Using data from the College Student Experience Questionnaire research program between 1998 and 2004, this study examined the effects of student engagement in inquiry-oriented activities on a range of self-reported college outcomes. The results indicate that (1) engaging in inquiry-oriented activities has significant and positive effects on a global measure of gains; (2) engagement has positive effects on some college outcomes but negative effects on others; (3) the effects of inquiry-oriented activities are conditional, with some students benefiting more than others. This study reveals the complexity of the influences of inquiry-oriented activities on college students and points to implications for institutional policies and programs that may be effective in fostering desired college outcomes.

Eighteen Long-Evans rats were exposed to a MULT VT 30-sec EXT schedule of water presentations. The EXT schedule was signaled by a 2500-Hz, 70-dB tone. Mean number of bites of a plastic target during atone (S?) increased across sessions, whereas the mean number of target bites during the VT component signaled byno tone (S+) decreased across sessions. Changing the multiple schedule to MULT EXT EXT produced a decrease in target bites during the tone. Reinstating the original MULT VT 30-sec EXT schedule produced an increase in number of target bites during the tone (S?). Changing the multiple schedule to VT 30-sec VT 30-sec produced a decrease in target bites during the tone. The results indicate that target biting in rats increases in the presence of the exteroceptive tone (S?) of the MULT VT 30-sec EXT schedule, and that target biting during the tone varies directly with the negative correlation between tone and water presentations.  相似文献

树立科学的教育均衡发展观   总被引:8,自引:0,他引:8  
树立科学的教育均衡发展观,对于保证教育事业健康发展至关重要。推进教育均衡发展,要深刻认识教育均衡发展的基本内涵,树立以人为本的教育均衡发展观,准确把握教育均衡发展的层次性,正确理解教育均衡发展的阶段性;要正视教育供给与教育需求的长期矛盾,认识导致教育发展不均衡的制度缺陷,警惕教育发展中的"低水平"和"高水平"均衡陷阱,了解我国社会教育流动的新特点;要把握教育均衡发展的关键问题,坚持全面协调可持续的教育均衡发展观,重点推进区域教育均衡发展,建立和完善教育均衡发展保障体系。  相似文献

It was demonstrated that an odor presented to rats in a distinctive environment can interfere with toxicosis-based conditioning to the environmental cues. Rats poisoned when they drank unflavored water in a black compartment odorized with oil of eucalyptus exhibited no suppression of water intake when they were subsequently tested in the same compartment minus the odor. In contrast, rats poisoned in the same compartment minus the odor later exhibited reduced water consumption in that environment. Oil of eucalyptus proved to be as effective an overshadowing stimulus as a taste cue (a 1.5% NaCl solution).  相似文献

We describe the benefits and challenges of engaging in public data mining methods and situate our discussion in the context of studies that we have conducted. Practical, methodological, and scholarly benefits include the ability to access large amounts of data, randomize data, conduct both quantitative and qualitative analyses, connect educational issues with broader issues of concern, identify subgroups/subpopulations of interest, and avoid many biases. Technical, methodological, professional, and ethical issues that arise by engaging in public data mining methods include the need for multifaceted expertise and rigor, focused research questions and determining meaning, and performative and contextual considerations of public data. As the scientific complexity facing research in instructional design, educational technology, and online learning is expanding, it is necessary to better prepare students and scholars in our field to engage with emerging research methodologies.  相似文献
