Data from a survey of 2,431 students attending high schools in Hawaii indicated that students agreed with their parents’ wishes for post-high school occupation. Females tended to choose more academic post-high school destinations than males. An inverse relationship between academic high school curricula and post-high school academic goals was found, probably due to the fact that females were academically upwardly mobile. The need for financial assistance tended to decrease academic aspirations. It was concluded that knowledge of parental values, differences in academic aspirations between males and females, financial need, and a student’s high school curriculum would be valuable in helping students select post-high school destinations.  相似文献

Hungry rats were trained in a two-lever conditioning chamber to earn food reinforcement according to either a win–shift/lose–stay or a win–stay/lose–shift contingency. Performance on the two contingencies was similar when there was little delay between the initial, information part of the trial (i.e., win or lose) and the choice portion of the trial (i.e., stay or shift with respect to the lever presented in the information stage). However, when a delay between the information and choice portions of the trial was introduced, subjects experiencing the win–shift/lose–stay contingency performed worse than subjects experiencing the alternative contingency. In particular, the lose–stay rule was differentially negatively impacted relative to the other rules. This result is difficult for ecological or response interference accounts to explain.  相似文献

ABSTRACT

Although there is a substantial literature critical of the colonising discourses of higher education in both teaching and learning and research, there has been relatively little commentary about work integrated learning (WIL) from an Indigenous perspective. Currently, the higher education discourse of WIL is dominated by a teaching and learning perspective, which focuses almost entirely on the benefits to the student and/or the educational institution. This leaves the Indigenous community experience invisible and continues to reinforce a neo-colonial relationship between higher education providers and Indigenous people. This article reports the findings of a study undertaken in partnership with the Aboriginal community of Cherbourg in Queensland, Australia, which sought to understand the community experience of students undertaking WIL within Cherbourg. Twenty yarns, undertaken by a research assistant employed from the community, provided the basis for identifying key meanings and requirements of the community in their hosting of higher education students. The recent experience of students by the community was found to be positive with reciprocity, openness and practical benefit over time being central concerns. The study concludes that WIL with Indigenous agencies and communities requires decolonising, temporal and relational frames to be employed in the process of negotiating the purpose and processes of higher education student engagement.  相似文献

The Assessment Experience Questionnaire has been widely used to measure conditions of learning from assessment. It is one of three methods used in the ‘Transforming the Experience of Students through Assessment’ research process, originally funded by the Higher Education Academy to explore programme assessment patterns, and now used extensively in universities in the United Kingdom. Given the growth of assessment and feedback research over the last decade, the Assessment Experience Questionnaire is ripe for revision. Critics have queried its theoretical and statistical robustness. This study investigated the psychometric properties of the Assessment Experience Questionnaire, as the first step in the process of strengthening the instrument. Specifically, we examined the validity of the questionnaire with a sample of final year undergraduate students from eight UK universities (n?=?633). Results were mixed, confirming that the questionnaire has some value, but indicating that not all sub-scales possess adequate psychometric properties to underpin confident conclusions. As a result, we have embarked on a process of making conceptual modifications to the Assessment Experience Questionnaire, both to update the theoretical constructs, and to ensure stronger overall validity.  相似文献

We assessed relations between early temperament and behavior problems across 12 years in an unselected sample of over 800 children. Temperament measures were drawn from behavior ratings made by examiners who observed children at ages 3, 5, 7, and 9. Factor analyses revealed 3 dimensions at each age: Lack of Control, Approach, and Sluggishness . Temperament dimensions at ages 3 and 5 were correlated in theoretically coherent ways with behavior problems that were independently evaluated by parents and teachers at ages 9 and 11, and by parents at ages 13 and 15. Lack of Control was more strongly associated with later externalizing behavior problems than with internalizing problems; Approach was associated with fewer internalizing problems among boys; and Sluggishness was weakly associated with both anxiety and inattention, especially among girls. Lack of Control and Sluggishness were also associated with fewer adolescent competencies. These results suggest that early temperament may have predictive specificity for the development of later psychopathology.  相似文献

This study investigated the performance-related feasibility and physiological benefits of purposefully eliminating propulsive work while descending in mountain biking and compared values to those measured during road descending. Participants cycled uphill on a road at race pace before descending over three conditions (off-road pedalling; off-road coasting; road coasting). Relatively low power output during off-road pedalling was associated with a greater oxygen uptake (p?<?.01) when compared with off-road coasting despite no difference in vibration exposure (p?>?.05). Importantly, pedalling did not invoke a performance benefit (p?>?.05) on the descent used in this study. Significantly greater heart rate and oxygen uptake (both p?<?.01) were observed between road and off-road descending, likely caused by the increase in terrain-induced vibrations (p?<?.01) experienced between the bicycle and rider. Results indicate that reducing propulsive work during descending can improve recovery without being disadvantageous to performance. Similarly, the vibrations experienced during road descending are relatively low, and further reduce oxygen cost. In an effort to increase efficiency, it is recommended that mountain bike athletes focus on skills to increase descending speed without the addition of pedalling, and that equipment be used to decrease vibrations nearer to those seen on the road.  相似文献

In youth-focused community and citizen (YCCS) youth in classrooms and community-based programs produce data that scientists, resource managers and community members will use. This “nested” data situates learners’ scientific activity within larger datasets, projects, and communities, with consequences for youth agency. To document opportunities for agentive learning with data in YCCS, we report on how youth interact with data across eight school and community-based project sites and how youth talk about their data and work. From analysis of 54 participant interviews, we found that youth perceived the data they produced as being used for: (1) broader scientific work, (2) their own learning, and (3) community endeavors. Nested uses of data were most meaningful when youth interacted with end users, were exposed to the larger datasets to which they contributed, or took action linked to data. Not all youth saw, believed, or valued that data would be used by others. Framing of task and purpose, nature of engagement with community users, data production protocols, and level of emphasis on youth-identified questions may contribute to youth perceptions and can foster or undermine conditions for learner agency. The results shed light on when and how conditions for expansive learning and agency get established.  相似文献

Data from 561 high-school seniors were analyzed using multiple linear regression to determine the independent contribution of each variable to the criterion of rank in class (R). Significant F ratioswere obtained for SCAT V and Q, teachers’ ratings of Accuracy (ACCU), Effort and Industry (E-I), and Reliability and Responsibility (R-R). R-R and ACCU, but not E-I, were found to be significant preditors of SCAT V and SCAT Q. Females were significantly higher than males on R, ACCU, E-I, and R-R and lower on SCAT Q. The data were interpreted as supporting the effectiveness of teachers’ ratings in predicting academic performance in high school. Females’ superior performance on teacher ratings was interpreted as evidence that females conformed more than males to teachers’ expectations.  相似文献

Measuring the performance of a sports surface is typically derived from a series of field and laboratory tests that assess the playing properties under simulated game conditions. However, from a player’s perspective their own comfort and confidence in the surface and its playing characteristics are equally if not more important. To date no comparative study to measure playing preference tests has been made. The aim of this research was to develop a suitable method for eliciting player perceptions of field hockey pitches and determine the key themes that players consider when assessing field hockey pitches. To elicit meaningful unbiased human perceptions of a playing surface, an individual subjective analysis was carried out, using interviews and inductive analysis of the recorded player statements. A qualitative analysis of elite hockey players (n = 22) was performed to obtain their perceptions immediately after a competitive match. The significant surface characteristics that emerged as part of an inductive analysis of their responses were grouped together and formed five general themes or dimensions: player performance, playing environment, pitch properties, ball interaction and player interaction. Each dimension was formed from a hierarchy of sub-themes. During the analysis, relationships between the dimensions were identified and a structured relationship model was produced to highlight each relationship. Players’ responses suggested that they perceived differences between pitches and that the majority of players considered a ‘hard’ pitch with a ‘low’ ball bounce facilitating a ‘fast’ game speed was desirable. However, further research is required to understand the relative importance of each theme and to develop appropriate measurement strategies to quantify the relevant engineering properties of pitch materials.  相似文献
