The reality of employing the mathematics lab and its relationship to developing geometrical proof skills among high school students

Abstract The study aimed to reveal the reality of employing the mathematics laboratory and its relation to the development of geometrical proof skills among high school students. Descriptive and semi-experimental methods were used to answer the research questions, and the study conducted a questionnaire administered to the secondary school teachers aimed at revealing the reality of employing the mathematics laboratory from their point of view and a list of geometrical proof skills necessary for high school students. A random sample was selected and represented by the research community that includes female teachers and female students in the secondary stage in Jubail city. The research sample consisted of (12 teachers and 58 students) divided into two groups, the first group included 28 students who studied geometrical proof by employing the mathematics laboratory, and the second group included 29 students who studied geometrical proof without employing the mathematics lab. The results showed that the reality of employing the mathematics laboratory from the point of view of the secondary school teachers in Jubail city was generally moderate, as there are statistically significant differences at the level of (0.01) of the means of scores between the first group and the second group in the skill of inferring relationships and the skill of the evaluation of proof due to the employment of the mathematics laboratory.
