Implementing a context-based environmental science unit in the middle years: Teaching and learning at the creek

Engaging middle-school students in science continues to be a challenge in Australian schools. One initiative that has been tried in the senior years but is a more recent development in the middle years is the context-based approach. In this ethnographic study, we researched the teaching and learning transactions that occurred in one 9th grade science class studying a context-based Environmental Science unit that included visits to the local creek for 11 weeks. Data were derived from field notes, audio and video recorded conversations, interviews, student journals and classroom documents with a particular focus on two selected groups of students. This paper presents two assertions that highlight pedagogical approaches that contributed to learning. Firstly, spontaneous teaching episodes created opportunities for in-the-moment questioning by the teacher that led to students’ awareness of environmental issues and the scientific method; secondly, group work using flip cameras afforded opportunities for students to connect the science concepts with the context. Furthermore, students reported positively about the unit and expressed their appreciation for the opportunity to visit the creek frequently. This findings from this study should encourage teachers to take students into the real-world field for valuable teaching and learning experiences that are not available in the formal classroom.

Environmental science and sustainability: some critical thoughts

Environmental science is often described as an interdisciplinary subject, but one firmly grounded in positivist science. Less well recognized is the idea that interdisciplinarity actually challenges fundamental conceptions concerning how reality is understood from an orthodox science perspective. Drawing on recent non-dualism (or post-natural) literature, it is suggested in this paper that there is a need for greater awareness and debate concerning the underlying challenges that ideas of interdisciplinarity and holism present for environmental science. It is argued by aligning environmental science more strongly with non-dualistic traditions (spanning the sciences, arts and religion), fundamental issues are raised concerning how reality is understood and what constitutes valid research methodologies. The concept of intrinsic value is used as one example of the way non-dualistic theory can open up new territories for exploring reality.

EU Environmental Policy under Pressure: Chemicals Policy Change between Antagonistic Goals?

Until now, chemicals policy was unable to find a method to establish a sound balance between the benefits and risks of chemical substances. Policy learning within the European Union (EU) resulted in the formulation of an alternative approach to future chemicals policy in some quarters. The Commission's proposal for new chemicals legislation - presented as 'paradigmatic' policy change - led to a highly controversial lobbying debate. This paper deals in particular with the influence of structures, policy networks, multi-level governance and the influence of new modes of governance on chemicals policy-making. It argues that future policy will not represent the paradigmatic change announced by the Commission but only one incremental, cost-effective step towards such a reform. The final proposal is criticised as a neo-liberal interpretation of the Lisbon strategy which includes a dangerous shift in environmental policy making.

Understanding student expectations in developing environmental science courses

Developing relevant and innovative University courses is a complex and often difficult task. This is particularly true when developing environmental science courses as the banner of environmental science has the potential to include an extremely vast array of subject material and course content. Added to this is the diversity of students entering these courses, and their associated course expectations and aspirations. A third component that cannot be ignored when developing courses includes employer demands and expectations of graduates at course completion. As tertiary educators we therefore have the challenge of developing innovative environmental science courses that are academically challenging, but meet the expectations of students, staff and potential future employers. To ensure that we meet this challenge it is vital that we determine the expectations of all relevant parties (students, staff, and potential employers) and develop our courses accordingly.  Here we report on the 'student expectations' component of this. To determine student expectations we conducted a survey of all commencing first year environmental science students. The survey asked students to provide information on drivers for course selection, preferred learning styles, the importance of different approaches to teaching, subject interest areas and employment aspirations. Our results found that environmental science students have a preference for fieldwork and hands-on experience and are very supportive of teaching that combines different teaching methods. On-line teaching was not supported by commencing environmental science students. Commencing students showed a very strong interest in key subject areas of environmental science such as Wildlife, animal conservation, national and marine parks, conservation and marine Wildlife; however, some of the critical areas of environmental science such as population statistics, social sciences and chemistry did not attract the same level of interest. Most commencing students had some idea on where they would like to gain employment on course completion. Knowledge relating to student expectations is Vital, particularly when designing courses, developing specific unit content and undertaking marketing and course information sessions. With this knowledge we can be confident that students enrolling in environmental science will, to a large extent, have their expectations met.

Wholly online learning in environmental science

In recent years there has been a significant shift in the way courses and subjects are delivered to students in tertiary institutions. Advances in technology have resulted in a change to the traditional face-to-face lecture and tutorial teaching format, with many subjects in tertiary education now available online. Although research has explored the advantages and disadvantages of online learning, there has been little attention paid to this teaching format in the field of environmental science. In particular, there is little evidence in the literature to suggest that this method of teaching is appropriate for studies in environmental science or for environmental science students. This study examined the outcomes from a wholly online subject in environmental science at Deakin University, Australia. More specifically, the study aimed to investigate student views about online learning in environmental science as well as online group work. Questionnaires were distributed to all students who completed the core second year subject Society and Environment in semester 1, 2005. Although many of the responding students (n = 48) recognised the benefits of wholly online learning, the findings suggest that most prefer to learn in a face-to-face environment. This paper examines the implications of these findings for future online teaching methods in this discipline.
