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).

From Halos to Galaxies. VI. Improved Halo Mass Estimation for SDSS Groups and Measurement of the Halo Mass Function

The Astrophysical Journal
In ΛCDM cosmology, galaxies form and evolve in their host dark matter (DM) halos. Halo mass is crucial for understanding the halo–galaxy connection. The abundance-matching (AM) technique has been widely used to derive the halo masses of galaxy groups ...

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.

Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...

Improving the Determination of Supernova Cosmological Redshifts by Using Galaxy Groups

The Astrophysical Journal
At the low-redshift end ( z < 0.05) of the Hubble diagram with Type Ia Supernovae (SNe Ia), the contribution to Hubble residual scatter from peculiar velocities (PVs) is of similar size to that due to the limitations of the standardization of the SN Ia ...

Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species. In this

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

Journal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,
