Eliciting pupil perspectives in primary mathematics: possibilities and issues

This article considers various approaches to consulting primary pupils about mathematics. This is done first through a literature review and second by drawing on our experience of designing and piloting pupil consultation in collaboration with staff in one primary school. Our concern is with the utility and drawbacks of the methods used rather than with substantive issues. We conclude that useful information can be gained from both the planning process and outcomes, but caution must be exercised in interpreting pupil responses. Social processes are involved and the possibility of social desirability effects must be acknowledged. Finally, we indicate the usefulness of using different approaches together.     

Deconstructing learning in science—Young children's responses to a classroom sequence on evaporation

Five year old children's ideas were tracked by a range of means during and subsequent to a classroom sequence on evaporation. They held a range of conceptions which changed in complex ways across context and time. These could only be made sense of by moving outside traditional conceptual change interpretations to include broader notions of appropriation of language as a cultural tool, of personal and social narrative responses to features of the phenomena and the classroom setting, and the nature of science explanations. The findings are used to explore the relationship between social and individual perspectives on learning, and to question some assumptions underlying conceptual change research.     

‘His own peculiar style of hieroglyphics’: Hemingway,baseball, and the busher figure

ABSTRACT

The Busher figure was a recurring character found in both the mass market fiction and sports journalism of the early twentieth century—including the apprenticeship writings of Ernest Hemingway. The cultural significance of the Busher was explored in Hemingway’s early letters, high school and post-high school journalism, and a parody of Ring Lardner written for a Red Cross newsletter in 1918. In each instance, the Busher’s presence illustrated the figure’s role in linking the game of baseball to American culture.     

A joint learning approach with knowledge injection for zero-shot cross-lingual hate speech detection

Hate speech is an increasingly important societal issue in the era of digital communication. Hateful expressions often make use of figurative language and, although they represent, in some sense, the dark side of language, they are also often prime examples of creative use of language. While hate speech is a global phenomenon, current studies on automatic hate speech detection are typically framed in a monolingual setting. In this work, we explore hate speech detection in low-resource languages by transferring knowledge from a resource-rich language, English, in a zero-shot learning fashion. We experiment with traditional and recent neural architectures, and propose two joint-learning models, using different multilingual language representations to transfer knowledge between pairs of languages. We also evaluate the impact of additional knowledge in our experiment, by incorporating information from a multilingual lexicon of abusive words. The results show that our joint-learning models achieve the best performance on most languages. However, a simple approach that uses machine translation and a pre-trained English language model achieves a robust performance. In contrast, Multilingual BERT fails to obtain a good performance in cross-lingual hate speech detection. We also experimentally found that the external knowledge from a multilingual abusive lexicon is able to improve the models’ performance, specifically in detecting the positive class. The results of our experimental evaluation highlight a number of challenges and issues in this particular task. One of the main challenges is related to the issue of current benchmarks for hate speech detection, in particular how bias related to the topical focus in the datasets influences the classification performance. The insufficient ability of current multilingual language models to transfer knowledge between languages in the specific hate speech detection task also remain an open problem. However, our experimental evaluation and our qualitative analysis show how the explicit integration of linguistic knowledge from a structured abusive language lexicon helps to alleviate this issue.     

The impact of a chief planning officer on the administrative environment for planning

Institution-wide planning, to be effective, must have the support of key administrators. Presidents, vice-presidents, deans, and directors must feel that sufficient consensus can be reached on explicit goals to make comprehensive planning possible and worthwhile. While much has been written about the importance of CEO leadership in gaining broad support for planning, little has been said about the role of the chief planning officer in this regard. This paper, based on a national survey of administrators' views of planning, studies the relationship between having a chief planning officer and administrators' perceptions of campus planning. Its intended audience includes all those interested in institutional planning.Presented at the Thirty-first Annual Forum of the Association for Institutional Research, San Francisco, May 26–29, 1991.     

Two-choice conditional discrimination performance of pigeons as a function of reward expectancy,prechoice delay,and domesticity

In a discrete-trial two-choice conditional discrimination task, pigeons which received food for a correct choice following the presentation of one cue and water for a correct choice following another cue performed better than pigeons which received food and water equally often in both cases when delays of several seconds intervened between the conditional cue and choice stimuli presentations. These results suggest that feedback properties of reinforcer-specific expectancies can be important in conditional discrimination learning in pigeons. An additional finding was that wild-caught pigeons regularly exhibited a higher percentage of correct choices than domestic subjects.
