Learning from the worked examples is the main way to gain knowledge. According to the similarity-based theory, performance is enhanced when there are at least two or more examples presented in the process of learning from the worked examples, while the explanation-based theory holds that one example is enough so long as it is a case in point. Based on ACT-R, Anderson and his colleagues put forward four-stage superimposed model, and Sweller presents the cognitive load theory from the perspective of cognitive resources. These four theories direct the empirical study in the worked example learning and teaching practice from different angles. [ABSTRACT FROM AUTHOR]

Three-to-six/seven-year-old period is an important stage for preschoolers to develop their spatial intelligence. Rich experience of spatial activities can promote the formation of neural circuits related o spatial thinking and arouse children' s interest in spatial activities, and bridge the gender gap. In his period, parents and teachers should provide more opportunities for preschoolers o play construction games, design games and map games with effective language instructions, encourage children o solve spatial problems with the help of hand gestures, allow children o have free sensation movement activities, and add the content concerning spatial intelligence o cartoons and children' s book. All of these are effective ways o develop pre-schoolers' spatial ability. [ABSTRACT FROM AUTHOR]
