Musical improvisation is a sophisticated activity in which a performer realizes, real-time, melodic, and rhythmic sequences in harmony with those from other musicians. The study of musical improvisation helps one to understand not only the cognition of creativity, but also the complex neuronal basis of executive functions, the relation between conscious and unconscious action, and even more. So far, the prevailing models, founded on the brain imaging method, have focused on the connection between the cortical areas and their cognitive processes. (...) Little attention, on the other hand, has been given to the huge variety of subcortical activities, especially in the basal ganglia. This fundamental subcortical component, through its implicit procedures and the role it plays in memory, is responsible to produce new information all the time, allowing the prefrontal cortex to transform a huge and disordered amount of data in explicit creative acts. The basal ganglia are strongly related to the activation of chemical signals generated by dissonance or lack of symmetry between perception and expectation, participating even in the responses to environmental demands according to the circumstances. Thus, they interact with the frontal cortex and with the limbic system, playing a key role in planning and selecting appropriate actions and in decision making. In this text, we try to explain in which sense improvisation is connected to the processes of executive functions, to creativity and to the integrated activity of cortical–subcortical areas controlling the free flow of ideas and to expressive spontaneity. Eventually, we purpose a model according to which structure and process take part at the centrencephalic space of functional integration, which, through both competing and cooperating dynamics, gives way to spontaneous composition.

This article draws on the ecological model of teacher agency and elaborates on how teacher agency is achieved, its components and how it could be strengthened. This model highlights professional competence, structural and cultural context, and professional purpose as the main elements of achieving agency. In this paper, we specify some elements of the ecological model and elaborate on how three types of reflection could be used to strengthen conditions for achieving teacher agency. These include, first, procedures aimed at articulating (...) the theory of action, including effective strategies, rules and principles for practice; second, procedures of practical reflection, aimed at fostering the conceptualization of practice and the understanding of oneself as a teacher; and third, procedures of critical reflection, which help to address the inequalities and malpractices of education and society. The main importance of this paper is to extend the practical relevance of the ecological model for teacher learning settings. (shrink)

This study investigated contributions of pre-service teachers’ endogenous and exogenous instrumentalities, their intrinsic and extrinsic motivations, and their use of self-regulation strategies to explain the extent to which they used strategies to purposefully integrate their knowledge across courses. With a total of 254 pre-service teachers’ survey-responses, results of a hierarchical multiple regression analysis indicated that their endogenous instrumentality of their current coursework, their use of metacognitive strategies and their use of deeper cognitive learning strategies contributed to explaining their use of (...) extensive knowledge integration strategies for completing coursework. Our results suggest that to develop pre-service teachers’ teaching expertise, they may need to have a strong understanding that the current course conte... (shrink)

Knowledge of pedagogy and social studies content influences a teacher's decision making and helps teachers conduct sound instructional practices despite the influence of high-stakes testing policies. Using national data from the Survey of the Status of Social Studies (S4), this study examined the associations of teachers’ professional characteristics, school environmental factors, and state testing policy on self-reported levels of authority that secondary level social studies teachers (grades 6–12) hold over key classroom tasks. Through hierarchical multiple regression analysis, key findings from (...) this study indicated that greater minority enrollments are associated with lower levels of instructional authority. Teachers who worked in states where a state-mandated social studies test was administered reported less freedom to choose what to teach and how to teach than those in non-testing states. Also, this study showed that in-field status, the type of licensure, and years of teaching experience are important factors in exercising social studies teachers’ instructional authority (e.g., their ability to balance effectively the demands of state-mandated reforms with teaching for meaningful student learning). This study recommends that schools with high minority enrollments, especially if these districts exist in a high stakes testing environment, should invest in teachers with high-quality social studies preparation.

The framework, Technological Pedagogical Content Knowledge, Ethics and Accomplishment (TPACKEA) provides an extension to a modified TPACK framework by adding ‘Ethics’ and ‘Accomplishment’. The reason is that further theoretical formulations and deployments need to be carried out on Technological Pedagogical Content Knowledge (TPACK) if TPACK research is to harmonize and constructively strengthen the field of blended/full online learning in higher education. It is a qualitative study that employed in-depth interviews for data collection. The data collection procedure of this study employed (...) a judgmental sampling of twenty (20) lecturers who used Sakai/MOODLE Learning Management System (LMS) for teaching. It was observed that the extension of the modified TPACK framework to include ‘Ethics’ and ‘Accomplishment’ needs was in practical terms suitable and necessary for effective teaching and learning in higher education. It has been recommended that universities provide education on academic ethics and appropriate behaviours, sponsor lecturers in their academic careers and create an enabling environment for teaching and learning so that lecturers will get to the state of accomplishment in a blended learning milieu.
