Attention-deficit/hyperactivity disorder (AD/HD) negativelly affects the cognitive and psychomotoric spheres of the pupil's social behavior and social adaptation. The review of many studies states that pupils with AD/HD achieve worse learning results because of insufficiently functioning cognitive processess, such as attention, (work) memory, thinking, problem solving, language, small- and large- scale motorics. Behavioral features, exhibited with AD/HD, include low-frustration tolerance, temper problems, persistence, emotional liability, depression, peer rejection, poor self-concept and poor self-esteem. Because of insufficiency of the cognitive processes, the difficulties of social behavior and social adaptation, pupils with AD/HD more often have a dysfunction of pupils' role that manifests by learning difficulties and behavior problems. The manifestation of the disorder in the younger school age in the context of children's school activities and roles actualizes the exceptional interest of the educational science in the analyzed phenomenon. The search and construction of effective means of socio-educational help for AD/HD primary class pupils should be associated with coordination and adaptation of different effective educational methodologies of different conceptual origin. In order to develop cognitive, psycho-motoric abilities and social behavior of the group of primary class pupils with AD/HD (N=22), activities of supplementary education were organized after classes (their duration was 6 months). During the forming experiment, original methodologies were constructed and national and foreign researchers' educational methodologies were adapted and tested in new, specific conditions (methods of fairy-tales, correction of cognitive behavior, graphical-logical tasks, games in the sport hall). Even by relatively rare activities of supplementary education in a homogeneous group of children suffering from AD/HD positive changes of cognitive, psychomotoric sphere, social behavior and social adaptation were achieved. 相似文献

The main objective of this study is (a) to explore the relationship among cognitive style (field dependence/independence),
working memory, and mathematics anxiety and (b) to examine their effects on students’ mathematics problem solving. A sample
of 161 school girls (13–14 years old) were tested on (1) the Witkin’s cognitive style (Group Embedded Figure Test) and (2)
Digit Span Backwards Test, with two mathematics exams. Results obtained indicate that the effect of field dependency, working
memory, and mathematics anxiety on students' mathematical word problem solving was significant. Moreover, the correlation
among working memory capacity, cognitive style, and students’ mathematics anxiety was significant. Overall, these findings
could help to provide some practical implications for adapting problem solving skills and effective teaching/learning. 相似文献

Internet evolution has affected all industrial, commercial, and especially learning activities in the new context of e-learning. Due to cost, time, or flexibility e-learning has been adopted by participators as an alternative training method. By development of computer-based devices and new methods of teaching, e-learning has emerged. The effectiveness of such programs is dependent on powerful learning management systems. In this paper, a neuro-fuzzy approach is proposed based on an evolutionary technique to obtain an optimal learning path for both instructor and learner. The neuro-fuzzy synergy allows the diagnostic model to imitate instructor in diagnosing learners’ characteristics, and equips the intelligent learning environment with reasoning capabilities. These reasoning capabilities can be used to drive pedagogical decisions based on the learning style of the learner. The neuro-fuzzy implementation helps to encode both structured and non-structured knowledge for the instructor. On the other hand, for learners, the neural network approach has been applied to make personalized curriculum profile based on individual learner requirements in a fuzzy environment. 相似文献
