Investigating problem solving and mathematical connections in solving the fermi-dirac equation

This study aimed to describe the problem-solving abilities and mathematical connections of the sixth-semester students of Physics Tadris in the Statistical Physics course, especially the BoseEinstein Equation Material. This type of research is quantitativedescriptive research. Data collection in this study used a cognitive test technique in the form of a description test to measure students'mathematical abilities, which amounted to 8 questions, of which four were used to measure problem-solving abilities, and four were used to measure students' mathematical connections. Data analysis was carried out descriptively to determine the profile of students'mathematical abilities and the distribution of predicate achievement on the ability of problem fractions and students' mathematical connections. The results showed that students' average problemsolving abilityand mathematical connection were in the Pretty Goodcategory.
