Study of middle school science textbooks recommended for use with a constructivist syllabus in Queensland schools.

Christine Milne Unknown Date (has links)
This thesis describes an analysis of science textbooks, eight years after the implementation of the Years 1-10 Queensland Science Syllabus, which suggested a move towards constructivist teaching in Queensland schools (QSSC 1999). The textbooks have been analysed for evidence of constructivism, and this has led to recommendations for writing better textbooks. This thesis has been written in five chapters. In Chapter 1, a review of literature develops a conceptual framework, which is the basis of this research. Chapter 2 describes the process used to develop its methodology, and Chapter 3 presents the results of this analysis. Chapters 4 and 5 discuss the findings of this research and its implications for textbook content and design. In the literature review the themes of constructivism and the nature of science and the use of textbooks by teachers are explored. It suggests that textbooks continue to be central to developing curriculum, that they are used as a reference and as an independent learning tool, rather than as a guide to enacting curriculum. It also shows constructivist teaching closely aligns with authentic science, that it moves school science closer to that practised by scientists, and that it can engender improvements in teaching practice and in student interest. The data from this research has been collected using an analytical grid developed from three successive trials, after the literature review showed no previously developed analytical grid was suitable. In this final version of the grid, Likert scales are used to observe four dimensions of constructivism in textbook activities: coherence (use knowledge and concepts in a range of contexts), student-centredness of inquiries, language used and analysis questions to practice making new knowledge claims. The unit of analysis was ecology chapters of four middle school science textbooks. The research questions asked in this study are as follows: • Is a constructivist approach discernable in the textbooks reviewed in terms of the four dimensions of constructivism identified in the literature review? • What elements of constructivism are readily identifiable, and therefore are easily included in textbooks? • What elements of constructivism are not discernable? The results of this research have been synthesised and show no textbook could be considered constructivist, although one textbook had inquiries that could be considered exemplary. Two of the textbooks had no claim to be constructivist because they lacked inquiries, and this is where students experience the methods of scientists and practise making knowledge claims.   Other conclusions of this research include the following: •All textbooks reviewed were deficient in at least one dimension of constructivism, and those with one inquiry cannot be constructivist; •Activities and contexts made textbooks more coherent; •Technical terms were reduced compared to what has been traditionally covered by textbooks, however technical terms are also essential to scientific literacy and need to be used appropriately; •Most methods of inquiries are prescribed, so they do not allow students to solve problems in their own relevant contexts; even in those textbooks with more inquiries; •There was little evidence of hypothetico-deductive reasoning in inquiries rather data collection and simple analysis were usually suggested. Guidelines for writing better textbooks have become apparent from this research. Coherent textbooks are inherently constructivist because they apply concepts across contexts, and have more inquiries. Inquiries with a rigorous, authentic hypothetico-deductive approach arise naturally when the methods, concepts and language of science are applied in contexts that students are likely to find relevant and interesting, and where real-life problems need to be solved. Adopting these recommendations could lead to textbooks being more centrally positioned in enacting curriculum than now, because they are more likely to be constructivist (and represent the best thinking in the field).

School Climate in the School Choice Era: A Comparative Analysis of District-Run Public Schools and Charter Schools

Duszka, Christopher Damian 10 September 2018 (has links)
Comparative analyses of district-run public schools and charter schools are limited to performance outcomes. There is a dearth of research on how the school-types vary on factors consequential to performance such as school climate. Public-private distinctions, such as in organizational autonomy, value orientations, funding structures, and management practices, could result in school climate dissimilarities between district-run public schools and charter schools. The aim of this dissertation is to assess the influence organizational factors have on school climate and determine if school-type affects school climate. Student and staff school climate survey data from the Miami-Dade school district were utilized for this dissertation. Structural equation modeling was employed to test theoretical models of students’ and staffs’ perceptions of school climate using data from 2001-2002 through 2015-2016 academic years. Within-between effects panel regression was utilized to test the effect of school-type on school climate constructs over time using data from 2005-2006 through 2015-2016 academic years. The structural equation results demonstrate that milieu, ecology, culture, and organizational structure influence students’ and staffs’ perceptions of their schools’ climates. Ecology has the strongest association with students’ perceptions of school climate. Job satisfaction, a part of milieu and culture, has the strongest association with staffs’ perceptions of school climate. The results indicate that the theoretical models of school climate employed by this study are sound. The within-between effects panel regression results demonstrate that characteristics inherent to school-type have a plausible influence on students’ perceptions of school climate, but not for staff. Charter school students rated their school climates more favorably than traditional public schools, but when other factors are controlled, traditional public schools and magnet schools had more favorable ratings. Public-sector values, collective bargaining, and school district oversight may be beneficial to schools’ climates. This dissertation underscores the impact management and funding structures have on school climate. The author recommends that the school climate concept and evaluations of schools’ organizational practices be incorporated into school improvement policies. The milieu, culture, ecology, and organizational structures of schools should be reviewed when assessing school quality.
