The current study investigated the associations between three maternal and paternal parenting styles, moral intelligence, academic self-efficacy and learning motivation in three serial mediation models. Omani adolescents enrolled in 7th to 11th grades (N = 296) responded to an online survey containing demographic items and scales measuring the variables noted above. Results of Path Analysis indicated that the three models had a good overall fit. In detail, the three paternal styles (authoritative, authoritarian and permissive) had direct associations with moral intelligence and indirect associations with learning motivation. However, only two maternal parenting styles (i.e., authoritative and authoritarian) correlated directly with learning motivation and these two styles did not associate with moral intelligence. All effects were in the hypothesized direction except the effect of authoritative maternal and paternal styles. Moral intelligence had a positive direct correlation with students’ academic self-efficacy and learning motivation. Moral intelligence also mediated the negative associations between three types of fathers’ parenting styles and students’ motivation. Academic self-efficacy had a positive association with students’ motivation. These findings provided useful insights about the various association between external factors (e.g., parenting styles), internal factors (i.e., moral intelligence and self-efficacy) and students’ motivation among adolescents in middle and high schools. 相似文献

Methods for assaying lysosomal diseases in dried blood samples are very useful today due to its several advantages related to the stability of samples, its transportation, handled and analysis, and its potential use for newborn screening compared to traditional methods in leucocytes samples. For this reason, it is important to validate these assays before being used in routine laboratory. Because of different in biological markers based on ethnicity, we aimed this study to validation a DBS-based fluorometric assay for measurement of α-l-Iduronidase activity for diagnosis of MPS I patients in Iran. DBS samples were collected from 15 MPS I patients and 60 healthy age matched subjects. Diagnostic value, biological variance and α-l-Iduronidase activity were determined. DBS α-l-Iduronidase activity was significantly higher in male subjects than in female group. Using a cut-off level of 1.08 µmol/spot 20 h, sensitivity and specificity were 100 and 98 %. The linearity of test was proved and we showed that within-run and between run precision were 5.6 and 14.66 %. Measurement of α-l-Iduronidase activity in DBS samples is an accurate test for diagnosis of MPS I and because of its rapid shipping and simplicity to keeping, DBS-based enzyme activity could be considered as a useful diagnostic tool in this disease. 相似文献

Scaffolding teachers to foster inclusive pedagogy and presence through collaborative action research
Teachers can be influential change agents in transforming their schools if they regularly reflect on their pedagogical practices, looking for improvements that will help all learners reach their full potential. However, in many sub-Saharan African countries, teachers seldom get an opportunity to collaboratively reflect on their practices. Action research, as an in-service professional development strategy, can be an ideal means of empowering teachers to collaboratively reflect on and improve their pedagogy to be more inclusive. Drawing from collaborative action research projects conducted by teachers in two primary schools in Zanzibar, Tanzania, this article explores the role of collaborative action research in developing the capacity of teachers to inform improvements in their pedagogical practices. The findings show how the participating teachers, with scaffolding influence from a critical friend (research facilitator), developed professionally along their zones of proximal development by promoting their pedagogical and research skills to enhance the presence, participation and achievement of all learners in their schools. Based on the findings, the article shows both the advantages and disadvantages of using collaborative action research in teacher professional development in the study context. The article also discusses the significance of organisational learning in in-service professional development in order to foster inclusive pedagogy through collaborative inquiry among teachers. 相似文献

In a microgrid (MG) topology, the secondary control is introduced to compensate for the voltage amplitude and frequency deviations, mainly caused by the inherent characteristics of the droop control strategy. This paper proposes an accurate approach to derive small signal models of the frequency and amplitude voltage at the point of common coupling (PCC) of a single-phase MG by analyzing the dynamics of the second-order generalized integrator-based frequency-locked loop (SOGI-FLL). The frequency estimate model is then introduced in the frequency restoration control loop, while the derived model of the amplitude estimate is introduced for the voltage restoration loop. Based on the obtained models, the MG stability analysis and proposed controllers’ parameters tuning are carried out. Also, this study includes the modeling and design of the synchronization control loop that enables a seamless transition from island mode to grid-connected mode operation. Simulation and practical experiments of a hierarchical control scheme, including traditional droop control and the proposed secondary control for two single-phase parallel inverters, are implemented to confirm the effectiveness and the robustness of the proposal under different operating conditions. The obtained results validate the proposed modeling approach to provide the expected transient response and disturbance rejection in the MG. 相似文献

This study attempts to identify the factors perceived to be important in choosing an Institution of Higher Learning （IHL） for distance learning. One thousand five hundred questionnaires were distributed to the first year students in the social sciences distance learning programs and 980 valid responses were received of Malaysian public university. The results show that the top three factors influencing their preferred institution are qualification recognition IHL, future career advancement, and personal satisfaction. The results of this study provide insights to the IHL, employers and academics on the nature and relative importance of the factors perceived important for adult learners in the selection of their preferred IHL. 相似文献

Internationalization of higher education is a concept that often is transformed into a set of activities that has a certain international dimension. This can be done more or less consciously. Issues such as development of skills and knowledge, creation of an international culture on campus and the involvement of an international dimension in all activities concern university management. These are issues university managers have to deal with. But it also opens up new opportunities. The broader issues of internationalization require a strong involvement of the academic leaders and of senior officers. This contribution describes how changes around us force universities to take action and introduce clear policies for internationalization of higher education, based on the needs institutions for higher engineering education should respond to. Special attention is given to a recent Swedish evaluation on the effects of student exchange. This study is compared with experience at Chalmers. 相似文献

The need for renewable and non-fossil fuels is now recognised by nations throughout the world. Consequently, an understanding of alternative energy is needed both in schools and in everyday life-long learning situations. This study developed a two-tier instrument to diagnose students' understanding and alternative conceptions about alternative energy in terms of: sources of alternative energy, greenhouse gas emission, as well as advantages, and disadvantages. Results obtained with Years 10 and 11 students (n?=?491) using the 12-item two-tier instrument (α?=?0.61) showed that students' understanding of alternative energy was low (M?=?7.03; SD?=?3.90). The 23 alternative conceptions about alternative energy sources that could be identified from the instrument are reported. The implications for teaching and learning about alternative energy and suggestions for further development and improvement of the instrument are presented. 相似文献

This study is part of a large-scale project focused on ‘Qatari students' Interest in, and Attitudes toward, Science’ (QIAS). QIAS aimed to gauge Qatari student attitudes toward science in grades 3–12, examine factors that impact these attitudes, and assess the relationship between student attitudes and prevailing modes of science teaching in Qatari schools. This report details the development and validation of the ‘Arabic-Speaking Students' Attitudes toward Science Survey’ (ASSASS), which was specifically developed for the purposes of the QIAS project. The theories of reasoned action and planned behavior (TRAPB) [Ajzen, I., & Fishbein, M. (2005). The influence of attitudes on behavior. In D. Albarracín, B. T. Johnson, & M. P. Zanna (Eds.), The handbook of attitudes (pp. 173–221). Mahwah, NJ: Erlbaum] guided the instrument development. Development and validation of the ASSASS proceeded in 3 phases. First, a 10-member expert panel examined an initial pool of 74 items, which were revised and consolidated into a 60-item version of the instrument. This version was piloted with 369 Qatari students from the target schools and grade levels. Analyses of pilot data resulted in a refined version of the ASSASS, which was administered to a national probability sample of 3027 participants representing all students enrolled in grades 3–12 in the various types of schools in Qatar. Of the latter, 1978 students completed the Arabic version of the instrument. Analyses supported a robust, 5-factor model for the instrument, which is consistent with the TRAPB framework. The factors were: Attitudes toward science and school science, unfavorable outlook on science, control beliefs about ability in science, behavioral beliefs about the consequences of engaging with science, and intentions to pursue science. 相似文献

Investigating pre-service teacher motivation across cultures using the Teachers’ Ten Statements Test
Robert M. Klassen Said Al-DhafriWanwisa Hannok Shea M. Betts 《Teaching and Teacher Education》2011,27(3):579-588
Motivations for choosing teaching as a career were investigated in 200 pre-service teachers from Canada and Oman. We used a novel structured qualitative approach and two theoretical models to analyze how pre-service teacher career-choice motivation varied according to cultural context. The results of the study showed that Canadian participants made more self-references, and expressed higher levels of individual-focused motivation and social utility value as career motivators than did Omani participants. Participants from Oman expressed greater endorsement of teaching as a fallback career and higher levels of socio-cultural influences than Canadian participants. Results extend teacher motivation “teacher motivation theory” by investigating socio-cultural influences. 相似文献
