Mental health problems of deaf Dutch children as indicated by parents' responses to the child behavior checklist 总被引:2,自引:0,他引:2
Emotional/behavioral problems of 238 deaf Dutch children ages 4-18 years were studied. Parental reports indicated that 41% had emotional/behavioral problems, a rate nearly 2.6 times higher than the 16% reported by parents of a Dutch normative sample. Mental health problems seemed most prevalent in families with poor parent-child communication. Deaf children ages 12-18 showed more problems with anxiety and depression and more social problems than those ages 4-11. Deaf children with relatively low intelligence showed more social problems, thought problems, and attention problems than those with relatively high intelligence. The authors stress the need to get information on deaf children's mental health functioning not just from parents but from other informants such as teachers and the children themselves. An expansion assessment of deaf children, and of special services and treatments for deaf children and adolescents with emotional/behavioral problems, is recommended. 相似文献

Finland and Shanghai are strong performers in the Program for International Student Assessment (PISA). The current study explored the similarities and differences in educational effectiveness between these 2 strong performers. To this end, 14 predictors representing student background and school process characteristics were selected from the PISA 2009 database. The results show that the Finnish educational system is more efficient in transforming given inputs, specially student background characteristics, into reading achievement, while the general condition of the school climate in Shanghai, in terms of value and effect size of the predictors, contributes a large part to its comparative strength in reading achievement. Suggestions for improvement at school and system level are given. 相似文献

This study examined salivary cortisol, a stress-sensitive hypothalamic-pituitary-adrenocortical (HPA) axis hormone in 20 infants (12 females; M age = 10.8 months) and 35 toddlers (20 females; M age = 29.7 months) in full-day, center-based child care. Samples were taken at approximately 10:00 a.m. and 4:00 p.m. at child care and at home. At child care, 35% of infants and 71% of toddlers showed a rise in cortisol across the day; at home, 71% of infants and 64% of toddlers showed decreases. Toddlers who played more with peers exhibited lower cortisol. Controlling age, teacher-reported social fearfulness predicted higher afternoon cortisol and larger cortisol increases across the day at child care. This phenomenon may indicate context-specific activation of the HPA axis early in life. 相似文献

In this paper, we present a case study of a beginning chemistry teacher who enrolled in a project aimed to contribute to the
development of teachers' knowledge of models and modelling in science. The project consisted of a series of institutional
meetings in combination with an action research project the teacher conducted in her own classes. By explaining how the project
was conducted and mainly by focusing on the teacher's voice, her dynamic, continuous, and non-linear process of knowledge
development is discussed in detail. We were able to investigate and describe this development in terms of various types of
knowledge – content knowledge, curricular knowledge and pedagogical content knowledge – which were developed simultaneously.
Among other results, it became clear how certain institutional activities led to specific choices in the teacher's action
research project. For instance, although initially she was reluctant to conduct a modelling activity in her class, she decided
to experiment with such an activity in her action research project. Subsequently, the responses of her students during the
project convinced her of the value of this modelling activity and helped her to become aware of specific views of her students.
Finally, it became evident that the whole experience made her very enthusiastic and stimulated her to formulate specific intentions
with respect to the future, both in terms of applying certain teaching activities and in terms of collaborating with colleagues. 相似文献

Developing technical expertise in secondary technical schools: The effect of 4C/ID learning environments 总被引:1,自引:0,他引:1
In this study, the effectiveness of learning environments, developed in line with the specifications of the four components
instructional design model (4C/ID model) and the additional effect of ICT for fostering the development of technical expertise
in traditional Ghanaian classrooms, was assessed. The study had a one-by-one-by-two pretest–posttest quasi-experimental design.
Three functionally equivalent classes of students from three similar (secondary technical) schools were randomly exposed to
three different treatments. The sample consisted of 129 students. The treatment groups consisted of one control group with
a regular method of teaching and two experimental groups: a 4C/ID learning environment with ICT; and a 4C/ID learning environment
without ICT. The content for the treatments was selected from the secondary technical education syllabus. Technical teachers
were trained to implement the interventions. After the pilot study, the materials were validated by experts and revised. Teachers
were retrained. The main study, consisting of six sessions, was conducted in regular classrooms in three schools. Results
indicated that a 4C/ID learning environment promotes the development of technical expertise in secondary technical education
better than teaching designed in line with a regular method of teaching. Moreover, results reveal no significant difference
in learning gains for the 4C/ID learning environment between the group with ICT and the group without ICT. In the final section,
the theoretical, research and practical implications of the results for the instructional design and technology community
as well as for educational practice, are discussed. 相似文献

Although there is a common understanding of instructional sensitivity, it lacks a common operationalization. Various approaches have been proposed, some focusing on item responses, others on test scores. As approaches often do not produce consistent results, previous research has created the impression that approaches to instructional sensitivity are noticeably fragmented. To counter this impression, we present an item response theory–based framework that can help us to understand similarities and differences between existing approaches. Using empirical data for illustration, this article identifies three perspectives on instructional sensitivity: One perspective views instructional sensitivity as the capacity to detect differences in students' stages of learning across points of time. A second perspective treats instructional sensitivity as the capacity to detect differences between groups that have received different instruction. For a third perspective, the previous two are combined to consider differences between both time points and groups. We discuss linking sensitivity indices to measures of instruction. 相似文献

As teachers' knowledge determines to a large extent how they respond to educational innovation, it is necessary for innovators
to take this knowledge into account when implementing educational changes. This study aimed at identifying patterns in the
content and the structure of science teachers' knowledge, at a point in time when they still had little experience in teaching
a new subject, that is, Public Understanding of Science. We investigated three domains of teacher knowledge: Teachers' pedagogical
content knowledge (PCK), subject-matter knowledge, and general pedagogical knowledge. A semi-structured interview and a questionnaire
were used. From the analysis of the data, two types of teacher knowledge emerged. One of the types was more integrated and
more extended in terms of PCK. Teachers who represented this type of knowledge had developed PCK that connected the various
programme domains of the new science subject. In both types, PCK was found to be consistent with general pedagogical knowledge.
In both types, however, subject-matter knowledge was similar, and not directly related to the other knowledge domains. Implications
for the implementation of the new subject are discussed. 相似文献

In the day-to-day workplace teachers direct their own learning, but little is known about what drives their decisions about what they would like to learn. These decisions are assumed to be influenced by teachers’ current professional concerns. Also, teachers in different professional life phases have different reasons for engaging in professional learning. In this study, we explored the professional concerns underlying teachers’ learning goals in order to understand variation in professional learning over a teacher’s career. In this qualitative study, we administered a semi-structured interview and a card sorting task to 15 secondary school teachers to elicit teachers’ learning goals and current professional concerns. By conceptually combining teachers’ learning goals with professional concerns in concern-goal pairs, we sought to understand the different reasons for teachers’ learning. These concern-goal pairs were characterized in three different types of reasons: continuous, growth and improvement, and work-management. The results showed that early career teachers have mainly growth and improvement concerns, whereas mid- and late-career teachers have both continuous and growth and improvement concerns. Work-management concerns differ for early- and late-career teachers. Results are further discussed in terms of professional life phase models and teachers’ developmental tasks throughout their career. 相似文献

Assessment of Cognitive Load in Multimedia Learning with Dual-Task Methodology: Auditory Load and Modality Effects 总被引:2,自引:2,他引:2
Using cognitive load theory and cognitivetheory of multimedia learning as a framework,we conducted two within-subject experimentswith 10 participants each in order toinvestigate (1) if the audiovisual presentationof verbal and pictorial learning materialswould lead to a higher demand on phonologicalcognitive capacities than the visual-onlypresentation of the same material, and (2) ifadding seductive background music to anaudiovisual information presentation wouldincrease the phonological cognitive load. Weemployed the dual-task methodology in order toachieve a direct measurement of cognitive loadin the phonological system. In bothexperiments, the modality effect could beconfirmed in the patterns of secondary taskperformance and in the primary learning task. 相似文献
