The extended science investigations, comprehensive investigations contrasted with exercises of process skill components and cookbook style experiments, should be pursued for giving opportunity of more authentic science activity. The characteristics of the extended investigation tasks were emerged from critical argument on school practical work. And one of important educational objectives in students' investigations is to achieve motivation for investigation. The purpose of this study is to explore how the characteristics of the extended investigation tasks, that is practical context, openness and continuity, affect middle school students' motivation for investigation. On the basis of questionnaire results and students' school science achievement, ten students were interviewed to see the change of motivation for investigation and its causes while they perform two textbook investigations and four extended investigation tasks. Among the interviewees, the students who showed positive motivation for the extended investigations were critical about textbook experiments as they are just confirmations of theories and perceived practical context and openness as the main causes of their positive motivation. The students who showed negative motivation for extended investigations preferred textbook experiments as there was enough guidance from teacher and textbook-centered learning. They recognized the openness of the tasks as a main reason of their negative motivation for investigation. Some students showed negative responses about continuity of the extended investigation tasks but continuity was not recognized as a main cause for their motivation for investigation.

In this study. 'extended science investigation' was conceptualized as a comprehensive science investigation contrasted with exercise of process and skill component and cookbook style experiment. The extended investigations should be pursued for giving opportunity of more authentic science activities in school science. And one of important educational objectives in students' science investigations is to achieve motivation for investigation which drives and triggers further investigations. It can be discerned as positive and negative by its direction and also as internal and external by its cause. The purpose of this study was to describe change of students' motivation for investigation while they were performing the extended science investigations. The subject was 128 7th grader attending coeducational school in Seoul. Questionnaires and students' reports were analysed complementarily to describe students' motivation for investigation. The number of students who showed positive motivation for investigation did not increase in the developed extended investigations than in the directive investigations in textbook, but the cause of positive motivation for investigation has changed largely from task-exclusive factors to task-inclusive factors. In case of negative motivation for investigation, regardless of the kind of investigation task, task-inclusive factors were recognized as the main causes. Among those whose motivation changed during successive extended investigations, the students who showed change from negative to positive were more than the reverse. And the number of positive intrinsic motivation for investigation was increased at the second half of the extended science investigations. So it can be said that there was a desirable change of motivation for investigation at the second half the extended science investigations.

Purpose: The purpose of this study is to grasp the concept of ethical consumption that is inevitably one of the behaviors of consumption and to find factors affecting ethical consumption. The most special idea of this study is including motive in the research model. And motive will influence the factors affecting the intention to behave. Research design, data, and methodology: Considering variables affecting ethical consumption, we first adopted the T theory of Planned Behavior. There are three variables of attitude, subjective norm, and perceived behavior control in the model. In addition to variables used in the Planned Behavior Theory, ethical duty, self-identity, motive, neutralization, ambivalence are included in the study. Questionnaires are made for survey, and investigation was conducted from 1th March to 11th of March. Total 360 copies are used for analysis. SPSS version 23 was used for analysis. Results: Study results show that first, the variables of attitude, subjective norm, perceived behavioral control, ethical duty, self-identity are turned to be statistically significant factors affecting ethical consumption intention. In this study, we defined the ethical consumption as voluntary, self-sacrifice needed, and additional efforts required behavior, therefore motive thought to be needed at fist for individual consumer to form intention. For neutralization and ambivalence, neutralization does not affect ethical consumption directly or indirectly, but we found ambivalence has moderating effect while motive affecting attitude, perceived behavior control, self-identity and has moderating effect while attitude, subjective nom, perceived behavior control, self-identity affects intention. Ambivalence means individual consumer's thought or preoccupation toward ethical consumption, in other words, consumer may have fiendly or unfriendly, positive or negative impression to it. Overall, motive and ambivalence are important factors for ethical consumption. Motive plays some role from the start influencing main factors affecting ethical consumption. Ambivalence also functions by moderating variables. Thinking of ambivalence taking account of essence of ethical consumption, some consumers may have pretext or justification for not doing ethical consumption which may again annoy themselves. Conclusions: In conclusion, for intention to ethical consumption to be formed motive should be activated beforehand and ambivalence should be considered. Negative ambivalence toward ethical consumption should be removed and positive ambivalence should be developed.
