Background: Research regarding students’ ideas about the nature of sound reveals a variety of conceptions about sound. In order to reconstruct these ideas and explain sound phenomena, researchers’ teaching interventions often make use of everyday-life contexts. However existing research on sound only partially addresses the correlation between the properties of sound and its perceptive characteristics.
Purpose: To identify the evolution of students’ conceptions regarding the nature of sound and its properties (frequency, intensity and frequency spectrum) through a teaching-learning sequence (TLS) about sound phenomena in an authentic musical context. The described TLS consists of three activities aiming students to correlate the properties of sound waves (frequency, intensity and frequency spectrum) with its perceptive characteristics (pitch, loudness and timbre) via the use of smartphone applications.
Sample: Eight students, in the second year of their studies in the Department of Primary Education of the XXX University.
Design and methods: Students’ perspectives on sound and their progression are investigated through a teaching experiment design. Data are collected by recording students’ interviews. Due to the explorative nature of the research qualitative methods of content analysis are used.
Results: The results show that the students’ perspectives on sound evolved, as students managed to consolidate links between their everyday experience of sounds and the underlying science concepts as frequency, intensity and frequency spectrum. The authentic environment and the use of the smartphone’s applications were key factors for the success of the teaching experiment. The interaction with the activities shifted student’s conceptualizations closer to the scientific ones, by communicating every day sound experiences with their scientific interpretation. 相似文献
This project explored how iPads were being used in a range of K‐12 schools to support the learning of students with a range of learning support needs. Groups of teachers (and other professionals) from the USA, Canada, Australia and the UK were invited to complete an online survey focused on the use of iPads in their classrooms, perspectives of their skill level, and how their school and school districts support the use of iPads. The survey focused on iPad use in classrooms (curriculum and skills); teachers’ skill levels; whether iPads are addressed in the Individualised Education Program (IEP); the systemic support for the iPads; and the perceived benefits and barriers. The results reveal that respondents are using iPads across many areas of the curriculum, which affirms the research in the emerging literature base. However, there are teacher reported differences in the manner and scope of iPad use in the classrooms and also the integration of the iPad in the IEP. The research also highlights variability in reported skill level for the iPad and an increased need for enhanced systemic support, such as training, funding, technical support and administrative support for the use of the iPad as a pedagogical tool. 相似文献
Socially engaged, participatory and educational arts activities have been recognised by artists as a legitimate area of creative practice for a considerable time. Current policy initiatives around social inclusion and life long learning demonstrate that this government has a keen interest in the transformative nature of creativity and participation in arts activity. This paper explores the significance of the, Arts Council's Artists in Sites for Learning Scheme and a related piece of research within the context of recent cultural agendas and governmental policy initiatives. The research examined the ‘forms of engagement’ that occur between artists, participants and others and concludes that the role the artist inhabits within this form of creative practice is multifaceted and highly sophisticated. This paper also raises key issues concerning the ‘value’ and critical assessment of this form of practice and the need for appropriate support for (and evaluation of) it in the future. 相似文献
Promoting students’ ability to transfer or apply their knowledge and skills to real-life situations is critical in higher education. The current study was designed to test the likelihood that the constructs based on self-determination theory (SDT) framework help understand college students’ perceived knowledge transferability. A total of 3783 undergraduates from 301 classes participated in this study. The results of a series of multilevel modeling analyses indicated that (a) competence satisfaction and identification were the most salient factors influencing students’ perceived knowledge transferability; (b) the SDT-related variables together explained 64.2% of the between-student variance in perceived knowledge transferability; (c) after controlling for student-level covariates and SDT-related variables, 7.9% of the variance in perceived knowledge transferability was caused by between-class differences, and 19.6% of it could be explained by course fields and course levels. Our results, which provide evidence of multilevel factors influencing college students’ perceived knowledge transferability, have implications for promoting transfer in higher education.
In this paper, I recall previous arguments for a hermeneutic approach to science and claim that such an approach necessitates attention to the development of dispositions. I undertake an analysis of Hans-Georg Gadamer’s philosophical hermeneutics to identify and describe dispositions relevant to a hermeneutic approach to science. I then apply elements of Gadamer’s theory of education to the problem of fostering appropriate dispositions in science classrooms. In doing so, I offer a few suggestions for the cultivation and assessment of these dispositions in K-12 and college classrooms. 相似文献
This paper describes an effort to develop a survey instrument capable of measuring important aspects of adolescents’ experiences of interest-related pursuits that are supported by technology. The measure focuses on youths’ experiences of connected learning (Ito et al. in Connected learning: an agenda for research and design. Digital Media and Learning Research Hub, Irvine, 2013), an emerging model of learning across settings supported by digital media. Specifically, the instrument aims to measure the depth with which youth are able to engage in an interest-related pursuit, the level of support and encouragement they receive from peers, and the degree to which their pursuit involves performance or media production as an essential feature. The survey also elicits information regarding the connections between youths’ interest-related pursuits and academic goals, the involvement of adults as co-participants in pursuits, and youths’ access to technology tools they deem necessary for their pursuits. The paper reports on results from a pilot study and two rounds of field-testing, in which we evaluated the validity and reliability of the instrument and compared results with evidence from interviews with youth. Our aim was to investigate the feasibility of an approach to measuring youths’ interest-related pursuits to inform future research and evaluation of initiatives focused on digital media and learning. 相似文献
AbstractStudent absenteeism is a widespread and critical issue in early childhood education. Current efforts to reduce student absenteeism in both preschool and K–12 settings have largely been family- and parent-focused interventions. Yet, interventions targeting teachers and schools may similarly be effective tools to improve student attendance. We utilize data from a large-scale, experimental evaluation of an early childhood professional development intervention to examine whether it impacted children’s absenteeism and chronic absenteeism. Although the professional development targeted the quality of teacher-child interactions and did not target children’s absenteeism, we find that the professional development reduced student absence rates by 1.0 percentage points (equivalent to approximately an additional 1.9?days of preschool). The professional development also reduced chronic absenteeism by 6.0 percentage points. Impacts were concentrated among lower-income children. Implications for policies targeting student absenteeism in preschool settings are discussed. 相似文献
Milk provides not only the building blocks for somatic development but also the hormonal signals that contribute to the biopsychological organization of the infant. Among mammals, glucocorticoids (GCs) in mother's milk have been associated with infant temperament. This study extended prior work to investigate rhesus monkey (Macaca mulatta) mother–infant dyads (N = 34) from birth through 8 months postpartum. Regression analysis revealed that cortisol concentrations in milk during the neonatal period predicted impulsivity on a cognitive task, but not global social behaviors, months later. During this time period, sex‐differentiated social behavior emerged. For female infants, milk cortisol concentrations predicted total frequency of play. Collectively, these findings support and extend the “lactational programming” hypothesis on the impact of maternal‐origin hormones ingested via milk. 相似文献
Quality teacher-child interactions are characteristic of effective classrooms resulting in benefits for all children, but may be particularly important for children from low-income families. The purpose of this study was to explore the perception of Illinois Head Start teachers related to how I am Moving, I am Learning (IMIL) could improve the quality of their instruction as measured by the Classroom assessment scoring system (CLASS®), an observation instrument used to assess the quality of teacher-child interactions across three broad domains and their supporting dimensions. While the study found that early childhood professionals perceive IMIL as a meaningful resource, additional research is needed to substantiate the preliminary findings as well as to guide training initiatives that would help Head Start professionals to make the connection between IMIL and the CLASS®. 相似文献
Several studies examining computer‐mediated communications (CMC) in online courses have found low levels of participation under both voluntary (ungraded) and mandatory (graded) conditions. This is troubling since student participation is widely considered to have a positive impact on performance. Program‐level data were analyzed to explore the relationship between three factors—(1) experience with previous online courses, (2) the course itself, and (3) the instructor—and subsequent participation. All three factors separately impacted participation levels in this voluntary CMC setting. Based on the findings, the authors recommend that researchers using CMC participation level as a study variable consider controlling for three global factors: previous online course experience, course, and instructor. Finally, the relationship between participation level and subsequent performance is tested, and the potential benefits of conducting future CMC research in voluntary discussion settings and with program‐level data are discussed. 相似文献
