Abstract

The approach of learning through observation provides a platform for observing appropriate behavior and performance in chemistry education for teachers. In this approach, the learner can learn by observing the behavior and performance of the teacher and his classmates and solve educational problems by doing group activities. In this research, the effect of conducting an experiment with simple devices according to the learning through observation approach on knowing the concept of ionic dissolution in tenth grade students has been investigated. The statistical population included all female students of the 10th grade of experimental and mathematical fields of Hajar school in Isfahan city, 17 of them were selected as a statistical sample using available sampling method. The research was conducted by examining experimental and control groups. The research data collection tool is a diagnostic test containing two questions including one descriptive question and one four-choice question. The descriptive question of the test is related to the completion of the dissolution reaction of ionic compounds and its four-choice question is related to the ions formed after the dissolution of ionic compounds. The results of the research show that education based on the approach of learning through observation has a positive effect on learning the concept of ionic dissolution and students who have learned this concept based on the approach of learning through observation, can answer the questions of this topic correctly.
