Academic libraries are one of the most important sources of “on the job” training for future library instructors. Librarians who supervise and assess these future library instructors (often in graduate assistant positions) often choose to provide observations and feedback each semester to these instructors in training. Scholarly literature, however, provides little information on whether this system helps graduate assistants to develop as teachers. The authors of this article assessed graduate assistants’ performance as teachers over three semesters using a system of observation and self-assessment. They analyzed both patterns and areas of growth and discuss the strengths and weaknesses of this system. 相似文献

Rats were trained in a three-alternative spatial delayed matching-to-sample task in a starburst maze. Samples consisted of rewarded forced choices of one arm, and retention was indicated by rats’ returning to that arm after a 90-sec delay. If a rat made an error on its first choice, it was returned to the start compartment and allowed a second choice. Unlike in previous experiments with this task, all three arms were available during the animals’ second choices. The rats tended to perseverate in their second choices by returning to the arm that they had erroneously visited on their first choice. In Experiment 1, the accuracy of second choices following first-choice errors was below chance during the first block of sessions, when a 90-sec delay intervened between the first choice and the second choice, and at chance during the second block of sessions, when a short (5–6 see) delay intervened between first and second choices. In Experiment 2, long-delay and short-delay sessions were randomly presented to naive subjects. Similar results were obtained. In both experiments, the tendency to repeat the erroneous first choice was greater when long delays separated the two choices than when short delays were used. The results suggest that rats make their first-choice errors because they erroneously encode or remember the location of the sample and that they base their second choices on the same erroneous-memory. The increase in perseveration at long delays implies some kind of rehearsal-like mechanism that slows forgetting of the memory controlling the first choice. 相似文献

ABSTRACT Nursing Assistants (NAs) are the largest workforce in nursing homes, but often lack adequate preparation for their role. The Living Classroom (LC) is an integrated learning approach, whereby a NA program is delivered in a nursing home (NH) in collaboration with a community college. This paper describes the implementation and evaluation of the LC. Mixed methods were used to gather data from 48 NA students, 5 faculty, and 42 NH staff over 30 weeks. Students, faculty, and nursing home staff described the LC as a positive learning experience. Students’ gerontological knowledge increased over time (p = .0012). Students reported very positive relationships with program mentors and NH residents. The LC provides a unique approach to prepare NAs to work in nursing homes. This model could expand to other educational programs with a gerontology focus. 相似文献

Evidence of comparability is generally needed whenever there are variations in the conditions of an assessment administration, including variations introduced by the administration of an assessment on multiple digital devices (e.g., tablet, laptop, desktop). This article is meant to provide a comprehensive examination of issues relevant to the comparability of scores across devices, and as such provide a starting point in designing and implementing a research agenda to support the comparability of any assessment program. This work starts with a conceptual framework rooted in the idea of a comparability claim—a conceptual statement about how each student is expected to perform on each of the devices in question. Then a review of the available literature is provided, focusing on how aspects of the devices (touch screens, keyboards, screen size, and displayed content) and aspects of the assessments (content area and item type) relate to student performance and preference. Building on this literature, recommendations to minimize threats to comparability are then provided. The article concludes with ways to gather evidence to support claims of comparability. 相似文献

Visual cues have an important role in food preference for both rats and humans. Here, we aim to isolate the effects of numerosity, density, and surface area on food preference and running speed in rats, by using a forced-choice maze paradigm. In Experiment 1, rats preferred and ran faster for a group of multiple smaller pellets rather than a single large pellet, corroborating previous research (Capaldi, Miller, & Alptekin Journal of Experimental Psychology: Animal Behavior Processes, 15(1), 75–80, 1989). Further experiments tested the prevailing hypothesis that multiple food pieces are more reinforcing because they occupy a larger surface area. Experiment 2 controlled for numerosity by utilizing a continuous food: mashed potatoes flattened to cover a larger surface area or rounded into a ball. The rats preferred and ran faster for the flattened potatoes, suggesting surface area plays a role in quantity estimations. Finally, in Experiment 3, rats displayed no preference or difference in running speed between a group of scattered and clustered pellets when number of pellets were kept constant. Taken together, these results suggest that density has an important role in food perception—that is, the rewarding effect of higher numerosity or larger surface area is removed when the food does not fill out the entire space. Alternative explanations and implications for human diet are discussed. 相似文献

While a vast literature exists on students and their learning, work on lecturers and their teaching continues to lag some
way behind. This paper explores the notion that the complexity of Higher Education (HE) today significantly impacts upon what
goes on in the classroom through a two-tiered study. Semi-structured interviews were conducted to explore lecturers’ perceptions
and experiences of teaching a specific module. Interviewees raised issues pertaining to the wider departmental, institutional
and socio-political context. Consequently, focus groups were run with key people in the University to explore their perceptions
of teaching and learning within the current HE climate. The findings suggest that lecturers perceive numerous external factors
to impinge upon their teaching and attempt to militate against these in various ways in order to achieve ongoing enhancement
of learning for students.

The emotional and intellectual advantages claimed for teaching by discovery have a long history, but actual designs for instructional environments in which discovery learning is facilitated are still all too rare. Contrary to many people's assumptions, the Socratic dialogues show no evidence of discovery-based learning, nor are they even examples of good questioning technique. Those who work with hypertext need to give deep thought to what it means to discover while being told. 相似文献

This study examined perceptions of college of education students and their experiences with Channel One, a privately-owned
news service used in public education. Given that about one-third of middle and high schoolers in the US view the broadcast
every school day, the authors surveyed 172 freshmen to discern their views and attitudes toward Channel One programming and
commercials and the role colleges and universities might play in relation to this media service. While most studies on Channel
One have been conducted from a K-12 point of view, the goal of this study was to reconsider the topic from the perspective
of prospective teachers and post-secondary education.

The dramatic growth in the number of children learning English as a second language in our country has led to a corresponding
increase in the need to understand how teachers and schools can effectively teach children who are learning English as a second
language. Many teachers report not feeling prepared to meet the needs of these children (National Center for Education Statistics,
Teacher preparation and professional development: 2000. , 2002). The current study used focus group interviews to examine how Head Start teachers in one program addressed the special learning
needs of children learning English in their classrooms. Key challenges involved communicating with children and their families
in their home language. Teachers used other staff, parents, and children in the classroom to interpret. Strategies involved
visual aids, pictures, gestures, and a welcoming classroom environment. Resources used by teachers were professional development
and language skills of other staff. However, available resources were often underutilized and limited for teachers to use
in meeting the challenges the teachers faced in the classroom. Suggestions are presented for overcoming the challenges and
limited resources encountered by teachers, such as changes in preservice and inservice training opportunities, and second
language learning opportunities for teachers. Further implications for training and research are discussed. 相似文献
