Peer observation of teaching (POT) is a reciprocal process where a peer observes another’s teaching (classroom, virtual, on-line or even teaching resource such as unit outlines, assignments). Peers then provide constructive feedbacks that would enable teaching professional development through the mirror of critical reflection by both the observer and the observee (Brookefield, 1995). Peel (2005...

This study investigated the effect of cooperative learning on reading achievement primary school pupils in Awka Metropolis South Local Government Area. Two research questions and two null hypotheses guided study. The adopted a quasi-experimental design specifically pre-test, post-test control group design. population comprised 3,419 five metropolis 65 selected from schools that use Macmillan En...

Background: In the current COVID-19 pandemic, there is a rising need for a rapid and reliable diagnostic tool. We hypothesized that chest computed tomography (CT) can be a potential alternative for reverse transcription-polymerase chain reaction (RT-PCR). The aim of this study was to compare the diagnostic value of chest CT and RT-PCR in Iranian patients with suspected COVID-19. Methods: In a...

Temperature dependence of the Kováts retention index (I) was measured for some aliphatic ketones and aldehydes on a poly(dimethyl siloxane) (HP-1) stationary phase. An interesting minimum (non-linearity) was observed for the I versus isothermal column temperature (T) relationships. A novel empirical model is proposed: I=A+B/T+C ln T, where A, B and Care equation constants and B/C = T(min). A de...

Neurophysiological studies have demonstrated that in primates Magno and Parvo neurons have distinct contrast gain properties. Reaction Times (RTs) can be used to study supra-threshold contrast coding in humans over the same range of stimulus parameters. RTs to achromatic sinusoidal gratings were measured for a range of spatial frequencies (0.49-17.7 c/degree), stimulus luminances (0.005-20 cd/m...

PURPOSE There is great recent interest in the potential value of using pentoxifylline (3,7-dimethyl-1(5-oxyhexyl)-xanthine, PTX) as an inhibitor of radiation-induced late normal tissue damage. The effects of PTX on the radiobiological parameters (alpha/beta ratio, repair half time T(1/2)) of radiation myelopathy were studied in a rat model. MATERIALS AND METHODS Anesthetized Sprague-Dawley ra...

This study aims to improve student's reading skills in class. It was through the application of Reciprocal Teaching Strategy. Creating teaching activities Reading helps create more profound and meaningful learning. The students were very enthusiastic about understanding text because they cooperated groups summarize discuss contents text. Each group member has an equal opportunity read, summariz...
