Professional knowledge or motivation? Investigating the role of teachers’ expertise on the quality of technology-enhanced lesson plans

In an expertise study with 94 mathematics teachers varying in their relative teacher expertise (i.e., student teachers, trainee teachers, in-service teachers), we examined effects of teachers' professional knowledge and motivational beliefs on their ability to integrate technology within a lesson plan scenario. Therefore, we assessed teachers' professional knowledge (i.e., content knowledge, pedagogical content knowledge, technological knowledge), and their motivational beliefs (i.e., self-efficacy, utility-value). Furthermore, teachers were asked to develop a lesson plan for introducing the Pythagorean theorem to secondary students. Lesson plans by advanced teachers (i.e., trainee teachers, in-service teachers) comprised higher levels of instructional quality and technology exploitation than the ones of novice teachers (i.e., pre-service teachers). The effect of expertise was mediated by teachers' perceived utility-value of educational technology, but not by their professional knowledge. These findings suggest that teachers’ motivational beliefs play a crucial role for effectively applying technology in mathematics instruction.     

中国传统文化与学校体育可持续发展

中国传统文化是学校体育可持续发展的外环境因素，它主要由儒家、道家和禅宗文化构成，具有中庸和平、泛道德性、人文精神、非独立性、静止停滞、乡土情结等特质，通过研究它的理性因素对学校体育可持续发展的正面影响和非理性因素带来的负面影响，来探讨在学校体育思想、内容和方法上应采取的发展对策。

异化理论与媒介批判

本文从马克思的“异化理论”与卢卡奇的“物化理论”出发 ,对媒介批判的内容与目的进行了反思 ,提出媒介批判的内容应涉及“媒介产品的异化”、“媒介活动本身的异化”、“媒介组织与媒介从业者的异化”、“媒介组织与其他参照物之间的异化”等诸多层面 ,媒介批判的目的就是从当今社会媒介的异化现象出发 ,找寻媒介“扬弃异化”的方法与途径 ,在批判与超越中使人们逐渐摆脱被自己创造物“奴役”的状况 ,从而实现社会个体与社会整体的自由发展与全面进步。

The impact of digital technology on archival science

Archival science is to be regarded as a system. The properties of that system can be investigated and integrated. The methodology to do so has been tested in two research projects which are presented in this article as examples of the way in which the view of archival science as a system supports the development of new knowledge and as a demonstration of the stability of archival theory. This article presupposes that the archival discipline is also a “science”. Many have argued against the idea on the basis of a common perception that a science is a type of study entirely objective by virtue of the rigorous manner in which it is carried out and the restricted range of topics to which it applies. In fact, the activity of science is based upon a complex framework of assumptions that make it possible for the landscape of the scientific endeavour to be redrawn over time, and, while striving towards objectivity, considers it to be an unattainable ideal.
