Joint analysis of preschool attendance and school performance in the short and long-run

This paper aims at explaining the academic performance of a sample of children starting their first year at public schools in Montevideo, Uruguay, during 1999. We are mainly interested in the effect of pre-school education on the children's academic results. Previous probit and OLS estimations suggested that pre-school education has a positive impact on short and long term school performance. However, these results could be biased because a rather strong endogeinity of the pre-school education variable. We solved the problem by bivariate probit and treatment effects estimations. The results confirmed the bias and suggest that our previous estimations underestimated the positive effect of pre-school educations. Thus, we found fairly strong empirical evidence to suggest that having pre-school education has a short term positive effect on these children's results in the first year at school, and the long-term effect, after six years, seems to be somewhat weaker but is still positive. We also found several other factors connected with schools and with households that might lie behind children's short-term and long-term performance. It is important to note that, in the long-run, we found that a variable reflecting the general performance of the school had a strong effect on the academic performance after six year.     

Undergraduate Biotechnology Students’ Views of Science Communication

Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists’ public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi‐structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non‐scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.     

ARE STUDENTS PREPARED TO COMMUNICATE? A CASE STUDY OF AN AUSTRALIAN DEGREE COURSE IN BIOTECHNOLOGY

Public concerns about biotechnology have resulted in greater attention being paid to the mechanisms by which biotechnology is communicated with non-scientists, including the provision of science communication training. As undergraduate and postgraduate courses form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. Using an Australian biotechnology degree course as a case study, this paper examines science communication training within this course and the views of past and present students towards this training. Interviews were undertaken with 22 stakeholders in the case, including undergraduate lecturers (who also supervise postgraduate research students), doctoral candidates and biotechnologists recently graduated from the course. Few of the students felt the course provided them with any form of science communication training, let alone training in how to engage non-scientists. Many were unaware of the training available to them and few of the lecturers were able to identify where communication skills are taught within the course. A previous study of this case has also shown that biotechnology undergraduates taking this course do not value communication with non-scientists. Clearly, the current state of science communication training for these students needs to be improved if they are to enter the biotechnology workforce as able civic scientists. The findings of this study may be useful for other university biotechnology courses which have yet to integrate science communication training into their curriculum.     

Teaching to be American: the quest for integrating the Italian-American child

In the early years of the twentieth century, the great structural, social and cultural changes in American society included a growing number of immigrants arriving from the poorest regions of Europe. For the first time, the issues of immigration, assimilation and social integration became the most important problems facing American society. In the optimistic climate of the so-called progressive era, social reformers thought that these problems could be solved by the science of pedagogy, as applied to the educational needs of foreign immigrants. This essay centres on the pedagogical efforts of Italian-American educator Angelo Patri, who attempted to integrate Italian-American children into the fabric of American society through education. It starts by assessing Patri’s early writings, such as A Schoolmaster of the Great City, and his private and professional papers. In doing so, his work is situated in the debate on progressive education alongside pedagogue Maria Montessori, demonstrating his central role in the debate on integration through education. Within this analysis, particular attention is paid to the notion of learning by doing, and it is argued that both educators were influenced by this particular aspect of progressive education.     

Application of functional principal component analysis in race walking: An emerging methodology

This study considered the problem of identifying and evaluating the factors of individual performance during race walking. In particular, the study explored the use of functional principal component analysis (f-PCA), a multivariate data analysis, for assessing and classifying the kinematics and kinetics of the knee joint in competitive race walkers. Seven race walkers of international and national level participated to the study. An optoelectronic system and a force platform were used to capture three-dimensional kinematics and kinetics of lower limbs during the race walking cycle. Functional principal component analysis was applied bilaterally to the sagittal knee angle and net moment data, because knee joint motion is fundamental to race walking technique. Scatterplots of principal component scores provided evidence of athletes' technical differences and asymmetries even when traditional analysis (mean ± s curves) was not effective. Principal components provided indications for race walkers' classification and identified potentially important technical differences between higher and lower skilled athletes. Therefore, f-PCA might represent a future aid for the fine analysis of sports movements, if consistently applied to performance monitoring.     

Effect of Dental Course Cycle on Anatomical Knowledge and Dental Carving Ability of Dental Students

This study assessed the effect of the course cycle on theoretical knowledge of dental morphology and the dental carving ability of dental students. Thirty-two dental students from the third semester (initial cycle) and 30 students from the eighth and tenth semesters of the dental course (end cycle) had their theoretical knowledge on dental morphology assessed using a questionnaire with ten closed questions. Their dental carving ability was also assessed using wax carvings in macro models of plaster (for the third [S3] and eight [S8] semesters) and natural-sized artificial teeth (for the tenth [S10] semester). The teeth chosen for the dental carving activity were #16 and #47. The scores were statistically analyzed using the t-test, Kruskal–Wallis test, and Mann–Whitney test (α = 0.05). Students from the initial cycle presented better theoretical knowledge than the other groups did (P < 0.007). No significant differences in carving score were found between the initial and end cycles (P > 0.05), although S10 students obtained a higher score for teeth #16 and #47 (P < 0.05). Natural-sized artificial teeth received a higher evaluation score in dental carvings than the macro models (P < 0.001). Within the limits of this study, it was possible to conclude that students from the initial cycle (S3) presented higher theoretical knowledge, whereas no difference in carving ability was observed between the initial and end cycles. The tenth semester (S10) students performed dental carvings with better quality. Furthermore, carvings in natural-sized artificial teeth presented better quality compared with the macro models.
