Offering help functions is a standard feature of computer-based interactive learning environments (ILE). Nevertheless, the effectiveness of learners’ use of help facilities has been subject to extensive debate. In this paper the issues of effectiveness of help and the impact of learner-related factors are addressed in an ILE for plant identification. We report first explorative data from a regu...

The aim of the present study is to investigate the effects of bullying, suicida...

The gauge coupling constant unification at the low (O(TeV)) scale can be obtained just in four dimensions, without help of the power like renormalization group evolution in extra dimensions, due to the presence of some extra particle states at intermediate scales. We show explicit examples of such extra states in the range of 100 GeV – 1 TeV which can be easily observed on future colliders and ...

Four teams of students, each one made up of a victim, model, and two observers, staged standard collapses in which type of victim (drunk or ill), race of victim (black or white) and presence or abse...
