Portfolio contains works that a learner has selected and collected to show growth and change for a limited time period. In terms of an assessment tool, portfolio provides the results of the student with authentic, reflective, interactive and individuals features. Also portfolio provides an opportunity of improvement about curriculum and engineering program. To apply the excellency of portfolio, the principle of portfolio should be understood well and reflected the real state of engineering education. The basic concept of portfolio as a assessment tool of engineering program outcomes was introduced. The example of a portfolio has been also suggested in the form of interactive e-based model. The model has been developed that the assessment for program outcomes was rather done from a student standpoint.

The purpose of this study is to investigate the effects of portfolio system on science teaching efficacy beliefs. From Chongju National University of Education, 83 subjects were selected. All of them are college sophomores, and 5 of them are males. The portfolio system developed by the researcher had been administered during the 1st semester of 1999. Korean Science Teaching Efficacy Beliefs Instrument (K-STEBI) was administered before and after portfolio instruction. Some parts of students portfolios were analyzed qualitatively in terms of elementary science teaching confidence. After portfolio instruction, students' science teaching efficacy beliefs increased statistically meaningfully. Elementary science teaching confidence and positive attitudes toward portfolio system also showed marked increase. Portfolio system seems to be effective in fostering pre-service elementary teachers' science teaching efficacy beliefs, and be a powerful tool for teacher education.

The purpose of this study is to investigate the effects of lessons adopting portfolio assessment regarding feedback on elementary school student's scientific knowledges, inquiry abilities and their perceptions of it. For this study, two classes of 5th grade elementary school in suburb were selected. As an experimental group, one class was selected to apply the lessons adopting portfolio assessment regarding feedback, and the other class as a control group was selected to apply the lessons adopting portfolio assessment without feedback. The investigator taught and assessed both group students. The results showed a significant difference in scientific knowledge between the experimental group and the control group (p<.05). More detailed analysis of scientific knowledge found that the feedback effect was statistically positive in the memory and the understanding domain, but there was no effect in the application domain. No statistical difference was identified in inquiry abilities. The results of the questionnaire on the perceptions of portfolio assessment showed that students of the experimental group had higher positive responses on the 'perception about the effects of lesson' and on the 'perception in scientific attitudes' than the control group. However, the control group students had higher positive responses on the 'perception about self-evaluate of their own portfolio' and the 'perception about need of feedback' than the experimental group.

The purpose of the study is to investigate the applicability of portfolio assessment to ordinary elementary science classes, and the effects of a portrolio assessment on students' science achievement, inquiry ability, and science attiudes. Two schools were sampled from a metropolitan area, a city, and three schools from rural area in central Korea. Two fifth-grade classes were sampled from each school selected, and one class is assigned to experimental group and the other to control group, respectively. The total number of participants of the study are 475. Portfolio assessmest was administered to experimental group, and conventional teaching to control group for two and half month. Science achievement test, science inquiry ability test, and science attitudes test were administered as a pre- and post-test. Portfolio asseddment seems to be applecable to ordinary elementary science classroom. Statistically meaningful difference was not found in students' science achievemant by group, region, and sex. Students' inquiry ability and science attitudes showed statistically meaningful difference by region rather than group. Experimental group showed more positive scores on some sub-domains of science attitudes, such as perception on science education, and science career, interests in science activity, and criticism. In conclusion, portfolio assessment can be applicable to ordinary dldmentary science classrooms. The effects of portfolio assessment are at least the same as the traditional teaching on student science achievement, inquiry ability, and science attitudes.

The purpose of this study was to develope and implement a teaching learning process plan applied with portfolio assessment for 'housing and residential environment' section of Technology Home Economics in a middle school. The teaching learning process plan consisting of 8-session lessons had been developed and implemented according to the ADDIE model mixed with 6 portfolio-development stages. In the development stage, 19 activity materials(5 reading texts, 6 individual and 2 group activity sheets, and 3 subject activity sheets) and 27 teaching learning materials(8 sets of pictures & photos and 19 moving pictures) were developed for the 8-session lessons. The plans applied to 2 classes 74 students in the third grade of K middle school in Gyeonggi-do during May 16th-17th of June, 2011. The results from survey and portfolio showed that the 8-session lessons had overall achieved the general goal of the teaching learning process plan applied with portfolio assessment, which was to stimulate students in the class through working with portfolio elements of activity materials. The students evaluated the whole process of 8 lessons were adequate and helpful. Students also reported they highly accomplished the goal of each lesson and actively participated in the lesson. The 3 subject activity sheets as well as other materials in the portfolio were excellently done with the average of over 90% points. These results supported that a teaching learning process plan applied with portfolio assessment was a combined lesson with evaluation and also an alternative to qualitative evaluation over the whole units. This plan might apply to other parts of housing as well as various other areas.

e-Portfolio is a useful tool that enhances students' learning competency. This paper introduces 'K-folio' which is an e-Portfolio system. K-folio is currently being implemented throughout campus. K-folio is designed to apply the theoretical framework for college level e-Portfolio. We chose RAD(Rapid Application Development) as our development method which we designed to gradually improve system's capability and usability by reflecting and implementing the suggestions of students and instructors. This paper has the following contributions: first, it proposes the e-Portfolio implementation model that is more applicable to the college environment. second, the study identifies RAD as the most suitable method for e-Portfolio development. third, it mentions important technical implications regarding the development and operation for their e-Portfolio.

The purpose of this study is to explore the strategies for application of e-portfolio for improving teaching efficacy of pre-service teachers. 35 pre-service teachers wrote reflection papers and uploaded their data to their personal e-portfolio during 10 weeks. They participated in two teaching efficacy surveys which were conducted before and after using e-portfolio. Twelve participants were interviewed regarding their experience and perceptions of e-portfolio. As the result of compared-sample tests, teaching efficacy increased statistically significantly. According to the students' interview, the pros and cons of e-portfolio were identified and the strategies for application of e-portfolio were suggested for improving teaching efficacy of pre-service teachers.
