In this paper, we present flexMLfD, a robot independent and task independent demonstration learning system that supports a variable number of robot learners. Our approach is based on the Confidence-Based Autonomy (CBA) demonstration learning algorithm, which provides the means for a single robot to learn a task policy through interaction with a human teacher. The generalized representation and ...

Solutions to complex tasks often require the cooperation of multiple robots, however, developing multi-robot policies can present many challenges. In this work, we introduce teaching by demonstration in the context of multi-robot tasks, enabling a single teacher to instruct multiple robots to work together through a demonstration of the desired behavior. Within this framework, we contribute two...

This study considers how students’ perceptions of their teachers’ communicative style, particularly the extent to which teachers are perceived to support students’ autonomy and to provide useful feedback about students’ learning progress, are related to students’ extrinsic and intrinsic motivational orientations. It also examines the link between these variables and various language learning ou...

Although many researchers acknowledge that Assessment for Learning can significantly enhance student learning, the factors facilitating or hindering its implementation in daily classroom practice are unclear. A systematic literature review was conducted to reveal prerequisites needed for Assessment for Learning implementation. Results identified prerequisites regarding the teacher, student, ass...

This article analyzes the possible effects that continuous head teacher turnover can have on school organizational climate. The article first presents the transformations that the Italian school system has experienced in the last fifteen years since the introduction of the autonomy law, and then provides a brief overview of the main theories regarding the organizational climate making a compari...

There are various ways of learning. I would like to listen more to the voices of the learners as individual persons, not only as students of English. I have decided to introduce portfolios into my classes because they can make language learning more visible. One of the perceived advantages of portfolios for students is that they can become autonomous learners. Autonomy, which can be a general e...

this study investigated the characteristics of effective secondary school iranian efl teachers from students’ and teachers’ perspectives. to this end, 376 junior secondary school students and 32 efl teachers teaching at various iranian secondary schools participated in the study. a validated open-ended questionnaire was distributed among the student and teacher participants and asked for their ...

Research has shown that teachers’ autonomy support and provision of structure relate to students’ agentic behavioral engagement. Moreover, engagement elicits higher teacher sup...

We present Confidence-Based Autonomy (CBA), an interactive algorithm for policy learning from demonstration. The CBA algorithm consists of two components which take advantage of the complementary abilities of humans and computer agents. The first component, Confident Execution, enables the agent to identify states in which demonstration is required, to request a demonstration from the human tea...
