The Role of Concrete Manipulative Materials in Improving Achievement Level of Visually Handicapped Pupils in Mathematics: Unterschied zwischen den Versionen

# Developing the concrete and manipulative materials (modified algebra tiles) to teach the unit of algebraic terms and expressions to the visually handicapped students.

# Reshaping the content of the unit of algebraic terms and expressions in a way that suits/fits the nature of the visual handicap.

# Preparing a teacher’s guide for the unit of algebraic terms and expressions including some signs and principles that would help the teacher in teaching the unit to the visually handicapped students.   

# Preparing an achievement test on the unit of algebraic terms and expressions

# Subjecting the unit, the teacher’s guide, and the achievement test to the judgment of the experts and the educationalists to judge their suitability to the nature of the visual handicap and making the suitable modifications in the light of their suggestions.

# Reprinting the unit and the achievement test in Braille language to be easily administrated to on the visually handicapped  students.   

# Implementing a preliminary experiment for the achievement test that aims at analysing its items, measuring its factor of constancy, and determining the time of the test.   

# Implementing a pre-achievement test on both groups i.e. the experimental and the control groups.

# Teaching the unit of algebraic terms and expressions using concrete manipulative materials (modified algebra tiles) for the visually handicapped students of the experimental group.

# Implementing a post-achievement test on both groups i.e. the experimental and control groups.   

# Collecting data, statistically manipulating and explaining it, and answering the questions of the study.
