Abstract
The aim of the research is to develop an online environment where teachers can access test and item statistics and a comprehensible report regarding the tests they have used, to ensure the storage of their reports in their own online environment as well as to have an idea on the utility of the subject matter environment. The research is planned as a design and development research. Research data was collected in two stages. The data which was needed to compare were obtained simulatively through the TAP program. Also, dta was collected from a group of 15 teachers to collect evidence for the usability of the application. Test and item statistics were calculated for the collected data and compared with the results of the programs making similar calculations. Descriptive analysis was used in the interpretation of the usability questionnaire and of teacher opinions. As a result of the research, the item and test statistics calculated for all data sets created by sampling different situations were found to be similar to those of reliable equivalent package programs. With the opinions received from the teachers, it has been concluded that the environment is useful and practical. While one of the important differences of the online environment formed by this study is its keeping a record of the past; another is its accessibility through the internet without the need for an additional program and thirdly, its usability on a mobile platform.
