The effect of real and virtual laboratory experimentation on students’ understanding of electric circuits
Zacharia, Zacharias C.; Evagorou, Maria (University of Zilina, 2005)This study compared the effect of Virtual Laboratory Experimentation (VLE) - use of virtual apparatus and material to conduct an experiment on a computer - and Real Laboratory Experimentation (RLE) - use of real apparatus ... -
Effects of physical and virtual Experimentation on students conceptual Understanding in heat and temperature
Olympiou, Georgios; Zacharia, Zacharias C.; Papaevripidou, Marios; Constantinou, Constantinos P. (University of Cyprus, 2008)The purpose of this study was to compare the effect of Physical Manipulatives (PM), Virtual Manipulatives (VM), and two sequential combinations of PM and VM, on pre-service students’ understanding of scientific concepts ... -
Enhancing fifth graders understanding of complex ecosystems through a model-based approach utilizing stagecast creator
Papaevripidou, Marios; Constantinou, Constantinos P.; Zacharia, Zacharias C. (University of Zilina, 2005)We report a study in which we designed and implemented a curriculum within the context of ecosystems aimed at fostering scientific modelling skills and enhancing conceptual understanding among fifth graders through the use ... -
Managing teachers’ practicum in initial teacher preparation using an elearning platform
Zacharia, Zacharias C.; Evagorou, Maria; Constantinou, Constantinos P.; Papaevripidou, Marios; Kyratsi, Theodora (University of Zilina, 2005)This research study focuses on the development and evaluation of the Learning Space Platform as a resource for the improvement of the pre-service Teachers’ Practicum. The Teachers’ Practicum is a compulsory course for ... -
Modeling with stagecast creator: a video-case Study describing the process of Developing, evaluating and refining models of Accelerated motion in elementary school
Louca, Loucas; Zacharia, Zacharias C. (University of Cyprus, 2007)This paper describes a video case study from an elementary science/computer after-school club during which eleven sixth graders used Stagecast Creator™ to develop computer-based models of accelerated motion. Research in ... -
Physical meets virtual: blending physical and virtual manipulatives to improve understanding in the domain of light and shadows
Olympiou, Georgios; Zacharia, Zacharias C. (University of Cyprus, 2010)The purpose of this study was to compare the effect of experimenting with Physical Manipulatives (PM), Virtual Manipulatives (VM), and a blended combination of PM and VM, on undergraduate students’ understanding of scientific ... -
Symposium proposal computer-based modeling in science: the case of stagecast creator
Constantinou, Constantinos P.; Louca, Loucas; Nicolaou, Christiana Th.; Papaevripidou, Marios; Zacharia, Zacharias C. (University of Zilina, 2005)There is a longstanding awareness of the need to help students learn about models and modeling in science, and computer-based programming environments are promising tools for this. A computer program can be a model of a ... -
