title: Considering pedagogical content knowledge in the context of research on teaching: An example from technology

authors: Jones, Alister

abstract: When thinking about teaching, the pedagogical content knowledge of teachers cannot be ignored. We argue that pedagogical content knowledge is a major determiner of teaching practice and is central to teachers’ curriculum decision-making at the classroom level. This paper takes a sociocultural perspective on the importance of developing teachers’ pedagogical content knowledge. From our classroom-based research in technology education and the past research we propose a model of pedagogical content knowledge with seven characteristics that we believe are important for effective teaching.

title: 15 yr of interstellar neutral hydrogen observed with the Interstellar Boundary Explorer

authors: Galli, A

abstract: The interactions of our heliosphere with the surrounding local interstellar medium (LISM) lead to a range of observable phenomena such as energetic neutral atoms (ENAs) from the boundary regions of the heliosphere and the influx of interstellar neutrals (ISNs) into the inner solar system. Hydrogen is the dominant neutral species in the LISM, but due to ionization and radiation pressure, only a fraction of the ISN H atoms reach the inner solar system close to Earth. Monitoring this signal therefore provides observational constraints on our assumptions of the LISM and the solar-activity-dependent loss processes inside the heliosphere. The IBEX-Lo instrument on board the Interstellar Boundary Explorer has been the only instrument so far to measure ISN H atoms directly, together with ISN D, He, Ne, O, and ENAs in the energy range from tens of eV to 2 keV. This study covers 15 yr of IBEX-Lo ISN H observations, i.e., more than one solar cycle and includes two solar minima when the ISN H signal in IBEX-Lo is strongest. Despite the very intense ISN He signal, the ISN H signal can be retrieved with appropriate knowledge of the instrument, choice of optimum observation season, and supporting modeling. The retrieved ISN H signal shows a clear anticorrelation with solar activity. The resulting ISN H maps are available in orbit format and in ecliptic coordinates and will be the basis for future more detailed comparison with heliosphere models.

title: In service provision for teachers of Maori language and teachers who teach through the medium of Maori: A working model reviewed

authors: Johnson, Diane

subjects: te reo Māori

abstract: This paper reports on the design, administration and effectiveness of an in-service programme designed by the University of Waikato in partnership with the New Zealand Ministry of Education. The programme aims to: improve language proficiency; assist with the interpretation and implementation of Māori curriculum statements; address issues involved in teaching Māori and teaching through the medium of Māori; assist with lesson planning and lesson delivery, materials development and testing and assessment.
