University education,credentialism and social stratification among Palestinian Arabs in Israel

Few attention was devoted to the relative impact exerted by differential university access and credentialing patterns on the intrasocial stratification of subordinate groups. The paper investigates the issue among Palestinian Arabs in Israel, along religious, socioeconomic and gender lines, as well as in comparison to respective trends of the Jewish majority. Findings suggest that, while inequalities in access, retention and graduation rates at university level persist between Jews and Palestinian Arabs; for the latter, the combined effects of labor-market structure and regulative sectorial state policies, have determined considerably the relative impact of social group of origin on university enrollment, retention and graduation rates. The various implications of these findings are then discussed, urging further, and more elaborate, research into their socioeconomic and political consequences.     

The Effectiveness of Teaching Geometry to Enhance Mathematical Understanding in Children with Down Syndrome

ABSTRACT

It is widely known that people with Down syndrome have difficulties transitioning from a basic understanding of counting and cardinality to more advanced arithmetic skills. This is commonly addressed by resorting to the mechanical use of algorithms, which hinders the acquisition of mathematical concepts. For this reason some authors have recently proposed a shift in the focus of learning from arithmetic to more fertile fields, in terms of understanding. In this paper we claim geometry fits this profile, especially suited for initiating children with Down syndrome into mathematics. To support this we resort to historical, epistemological, and cognitive reasons: the work of Séguin and his intuition on the central role of geometry in the development of abstract thinking in the so-called idiot children, the ideas of René Thom about the role of continuum intuition in the emergence of conscious thinking, and finally the two strengths people with Down syndrome display: visual learning abilities and interest in abstract symbols. To support these ideas we present the main findings of qualitative research on elementary mathematics teaching to a group of seven children (3–8) with Down syndrome in Spain. The didactic method used, naturally enhance their naïve geometrical conceptions.     

Defending Constructivism in Science Education

After an impressive development throughout the last two decades, supported by a greatamount of research and innovation, science education seemed to be becoming a newscientific domain. This transformation of Science Education into a specific field of researchand knowledge is usually associated with the establishment of what has been called anemergent consensus about constructivist positions. However, some voices have begunto question these constructivist positions and therefore the idea of an advancementtowards a coherent body of knowledge in the field of science education. The goalof this work is to analyse some of the current criticisms of the so-called constructivistorientations and to study their implications for the development of science education asa coherent body of knowledge.     

Teacher training colleges in the rural areas of Angola

The Aid for the Development of the People by the People (ADPP), a non-governmental organization (NGO), in collaboration with Angola’s Ministry of Education, has set up a network of secondary schools to train teachers to work in primary schools in the rural areas of Angola. These schools, called Training Colleges for the Teachers of the Future (CTFs), are involved in training a new type of teacher. This article discusses this educational practice, the main aim of which is to train primary teachers to work in the rural areas where too few trained teachers are willing to be posted. The authors describe the measures taken to better meet the needs of the rural areas in terms of teachers who have been properly trained and are motivated to work in such an environment, and then go on to analyse the reasons underlying the success of the CTF programme, specifically the fundamental differences from the state-run teacher training colleges, the way this new practice forms part of the overall reform of the education system and its role in the Education for All (EFA) initiative, and the fight against poverty.

Tradutore,traditore: Can the aect code of ethics “speak” across cultures?

Conclusion Although many questions remain unanswered, these early translations of the AECT Code of Ethics will be available at the AECT Web site to ensure that access to the principles is offered in languages other than English. As they become available, more translations will be added to the English, Farsi, French, Mandarin Chinese, Portuguese, and Spanish versions. The translations will be saved as PDF files to retain the unique characters of each language. Additional translators with expertise in both educational technology and the targeted languages will be identified. Exploration of ways to encourage debate regarding the viability of the translations within diverse cultures continues. The ultimate hope is that collaboration among members of the professional ethics committee of AECT, the translators, and interested educators will result in the development of a Code of Ethics that “speaks” across cultures and establishes a meaningful guide to professional conduct around the world. Authors’ Note: This article expands on earlier work published in the (2002) Proceedings of the Annual Meeting of the Association for Educational Communications and Technology, edited by M, Simonson.     

The ingestion of a caffeinated energy drink improves jump performance and activity patterns in elite badminton players

The aim of this study was to investigate the effectiveness of a caffeine-containing energy drink to enhance physical and match performance in elite badminton players. Sixteen male and elite badminton players (25.4 ± 7.3 year; 71.8 ± 7.9 kg) participated in a double-blind, placebo-controlled and randomised experiment. On two different sessions, badminton players ingested 3 mg of caffeine per kg of body mass in the form of an energy drink or the same drink without caffeine (placebo). After 60 min, participants performed the following tests: handgrip maximal force production, smash jump without and with shuttlecock, squat jump, countermovement jump and the agility T-test. Later, a 45-min simulated badminton match was played. Players’ number of impacts and heart rate was measured during the match. The ingestion of the caffeinated energy drink increased squat jump height (34.5 ± 4.7 vs. 36.4 ± 4.3 cm; P < 0.05), squat jump peak power (P < 0.05), countermovement jump height (37.7 ± 4.5 vs. 39.5 ± 5.1 cm; P < 0.05) and countermovement jump peak power (P < 0.05). In addition, an increased number of total impacts was found during the badminton match (7395 ± 1594 vs. 7707 ± 2033 impacts; P < 0.05). In conclusion, the results show that the use of caffeine-containing energy drink may be an effective nutritional aid to increase jump performance and activity patterns during game in elite badminton players.     

Analysis of the distance covered by Brazilian professional futsal players during official matches

The purpose of this study was to measure and characterise the distances covered by Brazilian professional futsal players. The trajectories of 93 players during five matches were obtained using an automatic tracking method. The distances covered were analysed for different game conditions: over the entire game and during the times when the ball was out of play and in play separately. When the entire game was considered, the results showed that there was a reduction in the total distance covered per minute from the first [median ± IQR (interquartile range): 97.9 ± 16.2 m/min] to the second half (median = 90.3 m/min; IQR = 12.0), and when only the in-play time was considered (first half: 136.6 ± 17.2 m/min; second half: 129.2 ± 16.7 m/min). The percentage of distance covered in the standing and walking velocity range was higher in the second half than in the first when considering the entire game (30.8% and 28.0%, respectively) and during the in-play time (19.3% and 16.2%, respectively). In conclusion, this study verified that futsal players reduced the physical performance during the second half.     

Relations between parent-child acculturation differences and adjustment within immigrant Chinese families

The relations between parent and child acculturation and family and child adjustment were examined among 91 immigrant Chinese families in Canada with early adolescents (average age of 12). Acculturation was assessed in public (e.g., language use) and private (e.g., values) domains separately in Chinese and Canadian cultures. With one exception, interactions between parent and child acculturation in Canadian domains were unrelated to adjustment (conflict intensity, depressive feelings, and achievement motivation). Interactions in Chinese domains were more clearly associated with adjustment. Specifically, mother-child interactions in Chinese public domains and father-child interactions in the Chinese private domain predicted adjustment. In all interactions, when parents were strongly orientated toward Chinese culture, lower levels of Chinese orientation among children were associated with lower adjustment.
