Knowledge from Testimony: Benefits and Dangers

Testimony is an important source of knowledge in many contexts, including that of education, but the notion of the teacher as testifier is not often discussed. Since much that is believed by individuals has come to them not from direct experience but by accepting the accounts of others, the trustworthiness of their interlocutors' testimonies, whether these be spoken, textual or electronic in form, is an important factor in determining whether or not they acquire true, justified beliefs. Testimonial trustworthiness is a combination of competence and sincerity, both of which tend to be high when a teacher testifies in her area of expertise. But in the world beyond the classroom there are situations in which the competence or sincerity of the testifier is low, so it is important that the learner acquires an epistemically‐virtuous, well‐attuned disposition towards testimony.

What can policy makers do to encourage integration of information and communications technology? evidence from the irish school system

Abstract

While most countries have invested heavily in information and communications technology (ICT) in education in recent years, the progress with integration of ICT into the teaching of other subjects has often been disappointing. How to encourage integration remains a serious question for policy makers and teacher educators. This article proposes some answers to that question, based on examination of data from the Irish school system. It suggests that ICT integration is associated with two kinds of teacher professional development: postgraduate ICT courses, and short in-service courses focused on specific integrated uses of ICT. The data reveal a strong association between the use of ICT in the school and the ICT usage of the school principal. Finally, it calls into question the use of pilot projects as the agents of change.

One in Three? Teachers' Attempts to Identify Low Self-Esteem Children

The maintenance of healthy self-esteem remains a central concern in pastoral care. It is almost taken for granted that we can identify low self-esteem in children based on the knowledge built up through day-to-day interactions. But self-esteem is essentially a personal perception, and one may ask, to what extent can another make reliable judgements about such a phenomenon? This study looked at the match between teachers' judgements of their pupils' self-esteem and the children's own self-reports. The teachers concerned were committed to self-esteem enhancement as an important goal of their teaching, but the findings indicate that when trying to identify low self-esteem children in their classes, they were frequently unsuccessful. These findings are discussed, and implications considered.
