Unilateral enterprise resource planning (ERP) curriculum improvements from the instructor's perspective are likely to generate only limited success. Understanding student motivations and beliefs with ERP systems is the missing link to effective ERP education. Relatively little attention in the ERP literature has been given to student learning associated with ERP experience, and almost none to factors influencing current and expected student beliefs and behaviors relative to ERP. The complexity of ERP systems demands that beliefs and behaviors be considered when planning ERP curricula. In the present study, the Theory of Planned Behavior was extended to examine students’ intentions to explore additional aspects of ERP after their class exercises. When considering all students, attitude and subjective norm had positive and significant effects on intentions to continue ERP learning. Subjective norm also affected attitude, and availability of support materials had a positive effect on subjective norm. Distinctive patterns are found for the construct relationships between student groups who valued ERP education (the engaged) and those who placed little or no value on ERP education (the undecided). Results from competing model analyses indicate that support materials influenced the engaged and undecided groups differently. Strategies for ERP curriculum design are provided.  相似文献

The rationale was to apply Piaget’s theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of identical objects or pairs of objects similar only in volume vs. pairs of objects which differed in volume. It was concluded that squirrel monkeys have the prerequisite skills for the conservation of quantity. Discussion included methodological problems associated with demonstrating conservation in nonhumans as well as the potential usefulness of Piaget’s theory for phylogenetic studies of intelligence.  相似文献

We examined the implementation of a laser-disk based science curriculum in an elementary school. The goal was to develop a richer understanding of the principles for designing a curriculum that will adequately support teachers in adopting a learner-centered framework. Issues included: who has ownership of the classroom discussion; what types of activities are engaged in terms of the constraints imposed; and what is the teacher's response to the specific tools provided (the teacher's guide, the Circle of Learning, and concept maps). In addition to looking at the implementation pattern, we also examined the impact of the implementation on student attitudes and anxiety toward science. Results indicated little adoption of the curriculum, and teachers continued to maintain a high degree of control in the classroom. However, results also indicated significant effects of the curriculum on science attitude and anxiety. Suggestions for future research are included.  相似文献

Recent research into composing processes has focused on instructional intervention strategies that promote effective composition practices within computerized writing environments. The field of computers and composition has benefitted both from advances in computing tools and developments in learning theory. The innovative computer tool discussed in this paper uses the macro-command language of a full-featured word processor to enact strategic support designed to help writers with their written work. From a theoretical standpoint, this tool created a writing environment based on Vygotskian theory of mediated learning and was grounded in an instructional strategy known as “procedural facilitation.” To evaluate the effectiveness of this computerprompting tool, a second macro application was used to log student keystrokes, thereby tracking student writing development, revisionary practices, and keystroke reactions to the prompting partner. Students using the prompting tool enacted divergent and convergent thinking assistance that appeared at the bottom of their computer screens while the system saved a process record of their keystrokes. Procedures for creating macro-driven prompting programs and keystroke-logging devices are discussed. Additionally, a catalog of prompts and summary of keystroke-mapping benefits are provided. Finally, our research using the macro-driven prompting partner and keystroke-register tool is detailed.  相似文献

The nexus between college choice and persistence   总被引:2,自引:3,他引:2  
Initial student commitments have long been considered an influence on persistence, but the reasons why students choose to attend a college have seldom been considered as dimensions of initial commitments that could influence persistence processes and outcomes. This study used NPSAS-87 to examine the influence of finance-related reasons for choosing a college on persistence decisions. The findings include (1) finance-related choices have direct and indirect influences on whether students persist in college; and (2) market-based, monetary measures of financial aid, tuition costs, housing costs, and other living costs have a substantial direct effect on persistence.  相似文献
