Math anxiety impedes performance in simple arithmetic tasks. Anxiety constrains working memory capacity and particularly the attentional functions of the central executive. The experiment reported here explored how interactivity mitigated the impact of math anxiety on the performance of elementary school students with simple additions. It manipulated two independent variables. The first was the length of the additions—involving either 7 or 11 number tokens (the value of the tokens ranged from 1 to 20). The other was the level of interactivity: in the low interactivity condition participants could not touch or point to the number tokens that configured the sums, and in a high interactivity condition participants could manipulate the tokens as they saw fit in deriving their answer. The length of the addition had an impact on accuracy, with longer sums leading to poorer performance. However, overall, performance in the high interactivity condition was superior, in terms of accuracy, absolute calculation error and efficiency, than performance in the low interactivity condition. Mathematics anxiety significantly predicted performance in the low interactivity condition, but not in the high interactivity condition. These results suggest that working memory resources are augmented through interactivity with the physical problem presentation, defusing the impact of anxiety on performance. 相似文献

This paper examines some of the models used for conceptualizing the possible developmental implications of blindness and severe visual impairment. It takes up the question of the significance in infancy of certain skills and proficiencies, especially motor, that may be impeded by the lack of vision. The paper then addresses such issues for the school age child as access to literacy, with the emphasis being on ways of mitigating the potentially educationally handicapping consequences of visual disability. Educational technology is cited as one of the principal means available to teachers for meeting these challenges, and examples are given of procedures and devices that are being explored. A central argument is that for psychologists, teachers, and educational technologists the search must be to pinpoint the specific and changing needs of the individual learner. 相似文献

The study of pseudoscience and the paranormal is an important but neglected aspect of science education. Given the widespread acceptance of pseudoscientific and paranormal beliefs, science educators need to take seriously the problem of how these can be combated. I propose teaching science students to critically evaluate the claims of pseudoscience and the paranormal, something that can be accomplished in a variety of ways. 相似文献

The signaling function of the second-order CS (S2) was manipulated in second-order autoshaping by arranging a partial reinforcement schedule. S2 was paired with a well-conditioned first-order CS (SI) on a continuous reinforcement or a 25% reinforcement schedule in different groups. Schedule of reinforcement did not influence the number of S2-S1 pairings required to establish keypecking to S2. However, in the postacquisition sessions, responding to S2 was initially weaker but persisted for many more sessions on the 25% schedule than on the 100% schedule. The data indicate that S2-S1 pairings are responsible both for the acquisition of second-order keypecking to S2 and for the subsequent conversion of S2 into an inhibitory stimulus. 相似文献

The research described in this article is a case study of a fifth grade teacher's (Melissa) efforts to construct a teaching
and learning environment within her science teaching. Qualitative research methods were used to examine and analyze Melissa's
science teaching practice. Drawing from socio-cultural theories, I argue that her teaching and learning environment was constructed
as a form of mediated action through which she articulated and transformed the context, meaning, and action of her science
teaching. In particular, she forged links between a number of factors, such as historically recognizable forms of pedagogy,
perceptions of her students' socio-economic positions, knowledge of appropriate science teaching, and her experiences in a
preservice teacher education program. Through her pedagogical work, the teaching and learning environment was articulated
into a complex network of meanings, physical spaces, and concrete actions in which each element transformed the other. I suggest
that mediated action is a form of transformation that constitutes context, meaning, and action into a dynamic and constantly-shifting
teaching and learning environment.

The article examines the construct of happiness within the context of counseling and holistic health (body, mind and spirit).
It discusses happiness as a goal of counseling as reflected in selected counseling theories that focus on humanistic principles,
holistic health, positive psychology, personal growth and the client’s intentional choice-making in life. Moreover, the article
considers within-cultural and cross-cultural implications of happiness, and presents recommendations for counseling professionals
who counsel clients or train future counselors. 相似文献

A continuation of the bibliography published in the Fall 1979 issue of ECU, this article presents an annotated bibliography
of 73 reports of research on the impact of instructional media on attitude formation and change. The author also shares some
general observations about the findings, including procedures most likely and least likely to produce the desired attitudinal
outcomes.
Research for this study was supported by a grant from the Research Institute for Studies in Education, College of Education,
