Based in the region of Ekurhuleni in Nigel, east of Johannesburg, CTLE employs 450 employees and is fully compliant with Black Economic Empowerment principles.
Likewise, this operation enables CTLE to benefit from Alstom s global leadership in rail transport, new technologies, as well as its world-class tools and processes.
The CTLES was then distributed among 523 (M=253 and F=270) Iranian university students in twenty-five translation classes in four universities.
In order to check the inter-correlation among the items, the correlation matrices for actual and preferred forms of the CTLES were provided.
To have parallel scales in both forms, and to keep the number of item in CTLES equal to that of CLES, all the thirty items were retained and the refined version of the CTLES consisted of five six-item scales.
1 Internal consistency reliability of the refined CTLES
Table 4 suggests that each scale of the refined CTLES has acceptable internal consistency in all cases.
2 The ability of the refined CTLES to differentiate between classrooms
This characteristic was explored for each scale of the actual form of the refined CTLES for the total sample of 523 Iranian students described previously.
Based on the analyses reported above, it is clear that the refined CTLES exhibited satisfactory factorial validity and internal consistency reliability and that the actual form of each scale was able to differentiate between classes.
Data collected using the CTLES were used in a research application involving investigation of whether there were differences between students' actual and preferred classroom environment scores on the scales of Personal Relevance, Uncertainty, Critical Voice, Shared Control and Student Negotiation.
