schooled knowledge and literacy on employment in developing countries. 相似文献

The influences of domain-specific meteorological knowledge and general visual–spatial abilities on the comprehension of simple weather maps were examined in a regression-based study involving a sample of participants with relatively low meteorological knowledge and in an experiment involving a contrast between samples of higher- and lower-knowledge participants. Results from the first study indicated that the roles of domain-specific knowledge and visual–spatial abilities for lower-knowledge individuals were strongly influenced by the presence of supporting geographic information (i.e., city locations) in the weather maps being interpreted. Results from the second study underscored the importance of domain-specific meteorological knowledge and map familiarity and, surprisingly, pointed to a single visual–spatial ability (speed of closure) that mediated both of these influences. 相似文献

Coronavirus disease 2019 (Covid-19) created unparalleled challenges to anatomy education. Gross anatomy education has been particularly impacted given the traditional in-person format of didactic instruction and/or laboratory component(s). To assess the changes in gross anatomy lecture and laboratory instruction, assessment, and teaching resources utilized as a result of Covid-19, a survey was distributed to gross anatomy educators through professional associations and listservs. Of the 67 survey responses received for the May–August 2020 academic period, 84% were from United States (US) institutions, while 16% were internationally based. Respondents indicated that in-person lecture decreased during Covid-19 (before: 76%, during: 8%, P < 0.001) and use of cadaver materials declined (before: 76 ± 33%, during: 34 ± 43%, P < 0.001). The use of cadaver materials in laboratories decreased during Covid-19 across academic programs, stand-alone and integrated anatomy courses, and private and public institutions (P ≤ 0.004). Before Covid-19, cadaveric materials used in laboratories were greater among professional health programs relative to medical and undergraduate programs (P ≤ 0.03) and among stand-alone relative to integrated anatomy courses (P ≤ 0.03). Furthermore, computer-based assessment increased (P < 0.001) and assessment materials changed from cadaveric material to images (P < 0.03) during Covid-19, even though assessment structure was not different (P > 0.05). The use of digital teaching resources increased during Covid-19 (P < 0.001), with reports of increased use of in-house created content, BlueLink, and Complete Anatomy software (P < 0.05). While primarily representing US institutions, this study provided evidence of how anatomy educators adapted their courses, largely through virtual mediums, and modified laboratory protocols during the initial emergence of the Covid-19 pandemic. 相似文献

This paper demonstrates that hysteresis operators are the optimal estimators for a large class of estimation and decision problems. This class of problems arises whenever a cost is associated with actions needed to process changes in the estimates or decisions. A simple example related to least-squares estimation is used to illustrate and motivate the developments in this paper. Subsequently, the problem of mean-square estimation with minimal cost of actions is investigated. These results provide a justification for the use of hysteresis in many practical signal processing and communication applications. 相似文献

Interactive query expansion (IQE) (c.f. [Efthimiadis, E. N. (1996). Query expansion. Annual Review of Information Systems and Technology, 31, 121–187]) is a potentially useful technique to help searchers formulate improved query statements, and ultimately retrieve better search results. However, IQE is seldom used in operational settings. Two possible explanations for this are that IQE is generally not integrated into searchers’ established information-seeking behaviors (e.g., examining lists of documents), and it may not be offered at a time in the search when it is needed most (i.e., during the initial query formulation). These challenges can be addressed by coupling IQE more closely with familiar search activities, rather than as a separate functionality that searchers must learn. In this article we introduce and evaluate a variant of IQE known as Real-Time Query Expansion (RTQE). As a searcher enters their query in a text box at the interface, RTQE provides a list of suggested additional query terms, in effect offering query expansion options while the query is formulated. To investigate how the technique is used – and when it may be useful – we conducted a user study comparing three search interfaces: a baseline interface with no query expansion support; an interface that provides expansion options during query entry, and a third interface that provides options after queries have been submitted to a search system. The results show that offering RTQE leads to better quality initial queries, more engagement in the search, and an increase in the uptake of query expansion. However, the results also imply that care must be taken when implementing RTQE interactively. Our findings have broad implications for how IQE should be offered, and form part of our research on the development of techniques to support the increased use of query expansion. 相似文献

Most field work studies report findings but fail to deal with ethical problems encountered during their execution. This paper concentrates on four ethical problems which arose during the conduct of a field work investigation of the life experiences of three student teachers. The four problems were: acquiring permission to begin the study; how far to dig into personal lives to extract necessary information; the pitfalls of doing collaborative research; the more a participant tells, the worse he/she looks. A major implication is that ethical problems given the current bureaucratic and interpersonal climate in urban institutions (universities and city school districts) may be unresolvable, rather than simply a minor hindrance to the researchers and participants. 相似文献

Students of biology must learn the scientific method for generating information in the field. Concurrently, they should learn how information is reported and accessed. We developed a progressive set of exercises for the undergraduate introductory biology laboratory that combine these objectives. Pre- and postassessments of approximately 100 students suggest that increases occurred, some statistically significant, in the number of students using various library-related resources, in the numbers and confidence level of students using various technologies, and in the numbers and confidence levels of students involved in various activities related to the scientific method. Following this course, students should be better prepared for more advanced and independent study. 相似文献

Student evaluations of their classes and instructors are widespread in higher education and have both practical and theoretical importance. This study examined the relationship between class average evaluations and characteristics of the instructor and of the class in an off-campus setting with nontraditional students. A stepwise multiple regression analysis found that four variables—the time format of the class, the number of classes taught in the program by the instructor during the year, whether a term paper was required, and the size of the class—explained 13.5% of the variance in class average evaluations. The addition of average class grade increased the explained variance by 6%. Evaluations were higher in classes taught with more intensive time formats, in classes taught by instructors teaching more frequently in the program, in classes where term papers were required, and in classes with fewer students. Evaluations were also higher in classes where the average class grade was higher. Other course and instructor characteristics had little or no effect on overall class evaluations. The results support the view that nontraditional students react similar to traditional students in their evaluations of their classes. The results also suggest the importance of time format as a factor affecting class evaluations.An earlier version of this paper was presented at Western Psychological and Rocky Mountain Psychological Association Meeting, April 1989. 相似文献

AbstractEducators and policy makers must confront the race and class disparities in learning opportunities across American society. Nowhere are these disparities more acute than in the country's great metropolitan areas. As the demographic landscape continues to shift, metropolitan areas are fueling the transition to a majority-minority country. This essay provides an overview of the challenges for the country's public schools and offers an alternative path to creating a more just and vital society. 相似文献
