Concept learning by pigeons: Matching-to-sample with trial-unique video picture stimuli

Pigeons were trained to match-to-sample with several new methodologies: a large number of stimuli, computer-drawn color picture stimuli, responses monitored by a computer touch screen, stimuli presented horizontally from the floor, and grain reinforcement delivered onto the picture stimuli. Following acquisition, matching-to-sample concept learning was assessed by transfer to novel stimuli on the first exposure to pairs of novel stimuli. One group (trial-unique), trained with 152 different pictures presented once daily, showed excellent transfer (80% correct). Transfer and baseline performances were equivalent, indicating that the matching-to-sample concept had been learned. A second group (2-stimulus), trained with only two different pictures, showed no evidence of transfer. These results are discussed in terms of the effect of numbers of exemplars on previous failures to find concept learning in pigeons, and the implications of the positive finding from this experiment on abstract concept learning and evolutionary cognitive development.

Comprehension evaluation and regulation in learning from science texts

Metacognitive variables influence students' learning from science texts. This article deals with the comprehension monitoring abilities of secondary school science students, one of the areas of metacognition which has drawn considerable attention from researchers. The aims of the study are, in particular: (a) to know the extent to which comprehension is monitored by secondary science students as revealed by inconsistency detection in manipulated science texts, and (b) to identify the strategies used to regulate comprehension by the students who detect the inconsistencies. The results indicate that knowing that one understands or fails to understand science texts could be as important a problem as understanding proper. Besides, some incorrect regulatory strategies used by students who notice the inconsistencies in the texts are identified. These could also have an annoying influence in the regulatory behavior of students when studying regular science texts.     

VB.NET下多线程技术的实现

线程应用分成多个单元执行,在分布式中,实际上使用一个多线程的体系.本文讨论了VisualBasic.NET对多线程的支持,并从线程的创建与维护,线程的优先级,线程的状态,线程池和线程的同步等方面展示了如何使用多线程技术来创建多线程应用程序.由于操作系统要跟踪和确定线程的进度,线程的系统开销会比较大,因此创建新线程必须谨慎.     

从普通高校学生管理规定谈大学体育课成绩与健康标准的融合

依据教育部三个文件,针对目前我国许多高校争论的热点问题:由体育课成绩还是由体质健康标准作为学生能否顺利毕业的依据而进行调查研究.结果表明:学生体育成绩应该是最终决定学生能否毕业的重要条件.体育成绩应该是体育课成绩、体质健康标准和课外体育锻炼的融合.
