Are geometric concepts of vectors bookable? An analysis of the didactic transpositions in mathematics textbooks
No full textIn Germany, the use of vectors is traditionally introduced in lower secondary education in Physics and in upper secondary education in Mathematics. In this curriculum, a geometric point of view plays an important, but somewhat unclear role whereas at the beginning of the Bachelor’s degree programmes structural-symbolic approaches dominate in courses like “analytic geometric and linear algebra”. Based on an analysis of Mathematics textbooks in upper secondary education from a point of view of geometry, differential geometry, and dynamical systems, the underlying geometric concepts are worked out as praxeologies. Some typical problems in working with vector geometry relate to the change between different conceptual models in the organisation of the textbooks

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
