Cultural analysis of mathematical content in teacher education: the case of Elementary Arithmetic Theorems

This paper deals with the competence of Cultural (epistemological, historical and anthropological) Analysis of the Content (CAC), which is important for teachers’ awareness and autonomy when dealing with educational choices in a changing cultural and institutional context. We report on an 18-hour intervention in a teacher education course at the undergraduate level attended by 12 participants during the fall of 2013. The goal of the intervention was to enhance participants’ CAC in the case of Elementary Arithmetic Theorems by using the rationality construct derived from Habermas’ work. Qualitative analyses of participants’ discussions showed how the construct was gradually appropriated by them and contributed to their CAC. Trends emerging from quantitative comparisons with previous implementations of the same course provided some evidence regarding the effects of the intervention on the quality of participants’ CAC performances at the end of the course. The method chosen for participants’ assessment and their cultural background will be discussed as conditions for the success of the intervention.     

Decreasing course content improves student comprehension of science and attitudes towards science in freshman biology

This study demonstrates a small, but significant, difference in prior understanding of basic biological concepts between students enrolled in majors' versus nonmajors' introductory biology courses. By the end of their respective courses, nonmajors demonstrated greater improvement in posttest scores than did majors. Furthermore, although initially students in the major course had a significantly more positive attitude towards science, especially in terms of personal comfort with science, by the end of the course this difference disappears. Following a semester of instruction, the attitudes of nonmajors generally improved, but student attitudes in the majors' classes declined in nearly all categories. We demonstrate a significant instructor effect in these results.     

Inter-letter spacing,inter-word spacing,and font with dyslexia-friendly features: testing text readability in people with and without dyslexia

Over the last years, several studies have suggested a possible link between dyslexia and deficits in low-level visual processing (e.g., excessive crowding). At the same time, specially designed “dyslexia-friendly” fonts appeared on the market. This class of fonts presents two main features: the particular graphic characteristics of the letterform designed to avoid confusion between similarly shaped letters, and wider inter-letter and inter-word spacing to limit crowding. The literature testing the efficacy of “dyslexia-friendly” fonts in improving reading accuracy and increasing reading speed is controversial. We evaluated the impact of letterform (with vs. without dyslexia-friendly graphic features), inter-letter spacing (standard vs. increased), and inter-word spacing (standard vs. increased) on reading accuracy and speed. Two groups of 64 children each, with and without dyslexia, read aloud 8 equivalent texts. The data collected failed to show any effect from the letterform. As regards spacing, the data showed that reading speed is impaired by an increase in inter-letter spacing not combined with an adequate increase in inter-word spacing.     

Fairness in education: The Italian university before and after the reform

In 2001 the Italian tertiary education system embarked in a broad process of reform. The main novelty brought by the reform was a reduction of the length of study to get a first level degree together with the introduction of a two-years, second level, master degree. This paper aims at studying the effects of the reform in terms of fairness. To this end, we first define fairness criteria following a well developed theory of equality of opportunity, we then discuss existing inequality measures consistent with these criteria, we show their relationship, and adapt them to the educational framework. We finally employ this set of measures to show the evolution of fairness in the access to university in Italy before and after the reform. Although not all fairness measures we estimated show a higher degree of fairness after the reform, the large majority does, suggesting a positive effect of the reform under a vast range of possible definitions of fairness.     

The Evolution of Teaching Instruments and Their Use Between 1800 and 1930

At the beginning of the nineteenth century, the core of a typical teaching collection was composed by apparatus, which were very similar to the ones proposed in the eighteenth century by ‘s Gravesande, Nollet, Desaguliers and others lecturer demonstrators and makers. Since 1820 circa, new didactic instruments were introduced. Most of them concerned the fast developing branches of physics such as wave optics, electromagnetisms and acoustics. Instrument makers (and many scientists as well) were extremely prolific in inventing new devices for better demonstrating all the laws of physics and for clearly visualizing all its phenomena. Therefore, around 1900 all the most important German, French and British makers proposed in their thick catalogues thousands of didactic apparatus. But were all these instrument really used? Probably not. Many of them were acquired by schools and universities because they were considered “status symbol” marking the importance and the completeness of a collection. Others were simply shown as “tri-dimensional” illustrations. For various reasons, during the first decade of the twentieth century the number of available didactic instruments was drastically reduced. The introduction of student training laboratory, the increasing cost of labour and of materials after WWI, the needs of a more standardized production, the progresses of physics not only eliminated from the trade catalogues many of the classical but old fashioned instruments but also stimulated the use of modular and simpler didactic apparatus.     

The Media as a Policy Instrument in Influencing the Business Model of Professional Soccer: Evidence From Italy

Italian soccer clubs in the first division have individually sold broadcasting rights for their home matches, until new laws imposed pooling and joint-selling those rights through the league and established a mandatory sharing rule to redistribute revenues in order to improve on-the-pitch competitive balance (CB). This article compares the two institutional designs. While reducing revenue inequality, the new regime distorts allocative efficiency and informational rent appropriation, opens up costly ex post renegotiations and antitrust litigations, and does not improve CB.     

A pilot project of a cancer patient library in Italy: results of a customer-satisfaction survey and its products

AIMS: The purpose of this study is to determine the degree of satisfaction of users of the Cancer Information Point section of the Library for Patients (CIP-LP), active since 1998 at the National Cancer Institute of Aviano, Italy. The CIP-LP is based on a skilled intermediary, adequate informative material and a specific location, within the Scientific Library of the Institute. PATIENTS AND METHODS: A survey was developed to assess service functionality and quality from the users' viewpoint. During a 6-month period, a questionnaire was mailed to 194 patients and relatives who previously used the CIP-LP; 113 (58%) were returned and processed. RESULTS: Of the respondents, 91% were pleased with the CIP-LP and 95% would recommend the service to other people. The information obtained contributed to a clearer understanding of the illness and treatment (45% as first answer) and a better control of the situation (33%). Fifty-one per cent evaluated the information received as 'good', 42%'excellent' and 4%'of sufficient quality'. CONCLUSION: This survey shows the appreciation and usefulness in the users' perception of a specific hospital library for cancer patients and their relatives, providing an information service supplementary to doctor-patient communication.
