Development of Students’ Learning Strategies in Teaching Chemistry
E.Zorova, M.Akhmetov
Gradec Kralove, 2014
What is learning strategy?
• Sequence of mental operations:– representation of goals – intellectual styles for achievement of
learning results– an correction of thinking and
learning styles– Reflection methods & results in a
mind
• These operations can be doing in different mental styles– Visual style– Logical style – Symbolic style– Emotional style
What mental simulation use chemists?
Mental simulation:
Visual models
Chemical formulas end equations
Pictures and chemical models
Chemical phenomenon
A text
Mental simulation:Symbolic models
Chemical formulas end equations
Pictures and chemical models
Chemical phenomenon
A text
Why students have learning problems?
Problem of our research
Our hypothesis
• Students can achieve better educational results and improve their learning activity, if they will develop their learning strategies through learning chemistry

The beginning
Our attention
Pilot pedagogical experiment
• What students visualize in their minds if teacher says «Chemical element»?
What students Visualize Grades
1 group Model of atom Excellent
2 group Symbol of element
Good
3 group Periodic table Not good enough
Example of two ways for chemical calculations
Results of ’chemical problems’ solving

Conclusions & Perspectives on Future Research
• Chemists prefer visual models in their mind for solving chemical problems
• Specific of chemical thinking not enough reflected in textbooks
• Students need visual representation for better results of their learning
• Visual strategies allow students to achieve success in solving problems
• Technique for teaching chemistry through development learning strategies need to creation
