Item 以巢狀概念模式探究高中生之科學學習–科學認識觀、後設認知知覺、科學學習概念及其科學評量概念(2009) 李旻憲; Min-Hsien LeeThe purpose of this study was to deeply investigate students’ nested ecology regarding science learning from multidimensional perspectives (i.e., the interrelations among scientific epistemological beliefs, metacognition, conceptions of learning science, and conceptions of science assessment). To this end, this study performed the quantitative method to initially explore the interrelations among scientific epistemological beliefs, metacognitive awareness, and conceptions of learning science. Then, the qualitative method was conducted to deeply investigate the interplays among scientific epistemological beliefs, conceptions of learning science, and conceptions of science assessment and to clarify the nested ecology model. In addition, the role of metacognitive awareness on scientific epistemological beliefs and conceptions of learning science and science assessment were discussed through both quantitative and qualitative results. The quantitative part of the study was conducted with a sampling pool of 240 tenth graders. And, those students’ responses from three questionnaires were used to yield some quantitative indicators (i.e., scientific epistemological beliefs, metacognitive awareness, and conceptions of learning science) and to clarify the interplay between those variables. In general, the quantitative results revealed that students having more sophisticated scientific epistemological beliefs tended to show higher metacognitive awareness while learning science and to express more constructivist-oriented conceptions of learning science. In particular, as long as the students have more sophisticated beliefs about the justification of knowledge; they may tend to express much higher metacognitive awareness and to embrace the constructivist conceptions of learning science. For qualitative part of study, 60 representative students selected from the sampling pool were deeply interviewed about their scientific epistemological beliefs (including beliefs about the nature of knowledge and beliefs about the nature of knowing), conceptions of learning science, and conceptions of science assessment. This study found that most selected students expressed the empiricist beliefs about the nature of knowledge. Through the phenomenographic analyze of selected students’ interview responses, seven categories of conceptions of learning science (i.e., memorizing, preparing for tests, practicing the experiments, the increase of knowledge, applying, understanding, and seeing in a new way) and six categories of conceptions of science assessment (i.e., reproducing knowledge, rehearsing, revealing the learning status, improving learning, applying, and the justification of knowledge) were identified in this study. Moreover, the qualitative results seemed to reveal that, on the one hand, the selected students’ beliefs about the nature of knowing seemed to have greater power to explain students’ conceptions of learning science than their beliefs about the nature of knowledge. On the other hand, their beliefs about the nature of knowledge seemed to more relate to their conceptions of science assessment. This study also implied that students expressing more mature conceptions of learning science tended to hold more cohesive conceptions of science assessment. Furthermore, the qualitative part of this study identified three major forms of students’ nested ecology regarding learning science, that is the complete, partial, and divergent nested ecology. In particular, nearly half of 60 representative students were categorized as the complete nested ecology.Item 高一地球科學教室學習環境之初探(2004) 李旻憲; Min-Hsien LeeThe chief purpose of this study is to explore the classroom learning environment (LE) at secondary school, includes students’ preference toward classroom LE which focusing on students’ viewpoints (perceptions and fitness) and specifically dealing with student-centred and teacher-centred orientation by an alternative, transverse or macrocosmic standpoint. A pre-test post-test survey design involving 1,234 students from 34 classes enrolled in a compulsory earth science course at 14 schools was adopted. Each student responded to the earth science classroom learning environment instrument (ESCLEI) and completed the earth science learning outcomes questionnaire (ESLOQ) in summer semester from September 2003 to February 2004. We used a class as the unit of analysis in this study. The results showed that students’ preferred and perceived (actual) classroom LEs are much more oriented toward teacher-centred setting then toward the student-centred setting in both pre- and post-test, in spite of the preferred classroom LEs revealed by students’ responses on both subscales are quite similar to each other. The classroom LEs settings are chiefly teacher-centred oriented, although students were also fond of the student-centred settings and it still had a certain extent gap between their preferred and actual (perceived) classroom LEs. Students’ preferred classroom LEs on both subscales tend to regress when they were taught during a semester and their perceived (actual) classroom LEs on teacher-centred orientation have a similar outcome. It is worthy noted that students perceived (actual) much more student-centred oriented classroom LE when they were taught during a semester. Moreover, students’ person-LE fitness (PEF) on both subscales tend to regression when they were taught during a semester, especially in student-center. Results form the simple correlation (r) revealed that there were some positive relationship between classroom climate vector in student-center (CVS) and the diversities of leaning outcomes (i.e. attitude and achievement), and were no significant relationship between CVT and the diversities of learning outcomes. It seem to indicate that the diversities of learning outcomes were tended to increase which if teacher didn’t fitted for students’ perceptions on student-centred orientations in light of current study. Overall, this study revealed the present structure of classroom LE at the secondary school earth science classroom, and it also revealed students’ perceptions and the fitness in classroom LE. Principals and supervisors may use it to help teacher improve their classroom environments. It is noted, however, that there were some relationships between CV and diversity of learning outcomes; it still needed some further investigations to interpret the data given form present study.
