The Present study aims at investigating the correlation between the implicit theories of intelligence ,positive thinking skills ,and mental flexibility at gifted and average students in science of second-grade secondary school students, and identifying the differences between gifted and average students in science performance in the implicit theories of intelligence ,positive thinking skills ,and mental flexibility. It investigates the predictability of positive thinking skills and mental flexibility based on the implicit theories of intelligence .
The study sample consisted of (50 students were gifted in science, and 50 were average in science) from science section at the second grade secondary school students of Sohag governorate ,in order to collect data the study applied the scale of Purdue Academic Rating Scale science (PARS), collected the participants ’scores in physics in 2020/2021, Raven’s Progressive Matrices (Emad hasan,2016), Creative thinking scale (Abraham,1977;both translated and verified psychometric by Magdy Abd Elkareem,1990), the Implicit Theories of intelligence scale (Abd-El-Fattah & Yates, 2006; both translated and verified psychometric by Abd-El-Rasoul,2017) and used both Positive Thinking scale and Mental Flexibility Scale ,(both prepared by the researcher) .
There was a statistically significant positive correlation between the scores of gifted and average students in science of second-grade secondary school students on the domain of incremental theory of intelligence and the scale of positive thinking skills at the level of (0.01). There was a statistically significant negative correlation between the scores of gifted and average students in science of second-grade secondary school students on the domain of entity theory of intelligence and the scale of positive thinking skills at the level of (0.01).
There was a statistically significant positive correlation at the level of (0.01) between the scores of gifted and average students in science of second-grade secondary school students on the domain of incremental theory of intelligence and the scale of mental flexibility . There was a statistically significant negative correlation at the level of (0.01) between the scores of gifted and average students in science of second-grade secondary school students on the domain of entity theory of intelligence and the scale of mental flexibility .
There was a statistically significant positive correlation at the level of (0.01) between the scores of gifted and average students in science on Mental Flexibility with its domains and their scores on positive thinking skills with its three domains.
There were statistically significant differences at the level of (0.01) between scores means of gifted students in science and average students at the domain of Incremental Theory of Intelligence, Positive Thinking Skills with it’s three domains (Self-Talking, Positive Imagination, Problem Solving), ,and Mental Flexibility with its domains (Adaptive Flexibility, Spontaneous Flexibility) in favor of gifted students in science .
There were statistically significant differences at the level of (0.01) between means scores of gifted in science and averages students at the domain of Entity Theory of Intelligence in favor of averages students in science .
The results of multiple regression showed that the ability of Incremental theory of Intelligence to predict the positive thinking skills of gifted students in science of second-grade secondary school.
The results of multiple regression showed that the ability of Incremental theory of Intelligence to predict Positive Imagination skill, problem Solving Skill ,and the ability of both Incremental and Entity theories of Intelligence to predict the Self-Talking skill averages in science of second-grade secondary school students.
The results of multiple regression showed that the ability of Incremental theory of Intelligence to predict the Mental Flexibility of gifted and average in science of second-grade secondary school students.
