Evidencing student achievement of standards is a growing imperative worldwide. Key stakeholders (including current and prospective students, government, regulators and employers) want confidence that threshold learning standards in an accounting degree have been assured. Australia’s new higher education regulatory environment requires that student achievements are benchmarked against intended programme learning outcomes, guided by published disciplinary standards and a national qualifications framework, and against other higher education providers. Here, we report on a process involving academics from 10 universities, aided by professional practitioners, to establish and equip assessors to reliably assure threshold learning standards in accounting that are nationally comparable. Importantly, we are learning more about how standards are interpreted. Based on the premise that meaning is constructed from tacit experiences, social interactions and intentional reflection on explicit information, we report outcomes of three multi-part calibration interventions, situated around judgements of the quality of the written communication skills exhibited in student work and their related assessment tasks. Qualitative data from 30 participants in the calibration process suggest that they perceive that the process both assists them both in developing a shared understanding of the accounting threshold learning standards and in the redesign of assessment tasks to more validly assess the threshold learning standards.  相似文献

A spacecraft formation flying controller is designed using a sliding mode control scheme with the adaptive gain and neural networks. Six-degree-of-freedom spacecraft nonlinear dynamic model is considered, and a leader–follower approach is adopted for efficient spacecraft formation flying. Uncertainties and external disturbances have effects on controlling the relative position and attitude of the spacecrafts in the formation. The main benefit of the sliding mode control is the robust stability of the closed-loop system. To improve the performance of the sliding mode control, an adaptive controller based on neural networks is used to compensate for the effects of the modeling error, external disturbance, and nonlinearities. The stability analysis of the closed-loop system is performed using the Lyapunov stability theorem. A spacecraft model with 12 thrusts as actuators is considered for controlling the relative position and attitude of the follower spacecraft. Numerical simulation results are presented to show the effectiveness of the proposed controller.  相似文献

The current study examines the association between parental support and adolescent sleep under varying levels of family stress. Participants included 316 adolescents (Mage = 16.40 years, 43% male) and their parents (Mage = 45.67 years, 91% mothers) from diverse ethnic backgrounds. Both adolescents and parents completed questionnaires and adolescents wore wrist actigraphs and completed self‐reports on their sleep for 7 consecutive days. Results indicated that under contexts of family stress, more parental support was linked to longer sleep duration, less sleep variability, and less time spent awake during the night. Findings suggest that under contexts of family stress, cohesive family relationships may provide a sense of stability and security that is necessary for healthful sleep.  相似文献

The role of spelling recognition was examined in word reading skills and reading comprehension for dyslexic and nondyslexic children. Dyslexic and nondyslexic children were matched on their raw word reading proficiency. Relationships between spelling recognition and the following were examined for both groups of children: verbal ability, working memory, phonological measures, rapid naming, word reading, and reading comprehension. Children’s performance in spelling recognition was significantly associated with their skills in word reading and reading comprehension regardless of their reading disability status. Furthermore, spelling recognition contributed significant variance to reading comprehension for both dyslexic and nondyslexic children after the effects of phonological awareness, rapid naming, and word reading proficiency had been accounted for. The results support the role of spelling recognition in reading development for both groups of children and they are discussed using a componential reading fluency framework.  相似文献

In this paper, we identify beliefs about teaching and patterns of instruction valued and emphasized by science, technology, engineering, and mathematics faculty in higher education in the USA. Drawing on the notion that effective teaching is student-centered rather than teacher-centered and must include a balance of knowledge-, learner-, community-, and assessment-centered learning environments; we use qualitative interview data to explore how faculty's reported beliefs about teaching are associated with their consideration of these four types of environments. Findings indicated that although a range of beliefs about teaching emerged, most were firmly located in knowledge-centered learning environments, with little or no focus on the remaining three learning environments. Furthermore, even patterns of instruction that were heavily student-centered were situated within a knowledge-centered learning framework. We argue that for student-centered instruction to be truly successful, faculty must consider all four learning environments in crafting and facilitating the classroom environment.  相似文献

Cognitive challenges during transition to adulthood are generally high and require particular skills, such as self‐control, performance evaluation, and behavioral adjustment for success in everyday living. However, age and sex differences in timing and efficiency of brain maturational processes in the early twenties are not well known. We used a go/no‐go paradigm and fMRI to focus on the neural processes underlying response inhibition and performance monitoring during the transition from late adolescence (aged 18–19) to young adulthood (aged 23–25). During performance monitoring, late adolescents showed more activation in right inferior frontal gyrus than young adults, while males showed more activation in left inferior parietal lobe than females. No effects of age and sex were found for response inhibition. Our findings suggest that age and sex‐related differences in neural basis of performance monitoring continue to change between late adolescence and young adulthood.  相似文献

The vast international literature on the effects of different types of ability grouping on self‐concept and pupils' attitudes towards school has focused on pupils from single year groups. This article aimed to explore year group differences in pupils' self‐concept and attitudes towards school as influenced by ability grouping. The study was cross‐sectional in design and measured attitudes towards school and mathematics, general and school self‐concept and preferences for different kinds of grouping in 234 pupils from years 7 through 10 attending a mixed comprehensive school. The findings indicated that mathematics self‐concept was consistently lower than school and general self‐concept; all aspects of self‐concept increased up to Year 9 and then declined in Year 10, pupils in the higher sets tended to have higher self‐concepts; pupil preferences for setting were greater in the higher year groups, as was the extent to which the top set was perceived to be the best. A substantial proportion of pupils wanted to move set, usually to a higher set. Set placement itself did not appear to have a consistent effect on attitudes towards mathematics. This seemed to be mediated by the quality of teaching.  相似文献

This study aimed to untangle the mixed effects of language brokering by examining a contextual factor (i.e., parent–child alienation) and a personal attribute (i.e., resilience) that may relate to adolescents’ feelings during translating (i.e., sense of burden and efficacy) and that may moderate the association between such feelings and adolescent depressive symptoms. Participants included 557 adolescent language brokers (Mage = 12.96) in Mexican‐American families. Results showed that adolescents with a strong sense of alienation from parents or low resilience (a) experienced more burden or less efficacy in translating and (b) were more susceptible to the detrimental effects of feeling a sense of burden and the beneficial effects of experiencing a sense of efficacy, as measured by depressive symptoms.  相似文献

Although sport management researchers concur with one another regarding the significance of interaction between employees and consumers in shaping the consumers’ attitudes and behaviors, the vast majority of previous studies are largely isolated such that they take assessment exclusively from one side of the dyad—either employees or consumers. The authors seek to advance the current body of knowledge by utilizing a dyadic method that includes judgments provided by employees as well as one of each employee’s consumers in a high-contact sport service context (i.e., multi-purpose fitness centers). As such, the authors investigate how employee citizenship behavior and deviance behavior influence consumer citizenship behavior and participative behavior through consumers’ perceived service quality and satisfaction with employees. The results indicated that employee citizenship behavior positively and deviance behavior negatively shaped consumers’ perceptions of service quality, whereas the negative moderating effect of employee deviance behavior between employee citizenship behavior and service quality was not supported. Satisfaction with employees significantly mediated the relationship between service quality and consumer citizenship behavior but not between service quality and consumer participative behavior. Theoretical, methodological, and practical implications derived from this study are discussed.  相似文献
