Developing a science teacher education course that supports student teachers’ thinking and teaching about the nature of science

This paper reports on part of an ongoing research project in England concerning the Nature of Science (NOS). The particular focus is on the initial thinking of the graduate scientists starting a one-year, Postgraduate Certificate of Education (PGCE) course and the way the course approaches adopted influence their views and understanding of NOS and their teaching. The research is set against a wealth of literature indicating that teachers find it difficult to teach curricula that emphasise NOS. Thus a key impetus for research in this area has been to look for ways that beginning teachers might be better prepared to face such challenges.

Sample

The paper draws on data from three cohorts of secondary PGCE students in a university–schools partnership, involving a total of 169 students.

Design and method

The research lies within a design research tradition. It has used mixed methods, involving written tasks, interviews and focus groups, with an iterative approach where the outcomes from one cohort have been used to inform course developments in successive years.

Results

The results from these cohorts suggest that, while the students starting the course have a less restricted view of NOS than indicated by some other studies, in most cases there is a lack of breadth and depth to their understanding. There is some evidence that the use of specific tasks focusing on NOS in university-based sessions may be helping to develop and deepen understanding. However, the impact of current approaches remains fairly limited and attempts to develop teaching practices often face considerable barriers in the school-based practicum.

Conclusions

Graduate science students’ understanding of NOS as they embark on the PGCE is not highly developed. Hence, the emphasis on aspects of NOS in the school curriculum presents a considerable challenge. This study suggests that there is a need to both further develop an explicit focus on NOS in university-based sessions and to develop closer relationships between schools and university faculty in seeking to support developments in classroom practice in this difficult area.     

Examination standards and the limits of linking

There is a tendency in the literature to characterize linking as equating done somewhat less rigorously. The ambiguity of this conception can lead to confusion amongst policy‐makers and members of the public and can result in the proliferation of comparability myths. As the constructs assessed by two tests decrease in similarity, so the difference between equating and linking becomes one of kind rather than degree. To help make sense of linking in different contexts, a general model is proposed, based upon the idea of a ‘linking construct’. This general model is used to define the limits of linking and to clarify what users and stakeholders need to know about linking and linked scores. Finally, a distinction is drawn between judgemental linking as a method (e.g., social moderation) and judgemental linking as a theory (i.e., the value judgement theory of linking). The latter presents a challenge to the general model, which is defended.     

What Teachers See as Creative Incidents in Elementary Science Lessons

Teachers are often urged to nurture creativity but their conceptions of creativity in specific school subjects may have limitations which weaken their attempts to do so. Primary school teachers in England were asked to rate lesson activities according to the opportunity they offered children for creative thought in science. The teachers could, overall, distinguish between creative and reproductive activities but, as predicted, there was evidence of narrow conceptions of school science creativity, biased towards fact finding, practical activity, and technological design. Some teachers saw creativity in essentially reproductive activities and in what simply stimulated interest and on‐task talk. Some implications and recommendations for teacher training and professional development are discussed.     

The Effects of Instruction on Students' Generation of Self-Questions When Reading Multiple Documents

The purpose of this research was to examine the effects of instruction on students' generation of questions when reading multiple documents. Participants were 151 undergraduate students who were randomly assigned to one of two conditions: a treatment condition that received question generation instruction and a control condition that did not receive question generation instruction. All participants read four primary-source documents and were asked to generate up to 10 questions based on those documents. Results indicate that students generated significantly fewer higher-order integration questions without instructional support. These results are replicated with an alternative document set to demonstrate that the effects found were not due to the specific historical topic.     

Evolution of Teachers’ Technology Integration Knowledge,Beliefs, and Practices: How Can We Support Beginning Teachers Use of Technology?

Abstract

In this study, we examined a group of four teachers who completed extra educational technology coursework and field experiences during their teacher education programs to determine how their technology integration knowledge, self-efficacy beliefs, intentions, and practices evolved over time. We conducted interviews and evaluated data sources at three intervals: (1) after teacher education coursework was completed, (2) after student teaching was completed, and (3) after two initial years of teaching. Results showed that school resources and environment had a strong impact on beginning teachers' practices, regardless of strong internal enabling factors.     

Standards and assessment: coherence from the teacher’s perspective

We sought to understand how teachers’ perspectives on standards-based instructional practices, classroom assessment, and external testing do or do not show coherence and alignment. Based on survey methods (n?=?155) and interviews with a sample of secondary school teachers (n?=?9) in a large urban district in the USA, we explored general trends and individual teachers’ viewpoints. Our results suggest that the teachers’ instructional use of standards, classroom assessment preferences, and beliefs about the test-driven system are moderately correlated. Interview data provide insight into reasons teachers hold beliefs that do or do not fit well into a coherent assessment system.     

Articulation and student intentionality in professional development: A proactive model for teacher educators

Abstract

The Early Childhood Education and Care (ECEC) professional development movement, community college students’ emerging intentionality, and the role of two‐ and four‐year higher education faculty intersect in a proactive model proposed by the author that advocates ECEC community college programs separate from the vocational tradition and establishes ECEC transfer degrees to four‐year programs. Degree structures must be built with flexibility, and encompass checkpoints and highly articulated options as student intentionality unfolds. The proactive model is constructed from Morgan's (1994) 21 st century model of professionalism and her conception of students’ emerging intentionality, combined with Brint and Karabel's (1989) models that attempt to explain why community colleges moved from conferring primarily transfer degrees to conferring primarily vocational degrees.     

Manipulatives Work!

This essay invites reflection on the phenomena of time as it impacts the day-to-day life of teachers. It also explores assumptions about time and teaching in three areas: first, beliefs about the force of time and the teacher's struggle to control it; second, beliefs about the potential of time and the benefits of its passing for teachers and students; and finally, beliefs about significant moments in time and the teacher's courage to be appropriately responsive to them.     

Factors associated with caregiver stability in permanent placements: a classification tree approach

Objective

Identify individual and environmental variables associated with caregiver stability and instability for children in diverse permanent placement types (i.e., reunification, adoption, and long-term foster care/guardianship with relatives or non-relatives), following 5 or more months in out-of-home care prior to age 4 due to substantiated maltreatment.

Methods

Participants were 285 children from the Southwestern site of Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Caregiver instability was defined as a change in primary caregiver between ages 6 and 8 years. Classification and regression tree (CART) analysis was used to identify the strongest predictors of instability from multiple variables assessed at age 6 with caregiver and child reports within the domains of neighborhood/community characteristics, caregiving environment, caregiver characteristics, and child characteristics.

Results

One out of 7, or 14% of the 285 children experienced caregiver instability in their permanent placement between ages 6 and 8. The strongest predictor of stability was whether the child had been placed in adoptive care. However, for children who were not adopted, a number of contextual factors (e.g., father involvement, expressiveness within the family) and child characteristics (e.g., intellectual functioning, externalizing problem behaviors) predicted stability and instability of permanent placements.

Conclusions

Current findings suggest that a number of factors should be considered, in addition to placement type, if we are to understand what predicts caregiver stability and find stable permanent placements for children who have entered foster care. These factors include involvement of a father figure, family functioning, and child functioning.

Practice implications

Adoption was supported as a desired permanent placement in terms of stability, but results suggest that other placement types can also lead to stability. In fact, with attention to providing biological parents, relative, and non-relative caregivers with support and resources (e.g., emotional, financial, and optimizing father involvement or providing a stable adult figure) the likelihood that a child will have a stable caregiver may be increased.
