“网络信息安全”教学平台中教学评价系统的研究与设计

随着网络在生活学习工作等各个方面的普及与应用,特别是无线网络与移动通信网络的发展,教育的网络化趋势日益明显。网络教学平台作为网络教育的载体,是体现教育网络化优势的关键所在。但是目前的网络教学平台主要侧重于教学资源的组织与交流功能的实现,对学生在学习过程中的管理、反馈与评价还是一个空缺,如何有效地对网络教学进行评价是摆在我们面前亟待研究和解决的一个现实问题。本文在网络教学平台基础上分析了教学系统所要达到的总体目标．阐明了其体系结构。并重点探讨了教学评价系统的设计与实现。     

Testing method for objective evaluation of cross-country ski poles

The aim of the study was to develop an objective classification method for cross-country ski poles. A test device was designed to expose different pole models to maximal loading and impact tests. A load cell measured the axial forces in the pole shafts, and a laser distance meter measured shaft deflection when a load was applied via the wrist strap. In the loading tests, each shaft reached a plateau where no more force could be transferred. This maximal force transfer (MFT) value was a characteristic measure for flexural rigidity and thereby also strength. The developed test method enables a loading that is more similar to real-life skiing than a standard three-point bending test. Results show that the introduction of shaft indices for buckling strength is beneficial for comparison purposes. The MFT is a relevant parameter used in the characterization of poles.     

Facebook and sport education: mirroring the model at home to promote parental involvement

ABSTRACT

Social networks had become so important that they constitute a way of life for many individuals, and Facebook is probably the most popular one. Society has become totally connected, but classrooms still remain rather isolated. The goal of the study was to extend the Sport Education Model (SEM) through a social network, Facebook, to promote parental involvement, assessing its impact at home. 41 parents of 49 grade 12th secondary education students agreed to participate (39?57 years): 14 fathers and 27 mothers. The vast majority of participating parents that included information about their socio-economic and educational background considered themselves medium level (11 out of 13). Unfortunately, most parents did not provide this type of information (69.30%). An AcroGymnastics learning unit was implemented using the SEM during 16 sessions. All Facebook activity was recorded by the site, and semi-structured interviews were used to obtain data directly from the parents. Quantitative data was analysed using Gytrics, while MAXQDA 11 helped with qualitative data management. Quantitative results showed that the Facebook group had a notable effect in parents’ involvement: 42.26% joined (67% mothers), 100% reacted, 70.47% published content, 48.69% uploaded a picture/video, 503 posts, 14,528 hits, and 2025 reactions: 1912 likes and 113 comments. Themes derived from the analysis of the qualitative data reinforced the idea that Facebook helped promote parental participation: involvement, affiliation and learning, and some SEM features at home: affiliation, festive atmosphere and participation. Finally, a change in the PE status was also observed among parents. In conclusion, the combination Facebook-SEM had a notable positive effect on parental involvement, especially among mothers of medium socio-economic background. The number and type of activities posted by the administrator seemed to be a key element to positively integrate Facebook in education.     

Assessing the unidimensionality of the School and College Ability Test (SCAT,Spanish version) using non-parametric methods based on item response theory

The aim of this work is to analyze the dimensional structure of the Spanish version of the School and College Ability Test, employed in the process for the identification of students with high intellectual abilities. This test measures verbal and mathematical (or quantitative) abilities at three levels of difficulty: elementary (3rd, 4th, and 5th years in Primary school), intermediate (6th year in Primary school plus the 1st and 2nd years of Compulsory Secondary School or ESO), and advanced (3rd and 4th years of ESO plus the 1st and 2nd years of bachillerato – equivalent to High school). For each level there are two forms, X and Y. The research was undertaken with the results obtained from the application carried out for the validation and norming of the Spanish version of the test, and for which a representative sample of students from Navarre at these mentioned levels was taken. This study assessed the possible unidimensionality of the simplicity or the complexity of the structure of this test as an essential aspect of construct validity. To this end, the results were triangulated for the classic factorial techniques and non-parametric methods based on the item response theory.     

Feedback in educational communication in Czech secondary schools

This paper introduces an empirical study that examines how teachers evaluate pupils?? responses. The study draws on research undertaken at four secondary schools in the Czech Republic. It transpires that feedback has a stable position in the structure of communication; however, it is used only to verify pupils?? responses and not to elaborate them. An important feature of feedback is its implicitness and near-zero content value resulting from the teachers?? preferences to avoid explicit evaluative comments. This type of feedback is not in accordance with the concepts of dialogical education that currently dominate the field of the theory of educational communication.
