the kinematics and dynamics of two industrial cooperating robots are presented in this paper. the noc (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. the joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. to this end, minimizing the cr...

This project used techniques from problem-based learning to aid students in developing a technology-based science lesson. In this case, the " problem " students were asked to solve, was that of combining curriculum knowledge and pedagogi-cal skills to incorporate computer graphics animation technology within a science lesson and then teach the lesson to secondary students. Student artifacts as ...

This study examined situational fluctuations in student teachers’ (N = 120) development self-efficacy during a three-week teaching practicum Switzerland. Situational measurements (state) were assessed six-lesson unit on written argumentation. Results showed that intra-individual state increased the practicum. However, multilevel regression models indicated fluctuated considerably with approxima...

This paper documents the design, implementation, and evaluation of an online learning community (OLC), within Republic Ireland, which set out to support student teachers in a hybrid space during their school placement experience. Guided by qualitative research, data collection methods included interviews analysis students’ forum postings. Key findings illustrated that OLC provided valuable cont...
