Background: In Mathematics Education, the theoretical reference of Advanced Mathematical Thinking has contributed to some research. However, others opt for a different but somehow related reference. Identifying similarities and differences between those references can elucidate researcher’s motivations when adopting one or another Objective: synthesise three studies involving Creativity, Advanc...

Many tutors offer students reference material or tips that they can access as needed. We have logged data about student use of references with Deep Thought logic tutor which to understand why and how references are used. We find evidence that students use these references in systematic ways that change over the course of the tutor, and can be predictive of rule application errors. We can use th...

The power of objects lies in the flexibility of their interconnection structure. But this flexibility comes at a cost. Because an object can be modified via any alias, object-oriented programs are hard to understand, maintain, and analyze. Aliasing makes objects depend on their environment in unpredictable ways, breaking the encapsulation necessary for reliable software components, making it di...

implantable ports are used for intravenous infusion therapy and play an important role in management of oncology patients. these ports are best suited for patients requiring long-term therapy (>4 weeks). implanted ports provide reliable venous access protect peripheral access increase patients’ comfort through reducing repeated and difficult vein punctures allow for safe and comfortable adminis...
