One important aspect of physics instruction is helping students develop better problem solving expertise. Besides enhancing the content knowledge, problems help students develop different cognitive abilities and skills. This paper focuses on ill-structured problems. These problems are different from traditional “end of chapter” well-structured problems. They do not have one right answer and thu...

Intelligent Tutoring Systems and the evolution of Adaptive Hypermedia have opened the way for the emergence of Web-based Adaptive Educational Systems (AES). However, AES have not yet been sufficiently tested for ill-structured knowledge domains. In this paper we examine the question of applicability of AES for constructivistoriented instruction for such domains. More specifically, we identify t...

despite the extensive deployment of multi-core architectures in the past few years, the design and optimization of each single processing core is still a fresh field in computing .on the other hand, having a design procedure (used to solve the problems related to the design of a single processing core )makes it possible to apply the proposed solutions to specific-purpose processing cores .the i...

When the effectiveness of an instruction is based on outcomes students at end lessons, heterogeneity classroom could not be ignored. Considering fact that Malaysian classrooms consist mixed-ability students, Cambridge Baseline Study (CBS), which was conducted in 2013, prior to education reformation, emphasised use Differentiated Instruction (DI). Since DI relatively new system, little known phe...

The DFU is based on a commodity DRC platform DS2004, containing two AMD Opteron 2350 quad core processors and two Opteron socket compatible DRC Reconfigurable Processor Units (RPUs), all of which are connected via Hypertransport interconnects. Internal Components of the DFU: 1. HT Interface: Used to decode the HT read/write signals to internal DFU components 2. Statistics Registers: Tuples Proc...
