Methodological recommendations for Summative Assessment on the subject of “Physics”
(natural science and -mathematics)
Grade 11
Nur-Sultan, 2020
Methodological recommendations for Summative Assessment are designed to assist teachers in planning, organizing and carrying out Summative Assessment in “Physics” for the Grade 11 learners. Methodological recommendations are aligned with the Subject Programme and Course plan. Summative Assessment in Grade 11 is conducted in Terms 1, 2, 3 and 4.
Summative Assessment Tasks for unit/cross curricular unit will allow teachers to determine the level of the learning objectives achievement planned for the term. Methodological recommendations comprise tasks, assessment criteria with descriptors and marks for conducting Summative Assessment across the unit/cross curricular unit. Also this document includes possible levels of the learners’ academic achievement (rubrics). Tasks with descriptors and marks can be considered as recommendations.
Methodological recommendations are designed for secondary school teachers, school administrations, educational departments’ seniors, regional and school coordinators in criteria-based assessment and others.
Free access to the Internet resources such as pictures, cartoons, photos, texts, video and audio materials, etc. have been used in designing these Methodological recommendations.
