TITLE OF TEACHING RESOURCE
3DMolSym (Molecular Symmetry)
Topics related to the resource
Chemical reactions, Chemical structure of molecules, closed formula of molecules’, bond structure, symmetry chart
Examples of learning objectives
-To be able to draws molecules’ symmetry structure.
-To be able to show molecule’s bond structure.
-To be able to see molecules’ features as 3D and try about them.
-To be able to indicate molecules’ closed formula.
Practical information regarding the use
of the site/simulation...
-Includes applications with regard to showing molecules’ 3D structure.
-Students can see molecules’s 3D features by trial
-Includes detailed applications about the molecule structure
Information about the class
Workgroup consist of 2013-2014 academic year’s 18 students of science teacher training department of Kırıkkale University
Suggestion for use
-Firstly, students were informed about the works
-3D simulation programme was analyzed, consist of 5 open ended question assessment instrument was developed. Before the using assessment instrument, pre-test was applied. Later, 3D simulation programme was runned and applications were done.
-Sample molecules’s closed formulas, bond structure and symmetry features were examined.
-Students implemented these via computer.
-Assessment instrument which was developed end of the work, was implemented as post-test.
-Results of two applications were compared.
-Besides, students’ remarks about the application was included.
Insights into student
use / thinking
-When analyzing the results of work, 3D applications have yielded positive results in constitute the closed formulas of molecules’, drawing bond structure and drawing symmetry.
-Students’ remarks about the applications;
-Reminds old informations (2 students)
-It is useful for chemistry teaching (6 students)
-Embodies issue ( 4 students).
-Visualizes issues (9 students)
-Provides practicality. (1 student)
-Facilitate to understand (7 students)
-Provide permanent learning (6 students)
-Shows falses clearly. (8 students)
-Provides feedback ( 5 students)
Teacher’s conclusions
-Teacher candidates state that appreciate the 3D applications and facilitate to understand more effective.
-It is indicated that 3D applications provides more effective learning with students’ active attendance.
