The first part of the graduation thesis comprises collected and reviewed literature about differentiation and individualisation in the classroom. The terms differentiation and individualisation are explained and their role in the Chemistry Curriculum for primary schools is elaborated. Furthermore, basic guidelines, instructions and concepts, concerning differentiation and individualisation in Slovene schools, which were confirmed by the Council of Experts of the Republic of Slovenia for General Education, are presented. In the theoretical part of the graduation thesis, the role and the meaning of experimental work in Chemistry classrooms are elaborated, based on the Chemistry Curriculum for primary schools. Also, the various forms of experimental work are described and guidelines for the development of teaching materials for the experimental work monitoring are given.
The second part of the graduation thesis presents possibilities for differentiation of the students’ experimental work, elaborated on one example of chemistry lecture for primary level chemistry (grades 8 and 9). For this purpose, an example of chemistry lecture based on students` experimental work is developed in three-fold level: (1) students` with learning difficulties, (2) average students and (3) gifted students. Differentiation of students` chemical experimental work is based on: different number of anticipated experiments, different complexity of the tasks on the worksheet and various extend of guiding pupils when carrying out the experimental work. In support to all three differentiated versions of students` experimental work the following teaching materials have been developed: teacher’s instructions for simultaneous implementation of differentiated students` experimental work, three versions of worksheets for students based on three differentiated implementations of experimental work.
