How to combine objectives and methods of evaluation in iterative ILE design: lessons learned from designing Ambre-add

This article deals with evaluating an interactive learning environment (ILE) during the iterative-design process. Various aspects of the system must be assessed and a number of evaluation methods are available. In designing the ILE Ambre-add, several techniques were combined to test and refine the system. In particular, we point out the merits of combining measures of the ILE's impact on learning with analyses of the learner's activity. In this article, the approach used to evaluate Ambre-add is described and analyzed, and its advantages and disadvantages are discussed. Then, a general procedure for evaluating ILEs during iterative design is proposed.     

Discourse measures for Basque summary grading

In the context of Learning Technologies, the need to be able to assess the learning and domain comprehension in open-ended learner responses has been present in artificial intelligence and education since its beginnings. The advantage of using summaries is that they allow teachers to diagnose comprehension and the amount of information remembered from text in the learning process. This study addresses the issue of automatically obtaining overall discourse scores from surface discourse measures for Basque language. Global measures have been studied for cohesion, adequacy and use of language. The approach taken was to estimate the presence of the automatically gathered surface discourse measures in expert grading decisions in cohesion, adequacy and use of language. As a consequence, three grading decision-making regression models were obtained to estimate overall grades from text written in Basque. Next, the obtained regression models were tested in corpus-containing summaries written by learners with different degrees of summarisation maturity. The results show that the obtained grading frameworks significantly reflect human decisions and are able to discriminate summarisation maturity differences.     

Stability and Change in Student Teachers’ Beliefs about Teaching

This study examined whether teachers prioritize the use of technology. More specifically, this paper focused on how Turkish teachers think about the importance of technology and technological tools for their daily routines. The research design employed both qualitative and quantitative methods. The data were collected through document analyses, interviews, and a survey. The results showed that the following factors lead teachers to prioritize the use of technology in the classroom: (a) globalization, (b) society’s needs, (c) technological literacy, (d) student learning, and (e) practicability.     

英国圈地运动对我国创新农业经营体制的启示

圈地运动是英国资本原始积累的重要手段,它是英国历史上影响深远的历史事件。圈地运动改变了英国当时的生产关系和产业结构,促进了英国资本主义的产生和发展。它对农民的影响表现为：一方面是一批农民流离失所的祸首,另一方面是一部分农民翻身的机遇。2013年中央一号文件聚焦＂三农＂问题,核心是鼓励土地使用权有序流转,创新农业生产经营体制,实现规模经营。圈地运动时期的英国虽与我国在历史条件、社会形态、社会环境等方面有较大不同,但其土地制度改革的经验教训,对我国实行新型农业生产经营体制、实现规模经营和农业现代化有一定积极意义。
