我国高中阶段教育经费投入分析

1998-2008年间,我国高中阶段的教育经费投入总量不断增加,但是占全部教育经费投入的比例呈逐年减少的趋势;高中阶段财政预算内教育拨款的增长速度快于高中阶段教育总经费投入的增长速度,低于全部财政预算内教育拨款的增长速度;高中阶段的在校生数量特别是普通高中的在校生数较多,随着高校招生人数的增多,高中的升学率也在拔高;我国高中阶段平均预算内经费的增长,要远远落后于我国公共财政能力的发展;高中阶段的中等职业学生平均学费占城市居民人均投入的总比例明显高于普通高中生平均学费占城乡居民收入的比例。     

基于TPACK框架的话语分析:师范生在教学设计过程中关注什么?

教师的信息技术整合能力一直是国内外研究者关注的问题。整合技术的学科教学法(TechnologicalPedagogical Content knowledge,TPACK)概念的提出为这方面的研究提供了理论框架。2010年12月2日至19日,上海市某高校开展了一次职前教师教育微型课程。在之前的一项研究中,研究者使用前后测量表的数据,分析了微型课程前后师范生TPACK水平的变化情况。在随后的研究中,研究者深入到微型课程的实施过程中,对师范生的话语进行记录,并按照TPACK框架进行话语编码和分类。通过统计各类话语的比重,从班级、小组两个层面呈现出师范生在近似真实的教学设计过程中的关注焦点的变化情况,从而为以培养教师的信息技术整合能力为目标的教师教育课程提供建议。

FUNCTIONS OF THE TWO‐YEAR COLLEGE CURRICULUM: FACULTY PERCEPTIONS

There are limited empirical data on curriculum in two‐year colleges; this study is designed to address that lack. A literature review is used to identify the functions served by credit courses: transfer, general education, preparation for work, and remediation. Secondary analysis is made of data gathered on a 1977 survey of science, social science, and science‐related technical courses. Instructor perceptions of course purpose(s) are used to determine if the identified functions are served. The findings indicate these functions are served, but predominately as combined functions rather than the discrete functions identified in the literature. Patterns of multiple course functions are identified by academic area and by course. Further, the methodology used is presented as a useful tool in developing empirical data about college curricula.     

Business problems analysis: An integrated skills development

Abstract

Business Problems Analysis (B.P.A.), a skills based course, is a core component of the B.A. Buslness Studies Degree at Hatfield Polytechnlc. Thls course, which has been running for six years, has very little formal input, rather, students, individually and in groups, experience a range of tasks which are designed to develop their personal competences. These competences are needed throughout working life, and, specifically, in order to cope with the placement period, which occurs during the third year of the course.     

COMMUNITY COLLEGE STUDENTS' OPINIONS REGARDING THE VALUE OF THEIR FRESHMAN SEMINAR EXPERIENCE

Students enrolled in a community college freshman seminar course were interviewed to gather qualitative data on their opinions regarding the value of the course. Existing dissatisfaction among students, faculty, and administrators initiated this study . Data analysis revealed that randomly grouping students with wide - ranging levels of academic abilities and life experiences in a freshman seminar class had a number of drawbacks, as older adult learners differ greatly from younger student learners in aptitude, ability levels, maturity, and academic needs. The findings suggest that older adults need a different kind of freshman seminar course than the traditional first - year student, and that "gifted" older students might be used to provide "on - campus apprenticeships" for other first - year students.     

Application of data envelopment analysis on the indicators contributing to learning and teaching performance

This paper applies data envelopment analysis (DEA) to explore the quantitative relative efficiency of 18 classes of freshmen students studying a course of English conversation in a university of Taiwan from the academic year 2004-2006. A diagram of teaching performance improvement mechanism is designed to identify key performance indicators for evaluation in order to help teachers concentrate their efforts on the formulated teaching suggestions. The sensitivity study highlights the priority of the richness of course contents over the other evaluated indicators. The performance improvement mechanism can help decision-makers to design educational policies.     

Load on Bicycle Frame During Cycling with Different Speeds and Gestures

Experiment and dynamic simulation were combined to obtain the loads on bicycle frame. A dynamic model of body-bicycle system was built in ADAMS. Then the body gestures under different riding conditions were captured by a motion analysis system. Dynamic simulation was carried out after the data of body motions were input into the simulation system in ADAMS and a series of loads that the body applied on head tube, seat pillar and bottom bracket were obtained. The results show that the loads on frame and their distribution are apparently different under various riding conditions. Finally, finite element analysis was done in ANSYS, which showed that the stress and its distribution on frame were apparently different when the frame was loaded according to the bicycle testing standard and simulation respectively. An efficient way to obtain load on bicycle frame accurately was proposed, which is significant for the safety of cycling and will also be the basis for the bicycle design of digitalization, lightening and customization.

SciEthics Interactive: science and ethics learning in a virtual environment

Learning in immersive 3D environments allows students to collaborate, build, and interact with difficult course concepts. This case study examines the design and development of the TransGen Island within the SciEthics Interactive project, a National Science Foundation-funded, 3D virtual world emphasizing learning science content in the context of ethical dilemmas. The 2 year development process is examined through the lens of the rapid prototyping instructional design model, following the project from conceptualization to implementation of a 3D simulation. Through expert interviews, focus groups, and working groups, we were able to determine critical scientific and ethical issues to present to learners in the virtual world. We collected data on 53 students using the simulation at universities in the United States and South Africa and evaluated their experience using qualitative and quantitative methods. Results showed that student participants were engaged and motivated by the simulation. The students reported an increase in science knowledge and ethical understanding, but individual experiences varied.

Self-assessment of self-assessment in a process of co-teaching

The present paper engages in a qualitative research of self-assessment of two lecturers and their students within the framework of a mathematics teaching seminar course (a course during which students submit a research final work) at a teachers’ training college in Israel. Two lecturers co-teach in the course – one of them in the discipline of mathematics and the other in the discipline of academic literacy. The study explores the development process of this experience in the course of one academic year. Data were gathered by means of observations, interviews and reflection records, and the data analysis was done by the ‘grounded theory’ method. The research findings indicate that the self-assessment experience of students is far from being faultless.

Course quality in higher education teacher training: What matters for pre-service physics teachers’ content knowledge development?

This study examines the impact of course quality on pre-service physics teachers’ content knowledge (CK) development. Teachers’ CK is one prerequisite to effective teaching. To support teachers in developing CK, the quality of higher education content courses plays a major role. Yet, models of course quality for higher education vary in their dimensions and it is hence not clear how course quality is best conceptualized. To address this issue, we analyzed data from N = 107 pre-service physics teachers’ CK over one year. We used confirmatory factor analysis to determine the number and nature of dimensions for course quality. Next, we used path models to investigate the impact on CK development. Our results show that a four-dimensional model described CK course quality best and that the cognitive support dimension in particular supports CK development. This highlights the importance of focusing on cognitive support for improving pre-service physics teachers’ CK development.     

Technical research on optimization design of contacts of electrical connector

Pin and socket contacts are the key parts of electrical connector as aerospace electronic components. The contacts are also the direct carriers for signal transmitting of electronic equipments, passing the signal from the input end to the output end of electrical connector. The reliability of pin and socket contacts directly influences signal transmission. The goal of this study is to enhance the contact reliability of aerospace electrical connector. Computer simulation analysis was made on contacts performance data by utilizing the simulation system developed by PCL Language of MSC software. Furthermore, the results were experi- mentally validated so as to realize the objective of optimizing contacts design.
