Distinguishing Between Multicultural and Global Education: The Challenge of Conceptualizing and Addressing the Two Fields

This qualitative study examines how a group of social studies teachers working in a suburban middle school with a predominantly affluent and white student body conceptualize multicultural and global education. The data reveals that several of the teachers experienced difficulties conceptualizing multicultural and global education, used them interchangeably, and did not articulate their importance to their students. In addition to interviews with teachers, classroom observations were conducted to see how they addressed multicultural and global education in class. The outcomes of this study indicate that pre-service and in-service teacher education should pay attention to delineating the distinct purposes of multicultural and global education and how these concepts can be infused into a social studies curriculum.     

Persistence and withdrawal by students in a preservice science and mathematics teacher education course

At a time when recruitment into preservice teacher education courses in mathematics and science is difficult, one strategy to increase the number of graduates is to minimise the number of students who fail to complete their university courses. This study sought to determine factors which distinguish withdrawers from persisters in the first semester of a B.Ed course. Discriminant analysis was employed; a discriminant function employing seven factors resulted in correct classification in 81% of cases. Further analysis distinguishing between dropouts and transferees resulted in two discriminant functions with some common variables. Specializations: Science Education, Pedagogy.

Periodic water,interwater interval,and adjunctive behavior in a 24-hour multiresponse environment

To examine the generality of the interreward response effects shown by rats under periodic food delivery, we presented .10 ml of water at minimum interwater intervals that ranged from 8 to 512 sec. Use of a 24-h multiresponse environment allowed evaluation of interdrink responses with respect to their excessiveness, patterning, and functional relationship to the interwater interval. In contrast to the extensive activity-inducing effects of periodic food, the only major excitatory effect of periodic water was increased attention to the water source. Although there were a few bitonic and direct relationships between interwater interval and changes in responding, the great majority of functions were inverse or inconsistent. Further, unlike the increase in drinking under periodic food, total eating decreased under periodic water. The major similarity with food reward was the apparent separation of interreward behavior into three general classes of reward-appropriate foraging responses: area-restricted search after reward, more general search (and waiting), and focal search preceding the next reward delivery.     

Initial conditioned solutions of a second-order nonlinear conservative differential equation with a periodically varying coefficient

The exact solution of the equation

$\text{d}{}^2\text{x}\text{dt}{}^2\text{+dx+d′f(wt)x}{}^3\text{=0,}$

where d, d' and w are positive constants, and ?(wt) is a rectangular periodic function of time is discussed. The equation describes approximately the transversal movement of a particle in an alternating gradient accelerator. The exact solution is obtained in the form of a composite recurrent relation containing five particular solutions. Each of these solutions corresponds to a specific well-defined area of the phase plane of the initial conditions. The dynamical behaviour and the stability of the movement are examined analytically.     

The lack of representation of educational psychology and school psychology in introductory psychology textbooks

The first goal of this study was to look at the representation of educational and school psychology in introductory psychology textbooks. Research into the representation of other sub‐fields of psychology has been conducted but no research has looked specifically at educational or school psychology. The second goal was to compare the representation of educational and school psychology in introductory psychology textbooks to see if one or the other is receiving more coverage. Third, the textbooks with the most coverage were listed in order to aid educational and school psychologists teaching introductory psychology courses in selecting textbooks that adequately cover material from their sub‐fields. A total of 57 introductory psychology textbooks were content analyzed: 65% of the introductory psychology textbooks had educational psychology material and 65% had school psychology material. However, in the textbooks containing this material the educational and school psychology material made up only .29% and .19% of the textbooks’ total content.     

Assessing emergent literacy in preschool classrooms

Recent research on the literacy development of children during the preschool years has emphasized the notion of “emergent literacy,” according to authors Kontos (1986) and Teale and Sulzby (1986). According to this view, preschool children learn about reading and writing as they participate in a literate culture. Early social interactions involving print are crucial to children's reading and writing development, according to the Early Childhood and Literacy Development Committee (1986).

Energy expenditure in professional flat jockeys using doubly labelled water during the racing season: Implications for body weight management

To formulate individualized dietary strategies for jockeys, it is vital that energy requirements are quantified. We measured total energy expenditure (TEE) over two separate weeks in spring and summer using doubly labelled water in a group of male flat jockeys (n?=?8, 36.9?±?5.7 years, 164?±?8?cm, 54.6?±?2.5?kg). Total energy intake (TEI) was self-recorded, as were all riding and structured exercise activity. Mean daily TEE was 10.83 (±2.3) and 10.66 (±1.76) MJ, (p?=?.61) respectively. Self-reported TEI were 6.03 (±1.7) and 5.37 (±1.1) MJ (p?=?.40), respectively, and were significantly lower than TEE (p?=?.01). Mean race rides were 17 (±6) and 13 (±3; p?=?0.37) and horses ridden at morning exercise were 8 (±6) and 7 (±4; p?=?.77) respectively. Additional structured exercise was 76.25 (±95.1) and 52.5 (±80.9) min per week (p?=?.35), respectively. At the individual level, TEE was related to body mass and the level of non-racing physical activity, but not riding. Physical activity levels for TEE were 1.76 (±0.37) and 1.69 (±0.27; p?=?.59) and appear modest when compared with other athletes, and similar to age-matched non-athletes, suggesting that conventional sport-specific nutritional recommendations do not appear applicable. The large discrepancy between TEE and TEI suggests significant under reporting of dietary intake. These data now provide an appropriate framework from which to formulate jockey nutritional guidelines to promote the ability to achieve the daily weight target and improve athlete welfare.
