Exploring the music: a teaching-learning sequence about sound in authentic settings

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.     

The Role of Artists in Sites for Learning

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.     

Applying Gadamer’s concept of disposition to science and science 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.     

From school to higher education in Australia

This paper addresses the question of why young people go on from school to higher education in Australia. A person-situation interactionist theory to explain decisions taken in the matter is developed, and in the light of this theory a model to predict entry to higher education is advanced. The model is tested using data from separate studies in two Australian States, Victoria and Queensland. Results of bivariate and logistic regression analyses are generally consistent with expectations from the model. Certain interactive effects of variables in the model upon entry to higher education are reported.     

Measuring experiences of interest-related pursuits in connected learning

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.     

The Effects of Teacher Professional Development on Children’s Attendance in Preschool

Abstract

Student 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.     

Cortisol in Neonatal Mother's Milk Predicts Later Infant Social and Cognitive Functioning in Rhesus Monkeys

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.     

Adult Learner Participation in an Online Degree Program: A program‐level study of voluntary computer‐mediated communication

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.     

Relative Effects of a Comprehensive Versus Reduced Training for Head Start Teachers Who Serve Spanish-Speaking English Learners

With increased demand for improved early childhood education services, it is important to better understand the essential professional development resources that have the greatest impact on both teacher and child outcomes. This study compared the effectiveness of two teacher-training models in bilingual Migrant and Seasonal Head Start and Head Start classrooms. Both conditions included the use of a technology-based student progress-monitoring tool. The progress monitoring provided detailed feedback on students’ progress 15 across the academic year and helped organize instructional groupings. The comprehensive treatment condition included biweekly professional development sessions, in-class mentoring, and provision of classroom materials, whereas the treatment-control condition included only the provision of a limited set of classroom materials. Across multiple sites in Texas, 49 pretest and posttest teacher observations and bilingual child assessments were collected on a subsample of students (n = 387). Research Findings: Improvements in teaching behaviors were observed in both experimental conditions; no significant differences were observed between teachers across conditions. Three measures of child language and literacy growth differed significantly, favoring the comprehensive treatment model, but most outcomes did not differ significantly between groups. Practice or Policy: Implications of these mixed findings and future research directions are discussed.
