Mathematics is not an independent science, and teaching it is strongly related to daily life. Teaching mathematics, in general, embraces teaching mathematical values that are of three types:general educational values, mathematical values, and educational values. However, more precisely, one of the approaches employed in teaching mathematics is the problem-solving approach, which instills values in the characters of students which help in shaping their personalities by granting them the chance to rely on themselves. In this way, it helps students to become independent, tohave strong personalities, and to be capable of solving problems in their lives. In addition, problem-solving teaches students to be collaborative, innovative, and socially-active. However, the problem-solving approach consists of three levels, namely tasks, cooperative groups, and sharing. In brief, the approach urges students to interact with other students in a group in order to find the proper solution for a certain task and then share the solution alongside the reasoning with the other students of the other groups. This approach encourages reasoning and creative thinking alongside with group work and self-reliance. Consequently, teaching mathematics through employing the problem-solving approach is of great importance for the individual and the community as well taking into consideration how important the values the approach instills in students. This study recommends employing this approach in teaching mathematics for students to be self-confident, critical thinkers, and problem-solvers in real and social life, which will benefit the country as a whole.

The maintenance of Late Swelling peaches quality attributes during shipping and storage was investigated. Fruits harvested at early ripe stage were either dipped in chitosan solution (Chi.1 and Chi.2) or put in modified atmosphere packages (MAP1, MAP2 and MAP3) and then held in storage room for 10 days (simulating transport or shipping conditions) or 32 day (simulating storage conditions) at 10°C ± and 85-90% RH. The treatments effect on the fruit ability for transport and storage, as well as the fruit physicochemical characters was investigated. MAP showed positive influences on the different measured parameters especially those expressing the fruit transport and storagability where lower percentages of weight loss, unmarketable fruits and off-flavor incidence were obtained, with the MAP2 type indicating better results than MAP1 and MAP3. Also, chitosan especially Chi.2 resulted in positive influences on the transport and keeping quality of the peach fruits. Also, changes in the fruit physicochemical characteristics were at minimum by the MAP and Chi. treatments during 10 days storage, especially firmness, color and acidity content.
