Awareness of the knowledge of learning partners is not always sufficiently available in collaborative learning scenarios. To compensate, the authors propose to provide collaborators with partner knowledge awareness by means of a visualization tool. Partner knowledge awareness can be used to adapt messages toward the partner. This study investigated the cognitive consequences of message adaptation on producers. The authors chose a simulated collaboration scenario in order to dissociate the producer effect from recipient and collaboration effects. Results on 42 participants that had been randomly assigned to either the partner knowledge awareness condition (partner and own knowledge visualized) or the control condition (only own knowledge visualized) are reported here. Participants in the partner knowledge awareness condition adapted their contributions according to the visualized partner's knowledge and benefited with regard to the acquisition of elaborated knowledge. 相似文献

Plastid atpB/rbcL intergenic spacer sequences were obtained from 21 selected taxa and
one hybrid of Anemoninae (Anemone, Pulsatilla, Hepatica) and compared with Ficaria (Ranun-
culinae) as an outgroup. From the resulting matrix (1226 bp) a single most parsimonious tree was
obtained (Fig. 1 ). The branching of this tree is confirmed by many informative indels and appears
largely congruent with past plastid restriction analyses. Several new taxa are added. The monophyly
of the Anemoninae and their early split into two major clades is supported: clade I with the chromo-
some base number x = 8, clade Ⅱ with the reduced x = 7. Clade Ⅰ is made up of the basal Pulsatilla
and the Rivularis + Vitifolia groups. The Multifida group links to the crown groups Coronaria,
Blanda and Nemorosa. Clade Ⅱ consists of the basal Dichotoma group, followed by Hepatica, and
finally by the N. Hemisphere Narcissiflora and the S. Hemisphere Antucensis groups as sisters. The
problems of the Anemoninae ancestry, phylogenetic differentiation, and recent attempts for systemat-
ic classification are critically discussed. In view of the still incomplete sampling of DNA data, aconservative and informal approach to classification problems is recommended. 相似文献
