Conclusion Garrison’s (2000) review of distance education theories describes the current need for ”sustained real two-way communication
... that refiect(s) a collaborative approach to distance education” (p. 13). One way to apply such theories to research and
coursework is to use collaborative documents to promote transactions culminating in deliberation among the key players. Such
deliberation can create ”a particular kind of democratic public culture among the deliberators: listening as well as talking,
sharing resources, forging decisions together rather than only advocating positions taken earlier, and coming to disagreement”
(Parker, Ninomiya, & Cogan, 1999, p. 129).
Her research interests are collaborative learning in distance education, impact of culture on online learners, and design
of online instruction for constructivist learning environments.
Her primary research interests are in design considerations for collaborative online environments and in the powers of shared
multimedia for enhancing personal growth, multicultural understanding, and global awareness. She investigates visual messages:
how they can be shared and interpreted by learners, their impact, and how their impact can be researched.
Her research interests are in computer and network-based foreign language and cultural learning. 相似文献

Three approaches to molecular phylogenetics are demonstrated to biology students as they explore molecular data from Homo sapiens and four related primates. By analyzing DNA sequences, protein sequences, and chromosomal maps, students are repeatedly challenged to develop hypotheses regarding the ancestry of the five species. Although these exercises were designed to supplement and enhance classroom instruction on phylogeny, cladistics, and systematics in the context of a postsecondary majors-level introductory biology course, the activities themselves require very little prior student exposure to these topics. Thus, they are well suited for students in a wide range of educational levels, including a biology class at the secondary level. In implementing this exercise, we have observed measurable gains, both in student comprehension of molecular phylogeny and in their acceptance of modern evolutionary theory. By engaging students in modern phylogenetic activities, these students better understood how biologists are currently using molecular data to develop a more complete picture of the shared ancestry of all living things. 相似文献

We explored the effectiveness of distance learning and multimedia technologies in facilitating an expanded learning community
among two teachers and their students in geographically separated schools. The teachers collaboratively developed curricular
activities and identity-forming multicultural activities for their K-12 students to conduct over the distance. Predominantly
Hispanic students in a school on the Texas border with Mexico communicated regularly over a school year with diverse students
in a partner school hundreds of miles to the north. They participated in collaborative activities and shared multimedia files
via interactive videoconference. Using qualitative research methods, we discovered that the participating teachers developed
empowering multicultural relationships while their students developed multicultural understanding and positive self-concept.
Examples of empowerment and positive self-concept included raised levels of academic aspirations and heightened poise during
public speaking.

We report on the design, development, implementation, and evaluation of a case-based instructional environment designed for
learning network engineering skills for cybersecurity. We describe the societal problem addressed, the theory-based solution,
and the preliminary testing and evaluation of that solution. We identify an architecture for scaffolding case-based learning
for problem-solving to inform design of case-based learning environments. 相似文献

We studied the conceptions of students coming from secondary education and university regarding the number line as a representation of real numbers. In the context of a wider questionnaire, 307 students were presented with a task consisting of two verbal items and one graphic item related to the number line. The students were all at different levels in their study of mathematics (in the third, fourth or fifth year of secondary education, or at the beginning or advanced stage of a university degree in mathematics, biology or physical education). A gradient in the depth of the students’ conceptions, associated with the level of their studies in mathematics, was found. This gradient extends from the estrangement of facing the problem or a conception of a drawn or physical matter line, which was associated with students with a lower level of mathematical studies, passing through a vision centred around potential numeric density or a line containing points (discrete), up to an instrumental conception of the line as supportive of magnitudes in advanced students of biology and focusing on continuity sustained by advanced students of mathematics. 相似文献

We report on an investigation into the design, development, implementation, and evaluation of an informational and instructional
Website in order to generate guidelines for instructional designers of read/write Web environments. We describe the process
of design and development research, the problem addressed, the theory-based solution, and the evaluation and testing of that
solution. Based on our experience, we then identify sixteen guidelines for future designers and developers of read/write Web-based
learning environments. The study demonstrates how read/write Web technologies can be used to address general problems that
have intrinsic societal importance; examines implementation of a read/write technology in a real-life context, thereby testing
distributed cognitions learning theory; informs the design of similar environments; and provides grounded theory for the design
and development of read/write Web learning environments. 相似文献
