Development of mentor teacher role inventory

This study aimed to develop and investigate the validity and reliability of the Mentor Teacher Role Inventory (MTRI). A total of 1843 student teachers in the Distance English Teacher Training Program participated in the study. The 58 items of the Mentor Teacher Role Inventory underwent principal factor analysis, which revealed nine factors relating to mentorship and explained 52.971% of the total variance. The KMO value of the MTRI was calculated as .968. The Cronbach's alpha was .951. These results indicated that a reliable and valid MTRI could be used for both the distance English teacher training programme and other distance teacher education programmes.     

Sentiment classification: a lexical similarity based approach for extracting subjectivity in documents

With the growth of social media, document sentiment classification has become an active area of research in this decade. It can be viewed as a special case of topical classification applied only to subjective portions of a document (sources of sentiment). Hence, the key task in document sentiment classification is extracting subjectivity. Existing approaches to extract subjectivity rely heavily on linguistic resources such as sentiment lexicons and complex supervised patterns based on part-of-speech (POS) information. This makes the task of subjective feature extraction complex and resource dependent. In this work, we try to minimize the dependency on linguistic resources in sentiment classification. We propose a simple and statistical methodology called review summary (RSUMM) and use it in combination with well-known feature selection methods to extract subjectivity. Our experimental results on a movie review dataset prove the effectiveness of the proposed methodology.

Effects of ‘Environmental Chemistry’ Elective Course Via Technology-Embedded Scientific Inquiry Model on Some Variables

The purpose of this study is to examine the effects of ‘environmental chemistry’ elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers’ (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test–post-test design, the study was conducted with 117 SSSTs (68 females and 49 males—aged 21–23 years) enrolled in an ‘environmental chemistry’ elective course in the spring semester of 2011–2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs’ conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the ‘environmental chemistry’ elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.
