ABSTRACT

The quality of research depends greatly on access to existing information. Institutional repositories (IRs) have the potential to enhance and promote the dissemination of knowledge and research. This may lead to discoveries and innovation alongside maximizing return on investment in research and development. Following some background information, this article briefly discusses the processes involved in the establishment of Ghana's University for Development Studies (UDS) IR (UDSspace). Marketing and advocacy strategies employed to engage Faculty to enable them to contribute meaningfully and effectively in the populating of the IR are outlined and benefits described. The study uses a quantitative method. A questionnaire was used to elicit data from faculty. This article describes the various communication methods used to promote the IR and evaluates their effectiveness in getting users to participate in populating the IR. The survey found that although as high as 80.3% of respondents were aware of the benefits of an IR and 66.2% were aware of the existence of the UDS IR, 86.8% of respondents had not submitted to the IR.  相似文献

We designed an interrupted case study to teach aerobic cellular respiration to major and nonmajor biology students. The case is based loosely on a real-life incident of rotenone poisoning. It places students in the role of a coroner who must determine the cause of death of the victim. The case is presented to the students in four parts. Each part is followed by discussion questions that the students answer in small groups prior to a classwide discussion. Successive parts of the case provide additional clues to the mystery and help the students focus on the physiological processes involved in aerobic respiration. Students learn the information required to solve the mystery by reading the course textbook prior to class, listening to short lectures interspersed throughout the case, and discussing the case in small groups. The case ends with small group discussions in which the students are given the names and specific molecular targets of other poisons of aerobic respiration and asked to determine which process (i.e., glycolysis, citric acid cycle, or the electron transport chain) the toxin disrupts.  相似文献

Though there is little in the literature on the teaching of the history of English, criticism of textbooks which over-simplify the story as the rise of the standard variety has been more vocal of late. Meanwhile, some academics have argued for focusing teaching on the analysis of texts. This article reports on a unit/module taught at a British university that makes the analysis of texts central to teaching and assessment. It sets out to demonstrate what can be learned from approaching the subject in this way by presenting composite textual analyses created by the first-named author drawing on the work of his co-authors (five of his final-year undergraduate students). This was for two assignments, one focusing on an Early Modern English text and the other a more contemporary piece. A discussion highlights the benefits of making the analysis of texts central to the unit, and considers practical applications for teachers of the subject in other parts of the world.  相似文献

Students motivated to protect self‐worth perform poorly in situations that threaten to reveal low ability while performing well in situations that involve little threat to self‐worth. One factor contributing to their poor performance is thought to be their orientation towards social comparison goals (goals that have to do with vindicating their ability relative to others rather than pursuing mastery). In the present study, 96 undergraduate students who were either high or low in self‐worth protection were exposed to either success or failure feedback and subsequently primed to pursue either social comparison or mastery goals. For students high in self‐worth protection, the negative effects of either failure or social comparison goal priming is sufficient to give rise to poor performance. However, only when success is combined with mastery goal priming is a positive achievement outcome evident. The requirements of best practice approaches to encouraging students to adopt mastery‐orientated behaviours are discussed.  相似文献

The article takes the form of a letter written to pre-service or beginning teachers at the secondary level in the public school system. The letter acknowledges the attributes they bring to the profession (enthusiasm, optimism, creativity, and open-mindedness) and calls on them to make the most of and work to sustain these traits as they begin their careers. They are then advised in the importance of setting clear expectations for their students, maintaining high standards, and always demonstrating professionalism.  相似文献

This study tests the hypothesis that, during adolescence, antisocial behavior becomes positively associated with peer acceptance. This hypothesis was tested considering both classroom and out-of-class peer relations. Data from a previously published study, with a cross-sectional sample of 577 Italian 11- to 13-year-olds, were used. Analyses showed that in the 6th grade antisocial behavior was negatively related to classroom peer preference, but not significantly related to out-of-class peer inclusion. By the 8th grade, antisocial behavior was positively related to out-of-class peer inclusion, but not significantly related to classroom peer preference. Similar results were found for males and females. The higher level of peer acceptance among the 8th grade antisocial individuals was primarily due to nominations received by other antisocial individuals.  相似文献

Seventy-three deaf college students completed a survey examining perceptions about tutoring outcomes and emphases, characteristics of tutors, and responsibilities associated with learning through tutoring. The comparisons revealed that while baccalaureate and sub-baccalaureate students have many similar perceptions about tutoring, there are also some striking differences. In particular, as compared to the sub-baccalaureate students, baccalaureate students have a stronger preference for focusing on course content and for working with tutors who actively involve them during the tutoring sessions. In addition, baccalaureate students prefer to decide the focus of the tutoring themselves while sub-baccalaureate students tend to leave the decision to the tutor. The results of the analyses with three scales measuring perceptions of tutoring dimensions are summarized and recommendations for the selection and preparation of tutors, as well as for future research, are provided.  相似文献

Researchers examined how an inquiry-based instructional treatment emphasizing interrelated plant processes influenced 210 elementary pre-service teachers’ (PTs) conceptions of three plant processes, photosynthesis, cellular respiration, and transpiration, and the interrelated nature of these processes. The instructional treatment required PTs to predict the fate of a healthy plant in a sealed terrarium (Plant-in-a-Jar), justify their predictions, observe the plant over a 5-week period, and complete guided inquiry activities centered on one of the targeted plant processes each week. Data sources included PTs’ pre- and post-predictions with accompanying justifications, course artifacts such as weekly terrarium observations and science journal entries, and group models of the interrelated plant processes occurring within the sealed terraria. A subset of 33 volunteer PTs also completed interviews the week the Plant-in-a-Jar scenario was introduced and approximately 4 months after the instructional intervention ended. Pre- and post-predictions from all PTs as well as interview responses from the subgroup of PTs, were coded into categories based on key plant processes emphasized in the Next Generation Science Standards. Study findings revealed that PTs developed more accurate conceptions of plant processes and their interrelated nature as a result of the instructional intervention. Primary patterns of change in PTs’ plant process conceptions included development of more accurate conceptions of how water is used by plants, more accurate conceptions of photosynthesis features, and more accurate conceptions of photosynthesis and cellular respiration as transformative processes.  相似文献
