An Integrated Knowledge Framework to Characterize and Scaffold Size and Scale Cognition (FS2C)

Size and scale cognition is a critical ability associated with reasoning with concepts in different disciplines of science, technology, engineering, and mathematics. As such, researchers and educators have identified the need for young learners and their educators to become scale-literate. Informed by developmental psychology literature and recent findings in nanoscale science and engineering education, we propose an integrated knowledge framework for characterizing and scaffolding size and scale cognition called the FS2C framework. Five ad hoc assessment tasks were designed informed by the FS2C framework with the goal of identifying participants' understandings of size and scale. Findings identified participants' difficulties to discern different sizes of microscale and nanoscale objects and a low level of sophistication on identifying scale worlds among participants. Results also identified that as bigger the difference between the sizes of the objects is, the more difficult was for participants to identify how many times an object is bigger or smaller than another one. Similarly, participants showed difficulties to estimate approximate sizes of sub-macroscopic objects as well as a difficulty for participants to estimate the size of very large objects. Participants' accurate location of objects on a logarithmic scale was also challenging.     

The Indian and the researcher: Tales from the field

Conducting research in "native" communities is difficult. This article examines the tensions faced by an Indigenous researcher attempting to balance his identity as an Indian with his identity as an academic. Relying on field journals and personal experiences of change, the researcher explores how his attitudes toward the research participants and theories of authenticity changed over a period of time. Ultimately, there must be a way for Indigenous people to conduct rigorous research and maintain their Indigenous sense of self.     

The Civil Contract of Photography

A climate of political repression, formed by the Pitt Government in response to agitation by so‐called “radical” societies, surrounded debate on the Habeas Corpus Suspension Bill of 1794. Pitt employed rhetorical tactics such as manipulating evidence and disparaging motives in order to secure passage of this repressive measure. Pitt's tactics appear unjustified in the light of available historical evidence.     

Middle years and middle schools: an analysis of national policy

The terms ‘primary education’ and ‘primary schools’ were in use long before 1945. However, it was not until 1 April 1945 that primary education became the first of three statutory stages of the English education system. At that time, primary education faced an uncertain future because of the enormous problems it had inherited from the elementary school tradition. This article charts the early challenges that were faced during the years of World War II and immediate post-war period.
