What troubles early childhood educators in New Zealand: a 20-year cross-sectional study of ethical difficulties in early childhood practice

For more than 20 years, the New Zealand early childhood (EC) sector has had guidance about how to deal with situations of ethical difficulty in daily practice through the ECE Code of Ethics. This paper reports on three surveys undertaken at 10-year intervals that sought to understand EC educators’ experiences of such situations, and how they addressed them within their EC settings. An analysis of educators’ stories of ethically troubling situations from the three data-sets traced shifts and similarities in the content reported, and in how educators responded to these challenges over the two-decade period. We situate this analysis alongside changes in the New Zealand ECE policy context during the same time frame. We argue that a connection exists between the reported situations and teachers’ responses to them, and changes within the policy and professional context of daily EC practice.     

Encouraging Knowledge Transfer in Food Science and Nutrition Education: Suggestions from Cognitive Research

For several decades, cognitive psychologists have been studying how we learn, and from this work it becomes possible to identify ways to help students learn in the classroom effectively. Importantly, this work does not just inform how to memorize facts, but also how to learn complex material in a way that allows students to apply what they are learning in future situations. The laboratory to classroom model used by many researchers to apply cognitive psychology to real educational situations, such as classroom learning and students’ independent studying, is described first. Then the focus turns to important issues within education, such as students’ ability to transfer knowledge to new situations and understand complex material. Finally, three learning strategies are discussed (concrete examples, elaborative interrogation, and retrieval practice) that instructors can implement to help students to both acquire knowledge and apply it to new situations, integrating examples from food science and nutrition.     

Teachers’ intuitive interaction competence and how to learn it

In the study that forms the basis of this article, I have shed light on various aspects of how the intuitive actions of the teacher appear in the classroom, and also drawn attention to the tacit aspect of this kind of actions. Furthermore, I have discussed how these can be seen as a significant part of the teacher’s intuitive action competency. The investigation also discusses how teachers’ education can facilitate the development of this competency. The study argues that what is crucial to how the teacher handles unexpected situations is that he, based on his experience, manages to face new situations with enough creativity to break free from established patterns across situations, and act in an appropriate manner according to the emerging situation. Data are collected by using video recordings, applying videography as a methodological approach. Four teachers have been videotaped in the classroom, in total 45–50 h.

Sameness and Difference in Transfer

Discussions about transfer have mainly dealt with how people manage to do something in a situation thanks to having done something similar in a previous situation. From an educational point of view, however, it appears more fruitful to consider the case when the learner, having learned to do something in 1 situation, might be able to do something different in other situations, thanks to perceived differences (and similarities) between situations. The case is made for widening the focus of attention to how situations are related through differences (and similarities).

Experience is Not The Whole Story: The Integral Role of the Situation in Dewey's Democracy and Education

The central objective of Dewey's Democracy and Education is to explain ‘what is needed to live a meaningful life and how can education contribute?’ While most acquainted with Dewey's educational philosophy know that ‘experience’ plays a central role, the role of ‘situations’ may be less familiar or understood. This essay explains why ‘situation’ is inseparable from ‘experience’ and deeply important to Democracy and Education’s educational methods and rationales. First, a prefatory section explores how experience is invoked and involved in pedagogical practice, especially experience insofar as it is (a) experimental, (b) direct, and (c) social‐moral in character. The second and main section on situations follows. After a brief introduction to Dewey's special philosophical use of ‘situation’, I examine how situations are implicated in (a) student interest and motivation; (b) ‘aims’ and ‘criteria’ in problem‐solving; and (c) moral education (habits, values, and judgements). What should become abundantly clear from these examinations is that there could be no such thing as meaningful education, as Dewey understood it, without educators’ conscious, intentional, and imaginative deployment of experience and situations.
