摘要：In this paper, we propose an approach to development of student accountability for study of a subject in a PBL environment through its specific organization by a teacher. It allows to include process of developing accountability of students for PBL to accountability area of a teacher. Accountability of the students for PBL is developed by a seven-step process for the specific organization of the PBL environment. The steps are preparing the sample-project, setting initial knowledge assessments, ensuring study of a subject by a class through performance of the sample-project, promoting self-formation of collaborative student groups for performing projects of different levels of complexity, adapting PBL to knowledge dynamics of students by setting the adaptive assessments of knowledge, sustaining collaborative performance of the project tasks, and measuring student accountability. The stages of development of student accountability for PBL conformed to the steps of organizing the PBL environment are determined. The stages are engendering concern about the need to take accountability for studying the subject matter in the PBL environment, motivating students to take accountability for acquiring the subject-relevant knowledge while performance of the sample-project, the habituation of students to take accountability for study of a subject through performing a sample-project, inducing and guiding of students to take accountability for collaborative performance of projects of different levels of complexity, stimulating students to hold accountability for collaborative performance of the projects, reinforcing student accountability for collaborative performance of the project tasks, and evaluating development of student accountability and a level of accountability skills.
