Academic music: music instruction to engage third-grade students in learning basic fraction concepts
Susan Joan Courey Endre Balogh Jody Rebecca Siker Jae Paik 《Educational Studies in Mathematics》2012,81(2):251-278
This study examined the effects of an academic music intervention on conceptual understanding of music notation, fraction symbols, fraction size, and equivalency of third graders from a multicultural, mixed socio-economic public school setting. Students (N?=?67) were assigned by class to their general education mathematics program or to receive academic music instruction two times/week, 45?min/session, for 6?weeks. Academic music students used their conceptual understanding of music and fraction concepts to inform their solutions to fraction computation problems. Linear regression and t tests revealed statistically significant differences between experimental and comparison students?? music and fraction concepts, and fraction computation at posttest with large effect sizes. Students who came to instruction with less fraction knowledge responded well to instruction and produced posttest scores similar to their higher achieving peers. 相似文献

The 60th anniversary of the Bandung Conference adopted the Bandung Message 2015, suggesting Asia and Africa be committed to eradicating poverty, narrowing the gap in living standards, and fostering closer cooperation across the regions. Whilst the historic 1955 Bandung Conference can be understood as a reaction to the Cold War system in the form of an alternative framework for cooperation among nations that resisted the hegemony of economic and military alliances dominated by specific countries, present day Asia witnesses significant attempts to reshuffle the world order; such as the Asia-Pacific system and China's “One Belt One Road” project. Equally, there are also signs of a determination towards openness and to cross boundaries in a spatial sense that may lead to the reshuffling of both institutions and everyday lives. These attempts are aimed at realizing a different Asia and a different world, rather than becoming part of a world order led by a specific country. The “people” of Asia have experienced colonization and forced emigration, drifting around the region while, at the same time, fleeing from one place to another, resulting in numerous interactions with diverse social systems and cultures. In this process they have shaped new spaces, places and social relations within the shifting landscapes of imperialism, the Cold War and globalization. These could be defined as a “historicized Asia” in which various movements, ruptures and hostilities generated by imperialism and the Cold War overlap, but at the same time crystallize the reality of Asia in the era of globalized capitalism. In this context, it is important to explore the way Asia is being constructed within the everyday lives of people as well as from the top; to focus on a different Asia that sits outside modern constructions of ethnicity and nation state, and to locate Asia in the context of its relationship with Africa and Latin America in this historic moment of the 60th anniversary of the Bandung Conference. Therefore, this is the time we may need to question whether or not “Asians in Asia are still alive and well.” 相似文献

This study investigates the various conceptions held by K‐8th Korean grade students regarding the ‘changes of state’ and the ‘conditions for changes of state’. The study used a sample of five kindergarteners, five secondgrade students, five fourth‐grade students, five sixth‐grade students, and five eighth‐grade students. The 25 students attend schools in a rural district of South Korea. Some activities that involved a change in the state of water, including condensation, solidification, and melting, were chosen from K‐8th grade science textbooks and attempted by the students. Subsequently, we conducted interviews with the students. While most kindergarteners and second‐grade students were able to perceive the phenomena involving changes of state, they were unable to express conceptions related to the changes of state and the conditions under which the state the changes. The upper‐grade students, on the other hand, had some conception of the invisible gas state. Most of these students held conceptions about the boiling water's change of state from liquid to gas, but few of them held conceptions about the changes of state involving condensation. Most students understood heat and temperature as conditions of the changes of state, but only applied the heat concept to situations involving rising temperatures. In situations involving cooling, students applied the temperature concept. The younger students understood the concept of heat without understanding the concept of temperature. 相似文献

Antioxidative and cytotoxic effects of chamomile (Matricaria chamomilla) fermented by Lactobacillus plantarum were investigated to improve their biofunctional activities. Total polyphenol (TP) content was measured by the Folin-Denis method, and the antioxidant activities were assessed by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and β-carotene bleaching method. AGS, HeLa, LoVo, MCF-7, and MRC-5 (normal) cells were used to examine the cytotoxic effects by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. The TP content of fermented chamomile reduced from 21.75 to 18.76 mg gallic acid equivalent (mg GAE)/g, but the DPPH radical capturing activity of fermented chamomile was found to be 11.1% higher than that of nonfermented chamomile after 72 h of fermentation. Following the β-carotene bleaching, the antioxidative effect decreased because of a reduction in pH during fermentation. Additionally, chamomile fermented for 72 h showed a cytotoxic effect of about 95% against cancer cells at 12.7 mg solid/ml of broth, but MRC-5 cells were significantly less sensitive against fermented chamomile samples. These results suggest that the fermentation of chamomile could be applied to develop natural antioxidative and anticancer products. 相似文献

Since A Nation at Risk was released in the 1980s, standards-based reform has been the most dominant trend in American educational policy, and the
No Child Left Behind Act pushed the trend further by requiring states to develop rigorous curriculum standards. Though much
has been said about these new standards, less has been said about whether or how well professional development helps teachers
link their instruction to these standards. This study examined the impact of a professional development program for K-12 science
teachers in helping teachers meet state curriculum standards. Seventy-five science teachers in Michigan participated in a
2-week summer workshop that used Problem-Based Learning for improving teachers’ content knowledge and pedagogical content
knowledge. Researchers surveyed participating teachers about the change of teachers’ preparedness for standards-based teaching,
their expectations to meet state curriculum standards, and whether their expectations were met. In addition, the usefulness
of workshop activities was examined. Data analysis showed that to align teaching with state curriculum standards, participating
teachers expected to learn instructional strategies and enhance science content knowledge through professional development,
and by and large their expectations were well met. Collaboration with colleagues and facilitators helped teachers achieve
their goals in terms of teaching within state curriculum standards. These findings have important implications for designing
professional development to help teachers align instruction with curriculum standards. 相似文献

A national survey of 53 early childhood special education teachers in Korea was conducted to investigate their knowledge and perceptions regarding various aspects of kindergarten and preschool programs for children with disabilities. Results from the study indicated that (a) children in the age range of 3 to 7 years were the group most frequently served by early childhood special education in Korea, (b) teachers reported infrequent assessment and scarcity of curriculum resources, (c) most teachers reported using a self- or school-developed curriculum, and (d) confusion exists regarding the concept and use of the Individualised Education Program (IEP). Because of a somewhat lower than expected teacher response rate further study is needed to determine if the results of this study are representative of programs nationally. Also, evaluative steps should be taken to ensure that curricula are appropriate for the various ages and types of learners. Likewise, research is needed to identify those factors that facilitate inclusion of children with disabilities in their schools and communities with peers as early childhood special education programs expand. 相似文献

It is essential for dental hygienists to have basic knowledge of gross anatomy to provide efficient treatment. However, gross anatomy course is relatively neglected due to their disparity from actual clinical dental practice. This study aimed to propose an effective dental hygiene gross anatomy curriculum that reflects the opinions of professional clinical dental hygienists. The study had an online-based cross-sectional design and the survey was distributed to clinical dental hygienists via social networks (n = 200). The questionnaire consisted of questions on the utilization of anatomical knowledge in clinical practice, opinions on the contents and methods of gross anatomy education, and general characteristics. The present study found that 186 (93%) used anatomical knowledge at an above-average level. Qualitative analysis indicated that dental implant surgery, radiography, and extraction were the clinical procedures that required the most anatomical knowledge. The clinical dental hygienists answered that the most-necessary knowledge is that of the mandibular nerve, followed by that on the temporomandibular joint, mandible, maxilla, maxillary nerve, and masticatory muscle. The methods proposed to improve gross anatomy education were (in decreasing order of importance) using videos or photographs (X-rays, CT, MRI, etc.), integrating education with clinical subjects, and using a three-dimensional visualization program. Higher education levels of respondents have increased their tendency to believe that the contents and methods of the presented education were necessary. Dental hygienists who utilized anatomical knowledge more often tended to be had a greater appreciation of the necessity of all educational contents and methods. 相似文献
