Conclusion In general terms the study indicates for the three schools examined the relationship between the academic grade of junior
secondary advanced science students and creative right hemispheric thinking is weak, but the relationship between the student's
grade and rational logical thinking is much stronger.
It may be that such relationships are a natural consequence of maturation and not related to the work done in the school.
Most educators would feel that the school system has some effect.
If each child is going to realise one's full thinking potential, it is important that the creative and holistic modes of thinking
be developed. In a future world which will be immersed in rapid change the need for this type of thinking is even more acute. 相似文献

The diurnal patterning of locomotion, stereotypy, grooming, eating, drinking, sleeping, postural readjustment, and inactivity was studied in 14 species of muroid rodents in the laboratory using a visual observation technique.Microtus canicaudus, M. montanus, M. ochrogaster, andM. pennsylvanicus exhibited acyclic activity patterns, whilePeromyscus eremicus,P. gossypinus, P. leucopus, P. maniculatus bairdi, P. polionotus, Calomys callosus, Mus musculus, andOnychomys leucogaster displayed nocturnality in their behavioral patterning.Rhabdomys pumilio exhibited crepuscular activities andNeofiber alleni displayed a complex pattern of nocturnality. Species differed in total amount of time spent per day for all activities but eating. The acyclicity ofMicrotus species appears to be related to high metabolic rates and a semifossorial life-style. 相似文献

The recent nationalDiscipline Review of Teacher Education in Mathematics and Science outlines the lack of confidence of many preservice primary school teachers in teaching science. This study explores the attitudes
of 170 primary school teachers in a Perth school district.
By means of a simple questionnaire the perceptions and attitudes of these teachers about the following aspects have been examined:
(1) background understanding of science; (2) preservice training; (3) interest in teaching science; (4) skill in teaching
science; (5) confidence in the plant, animal, matter, energy areas, and (6) time spent teaching science. Besides compiling
frequency responses for all teachers on these aspects comparisons have also been made on the basis of: (1) gender; (2) time
of graduation, and (3) grade level taught.
Specializations: Primary science, teacher attitudes.
Specializations: Primary science, science teaching strategies, curriculum implementation, cognitive studies. 相似文献

Background:Active videogames or exergames have been used as an innovative way to promote physical activity(PA)among various populations.A player’s interest in active videogames is associated with the fun and entertaining nature of the games and may trigger situational interest,thus increasing engagement.The goal of this study was to examine the impact of situational interest dimensions on college students’PA when playing the design-based bike exergame Greedy Rabbit(Vescape,Berlin,Germany).Methods:Sixty undergraduate students(age:20.8±1.3 years,mean±SD,18-25 years old;51.7%males)were recruited from the kinesiology department of a university located in the southern region of Belgium.The participants were assigned to an experimental group(n=41)or a control group(n=19)based on an incremental cycling test.Students in the experimental group engaged in 1 session of Greedy Rabbit(Vescape)while students in the control group engaged in 1 session of a placebo version of Greedy Rabbit(Vescape).The length of the sessions ranged from 24 min to 31 min.Results:Results for the control group indicated that the players’PA metrics(cadence:F(19,360)=1.43,p=0.11;heart rate:F(19.360)=1.16,p=0.29;oxygen consumption:F(19,360)=0.83,p=0.67)were stable during the exergame.Results for the experimental group demonstrated the effects of time on the players’PA metrics and revealed significant associations between the change in the players’situational interest dimensions and PA metrics(cadence:F(19,800)=26.30,p<0.01;heart rate:F(19,800)=19.77,p<0.01;oxygen consumption:F(19,800)=10.04,p<0.01).Conclusion:An approach using a design-based exergame may be a relevant strategy for promoting levels of PA that yields positive health-related outcomes among college students. 相似文献

AbstractIn solo offshore sailing races like those of the Solitaire du Figaro, sleep must be obtained in multiple short bouts to maintain competitive performance and safety. Little is known about the amount of sleep restriction experienced at sea and the effects that fatigue from sleep loss have on sailors’ performance. Therefore, we assessed sleep in sailors of yachts in the Figaro 2 Beneteau class during races and compared response times on a serial simple reaction-time test before and after races. Twelve men (professional sailors) recorded their sleep and measured their response times during one of the three single-handed races of 150, 300 and 350 nautical miles (nominally 24–50 h in duration). Total estimated sleep duration at sea indicated considerable sleep insufficiency. Response times were slower after races than before. The results suggest that professional sailors incur severe sleep loss and demonstrate marked performance impairment when competing in one- to two-day solo sailing races. Competitive performance could be improved by actively managing sleep during solo offshore sailing races. 相似文献
