Ozkal, Kudret; Tekkaya, Ceren; Cakiroglu, Jale; Sungur, Semra – Learning and Individual Differences, 2009
This study proposed a conceptual model of relationships among constructivist learning environment perception variables (Personal Relevance, Uncertainty, Critical Voice, Shared Control, and Student Negotiation), scientific epistemological belief variables (fixed and tentative), and learning approach. It was proposed that learning environment…

Dogru-Atay, Pinar; Tekkaya, Ceren – Journal of Experimental Education, 2008
The authors investigated the comparative effect of the learning cycle and expository instruction on 8th-grade students' achievement in genetics. They adopted the nonequivalent control group design as a type of quasiexperimental design. The experimental group (N = 104) received learning cycle instruction, and the control group (N = 109) received…

Tuncer, Gaye; Sungur, Semra; Tekkaya, Ceren; Ertepinar, Hamide – Hacettepe University Journal of Education, 2005
Patterns of consumption and production are not sustainable in developed/developing countries. In developed countries, the levels of pollution, especially those causing global change, are far too high and trends go in the wrong direction. In developing countries, there is too much strain on the local resource base, and this strain is increasing due…
