Argumentation skills are highly valued in both education and business. As a process, participating in argumentation helps a person to develop their meta-cognitive and higher-order thinking abilities. This paper reports on empirical results on middle-school students’ changes in attitudes towards argumentation as part of an ongoing design-based research study. Past attempts by researchers to fost...

We examine the M-theory version of SQCD which is known as MQCD. In the IIA limit, this theory appears to have a supersymmetry-breaking brane configuration which corresponds to the meta-stable state of N = 1 SU(Nc) SQCD. However, the behavior at infinity of this non-supersymmetric brane construction differs from that of the supersymmetric ground state of MQCD. We interpret this to mean that it i...

In this paper, we extend our previous approach to memory in the DALI language from facts to (sets of) rules, and we extend their management by introducing operators for reasoning about the context and agent is involved in, and about modules that should be associated to that context in the working memory. We exploit and extend our past work where we introduced meta-axioms for run-time self-check...

We re-examined the effect of teaching and learning with technology on student cognitive and affective outcomes using the meta-analytic technique. Screening studies obtained from an electric search of databases such as PsyInfo and ERIC resulted in 58 studies (1997-2011). Overall, effect sizes were small to moderate across the cognitive and affective outcome measures. Specific teaching/learning c...
