This study analyzed content of and recognition on occupations shown from Technology Home Economics textbooks of the high school elective subject having a higher connection with the career development capability for the occupational world as shown from a curriculum analysis. Hence, this study selected 3 kinds of high school Technology Home Economics textbooks with a higher share from 6 in the 2007 revised curriculum and analyzed a frequency by characteristic of occupational content and recognition on description of a occupation. Content analyzed by researchers was examined by 2 school teachers to ensure the validity and objectivity of research findings. Research findings show that there is a great deal of frequency difference in occupations suggested by publisher and unit in the Technology Home Economics subject. Also suggestion frequency of the occupational classification by level from Korean standard industrial classification did not correspond to an actual situation of employment. Occupation names suggested from textbooks occupied 3.3% of those by Korean Occupation Dictionary, showing a higher suggestion ratio at occupations preferred by adolescents. In the textbooks, occupations were suggested from reading materials, photos and illustrations more than from texts. Recognition on descriptions of occupations showed for the most part the neutral(82.8%) and the positive16.2%)', and there was no biased intention even from some negative cases(1.0%). Based on research findings, this research has significance in that it suggested things to be considered for teaching career development capability in the high school Technology Home Economics subject and need for cultivating teachers' specialty to understand occupations and instruct career development.

There have been many discussions about scientific literacy (SL), which caused many science educators concern for many years. This paper focuses on three aspects about SL. First, there are various opinions, and components or types of SL. Second, it has been pointed out that the reconciliation between curriculum focusing on SL and curriculum focusing on scientific knowledge system is difficult. Third, the level of SL of citizens who learned science in schools is not so high. Related to these aspects, this paper suggests three recommendations. First, the paper suggests three dimensional model of SL and some examples of its application. Second, elementary and middle school focus on SL in their science curriculum and high school focuses on scientific knowledge system in the curriculum for preparing for future jobs. Third, we need to give efforts to lifelong science eduction for citizens' SL as well as school teachings for SL. In the conclusion section, it is described what aspects should be additionally considered for the discussions and recommendations about three aspects of SL.
