This study was performed to analyze the secondary students' perceptions and self-efficacy of performance assessments in the science subject. The data was obtained from 236 middle school students and 222 high school students in seoul. The students had generally proper understanding about characteristics of performance assessment which include purposes of assessment and differences from other conventional achievement assessments. They responded that the performance assessments were not useful in their science learning and developing their potential abilities. They were not satisfied with reliability and validity of the performance assessments. The middle school students more positively responded than high school students regarding the reliability of the scoring system and the originality of the evaluating materials. The female students more positively thought than males about the reliability of assessment and the usefulness for learning science. The students' self-efficacy level of performance assessment were not low in comparison with another existing assessments. They had high level of self-efficacy in understanding of experimental procedures, and utilizing of experimental apparatuses, but had low level of self-efficacy in understanding purposes of experiments or issues of discussions, processing of experimental results, answering of problems in experimental discussions. The female students' self-efficacy of performance assessment were higher than male students'. There was statistically correlated with females' scores and their level of self-efficacy of performance assessment.

The aim of this study was to examine the effects of remedial instruction on self-efficacy improvement in elementary school students with low self-efficacy, which may have been formed through negative experience with learning such as poor performance and poor grades. Nine 6th grade students with low self-efficacy were selected for the present study. A remedial class was set up and instruction was given once a week for 14 weeks. The purpose of the remedial class was to give the students a positive experience with English learning and have students reflect on their achievement. The contents and class activities were adjusted to the subjects' English abilities and also closely related to those of the regular classes so that students could have more confidence during regular English classes. The data were collected from a test of self-efficacy in English learning, achievement tests given before and after the experiment, achievement tests after each lesson, a general self-efficacy test, a basic questionnaire, interviews, journals, and students' self-evaluation. The results showed that the remedial instruction was very successful in providing students with a sense of achievement and improving students' self-efficacy in English learning. However, this study failed to find significant improvement in general self-efficacy tests and achievement tests given before and after the experiments. A longer period of remedial instruction may have been necessary to obtain more concrete results from the variety of data collected.

Recently, self-efficacy is one of the critical constructs that have been found to influence human decisions about behavior selection and the performance associated with the selected behavior. The construct has been widely adaopted and tested in the fields of social psychology and/or other behavioral sciences. In information system field, however, it has been hardly studied, although computer self-efficiency could have been an important factor explaining and predicting human computer usage behaviors. From this perspective, main proposes of the study are : (1) to develop a measure of computer self-efficacy, 2) to identify the factors influencing self-efficacy, and 3) to reveal the relationship between self-efficacy and computer usage behavior. By reviewing the literature, past experience, others'use, encouragement by others, and anxiety are selected as the factors influencing computer self-efficacy. Four hypotheses concerning the relationship between each of the variables and computer self-efficacy are tested by LISREL. One more hypothesis about the relationship between computer self-efficacy and computer usage is also tested. The results show that computer self-efficacy is significantly influenced by computer ansiety, encouragement by others, and computer experience, and that it is closely correlated with computer usage behavior.

Purpose: In this study, effects of positive, negative, and mixed verbal feedback were examined for accuracy of self-assessment, emotional responses, self-efficacy, and perceived quality of feedback in skill performance assessment. Methods: Participants were a convenience sample of 104 second-year nursing students who had completed their fundamentals of nursing class. Participants were assigned randomly to a positive, a negative or a mixed feedback group. All participants completed the performance measure and then received the assigned the type of feedback from an evaluator. After delivery of feedback, they assessed their own performance using the same sheet as the evaluator and completed the survey for emotional response, self-efficacy for learning, and quality of feedback. Results: There were no significant differences in accuracy of self-assessment and perceived quality of feedback among the three groups ($x^2=4.74$, p=.094; $x^2=3.30$, p=.192, respectively). The negative feedback group had significantly lower self-efficacy and positive emotions and more negative emotions than the other two groups (F=9.43, p=.009; $x^2=16.29$, p<.001; $x^2=5.69$, p=.005, respectively). Conclusion: Negative feedback can affect emotions and motivations for learning in nursing students and may interfere with the effectiveness of feedback, so instructors should pay more attention when providing negative feedback. Mixed feedback with an effect similar to positive feedback could be an alternative.

This study was a quasi-experimental study to confirm the effects of a memory training program using efficacy sources. The purpose was to develop an effective memory training program for elderly people and to identify the effects of the memory training program. This study was carried out between February 24 and July 18, 1999 and the subjects of the study were 102 elderly people who were participants at a welfare institute in Seoul. The experimental group (51) and the control group (51) were assigned by means of participation order. The control group was matched to the experimental group and was selected considering age, sex, and religion. The experimental group participated in the memory training program. The memory training program was based on the literature of Fogler & Stern (1994), Wang & Lee (1990), Lee (1991) and Lee (1993). The memory training program was given twice a week for two weeks with each program lasting two hours. Task centered memory self-efficacy was measured using the Memory Self-Efficacy Scale developed by Berry & Dennehey (1989) and Meta Memory was measured by the MIA developed by Dixon et al. (1988) Memory performance was measured by the word list developed by Cho Sung Won (1995) and the face recognition task (Face Recognition Task developed for this study). Data were analyzed by SPSS PC and the results are described below. 1. The experimental group which participated in the Memory Training Program showed higher task centered memory self-efficacy scores as compared to the control group (t=4.354, P=.0001). 2. The experimental group which participated in the Memory Training Program showed higher metamemory scores as compared to the control group (t=4.733, P=.0001). 3. The experimental group which participated in the Memory Training Program showed higher memory performance scores as compared to the control group (t=7.500, P=.0001). The memory performance involved an immediate word recall task, a delayed word recall task, a word recognition task, and the face recognition task. 4. In the experimental group, there was significant correlation between the task centered memory self-efficacy scores and the metamemory scores (r=.382, P=.006), but the correlation between the task centered memory self-efficacy scores and the memory performance scores and between the metamemory scores and the memory performance scores were not significant. The results showed that task centered memory self-efficacy, meta memory and memory performance improved following the Memory Training Program including the memory process, changes in memory with aging, and appropriate use of memory strategies. Memory Training Program is an effective nursing intervention for improving memory in elderly people and, also, in people with complaints of memory loss.
