The aim of the article is to investigate the level of job satisfaction among cataloger librarians in university libraries in Nigeria. Eighty-six catalogers from 29 university libraries in Nigeria participated in the survey. A questionnaire was used for data collection, which was e-mailed to catalogers. Overall, 86% of the catalogers surveyed were very or somewhat satisfied with their current job. The findings revealed that catalogers in university libraries in Nigeria are dissatisfied with dimensions such as roles and responsibilities, workplace culture, rewards (salaries/benefits), and professional development. On the other hand, they are satisfied with administration and supervision, performance evaluation, and opportunities.  相似文献

In this paper, three different statistical approaches were used to investigate short-term tracking of cardiorespiratory and performance-related physical fitness among adolescents. Data were obtained from the Oporto Growth, Health and Performance Study and comprised 1203 adolescents (549 girls) divided into two age cohorts (10–12 and 12–14 years) followed for three consecutive years, with annual assessment. Cardiorespiratory fitness was assessed with 1-mile run/walk test; 50-yard dash, standing long jump, handgrip, and shuttle run test were used to rate performance-related physical fitness. Tracking was expressed in three different ways: auto-correlations, multilevel modelling with crude and adjusted model (for biological maturation, body mass index, and physical activity), and Cohen’s Kappa (κ) computed in IBM SPSS 20.0, HLM 7.01 and Longitudinal Data Analysis software, respectively. Tracking of physical fitness components was (1) moderate-to-high when described by auto-correlations; (2) low-to-moderate when crude and adjusted models were used; and (3) low according to Cohen’s Kappa (κ). These results demonstrate that when describing tracking, different methods should be considered since they provide distinct and more comprehensive views about physical fitness stability patterns.  相似文献

Negative associations between physical activity (PA), physical fitness and multiple metabolic risk factors (MMRF) in youths from populations with low PA are reported. The persistence of this association in moderately-to highly active populations is not, however, well established. The aim of the present study was to investigate this association in a Brazilian city with high frequency of active youths. We assessed 122 subjects (9.9?±?1.3 years) from Muzambinho city. Body mass index, waist circumference, glycaemia, cholesterolaemia, systolic and diastolic blood pressures were measured. Maximal handgrip strength and one-mile walk/run test were used. Leisure time PA was assessed by interview. Poisson regression was used in the analysis. The model explained 11% of the total variance. Only relative muscular strength and one-mile walk/run were statistically significant (p?相似文献

Motivation and success in computer-science courses are influenced by the strength of students’ self-efficacy (SE) beliefs in their learning abilities. Students with weak SE may struggle to be successful in a computer-science course. This study investigated the factors that enhance or impede the computer self-efficacy (CSE) of computer-science students. Data collection involved a survey of 524 undergraduate computer-science students from 10 Thai universities. The survey measured four items of CSE, 13 items pertaining to the classroom learning environment (CLE), and 14 items related to information sources of SE. Results revealed that perceptions of a CLE with autonomy, meaningfulness, and involvement were positively associated with strong CSE. In addition, perceptions of social persuasions such as meaningful and encouraging feedback or judgment from influential people demonstrated a statistically positive relationship with CSE. Perceptions of vicarious experiences whereby students determine and compare their own abilities with observational experiences of role models also demonstrated a statistically positive relationship with CSE. Perceived physiological and affective states such as anxiety and stress demonstrated a negative influence CSE. Implications for practice relate to students’ perceptions of autonomous learning, the value of positive feedback, students’ input into learning content and activities, role models for students and observation of how peers perform tasks better or worse.  相似文献

We summarize the argumentative theory of reasoning, which claims that the main function of reasoning is to argue. In this theory, argumentation is seen as being essentially cooperative (people have to listen to others' arguments and be ready to change their mind) but with an adversarial dimension (their goal as argument producers is to convince). Consistent with this theory, the experimental literature shows that solitary reasoning is biased and lazy, whereas reasoning in group discussion produces good results, provided some conditions are met. We formulate recommendations for improving reasoning performance, mainly, to make people argue more and better by creating felicitous conditions for group discussion. We also make some suggestions for improving solitary reasoning, in particular to maximize students' exposure to arguments challenging their positions. Teaching people about the value of argumentation is likely to improve not only immediate reasoning performance but also long-term solitary reasoning skills.  相似文献

This study aims to analyse the effect of source credibility on students’ identification and assessment of comprehension obstacles in science texts. Source credibility was manipulated by providing 12th grade students with paragraphs supposedly taken from science textbooks or, alternatively, from students’ reports. The paragraphs contained information expected to be difficult to understand by the participating students. The students were instructed to report any comprehension obstacle they might find and to rate the comprehensibility of the paragraphs. There was no effect of source credibility on noticing and reporting comprehension obstacles in the conditions of our experiments. However, there was a significant finding regarding comprehensibility scores. The students rated the comprehensibility of the paragraphs supposedly taken from science textbooks higher than the comprehensibility of the same paragraphs supposedly taken from peer reports. The finding has implications on the way students approach the understanding of science texts. An enhancement of students’ feelings of competence in dealing with scientific subject matter would have a beneficial effect on students’ assessment and validation of information in science texts.  相似文献

Assessment in institutions of higher learning has been researched worldwide. However, there are gaps in research exploring the implications of assessment practices for learners’ access to the kind of knowledge enabling them to participate in their communities’ socio-economic transformation. This is the case in the African Great Lakes region, including Rwanda. This paper investigated the assessment practices at the University of Rwanda-College of Education to establish whether they enable students to access powerful knowledge for socio-economic transformation, which promotes critical thinking and creativity, or the knowledge of the powerful, which promotes memorization of knowledge produced by experts. The study adopted mixed methods, where 361 questions from 20 examinations papers for 2014/2015 and 2015/2016 academic years were analysed using Bloom’s revised taxonomy. Interviews with lecturers and group discussions with students were conducted. The findings revealed that assessment practices heavily encourage the knowledge of the powerful, with limited focus on the socio-economic transformative knowledge. Such practices are unlikely to lead to national socioeconomic transformation, which the government expects from education. The paper recommends revisiting assessment practices in Rwandan higher education to instil in the graduates the required knowledge for active contribution to socio-economic transformation.  相似文献

South African research on young children’s constructions of social identities illuminates the significance of play in the construction of gender identities. However, what remains largely understudied are the children’s construction of sexualities through play. The dominant discourse of ‘childhood innocence’ obscures the variegated understandings of the meanings children attach to sexualities. This paper will explore how some South African boys and girls aged 9–10 years construct themselves as active heterosexual subjects through football talk and play during break-time at school. The paper will demonstrate how the school playground is constructed by the ‘charmer boys’ as a ‘football space’ where they use football performance to impress and charm the ‘cream girls’ who are relegated to the margins as spectators of the football games. However, the paper will also argue that gender power relations are complex and that the position of the ‘creamers’ is infused with power as reflected in the role that they play as assessors of the boys’ performance.  相似文献

The accomplishment in mathematics has gained attention from educators and arises as an emerging field of study, including in engineering education. However, in Portugal, there is still incipient research in the area; so it is high time to explore factors that might enlighten the gap in the study of the relationship between Portuguese engineering students and the learning of mathematics. The main purpose of this study is to explore three factors identified in the literature as influencing the learning of mathematical concepts – self-efficacy, anxiety towards mathematics and perceived importance of mathematics – and search for differences by gender and by type of engineering course, a dimension not much reported in the literature but which was revealed as important in the team's previous research. Based on a sample of 140 undergraduate students of different engineering courses from University of Minho, results only identify differences in the type of course and not in gender. These results constitute a contribution and open new paths for future research in the engineering education.  相似文献
