The study aimed to investigate the effectiveness of teaching using the
Problem-Solving-Based model on the algebraic thinking and the attitude
towards mathematics among eighth-grade female students. The study used a
quasi-experimental approach and had a total of 69 participants from the
Governorate of Muscat in the Sultanate of Oman, divided into an experimental
group 34 students and a control group 35 students. The study constructed
teaching materials based on the problem-solving- based model and used two
reliable tools to gather data: The Algebraic Thinking test made up of 14 items
and the Attitude Towards Mathematics Scale consisting of 24 items. The
results of the data analysis related to the effectiveness of the teaching program
showed that there were statistically significant differences at the significance
level (α ≤ 0.05). The mean scores of the experimental group were higher than
the mean scores of the control group regarding the total algebraic thinking test
and all its related skills and the total mean scores of the attitudes towards
mathematics scale and two of its dimensions, particularly: realizing the value
of learning mathematics and enjoying learning mathematics. Considering the
previous findings, the research proposes several recommendations. The
foremost recommendation is to utilize the teaching guide that was developed
by the researcher in this study. Additionally, teachers should be introduced to
algebraic thinking skills and techniques to advance them. It is also crucial to
consider students' attitudes towards mathematics, as it positively impacts
academic achievement and enhances their motivation to learn. The study
suggests conducting further research to explore the efficacy of problem-based
teaching models on various research variables.
