The authors adapted an experimental design to examine effects of instruction prior to entry into a children's museum exhibit on caregiver-child interactions and children's learning. One hundred twenty-one children (mean age = 6.6 years) and their caregivers were randomly assigned to 1 of 5 conditions that varied according to what, if any, preexhibit instruction the dyads received: (a) building ...

originating from vygotsky’s sociocultural theory, dynamic assessment (da) proposes a novel approach to second language acquisition (sla) research according to which a dialectical relationship is envisaged between instruction and assessment. although da has been applied to some areas of sla, there are areas, such as interlanguage pragmatics (ilp), that have been neglected.  to address the issue,...

The current study sought to explore the impact of SFL-oriented register instruction on Iranian EFL learner’ writing performance with a central focus on their English proficiency level. As its secondary aim, the study delved deeply into the learners’ perception of the register-based instruction. To these ends, 50 intermediate and 50 advanced Iranian EFL learners were selected randomly and assign...

The author presents a simple technique for teaching the Cournot model to first-year students. The approach involves demonstrating to the students that out of all rectangles with a common perimeter, the square has the greatest area. No use is made of derivatives. The same approach can be used to understand some other market forms.

The present study aimed to examine and compare the impact of teaching economic terms through etymological elaboration with three more conventional methods of vocabulary instruction in ESP courses in Iran, that is, teaching through contextual definitions, L1 translation, and implicit instruction on the learners' general comprehension of economic texts and their understanding of author's opinion....

A huge application domain, in particular, wireless and handheld devices strongly requires flexible and powerefficient hardware with high performance. This can only be achieved with Application Specific Instruction-Set Processors (ASIPs). A key problem is to determine the instruction encoding of the processors for achieving minimum power consumption in the instruction bus and in the instruction ...

In embedded processors, instruction fetch and decode can consume more than 40% of processor power. An instruction filter cache can be placed between the CPU core and the instruction cache to service the instruction stream. Power savings in instruction fetch result from accesses to a small cache. In this paper, we introduce decode filter cache to provide decoded instruction stream. On a hit in t...

Dialogic reading is an evidence-based intervention to promote the language skills of 2and 3-year-old children. This study examined conditions under which dialogic reading could be implemented in a community setting. Three methods of instruction were compared: (a) in-person with video instruction in small groups, (b) self-instruction by video with telephone follow-up and, (c) self-instruction by...
