This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?P?P?相似文献
This study examined the effect of graphic representation of algebraic functions on performance of tasks involving expressions' transformations. Twenty eight teachers, who received instruction and practice using multiple representation software, were tested on their ability to debug faulty transformed expressions, either with or without graphic feedback. Two main strategies were used while debugging — Syntactic Manipulation (SYM) and Semantic Interpretation (SEI). It was found that subjects who used the SEI strategy, improved their performance while using graphs, as compared to no use of graphs. Some positive effect of the graphic feedback was also manifested for those using the SYM strategy, who were assisted by the graphs but continued to syntactically manipulate the expressions. All subjects improved their performance after the treatment, as measured by paper-and-pencil traditional tasks. 相似文献
The introduced study represents methodology and results of research focused on utilization of interactive whiteboard as didactic technology mediating information through multimedia worksheets applied in education process in pre-primary education. Its aim was to determine whether it can significantly increase the level of children’s acquired knowledge in the field of technical skills education and whether it can positively influence the development of children’s creative skills as a sign of their motivation. We observe that this issue in the way it is theoretically and practically established in this study can contribute by proposing education standards and set of multimedia worksheets in the technical field in Slovak pre-primary education. 相似文献
Elderly people are exposed to information technologies to keep them in touch with younger generations. Among various technologies, social network sites (SNSs) are seldom used by the majority of elderly people. To bridge the digital divide, it is necessary to dig deeply into the minority elderly users of SNSs. This study explores usage patterns of elderly Facebook users and further investigates how their diverse characteristics influence their usage and social circles. Three findings were derived. First, a sharp digital divide on SNSs does exist, and existing elderly Facebook users are mainly the dabblers. Second, personality profiling could predict elderly people’s SNS usage behaviors. Elderly users with a high level of openness and extroversion have more friends, status updates, and group memberships, and those with a high level of conscientiousness have fewer likes and status updates. Elderly users are likely to seek insightful content on SNSs. Moreover, they may have a higher degree of emotional stability than young users when using SNSs. Third, elderly people tend to build small social circles on SNSs that “copy” the family relationship in the real world; whereas, they build large social circles with interests and hobbies that are difficult to share in the real world. Based on these results, detailed suggestions are presented for better targeting elderly people in ways that move them toward SNSs. 相似文献
Purpose: This study attempts to close the research gap created by the fact that existing studies neglect the problem of how effectively agricultural professors from different European countries communicate. The aim is to identify similarities and differences in the numbers of agricultural professors perceived by students as engaging in verbal and nonverbal immediacy communication.
Methodology: An online survey was conducted among students of agricultural universities from Austria, Slovenia and Albania.
Findings: The results show that professors of agriculture from Austria, Slovenia and Albania should generally not be satisfied with their own communication patterns and should thus try to improve their communication. The result also reveals cultural differences in the shares of agriculture professors employing different communication patterns in Austria, Slovenia and Albania. Compared to Austrian and Slovenian students, their Albanian peers perceive that most of their professors use nonverbal immediacy communication. According to Austrian students, the majority of their professors use verbal immediacy. On the contrary, Albanian students assessed that some of their professors employ verbal immediacy.
Practical Implications: The results show the professors of agriculture should improve the way they communicate to students. In particular, the Albanian professors should improve their verbal communication especially in terms of providing timely and quality feedback to students.
Theoretical implications: The study reveals differences in immediacy communication among countries (Austria, Slovenia and Albania) which the scientific literature considers to have a high-context culture.
Originality/Value: Given that no study has yet examined how students perceive professors’ communication in different European countries, this research helps understand the characteristics of agricultural professors’ communication. 相似文献
This study explores the role of the motivational self-regulation in academic procrastination under the personality framework. Therefore, the aims of the study were to investigate: (a) the role of personality dimensions in the self-regulation of motivation; (b) the role of self-regulation of motivation in procrastination; and (c) the mediating role of the self-regulation of motivation. The participants were 274 university students (M?=?21 years). The Big Five traits explained from 6% to 17% variance of the individual motivational regulation strategies (MRSs). Both personality (conscientiousness) and the MRS (environmental control) were significant predictors of academic procrastination. Conscientiousness, agreeableness, and intellect showed an indirect effect on reducing academic procrastination, mediated through the strategy of environmental control, thus additionally suggesting the important role of this motivational strategy. Since this strategy can be taught, these findings have a strong practical value. 相似文献
The present study reports an empirical investigation into concept formation of young children. Based on interviews conducted before and after participating in a playfully enacted chemistry lesson at a culture center, it is analyzed how 6-year-old children conceptualize water, molecule, and chemistry. Theoretically, the study is informed by Vygotsky’s cultural-historical perspective on concept formation. The empirical data consist of pre- and post-interviews with children and documentation of their participation in the intermediate activity. This documentation is used in the post-interviews as a mutual ground for talking with the children about what they remember and how they understand the activity they participated in and what the activity intended to illustrate. The results are presented in terms of three inductively generated categories: ‘everyday’, ‘experientially-based’, and ‘generalized experiences’ concepts, respectively. The implications of these findings for early childhood chemistry (science) education are discussed.
The paper seeks to understand the trajectories of students who defer entry to university. The study was conducted in Lithuania, a former Soviet Union republic. The phenomenon of a ‘gap year’ is usually associated with young people, who decide not to enter higher education schools immediately after receiving secondary education, instead they choose to spend a year volunteering, working or engaging in other activities. This article analyses the choice of taking a gap year from the perspective of rational choice theory, complemented by human development theory, which was developed by R. Inglehart and his colleagues. The latter theory allows discovering relation between the spreading of the gap year phenomenon in developed European countries and the emergence as well as development of post-materialist values from the macro-level perspective. The theoretical analysis is based on semi-structured interview data collected in Lithuania. 相似文献
The aim of this qualitative study is to describe teachers’ perceptions and roles in prayer education in TALI day schools in Israel, using in-depth oral Interviews, written questionnaires and written materials of the schools’ network. Two educational ideologies were identified: Belonging to the Jewish collective and Personal-spiritual ideology. While participants perceive the aim of Jewish education as enhancing students’ belonging to the Jewish collective, prayer education introduces a personal-spiritual aspect that was not typically a part of teachers’ discourse on Jewish education. 相似文献
