EVALUATING ORAL PROFICIENCY SKILL THROUGH ANALYTICS AND HOLISTIC WAYS OF SCORING

Purpose: Evaluating speaking skill is an exceedingly difficult and intricate subject. Two methods of testing oral proficiency are usually used: holistic and analytic scoring. To this end, this study aimed to compare analytic and holistic techniques for scoring in evaluating oral proficiency skills. Methodology: The participants of this study were 70 second-grade university EFL students who were studying English Language Teaching at a university in Iran. The participants in this research were both male (n=40) and female (n=30) with the age range from24 to 25. Main Findings: The results showed a statistically considerable diversity between analytic and holistic methods of evaluation considering that the p-value was estimated at 0.002 (P < 0.05). Applications: The findings confirmed that employing these two scoring techniques in the procedure of evaluation may be considered proper as they seem to complement each other, one augments the other and lead to more inclusive evaluation. Novelty/Originality: This study is new since it is the first time in an Iranian university context; oral proficiency skill was evaluated through holistic and analytic scoring

The Impact of Code-switching on Vocabulary Learning among Iranian Upperintermediate EFL Learners

This study aimed to investigate the impact of code switching on Iranian upperintermediate EFL learners' vocabulary learning. To this end, 64 participants out of 90 male students were selected and randomly divided into two equal experimental groups- experimental and control groups. Then, the groups were pretested by a vocabulary pre-test. Then after, the participants of experimental group received the treatment, i.e., using code switching. After the treatment ended, both groups took the post-test of vocabulary. The results of paired and independent samples t-tests revealed that the experimental group outperformed the control group on the post-test. The results showed that there was a significant difference between the performance of the experimental and the control group on the post-test

The Monte Carlo Assessment of Photon Organ Doses from 222Rn Progeny in Adult ORNL Phantom

Introduction The potential hazards posed by exposure to radiation from radon have been of great concern worldwide, since it is especially associated with increased risk of lung cancer. Some radioisotopes of radon progeny deposited in the human lungs emit β particles followed by the γ rays. While γ rays are comparatively less damaging to the respiratory system than α and β particles, it is the principal deposited energy in other organs. Materials and Methods In order to establish a quantitative estimate of hazards caused by the radiation, this paper studies the photon absorbed doses from radon progeny in all major organs of the human body through a simulation of the Oak Ridge National Laboratory (ORNL) adult phantom using MCNPX2.4.0 Monte Carlo code and calculations which were performed in photon/electron mode. Results Effective dose due to photons from radon progeny deposited in the human lungs was about 1.69 µSvWLM-1. Based on UNSCEAR2006 reports, the effective dose of these photons per year is about 5.76´10-1mSv  in for radon concentration of 31000 Bq/m3  (the maximum concentration of radon in Iran). Therefore, this value is comparable with 1mSv (The annual allowable effective dose). Conclusion The dosimetry of photons particularly in areas with high levels of exposure to radon and radon's decay products is important because all organs receive the photon absorbed dose from radon progeny
