“Fear God; Fear the Bogaze”: The Nile Mouths and the Navigational Landscape of the Medieval Nile Delta,Egypt

By the fourth/tenth century, Egypt's Nile Delta had just two major Delta branches debouching directly into the Mediterranean – the Dumyā? (Damietta) and Rashīd (Rosetta). Navigational conditions at these branches’ mouths were treacherous because of a combination of currents, winds, wave-fields and shifting sandbanks. These conditions were a danger to shipping, and so had a formative effect on the navigational landscape of the Delta. Despite its remoteness from the Nile, Alexandria remained Egypt's chief Mediterranean port, but only because river connections were maintained that avoided the Rashīd mouth. In contrast, the port of Rashīd was relatively insignificant. Similar conditions at the Dumyā? mouth prompted navigators to adopt routes via Lake Tinnīs, modern Lake Manzala, which linked to the sea through its calmer sea mouths. This article brings together material from multiple disciplines to offer a new understanding of the navigational context of Egypt's medieval Mediterranean ports.     

Drawing Parallels in Search of Educational Equity: A Multicultural Education Delegation to China Looks Outside to See Within

In 2004, a professional delegation of multicultural educators visited the People's Republic of China to explore how diversity issues are addressed and how students are prepared for entry into the international workforce. The delegation, sponsored by the People to People Ambassador Programs, observed numerous parallels to the American system of education, including the challenge of providing equity for students of minority cultures, especially those in poor rural areas, and the conflict between modernization and preservation of cultural heritage.     

Education,age and skills: An analysis using PIAAC data

The main aim of this article is to analyse the change of adult skills, as captured by cognitive skills assessed in PIAAC, across age cohorts, taking into account that the quality of schooling may change from one cohort to another. We estimate a model that relates numeracy and literacy skills to age, schooling, gender and variables related to both family background and labour market performance. The specification allows us to control for changes in the efficiency of the transformation of schooling into skills when drawing age‐skill profiles. Our results show that the effect of ageing on skills, once isolated from cohort effects related to schooling, decreases monotonically across consecutive cohorts. The change of the efficiency of the transformation of schooling into both numeracy and literacy skills shows a remarkably similar pattern. Nonetheless, this change differs substantially between education levels, with the efficiency of the transformation of schooling into skills showing a steadier profile for intermediate than for higher education. Finally, empirical evidence is provided for the decomposition of the differences in the skill levels of the older vs. the prime age generations. The results suggest that the progressive expansion of schooling across younger generations partially offsets the negative effect of the irrepressible ageing of society on skills.

The Sum Is Greater Than the Parts: Deconstructing Homemade PowerPoint Games

Homemade PowerPoint games are a low-tech alternative for using game design in classrooms. To date, much of the research examining the games has not shown an improvement in performance. This has led some to question whether the games are properly aligned with the instructional strategies researchers have used as justifications to support using them. This study examined how increasing the structure of the game design project affected student performance when compared to control groups, as well as those who created games in previous iterations of the study. In addition, we examined the effects of student performance when two of the instructional strategies (microtheme writing and question writing) were tested in isolation. Most of the comparisons showed no statistical difference in performance; however, results from the final iteration yielded significant gains when compared to the control group.     

Pedagogic practices in the family socializing context and children's school achievement

This paper describes a qualitative study about pedagogic practices in the family. The pedagogic code underlying family practices is characterized and related to specific social groups. Students' achievement is discussed in relation to family and school pedagogic practices. The analysis of family pedagogic practice was based on a model derived from Bernstein's theory. The model considers two main dimensions, the coding orientation and its specific realizations in both the instructional and regulative contexts. It provided indicators of the family discursive context and the form in which knowledges and values are transmitted. The model developed allowed a deep and delicate analysis of the family socializing context. The study showed that families differ in their coding orientation and pedagogic practices, and suggested that there are factors other than social groups to determine family's pedagogic practice. It also suggested that specific familial practices may explain children's differential achievement at school.     

Diagrams and illustrations as aids to problem solving

The psychological literature relating to factors which should be taken into account in the design of illustrations and pictorial instructions as aids to problem solving is reviewed. The problem solver can invoke a wide range of strategies for using pictorial materials to achieve his goal, although pictorial instructions which indicate how to perform actions place a tighter constraint on the choice of strategy than illustrations showing only states to be attained. The designer must make his graphics compatible with as wide a range of strategies for using them as possible while building on the knowledge the problem solver already possesses.The author now works for the Post Office Telecommunications Systems Strategy Department, 88 Hills Road, Cambridge.     

Direct instruction in math word problems: students with learning disabilities

This investigation was conducted to test the effectiveness of strategy teaching and sequencing practice problems in teaching students with learning disabilities to identify the correct algorithm for solving addition and subtraction word problems. Sixty-two students were assigned to one of three experimental groups: strategy plus sequence, strategy only, and sequence only. The results indicated that students in the strategy-plus-sequence group, as well as those in the strategy-only group, scored significantly higher than did students in the sequence-only group. Findings indicated that strategy teaching was the more effective of the two instructional components. Implications are discussed in terms of instructional design for students with learning disabilities.     

A Grasshopperian Analysis of the Strategic Foul

The question of acceptability in respect to the strategic foul in sport has provoked a rich and seemingly irreconcilable dispute with normative theorists currently divided amongst three schools of thought including formalism, conventionalism and interpretivism. In this paper, I seek to transcend the three-way intellectual stalemate portrayed in the literature via a consideration as to whether or not the strategic foul qualifies as ‘Utopian’. More specifically, after demonstrating that Bernard Suits’ theory of game-playing is fully capable of embracing all three rival accounts, I seek to end the normative debate altogether via a conceptual analysis of the strategic foul as unacceptable via the higher-order point of view afforded by essentialism.
