The Beer-Lambert law is a fundamental relationship in chemistry that helps connect macroscopic experimental observations (i.e., the amount of light exiting a solution sample) to a symbolic model composed of system-level parameters (e.g., concentration values). Despite the wide use of the Beer-Lambert law in the undergraduate chemistry curriculum…

Student-generated drawings are known to be effective in building and revealing students' conceptions of chemistry. Some chemistry concepts, moreover, include changes and processes that cannot be merely represented by static drawings. Computer-based animations are needed to represent the dynamics. In this study, 25 chemistry student teachers, who…

Background: Studies comparing the effect of dynamic and static visualization suggest a predominantly positive effect of dynamic visualization. However, the results of individual comparisons are highly heterogeneous. In this study, we assess whether dynamic visualization (3D models and animations) used in the experimental group has a stronger…

The comparative analysis of different meanings of Chemistry is carried out, taking in account philosophical, didactic, psychological and socio-cultural aspects. The issue is discussed in terms of the concurrent existence of two different subsystems referred both to Science and Education which can be found in presentations of chemistry knowledge.…

This mixed method study investigation uses eye tracking and qualitative analysis to investigate the impact of animation variation and visual feedback on the critique of submicroscopic representations of experimental phenomena. Undergraduate general chemistry students first viewed an experimental video of a precipitation or oxidation reduction…

This study aimed to explore the beliefs and attitudes of 36 science teachers (biology, physics and chemistry) in six high schools in Ankara towards the use of Interactive White Boards (IWB). Of these, three teachers from each school were chosen for interview and classroom observations according to their questionnaire results with purposeful…

Given that students are constantly communicating and documenting special experiences in their social and private lives with digital devices, we suggest that this behavior could be used to record and deepen learning experiences-such as visualizing reactions at the molecular level-in a chemistry class. An example would be the creation of stop-motion…

This research aimed at describing the effectiveness of the macromedia flash based inquiry learning in improving students' concept understanding in chemistry learning. It was an experimental research with post-test only design. The population was the eleventh-grade science students of state high school 5 Yogyakarta, Indonesia. The sample in this…

Students' understanding of the orbital concept has been subject to considerable research and debate and often found at variance with a quantum mechanical ideal. Could it be the case that orbitals as actually used by practising chemists in teaching and research also differ from that ideal? Our experience shows that this might often be the case.…

The purpose of this study was to examine the changes in 19 preservice chemistry teachers' understandings of the structure of matter, including the aspects of the physical states of matter, the physical composition of matter, and the chemical composition of matter, before, immediately after, and months after they received a specific instruction.…

This paper discusses what chemistry students might see while working with animations found on the Internet and how these electronic illustrations can potentially interact to reinforce rather than resolve misconceptions about chemical principles that a student may possess. The Daniell voltaic cell serves as an example to illustrate the ways in…

This study investigates the effects of using both specific labels and diagrammatic arrows in the animation of salt dissolution. Four different versions of the animation served as treatments that were developed based upon principles of educational technology and cognitive psychology. The researchers studied the effects of spatial ability (high or…

A Particulate Nature of Matter Evaluation Tests was used to explore the effect of computer animations depicting the particulate nature of matter on (n=400) college students' mental models and comprehension of chemical phenomena. Treatment groups received significantly higher conceptual understanding scores than did the control group. (30…
