Science concept learning by English as second language junior secondary students

Recent Chinese migrant students from Taiwan studying science in two Australian secondary schools were found to explain the meanings of selected science concept labels in English by translating from Chinese. The research strategy involved interviewing the students concerning their recognition and comprehension of the science concept labels firstly in Chinese and then in English. Mean recognition and comprehension scores were higher in Chinese than in English, with indications that Chinese language and science knowledge learnt in Chinese deteriorated with increasing time of residence in Australia. Rudimentary signs of the students being able to switch between Chinese and English knowledge bases in science were also found. Implications for teaching science to ESL students and suggestions for further research are discussed.

Empowering teacher leadership: a cross-country study

ABSTRACT

The contextual, purpose-driven challenges facing schools and school systems across the world call for creative and innovative responses to revitalize school practices. The process of revitalization will require new thinking, new mindsets within an adaptive school culture and new leadership roles (formal and informal). Often the perception of leadership held within a school is that it is the province of the principal; however, if we move from a top-down model of leadership we can ulitize the capacity of others within to lead the learning. To enable this to happen, teacher leaders need to work with agency and principals need to nurture and grow their formal and informal leadership roles within the school. For many teachers, the question is how they can establish and commit to leadership roles and responsibilities within the school community while remaining in a teaching position. This case study examined the practices of teachers as they experienced leadership across three cross-cultural contexts: Colombia, Canada and Australia. It presents exemplars of teacher leadership in action and provides images of teacher leadership as enacted in addition to an understanding of the factors that were important in supporting their leadership actions.     

Exploring the boundaries: A study of multiple classroom learning environments

The study of learning environments has developed into a productive field of research in science education. Initially, the design and application of classroom perceptual measures of particular dimensions of science classrooms attracted much attention. More recently, such instruments have been used alongside of qualitative techniques to provide a richer understanding of sub-environments. We continue this trend in the present interpretive study by exploring the nature of multiple environments within a middle school classroom from the different perspectives of teacher, student and participant observer. In particular, we examine the activity settings of lectures and group work, as well as the issues of learning and assessment. We conclude by arguing that teachers need to adopt procedures that enable them to identify and plan for multiple environments.     

A study of the validity of four types of student ratings of college teaching assessed on a criterion of student achievement gains

The purpose of the study was to investigate relationships between student ratings of college teaching using four types of student rating instruments and pre- vs. post-student achievement gains in 36 sections of an undergraduate analytic geometry and calculus course. Student rating instruments used varied according to type of items (high vs. low inference) and focus (students rating their own perceived growth vs. rating the instructor). Data were collected on 799 students (66% freshmen; 16% sophomore; and 15% juniors) at the University of Florida, and relationships were analyzed using the Pearson product-moment correlation technique. Significant relationships were not found between student ratings and student achievement.     

Studieren an der Berufsakademie oder an der Universität, Fachhochschule oder Pädagogischen Hochschule?

Beim übergang von der Schule auf die Universit?t müssen sich Abiturienten u.a. für einen bestimmten Hochschultypus entscheiden. Der Fokus in diesem Beitrag liegt auf der sogenannten Berufsakademie, die in einigen Bundesl?ndern eine interessante, aber wenig beachtete Alternative zu Universit?t, Fachhochschule und P?dagogischer Hochschule darstellt. Anhand einer gro?en L?ngsschnittstudie, die in Baden-Württemberg durchgeführt wird, werden der Leistungsstand, der famili?re Hintergrund, die beruflichen Interessen und die Studienwahlmotive von (künftigen) Studierenden an den verschiedenen Hochschultypen untersucht. Berufsakademien erwiesen sich insbesondere für Abiturienten mit weniger günstigem famili?ren Hintergrund und dem Wunsch, rasch finanziell unabh?ngig zu sein, sowie für Absolventen beruflicher Gymnasien als attraktive Alternative zur Universit?t. Berücksichtigt man die schulische Herkunft (berufliches vs. allgemeinbildendes Gymnasium), so fanden sich ?hnliche kognitive Eingangsvoraussetzungen bei Studierenden wirtschaftswissenschaftlicher F?cher an Berufsakademie, Fachhochschule und Universit?t.
