This study investigated the effects of varying visuals in drawing and writing as methods to assist students in connecting and integrating multiple external representations provided in learning the particulate nature of matter. Seventh graders (N=233) at a coed middle school were assigned to control, static drawing (SO), dynamic drawing (DD), static writing (SW), and dynamic writing (DW) groups. The students were taught about "Boyle's Law" and "Charles's Law" for two class periods. Two-way ANCOVA results revealed that the scores of a conception test for the two drawing (SD, DD) groups and the two writing (SW, DW) groups were significantly higher than those for the control group. Within the writing groups, students of lower spatial visualization ability in the DW group scored significantly higher than those in the SW group. However, no significant differences were found in the scores of the conception test for the two drawing (SD, DD) groups regardless of students' visualization ability. Researchers also found that most students in both DD and DW groups had respectively positive perceptions of dynamic visuals in drawing or writing.

An increasing number of educators emphasize the affective domain in learning. Affective and cognitive objectives interact and can not be separated from each other. Good emotions and feelings assist students achieving optimally in the cognitive domain. Emotional intelligence harmonizes well with an affective science curriculum. The purpose of this study was to explore the effectiveness of EQ(Emotional quotient) improvement program on students' EQ, science achievement, the science related attitudes, and science anxiety. A pretest-posttest control group design was employed. Subjects were 168 male and female first grade students in a middle school. A control group was instructed with a traditional teaching method, and an experimental group was instructed using EQ improvement program. Two groups were treated for 42 hours during 14 weeks. Two way ANCOVA and correlation analysis was performed using the SPSS. The results indicated that students who received EQ program got higher EQ and their science anxiety was lowered than students who were in a control group(p<.05). EQ program was not significantly effective on science attitude than the traditional instruction but, in the domain 'the enjoyment of science class' it was effective(p<.05). EQ program was significantly effective on students' achievement than the traditional instruction(p<.05).

This study was conducted to investigate the effect on Brain Quotient from inhalation of blended oils. The subjects of the study were 64 people aged 20 to 59 years, with 32 in the experimental group and 32 in the control group. Blended oil with six aromas (Lavender, Bergamot, Mandarin, Lemon, Cedarwood, Roman Chamomile) was given to the experimental group, and Jojoba oil was given to the control group, for 30 minutes. Before and after the experiment, BQ tests (SRQ, BRQ, ATQ, ACQ, EQ, ASQ, CQ, and BQ) from the experimental group and the control group were compared and analyzed using a brain-training machine (NeuroHarmony S). There was a significant difference between the experimental group and the control group in three out of the eight tests analyzed ATQ (p<.05), ACQ (p<.05), BQ (p<.05). In other words, aromatherapy improves concentration and memory by increasing attention, and helps to maintain mental activity, thinking ability, and behavioral balance. BQ also represents a comprehensive brain function, and aromatherapy is a good way to maintain human mental and physical health.

Recently, many organizations are utilizing the team system. However, researches on a technique for efficient and effective feedback to improve a team performance is few. This study compared the relative effects of individual and group feedback on the quantity and quality of work performance. The task was to type English documents on a PC computer and both the number of words typed (quantity) and the percentage of correctly typed words (quality) were measured. Mixed design was adopted and 48 participants were randomly assigned to either individual or group feedback condition. Each group consisted of three participants and completed four sessions together. Under the individual feedback condition, each participant was provided with information on his/her own work performance, while under the group feedback condition, three participants were provided with information on their total work performance. Results showed that both feedback were effective to increase the quantity of performance. However, the effect size of treatment was more high under the group feedback than individual feedback. In addition, the accuracy of typed words was significantly improved only under the group feedback condition. Therefore, the group feedback was more effective and efficient than individual feedback to increase team performance. However, more studies are needed to generalize these results, especially, it is necessary to consider the cultural differences and type of task in the future studies.

The cooperative learning movement began as parts of the desegregation process in America, aiming at increasing academic achievement and social skills among diverse students. Cooperative learning may be defined as a classroom learning environment in which students work together in small heterogeneous groups. Although many studies have shown the effectiveness of cooperative learning in a variety of subjects, relatively few have focused on biology. In this study, we investigated the effects of cooperative learning on students' achievement and attitude of middle school biology students. For this purpose this study compared three sections. In one section, a cooperative learning strategy was used. Second section was taught in small groups and the third section was instructed in the traditional method. The unit 'Structures and functions of animals' was used. A total of 188 students were included in this study. These classes were treated for 10hours during 10weeks from September 1 to November 28, 1999. The pretests-posttests control group design was applyed. An analysis of covariance(ANCOVA) was used as the data analysis procedure. Significant differences were found in the achievement and the attitude of students using cooperative learning strategy(p<.05) when compared to traditional classroom structure and small group learning. Cooperative learning was more effective in the low-ability and average-ability students than the high-ability students in the science achievement. Cooperative learning is effective in both male and female students. And students in the cooperative group achieved better than those in other groups in affective, behavioral, and intention-cognitive domain of science attitude.

This paper examined how consumers' attitude toward the telecommunication expense was affected by news reports through the experiment. Participants were randomly assigned to one of four group (control group, high-expense-claimed-media group, low-expense-claimed-media group, and both-exposed-media group), and asked to indicate credibility & neutrality toward media report, similarity between media report, and their own thought, their attitude toward the telecommunication expense. The result of ANOVA showed that the high-expense-claimed-media was perceived more credible and neutral than the low-expense-claimed-media. ANCOVA was conducted to eliminate the impact of similarity between media report and their own thought on the evaluation of credibility & neutrality toward media report, and the result showed that there was no difference. Also, participants evaluated the telecommunication service so expensive, regardless of what kind of media reports they were exposed. We found that consumers' prior belief, which telecommunication service was expensive, might interrupt consumers' learning process for new information from media. To resolve the social pressure about mobile service rate-cutting, it is necessary to investigate how to dampen consumers' stereotype about the telecommunication expense. The future research using the framing effect could be considerable.

This study was conducted to examine the effects of auricular acupressure on quality of sleep and depression. Adults who had insomnia for over 1 month were recruited. Participants were distributed randomly to the experimental group(n=22) and the control group(n=22). The experimental group received auricular acupressure on Shen men(TF2), insomnia 1(SF4), insomnia 2(SF1), and anti-depression(LO8) for 1 week. The contrast group received sleep hygiene education. The mean differences of the quality of sleep were 4.05±2.52 in the experimental group and 1.45±3.77 in the control group. Auricular acupressure significantly decreased insomnia in the experimental group compared to the control group(t=3.07, p=.004). Depression scores after acupressure were not different between the experimental group and the control group. After controlling the religion as a covariate, the mean difference of depression in the experimental group was higher than the control group(F=4.22, p=.046). In conclusion, auricular acupressure decreased insomnia and depression. Therefore, further studies on different acupressure points such as shen men, jiao gan, heart, pi zhi xia, and endocrine are recommended.
