Original Title:
Κατανοώντας την έννοια της περιεκτικότητας διαλυμάτων με την μέθοδο της καθοδηγούμενης ανακάλυψης (GUIDED DISCOVERY)
Translated title:
Understanding the concept of solution content with Guided Discovery (GUIDED DISCOVERY)
Summary:
We have observed that guided discovery can benefit students in the cognitive domain in Chemistry of 1st year Lyceum regardless of their sex (male or female) and prior knowledge
The teaching was divided into two closely related units which were:
UNIT 1: Content of solutions
UNIT 2 : Concentration of solutions (dilution, condensation & mixing of solutions).
The implementation of the research work was conducted in the followings steps:
1. Creation of worksheets, exit cards and power point presentations.
2. Utilization of 4 classes of the 1st grade of senior high school in our research inform of 2 experimental groups and 2 controls groups.
3. Conventional teaching methods were used in the control groups however a twenty-minute tutorial with power point presentation followed by research with guided discovery were used in the experimental groups
4. At the end of each research, each group received a 5-minute exit card under the supervision of Doctor Kouloumbaritsi.
5. A significant statistical difference was not observed between the benefits of the experimental groups in comparison with the control groups.
6. Not found significant statistical difference between boys and girls.
Consequently we reached the conclusion that in order to be more successful guided discovery, should be thoroughly organised by the educator and more time should be given to the students.
