Development of the content and interface of the software simulator for the course “Inorganic Chemistry” and study of its effectiveness

Abstract

The purpose of our research is to develop and study the effectiveness of an interactive system of programmed teaching in inorganic chemistry in secondary schools, based on personal computers with Windows and Android smartphones. To achieve the goal of the experiment, based on the material of the book by Nentwig I. “Chemical Simulator”, we developed the course content for programmed chemistry teaching in secondary school. The content of the textbook generally corresponds to the modern school curriculum. The analysis of the task structure allows us to establish that the Nentwig approach combines linear and branched algorithms. This makes it possible to achieve adaptability of the material and obtain individual trajectories for each of the students. Based on this material, an application interface has been developed that automates the study of the material of the book “Chemical Simulator”. A database with tasks has been created. An open free SQLite3 format was used to create the database. Data entry into the database was carried out by copying the recognized scanned text of the textbook into a special form of the developed application. A workable test version of the application that implements the intended functionality has been developed. The application passed the test at school. The results of the analysis of application logs and questionnaires of participants showed that the developed complex can be used in the study of chemistry at school. Based on the results of the experiment, it can be concluded that programmed learning in the study of individual topics of the basic course of inorganic chemistry will increase the success of the assimilation of educational material by students.
