为了减小目前常用坐标放样方法中手工输入全站仪数据对作业精度和速度的影响,利用CASS、SV300等数字测图软件相应功能提取各设计点的坐标值,把这些设计数据与控制点数据合并成一个数据文件后,将此数据文件通过数据线传输到全站仪内存文件中,现场利用全站仪自带的坐标放样软件,快速准确地进行放样,从而实现了坐标放样的内外一体化. 相似文献

不少教学第一线的教师和教育研究人员都逐渐认识到：作文批改单一地采用“精批细改”的方式,只能是舍本求末、劳而无功。在新课标背景下,不少语文教师创造了许多作文批改的新形式。如：让学生积极参与,自主自改等,文章着重是从让批改作文的主体由教师变为师生结合乃至学生自己的角度,谈作文批改中取得的教学实效。 相似文献

In higher education (HE), effective feedback on student assessments plays a vital role in retention and in the development of self‐regulating learners, particularly in the first year. In distance learning, where large population modules are common, assignment feedback is generally supported by standard marking guides, issued to the numerous tutors responsible for assessing student work. In this paper, we develop a taxonomy of feedback and report on the results of a survey of tutor attitudes to, and strategies for, providing feedback on a very large Level 1 Open University module. We analyse the extent to which the marking guides afford adequate support for truly effective feedback, and make a number of recommendations for reworking assessment regimes and marking guides. 相似文献

Quality and Qualms in the Marking of University Assignments by Sessional Staff: An Exploratory Study 总被引：3，自引：0，他引：3
The higher education sector is increasingly reliant upon casual (‘sessional’) staff for teaching and marking purposes. While
this practice has been little examined in the past, over the last few years increasing attention has been paid to the quality
of marking, mainly because students and academic staff alike are becoming increasingly likely to question examples of poor
practice. Hence, many universities in Australia are now attempting to introduce stricter procedures relating to marking. Despite
current concerns, there is little published research on marking practices in Australian universities. This paper adds to the
body of knowledge by reporting on two pieces of empirical research into the use of casual markers. A project at Charles Sturt
University comprised focus groups of, respectively, students, lecturers and markers, and a survey of distance education students.
Research at the University of South Australia focused on pedagogical issues relating to marking, comparing the approaches
of permanent lecturing staff with those of sessional markers. The results of these projects provide a useful insight into
areas of current concern to university staff and management. 相似文献

When it comes round to marking assignments: how to impress and how to ‘distress’ lecturers … 总被引：1，自引：1，他引：0
What do lecturers look for when marking essays? What impresses them and what frustrates them? In this paper, we present the results of a survey which asked lecturers to address these questions. Thirty‐two lecturers responded to an email survey in which they listed the problems they found most frustrating when marking essays and the factors which most impressed them. This resulted in 206 comments related to sources of frustration and 139 comments listing factors which impress them. The comments were then coded into themes and ranked in order of importance by 16 lecturers from the original sample. The results highlight a range of issues that may be useful for lecturers when discussing assignments, and instructive for students when writing their assignments. 相似文献

Feedback can have a great impact on student learning. However, in order for it to be effective, feedback needs to be of high quality. Electronic marking has been one of the latest adaptations of technology in teaching and offers a new format of delivering feedback. There is little research investigating the impact the format of feedback has on quality of feedback and subsequently on student learning. This study sets out to investigate the impact paper-based and electronic methods of assignment submission and return have on students’ and markers’ perceived quality of feedback. Students and markers on an undergraduate course were asked to complete an anonymous online survey investigating their perceptions of quality, format and timeliness of feedback delivered electronically and on paper. The results showed that marking and providing feedback electronically was an acceptable method for markers, reporting improved speed and consistency of marking. There was no increase or decrease in satisfaction with the feedback received. Overall, electronic marking was found to be an acceptable method of delivery of feedback on written assignments by both students and markers. The findings of this study suggest that electronic marking can result in more timely feedback for students without impacting on quality. 相似文献

Anonymity in marking is a contentious issue within higher education. Conflicting research findings have identified issues surrounding gender bias, ethnicity bias and fairness in marking. However, the effects of anonymity upon feedback mechanisms have not been systematically explored. This study sought to understand the effects of anonymous marking and feedback upon students’ perceptions of its potential for future learning and relationship building with their lecturers. First year United Kingdom undergraduate business, politics, pharmacy and french students experienced anonymous and non-anonymous marking of coursework across different modules. Student performance data were collected, and a survey was administered following the completion of their modules. Results revealed that anonymous marking did not seem to advantage or disadvantage particular groups of students in terms of grade outcome. There was no significant difference in perceptions of fairness according to whether or not marking was anonymous. Furthermore, the results suggest that anonymous marking might undermine the learning potential of feedback, and minimise the strength of the relationship between lecturers and students, which may minimise the role of dialogue in the feedback process. 相似文献
