Competing priorities in professional development: an Australian study of teacher professional development policy and practice

This paper argues that neoliberal and managerial pressures external to the teaching profession, as well as more progressive and democratic approaches internal to the profession, have simultaneously influenced professional development policy and practice in Australia. In making this case, the paper reviews the nature of the teacher professional development that is supported in federal Australian policies associated with the recently defeated Liberal/National Coalition government (1996–2007) and research into how professional development has been enacted in practice in Australia, during this government's tenure. While acknowledging the significant impact of more neoliberal and managerial approaches and how such policy emphases contribute to the continuation of traditional, systemic/employer provided workshops, the paper also provides evidence of competing, more teacher‐centred approaches.

Community-based inquiry improves critical thinking in general education biology

National stakeholders are becoming increasingly concerned about the inability of college graduates to think critically. Research shows that, while both faculty and students deem critical thinking essential, only a small fraction of graduates can demonstrate the thinking skills necessary for academic and professional success. Many faculty are considering nontraditional teaching methods that incorporate undergraduate research because they more closely align with the process of doing investigative science. This study compared a research-focused teaching method called community-based inquiry (CBI) with traditional lecture/laboratory in general education biology to discover which method would elicit greater gains in critical thinking. Results showed significant critical-thinking gains in the CBI group but decreases in a traditional group and a mixed CBI/traditional group. Prior critical-thinking skill, instructor, and ethnicity also significantly influenced critical-thinking gains, with nearly all ethnicities in the CBI group outperforming peers in both the mixed and traditional groups. Females, who showed decreased critical thinking in traditional courses relative to males, outperformed their male counterparts in CBI courses. Through the results of this study, it is hoped that faculty who value both research and critical thinking will consider using the CBI method.     

Measuring the quality of e‐learning

This paper shows how concept mapping can be used to measure the quality of e‐learning. Six volunteers (all of them 3rd‐year medical students) took part in a programme of e‐learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping. The quality of change in individuals' maps was assessed using criteria developed to distinguish between meaningful and rote‐learning outcomes. Student maps were also scored for evidence of conceptual richness and understanding. Finally, each map was compared directly with the content of the electronic teaching material. The results show that many of the student misconceptions were put right in the course of their learning but that many of the key concepts introduced in the teaching were ignored (or sometimes learnt by rote) by the students. This was because the teaching material locked these new ideas in structures and terminology that precluded meaning‐making among non‐experts. Our data suggest that students' prior knowledge is a key determinant of meaningful learning. We suggest that this must be acknowledged if the design and use of electronic teaching material is also to be meaningful. Ultimately, measures of student learning are the only authentic indicators of the quality of teaching through technology.     

Self-regulated strategy development in writing: Going beyond NLEs to a more balanced approach

In this article, we present an argument for consideration by those researching and promoting new learning environments (NLEs). We believe advocates of NLEs should consider the literature and research base indicating effective instruction is not based on a forced dichotomy between theoretical perspectives, but rather a thoughtful, pragmatic blending of practices based on evidence gained from various perspectives and lines of research. While unguided or minimally guided instructional approaches are popular and intuitively appealing, these approaches ignore substantial evidence indicating these approaches are less effective and less efficient than instructional approaches that incorporate guidance of the learning process that is faded as internal guidance is developed (Kirschner et al., Educ Psychol 41:75–86, 2006). We illustrate how integrating evidence from multiple theoretical perspectives leads to the development of more powerful approaches to learning and instruction through a review of the premises, evolution, and research behind Self-Regulated Strategy Development (SRSD) in the area of writing.
