Minority student attrition and underachievement is a long-standing and widespread concern in higher education. It is especially acute in introductory science courses which are prerequisites for students planning to pursue science-related careers. Poor performance in these courses often results in attrition of minorities from the science fields. This is a particular concern at selective universities where minority students enter with excellent academic credentials but receive lower average grades and have lower retention rates than majority students with similar credentials. This paper reports the first year results of a large scale peer-facilitated workshop program designed to increase performance and retention in Biology, Chemistry, and Physics at a selective research university. After adjusting for grade point average or SAT-Math score, workshop participants earned higher final grades than nonparticipants in Biology and Chemistry, but not in Physics. Similar effects on retention were found. While, positive effects of the program were observed in both majority and minority students, effect sizes were generally largest for minority students. Because of practical constraints in Physics, implementation of the program was not optimal, possibly accounting for the differential success of the program across disciplines. 相似文献

We present, in this article, an investigation about the potential of the relationship between formal and non-formal educational environments. Therefore it is not an empirical research, but an essay on the topic. This paper demonstrates the concept that science education and science outreach can be privileged by actions that are developed by closer relations between formal and non-formal places. Currently, non-formal environments such as museums and science and technology centres are considered potential educational resources within the reach of schools. Educators from museums have conducted studies which demonstrate a predominant model of the utilization of these institutions by teachers, which consists of illustrative visits during the exhibitions, but does not feature a collaborative relationship or partnership between schools and these institutions. In Brazil, the main examples of approaches to collaboration between these places and schools have been taking place through the initiatives of teachers or through projects developed by the educational sector, aiming to broaden the dialogue between their institutions and the school community. Another approach mechanism relates to research and extension projects developed by university researchers, sponsored by state and federal funding agencies. In this case, the universities and university museums appear as new social actors that stand in the way of the schools and the cultural environments, complicating the relationship and, at the same time, bringing new questions to the field of educational research. We believe that the discourse in this paper should bring about further discussions in the initial teacher training courses to contribute to the understanding of practices related to the extension of the field of activity of the school. 相似文献

In this study, we aim to understand the forces driving assessment for learning (AfL) in primary school teaching. By applying a case study design, including the two cases of Norway and Portugal and using mathematics teaching as an example, available policy documents and research reports are analysed to identify the differences and similarities that might explain the assessment practices previously observed in the two countries. Many similarities are found at the school and national levels. In particular, AfL is introduced as a national policy in both countries. Still, AfL practices are not common in primary mathematics classrooms in either country, although this is true for different reasons in each country. It is suggested that the assessment culture caused by national policies, such as curriculum reforms, national professional development projects and teacher autonomy, explains the similarities in the observed outcomes. 相似文献

Reciprocal teaching is one of the most successfully implemented cooperative learning practices, yet many aspects of the process it follows are still unclear. The authors' aim was two-fold: To analyze whether reciprocal teaching activates diversity in discourse moves, communicative functions, and interaction sequences; and to determine whether reciprocal teaching needs to be based on prior work on student collaboration and cooperation skills in order to be effective (context dependency vs. context independency). Two groups with a different instructional background were compared: one with a teacher-centered and one with a student-centered approach. Forty-three third-grade students were led through a reciprocal teaching reading activity. Video recordings of each group were transcribed and analyzed at the micro level. Frequencies for each category were described and interpreted. The two groups did not differ significantly in the processes followed, indicating that reciprocal teaching is context independent and able to create interaction-rich and diverse environment. 相似文献

Adults process speech incrementally, rapidly identifying spoken words on the basis of initial phonetic information sufficient to distinguish them from alternatives. In this study, infants in the second year also made use of word-initial information to understand fluent speech. The time course of comprehension was examined by tracking infants' eye movements as they looked at pictures in response to familiar spoken words, presented both as whole words in intact form and as partial words in which only the first 300 ms of the word was heard. In Experiment 1, 21-month-old infants (N = 32) recognized partial words as quickly and reliably as they recognized whole words; in Experiment 2, these findings were replicated with 18-month-old infants (N = 32). Combining the data from both experiments, efficiency in spoken word recognition was examined in relation to level of lexical development. Infants with more than 100 words in their productive vocabulary were more accurate in identifying familiar words than were infants with less than 60 words. Grouped by response speed, infants with faster mean reaction times were more accurate in word recognition and also had larger productive vocabularies than infants with slower response latencies. These results show that infants in the second year are capable of incremental speech processing even before entering the vocabulary spurt, and that lexical growth is associated with increased speed and efficiency in understanding spoken language. 相似文献

AbstractAlthough it is frequently claimed that learning analytics can improve self-evaluation and self-regulated learning by students, most learning analytics tools appear to have been developed as a response to existing data rather than with a clear pedagogical model. As a result there is little evidence of impact on learning. Even fewer learning analytics tools seem to be informed by an understanding of the social context and social practices within which they would be used. As a result, there is very little evidence that learning analytics tools are actually impacting on practice. This paper draws on research in self-regulated learning and in the social practices of learning and assessment to clarify a series of design issues which should be considered by those seeking to develop learning analytics tools which are intended to improve student self-evaluation and self-regulation. It presents a case study of how these design issues influenced the development of a particular tool: the Learning Companion. 相似文献

Collaboration networks have primarily been studied in developed economies. In this paper, we present a comprehensive analysis of co-inventor networks in a small but thriving OECD economy in Latin America: Chile. Using a dataset for patents granted in the country between 1989 and 2018, we study a variety of statistical properties for five different co-inventor networks. We show that these networks exhibit power-law, small-world, and preferential attachment properties, all of which have been used to describe networks in more advanced economies. We also highlight some apparent differences in collaboration patterns between networks (and inventors) and we reveal the precarious nature of the network of local inventors by confirming the community structure property. Evidence for strong positive autocorrelation between highly and lowly productive inventors is presented via methods used in spatial econometrics. Our results show that the inventor system in Chile is highly fragmented, which emphasizes the need for strong government intervention in steering research funding, and for more collaboration between inventors, especially local ones. 相似文献

In the laboratory, students can actively explore concepts and experience the nature of scientific research. We have devised a 5-wk laboratory project in our introductory college biology course whose aim was to improve understanding in five major concepts that are central to basic cellular, molecular biology, and genetics while teaching molecular biology techniques. The project was focused on the production of adenine in Saccharomyces cerevisiae and investigated the nature of mutant red colonies of this yeast. Students created red mutants from a wild-type strain, amplified the two genes capable of giving rise to the red phenotype, and then analyzed the nucleotide sequences. A quiz assessing student understanding in the five areas was given at the start and the end of the course. Analysis of the quiz showed significant improvement in each of the areas. These areas were taught in the laboratory and the classroom; therefore, students were surveyed to determine whether the laboratory played a role in their improved understanding of the five areas. Student survey data demonstrated that the laboratory did have an important role in their learning of the concepts. This project simulated steps in a research project and could be adapted for an advanced course in genetics. 相似文献

Globally, neoliberal education policy touts youth entrepreneurship education as a solution for staggering youth unemployment, a means to bolster economically depressed regions, and solution to the ill-defined changing marketplace. Many jurisdictions have emphasized a need for K-12 entrepreneurial education for the general population, and targeted to youth labeled ‘at risk’. The Martin Aboriginal Education Initiative’s Aboriginal Youth Entrepreneurship Program (AYEP) has been enacted across Canada. This paper applies critical discourse analysis to a corpus of texts, exposing how colonial practices, deficit discourse, and discursive neoliberalism are embedded and perpetuated though entrepreneurial education targeted at Aboriginal students via AYEP. 相似文献
