Common Difficulties Students Experience With Arithmetic Operations

Reading difficulties and arithmetic difficulties

Learning difficulties in reading and arithmetic are among the most commonly noted in school-age learners, with around 5% seriously affected in each skill. Reading appears to involve a brain network that has little overlap with that for basic number processing, and the candidate genes for reading disability seem to be quite different from those for dyscalculia. Nevertheless, there is evidence th...

Arithmetic and logic operations with DNA

The use of DNA molecules to solve hard computational problems has been demonstrated in recent studies. However, the question of suitability of DNA for solving simple computer operations, such as boolean or arithmetic operations, has largely been unaddressed. Incorporation of these operations in DNA computing is essential for solving a wide range of applications. We present a xed bit encoding sc...

Upper-division students’ difficulties with Ampère’s law

This study presents and interprets some conceptual difficulties junior-level physics students experience with Ampère’s law. We present both quantitative data, based on students’ written responses to conceptual questions, and qualitative data, based on interviews of students solving Ampère’s law problems. We find that some students struggle to connect the current enclosed by an Ampèrian loop to ...

Students’ difficulties with integration in electricity

This study investigates the common difficulties that students in introductory physics experience when solving problems involving integration in the context of electricity. We conducted teaching-learning interviews with 15 students in a second-semester calculus-based introductory physics course on several problems involving integration. We found that although most of the students could recognize...
