Three budgerigars were trained with operant techniques to discriminate examples of species-specific contact calls. Once the birds learned the discrimination among a large set of calls, they were tested with the calls altered in various ways. The birds’ performance on altered calls was compared with performance on normal calls. Results show that the birds could tolerate large spectral and temporal alterations in the calls with little or no decrement in performance. A comparison of the birds’ performance across conditions shows clear evidence of a redundancy in information contained in the calls. The birds were equally adept at discriminating among the calls when given only high-frequency information and when given only low-frequency information. The birds also performed just as well when presented with only the short beginning portions of the calls as they did when presented with somewhat longer portions near the end of the calls. This ability of budgerigars to discriminate among species-specific vocal signals that are highly distorted is reminiscent of the ability of humans to discriminate and recognize highly distorted speech sounds. 相似文献

The current popularity of flipped learning may be attributed to its reported successes in bringing about enhanced learner engagement and positive learning outcomes. This study aims to improve our understanding of flipped learning (FL) outcomes by examining factors of learner engagement, academic capability, and epistemological beliefs. Data were collected and statistically analyzed from 231 undergraduate students enrolled in a general biology or general chemistry course at a Korean university implemented with the FL model. The results indicated that learners’ epistemological beliefs influenced neither pre-class nor in-class engagement, but that academic capability did affect both pre-class and in-class engagement. Only content/learning-related outcomes, not generic competencies or satisfaction, were affected by both academic capability and epistemological beliefs. Both pre-class and in-class engagement levels affected most types of FL outcomes except generic competencies, which were only affected by the extent of in-class engagement. Learners’ affective engagement was not influenced by epistemological beliefs, but directly and indirectly affected FL outcomes via behavioral and cognitive engagement. Theoretical and practical implications are discussed along with recommendations. 相似文献

This study compares the views of teachers and professional development facilitators about effective professional development
(PD). We analyzed interviews with 72 teacher participants and 23 PD facilitators involved in nine science and mathematics
PD projects. The teachers' themes for characterizing effective PD included classroom application, teacher as learner, and
teacher networking. Similarly, the PD facilitators discussed effective PD as having classroom application and experiences
for teachers as learners. In addition, PD facilitators shared the need to develop collegial relationships with teachers and
improve teacher knowledge. These views correspond to some of the standards and recommendations described in policy and research
documents on effective PD. Criteria of effective PD in these documents that the participants did not mention included: (1)
challenging teachers' content and pedagogical content knowledge with transformative learning experiences, (2) encouraging
teacher leadership for sustained support, and (3) focusing on student learning by instructing teachers on how to use student
data to inform their teaching practice. Our findings have implications for designing PD that reflects the criteria of standards-based
reform. 相似文献

The authors' purpose was to examine the degree to which low achievement is related to ontogenetic factors (i.e., personal psychological traits expressed as attention and depression) or microsystemic factors (i.e., socioeconomic status, parenting, relationship with peers and teachers), using a total of 721 middle school students in South Korea. Based on the percentile rank, low-achieving students (bottom 15%; n = 323) and high-achieving students (top 15%; n = 398) were grouped, and a multigroup structural equation modeling was employed to determine which ecological factor(s) contribute to predict low achievement of middle school students. Results from multigroup structural equation modeling showed that 3 of the 6 ecological and ontological factors had significant direct or indirect effect on low achievement: socioeconomic status (direct effect), attention (direct effect), parenting (indirect effect). The findings are discussed in terms of the intertwined influences of ecological factors on low achievement, finally leading to the discussion on the limitations and future directions for research. 相似文献

The goal of this research effort is to provide insights on what core needs and difficulties exist toward the implementation
of ICT in higher education in emerging countries and how a consortium like LINC can best support these efforts. An exploratory
research design combining a survey, on-site interviews, participant observation and document analysis were employed to answer
the research questions. Main challenges in establishing technology- based learning environments were identified in the area
of pedagogies, finances, technological infrastructure, cultural change, organization, and management. LINC, as an non-political
organization embedded in an academic environment, can take an important role in facilitating the dialogue among participants
through various platforms, take an active role in promoting joint programs and assist with efforts to “localize” tools and
practice.

Education and poverty in rural China 总被引:3,自引:0,他引:3
We analyze household and school survey data from poor counties in six Chinese provinces to examine the effects of poverty, intra-household decision-making, and school quality on educational investments (enrollment decisions) and learning outcomes (test scores and grade promotion). Unlike previous studies, we use direct measures of credit limits and women's empowerment. Drawing a distinction between the effects of wealth (measured by expenditures per capita) and credit constraints, we find that the former improves learning while the latter reduces educational investments. We find evidence of a story of gender bias in which academically weak girls are more likely to drop out in primary school while most boys continue on to junior secondary school. Women's empowerment reduces the likelihood of dropping out but does not affect other outcomes. Finally, our measures of school quality have some effect on the duration of primary school enrollment but not on learning. 相似文献

Children's representations of conflict and distress situations at 7 years were examined as developmental precursors to relational aggression, overt aggression, and psychiatric symptoms in early adolescence. Children were identified in early adolescence. Children were identified in preschool as normally developing or with behavior problems. Overt, but not relational, aggression, was correlated with concurrent disruptive symptoms in adolescence. Childhood predictors of adolescent aggression were found only for girls: Early hostile themes predicted more relational and overt aggression, while prosocial themes predicted less relational aggression. Also for girls only, early emotions foretold later functioning: Sadness predicted a higher ratio of relational to overt aggression, while inexpressiveness predicted disruptive, anxiety, and depressive symptoms. Relational and overt aggression are discussed with regard to sex differences in symptom changes over time. 相似文献

This study investigated the effectiveness of e-learning by comparing the learning outcomes in conventional face-to-face lectures and e-learning methods. Two video-based e-learning contents were developed based on the rapid prototyping model and loaded onto the learning management system (LMS), which was available at http://www.greenehrd.com. Eighty-five Korean agricultural high school students were randomly assigned into the two groups: face-to-face lecture (control group), and video-based e-learning (experimental group). The students of the experimental group logged onto the LMS in the school computer lab and completed each e-learning module. All students were required to take a pretest and posttest before and after learning under the direction of the subject teachers. One-way analysis of variance (ANOVA) was used to examine any difference between the two groups in terms of learning outcomes. One-way analysis of covariance (ANCOVA) was also administered to verify whether there was any difference between the two groups after controlling for the covariate variable: pretest score. According to the results, e-learning resulted in better learning outcomes than face-to-face lecturing. These findings suggest that the use of well designed and appropriately applied e-learning could be worthy even in agricultural education, which stresses hands-on experience and lab activities. Further research should focus on a different e-learning content type in different agricultural subject fields and its relationship with learning outcome. 相似文献
