The PISA(Program for International Student Assessment), an international comparative study supervised by OECD, is aimed at producing reliable and internationally comparab1e indicators of students' literacy in reading, mathematics, and science. In mathematical literacy, Korean students ranked the 2nd out of the 32 participating countries in PISA. This result is very encouraging in the sense that the scores in the mathematical literacy is the forecasting indicator for the mathematical level of future citizens who are supposed to lead their countries in every fields. In contrast to the high performance in mathematics, Korean students possess extremely low level of interest in mathematics. On the other hand, Korea's highest top 5% students are not on a par with the best students in New Zealand, Japan, Swiss, Australia, and England. This finding urges Korean education to put serious efforts to pursue academic excellence. Overall, PISA results suggest that Korean mathematics education has been effective and efficient. Korean education system should set goals to meet the world standard and the challenges of the lifelong teaming society.

The purpose of this study is to check the educational influence and accountability of school library and to derive implications for the improvement of public education, using raw data of OECD PISA 2009. To do this, the reading achievement as well as questionnaire of 4,989 Korean students' data in OECD PISA 2009 were used. It analyzed how the visit of library can affect reading achievement, reading attitude and behavioral through structural equation modeling method. The results were as follows. The library use factor is a cause-effect relationship among reading achievement, reading attitude and behavioral factors. In addition, the reading attitude is a cause-effect relationship between reading behavior factor and reading achievement. In the part of reading behavior is a cause-effect relationship reading achievement. In the results of applying this causal relationship of whole population, in some individual cases, they are activated as moderating variable.

This study was conducted with the aim to develop and improve the assessment literacy of teachers which enables it to develop and utilize the assessment items using a wide range of contexts on the basis of an understanding of math contents and mathematical process specified in the math curriculum and to analyze the results in an effective way. To analyze the changes in the development and improvement of the assessment literacy of preservice math teachers, the author of this study, using PISA items and assessment framework, analyzed the changes through the 1st and 2nd development of assessment items. The results showed the assessment literacy of preservice math teachers and their ability have been improved, implying that there is the necessity to develop a wide range of programs to improve the assessment literacy of preservice math teachers and provide such programs on a regular basis, which will facilitate effective math teaching and learning.

In the 21st century knowledge and information society, students' ICT skills is a necessary tool. So, the OECD PISA survey and compares students' ICT skills across OECD countries by every three years. As a result, we are looking forward to reflecting on education. In this study, I analyzed the 2009 and 2012 PISA ICT statistics. Analysis items are as follows. Is any of these devices available for students to use at home or at school? How often do students use a computer for following activities at school? Analysis tools adopted a method to compare the ratios of the average. The results are as follows. In 2008, five items of availability of ICT at schools were evenly by five groups In 2012, all five items is very low group. Except for one of the eight items of use of ICT at school, and all items are the lowest group. In 2012, all eight items are the lowest group. Korea ICT indicators have been very down in 2012 than in 2009.

Korean students ranked the 3rd out of 32 participating countries in the first cycle of PISA(Programme for International Student Assessment) science field, which assessed 15-years-old students' scientific literacy. PISA developed several variables such as parents' socio-economic status, parents' educational attainment, family wealth, and cultural possession, to investigate the effects of background variables on scientific literacy. On the other hand, motivation and engagement in science study were not given much attention, partly because science was the minor area in the first cycle of PISA. Therefore, PISA Korea developed a series of variables to collect data on students' learning motives and out-of-school activities in science as a national option. The results are as followings. First, Korea was found to be one of the PISA participating countries with the scientific literacy achievement least influenced by parents' socio-economic status, family wealth, and parents' cultural possession. Second, the degree of achievement in scientific literacy according to parents' educational attainment was in a positive correlation, similar to the overall tendency of PISA. Third, the most crucial learning motive for Korean students was their desire to develop scientific thinking abilities or obtain science knowledge. On the other hand, choosing jobs in the field of science or parental expectation was the least important learning motive. In particular, the motive for scientific learning was found to have a positive relationship with the degree of scientific literacy achievement. Therefore, the higher the students achievement, the stronger the motive for scientific learning in order to develop their ability to think scientifically or acquire science knowledge. Fourth, Korean students were shown to participate very little in out-of-school scientific activities other than watching TV programs related to science. Whatever the activities may be, the more actively involved students are in out-of-school scientific activities, the higher their scientific literacy achievement. Fifth, Korean girls were rather passive compared to boys in all areas, including science learning motive and out-of-school scientific activities. The gender difference was especially more pronounced in out-of-school scientific activities with wider gaps in such activities as reading scientific books or articles and visiting science-related web sites.

The proximal isovelocity surface area (PISA) method is an effective way of measuring the regurgitant blood flow rate in the mitral valve. This method defines the modelling required to describe the geometry of the isotach of the PISA. In the normal PISA flow model, the flow rate is calculated assuming that the surface of the isotach is either hemispherical or non-hemispherical numerically. However, this paper evaluated the estimate flow rate using a direct surface subdivision flow model based on the height field after isotach extraction using a region-based scheme. To validate the proposed method, the various PISA flow models were compared using pusatile color Doppler images with flow rates ranging from $30\;cm^3/sec\;to\;60\;cm^3/sec$ flow rate. Whereas the hemispherical flow model had a mean value of $29\;cm^3/sec$ and underestimated the measured flow rate by 35%, the proposed model and non-hemispherical model produced a c;ame mean value of $45\;cm^3/sec$, moreover, both flow models produced a similar pulsatile flow rate.

The recent international comparative studies such as PISA(Program for International Student Assessment) and TIMSS-R(Third International Mathematics and Science Study-Repeat) provide results of relative mathematics achievement of participating countries. The purpose of this paper is to compare the mathematics results of PISA and TIMSS-R. To make PISA and TIMSS-R results comparable, they were standardized. The close investigation of these standardized results reveals that the two Asian countries(Korea and Japan) and several English speaking countries have the commonality in mathematics achievement. Thus this study looks for patterns and similarities within a group of Asian countries(Korea and Japan) and Western countries(the U.S and Australia) by in-depth analysis of PISA mathematics achievement based on item response theory. As a result, it was noted that Western countries tend to perform well on open constructed items and are likely to perform better when an item involves less formal mathematics. On the other hand, Asian countries perform well when an item involves numeric or algebraic computation related to curriculum-based content, but they are relative poor at an item calls for verbal explanations or interpretations of graphs.

This study investigated Korean fifteen-year-olds' (mis)conceptions on the greenhouse effect based on the PISA results. Based on previous studies on students' ideas about the greenhouse effect, Korean students'understanding of the natural factors and human-induced factors of the greenhouse effect were analyzed. Students' misconceptions about causes of the greenhouse effect were also examined. In addition to CO2, Students mentioned CFCs, atmospheric pollution, water vapor and methane as greenhouse gases. Many students indicated that the greenhouse effect and ozone depletion have a causal relationship. Teaching implications of the misconceptions were also discussed.
