ABSTRACTThis study was designed to explore what students perceive as essential factors influencing their sense of belonging. Gaining insight into what students perceive as influencing their sense of belonging enables design of interventions to foster that sense of belonging. Two hundred and nine students from a university in Sydney responded to the question: ‘What would help you to feel that you belong at Macquarie University?’ Results showed students most frequently identified people as instrumental in feeling that they belonged at university. Students also reported that places where there is respect, and where others are accepted, contributed to their feelings of belonging. Lastly, opportunities to interact with other students, such as within clubs, societies and at events, were reported by students to contribute to their feelings of belonging. Findings of the current study are discussed in relation to existing literature, to develop approaches that may enhance university students’ sense of belonging. 相似文献

Euro-American 2nd- and 4th-grade children (Ms=7.67 and 9.82 years) heard stories about Black and White characters who produced artwork yielding a windfall reward. Children allocated rewards to characters, justified their allocations, and judged the fairness of patterns representing different justice principles. Older children allocated more money to Black than White productive characters and to White than Black needy characters, consistent with predictions from aversive racism theory. Rationales most often relied on equality principles; older children gave more equity-based justifications for Black than for White characters. Fairness ratings of patterns representing 4 justice principles revealed effects for age and character race. Implications for understanding the developmental course of moral judgments as they apply to racial differences are discussed. 相似文献
