Effects of Cooperative Learning on Students’ Understanding of metallic bonding BurcinAcar and Leman Tarhan Presented by Natasha Cloughley
The Study • Ninth Grade students – all at approximately same level • Metallic bonding • 57 students from two different science classes in the same school • Same teacher • Cooperative approach • Teacher centred approach
Scientific conceptions • Student’s existing conceptions • Misconceptions • Metallic Bonding often not understood
Misconceptions • Physical properties of metal • Internal structures of metal • Confusion over metallic bonding and other chemical bonds • Nature of metallic bonds
Cooperative Learning • Small groups • Teacher asks leading questions • Teacher as facilitator not focus of lesson
Results • Concept test undertaken by students at completion • Experimental – mean of 78.60 • Control – mean of 54.33
