  • It is important to explore ways that reinforce teachers' curricular expertise at the school level as the school curriculum autonomy expands. This study investigated teachers' curricular expertise that is required for teachers' professionalism, autonomy, and accountability to cope with the increasing school curriculum autonomy. Teachers in the future school are expected to explore and develop school level curriculum within a given school context. Through literature reviews, domestic and foreign case studies, and survey of teachers, this study examined difficulties in science teachers' exercise of their professionalism on curriculum organization and implementation at the school level. Difficulties in exercising teachers' curricular expertise include lack of actual autonomy in curriculum operation at the school level, inadequate infrastructures, demanding accountability based on students' achievement results, lack of time for reflection, and lack of recognition for teachers as independent curriculum designers. In the conclusion section, a couple of ways to solve these difficulties are suggested including expansion of actual autonomy, activation of teachers' participation in policy decision making, reinforcement of qualitative components in school assessment, diversification of the teacher's career ladder, and activation of teachers' participation in professional learning communities.

  • The Construction industry has been dealing with much trouble due to global economic recession and domestic political trends emphasizing on welfare than development. Consequently, domestic construction market has been dramatically shrunk during the last a few years, and international market has become the only potential solution for the industry. However, there has been lack of efforts in developing a quantified measure of global competencies for Korean engineering and construction organizations. This study attempted to develop quantified indices for Korean engineering and construction contractors with which the level of global construction competencies can be objectively monitored. In doing so, a survey questionnaire was developed to identify relative importances of core competency elements which were derived from extensive literature reviews and experts interviews. AHP (Analytic Hierarchy Process) was employed as a main analysis method in developing quantification measures. The analysis results reveal little differences in competency requirements between engineering and construction firms and it implies that the global market becomes more integrated and requires a total solution for a construction project. The developed core competency measures can be used to quantify the level of preparedness of Korean engineering and construction firms at the time of evaluation and also be used as a basis for performance benchmarking indicators if they are compared with business showings.
