Abstract-In the last few decades word association research has provided precise insight into the development and organization of the mental lexicon; however, there is still sufficient ground for more exploration to gain a better understanding of how L2 learners' mental lexicon might be organized and how word association behavior may vary according to L2 proficiency level. This paper was intended to investigate the development of mental lexicon through a psycholinguistic experiment and more specifically, to explore Index Terms-mental lexicon, language proficiency, word association behavior, syntagmatic relation, paradigmatic relation
Professional development in sustainable teacher education has recently shifted to focusing on pedagogical practice rather than theoretical knowledge. Given that, reflection practice can have an effective role in identifying undiscovered potentials of prospective language teachers. Hence, the current study was an attempt to examine the potential core qualities of Iranian prospective language teachers in a way to sustain professional development through merging theoretical knowledge and pedagogical practice. To that end, core reflection model, which is a concept in the context of sustainability, was practiced by ten prospective language teachers through drawing on their reflective journals, focus group discussions, and field notes collected over a four month period. Analysis of the obtained data revealed several core qualities on the three scales of feeling, thinking, and wanting. These qualities appeared to have been developed through interaction of both theoretical knowledge and pedagogical practice. This demonstrates the value of reflection practice as a way toward more development in making sense of teachers’ core qualities. Thus it can lead to positive changes in shaping teachers sustainable professional identity.
This research is an attempt to find out if grouping learners, through using a placement test will significantly help students become more successful in learning English. 320 non-English major undergraduates studying at the University of Isfahan participated in this research. The final scores of 121 freshmen who attended their general English courses in homogenised classes were compared with those of 199 freshmen who did not undergo any placement procedure. The analysis of data suggested that grouping the learners and dividing them into different ability groups had a significant impact on the participants' academic success, in their course of general English. In addition, the results suggested that ability grouping provides sufficient ground for methodological decisions and hence sequencing of teaching materials and procedures
