<p> Although research is limited on the effectiveness of co-teaching as a service delivery model for students with disabilities, through observation, many educators have reported positive outcomes with co-teaching (Beninghof, 2011). This case study was designed to examine the implementation of co-teaching in an elementary magnet school in a Midwestern school district driven by science, technology, engineering, arts, and mathematics (STEAM) and with a strong emphasis on personalized learning. General education teachers, special education teachers, and administrators were interviewed three times during the initial implementation school year. In addition, journaling was documented by three of the participants, and co-teaching fidelity checks were completed by the school district&rsquo;s Executive Director of Special Services. After information was gathered and analyzed, it was discovered both students with and without disabilities benefit from co-teaching as a service delivery model. It was also noted there are similarities between the benefits and challenges in a traditional co-taught classroom and a co-taught class in a STEAM elementary school with an emphasis on personalized learning. The benefits of co-teaching far outweigh the detriments. It was further discovered the success of co-teaching is attributed to the pairing of co-teaching partnerships. Finally, the participants shared the need for special education administrators to play a more active role in professional development and the sustainability of co-teaching.</p><p>

Although science is viewed by some as objective, analytical and unaffected by morals and values, the practice of science does raise many ethical issues. From an ethical standpoint, science teachers have an obligation to ensure that their students develop the skills to enable them to evaluate and make decisions about ethical issues associated with scientific advances so that they can make informed choices as adults. An appropriate forum for such a pedagogical concern is the subject of bioethics education.The purpose of this doctoral study was to investigate the teaching of bioethics in science. Specifically, the study attempted to evaluate the effectiveness of a range of innovative pedagogical strategies utilised by teachers who were incorporating bioethics education into their secondary science curricula. Bioethics education is concerned with enabling students, firstly, to appreciate the range of ethical issues associated with the life sciences and, secondly, to develop decision making skills based on ethical theories.Using an interpretive case study approach underpinned by a constructivist theoretical framework, I examined the teaching practice of three science teachers in different school systems. Each of these teachers taught Year 10 or Year 11 science courses that included a bioethics component. The research process was informed by an ethic of care and the constructivist criteria of credibility, transferability and ontological authenticity.As a result of the early data generated, I adopted the role of a bricoleur and used alternative research methods to pursue emergent research questions. I developed a survey consisting of four bioethical dilemmas. Bioethics students were asked to resolve each of the dilemmas and provide reasons to support their decisions. Using an ex post facto research design, I compared students who had studied bioethics with a comparison ++ / group of students who had not. I also wrote narrative tales in an endeavour to provide an authentic account of the learning of individual students. Commentaries on the tales, by students and teachers, helped to enrich my understanding of students' learning experiences in the bioethics classes.The research findings are presented as 'inferences', a term which acknowledges the context dependent nature of the data generated. Five themes emerged from the data analysis which, together, indicate (1) the nature of potentially successful teaching strategies for bioethics education and (2) obstacles to students' successful engagement in learning bioethics: teacher attributes; design of bioethics courses; student attributes; impact on student learning; and physical and social constraints. Another key finding concerns the difficulty facing researchers who wish to 'measure' the impact of bioethics teaching on student learning.All three teachers displayed potentially successful teaching strategies. They were committed to the inclusion of bioethics education in their science courses. They had clearly articulated pedagogical goals related to bioethics education. They endeavoured to create safe learning environments in which students could clarify and explore their developing ethical values. When students expressed extreme views, the teachers, through careful questioning, challenged them to consider alternative ethical positions.In relation to the design of bioethics education courses, most of the learning activities in which students participated were based on small group and whole-class discussion (e.g., role plays, oral presentations). These activities provided opportunities for students to examine a topic in depth. Importantly, students were provided with information to help them understand the scientific content area before they could appreciate the associated ethical issues.In ++ / the three cases, it appears that bioethics education had a variable effect on student learning. Attributes were identified that may have influenced student engagement in opportunities to learn bioethics: the students' moral maturity, academic ability, attitude to learning, beliefs about science and ethics, family and religious background.Evidence suggests that exposure to bioethics education can affect favourably students' attitudes to science. However, the results of the bioethical dilemma survey suggest that, on average, there was no difference in the way that students resolved dilemmas, regardless of whether or not they had been exposed to bioethics education. Although there was considerable variation amongst students, most of the students' responses differed from those of experts in that the students tended to focus solely on the rights of individuals, without considering the long term consequences of their decisions.Constraints were identified that may adversely affect the impact of bioethics education in science: scarcity of resources, including insufficient teaching time; and, amongst science teachers, lack of expertise in the content areas that raise bioethical issues and lack of experience in the types of learning activities appropriate for bioethics education.The findings of this research study are significant as they highlight important issues that may need to be considered by curriculum planners and science teachers who wish to incorporate bioethics education into science curricula.

In this thesis, I present a modest polemic about science cultural myths and their influence on school science. My analysis is critical because I seek ultimately to free teachers and students from repressive science cultural myths. Within this thesis, my critical analysis reveals the character of prevailing science cultural myths and provides evidence of their power within school science to legitimate specific forms of science knowledge to the exclusion of other forms. Subsequently, I propose a philosophical science framework for enabling teachers and students of science to transform their teaching and learning practices. These three aspects provide the framework of my thesis.The first step in my critical analysis involved the identification of the major characteristics of cultural myths. A cultural myth is a shared network of beliefs that regulate and order social practices that forgets how it was created. I argue that myths are characterised by their apparent invisibility once their historical evolution has been forgotten. Using this definition, I then examined the genesis of myths during the emergence of experimental philosophy in Western Europe in the 17th century and identified the following science cultural myths: myths associated with a naive realist perspective of observation and experimentation; myths that present science as justified, true knowledge; myths of a mechanical cosmology; and myths associated with the apparent transparency of language.Next, I examined literary aspects of school science, specifically textbooks, to search for the presence of these science cultural myths. I argue that the science presented in school science can be described as science stories, and that within these stories there is an iterative relationship between the 'facts' selected for the telling and science cultural myths. I identified four different types of stories that I ++ / call heroic, discovery, declarative and politically correct science stories, each of which helps to maintain specific myths of science. Using literary theory, I developed an approach to analysis and reconstruction of school science stories that can be used by teachers and students to assist them to transform science stories. Such an approach would help students to hear the multiple voices of science, rather than the mythical single dominant voice.I examined also the power of science cultural myths to assist or enforce the enculturation of pre-service teachers into school science. This examination was a twostep process. Firstly, using repertory grid analysis and interviews, I identified the dominant notions of science held by pre-service teachers before they began teaching Later, in follow-up interviews conducted after they had gained some teaching experience, I obtained critical insights into the interaction between the notions of science held initially by the pre-service science teachers and those endorsed by the school science culture. The results indicate the power of science cultural myths to obligate pre-service teachers to adopt uncritically specific practices within school science.Finally, I propose a philosophy of science for science education that consists of five key referents: construction, tentativeness, dynamism, neopragmatism and critique. This holistic philosophy offers science educators a framework for evolving a school science culture that is critically aware of science cultural myths and their power and that can promote the multiple voices of science.

The growing diversity of school populations around the world means that for many students the language of instruction in mainstream classrooms is not their first language. Content-based second language learning in a context such as a science classroom is considered advantageous as it enables the learner to manipulate a target language such as English in a way which is meaningful. However, science students who have yet to achieve communicative competence in English are disadvantaged when it comes to developing a deep understanding of scientific concepts. Many mainstream science teachers have concerns about this significant group of learners who can be left on the periphery of the class to cope as best as they can. Very often teachers aim to meet the needs of English Second Language (ESL) learners without any specific knowledge of the strategies which would enhance learning and ensure that learning environments encourage participation and interaction. The students themselves have not only to deal with language and sociocultural issues but must face the cognitive demands of science including negotiating its specialised language. / The study had two main purposes. The first goal was to describe the current situation with respect to nine ESL learners of science and their teachers in selected learning environments in Australia. The secondary purpose was to bring about improvement in the students' situations by employing specifically designed interventions. The study had three focal areas: the language; the teaching and learning environment; and the ESL student. It was conducted in three phases. Phase one involved investigating the current situations in the three focal areas. Phase two involved reflection, planning and development of the broad interventions and specific strategies which were used to assist teaching and learning. In phase three the strategies were implemented and their effectiveness was analysed using a multidimensional interpretive framework. Changes in communicative competence, interactional and participative competencies and academic competence were observed. The interventions which were intended to promote communicative competence for the language focus, involved integration of language and literacy instruction with science education. To improve participation and interaction in the teaching and learning environment, individual assistance was provided. In order to promote academic competence for the students, content, process and/or product modifications were made to science courses. / Data for the qualitative case studies was collected using classroom observation, teacher and student interviews, checklists of strategies and language errors, and portfolios of student work. Observations of the science classes in phase one revealed that, even for the students with very limited English language proficiency there was little ESL specialist support available. Mainstream subjects like science provided opportunities for language development, with biology lessons consistently including more activities which involved a combination of speaking, listening, reading and writing than did chemistry or physics classes. However, there was no coordinated approach to integrating language education with science education. The development of cognitive1 academic language took longer than 10 years for some of the students in the study. The non-technical language used in science lessons affected the students' understanding much more than the teachers were aware. Teachers' attitudes and beliefs strongly influenced the interaction and participation of ESL students in science classrooms. Developing language skills prevented ESL students asking and answering questions in class and academic progress in science was impeded by limited opportunities for ESL students to clarify their understanding. Achievement in science was affected by assessment instruments which were infused with specific linguistic or cultural knowledge. / After the introduction of the interventions, improvements in communicative competence occurred for all students with the greatest progression occurring in the students with less developed language skills. Interaction and participation improved markedly in the science classrooms where teachers provided individual assistance to students. Academic competence increased in all cases. The most promising approaches included: addressing the specific language needs in a particular unit of work; the development of customized materials; the provision of weekly tutorials; and the revision of assignment drafts.

In 1987, as a matter of utmost urgency and importance, Negara Brunei Darussalam called for a new system of education that emphasized nationalistic commitment: “Languages for Bruneians”. With the era of globalization, the Brunei Ministry of education argued that new patterns of communication were necessary and implemented a bilingual policy where children are taught in Malay until the fourth year of primary school when the medium of instruction changes to English. While the new policy supports Bruneians’ proficiency in two languages, rumour has been magnified through recent established research findings that a large percentage of pupils are underachieving in science. The main focus of this study is the effect of language transfer, from Malay to English as the medium of instruction, on the development of children’s conceptual understanding in science. Two clusters of science concepts, evaporation and condensation and living and non-living, provide the science context through which children’s understanding is explored. The theoretical framework that includes viewing and examining children’s conceptual understanding from conceptual development and epistemological and ontological perspectives of conceptual change informs the analysis of this study. The research design employed a cross sectional case study method involving the administration of interviews to a total of 255 children aged between 6 and 12 years of age. The interviews about the concepts of evaporation and condensation involved two phases. For the first phase, 60 children from each primary level of 1, 3 and 4 (total n = 180) were interviewed. Fourteen months later, 18 children from the same sample were selected based on their fluency in the first interviews and revisited for more detailed interviews. / For the concepts of living and non-living, 75 children were chosen from a wider range of primary levels, fifteen from each level of Primary 1, 3, 4, 5 and 6. Each participant in this study was asked 2 types of questions; forced-response and semi-structured. For the forced-response questions, scores were entered into the Statistical Packages for Social Sciences (SPSS) computer software based on a 5- point scale. For the semi-structured questions, analysis involved initial grouping of responses before entry into the software and quantitative manipulation. The data from the semi-structured interviews also were analysed qualitatively with systematic searches for themes and evidence that supported and disconfirmed the quantitative results. As this study produced qualitative as well as quantitative data, rigour was determined by two sets of parallel criteria. Ensuring rigour for the quantitative data involved the criteria of validity and reliability. Within the qualitative paradigm, the criteria that evolved in response to the quality of the research were credibility, transferability, dependability and confirmability. The results indicated a steady progress of conceptual understanding when the pupils’ explanations about the concepts of evaporation and condensation were in Malay. However, the pattern of development of understanding did not reach projected patterns i n Primary 4 when only English responses were analysed. The findings show that the change in language of instruction significantly hampered communication about and possibly conceptual understanding of the cluster of concepts associated with evaporation and condensation. / Similarly, the findings about children’s conceptual understanding of living and non-living suggested that the expected patterns of development were not realised. Closer qualitative inspection of the data revealed that the idiosyncratic nature of the bilingual system perpetuated particular misconceptions specifically related to the nature of the Malay and English languages in both clusters of concepts. The primary conclusion of the study was that the change in language of instruction from Malay to English in Brunei primary schools had a significant, detrimental impact on the children’s expressed understanding of the concepts associated with evaporation and condensation and living and non-living.

<p> High school students in the United States for the past century have typically taken science courses in a sequence of biology followed by chemistry and concluding with physics. An alternative sequence, typically referred to as &ldquo;physics first&rdquo; inverts the traditional sequence by having students begin with physics and end with biology. Proponents of physics first cite advances in biological sciences that have dramatically changed the nature of high school biology and the potential benefit to student learning in math that would accompany taking an algebra-based physics course in the early years of high school to support changing the sequence. Using a quasi-experimental, quantitative research design, the purpose of this study was to investigate the impact of science course sequencing on student achievement in math and science at a school district that offered both course sequences. The Texas state end-of-course exams in biology, chemistry, physics, algebra I and geometry were used as the instruments measuring student achievement in math and science at the end of each academic year. Various statistical models were used to analyze these achievement data. The conclusion was, for students in this study, the sequence in which students took biology, chemistry, and physics had little or no impact on performance on the end-of-course assessments in each of these courses. Additionally there was only a minimal effect found with respect to math performance, leading to the conclusion that neither the traditional or &ldquo;physics first&rdquo; science course sequence presented an advantage for student achievement in math or science.</p>

<p> Committed elementary teachers of science and engineering, members of a professional learning community called Collaborative Conversations in STEM, were studied to elicit their perceptions of experiences that influenced their commitment to, and their pedagogical content knowledge of, STEM teaching and learning. The hermeneutic phenomenological interviews enabled the teachers to express their beliefs in their own words. Data analysis employed a theoretical framework that investigated teacher epistemology and knowledge in light of their experiences. Findings revealed a web of lifelong experiences unique to each individual, and evidential of the committed elementary scientist-teachers&rsquo; present day values, teaching epistemology, lifelong learning, and emotional and intellectual engagement. Scientist-teachers are individuals whose teaching and learning characteristics reflect those of scientists and engineers.</p><p> Evidence indicated that no single transformative learning experience resulted in those elementary teachers&rsquo; commitment to STEM teaching and learning, but recent professional development activities were influential. Formal K-16 STEM learning was not uniformly or positively influential to the teachers&rsquo; commitment to, or knowledge of, STEM.</p><p> Findings suggest that ongoing professional development for STEM teaching and learning can influence elementary teachers to become committed to actively teaching STEM. The Collaborative Conversations in STEM provided intellectual and emotional engagement that empowered the teachers to provide STEM teaching and learning for their students and their colleagues overcoming impediments encountered in a literacy-focused curriculum. Elementary teachers actively committed to teaching science and engineering can undergo further transformation and emerge as leaders.</p>
