A problematic, yet common, assumption among educational researchers is that when teachers provide authentic, problem-based experiences, students will automatically be engaged. Evidence indicates that this is often not the case. In this article, we discuss (a) problems with ignoring motivation in the design of learning environments, (b) problem-based learning and scaffolding as one way to help, (c) how scaffolding has strayed from what was originally equal parts motivational and cognitive support, and (d) a conceptual framework for the design of scaffolds that can enhance motivation as well as cognitive outcomes. We propose guidelines for the design of computer-based scaffolds to promote motivation and engagement while students are solving authentic problems. Remaining questions and suggestions for future research are then discussed. 相似文献

Wilson et al.'s (1998) revision of politeness theory has been applied to requesting, refusing and relational development, finding that different types of face threat are present in an interaction depending on the interaction goals. This investigation seeks to extend Wilson et al.'s (1998) work by determining how threats to a speaker's and hearer's face needs influence a requester's desire to persist and use of persuasion and forgiving statements after refusal. Results indicate that refusals creating greater threat to the positive and negative face needs of requesters yield greater desire to persist and use of persuasion statements. Specific face threats did not appear to be related to use of forgiving statements. 相似文献

A series of studies present the development and validation of the Communication Anxiety Regulation Scale (CARS), a self-report measure designed to assess the use of emotion regulation strategies to manage acute communication anxiety—in contrast to measures of general emotion regulation tendencies. Study 1 delineates the item derivation and selection process that yielded the final 12 CARS items. Results of an exploratory factor analysis supported the existence of four distinct subscales, each representing one of four anxiety regulation strategies (suppression, reappraisal, avoidance, and venting). Study 2 confirmed this factor structure and also examined correlations of the CARS with existing measures in an attempt to establish concurrent validity. Finally, Study 3 presents results of an item-sort task demonstrating the scale’s face validity and items’ substantive validity. Overall, findings provide preliminary support for the utility of the CARS as measure of communication anxiety regulation to be used by communication and psychology researchers. 相似文献

One of the key characteristics of effective opinion leaders is that they are highly connected; they know many people and have numerous weak-tie relationships. Two studies were conducted that found evidence consistent with construct validity. The first (N = 35 and N = 57) found that connectors knew more people from a randomly selected list of names. A second study, with two surveys, was created (N = 561 and N = 189) such that the connectedness scores of some of the subjects in the first survey could be linked to how many subjects knew them in the second. Results indicated that those with higher connection scores were more likely to be known by others. Moreover, in the second survey, measures of Facebook use and bridging social capital were found to be associated substantially with connector scores. 相似文献

The explosive growth of Internet and E‐mail use has provided exceptional opportunities for humans to mediate their communication and thus their relationships in new ways. This study reports on a content analysis of interrogative strategies used in E‐mail messages exchanged over six months between intergenerational sets of senior citizens and youngsters. A great deal of relationship development is facilitated by the use of questions which are a core aspect of uncertainty reduction processes. While Uncertainty Reduction Theory (URT) has been a predominant theoretical position for examining face‐to‐face initial interaction, its utility for examining communication in an asynchronous, computer‐mediated environment was only partially effective. Data analyses focused on politeness of questions, types of questions, and, temporal effects. Results suggest that the interrogative strategies we engage in to achieve interpersonal connectedness are sometimes different in computer‐mediated communication (CMC) and a new standard for transacting relational message exhange may be emerging. 相似文献

This essay examines one of the most intractable pedagogical problems of the Marxian revolutionary tradition: who will educate the educator and how ought the learning process to proceed. The solutions of Marx, Lenin and Habermas are critically examined towards the clarification of the emancipatory learning process. This learning process has three components: enlightenment, empowerment and emancipatory collective action. Lessons are drawn for our own time. 相似文献
