according to a basic prediction made by the revised hierarchical model (rhm,kroll & stewart, 1994), there is no l2 conceptual connection at the beginning stages of language learning as l2 learners mostly rely on l1 conceptual connections to retrieve the meaning of the l2 words.with increasing proficiency, however, there would be a direct access from l2 to the conceptual system. available litera...

As computers have become more powerful, the simulations and data processing applications that use them have become resource hungry, and, at the same time more complex. The complexity of simulations has increased in terms of the number of dimensions (from 1D to 2D to 3D), the set of equations being simulated (from one equation, to multiple equations in one domain, to multiple equations in multip...

The purpose of this qualitative exploratory study was to identify factors that influenced prospective and experienced secondary level science teachers’ reasoning as they evaluated or selected tasks to formatively assess their students’ understanding of scientific concepts. The analysis of the coded written responses revealed two categories of factors that influenced the teachers’ reasoning: (1)...

This paper follows the scenarios and task models debate by reviewing the contributions of task modelling and scenario based approaches from a cognitive perspective. A framework of cognitive affordances is introduced to discuss the merits and limitations of each approach. An extension of the modelling theme, generic task models, is proposed to augment the contribution of knowledge reuse to the d...

In this paper we present our first participation at RepLab Campaign. Our work is focused in two contributions. The first one is the use of an IR method to address Polarity and Filtering tasks. These two tasks can be seen as the same problem: to find the most relevant class to annotate a given tweet. For that, we applied a classical IR approach, using the tweet content as query against an index ...

This case study investigated how five novice teachers of French went about implementing tasks. In particular, the investigation aimed at finding out about implementational demands that imposed challenges for the teachers and how they coped with these challenges. The study also looked at the complementary relationship between implementational demands and task design factors and how these impact ...

iii ACKNOWLEDGEMENT It gives me a great pleasure to thank all those people who have helped me and contributed for the successful completion of this work. First of all, I would like to thank my advisor Dr. Ioan Raicu for giving me the opportunity to work under him on this project. The course I took under him triggered my passion in the field of distributed systems. His constant support and encou...

aim: it seems that positive outcomes resulting from the autonomy in the job, is dependent on a number of factors. autonomy means the interdependence and freedom of staff in planning and organizing work and it has different levels. the aim of current research is to investigate the role of task reflection in relation of autonomy and skill utilization. method: the research sample consisted of 324 ...
