The Musical Ear Test,a new reliable test for measuring musical competence

This paper reports results from three experiments using the Musical Ear Test (MET), a new test designed for measuring musical abilities in both musicians and non-musicians in an objective way with a relatively short duration (< 20 min.). In the first experiment we show how the MET is capable of clearly distinguishing between a group of professional musicians and a group of non-musicians. In the second experiment we demonstrate that results from the MET are strongly correlated with measures of musical expertise obtained using an imitation test. In the third experiment we show that the MET also clearly distinguishes groups of non-musicians, amateurs and professional musicians. The test is found to have a large internal consistency (Cronbach alpha: 0.87). We further show a correlation with amount of practice within the group of professionals as well as a correlation with a forward digit span test.     

FROM WAC TO MEW TO MET: THE EVOLUTION OF A MORE EFFECTIVE TEACHING PROGRAM

In three years, Stetson University's More Effective Teaching Program (MET) has evolved from a writing‐across‐the‐curriculum faculty development program into a voluntary collaborative learning and teaching project. Based originally on the pedagogy associated with “writing‐to‐learn,” it contains five components that have been designed and adapted to enhance the university as a community of learning and teaching. However, what MET is does not seem as important as the way it has evolved and remained vital. A faculty committee established and maintained MET by using positive wording, tone, and attitudes; by utilizing existing research and assessment efforts to institute each successive program; and by insisting that all elements be conducted as grassroots faculty efforts. As well establishing a diversity of effective faculty development programs, Stetson University has benefited from MET because it has created expectations for the evolution and the improvement of on‐going programs.

Understanding attrition in UK maritime education and training

The shipping industry worldwide is experiencing a shortage of trained and qualified officers to operate a rapidly expanding global merchant fleet. High cadet wastage in Maritime Education and Training (MET) institutions is an obstacle to skills replenishment in the UK. This paper examines the specificity of MET programmes with regard to the question of attrition and explores the intricate ways in which globalisation in the industry and the seafaring sector has influenced declining training opportunities and rising attrition rates in the UK.

Noticing and weighing alternatives in the reflection of regular classroom teaching: Evidence of expertise using mobile eye-tracking

Instructional videos are widely used to study teachers’ professional vision. A new technological development in video research is mobile eye-tracking (MET). It has the potential to provide fine-grained insights into teachers’ professional vision in action, but has yet been scarcely employed. We addressed this research gap by using MET video feedback to examine how expert and novice teachers differed in their noticing and weighing of alternative teaching strategies. Expert and novice teachers’ lessons were recorded with MET devices. Then, they commented on what they observe while watching their own teaching videos. Using a mixed methods approach, we found that expert and novice teachers did not differ in the number of classroom events they noticed and alternative teaching strategies they mentioned. However, novice teachers were more critical of their own teaching than expert teachers, particularly when they considered alternative teaching strategies. Practical implications for the field of teacher education are discussed.
