Visualization of the complex courses of the cranial nerves by students in the health‐related professions is challenging through either diagrams in books or plastic models in the gross laboratory. Furthermore, dissection of the cranial nerves in the gross laboratory is an extremely meticulous task. Teaching and learning the cranial nerve pathways is difficult using two‐dimensional (2D) illustrations alone. Three‐dimensional (3D) models aid the teacher in describing intricate and complex anatomical structures and help students visualize them. The study of the cranial nerves can be supplemented with 3D, which permits the students to fully visualize their distribution within the craniofacial complex. This article describes the construction and usage of a virtual anatomy platform in Second Life?, which contains 3D models of the cranial nerves III, V, VII, and IX. The Cranial Nerve Skywalk features select cranial nerves and the associated autonomic pathways in an immersive online environment. This teaching supplement was introduced to groups of pre‐healthcare professional students in gross anatomy courses at both institutions and student feedback is included.

Student Response Technology (SRT) involves the use of hand‐held remotes by students during classroom lectures to electronically respond to questions. This study surveyed 350 students enrolled in one of 13 lower‐division university science classes taught by five different instructors who used SRT. The survey probed students’ perceptions of SRT in terms of enhancing student learning, and investigated which features of SRT students felt had the greatest/least impact on student learning. The majority of students reported that the SRT increased their content understanding, class participation, alertness, and interactions with fellow students, helped with examination preparation, provided important and immediate instructor feedback, and made class more enjoyable. Students in this study scored more positively than peer groups on survey questions related to student engagement in academic and intellectual experiences, suggesting that SRT helps to promote student engagement. Important instructor actions identified during this study that augment the enhancing effects of SRT on student learning, even in large lecture settings, include designing clear, substantive questions, reviewing correct and incorrect answers with students, and making pedagogical adjustments based on class responses. 相似文献

A number of studies have found that teachers are prone to leave schools serving high proportions of low-achieving, low-income, and minority students for more economically and educationally advantaged schools. In schools with very high turnover rates, this can pose a number of challenges, including lack of continuity in instruction, lack of adequate teaching expertise for making curriculum decisions and providing support and mentoring, and lost time and resources for replacement and training. If high rates of turnover are caused largely by student characteristics, then policy strategies to correct the problem are limited. However, due to data constraints, little research has sought to disentangle the effects of student demographic factors from occupational factors such as salaries and working conditions that may also influence turnover and are amenable to policy interventions. Using California teacher survey data linked to district data on salaries and staffing patterns, this study examines a range of school conditions as well as demographic factors and finds that high levels of school turnover are strongly affected by poor working conditions and low salaries, as well as by student characteristics. Although schools' racial compositions and proportions of low-income students predict teacher turnover, salaries and working conditions-including large class sizes, facilities problems, multitrack schools, and lack of textbooks-are strong and significant factors in predicting high rates of turnover. Furthermore, when these conditions are taken into account, the influence of student characteristics on turnover is substantially reduced. 相似文献

Assessment for learning approaches, such as peer review exercises may improve student performance in summative assessments and increase their satisfaction with assessment practices. We conducted a mixed methods study to evaluate the effectiveness of an oral peer review exercise among post-graduate students. We examined: (1) final assessment grades among students who did and did not take part in the peer review exercise; (2) student perceptions of the impact of the peer review exercise; and (3) student understanding of, and satisfaction with, this new assessment practice. We found that students who took part in the exercise had a significantly higher mean grade in a subsequent summative oral presentation assessment than students who did not take part in the exercise. Students gained a better understanding of assessment and marking criteria and expressed increased confidence and decreased anxiety about completing the subsequent summative assessment. Assessment for learning improves academic attainment and the learning experience in postgraduate students. 相似文献

在我国美术院校的艺术教学中,素描教学一直是造型艺术学科的一个重要课题。素描是最直接的造型艺术形式,以培养学生的造型能力为宗旨,学生自觉地、创造性地学习具象绘画的艺术精髓,在艺术实践中不断加深和提高艺术审美能力和艺术表现能力,提升他们的艺术思维能力、想象力、创造力以及敏锐的观察力和准确的判断力。现代抽象素描,它依托于西方现代主义,以形式的创造力、艺术的感知力为表现标准,要求学生以素描的理念为指导,把培养艺术思维观念纳入教学范畴。现代素描丰富了写实性素描的表现理念,有着更广泛的形的美学含义,但其基础还是写实素描,只有在写实素描的基础上,让学生多方位、多角度地去思考造型和表现意识,才能使艺术思维和创造潜能得到充分发挥。 相似文献

The expression “big data” is ubiquitous in the business world today, but few undergraduate business students have the opportunity to gain practical experience with how new business analytics tools can be used in decision making. This article describes a set of hands‐on labs that prepare students to incorporate streaming data analysis into group research projects. Splunk is used to help students analyze and visualize streaming social media data. An evaluation of student projects and student survey results show that this practical approach of training students to manipulate and visualize big data was largely successful in achieving instructional goals. 相似文献

The main purpose of this article is to describe a student exercise about ageing which is part of a university course about the lifespan for social workers. The year‐long course covers development from infancy to old age. In order to describe the context for the ageing exercise, the article also summarises exercises done by students prior to that about ageing. The ageing exercise could be generalised to shorter courses, to ones dealing solely with the elderly, and is suitable for both applied and theory‐based curricula, and to both undergraduate and continuing education. This exercise is compatible with an experiential and reflective approach to learning. Dealing with elderly people is often personally challenging for students as the elderly are at a different part of the life cycle from that of students’ usual friends and acquaintances. The exercise helps students to cope with the unfamiliarity of dealing with individuals unlike themselves, and often proves to be an enriching experience for them. At the same time it enhances their understanding and subsequent ability to relate to the elderly. 相似文献

The research reported here consists of the introduction of an intervention based on a series of laboratory activities combined
with concept mapping. The purpose of this intervention was to enhance student understanding of acid-base chemistry for tenth
grade students’ from two classes in a Turkish high school. An additional aim was to enhance student attitude toward chemistry.
In the research design, two cohorts of students were compared; those from the intervention group (N = 31) and a second group
(N = 28) who were taught in a more traditional manner. Student understanding of acid-base chemistry was evaluated with a pretest/posttest
research design using a purpose-designed instrument, the Concept Achievement Test (CAT) consisting of 25 items, 15 multiple choice and ten multiple choice with explanation. Alternative conceptions identified
in the pretest were incorporated into the intervention, which thereby sought to move students toward views more in accord
with scientific views for the concepts. Statistical tests indicate the instrument is reliable (with an alpha reliability of
0.81) and the analysis of the findings revealed statistically significant differences between the intervention and traditional
groups with respect to conceptual understanding. Examination of student explanations and analyses of semi-structured interviews
conducted with selected students suggest that the main influence was the laboratory activities. Analysis of the findings in
the context of relevant literature that concept mapping in conjunction with laboratory activities is more enjoyable, helps
student link concepts, and reduces their alternative conceptions. 相似文献

This article describes a method used to provide mathematics students in colleges of engineering in Japan with supplementary exercises to aid in their learning. The impact of this effort is also described. An online support function enables instructional personnel to individualize the exercise for students whose abilities vary widely. Individualizing exercises helps students to understand a mathematical method used to solve a problem and also the mathematical idea or concept upon which the method is based. The program described here consists of activities that supplement those in the regular lesson. They are designed to help those students who failed to meet certain course objectives or to solve the problems given in the lesson. Students using the individualized program are allowed to select the problems from among the problem exercises available based on the course objectives that they have not yet satisfied. The online support function of the learning environment that the authors developed assists teaching personnel in the otherwise time-consuming preparation of individualizing these activities. Students determine how well they did on the objectives in the regular lesson by visting the Web page for the course. Information is provided on the impact of the activities on student performance in a fundamental mathematics course in the authors college. 相似文献

Teaching quantitative subjects such as operations management (OM) can be quite challenging. In this article, we present a novel approach that uses simplified concept maps for teaching OM. This application of concept maps was investigated to determine if it helps students to answer questions and to solve OM problems more effectively. Our study used a controlled experimental design with students divided into two groups, one taught using concept maps and another group taught using traditional techniques. Student learning was measured with pre‐ and posttests consisting of both multiple‐choice and constructed‐response items. The performance of the two groups was compared using an independent samples t‐test and analysis of covariance to control for the covariate “pretest.” The results indicate that use of simplified concept mapping significantly improved student learning of OM course material. We therefore recommend its adoption as an active‐learning pedagogical technique that can lead to positive change in the OM classroom. 相似文献

We have analysed the processes of argumentation of three university student groups (A: six students, C: five students, and J: seven students) while making a decision about an environmental problem (selection of a heating system). The discussions took place in three 1½‐hour sessions that were audio‐taped and transcribed. For the analysis of the oral discussions, on the one hand, we have taken into account some of the dimensions characterising the quality of this decision‐making process, including the number and variety of criteria utilised, whether criteria, which did not favour the selected option, were considered and whether priorities were established among criteria, and, on the other hand, the use of environmental concepts such as renewable and sustainability as well as the meanings that were constructed for both concepts. We have determined that the students in this study proposed and utilised, both explicitly and implicitly, a high number and great variety of criteria to support their choices, although they were rarely able to consider contradictory evidence; that is, those that demonstrated disadvantages of the option selected. In terms of the construction of knowledge, we observed that in some groups the proposed task favoured the construction of a concept of sustainability that took the future into consideration and which was utilised as the most important justification in their selection. In terms of the concept of renewable, we found that they did not relate depletion of resources to economic consequences. We discuss the implications for the educational competence development. 相似文献

Planning and self-control were examined in relation to preschoolers' (41- to 74-months) saving behavior. Employing a marble run paradigm, 54 children participated in two trials in which they could use their marbles immediately on a less desirable run, or save for a more desirable run. Twenty-nine children received the opportunity to create a budget. On Trial 1, children in the budgeting condition saved significantly more than did children in the control condition, and their planning ability related to saving (after controlling for age and language). Those who consistently budgeted at least one marble for the more desirable run were more likely to save. Control children's performance improved across trials, with no between-condition differences on Trial 2. Self-control was not related to saving. 相似文献
