  • The purpose of this study was to provide analytic rubrics for measuring teamwork(PO6), communication and presentation skills(PO7), and life-long learning(PO8) based on theoretical concepts of performance assessment and rubrics. Also, this study analyzed data about performance assessment and rubics from courses offered through college of engineering. Participants were 34 senior engineering students who took the course 'Technical writing and presentation'. In the second week of the course, students were given the pre-test instrument which was developed for measuring students' understanding of program outcomes for this study. After performing project activities using rubrics, students were encouraged to complete the post-test instrument and the reaction questionnaire during the ninth week. The data were analyzed by using SPSS 14.0 and Microsoft Excel. The research findings are as follows. First, to promote and evaluate program learning outcomes appropriately, performance assessment-based on rubircs should be implemented. Second, in the reaction questionnaire about the rubircs, students answered that using rubircs for performing the project was very useful for understanding the performance procedures and assessment criteria. Third, the mean of understanding of program outcomes of students in post-test was significantly increased than in the pre-test(p<.0001). From the findings, performance assessment and rubrics should be used as evaluation tools at course levels in terms of promoting program learning outcomes for engineering education.

  • Audiometric calibration is a prerequisite for securing the reliability of audiometric test results by checking the internal consistency of the relevant instrument. The purpose of this review is to help instrument operators understand the calibration procedure of aural acoustic immittance instrument which is frequently used for objective assessment. By referring to the latest international standards and the national standards relevant to the aural acoustic immittance instrument, the following parameters will be reviewed: 1) introduction of performance characteristics, 2) detailed procedure of the calibration method. According to the newest international and national standards [IEC 60645-5 (2004), ANSI S3.39-1987 (R2012)], the aural acoustic immittance instrument basically includes six components: 1) calibration cavity, 2) acoustic immittance analysis system, 3) probe assembly/unit and signal, 4) pneumatic air-pressure pump system, 5) acoustic reflex activator system and 6) tympanogram and acoustic reflex plotting system, each of these components should meet set standards. The result of behavioral hearing tests is influenced by various complex factors including the examinee's cooperation, background noise of the examination room, measurement method, skill level of the audiologist and calibration status, but the objective hearing tests is more influenced by the calibration status of the instrument than any other factors. The audiologist should take full responsibility for the reliability of the hearing test result, so he/she should carry out the calibration check and adjustments of aural acoustic immittance instrument periodically and maintain the instrument continuously by referring to the newest standards and the manufacturer's instruction manual.

  • KARI is currently developing a geostationary ocean color imager (GOCI) for COMS. We report the progress in integrated optical modeling and analysis for stray light suppression and the end-to-end instrument performance verification including in-orbit calibration. The Sun is modeled as the emitting light source and the selected area around Korean peninsular as the observation target that scatters the sun light towards GOCI in orbit. The optical ray tracing employing active geometric scaling was then used for precise characterization of the spatial and radiometric performance at the instrument focal plane. The analysis results show positive reduction in the simulated stray light level with the design improvement including baffles. It also indicates that the ray traced in-orbit radiometric performances are effective tools for the independent assessment of more traditional linear and quadratic equation based estimation of water leaving radiance. The concept of integrated GOCI optical model and the computational method are presented.

  • Purpose: To evaluate the effects of case management using Resident Assessment Instrument-Home Care(RAI-HC) in home health service for older people. Methods: All elders were assessed at baseline and 3 months later using RAI-HC. The change of function in the intervention group was compared with that of a conventional intervention group. Function was measured with Activities of Daily Living(ADL), Instrumental Activities of Daily Living(IADL), Cognitive Performance Scale(CPS), Depression Rating Scale(DRS), Pain and the number of Clinical Assessment Protocols(CAP). Results: Among ninety two elders participated in the program, 59 were allocated to the case management group and 33 to the conventional group. The intervention, home health service by a nurse over a 3 month period, consisted of comprehensive assessment, case conference for care plan, direct care, education and referral, and outcome evaluation. The percent of elders whose function improved in the intervention group was greater than the conventional group for depression(odds ratio [OR]: 10.941, confidence interval [CI]: 2.338-51.206), IADL(OR: 4.423, CI: 1.151-16.999) and the number of CAP(OR: 11.443, CI: 3.805-34.410). Conclusion: Case management was effective for older people in the community. The effect might have resulted from individual, systematic intervention, however, standards of service including eligibility criteria for case management and collaboration of multi-disciplines is required for more effective home health service programs.

  • The Purpose of this study is to find the effects of the portfolio assessment on elementary students' scientific knowledge, inquiry process skill, scientific attitudes in the teaching of science. And finally the parents' response to the portfolio assessment is also investigated. In order to reach the goal of this study, the investigator developed the evaluation instrument such as an experimental report and a cumulative observation sheet for the 4th-grade Unit-1 'Light Propagation' and Unit-3 'Separating Mixtures', and then these were administered to 42 4th-grade elementary students in Inchon. Based upon the findings and within the limitations of this study, several conclusions can be drawn regarding the problems investigated. First, as the portfolio assessment offers enough information about individual student's performance, it has a highly positive effect on evaluating the students' scientific knowledges. It can also make possible to grasp the several aspects of the student's progress. Second, the portfolio assessment can be implemented without giving students any psychological pressure from testing itself. Therefore, the portfolio assessment is an effective means of appraising inquiry process skills. Third, the portfolio assessment is effective to evaluate the students' attitude toward science by means of individual records which include such aspects that is hardly found by the teacher who teaches science in the class. Fourth, as most parents showed a positive response to this portfolio assessment, it is considered to be effective method of appraising the result of teaching science at elementary school. Accordingly, this study demonstrated that the portfolio assessment is an effective method that can assess students' scientific knowledges, inquiry process skills, and scientific attitudes gained from science teaching-learning. Therefore, it is necessary to implement the portfolio assessment to other grade students as well in the following study where teacher may give more encouragements and suggestions to sti dents for the better learning motives. Also teachers should suggest more definite evaluation criteria to students so that they may improve the students' self and peer evaluation skills.
