Recently, performance assessment that makes growing use of free response items in a large scale assessment has been emphasized. This study is an empirical examination of the effectiveness of free response items in comparison with multiple choice items. Using the information function in Item Response Theory (IRT) framework, item information of free response items and multiple-choice items from the Third International Mathematics and Science Study-Repeat (TlMSS-R) were obtained. Test information of the whole science area as well as each area of science contents was computed. On average, free response items yielded more information than multiple choice items, especially in earth science, physics, chemistry, and life science. This study also showed that free response items were appropriate for students in high science ability. Also, free response items estimated students' science ability more accurately than multiple choice items with smaller number of free response items.

This study examined the relationship between the critical thinking disposition and problem solving ability as well as the influencing factors the problem solving ability in nursing students. The data was collected from 422 nursing students of 4 colleges and analyzed using the SPSS/WIN 18.0 program. The mean score of the critical thinking disposition was $3.42{\pm}0.42$ and the problem solving ability was $3.84{\pm}0.50$. A significant positive correlation was observed between the critical thinking disposition and problem solving ability. Multiple regression analysis showed that the predictors of the problem solving ability were the critical thinking disposition and interpersonal relationship. These findings suggest that there is a need to increase the critical thinking disposition and problem solving ability in nursing students. These results should be reflected in an evaluation and development of the curriculum and learning method.

This study investigates the effect of self-esteem and Korean ability on acculturative stress of marriage-based immigrant Asian women in Korea. It also attempts to find out whether self-esteem has any mediating effect between Korean ability and acculturative stress. By using purposive sampling method, 280 samples were collected among Vietnamese, Filipino, and Chinese women in Daegu from Oct. 12th to Nov. 3rd, 2008. The results are as follows: The higher the score of self-esteem and that of Korean ability is, the lower the score of acculturative stress is respectively. It is proved that self-esteem has mediating effect between Korean ability and acculturative stress. Therefore it is emphasized that programs which can improve self-esteem should be provided to marriage-based immigrant women, especially to those who do not have sufficient Korean ability. Sending money to home country shows both direct and indirect effects and subjective economic evaluation shows direct effects on acculturative stress score. For the purpose of the study acculturative stress scale has been modified based on Sandhu and Asrabadi(1994), which turns out to be useful to measure acculturative stress of marriage-based immigrant Asian women in Korea because it reflects their life circumstances quite well. Some practical implications of social work are suggested through discussion.

This study is to apply the Havruta teaching-learning method to college students' major classes and analyze the relationship between the effectiveness evaluation of communication skills and sub-factors using a structural equation model. As a result of the study, the communication ability score was different before and after Havruta teaching-learning, and it was found that after Havruta teaching-learning was higher than before Havruta teaching-learning. The path effect was found to be significant in all of the total, direct, and indirect effects among latent variables, except for the relationship between interpretation ability, role-playing ability, and goal-setting ability in the direct effect. In this study, it was found that the Havruta teaching-learning method not only improves creativity and thinking ability, but also improves self-directed learning ability. In addition, it was reconfirmed that it is a teaching-learning method that can develop social skills and communication skills as well as problem-solving skills while experiencing opinions different from one's own. As a result, research on a thorough student-centered teaching-learning method suitable for the Homo Machina era must be continued and its application in the educational field must be implemented.

The purpose of this study was to investigate the relationship among functional evaluation systems, the Manual Ability Classification System (MACS), the Gross Motor Function Classification System (GMFCS), and the functional status (WeeFIM) in children with spastic cerebral palsy and to provide the foundation data about MACS for evaluation system of hand function in children with spastic cerebral palsy. For this, sixty children with spastic cerebral palsy were employed in this study. The sixty children were evaluated by using the MACS for their hand function and by using the GMFCS for their motor function. The functional status were assessed by using the Functional Independence Measure of Children (WeeFIM). There were a significant correlation between the MACS and the GMFCS (r =.659, p <.05). The good correlation between the MACS and WeeFIM was found (r = -.576, p <.05). The functional status according to the hand function level evaluated by using the MACS were different significantly (p <.05). The MACS in practice will provide usefulness for assessment of hand function in children with spastic cerebral palsy.
