Review of: National Institutes of Health Curriculum Supplements: Human Genetic Variation and Cell Biology and Cancer,by Biological Sciences Curriculum Study and Videodiscovery; 1999; http://science.education.nih.gov/customers.nsf/highschool.htm 下载免费PDF全文
The National Institutes of Health publishes a series of science curriculum supplements for K–12 education that are available from their Web site free of charge (http://science.education.nih.gov/supplements). In this feature, we review two of the high school supplements, Human Genetic Variation and Cell Biology and Cancer. Overall, we find that they are both excellent resources that engage students in learning science content while emphasizing the impact of scientific breakthroughs on personal and public health. In this review, we highlight the many strong features of the curricula and point out instances in which teachers may wish to seek out supplemental, updated information. 相似文献

ABSTRACTPrevious studies found a relationship between performance on statistical learning (SL) tasks and reading ability and developmental dyslexia. Thus, it has been suggested that the ability to implicitly learn patterns may be important for reading acquisition. Causal mechanisms behind this relationship are unclear: Although orthographic sensitivity to letter bigrams may emerge through SL and facilitate reading, there is no empirical support for this link. We test 84 adults on two SL tasks, reading tests, and a bigram sensitivity task. We test for correlations using Bayes factors. This serves to test the prediction that SL and reading ability are correlated and to explore sensitivity to bigram legality as a potential mediator. We find no correlations between SL tasks and reading ability, SL and bigram sensitivity, or between the SL tasks. We conclude that correlating SL with reading ability may not yield replicable results, partly due to low correlations between SL tasks. 相似文献

Students with disabilities continue to be denied literacy rich experiences with their non-disabled peers. Throughout this article the authors explore how narrow, ability-focused teacher dispositions can perpetuate low expectations and can preemptively deny students with disabilities access to meaningful literacy experiences. Hence, the development of an inclusive literacy disposition is crucial to providing access to robust learning experiences for students with disabilities. The authors describe a research study that utilizes journal writing and a role-play intervention with pre-service general educators in a graduate literacy methods course. Analysis of post-intervention data suggests it is possible to shift narrow, ability-orientated dispositions to broader and more inclusive conceptualizations that support students with disabilities. Implications for both research and practice are discussed. 相似文献

Abstract This qualitative study examines semi-structured interviews with four Norwegian teachers to explore how they teach biblical texts in upper secondary religious education (RE). The theoretical framework combines one model from biblical hermeneutics with one from RE. The former differentiates between the worlds behind, in, and in front of the biblical text, the latter between the universal, common religious, and religion-specific dimensions of religious narratives. Chief findings: All teachers utilize examples from the reception history of the biblical texts; they thus extend Ricoeur’s notion of the world in front of the text. The common religious aspects of biblical texts are mostly overlooked. 相似文献

Today's Edisons or weekend hobbyists: technical merit and success of inventions by independent inventors 总被引:1,自引:0,他引:1
We set out to determine if independent inventors can be considered “heroes” or “hobbyists”, that is, if they produce the most or the least influential inventions in a product category. We study patented inventions by independent and firm-based inventors by comparing patents along four dimensions: Patent citation impact, detail, scope, and maintenance. Examining 225 tennis racket patents granted in the US between 1981 and 1991, we find that independent inventors are a heterogeneous group who generate inventions that are overrepresented both among the most impactful and the least impactful patents. The metrics we develop provide insight into ex ante identification of the importance of inventions. 相似文献

The midsession reversal task involves a simple simultaneous discrimination that predictably reverses midway through a session. Under various conditions, pigeons generally both anticipate the reversal and perseverate once it has occurred, whereas rats tend to make very few of either kind of error. In the present research, we investigated the hypothesis that the difference in performance between rats and pigeons is related to the nature of the responses made. We hypothesized that rats could have been better at bridging the intertrial interval by keeping the relevant paw close to the lever while eating, whereas the pigeons had to remove their beak from the response key and insert it into the feeder, thus making it difficult to mediate the response last made. In the present experiment, in successive phases, rats were trained to leverpress or nose-poke on a 40-trial midsession reversal, an 80-trial midsession reversal, and a variable-location reversal. The results showed that the leverpress group acquired the task faster than the nose-poke group, but that both groups reached comparable levels of performance. Thus, the difference in the natures of the responses cannot fully account for the differences in accuracy between rats and pigeons. Additionally, differences in the types of errors made by the two groups suggest that the nature of the response plays different roles in the performance of this task. 相似文献

Rapidly becoming the largest ethnic group of American students, compared to White students with disabilities, Latino students with disabilities receive less services and their parents are more likely to struggle to receive services. Yet, it is unclear how Latino families advocate for their children with disabilities including how cultural values facilitate their advocacy efforts. In this study, four focus groups were conducted with 46 Latino parents of children with autism spectrum disorder. Parents reported advocating by being assertive but not aggressive, being involved in school activities, communicating with the school and documenting the communication, and relying on knowledge and faith. Parents also reported facilitators (i.e., knowledge and resources, increased parent-school communication, and greater peer support) and barriers (i.e., poor school experiences, school related-stress, and stigma and discrimination) to advocacy. Implications for research, policy, and practice are discussed. 相似文献

Having regained independence from Russia in 1990, Lithuania is in the process of developing a social service system to meet the needs of its older citizens. This paper describes the current situation of older persons in Lithuania and the early stages of gerontology education and gerontological service provision in that nation. Future social service providers (n = 22) who participated in one of Lithuania's first gerontological education training programs completed the 17 items of Kogan's Attitudes Toward Old People Scale. Results indicate that future service providers hold generally neutral to positive attitudes toward older persons. The absence of negative attitudes toward older persons among the first generation of Lithuanian gerontological service providers bodes well for the development of gerontology education and services for older persons in Lithuania. 相似文献

This paper serves as a summation of literature on children's attitudes toward older adults and aging. Research indicates that the vast amount of information available provides varying levels of understanding toward children's actual views of older adults. Differences between measurements, settings, and procedures stand as barriers in cross-comparison of studies and findings. There is a need for early aging education and as well as consistent research methods. 相似文献

This article reports about the development and validation of a measurement instrument assessing elementary school students' achievement emotions (Achievement Emotions Questionnaire-Elementary School, AEQ-ES). Specifically, the instrument assesses students' enjoyment, anxiety, and boredom pertaining to three types of academic settings (i.e., attending class, doing homework, and taking tests and exams). Scale construction was based on Pekrun's (2006) control-value theory of achievement emotions. The instrument was tested using samples from German and American elementary school classrooms. The results of Study 1 (German sample) corroborate the reliability and structural validity of the new emotion measure. Moreover, they show that students' achievement emotions were linked with their control and value appraisals as well as their academic performance, thus supporting the external validity of the measure as well as propositions of Pekrun's (2006) control-value theory of achievement emotions. Study 2 (American sample) corroborated the cross-cultural equivalence of the measure and the generalizability of findings across the German and American samples. Implications for research on achievement emotions and educational practice are discussed. 相似文献
