Promoting technology integration through collaborative apprenticeship

Teachers often learn technology skills and integration strategies in intensive seminars, ineffective means for professional learning because experiences are seldom transferred to instructional practices. Thus, effective technology integration requires teachers to obtain learning experiences within the context of their teaching so they can practice, reflect, and modify their practices. Learning in a teaching community is a social process that involves ongoing, on-site, and just-in-time support. Teachers need avenues to continually interact to provide such support across all members of the community. Collaborative Apprenticeship, a professional development model featuring reciprocal interactions, is one such approach to promoting technology integration. Teachers experienced in technology use serve as mentors of peer-teachers' technology applications aimed at improving instruction. Technology is progressively infused as peer-teachers learn to design technology-rich lessons from their technology-savvy peers through modeling, collaboration, and coaching.

Rehabilitation of socially withdrawn preschool children through mixed-age and same-age socialization

24 socially withdrawn preschool children were located through classroom observations and assigned to 3 conditions: (a) socialization with a younger child during 10 play sessions, (b) socialization with an age mate during a similar series of sessions, and (c) no treatment. The socialization sessions, particularly those with a younger partner, were found to increase the sociability of the withdrawn children in their classrooms. Significant increases occurred mainly in the rate with which positive social reinforcement was emitted. Generally, the results support a leadership deficit theory of social isolation. Possible mechanisms responsible for the observed changes are discussed.     

Supporting learning with interactive multimedia through active integration of representations

When learners explore dynamic and interactive visualisations they are often not able to interact with them in a systematic and goal-oriented way. Frequently, even supporting learners in processes of discovery learning does not lead to better learning outcomes. This can be due to missing pre-requisite knowledge such as the coherent mental integration of the pictorial and symbolic sources of information. In order to support learners in this process, we encouraged them to interactively and externally relate different static sources of information to each other before exploring dynamic and interactive visualisations. We evaluated the benefit of this instructional support in two experimental studies concerning the domains of statistics and mechanics. It revealed that the active integration of static representations before processing dynamic visualisations resulted in better performance and can provide a basis for a more systematic and goal-oriented experimentation behaviour during simulation-based discovery learning.in final form: 16 November 2004     

Toward integration of reading and service learning through an interdisciplinary program

This study examined the effect of an interdisciplinary program of reading and service learning on the cognitive and affective development of university students in Hong Kong. As Nussbaum (1997) stated, literature plays a vital role in educating citizens of the world through its narrative imagination and its power of promoting understanding and empathy toward the life of others. Halstead and Pike (2006) also emphasized that art can foster reflection upon action and bring about change in behavior as a result of perspective change. In this study, 24 freshmen read literary works under the theme of children??s welfare and explored issues related to the welfare of children worldwide. Their reflections on these materials were expressed in writing and in a presentation. In the following semester, the students participated in voluntary services within and outside Hong Kong. All students completed a questionnaire on their humanistic concerns and sense of global citizenship at the beginning and the end of the project. Results showed that students were conscious of their changes after joining the program and stated their growth in values and knowledge. The pre?Cpost-t-test analysis suggested that students had made significant improvement in the following areas: (1) their attitude toward serving others, especially in their personal and social values; (2) their engagement in reading literary and nonfiction works which reflect social and moral issues of the world; (3) their attention to world affairs; (4) their concern for the underprivileged; and (5) awareness of their potential in helping the poor.     

Self-derivation through memory integration: A model for accumulation of semantic knowledge

Semantic knowledge accumulates through explicit means and productive processes (e.g., analogy). These means work in concert when information explicitly acquired in separate episodes is integrated, and the integrated representation is used to self-derive new knowledge. We tested whether (a) self-derivation through memory integration extends beyond general information to science content, (b) self-derived information is retained, and (c) details of explicit learning episodes are retained. Testing was in second-grade classrooms (children 7–9 years). Children self-derived new knowledge; performance did not differ for general knowledge (Experiment 1) and science curriculum facts (Experiment 2). In Experiment 1, children retained self-derived knowledge over one week. In Experiment 2, children remembered details of the learning episodes that gave rise to self-derived knowledge; performance suggests that memory integration is dependent on explicit prompts. The findings support nomination of self-derivation through memory integration as a model for accumulation of semantic knowledge and inform the processes involved.     

Promoting understanding of chemical bonding and spontaneity through student explanation and integration of ideas

This article explores the effectiveness of intervention discussion sections for a college general chemistry course designed to apply research on student preconceptions, knowledge integration, and student explanation. Two interventions, on bond energy and spontaneity, were tested and intervention student performance was compared with that of a control group that did not use the experimental pedagogy. Results indicate that this instruction, which identifies students' initial conceptions and integrates those ideas into class discussion, leads to enhanced conceptual understanding. The intervention group outperformed the control group on a written course midterm, the thermodynamics portion of a standardized American Chemical Society examination, and an in‐depth interview. In interviews, the intervention group students explained the energetics of bond breaking and formation at a more sophisticated level than did the control students. In contrast, control students were more tenuous in their thinking, tended to contradict themselves more when discussing bond energy, and harbored more misconceptions about spontaneity. © 2002 Wiley Periodicals, Inc.

A framework for Information and Communication Technology integration in schools through teacher professional development

Abstract

The demands of the twenty-first century require effective and sustainable use of Information and Communication Technologies (ICTs) in education. Various ICT strategies and initiatives across South Africa have not resulted in system-wide, sustainable ICT integration in schools. Although the roles of principals are acknowledged in educational management, the question remains how principals influence teachers' effective and sustainable integration of ICT through teacher professional development (TPD). A matrix of theoretical criteria selected seven participants across diverse contexts. In-depth interviews produced an integrated dataset that revealed principals' patterns of influence, their perceptions and experiences, their leadership and management styles, their attitudes towards ICT integration, their knowledge on related ICT and related TPD issues, as well as their strategic thinking on ICT integration. The proposed theoretical framework illustrates the interrelatedness of aspects that influence principals' leadership through open distance learning.     

Teacher preparation for equitable access through the integration of TESOL standards,multiple intelligences and technology

Abstract

Schools need teachers who can provide English language learners with equal access to academic content and to information technologies. The authors propose that the integration of standards in TESOL (teaching English to speakers of other languages), the theory of multiple intelligences (MI) and technology can provide an equitable education, support learning differences and develop English language skills across the curriculum. The authors suggest how the integration of TESOL standards, MI theory and technology can become a part of pre-service teacher education and discuss some of the challenges to transferring this integration into the classroom

Riemann integration

Riemann had revolutionized the fields of analysis, geometry and mathematical physics. His ideas concerning geometry of space had a profound effect on the development of modern theoretical physics. Riemannian manifolds, Riemann surfaces, the Cauchy—Riemann equations, the Riemann hypothesis-all these and more are packed into his one-volume collected works. Riemann clarified the notion of integration by defining, a little over 135 years ago, what we now call theRiemann integral. This article is devoted to a study of the Riemann integral.
