Do we expect too much? Reflection on chemistry content in higher education

Education research in the 1970s, like other related areas, was dominated by quantitative work¹ during an era for which social sciences sought to draw upon the successful scientific approach typically used in the physical sciences (in particular) to investigate teaching and learning.¹’² So if we felt a cohort of students did not understand some con¬cept, we tried to find out whether or not a different teach¬ing approach could fix their misconceptions.³ But how to do this? Well, drawing on a scientific approach, we would divide the class or classes up, teach one cohort the same way we always had, and the other cohort in our new way, and evaluate any differences in conceptual understanding using, e.g. a standardized topic test. Differences would be examined for statistical significance of evidence that our new approach to teaching had worked. And this is the way much research was done at the time. Control of variables, randomized sampling, and so on, were all embedded in such an approach to educational research

The influence of context on science curricula: Observations, conclusions and some recommendations for curriculum development and implementation

The genesis of this project and book was our experiences of teaching science and science education at various levels in developing countries; in the Pacific and the Caribbean. These experiences along with numerous conversations with other teachers and educators who had worked in Africa and elsewhere left us with something of a sense of despair. We constantly confronted Western or foreign science curricula which were plainly alien to science learners in non-Western contexts. We witnessed numerous curricula reforms and professional development initiatives, many of which seemed doomed to failure. In fact Helu-Thaman (1991) referred to the ‘wreckage’ of aid-funded curricula initiatives all around the Pacific. Probably the most alarming aspect in all of this was the role of the foreign expert. Someone, normally ‘aid-funded’, who turned up for a short period of time to tell the locals what they should be doing! The naiveté of some of these people was truly remarkable (or perhaps they just didn’t care?). Failure of the program or reforms was generally attributed to the locals not ‘seeing it through’ or not quite understanding the new curriculum initiatives. There was little effort made to take into account local conditions or the views of local experts, especially teachers

Science education in context: An overview and some observations

This book presents an international perspective of the influence of educational context on science education. By this we mean the context in which the teaching and learning takes place, rather than the use of a context-based approach to learning and teaching (Pilot & Bulte, 2006). The focus is on the interactions between curriculum development and implementation in non-Western and non- English-speaking contexts (i.e., outside the UK, USA, Australia, NZ, etc.)

Learning science and technology through cooperative education.

Cooperative education, a form of experiential or work‐integrated learning is common in tertiary educational institutions worldwide. However, in New Zealand few institutions provide work‐integrated learning programs in science or technology, and the management and process of work‐integrated learning programs is not that well understood. How well do such programs work? What infrastructure is needed to ensure learning actually occurs? Are graduates of work‐integrated learning programs able to satisfy employer needs? This chapter synthesizes decades of work around such issues, and details research initiatives that provide valuable insights into how students learn science on in the workplace, how their skill development matches that desired by employers, and best practice for management of work‐integrated learning in science and engineering (Asia‐Pacific Journal of Cooperative Education, 2007, 8(2), 131‐147)

A critical analysis of interpretive research studies in cooperative education and internships

Much research in co-op has utilized a quantitative or experimental approach within a positivist paradigm. Here we present a critical analysis of interpretive/qualitative studies in terms of output, diversity, quality, along with an overview of the topics investigated. Our analysis suggests that interpretive work is a substantial part of co-op research output, and that is spans a wide range of programs, disciplines and geographical locations. Similar themes to those investigated by a quantitative approach are investigated by interpretive researchers, but there is emphasis in interpretive work on understanding more details of co-op issues in relation to the educational context

Authentic student inquiry: the mismatch between the intended curriculum and the student-experienced curriculum

As a means of achieving scientific literacy goals in society, the last two decades have witnessed international science curriculum redevelopment that increasingly advocates a 'new look' inquiry-based approach to learning. This paper reports on the nature of the student-experienced curriculum where secondary school students are learning under a national curriculum that is intent on promoting students' knowledge and capabilities in authentic scientific inquiry, that is, inquiry that properly reflects that practiced by members of scientific communities. Using a multiple case study approach, this study found that layers of curriculum interpretation from several 'sites of influence' both outside and inside of the schools have a strong bearing on the curriculum enacted by teachers and actually experienced by the students, and runs counter to the aims of the national curriculum policy. Over-emphasis on fair testing limits students' exposure to the full range of methods that scientists use in practice, and standards-based assessment using planning templates, exemplar assessment schedules and restricted opportunities for full investigations in different contexts tends to reduce student learning about experimental design to an exercise in 'following the rules'. These classroom realities have implications for students' understanding of the nature of authentic scientific inquiry and support claims that school science is still far removed from real science

Investigating the effectiveness of teaching methods based on a four-step constructivist strategy

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade 9 classes in the city of Trabzon, Turkey. Data collection employed a purpose-designed ‘solution chemistry concept test’, consisting of 17 items, with the quantitative data from the survey supported by qualitative interview data. The findings suggest that using different methods embedded within the four-step constructivist-based teaching strategy enables students to refute some alternative conceptions, but does not completely eliminate student alternative conceptions for solution chemistry

Investigating scientific literacy: Scientist’s habits of mind as evidenced by their rationale of science and religious beliefs

Science and technology have been incredibly success¬ful in purely technical terms. For instance, international air travel, space flight, and curing of hitherto untreatable medical illnesses all are now routine events. One feature of the incredible (and seemingly ever increasing) advance of science and technology is a sense of unease amongst the general population of science’s potential to change our lives, in sometimes unpredictable and alarming ways. Public understanding of science, or scientific literacy, is of increasing concern worldwide according to much recent literature

Developing a survey instrument to evaluate tertiary chemistry students' attitudes and learning experiences

New Zealand tertiary institutions, like others worldwide, have experienced a decline in science and chemistry enrolments in recent times as students seek other career paths that they perceive to be more lucrative. In a previous article we described a qualitative study of the learning experiences of students enrolled in a first year chemistry course at a New Zealand tertiary institution. Researchers in education and science education have two choices of methodology, a qualitative or a quantitative approach, and each possesses advantages and disadvantages. Qualitative studies typically use resource intensive data gathering techniques such as interviews. These studies are useful in that they allow researchers to study issues of interest in great depth and, for example, allow investigators to probe for underlying reasons about students' views for abstract scientific concepts. However, because qualitative studies are more labour intensive, they typically involve only small numbers of participants, which in the minds of many researchers and teachers results in a lack of generalisability. In other words, it is not necessarily clear what implications the findings hold in other contexts. In contrast, quantitative studies involve larger numbers of participants. By the judicious use of statistical analysis, researchers can investigate changes and trends, and extrapolate their findings to a large (or target) population. However, whilst the results from quantitative studies are more generalisable, they are often less detailed. Hence researchers are confronted with a trade-off situation in which they must choose between the depth of understanding provided from qualitative studies, versus the generalisability of a quantitative approach: because of this dilemma, increasingly researchers employ a mixed methodology approach. In this paper we describe a quantitative study that complements previous qualitative work. We report on the development of a questionnaire that investigates tertiary level learning experiences of chemistry students, along with their attitude toward chemistry and chemistry self-efficacy
