Evolution and validation of a personal form of an instrument for assessing science laboratory classroom environments

The research reported in this article makes two distinctive contributions to the field of classroom environment research. First, because existing instruments are unsuitable for science laboratory classes, the Science Laboratory Environment Inventory (SLEI) was developed and validated. Second, a new Personal form of the SLEI (involving a student's perceptions of his or her own role within the class) was developed and validated in conjunction with the conventional Class form (involving a student's perceptions of the class as a whole), and its usefulness was investigated. The instrument was cross-nationally fieldtested with 5,447 students in 269 senior high school and university classes in six countries, and cross-validated with 1,594 senior high school students in 92 classes in Australia. Each SLEI scale exhibited satisfactory internal consistency reliability, discriminant validity, and factorial validity, and differentiated between the perceptions of students in different classes. A variety of applications with the new instrument furnished evidence about its usefulness and revealed that science laboratory classes are dominated by closed-ended activities; mean scores obtained on the Class form were consistently somewhat more favorable than on the corresponding Personal form; females generally held more favorable perceptions than males, but these differences were somewhat larger for the Personal form than the Class form; associations existed between attitudinal outcomes and laboratory environment dimensions; and the Class and Personal forms of the SLEI each accounted for unique variance in student outcomes which was independent of that accounted for by the other form.

Defining the family: towards a critical framework for families of children with disabilities

ABSTRACT

Family‐centred approaches are widely recognized internationally as the most ecologically appropriate way of working with families of children with disabilities. Pivotal in this approach is its focus upon the needs of the whole family, rather than only the needs of the child (with a disability). It places a significant emphasis on flexible and responsive transdisciplinary service delivery and upon parent choice and decision‐making. For the family‐centred approach to become truly effective, then, we must define what constitutes a family. Or rather ask families how they define themselves. Alongside an exploration of traditional and non‐traditional family roles, this paper challenges stereotypical notions of the family, and seeks to establish the family as the core element in any service team.     

GRADUATE TRAINING IN EDUCATION AND AGING: RESULTS OF A NATIONAL SURVEY; PART 1

The graduate departments of adult education at 88 universities in the United States were surveyed for information pertinent to their programs in and about aging. Results show that 55% of the departments offer no courses dealing exclusively with education and aging. Only one department offers a program concentration per se in educational gerontology. Those adult education academic programs that have a seeming interest in education and aging typically offer only an isolated course or two. Much needs to be done if adult education programs are to begin preparing people to meet the learning needs of older adults.     

The effects of mood,cognitive style,and cognitive ability on implicit learning

In an experiment with 109 undergraduates, we examined the effect of mood, cognitive style, and cognitive ability on implicit learning in the Artificial Grammar (AG) and Serial Reaction Time (SRT) tasks. Negative mood facilitated AG learning, but had no significant effect on SRT learning. Rational cognitive style predicted greater learning on both tasks, but this effect on SRT was mediated by cognitive ability. SRT, but not AG learning was significantly correlated with Math and English scores on the ACT. These findings confirm and contradict previous research. The association of negative mood and rational cognitive style with AG confirms that AG learning is facilitated by systematic, bottom-up processing. However, the lack of converging evidence for the SRT task suggests that the tasks involve different aspects of implicit processing. Theoretical explanations and suggestions for future research are discussed.     

A Card Trick for Improving Writing Skills and Attendance

This paper describes an innovative way of randomly collecting handwritten homework in calculus classes with approximately 50 students using a standard deck of cards, which does not place an excessive burden on faculty with regard to grading. In addition to the increased awareness students develop in structuring a mathematical solution, the strategy has been successful in increasing classroom attendance, which the literature suggests leads to increased attainment. Along with personal observations and empirical data indicating that the scores from the randomly collected homework assignments strongly correlate with exam performance, perceptions of students are included, which show that students are strongly supportive of the method used.     

The influence of pre-warming on the physiological responses to prolonged intermittent exercise

To examine the influence of pre-warming on the physiological responses to prolonged intermittent exercise in ambient temperatures of 21.5?±?0.6°C and relative humidities of 35.7?±?5.4% (mean?±?s), six healthy men performed intermittent treadmill running (30-s bouts at 90% of maximal oxygen uptake separated by 30-s static recovery periods) to exhaustion after active pre-warming, passive pre-warming and pre-exercise rest (control). Exercise time to exhaustion was significantly different between all conditions (active, 51.8?±?7.2?min; passive, 38.5?±?11.1?min; control, 72.0?±?17.2?min; P <?0.05). These changes in performance time were closely associated with a significant decline in both the rate of heat storage and heat storage capacity (P <?0.05). Rectal temperature, heart rate and ratings of perceived exertion were significantly higher during exercise in the two pre-warming conditions than in the control condition (P <?0.05). Ratings of perceived exertion were also significantly higher during exercise following passive pre-warming compared with active pre-warming (P <?0.05). During exercise there were no significant differences in serum prolactin, plasma norepinephrine and plasma free fatty acid concentrations between conditions. We conclude that both active and passive pre-warming promote a reduction in prolonged intermittent exercise capacity in environmental temperatures of 21°C compared with pre-exercise rest. These performance decrements were dependent upon the mode of pre-warming and closely reflected alterations in body heat content.
