The second year of life as a developmental turning point: Implications for «sensitive» caretaking

In the context of the transactional view on development, important changes in the second year of life are highlighted which demand parental adaptations in caregiving practice. The discontinuous growth of enriched cognitive functions in the toddler, as exemplified by Piagetian theory on development of intentionality and symbolic thinking and by recent findings about the emergence of self-awareness and mastery-motivation, meshes with changes in caregiving dimensions. The caregiver, seen as a catalyst for the development of cognitive and social competence must adjust himself to the developmental tasks the infant is coping with. The concept of sensitivity is examined in terms of two important aspects: the social and the didactic. From a Vygotskian standpoint, didactic strategies are very important for cognitive competence. Parents have to facilitate self-initiated learning and to adjust to the infant’s increasing cognitive functions. The influence of a didactic «matching» on overall parent-infant interaction quality, and especially on the quality of attachment, is stressed.

The role of student-generated externalizations in strategic multimedia learning and how current (web-)technology fails to support learner engagement

In two studies, we investigated how learning strategies can support learning from multimedia. In the first study, 112 students learned from a web-based learning environment. On the basis of a strategy, one group of students took typewritten notes. The second group of students wrote a summary. Producing typewritten notes did not benefit learning any more than writing a summary. In the second study, 100 students learned the same subject matter from print. On the basis of a strategy, the first group produced written notes, the second group highlighted, wrote notes, and produced sketches. The third group wrote a summary. The students who highlighted, wrote notes, and produced sketches outperformed the other students. The students who produced written notes only did not learn more successfully than those who wrote a summary. The results suggest that externalizations in general and sketches in particular may play an important role in multimedia learning.
