But is this method also applicable in instructional settings using modern communications media? This paper is an attempt to find. an answer to the question: By what means is the investigation of the formation of theoretical thinking realizable through the application of the causal-genetic method in instructional settings using hypermedia and distance learning? However, a closer examination of the question itself shows that there are three interrelated aspects, namely: the investigation and formation of theoretical thinking; distance learning using modern communications media; the causal-genetic method. It will be shown that in a formation experiment learning with a hyper-media- educational program, which is based on the theory of learning- activity,' students reach a new level of cognitive development which is characterized by the growing ability of complex and dialectical thinking Y1 - 2004 ER - TY - JOUR A1 - Kahlert, Joachim A1 - Cech, Diethard A1 - Giest, Hartmut A1 - Hempel, Marlies A1 - Wittkowske, Steffen A1 - Hartinger, Andreas T1 - Sachunterricht nach PISA und IGLU Y1 - 2004 SN - 3-7065-4020- 7 ER - TY - JOUR A1 - Giest, Hartmut A1 - Lompscher, Joachim T1 - Formation of learning activity and theoretical thinking in science teaching Y1 - 2003 ER - TY - JOUR A1 - Giest, Hartmut T1 - Aneignung und Entwicklung von Begriffen im Sachunterricht Y1 - 2003 ER - TY - JOUR A1 - Giest, Hartmut T1 - Der Einfluss der Variablen Unterricht und Alltag auf die Entwicklung des Begriffes "Arbeit" im Grundschulalter Y1 - 2003 SN - 3-8100-3928-4 ER -
