This exploratory mixed methods study addressed the types of gains students made when engaged in one of two forms of inquiry. Gains were measured on three levels: conceptual understanding, the process of scientific investigation, and use of practical reasoning skills. One hundred-thirty 8th grade students from a rural public school in East Texas participated in this study. Classes of students were randomly assigned to one of two treatment groups: guided inquiry or authentic student research learning. Non parametric statistical analysis and constant comparative qualitative analysis were used to triangulate pre-tests and post-tests, student journals, and student drawings to address the research questions. Findings support greater gains in conceptual understanding of domain specific content in a highly scaffolded guided inquiry. Further authentic scientific research learning was more effective for developing understanding of scientific investigation as a process and application of knowledge through practical reasoning skills.

The purpose of this concurrent mixed methods study was to investigate the impact on high school students' knowledge and attitudes regarding astronomy and beliefs about the nature of science after participating in an extended authentic, inquiry-oriented, research experience studying variable stars using a specifically designed curriculum guide "In the Hunt for Variable Stars." The study gathered quantitative data using a pretest posttest strategy on a modified form of an existing questionnaire called Students Attitudes Toward Astronomy and four student-supplied response content surveys. Qualitative methods included analysis of researcher's field notes, naturalistic observations, formal interviews, and students' artifacts. The methods and results of this study provided important baseline information to measure cognitive and affective changes resulting from an authentic scientific research experience for high school students.Ninety students participated in a targeted instructional sequence and their attitudes and knowledge were compared to 50 students in a comparable science course who were not provided an authentic research experience. The results obtained in this study strongly suggest that participation in research is successful at significantly increasing content knowledge. All four content surveys showed statistically significant increases for students in the intervention group as compared to the students in the non-intervention group. Qualitative results demonstrated that both groups of students initially held naïve ideas about science and astronomy. After participation in the intervention, the most dramatic changes were observed in students' understanding of astronomy content. No substantial change was seen in students' attitudes toward Astronomy and science but there is evidence of some limited impacts on beliefs regarding the nature of science.In combination, the data resulting from this mixed-method study lend considerable weight to claim in contemporary science education reform that students will learn and more scientifically accurate knowledge of astronomy after participating in authentic inquiry experiences.

This research has taken place at a time when governments in Australia, like governments throughout the Western world, have given higher priority to funding teachers’ professional learning. This support for teachers’ learning tends to be informed by standards-based ‘reforms’ of schooling, underpinned by narrowly individualistic paradigms of teacher knowledge and enacted in managerial models of professional development. The effectiveness of this ‘PD’ for individual teachers tends to be measured in rigid accountability regimes. My study is a conceptual, grounded and reflexive inquiry into teachers’ professional learning in Victoria, Australia. Central to the study is a multi-levelled account of a small group of English-literature teachers at Eastern Girls’ College, in Melbourne, Australia, learning about literary theory over a period of fourteen months. These teachers operate within an institutional setting in which they are certainly expected to be accountable in managerial terms, and yet they can be seen negotiating a very different paradigm of professional learning. In my account of their learning in this study, I develop a model of inquiry-based professional learning that offers a richly dialogic alternative to narrowly individualistic paradigms of professional knowledge and professional development.

This research has examined the role of teacher presence in online education. The research has been guided by two research questions: 1) are there challenges to consistently establishing teacher presence in online courses?; and 2) can the role of teacher presence be assumed, in part, by the learning medium? The Community of Inquiry framework as outlined by Garrison, Anderson, and Archer (2000) has framed the discussion about the role of teacher presence in online education. Three research projects are presented to explore the research questions. The first study is a case study that examines twelve online instructors’ engagement and experience teaching online over a year at the University of Saskatchewan. The next study builds on that study by exploring teacher engagement and satisfaction of 28 online instructors at the University of Regina using survey techniques. Together the studies suggest that teacher engagement in online courses might be affected by the culture of the university. The third study addresses the second question by creating the NECSUS social computing environment, which assumes some functions of teacher presence. The NECSUS system has been tested in a graduate level ethics courses and demonstrates that it has the potential to support a community of inquiry. This is further demonstrated by the presentation of a NECSUS-like system design that could be modified to support a non-formal learning community for a commercial online education course for snowmobile safety. The outcome of this research suggests that the Community of Inquiry framework can inform the design of learning environments and that assume some responsibilities traditionally assumed by the instructor.

This study compared middle school (i.e., fifth, sixth and seventh grade) students’ mental models of the day/night cycle before and after implementation of three inquiry-based treatments. The three treatments were classified as 1) structured inquiry, 2) guided inquiry, and 3) student-directed inquiry. All three treatments used Starry Night Middle School interactive simulation software to investigate the phenomenon of the day/night cycle. Additionally, all three treatments were based on two researcher-developed lessons using Starry Night Middle School. The participants were 145 fifth, sixth, and seventh grade students who were purposively selected from a public school in a U.S. state. For the purpose of this study, the students remained in their classrooms. There were three classrooms per grade level. Those classrooms were randomly assigned to one of the three treatments. Students’ scores on a pretest, immediate posttest, and delayed posttest were analyzed. Students from a purposive sample were interviewed after the pretest, immediate posttest, and delayed posttest to clarify student mental models of the day/night cycle. The students were chosen based upon their score on the multiple-choice test. Seven of the selected students were in the Structured Inquiry group. Eleven of the selected students were in the Guided Inquiry group. Five of the selected students were in the Student-directed Inquiry group. First, the comparative effects of Structured Inquiry, Guided Inquiry, and Student-directed Inquiry on middle school students’ mental models of the day/night cycle immediately and three months following the intervention revealed no statistical difference among the three treatments. Time, however, appeared to have a significant negative effect on students’ mental models of the day/night cycle. Second, inquiry groups did not differ significantly in their mental models. Third, there was no interaction between starting mental model and the type of inquiry. The major findings demonstrate that all three treatments promote learning, but that no one treatment is more effective than another.
