Rats were exposed twice in a rotated sequence to a series of six mazes, consisting of hexagonal alleys, balanced for different alley length and structural complexity. Locomotor activity increased with alley length and decreased with structural complexity of the mazes. Locomotion became less stereotyped with increased experience, showing an increasing number of turns, less constant velocity, loss of the initial preference for outward leading alleys and weakening of the forward tendency at reentry from side alleys into hexagonal alleys. In contrast to these qualitative changes of locomotion, the amount of activity remained almost unchanged throughout the experiment. The results suggest that these increases in locomotion complexity depend upon complex interactions between experience and stimulus content of the mazes. 相似文献

This paper outlines the design of a physics textbook that addresses issues of gender-inclusive physics teaching, STS and constructivism.
Difficulties of addressing these issues in a textbook for normal classes, which has to compete with other textbooks on the
market will be discussed.

The purpose of the study was to examine whether students’ linguistic skills and task-avoidant behavior (i.e., the child-related factors) and the mean level of academic skills (reading comprehension and math) of classmates (i.e., the class-related factor) are associated with teacher judgments of children’s reading comprehension and math skills. The participants were third-grade Estonian-speaking students (n?=?656; age 9?11 years) and their classroom teachers (n?=?51). The results of the structural equation modeling path analyses indicated that teachers tend to judge students showing higher academic and linguistic skills and lower avoidance behavior as higher on the reading comprehension and math skills. In contrast, the classmates’ higher academic skill level was related to lower judgments of individual children’s reading comprehension and math skills by teachers. 相似文献

Teachers’ capacity to learn intentionally and responsively in the classroom is particularly vulnerable during the first years in the profession. This study investigated the interrelations between early career teachers’ turnover intentions, perceived inadequacy in teacher–student interaction, and sense of professional agency in the classroom. The survey data were collected from 284 in-service teachers with not more than 5 years of experience and analysed by structural equation modelling (SEM). The results showed that the negative relation between turnover intentions and early career teachers’ sense of professional agency was completely mediated by perceived inadequacy in teacher–student interaction. The results indicate that experiences of insufficient abilities to solve pedagogically and socially challenging student situations have a crucial effect on early career teacher’s capacity for adaptive reflection and active transformation of instruction. 相似文献

The purpose of the study was to assess adolescents’ participation in various socio-digital activities by using a self-report questionnaire, a social networking questionnaire, and interviews. The participants (n?=?253) were grade 6–9 students from a multicultural lower-secondary school in Finland. Three profiles of socio-digital participation were identified: friendship oriented basic participators (n?=?161), gaming-oriented participators (n?=?61), and creative participators (n?=?31) intensively engaged in diverse socio-digital practices. The analyses revealed systematic differences in social networking relations as a function of adolescents’ social-digital participation profile and gender. The reciprocal values in hanging out, liking, and media multiplexity were highest for creative participators, whereas gaming-oriented participators were less socially active than their peers. The socio-digital expertise of creative participators was socially recognized by a larger group of peers than that of the other groups. The study produces methodological tools suitable for collecting systematic longitudinal data of socio-digital practices of larger groups of adolescents in future. 相似文献

This article examines the traditional assumption that higher education evaluation systems follow a similar global format. Comparative study examines institutional evaluation and assessment processes in two nation‐states that are geographically and economically remote but which, historically, share a common civic perspective. The main research question of the study is: What are the similarities and differences in the social functions of evaluation and assessment between these two countries, the models of evaluation of which originate from the same “homogeneous model of institutional evaluation”? The study demonstrates that Finnish and Argentine models of evaluation are nationally and contextually bound by general ideas rather than being applications of a global model. 相似文献

Who borrows laptop computers in an academic health sciences library? Why do they choose to check out laptops? In a survey, laptop computer users responded that the laptops were used most frequently to do class-related work. Laptops were most often checked out because they could be taken to a quiet area of the library or to where the user had more room to work. The majority of such borrowers were satisfied or very satisfied with the laptops and the service from the library. The majority of those completing the survey were medical school students and graduate students. The circulation of laptop computers at this academic health sciences library is a very successful and popular program. 相似文献
