Tools for Learning—Promoting Reflection for Student Teachers' Development of PCK

Journal of Research in Science Teaching, EarlyView.
ABSTRACT This paper investigates how the coherent integration of three different tools for reflection during a science methods course can contribute to student teachers' planning and enactment of science teaching, that is, their development of pedagogical content knowledge (PCK).

The Effect of Seductive Details on Knowledge Retention in Physics Videos: A Mixed Methods Study

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Research reports that interesting but irrelevant information, seductive details, in teaching material can impede learning. In science education, the inclusion of historical narratives in lessons to promote interest has been recommended but may hinder learning.

Discovery of Radio Jets in z ~ 2 Ultraluminous Infrared Galaxies with Deep 9.7 μm Silicate Absorption [PDF]

, 2007
Recent Spitzer observations have revealed a substantial population of z ~ 2 ultraluminous infrared galaxies (ULIRGs) with deep silicate absorption (τ9.7 > 1). This paper reports a 20 cm radio study of such a sample to elucidate their physical nature.

Inflating fat bubbles in clusters of galaxies by precessing massive slow jets [PDF]

, 2007
We conduct hydrodynamical numerical simulations and find that precessing massive slow jets can inflate fat bubbles, that is, more- or less-spherical bubbles, that are attached to the centre of clusters of galaxies. To inflate a fat bubble, the jet should

Multi‐Modal Instrument Performances (MMIP): A Musical Database

Computer Graphics Forum, EarlyView.
Abstract Musical instrument performances are multimodal creative art forms that integrate audiovisual elements, resulting from musicians' interactions with instruments through body movements, finger actions, and facial expressions. Digitizing such performances for archiving, streaming, analysis, or synthesis requires capturing every element that shapes

Numerical Simulations of Jets from Active Galactic Nuclei

Galaxies, 2019
Numerical simulations have been playing a crucial role in the understanding of jets from active galactic nuclei (AGN) since the advent of the first theoretical models for the inflation of giant double radio galaxies by continuous injection in the late ...

Optical Polarimetry of the Jets of Nearby Radio Galaxies. I. The Data [PDF]

, 2006
We present an overview of new HST imaging polarimetry of six nearby radio galaxies with optical jets. These observations triple the number of extragalactic jets with subarcsecond-resolution optical polarimetry. We discuss the polarization characteristics

Emotional (Dis/Un)entanglement in Becoming an Academic in the Neoliberal Era: Dialogising Transnational Accounts of Being, Thinking and Feeling

International Journal of Applied Linguistics, EarlyView.
ABSTRACT This paper explores the complex emotions and affective challenges that academics might experience in their journey of becoming within neoliberal higher education contexts transnationally. These are examined in entanglement with intricate social, ideological, political and racial factors across different stages of academic careers.
