The Impact of Three Feedback Types on Postgraduate TEFL Student Teachers’ Writing Accuracy and Organization
One skill that student teachers need to develop during their academic studies is the capacity to produce accurate and well-organized texts. This study reports on the comparative impact of metalinguistic feedback (MLF), teacher interactive feedback (TIF(, and the peer-feedback (PF) on the accuracy and organization of postgraduate ELT student teachers’ writing. The participants were 57 postgradua...
متن کاملUnderstanding stream geomorphic state in relation to ecological integrity: evidence using habitat assessments and macroinvertebrates.
Scientists have long assumed that the physical structure and condition of stream and river channels have pervasive effects on biological communities and processes, but specific tests are few. To investigate the influence of the stream-reach geomorphic state on in-stream habitat and aquatic macroinvertebrate communities, we compared measures of habitat conditions and macroinvertebrate community ...

Introduction Conclusions References Tables Figures ◭ ◮ ◭ ◮ Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures ◭ ◮ ◭ ◮ Back Close Full Screen / Esc Abstract Spatial variation in hydraulic conditions in streams often results in distinct water surface patterns, or surface flow types. Visual assessments of the distribution of surface flow types have been used t...
متن کاملA Review on Macroinvertebrates’ Physiological Response to Regulated Stream Flow
Short rainfall, elevated rates of evaporation, exhaustion of underground water levels and highly inconsistent stream flow regimes have encouraged the construction of big dams and other water regulating infrastructure development resulting in degradation of river ecosystems. These major changes transform and reduce the biological composition of rivers, isolating populations of aquatic life and t...
