The effect of expertise-based training on the quality of digital stories created to teach mathematics to young children

This study investigated the effect of expertise-based training (XBT) on the quality of digital stories created by early childhood education (ECE) pre-service teachers. The participants of the study were 69 pre-service teachers from the ECE Department. The study was experimental, utilizing a static-group pre-test/post-test design, supported with qualitative data. Data were collected through analysis and evaluation of digital stories, open-ended questionnaire, and journals. During analysis, an independent t-test was conducted and open coding analysis was applied. The results showed that the XBT group teachers earned significantly higher scores on their digital stories than the traditional group. Moreover, the XBT group focused more on the details of digital story creation, such as emphasizing the purpose of the story during each component; choosing an appropriate tone of voice; using pictures, including characters as Pepe, Kayo, and The Smurfs; and defining key words then applying pictures accordingly.

基于A3000的模糊-PI双模控制实验设计与开发

为改变目前模糊控制大都仍停留在理论分析和系统仿真阶段,缺乏实验验证和工程实际应用的现状,在已有A3000高级过程控制实验装置基础上,利用西门子编程软件STEP7及组态王软件,设计开发了双容液位模糊-PI双模控制系统。介绍了其实现方法及模糊-PI双模控制原理、应用程序开发、系统运行调试等。该实验为模糊控制教学提供了一个模拟工业过程控制的实验平台。     

More about increasing the quality of educational intervention research: A synthesis

A synthesis of the commentaries to our leadoff paper is presented, along with our replies to some of the specific comments offered. When the original analysis and the commentaries are combined, an exceptionally thorough summary of issues that should be considered by intervention researchers emerges. We hope this set of issues will be useful to the educational research community.A draft of this synthesis was circulated among the commentators in this special issue, with a request to determine whether their views were represented fairly. There were few reservations expressed, and in every case when a concern was expressed, we concluded on review that slight adjustment was required to present the commentator's perspective more clearly and/or fairly, and we attempted to do so.
