I consider and reject a specific criticism advanced by Korsgaard against virtue ethics and epistemology when these are conceived with the help of what she calls the image of the “Good Dog.” I consider what virtue ethics and epistemology would look like if the Good Dog picture of virtues were largely correct. I argue that attention to the features that make Korsgaard undermine the usefulness of virtues when conceived along the lines of the Good Dog picture reveals the opposite of what she claims. On the Good Dog picture, virtue ethics and epistemology are seen as more promising approaches to rationality than Korsgaard’s own advocacy of reflection.
The presented data and metadata include answers to questions raised in the questionnaire focused on the experience of teaching practicums and their role in the practical preparation of English language teachers at the Faculty of Arts, Charles University, as well as a basic quantitative analysis of the answers.
The analysis of the questionnaires shows that trainees are, in most cases, prepared for their teaching practicum both professionally and in terms of pedagogy and psychology, and the use of reflective teaching methods seems very useful. The benefits of the teaching practicum include, in particular, getting to know the real situation of teaching in secondary schools and working with a larger group of pupils, getting to know oneself as a teacher, gaining self-confidence, and becoming aware of one's own limits and areas for improvement. The downsides of the current system of teaching practice include mainly the low time allocation, the lack of integration of the practice in the curriculum, and the lack of involvement of the trainee in the daily running of the school (administrative work, supervision, meetings) and the lack of quality feedback from the faculty teacher.
At present, chlorophyll meters are widely used for a quick and nondestructive estimate of chlorophyll (Chl) contents in plant leaves. Chl meters allow to estimate the Chl content in relative units - the Chl index (CI). However, using such meters, one can face a problem of converting CI into absolute values of the pigment content and comparing data acquired with different devices and for different plant species. Many Chl meters (SPAD-502, CL-01, CCM-200) demonstrated a high degree of correlation between the CI and the absolute pigment content. A number of formulas have been deduced for different plant species to convert the CI into the absolute value of the photosynthetic pigment content. However, such data have not been yet acquired for the atLEAF+ Chl meter. The purpose of the present study was to assess the applicability of the atLEAF+ Chl meter for estimating the Chl content. A significant species-specific exponential relationships between the atLEAF value (corresponding to CI) and extractable Chl a, Chl b, Chl (a+b) for Calamus dioicus and Cleistanthus sp. were shown. The correlations between the atLEAF values and the content of Chl a, Chl b, and Chl (a+b) per unit of leaf area was stronger than that per unit of dry leaf mass. The atLEAF value- Chl b correlation was weaker than that of atLEAF value-Chl a and atLEAF value-Chl (a+b) correlations. The influence of light conditions (Chl a/b ratio) on the atLEAF value has been also shown. The obtained results indicated that the atLEAF+ Chl meter is a cheap and convenient tool for a quick nondestructive estimate of the Chl content, if properly calibrated, and can be used for this purpose along with other Chl meters., E.
