Making learning last: teachers’ long-term retention of improved nature of science conceptions and instructional rationales

ABSTRACT

Despite successful attempts to improve learners’ nature of science (NOS) conceptions through explicit, reflective approaches, retention of improved conceptions is rarely addressed in research. The issue of context for NOS instruction has implications for this retention. Whether to contextualise has been the question occupying science educators’ attention. We think this question is misplaced. Instead, we build upon recent research addressing a context continuum – drawing on the strengths of both contextualised and noncontextualised NOS instruction – to improve retention. Although there are many different potential contexts for NOS instruction, this investigation focuses on science content as context. The present investigation focused on long-term retention of improved NOS conceptions and rationales for NOS instruction. Participants were all 25 teachers who completed a professional development programme (PDP) utilising a mixed contextualisation approach to NOS instruction. We classified teachers’ NOS conceptions into three levels of understanding using the Views of the Nature of Science Form-C responses and interviews three times over the year: pre-, post-, and 10-month delayed post-PDP. Results indicated that initially participants held many alternative NOS conceptions. Post-instruction, responses were substantially improved across all NOS concepts. Furthermore, nearly all of the participants’ conceptions were retained across the academic year following the PDP. Participants offered varied rationales for NOS instruction including its potential to improve students’ scientific literacy, perceptions of the relevance of science, improve positive risk-taking, and increase tolerance for differences. These results contrast favourably with previous reports of the retention of improvements in NOS conceptions over time.     

Reliability and Preliminary Use of a Rubric to Assess Pre-Kindergarten Teachers’ Video Uses

The presence and use of new technologies in early childhood settings are rapidly increasing. One technology tool used in early childhood settings is monthly DVD classroom newsletters, yet there is a lack of assessments to support pre-kindergarten teachers’ uses of such DVD newsletter technology—in general and in specific. The present study helps to fill this gap by developing and testing a revised rubric to evaluate the quality of monthly DVD classroom newsletters. Results indicate that the revised Monthly DVD Classroom Newsletter-Rubric exhibited good overall reliability. We suggest that the use of a rubric to assess pre-kindergarten teacher-created monthly DVD classroom newsletters supports teachers’ decision making about technology uses and professional development.     

Project- versus lecture-based courses: Assessing the role of course structure on perceived utility,anxiety, academic performance,and satisfaction in the undergraduate research methods course

Previous research suggests that undergraduate research methods students doubt the utility of course content and experience math and research anxiety. Research also suggests involving students in hands-on, applied research activities, although empirical data on the scope and nature of these activities are lacking. This study compared academic performance, research methods anxiety, perceived utility of research methods, and course satisfaction across students in a large lecture-based course and a smaller project-based course. Results show minimal differences in student outcomes between the courses. Limitations are discussed, as is the ideal scope of project-based learning in the undergraduate mass media research methods course.     

Using a Standardized Task to Assess the Quality of Teacher–Child Dyadic Interactions in Preschool

Research Findings: This study explored the quality of teacher-child interactions within the context of a newly developed standardized task, Teacher-Child Structured Play Task (TC-SPT). A sample of 146 teachers and 345 children participated. Children who displayed the highest disruptive behaviors within each classroom were selected to participate. Teacher-child dyads (n=345) participated in a play session that included free play and clean-up tasks. We adapted two coding schemes to assess the quality of both teachers’ and children’s interactive behaviors during these two tasks. The coding schemes exhibited internal and inter-rater reliability. Significant associations with classroom-level teacher-child interactions and children’s observed classroom engagement provide support for the measure’s validity. Differences in teacher and child-interactive behaviors across the two tasks (free play versus clean-up) suggest that task features may affect the quality of teacher-child interactive behaviors. Practice and Policy: Examining the interactions of different teacher-child dyads within the same standardized context will allow researchers to better understand the child and teacher factors that contribute to the quality of those interactions. Thus, use of this task in future field-based research may help to assess the impact of early interventions and professional development efforts that target improvement in the quality of teacher-child interactions.     

Framing secondary teachers’ perspectives on the inclusion of students with autism spectrum disorder using critical discourse analysis

Research on the role of teachers in supporting students with autism spectrum disorder (ASD) in schools in the Republic of Ireland has largely focused on primary and special schools rather than secondary school settings. This study examined the theoretical and practical knowledge base of Irish secondary teachers regarding the inclusion of learners with ASD using an ecological critical discursive perspective. Findings revealed teachers’ strong desires to include students with ASD in their classrooms. Teachers’ discourses exposed their sense of low self-efficacy in relation to pedagogical skills required to meet the needs of learners with ASD. At a school level, teachers positioned themselves outside the dominant school discourse on special education needs. Using critical discourse analysis (CDA), teachers’ narratives re-focus the spotlight on issues such as ineffective legislation and inadequate policies at national level, and identified the impact that these have at a micro-analytical level on teachers’ practices in relation to inclusion.     

Make or break: the role and support needs of academic advisors in work-integrated learning courses

ABSTRACT

The role of academic advisors in work-integrated learning courses is crucial to student success, yet poorly understood. This research aimed to understand the role and support needs of academic advisors by conducting interviews, a survey, and a focus group within a service learning program in Queensland, Australia. Participants identified rewards in observing student transformation and supporting students to contribute to social justice causes. However, the role had high demands in terms of pastoral support. Although academic advisors reported strong support mechanisms, they identified gaps in supporting them to meet the needs of international students and students with mental health issues. Academic advisors need strong mentoring or supervisory support to deal with diverse student issues, clear processes for tracking and managing students, training and resources to deal with special needs students, and opportunities for team building and bonding. Supporting academic advisors could help to better support students to successfully complete internships.     

Concept-Mapping as a Research Tool: A Study of Primary Children's Representations of Information and Communication Technologies (ICT)

This paper presents an approach to concept-mapping that was used in an EU-funded project to study ten year old pupils' representations of Information and Communication Technologies (ICT). The research task – to draw a concept map of computers in today's world – was administered to children in six EU countries twice. In England this took place immediately before and after the introduction of networked PCs in their schools. They were asked to use their maps to communicate their ideas through drawing to the researchers and other children who did not all speak the same language as them. The maps were analysed both quantitatively and qualitatively, using phenomenographic methods combined with semiotic interpretation. The maps showed that the children had well-developed mental representations (secondary artifacts) of the role of ICT in today's world, even when they had little or no practical experience of using the Internet. Psychological theories suggest that learning depends to a considerable extent on the development of secondary artifacts of this kind. The extent and variety of knowledge about computers demonstrated by all children in the cohort came as a surprise and suggested that they would be very well prepared to develop sophisticated ICT skills once they had good access to ICT tools. Current approaches to ICT use in primary schools, involving explicit, systematic teaching of ICT skills, may therefore not be making the most cost-effective use of scarce resources. Exploratory use of ICT within open-ended project work, reflecting the kind of use that computer-literate adults make of ICT, might be more likely to provide the context for children's rapid development of a complex range of ICT skills.     

Using Graph Talks to Engage Undergraduates in Conversations Around Social Justice

Abstract

We present a mathematical activity called graph talks as a new pedagogical routine to intertwine social justice issues and mathematics. Adapted from number talks, graph talks involve students analyzing, interpreting, and discussing real-life data represented in graphs. Graphs may be strategically selected to both highlight a relevant social justice issue while also reinforcing the mathematics content of the course. We report on experiences using graph talks in undergraduate mathematics content courses for future teachers in the USA, and provide examples of the undergraduates doing mathematics while analyzing the social justice context of the graphs.
