The purpose of this case series was to explore whether adults who did not have the opportunity to acquire reading skills during childhood are able to do so rapidly if trained with an adequate literacy program. After 14 weeks of training with a new, optimized, literacy course based on cognitive research, six out of eight participants became able to read words they had never encountered, hence demonstrating that they were definitely engaged in decoding processes that allow autonomous reading. Moreover, they showed enhanced phonemic sensitivity and phonological memory. The latter finding implies that functional changes can take place rapidly outside the reading domain even when reading is acquired in adulthood. Thus, there is no major plasticity impediment preventing rapid eradication of illiteracy in adults. 相似文献

Despite the fact that textbooks are primarily directed at students, research has shown that teachers are heavily reliant and dependent on them. On the other hand, there is some empirical evidence that textbook presentation of science content may lack accuracy and strengthen some alternative conceptions on their users. Besides, it seems that textbooks are not always in agreement with the results of educational research, namely in regard to teaching approaches. Thus, the main objective of this paper is to analyse how 9th grade Portuguese physics textbooks deal with heat and temperature, in order to see whether or not they are adequate sources of information for students and teachers. Eleven 9th grade textbooks are analysed with regard to ideas included, correctness of concepts and arguments, global teaching approach, learning activities (nature, diversity, level of investigation, etc.). The results indicate that the majority of the textbooks are hardly consistent with modem perspectives for science education. 相似文献

For the last 10 years, online pre-service teacher distance education has increased significantly in Brazil. As a result, research on this educational modality has also increased, in particular, research investigating the different roles students and teachers play in these courses. The purpose of this paper is to analyze the role of digital technologies in two specific contexts: how teachers, tutors, and students play a role in producing interactive digital didactic material and how digital technologies themselves can play a role in teaching distance learning courses. But for these roles to emerge, we point to the need for participants of online courses to interact collaboratively. To identify these roles, grounded theory, a branch of qualitative research, was used as the two roles were articulated. Data were produced from virtual observations in virtual learning environments and virtual interviews. The results stress that both highlighted roles are related. They transform teacher and student roles and participation in the virtual classroom, and an “agency of media” emerges in online mathematics education. 相似文献

Objective
Paternity is uncertain, so if paternal feelings evolved to promote fitness, we might expect them to vary in response to variables indicative of paternity probability. We therefore hypothesized that the risk of lapses of paternal affection, including abusive assaults on children, will be exacerbated by cues of non-paternity.Methods
Cross-sectional study of 331 Brazilian mothers, interviewed about 1 focal child (age 1–12) residing with her and the putative father. Child physical abuse was assessed using the Conflict Tactic Scales: Parent Child (CTSPC). Two potential cues of (non) paternity were (1) whether the parents co-resided when the child was conceived, and (2) whether third parties allegedly commented on father–child resemblance. Data were analyzed through multiple logistic regressions.Results
Mothers reported child physical abuse by 15.9% (95% CI 4.6–27.1) of fathers who had not cohabited with them at conception, compared to 5.9% (95% CI 3.1–8.7) of those who had. The odds ratio for abuse by fathers who had not cohabited at conception in relation to those who had—adjusted for income, education, age, sex of child, whether child was first born, household size, time father spent with child, and alcohol abuse and drug use by father—was 4.3 (95% CI 1.4–13.8). Mothers reported abuse of 7.0% (95% CI 4.0–10.0) of children who purportedly resembled their fathers, versus 8.7% (95% CI 0.2–17.1) of those who did not.Conclusion
According to maternal reports, not having co-resided at conception quadrupled the chance of child physical abuse by currently co-residing Brazilian fathers. The reported prevalence of abuse was unrelated to reported allegations of father–child resemblance. 相似文献45.

This paper focuses on the issue of how engineering programmes demand and/or promote argumentative reasoning, which is a subsequent aspect of curricular development. This was the main objective of the project on which this paper reports. This is to say that the focus is on assessment as a way to establish to what extent argumentative reasoning is demanded and mobilised in teaching and learning processes. This aim was achieved using a sample of assignments developed in courses in different Bologna undergraduate programmes at the Engineering School at the University of Porto, during the first semester of the academic year 2009/2010. Whereas problem solving in engineering constitutes a structural element in the curricular organisation of the engineering programmes and is strongly related to argumentative skills, it was possible to conclude that students demonstrate and explain extensively, but do not argue, possibly because their teachers do not invite them to do so in assessment situations. 相似文献

Do previous sports experiences influence the effect of an enrichment programme in basketball skills?
The aim of this study was to examine the effect of an enrichment programme in motor, technical and tactical basketball skills, when accounting for the age of youth sport specialisation. Seventy-six college students (age: M = 20.4, SD = 1.9) were allocated according to three different paths: (i) non-structured (n = 14), (ii) early specialisation (n = 34), and (iii) late specialisation (n = 28), according to information previously provided by the participants about the quantity and type of sporting activities performed throughout their sporting careers. Then, the participants of each path were randomly distributed across control and experimental groups. Variables under study included agility, technical skills circuit, as well as tactical actions performed in a 4-on-4 full-court basketball game. The results indicated improvements in the early and late specialisation paths namely in the experimental training groups. However, the late specialisation path revealed larger benefits, in contrast with the non-structured path, which showed less sensitivity to the enrichment programme, mostly sustained in physical literacy and differential learning. Higher improvements were observed in agility, and also in reducing the number of unsuccessful actions performed during the game. Overall, this study provided evidence of how early sports experiences affect basketball skill acquisition and contribute to adapt to new contexts with motor and technical-tactical challenges. In addition, a path supported by late specialisation might present several advantages in sport performance achievement. 相似文献

Growth mixture modeling (GMM) is a useful statistical method for longitudinal studies because it includes features of both latent growth modeling (LGM) and finite mixture modeling. This Monte Carlo simulation study explored the impact of ignoring 3 types of time series processes (i.e., AR(1), MA(1), and ARMA(1,1)) in GMM and manipulated the separation of the latent classes, the strength of the time series process, and whether the errors conformed to the time series process in 1 or 2 latent classes. The results showed that omitting time series processes resulted in more serious bias in parameter estimation as the distance between classes increased. However, when the class distances were small, ignoring time series processes contributed to the selection of the correct number of classes. When the GMM models correctly specified the time series process, only models with an AR(1) time series process produced unbiased parameter estimates in most conditions. It was also found that among design factors manipulated, the distance between classes prominently affected the identification of the number of classes and parameter estimation. 相似文献

Between the 1980s and 2007, Portugal used to have one-stage (5-year period) initial teacher education (ITE) programs. In 2007 and consistent with the Bologna process guidelines, Portuguese teacher education moved toward a two-stage model, which includes a 3-year undergraduate program of subject matter that leads to a licenciatura (or bachelor) degree and a 3-year professional master in the teaching of a subject. The way that teacher educators perceive the ITE programs effects the education of prospective teachers and consequently the future of science education. This paper aims at analyzing how science teacher educators perceived the changes that took place in this formal way of educating junior school (7th–9th grades) and high school (10th–12th grades) science teachers in Portugal, due to the implementation of the Bologna guidelines. To attain the objectives of the study, 33 science teacher educators including science specialists and science education specialists answered an open-ended online questionnaire, which focused on the strengths and weaknesses of the pre- and post-Bologna ITE programs, the overall quality of teacher education and measures for improving ITE. The results indicate that science teacher educators were quite happy with all of the ITE models, but they expressed the belief that both the science and the teaching practice components should be strengthened in the post-Bologna masters in teaching. Meanwhile, changes were introduced in Portuguese educational laws, and they proved to be consistent with the opinions of the participants. However, the professional development of teacher educators along with evidence-based ITE programs seems to be necessary conditions for overcoming the challenges that teacher education is still facing in Portugal and worldwide. 相似文献
