Eye-tracking verification of the strategy used to analyse algorithms expressed in a flowchart and pseudocode

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode and flowchart. The eye-tracking data resulted in both qualitative (films registering the gaze paths) and quantitative measures, which allowed the detection and interpretation of the differences in the task-solving strategies between those who found the correct answer and those that did not. The results confirmed a hypothesis that use of the formal notation characteristic of a programming language for presenting algorithms is often a practical difficulty in the process of solving even simple tasks. This study opens a new direction of research; they show that eye-tracking technology can be used to optimise the educational process of learning programming.     

Christian religious education and the development of moral virtues: a neo-Thomistic approach

ABSTRACT

This article explores the implications for Christian religious education of the theory of moral virtues formulated by Thomas Aquinas and developed by the contemporary Neo-Thomists. The analysis is divided into two parts. The first part introduces Thomistic virtue theory and presents cardinal virtues crucial for Thomistic ethics: prudence, justice, temperance and fortitude, as the reference points for moral education. This part also includes analysis of the relationship between cardinal and theological virtues, leading to the conclusion that Christian religious education also requires the development of theological virtues. The second part explores, through Thomistic theory, what factors condition the development of a person’s moral character (i.e. his/her moral virtues) and what those factors mean for supporting moral education within Christian religious education, initially within the context of Polish schooling. Particular attention is given to three issues: introducing the concept of responsibility for community members, introducing knowledge of moral virtues, and building a relationship with God.     

Academic self-concept and achievement in Polish primary schools: cross-lagged modelling and gender-specific effects

This study reports relationships between general academic self-concept and achievement in grade 3 and grade 5. Gender-specific effects were investigated using a longitudinal, two-cycle, 3-year autoregressive cross-lagged panel design in a large, representative sample of Polish primary school pupils (N?=?4226). Analysis revealed (a) reciprocal relations between general academic self-concept and achievement over time but the influence of prior achievement on self-concept was stronger; (b) on average, levels of both constructs declined over time; (c) gender differences were not observed in longitudinal relations (i.e. cross-lagged, autoregressive and intra-wave correlations); (d) girls demonstrated higher mean levels of academic achievement at both grades; and (e) average level of general academic self-concept was not gender differentiated in grade 3 but decreased more for girls. These results are discussed in the light of the theoretical and practical implications.     

Language Attitudes and Community Engagement: Diwan–The Breton Immersion High School Through the Eyes of Its Pupils

This article is based on long-term participant observation and interviews with pupils and graduates of the Diwan immersion high school in Brittany, France. With reference to the theory of communities of practice, this article shows how the education in the Breton immersion school can influence a knowledge of the minority language and the young peoples’ engagement with the protection of the Breton language. This article presents the social and cultural capital received through the learning of the Breton language; the distinction between Diwan pupils and people from outside the community; and the gradual formation of a collective new Breton-speakers identity. The sociolinguistic prognostic shows that in a few dozen years the only Breton speakers will be Breton learners. The use of Breton depends thus on having knowledge of it and on finding a community in which this language acts as the benchmark for the creation of a Breton identity.     

STUDENTS’ UNDERSTANDING OF EQUILIBRIUM AND STABILITY: THE CASE OF DYNAMIC SYSTEMS

Engineering students in control courses have been observed to lack an understanding of equilibrium and stability, both of which are crucial concepts in this discipline. The introduction of these concepts is generally based on the study of classical examples from Newtonian mechanics supplemented with a control system. Equilibrium and stability are approached in different ways at the various stages of a typical engineering syllabus: at the beginning, they are mostly dealt with a static point of view, for example in mechanics, and are subsequently handled through dynamic analysis in control courses. In general, there is a little clarification of the differences between these concepts or the ways in which they are linked. We believe that this leads to much confusion and incomprehension among engineering students. Several studies have shown that students encounter difficulties when presented with simple familiar or academic static equilibrium cases in mechanics. Our study investigates students’ conceptions and misconceptions about equilibrium and stability through a series of questions about several innovative non-static situations. It reveals that the understanding of these notions is shaken when the systems being studied are placed in inertial or non-inertial moving reference frames. The students in our study were particularly uncertain about the existence of unstable equilibrium positions and had difficulty in differentiating between the two concepts. The results suggest that students use a velocity-based approach to explain such situations. A poor grasp of the above fundamental concepts may result from previous learning experiences. More specifically, certain difficulties seem to be directly linked to a lack of understanding of these concepts, while others are related to misconceptions arising from everyday experiences and the inappropriate use of physical examples in primary school.     

Dimensional Stability and Moisture Properties of Gap-Fillers Based on Wood Powder and Glass Microballoons

ABSTRACT

Conservation of wooden objects exposed outdoors is extremely difficult and complex due to their constant exposure to fluctuating weather conditions and biological degradation. Filling the gaps in such objects requires the use of specific materials that in particular can adapt to changes in wood dimensions in response to humidity variations. Various materials have been used so far for filling voids in wooden artefacts but none of them was entirely suitable. Therefore, the authors have attempted to provide the basic characteristics of the selected commonly used filling materials based on pine wood powder or glass microballoons as fillers and Paraloid® B-72, Klucel® G, or glutin glue as binders, as the first step in research aiming at developing new and more appropriate gap-fillers. Special attention was paid to the dimensional stability of filling materials upon drying and exposure to water vapour and liquid water. The overall results indicate that among the examined fills those consisting of Paraloid® B-72 and glass microballoons revealed best properties as they were relatively dimensionally stable upon drying and exposure to moisture – despite high absorption of water – and were quite easy to finish. Generally, better properties were observed for filling materials containing higher concentrations of adhesives and these materials will be modified in the next step of the research. Since the main drawbacks of the examined gap-fillers were low water resistance, poor dimensional stability upon drying or exposure to water vapour or liquid water, and fragility or friability, future research into their modification will head towards improvement of the above-mentioned properties.
