AU - Hegazy, Reda El-Sayed Mahmoud. AB - This study aimed at diagnosing alternative conceptions about Thermochemistry concepts among a sample of first grade secondary stage students. The study also aimed at identifying the effectiveness of reframing strategy based on Neuro Linguistic Programming (NLP) in modifying alternative conceptions about Thermochemistry concepts and developing achievement and achievement motivation among low achievers at the first grade of the secondary stage. The sample of the study included low achievers from Abdelmonem Wasel Secondary/ Prep School and Abdelwahab Motawe Secondary/ Prep School. The experimental group studied the Thermochemistry unit using reframing strategy based on NLP while the control group studied the same unit using the traditional method. The results of the study revealed that alternative conceptions in the diagnostic sample reached more than 20% where the highest was 80% and the lowest 22%, which is a high percentage showing a clear weakness in correct scientific understanding of Thermochemistry concepts among the participants. The results also showed the effectiveness of the reframing strategy based on NLP in modifying alternative conceptions in Thermochemistry, and developing achievement and achievement motivation among low achievers at the first grade of the secondary stage. The study recommended the necessity of paying attention to preparing diagnostic tests for identifying the patterns of scientific alternative conceptions among the Chemistry students at the different educational stages. It also recommended including a part on diagnosing alternative conceptions and their treatment in the teacher’s guide. Training in-service teachers on diagnosing and using the reframing strategy based on NLP in modifying alternative conceptions and helping students to acquire the correct scientific concepts should also be paid more attention.
