The goal of this study is to assess the effects of Scratch programming classes on preservice teachers by using computational thinking and cognitive evaluations based on Bloom's taxonomy. To pursue this research goal we measured preservice teachers' programming skills using cognitive evaluation items based on Bloom's taxonomy after preservice teachers took one-semester Scratch programming course. In addition, a survey focused on computational thinking (CT) concepts, CT practices, and CT perspectives was conducted. We also conducted artifact-based interviews to unpack preservice teachers' experiences of working on team projects and analyzed their experiences qualitatively. The results of this study are meaningful because we assessed preservice teachers' experiences comprehensively with both quantitative and qualitative methods. In addition, this study provides us with implications for evaluation perspectives in designing programming courses for preservice teachers by adopting Bloom's taxonomy scheme.

The whole world is making a variety of efforts to cope with the revolutionary changes in the economy and society that are emerging from intelligent information technology. Therefore, this study defined national public officials' intelligence information competency in the intelligent information society, and tried to derive competency clusters and sub-elements. To achieve this objective, this study explores literature research about bloom's digital taxonomy, information competency, and national ICT policies and national public officials' intelligence information competency was defined based on bloom's digital taxonomy perspective was modified and supplemented with this study and provisional constituent elements of competency were derived. In addition, 5 experts verified the content validity. As a result, 7 competency clusters and 22 sub-elements are finally derived. The findings of this study are expected to be useful as the basis for the national intelligence information human resource development.
