The properties of reachable sets for linear dynamical systems for specified control sets are discussed. Iterative procedures for determining numerical approximations of the reachable set are suggested and methods of obtaining an admissible control function which transfers an initial state to as near a prescribed target as possible is described. The problem of teachability with multiple control ...

The purpose of this article is to introduce the thematics of my doctoral dissertation research. The study is a part of national KASVA -graduate school (2003-2006) which is funded by Finnish Academy. The aim of the research is to study teachability of the teaching material contents in higher engineering network-based mobile education (NBME). Teachability will be studied in authentic educational ...

Within learning theory teaching has been studied in various ways. In a common variant the teacher has to teach all learners that are restricted to output only consistent hypotheses. The complexity of teaching is then measured by the maximum number of mistakes a consistent learner can make until successful learning. This is equivalent to the so-called teaching dimension. However, many interestin...

Because a significant proportion of real-life L2 communication is problematic, L2 learners might benefit from instruction on how to cope with performance problems. Such instruction could include the specific teaching of’ communication strategies, which involve various verbal and nonverbal means of dealing with difficulties and breakdowns that occur in everyday communication. Opinions on the tea...

Teaching is inextricably linked to learning, and there are many studies on the complexity of teaching as well as learning in computational learning theory. In this paper, we study the complexity of teaching in the situation that the number of examples is restricted, especially less than its teaching dimension. We formulate a model of teaching by a restricted number of examples, where the comple...

This paper reports on a qualitative study that examined the perceptions of English teachers towards ‘teachability’ metaphorical language in Chilean EFL classrooms. The aimed at gaining better understanding teachers’ role metaphor classroom. A group six in-service participated this study. Data were gathered through semi-structured interviews, which addressed three broad dimensions: (i) views and...
