Critical thinking: Essence for teaching mathematics and mathematics problem solving skills

  Critical thinking is a learned skill that requires instruction and practice. Mathematics education instructors at both the secondary and post-secondary levels can enhance students’ critical thinking skills by (i) using instructional strategies that actively engage students in the learning process rather than relying on lecture and note memorization, (ii) focusing instruction on the process of learning...

Einstein's equivalence principle has three further implications besides affecting time: T-L-M-Ch theorem (“Telemach”)

  General relativity is notoriously difficult to interpret. A "return to the mothers" is proposed to better understand the gothic-R theorem of the Schwarzschild metric of general relativity. It is shown that the new finding is already implicit in Einstein's equivalence principle of 1907 and hence in special relativity (with acceleration included). The TeLeMaCh theorem, named onomatopoetically...

Cross efficiency by using common weights for fuzzy data

  This paper firstly revists the cross efficiency evaluation method which is an extention tool of data envelopment analysis (DEA), then analyzes the potential flawes which happens when the ultimate average cross efficiency scores are used. In this paper, we consider the decision making units (DMUs) as the players in a cooperative fuzzy game, where the characteristic function values of coalitions are...
