The present study assessed the behavioral and the reasoning performances of 507 school and university students on the four logical principles of logical detachment, particular conversion, particular inversion, and particular contraposition. An adapted version of Wason's four-card problem was administered to all students in paper-and-pencil format and in group settings. Students were asked to respond to the logical questions and to justify their answers. Nine logical reasoning categories were identified. The results of behavioral and reasoning performances were compared across grade levels. Results indicated that many students who responded behaviorally correctly to the logical questions, provided incorrect reasoning justifications. The percentages of students who considered a conditional statement as hypothetical increased with age. No sex differences on the behavioral and the reasoning performances were reported. 相似文献

Controversy in the literature exists concerning the relative importance of cognitive characteristics such as general developmental level and specific prior knowledge for science achievement. Thus the relative ability of developmental level and prior knowledge to predict achievement of concepts of evolution and natural selection was assessed by means by three commonly used types of examination items: multiple choice items, a computational item, and an essay item. The effects of students' disembedding ability, mental capacity, and belief in evolution were also assessed. Disembedding ability, prior knowledge, and belief in evolution were found to be significantly related to overall achievement, while developmental level and mental capacity were not. However, developmental level was found to be the best predictor of performance on the computational item while belief in evolution and prior knowledge were found to be the best predictors of performance on the multiple-choice items. Mental capacity was found to be a predictor of performance on the essay item. It is argued that the cognitive variables influence different aspects of science achievement. Implications are discussed. 相似文献

Although many educators recognize the importance of voice, fostering voice in those who have traditionally been voiceless
has been difficult. This article, like the program that it describes, tackles that challenge by having participants speak
for themselves. Specifically, the participants speak about their involvement in the first year of an alternative teacher education
project. In describing their involvement, the participants focus on their roles and relationships as well as the type of partnership
and collaboration that emerged from this project. 相似文献

A review of the literature reveals that little research has been conducted on the role of the State Supervisor of Guidance Services. More specifically, the literature review did not yield any factor analysis studies on this role. A questionnaire sent to 280 state directors and supervisors of guidance services in the 50 states was the instrument used to gather the data that was subsequently analyzed on an IBM 360, Model 50 computer. The factor analysis yielded three major categories: Promotion, Service, and Noninvolvement. Since this is the only factor study conducted to date on the role of the State Supervisor of Guidances, it should serve as a foundation for similar future studies. 相似文献

Economic Deprivation and Early Childhood Development 总被引:53,自引:0,他引:53
We consider 3 questions regarding the effects of economic deprivation on child development. First, how are developmental outcomes in childhood affected by poverty and such poverty correlates as single parenthood, ethnicity, and maternal education? Second, what are the developmental consequences of the duration and timing of family economic deprivation? And, third, what is the comparative influence of economic deprivation at the family and neighborhood level? We investigate these issues with longitudinal data from the Infant Health and Development Program. We find that family income and poverty status are powerful correlates of the cognitive development and behavior of children, even after accounting for other differences—in particular family structure and maternal schooling—between low- and high-income families. While the duration of poverty matters, its timing in early childhood does not. Age-5 IQs are found to be higher in neighborhoods with greater concentrations of affluent neighbors, while the prevalence of low-income neighbors appears to increase the incidence of externalizing behavior problems. 相似文献

As classrooms continue to diversify, there is an increasing need to understand children’s inclusive behaviours and moral reasoning. Research shows that epistemic beliefs (beliefs about knowing and knowledge) can influence reasoning for adults, but we know little about this relationship in younger children or how classroom contexts relate to epistemic beliefs for moral reasoning. Thirty-one elementary school children (mean age 6.5 years) participated in epistemic beliefs and moral reasoning tasks in the first year of a three-year longitudinal study. Findings showed that while children described objectivist epistemic beliefs (right/wrong answers) about social inclusion, their justifications revealed an unexpected, more complex set of epistemic beliefs. Implications for moral pedagogies are discussed. 相似文献

Due to staffing changes, clinical librarians in a large pediatric health care system needed to streamline how user requests were received and how best to handle the shared workflow. This article describes how REDCap and SAS were implemented to improve the management of requests, capture comprehensive user statistics, and convey the value of the library services through enhanced reporting. 相似文献

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a checking method. However, after a more substantial period of acquisition, students with a low level of mathematical knowledge performed significantly better after receiving checking instructions than those who did not receive checking instructions. In contrast, higher knowledge students were continually disadvantaged by the inclusion of a checking method. The positive effect of checking for lower knowledge students and the negative effect for higher knowledge students in this domain is a further example of the expertise reversal effect. 相似文献

Learning progressions (LPs) are hypothetical models of how learning in a domain develops over time with appropriate instruction. In the domain of genetics, there are two independently developed alternative LPs. The main difference between the two progressions hinges on their assumptions regarding the accessibility of classical (Mendelian) versus molecular genetics and the order in which they should be taught. In order to determine the relative difficulty of the different genetic ideas included in the two progressions, and to test which one is a better fit with students’ actual learning, we developed two modules in classical and molecular genetics and alternated their sequence in an implementation study with 11th grade students studying biology. We developed a set of 56 ordered multiple-choice items that collectively assessed both molecular and classical genetic ideas. We found significant gains in students’ learning in both molecular and classical genetics, with the largest gain relating to understanding the informational content of genes and the smallest gain in understanding modes of inheritance. Using multidimensional item response modeling, we found no statistically significant differences between the two instructional sequences. However, there was a trend of slightly higher gains for the molecular-first sequence for all genetic ideas. 相似文献
