Abstract

Introduction: Most scientific concepts that belong to the field of chemistry are abstract concepts. Therefore, students need mental imagery to understand these concepts. Considering the high goals of the education system, in relation to increasing the quality of teaching and learning of students, the present research was conducted with the aim of investigating the effect of infographic-based instruction on the learning of the chemistry course of eleventh grade students.
Method: The current applied research was conducted in a quasi-experimental manner on two control and experimental groups, and in the form of a pre-test and a post-test. The statistical population of the research is all the 11th grade high school students of cities of Tehran province. The size of the statistical sample using Cochran's formula was estimated to be equal to 56 people who were selected through cluster sampling. Adobe Illustrator 2022 and Paint software were used to prepare 30 infographics. Compliance of the topics and concepts of infographics with the goals of the textbook was confirmed by four faculty members and five teachers with chemistry experience. The information gathering tool of the researcher-made test contains 20 questions in the fields of knowledge, understanding and analysis. The validity of the test questions was confirmed using the opinions of the expert group. The reliability of the test questions was obtained using the Kuderrichardson method equal to 0.73. Research data were analyzed using IBM SPSS Statistics 26 software at a significance level of P<0.05.
Results: The findings show that after the implementation of teaching using the infographic method, the average grades of the students in the experimental group have increased significantly compared to the control group. Also, the average scores in the areas of knowledge, understanding and analysis of the students of the experimental group before and after the implementation of teaching in the infographic manner have increased.
Discussion and Conclusion: The results show that teaching using infographics can increase the level of knowledge, understanding and analysis of students in chemistry.
