“Effective Teaching of Mathematics” by Teachers, for Teachers: An Australian Case Study

Researchers and theorists differ whether teachers’ reflection on their classroom practices and teaching mathematics effectively are linked or not. This study aims to align the benefits of reflective practice with the quality of education and the learning of mathematics. A qualitative case study was conducted with five mathematics teachers at a high school in a rural area of the Free State. Data were collected by conducting interviews and observing lesson presentations. The reflective aspect was evaluated by employing Lee’s (2005) three levels of reflection – ‘recall level’, ‘rationalisation level’ and ‘reflective level’. The quality of the teachers’ mathematics instruction was compared to the principles for effective teaching set by Anthony and Walshaw (2009). The study found that there was indeed a link between the teachers’ reflective classroom practice and their effectiveness in facilitating the learning of mathematics. The teachers who were more reflective in the preparation and presentation of their lessons, were also evaluated to be more effective teachers than those who were less reflective. The results of the study have implications for the professional development of practising teachers – not only due to the fact that teachers should be trained and encouraged to reflect on their teaching and the learning of mathematics, but also because they have to discuss the effective teaching of mathematics cooperatively with their fellow teachers.

Research attributes low fruit and vegetable consumption to problems of access, availability and affordability. We conducted, for the first time, a case study with three families designed and analysed using the sustainable Livelihoods Framework. The benefit of such an approach is that we moved away from identified barriers and towards identifying the capabilities and resources low-income families use to incorporate fruit and vegetables into their diets. Mitigating cost and access, we provided families with a box of fresh fruit and vegetables free of charge for up to 10 weeks and observed and recorded how/if the contents were used. Results identify the importance of social networking, organizational skills, knowledge of health benefits, and social structures. This paper demonstrates an effective methodology for understanding the capabilities of, rather than barriers to, low-income families increasing fruit and vegetable intake. Additionally, we provide a ‘how to’ and ‘lessons from the field’ for researchers interested in conducting research of this nature.

The forest industry tends to plan, and model transportation costs based on the potential payload benefits of increased legal gross vehicle weight (GVW) by deploying different configurations, while payload benefits of a configuration can be significantly influenced by the vehicle design tare weight. Through this research the relative benefit of increased legal GVW of different configurations is compared across Australia over a 13-year period from 2006 to 2019, by examining data collected post operation across multiple operations. This approach is intended to offer realistic insight to real operations not influenced by observation and thus reflect long-term operating behaviour. The inclusion of the three most common configuration classes in Australian forestry over a 13-year period has also allowed the exploration of load management between configurations and potential trends over time. When considering the legal GVW and the tare weight impacts across the fleets, the semi-trailer has an 8 t payload disadvantage compared to B-Doubles and 19.6 t disadvantage compared to road trains.
