Tsaparlis, Georgios – Chemistry Education Research and Practice, 2016
In a previous publication, Jensen's scheme for the logical structure of chemistry was employed to identify a logical structure for physical chemistry, which was further used as a tool for analyzing the organization of twenty physical chemistry textbooks. In addition, science education research was considered for the study of the psychological…

Tsaparlis, Georgios – Chemistry Education Research and Practice, 2014
Jensen's scheme for the logical structure of chemistry is taken as reference to study the logical structure of physical chemistry. The scheme distinguishes three dimensions (composition and structure, energy, and time), with each dimension treated at one of the three levels (molar, molecular, and electrical). Such a structure places the outer…

Avramiotis, Spyridon; Tsaparlis, Georgios – Chemistry Education Research and Practice, 2013
This study is concerned with the effects of computer simulations of two novel chemistry problems on the problem solving ability of students. A control-experimental group, equalized by pair groups (n[subscript Exp] = n[subscript Ctrl] = 78), research design was used. The students had no previous experience of chemical practical work. Student…

Pappa, Eleni T.; Tsaparlis, Georgios – Chemistry Education Research and Practice, 2011
One way of checking to what extent instructional textbooks achieve their aim is to evaluate the questions they contain. In this work, we analyze the questions that are included in the chapters on chemical bonding of ten general chemistry textbooks. We study separately the questions on intra- and on intermolecular bonding, with the former…

Tsaparlis, Georgios; Kolioulis, Dimitrios; Pappa, Eleni – Chemistry Education Research and Practice, 2010
We present a programme for a novel introductory lower-secondary chemistry course (seventh or eighth grade) that aims at the application of theories of science education, and in particular of conceptual/meaningful learning and of teaching methodology that encourages active and inquiry forms of learning The approach is rigorous with careful use of…

Papaphotis, Georgios; Tsaparlis, Georgios – Chemistry Education Research and Practice, 2008
Part 1 of the findings are presented of a quantitative study (n = 125) on basic quantum chemical concepts taught in the twelfth grade (age 17-18 years) in Greece. A paper-and-pencil test of fourteen questions was used. The study compared performance in five questions that tested recall of knowledge or application of algorithmic procedures (type-A…

Papaphotis, Georgios; Tsaparlis, Georgios – Chemistry Education Research and Practice, 2008
Part 2 of the findings are presented of a quantitative study (n = 125) on basic quantum chemical concepts taught at twelfth grade (age 17-18 years) in Greece. A paper-and-pencil test of fourteen questions was used that were of two kinds: five questions that tested recall of knowledge or application of algorithmic procedures (type-A questions);…
