Aquaculture — towards the future

Although the visionary aquatic worlds of the 1960s, in which vast sea-herds were to be reared for the good of mankind, are yet to be realised, aquaculture — the managed production of aquatic organisms — has been making steady and sometimes dramatic progress in recent years. That it has done so in spite of often shrinking resources is a tribute not only to the scientific advances and new technologies being evolved, but to the increasing skill in applying these in the right context. Present annual world aquaculture production of fin fish is estimated at 5 million tonnes, plus crutacea and edible algae.     

Up,close and personal: teachers' responses to an individualised professional learning opportunity

This paper provides an account of professional learning in action through documenting the experiences of three upper primary teachers as they engaged in reflection-on-action with the assistance of an academic mentor. Video-stimulated recall was used as a mechanism to encourage productive reflective practice, using video footage of each teacher's numeracy lessons. The results indicated that although it was a powerful medium for stimulating reflection, and the teachers indicated that it was a beneficial process, there was limited evidence to suggest that it resulted in substantial changes to their practices. Reasons for this are hypothesised and recommendations made for personalising professional learning to cater for the needs and context of individual teachers.     

Developing the Coach Analysis and Intervention System (CAIS): establishing validity and reliability of a computerised systematic observation instrument

We outline the evolution of a computerised systematic observation tool and describe the process for establishing the validity and reliability of this new instrument. The Coach Analysis and Interventions System (CAIS) has 23 primary behaviours related to physical behaviour, feedback/reinforcement, instruction, verbal/non-verbal, questioning and management. The instrument also analyses secondary coach behaviour related to performance states, recipient, timing, content and questioning/silence. The CAIS is a multi-dimensional and multi-level mechanism able to provide detailed and contextualised data about specific coaching behaviours occurring in complex and nuanced coaching interventions and environments that can be applied to both practice sessions and competition.     

Four components of Rotter's internal-external scale and cheating behavior

This paper studied correlations between classroom cheating and the four subscales of Rotter's I-E scale identified by Collins. One-hundred-thirty college undergraduates completed the Rotter scale converted to 46 Likert items and a 30-item multiple-choice, introductory psychology examination under crowded classroom conditions. Cheating, as indexed by answer overlap with adjacent neighbors as compared to answer overlap with distant subjects, correlated significantly with the difficult-easy subscale but not with the other subscales, and not with the overall I-E scale. Results are taken as justification for the Collins' subscales and are discussed in terms of the multidimensional aspects of the overall I-E dimension.
