An Assessment of Environmental Literacy and Analysis of Predictors of Responsible Environmental Behaviour Held by Secondary Teachers in the Hualien Area of Taiwan     

Shih‐Jang Hsu  Robert E. Roth 《Environmental Education Research》1998,4(3):229-249

This study assessed teachers' environmental literacy and analysed predictors of teachers' responsible environmental behaviour (REB). A nine page instrument was administered by mailed questionnaire to 300 randomly selected secondary teachers in the Hualien area of Taiwan with a 52.3% effective response rate. As a result of stepwise multiple regression analyses, the most parsimonious set of predictors of REB for all teachers included: perceived knowledge of environmental action strategies (KNOW), intention to act, area of residence and perceived skill in using environmental action strategies (SKILL, total r² = 0.3867). For urban teachers, the most parsimonious set of predictors included: intention to act, SKILL, major sources of environmental information and membership in environmental organisations (total r² = 0.4711). For rural teachers, the most parsimonious set of predictors included: KNOW, intention to act and perceived knowledge of environmental problems and issues (total r² = 0.3200). Implications for programme development and instructional practice are presented. Recommendations for further research are also provided.  相似文献   

Single-cell attachment and culture method using a photochemical reaction in a closed microfluidic system

Recently, interest in single cell analysis has increased because of its potential for improving our understanding of cellular processes. Single cell operation and attachment is indispensable to realize this task. In this paper, we employed a simple and direct method for single-cell attachment and culture in a closed microchannel. The microchannel surface was modified by applying a nonbiofouling polymer, 2-methacryloyloxyethyl phosphorylcholine (MPC) polymer, and a nitrobenzyl photocleavable linker. Using ultraviolet (UV) light irradiation, the MPC polymer was selectively removed by a photochemical reaction that adjusted the cell adherence inside the microchannel. To obtain the desired single endothelial cell patterning in the microchannel, cell-adhesive regions were controlled by use of round photomasks with diameters of 10, 20, 30, or 50 μm. Single-cell adherence patterns were formed after 12 h of incubation, only when 20 and 30 μm photomasks were used, and the proportions of adherent and nonadherent cells among the entire UV-illuminated areas were 21.3%±0.3% and 7.9%±0.3%, respectively. The frequency of single-cell adherence in the case of the 20 μm photomask was 2.7 times greater than that in the case of the 30 μm photomask. We found that the 20 μm photomask was optimal for the formation of single-cell adherence patterns in the microchannel. This technique can be a powerful tool for analyzing environmental factors like cell-surface and cell-extracellular matrix contact.  相似文献   

Significant life experiences affect environmental action: a confirmation study in eastern Taiwan     

Shih‐Jang Hsu 《Environmental Education Research》2009,15(4):497-517

Two field studies form the basis of this article. The major purposes of Study 1 were to examine significant life experiences affecting the cultivation of environmental activists in eastern Taiwan, and to reconstruct the life paths followed by those active people who engaged in effective environmental action. 40 usable autobiographical memories were collected and content‐analysed to derive 17 significant life experiences. Based on the 17 accounts, a quantitative questionnaire of 24 items on significant life experiences variables was developed for Study 2. Four hundred and thirty valid questionnaires were analysed. Eighty two respondents with a high level of environmental action were determined to be environmental activists, and 153 with a low level of environmental action were determined to be people apathetic towards environmental protection. It was found that the significant life experiences identified in Study 1 could effectively distinguish environmentally committed people from those apathetic to environmental protection. Study 2 also found that 54.6% of the variances in environmental actions could be explained by the significant life experiences.  相似文献

A New Autonomy-Supportive Way of Teaching That Increases Conceptual Learning: Teaching in Students' Preferred Ways     

Hyungshim Jang  Marc Halusic 《Journal of Experimental Education》2016,84(4):686-701

We tested the educational utility of “teaching in students' preferred ways” as a new autonomy-supportive way of teaching to enhance students' autonomy and conceptual learning. A pilot test first differentiated preferred versus nonpreferred ways of teaching. In the main study, a hired teacher who was blind to the purpose of the study taught 63 college-age participants in small groups the same 48-minute lesson in one of these two different ways, and we assessed participants' perceived autonomy support, autonomy-need satisfaction, engagement (self-report and rater scored), and conceptual learning (self-report and rater scored). Multilevel analyses showed that participants randomly assigned to receive a preferred way of teaching perceived the teacher as more autonomy supportive and showed significantly greater autonomy-need satisfaction, engagement, and conceptual learning. Mediation analyses using multilevel modeling for clustered data showed that this way of teaching enhanced conceptual learning because it first increased students' autonomy. We conclude that “teaching in students' preferred ways” represents a way of teaching that increases students' autonomy, engagement, and conceptual learning.  相似文献   

The Effects of Attachment Styles and Efficacy of Communication on Avoidance Following a Relational Partner's Deception     

Su Ahn Jang 《Communication Research Reports》2013,30(4):300-311

This investigation examined the effects of attachment styles and efficacy of communication on avoidance following a relational partner's deceptive communication. Efficacy of communication was explored as a mediating variable. Students (n = 123) who reported being deceived by their relational partner were recruited for the study. The data revealed that, compared to individuals with other attachment styles, those with a high anxious/ambivalent attachment tendency were more likely to avoid discussing the deception with their partner. In addition, efficacy of communication was negatively associated with avoidance. The results further revealed, however, that efficacy of communication mediated the link between attachment and avoidance. More specifically, highly anxious/ambivalent individuals were more likely to perceive relatively low efficacy of communication, and such perception, in turn, influenced their avoidance. Findings of the study provide an explanation for the association between attachment and avoidance.  相似文献   

The Effects of Incorporating Web‐assisted Learning with Team Teaching in Seventh‐grade Science Classes     

Syh‐Jong Jang 《International Journal of Science Education》2013,35(6):615-632

Due to the implementation of a 9‐year integrated curriculum scheme in Taiwan, research on team teaching and web‐based technology appears to be urgent. The purpose of this study was incorporated web‐assisted learning with team teaching in seventh‐grade science classes. The specific research question concerned student performance and attitudes about the teaching method. Two certified science teachers and four classes of the seventh graders participated in this study. It used a mixed methods design, incorporating both quantitative and qualitative techniques. The main data included students’ scores, questionnaires, teachers’ self‐reflections, and the researcher’s interviews with teachers. The results showed that the average final examination scores of students experiencing the experimental teaching method were higher than that of those receiving traditional teaching. The two teaching methods showed significant difference in respect of students’ achievement. The research had limitations because of students’ abilities of data collection, computer use, and discussion, but more than one‐half of the students preferred the experimental method to traditional teaching. However, team teachers would encounter the problems of technology ability, time constraints, and entrance examination pressure.  相似文献

Effects of Cognitive Flexibility Theory‐based instruction on Korean high school history teaching     

Soojung Jang 《Distance Education》2000,21(1):136-161

Understanding complex conceptual relationships is crucial for Korean high school history learning. The motivating hypothesis for this study is that a Cognitive Flexibility Theory‐based Hypertext instructional module will promote acquisition of advanced knowledge associated with complex conceptual relationships. This study focussed on improving Korean history teaching and learning in terms of these learner characteristics based on Cognitive Flexibility Theory, an influential constructivist approach in the field of educational technology. A referential hypertext program based on Spiro and his colleagues’ (1988, 1990) Cognitive Flexibility Theory (CFT) was developed for this study. Three learning programs were presented: (1) Cognitive Flexibility Theory‐Based Hypertext (CFTH), (2) hierarchical hypertext, similar to CFTH except for its hierarchical node connections, and (3) a textbook representing the typical Korean high school history instruction process. The effects of these three treatments on history achievement were examined in terms of post‐test item characteristics. Independent variables were students’ IQ, and prior knowledge and motivation toward each learning program that was measured after the treatment. Students’ achievement was the highest among three groups, especially in complex items: comparison, analysis and synthesis. In the CFTH group high IQ and low PK students’ achievement was most improved, and motivation was the chief influential factor in explaining the achievement.  相似文献
