a tale of three official english textbooks: an evaluation of their horizontal and vertical alignments

Instructional materials as a basic component of curriculums and a central constituent of standardsbased programs play a provisional role in both setting the aims and leading the way. english textbooks in iran’s public education are officially developed and used nationwide. one recently introduced english textbook series is prospects (iiii) . it is intended for the the iranian junior high schools and is normally supposed to guide teachers and provide students with the basic exposure to english as a foreign language (efl) context. the textbooks, together with the lessons, have to be aligned in targeting educational objectives given the sequential nature of the intended grades and the serial contents of instruction. this study evaluated the vertical and horizontal alignment among the series’ textbooks and lessons drawing on bloom’s revised taxonomy of educational objectives (anderson krathwohl, 2001). the evaluation initially involved descriptive content analysis of the activities within and across the textbooks using a checklist developed based on the taxonomy. then, the content matrixes were subjected to porter et al.’s (2007) alignment index for the statistical assessment of lessons and textbooks’ alignment. the findings generally suggested that the lessons were tuned adequately, albeit accommodating mainly lowerorder knowledge types and cognitive skills at the cost of discarding the higherorder ones. in addition, the statistically positive and significant pais of 0.93, 0.78, and 0.74 between prospect i ii, prospect i iii, and prospect ii iii, respectively pointed to a harmony in the series’ content. the paper discusses the findings and implications in the iranian efl context

A Tale of Three Official English Textbooks: An Evaluation of Their Horizontal and Vertical Alignments

Instructional materials as a basic component of curriculums and a central constituent of standardsbased programs play a provisional role in both setting the aims and leading the way. English textbooks in Iran’s public education are officially developed and used nationwide. One recently introduced English textbook series is Prospects (IIII) . It is intended for the the Iranian junior high schools and is normally supposed to guide teachers and provide students with the basic exposure to English as a Foreign Language (EFL) context. The textbooks, together with the lessons, have to be aligned in targeting educational objectives given the sequential nature of the intended grades and the serial contents of instruction. This study evaluated the vertical and horizontal alignment among the series’ textbooks and lessons drawing on Bloom’s revised taxonomy of educational objectives (Anderson Krathwohl, 2001). The evaluation initially involved descriptive content analysis of the activities within and across the textbooks using a checklist developed based on the taxonomy. Then, the content matrixes were subjected to Porter et al.’s (2007) alignment index for the statistical assessment of lessons and textbooks’ alignment. The findings generally suggested that the lessons were tuned adequately, albeit accommodating mainly lowerorder knowledge types and cognitive skills at the cost of discarding the higherorder ones. In addition, the statistically positive and significant PAIs of 0.93, 0.78, and 0.74 between Prospect I II, Prospect I III, and Prospect II III, respectively pointed to a harmony in the series’ content. The paper discusses the findings and implications in the Iranian EFL context
