Searching for an adequate method to investigate human development (especially the development of theoretical thinking) Vygotsky and his collaborators developed the causal genetic method. The basic idea of this method consists in the investigation of psychic functions and structures by their formation under controlled conditions (for instance via a formation experiment in classroom). But is this method also applicable in instructional settings using modern communications media?This paper is an attempt to find an answer to the question: By what means is the investigation of the formation of theoretical thinking realizable through the application of the causal-genetic method in instructional settings using hypermedia and distance learning? However, a closer examination of the question itself shows that there are three interrelated aspects, namely: the investigation and formation of theoretical thinking; distance learning using modern communications media; the causal-genetic method.It will be shown that in a formation experiment learning with a hyper-media-educational program, which is based on the theory of learning- activity, students reach a new level of cognitive development which is characterized by the growing ability of complex and dialectical thinking.  相似文献

Special services usage and related assessment procedures were investigated for 50 students with epilepsy. Fifty‐six percent of students with epilepsy received special education services, with mental retardation designation and self‐contained placement common, especially among individuals with epilepsy plus a coexisting neurological diagnosis. Sixteen percent of participants had an “other health impairment” designation, and several of these were deemed eligible in at least one other special education category. The majority of students who had been evaluated were administered IQ, adaptive behavior, speech/language, and sensorimotor components, whereas few were assessed for executive or memory functions. Little information about antiepileptic drugs, their effects, or the actual manifestation of students' seizures appeared in special services school documents. Additional empirical information regarding services for children with chronic health conditions, such as epilepsy, is necessary to improve school psychologists' practice. © 2006 Wiley Periodicals, Inc.

The early identification of children with learning disabilities (LD) is difficult but can be accomplished. Observation of key behaviors which are indicators of LD by preschool and kindergarten teachers can assist in this process. This early identification facilitates the use of intervention strategies to provide a positive early experience for children at risk for academic difficulties.  相似文献

The use of the computer and in particular the micro‐computer, by the student provides the opportunity for a significant review of the syllabus and the way in which it is taught. The commercial use of the computer should make us re‐evaluate the content of certain syllabuses, particularly those dominated by mathematical modelling.

Structural Analysis, in the disciplines of Civil and Structural Engineering is a particular case in point since virtually all of the professional numerical analysis of structures is now carried out by a computer. If this is the case, we must seriously ask ourselves why we are teaching the students to carry out lengthy calculations which will never be used in practice.

The computer may be the engine of change for the syllabus content but it offers in return facilities for learning, particularly in formative assessment, unavailable before.

The student may use the computer to test various ideas about the way a structure works under various loading conditions and thereby acquire an understanding of structural behaviour which may not be available in the design office.  相似文献

The impact of mother-child interaction on preschoolers' social-emotional competence was evaluated. Twenty-five girls and 23 boys (mean age = 44 mos) and their mothers were videotaped performing four play/teaching tasks. Preschool teachers completed the Baumrind Preschool Behavior Q-Sort and the Behar Problem Behavior Questionnaire. Mother-child interaction aggregates represented task orientation, positive emotion, and allowance of autonomy/reliance on mother. Results indicated that specific maternal interaction aggregates coherently predicted the children's Positive Social Behavior, Assertiveness, and Sadness in the preschool setting. Child aggregates were less effective predictors of teachers' ratings. Several gender differences in the prediction of social-emotional competence were found (e.g., maternal allowance of autonomy predicted girls' sadness, but boys' sadness was predicted by their own negative emotion). These findings' contributions to the parent-child literature are discussed.  相似文献

Do young boys and girls understand what leads to academic success (e.g., talent, effort, good teaching, luck) in the same way? Do young girls and boys have equivalent perceptions of their academic competence? Are these beliefs engendered in the same way across sociocultural contexts? In a cross-cultural study of over 3,000 children in grades 2 to 6, ages 7.2 to 13.6, we discovered that boys and girls around the world have very similar ideas about what generally leads to academic success. Moreover, in the few contexts where boys' and girls' academic performances were equal, their beliefs were also equal. However, when girls outperformed boys, their beliefs in their own talent were no greater than boys' beliefs, even though they did have stronger beliefs than boys in other facets of their achievement potential (e.g., putting forth effort, being lucky, getting their teacher's help). Our findings support the generally close correspondence between children's achievement and their competence-related beliefs, with the exception that young girls appear to specifically discount their talent. The effects held regardless of the children's achievement, intelligence, or age (approximately 8 to 13 years). Girls were more biased in some contexts than in others, however, suggesting that competence-related biases are rooted in culture-specific aspects of school settings.  相似文献

Children’s obesity rates have increased substantially over the past several decades, due in part to unhealthy eating habits. About 75% of preschool-aged children consume fewer fruits and vegetables than recommended for health. Because children begin developing eating habits during early childhood, obesity prevention programs are increasingly targeting young children in early childhood education (ECE) settings and are involving their families in teaching about healthy eating. The purpose of this pilot study is to assess the effectiveness of a family involvement activity known as the family backpack in increasing fruit and vegetable consumption among 4- and 5-year-old children and their parents through hands-on activities that encourage them to explore and discuss fruits and vegetables at home. Forty-two families (22 experimental, 20 control) participated in the study. Families received a family backpack from their child’s ECE teacher and completed activities with their child at home during a specific week. Experimental-group backpacks contained a children’s book and three activities to encourage parent–child discussion about fruits and vegetables; control-group backpacks contained an unrelated book and activities. Children’s and parents’ fruit and vegetable consumption and frequency of serving fruits and vegetables at home were assessed using parent self-report surveys before and after completing backpack activities. Parents in the experimental group, but not the control group, reported increases in their own and their children’s fruit and vegetable consumption after completing family backpack activities. Family backpacks show promise as a tool for early childhood educators to help families reinforce and expand children’s learning and encourage healthy eating habits at home.  相似文献

Balancing self-care and other-care is often a struggle for career counselors and others in the helping professions. The process of caring is made up of a constant series of empathic attachments, active involvements, and felt separations. The ability to continually engage in the caring cycle is important for success. However, the constant need to re-create the cycle of caring can lead to counselor depletion and burnout. This article provides a developmental framework for assisting career counselors to avoid depleted caring while prolonging their professional longevity. The model of self-care includes recognizing the hazards of high touch work, such as limited resources and constant one-way caring. Also addressed are specific means of professional and personal sustenance, such as maximizing experiences of professional success and balancing personal wellness throughout one's career.  相似文献
