Bakgrund: Statistik visar på ökat antal elektiva kejsarsnitt internationellt och nationellt. Ett kejsarsnitt kan rädda liv på mor och barn om komplikationer uppstår, elektivt kejsarsnitt är även liksom andra stora operationer förenat med risker för komplikationer. Antalet elektiva kejsarsnitt på humanitär indikation har ökat i Sverige och cirka 17 % av alla förlossningar sker via kejsarsnitt. Att vårda och stödja kvinnor före, under och efter en förlossning med kejsarsnitt hör till barnmorskans arbete. Syftet med studien var att beskriva barnmorskors uppfattning om indikationer och effekter av förlossning med elektiva kejsarsnitt på humanitär indikation belyst utifrån arbetslivserfarenheter. Metod: kvalitativ metod: semistrukturella intervjuer med nio barnmorskor. Materialet analyserades via fenomenografisk analys i sju steg. Resultat: Fyra beskrivningskategorier framkom, Elektivt kejsarsnitt på humanitär indikation är ett etiskt dilemma, Elektivt kejsarsnitt på humanitär indikation är en stor operation, Elektivt kejsarsnitt på humanitär indikation påverkar organisation och barnmorskans arbetsmiljö och Elektivt kejsarsnitt på humanitär indikation påverkar kvinnans förlossningsupplevelse. Vidare framkom nio kategorier som beskriver barnmorskors uppfattningar. Slutsats Barnmorskor uppfattar elektiva kejsarsnitt som något komplext, att de med sina yrkeskunskaper värnar det naturliga vid kejsarsnitt på humanitär indikation och att de har brist på mandat att stödja och stärka kvinnors informerade val om elektivt kejsarsnitt på humanitär indikation. Klinisk tillämpbarhet: Resultatet kan användas vid undervisning kring barnmorskans stödjande och vårdande arbete i samband med förlossning via kejsarsnitt. Vidare kan resultatet vara underlag till diskussioner inom mödrahälsovård och förlossning i syfte att ge barnmorskor stärkt mandat till sina stödjande och informativa uppgifter. / Background: Statistics show an increased number of elective caesarean section internationally and nationally. A caesarean section can save the life of mother and child if complications arise, elective caesarean section in common with other major surgeries involve risk of complications. The number of elective caesarean sections on humanitarian indication has increased in Sweden and about 17% of all deliveries via caesarean section. To care and support women before, during and after a cesarean is an essential part of midwifery work. Objective: The aim of the study is to describe midwives' perception of indications and effects of childbirth by elective caesarean section on humanitarian indication illuminated on the basis of work experience. Method: A qualitative approach: semi structural interviews with nine midwives, phenomenographic analysis in seven steps was used for analysis of data. Results: Four descriptive categories emerged, elective Caesarean section on humanitarian indication is an ethical dilemma, elective Caesarean section on humanitarian indication is major surgery, elective Caesarean section on humanitarian indication affect the organization and midwives working environment and elective Caesarean section on humanitarian indication affect the woman's birth experience. Further nine categories that describe midwive´s perceptions emerged. Conclusion: Midwives perceived elective ceaserean section as something complex, that with their professional skills they support the natural part in caesarean sections on humanitarian indication and they lacked mandate to support and strengthen women's informed choice regarding elective Caesarean section on humanitarian indication. Clinical applicability: The result can be used in education regarding midwives supportive and caring role in deliveries with caesarean section. In addition the result can be used in discussions at delivery wards and antenatal care units regarding improving midwives mandate for their supportive and informative tasks.

This study is a systematic literature review on the role of models and representations in the teaching, learning and understanding of the atom and atomic concepts. The aim of the study is to investigate the role of different visual representations, what models and representations are used in the science classroom, how learners interpret different external representations of the atom, what mental models students construct, and how the representations can be used and designed for meaningful learning and teaching of the atom and atomic concepts.   In this systematic literature review, a combination of different databases was used to search for literature, namely ERIC, Scopus and Google Scholar. Some limiters were used to narrow down the returned results: the articles should be peer-reviewed and be published 1990-01-01 or later. Ten of the returned articles were included for individual analysis in the study.   The results of the study show that students often find concepts of atomic structure difficult and confusing. The abstract microscopic world of atoms cannot be seen with the naked eye, and models are therefore necessary and crucial educational tools for teaching atomic concepts in school. However, when using a model, it is important for the teacher to explain the rules of the model, and the advantages and limitations of the representation must be discussed. Analysis of the included articles revealed three types of representations used to represent atomic phenomena: two-dimensional static diagrams or pictures (e.g. a picture of the atom), three-dimensional videos or simulations (e.g. virtual reality simulations), and visual analogies (e.g. the Bohr planetary model of the atom). The use of simulations and interactive learning environments seem to have a positive effect on students’ learning. One of the studies, described in the articles included for analysis, showed that students appreciated the use of virtual reality simulations, since it made abstract concepts easier to understand when they could be visualized.

Constructivist learning theory is based upon the tenets that students come to learning experiences with prior knowledge and experiences that the learner will choose from to make sense of the present situation. This leads to a mixture of understandings among students. This study proposed to reveal students‟ understanding of atomic structure and cell structure as well as the relationships between atoms and cells. High school students from one private school participated in a paper-and-pencil test to uncover conceptual understanding and content knowledge of atoms and cells. The 120 participants were from grades: 9 (13m, 15f), 10 (9m, 20f), 11 (21m, 17f), and 12 (17m, 8f). All 120 students took the paper-and-pencil test and 16 students (4 per grade) participated in a follow-up interview. Drawings were analyzed by individual characteristics then using groups of characteristics models classes were formed. Openended questions were scored holistically by rubric scores and then deconstructed into individual content statements. A limited number of findings follow. Students were more likely to draw a Bohr model. Freshmen were less likely to indicate living materials contained atoms and more likely to indicate forms of energy contained atoms. As students progressed through high school, details included in cells decreased. Students failed to recognize that the sum of the products from cell division will be larger than the original cell due to the two growth periods included in the division cycle. Students were often able to provide the correct yes or no answer to are atoms and cells similar, different, or related but the follow-up answers often included non-scientific conceptions. Recommendations include implementing instructional strategies that promote long-term retention of conceptual understanding and the underlying content knowledge. Design evaluation methods to monitor student understanding throughout a unit of study that go beyond traditional closed-ended questions. Many limitations related to this study suggest that results should not be generalized beyond the targeted population.

<p>The information and communication technology, ICT, is opening new possibilities for the educational arena. Previous research shows that achieving positive educational outcomes requires more than simply providing access to computer hardware and software. How does this new technology affect the teaching and learning of physics? This thesis focuses on the field of geometrical optics. It reports two studies, both in Swedish upper secondary school. Important for the use of the ICT in physics education is the teaching strategy for using the new technology. The first study investigates with a questionnaire, how 37 teachers in a region of Sweden use computers in physics education and what intentions they follow while doing so. The results of this study show that teachers’ intentions for using ICT in their physics teaching were to increase students' interest for physics, to increase their motivation, to achieve variation in teaching, and to improve visualization and explanation of the phenomena of physics. The second study investigates students’ conceptual change in geometrical optics during a teaching sequence with computer-assisted instruction. For this purpose we choose the computer software "Constructing Physics Understanding (CPU)", which was developed with a base in research on students conceptions in optics. The thesis presents the teaching sequence developed together with the teacher. The study is based on a constructivist view of learning. The concepts analysed in this study were vision, image, ray and image formation. A first result of this study is a category system for conceptions around these concepts, found among the students. With these categories we found that students even at this level, of upper secondary school, have constructed well-known alternative conceptions before teaching, e.g. about a holistic conception of image. The results show also some learning progress: some alternative conceptions vanish, in some cases the physics conceptions are more often constructed after teaching. The students and the teacher also report that the CPU program gave new and useful opportunities to model multiple rays and to model vision.</p>

Increased state and federal accountability measures have made the assessment of student performance one of the most critical responsibilities of classroom teachers; yet, inadequate opportunities for preservice and inservice training leave many teachers feeling ill-prepared for this task. Adding to the complexity of building teachers’ assessment literacy is the relationship between assessment beliefs and classroom assessment practices. This quantitative study utilizes a validated, online survey to examine how elementary teachers’ (n = 79) define their assessment beliefs (conceptions) and how these beliefs influence which assessment practices are valued within the classroom. Findings suggest that despite teachers’ limited exposure to assessment training, four distinct assessment beliefs exist within the elementary classroom: assessment for school accountability, assessment for student certification, assessment for improvement of teaching and learning, and assessment as irrelevant. Assessment for the improvement of teaching and learning yielded the highest composite mean and was negatively correlated with the irrelevance belief and positively related to school accountability. An analysis of the importance of assessment practices revealed authentic assessments, short answers, teacher-made assessments, and performance assessments as the most valued, while publisher assessments and major exams had the lowest means. Significant relationships were identified between demographics and beliefs and practices, with the most practical findings related to exposure to assessment training and level of degree attainment. Significant relationships were also noted between all beliefs and the value of specific assessment practices, with the exception of the irrelevance belief. No significant relationships were noted between the irrelevant belief and value of assessment practices; however, many negative correlations were documented. Results are discussed in light of other research, indicating that a greater understanding of assessment beliefs and importance of practices can contribute to the development of relevant professional development aimed at the improvement of teachers’ assessment pedagogies and practices can contribute to greater educational success.

Denna studie hade som syfte att undersöka olika individers föreställningar och uppfattningar om terrorism. För att undersöka detta ämne har semistrukturerade intervjuer genomförts med sex olika individer. Studiens första huvudresultat och även den viktigaste slutsatsen var att olika individer har olika uppfattning om vad terrorism är och hur det ska definieras, men att den gemensamma idén är att målet eller syftet är det som avgör om det rör sig om terrorism. De flesta intervjupersonerna ansåg att både fysiskt och psykiskt skadade människor kan vara offer för terrorism. Huvudresultatet gällande terrorister handlade om föreställningar kring terroristers utseende, till exempel “stort skägg” och “muslimer”. Vad gäller medias framställning av terrorism upplevde de flesta intervjupersoner att media vinklar och utelämnar information, samt har en viss påverkan på deras uppfattning om terrorism. Intervjupersonerna nämnde också en ökad rädsla och oro för terrorism, något som dock inte påverkade deras vardagliga rutiner och handlingar. / This study has exanimated different individuals’ conceptions and perceptions of terrorism. To examine this issue we have done semi-structured interviews with six different individuals. The first main result of the study and the most important conclusion was that different individuals had different perceptions about what terrorism is and how it should be defined. Most of the interviewees counted both physically and psychologically harmed people as victims of terrorism. The main result when it comes to conceptions about terrorists looks was that terrorists have “big beard” and were “Muslims”. When it comes to medias representation of terrorism most of the interviewees believed that media angle and leave out information, and that this had some influence on their perception of terrorism. The interviewees also mentioned an increased fear and concern about terrorism, something that did not affect their daily routines and activities.

Orientador: Elianeth Dias Kanthack Hernandes / Resumo: A leitura constitui prática reconhecidamente valorizada no âmbito da sociedade, uma vez que sua utilização remete a maior possibilidade de participação em diferentes esferas sociais. Portanto, saber ler vai muito além de saber a pronúncia das letras e a decodificação de sílabas. Por sua função social, o domínio das capacidades de leitura é uma questão de cidadania, pois possibilita a capacidade criadora e o posicionamento crítico diante da complexidade do mundo no qual estamos inseridos. Outro ponto de destaque para a pesquisa que originou este trabalho é o entendimento de que a escola é a agência por excelência de veiculação e produção desses conhecimentos. Sendo assim, ela desempenha um papel de extrema importância no processo de aquisição da leitura, e deve sempre buscar o desenvolvimento leitor de seus alunos, de forma plena, por intermédio das tematizações das práticas sociais de leitura e escrita proporcionadas no contexto escolar. Nesta perspectiva, este estudo está centrado no tema da formação de alunos leitores e das práticas de professores alfabetizadores que são destinadas a esta formação. O ensino da leitura, por muitas décadas, foi baseado em métodos caracterizados pelo progresso passo a passo, ou seja, decorava-se o alfabeto, soletrava-se, decodificavam-se palavras isoladas, frases e por fim textos. O estudo partiu do pressuposto que este é um caminho que se distancia das concepções sobre o ensino da leitura defendidas por autores: Ferreiro e Teberosky (1999), S...

Therefore, knowing how to read goes far beyond knowing the pronunciation of letters and the decoding of syllables. Due to its social function, the mastery of reading skills is a matter of citizenship, since it enables the creative capacity and critical positioning in the face of the complexity of the world in which we are inserted. Another highlight of the research that originated this work is the understanding that the school is the agency par excellence for conveying and producing this knowledge. Therefore, it plays an extremely important role in the process of acquisition of reading, and should always seek the reader development of its students, fully, through the themes of social practices of reading and writing provided in the school context. From this perspective, this study is centred on the subject of the training of student readers and the practices of literacy teachers that are intended for this training. The teaching of reading, for many decades, was based on methods characterised by step-by-step progress, i.e. decorating the alphabet, spelling, decoding individual words, sentences and finally texts. The study was based on the assumption that this is a path that distances itself from the conceptions about the teaching of reading advocated by authors: Ferreiro and Teberosky (1999), Smith (2003), Cadermatori (2006), Freire (2011)...

L’évolution du vivant est un concept majeur pour les sciences biologiques contemporaines, mais également un objet d’enseignement complexe. En France, l'évolution du vivant est introduit dès l’école primaire. Cet enseignement ne devient explicite qu’en fin de la scolarité obligatoire. Cette étude vise à mieux comprendre comment les conceptions de collégiens français sur l’évolution du vivant se modifient tout au long du collège et comment leurs conceptions du hasard peuvent influencer leur acceptation et leur compréhension de ce concept. Pour cela, un questionnaire, UnRESt est élaboré et permet d’étudier les conceptions de plus de 1600 collégiens de l'évolution du vivant et du hasard, et d’établir les relations éventuelles entre ces deux types de conceptions. Il est construit sur la base des résultats obtenus dans des études exploratoires (questionnaire ouvert, discussion à visée philosophique). L’étude révèle que, quel que soit le niveau de classe, la moitié des collégiens interrogés acceptent l’évolution du vivant, et un tiers d’entre eux semblent avoir une compréhension en désaccord avec une pensée évolutionniste. Selon les espèces étudiées, une vision explicative 'transformiste' subsiste chez les élèves. L’étude révèle également que l’acceptation et la compréhension de l’évolution du vivant sont en lien avec les conceptions du hasard. En particulier, les résultats témoignent d’un obstacle dans l’utilisation du mot hasard au sens de contingence, ainsi qu’une influence de leur vision du hasard ‘probabliste’ sur leur compréhension des mécanismes d’évolution. Cette recherche appelle à laisser une place plus importante au hasard dans l’enseignement au collège. / Evolution of living species is a major concept for the contemporary biological sciences, but also a complex object of teaching. In France, the evolution of living species starts in primary school. This teaching becomes well identified only at the end of compulsory schooling. This study aims a better understanding on the change of the conceptions of secondary school students along junior high school and how their conceptions of randomness can influence their acceptation and their understunding of this concept. Consequently, a questionnaire, UnRESt has been elaborated to study the mainstream conceptions of more than 1600 students about the evolution of living and randomness and to find potential links between these two types of conceptions. The UnRESt ingineering is based on exploratory studies (open-ended questions, philosophical discussion). The study shows that a half of the students accept the evolution of living species and a third of them seems to have an understanding in opposition with an evolutionist understanding. According to the species studied, a ‘transformist’ vision is favoured by student. They highlights also that the acceptation and the understanding of the evolution are related to the students’ conceptions of randomness. More specifically, the results show an obstacle in the use of the word randomness with the meaning of contingency and an influence of their vision of ‘probabilist’ randomness on their understanding of the evolution mechanisms. The research concludes on the place to give to the scientific concept of randomness in the teaching in secondary school.

<p>In Colombia, as in the US, higher education institutions are charged with the twofold responsibility of training well-rounded professionals and pushing the boundaries of knowledge. Faculty enact this dual responsibility through their teaching and research duties, among other job-related functions. Also like in the US, research has increasingly become the foremost function of faculty at most prominent Colombian universities. As the emphasis on research increased, teaching became regarded as a simpler activity that requires less effort and resources. Moreover, while discussions about the importance of quality teaching and the need to better train faculty to enact their teaching function are common, promotion and rewards systems at Colombian universities fail to reflect a real commitment to quality teaching. Research has taken precedence over teaching, and often is perceived as the only scholarly function of faculty. While this continued perception cannot be attributed to a single reason, I hypothesize that how faculty conceive of their teaching role impacts our ability to make a compelling case for the scholarly nature of teaching.</p> <p> </p> <p>Testing this hypothesis requires a systematic approach to exploring faculty’s conceptions of teaching within a context. To that aim, I pose this research question: What are conceptions of teaching held by Colombian engineering faculty interested in improving their teaching? I advance a framework for exploring conceptions of teaching drawing from Bandura’s Social Cognitive Theory and previous scholarly works on faculty’s conceptions and beliefs about teaching. Drawing upon this framework, I explore the beliefs, practices, and contextual factors of Colombian engineering faculty at three institutions. While these faculty members differ in terms of their disciplinary backgrounds, teaching experience, and research activity—both disciplinary and educational, they all share an interest in improving their teaching practice. This exploration first takes an analytic approach to identify the pieces that constitute participants’ conceptions of teaching, and then knits those pieces together to look at participants as wholes.</p> <p><br></p><p>The literature on conceptions of teaching has usually classified them between traditional teacher-centered to more sophisticated student-centered views. However, I believe that there is a continuum worth exploring defined by these extreme views. In fact, I argue that there are multiple continua—or dimensions—that merit exploration. Such dimensions include perceptions about the role of teachers, the role of students, the nature of knowledge, the purpose and means of assessment, and the outcomes of education—previously explored in the relevant literature—and views of the interaction between college teaching and research—a dimension distinctive of the present study. My findings suggest that while the role of the teacher and of students, and the nature of knowledge can be described by the teacher- to student-center and knowledge-transmission to knowledge-construction continua, the latter three dimensions are better described along different scales. Moreover, while there are certain correlations between these dimensions (e.g., perceptions of the role of the teacher as a guide correlate with perceptions of a more active role of the students) none of them alone can accurately describe the nuances of an individual’s conception of teaching. </p> <p> </p> <p>Conceptions of teaching uncovered and characterized in this multidimensional way can inform professional development programs that go beyond the diffusion of pedagogical innovations to a perspective transformation among participants. Specifically, my findings corroborate that changes in faculty views of assessment toward more formative stances foster positive transformations in faculty’s overall conception of their teaching role and duties. My findings also suggest that faculty members intrinsically interested in improving their teaching constitute the seed to start educational reform. Community-building efforts to bring together these faculty should, in the long term, help transform the views of academic administrators, thus fostering lasting reform in the perception and recognition of teaching as a scholarly function of faculty.</p>

This exploratory, descriptive and interpretive study investigated the interactions among learners’ conceptions of the nature of scientific inquiry (NOSI), teachers’ conceptions of NOSI and teacher instructional practices when teaching investigations in Physical Science. The participants were South Africa, Grade 11 learners (n= 167) and teachers (n=5), from five schools in the Johannesburg region of South Africa. The schools were conveniently and purposefully sampled. Learners’ and teachers’ conceptions on six NOSI tenets were investigated. These tenets are: difference between laws and theories; difference between observation and interpretation; there is no one method in science; accurate record keeping, peer review and replicability in science; socially and culturally embeddedness nature of scientific knowledge; and the role of human creativity and imagination in the development of scientific knowledge. Data on learners’ and teachers’ conceptions of the NOSI was obtained through; questionnaires, probes and interviews. Teacher instructional practices were determined using laboratory class observations, questionnaires, teacher and learner interviews, and analysis of instructional materials. The data was quantitatively analyzed using mainly, descriptive statistics, correlations, Regression Analysis and Multivariate Analysis of Variance (MANOVA). Qualitative data was analyzed using a combination of analytic induction and interpretive analysis. The results show that learners’ NOSI conceptions were inconsistent, fragmented and fluid, with the majority of the learners displaying naïve conceptions. Teachers were found to hold mixed NOSI conceptions ranging from static, empiricist-aligned to dynamic, constructivist-oriented. Teacher instructional practices were found to be a repertoire of contrasting methodological approaches lying along a continuum ranging from close-ended inquiry to open-ended inquiry. The study found the interactions between and among the investigated variables to be weak and not direct and simple, but complex and under the governance of a variety of factors in the instructional milieu. Curriculum and assessment demands were found to be major factors possibly responsible for weakening the interactions. For the investigated variables, it is posited that the interaction between variables is under the governance of both the context in which the instruction takes place and some factors already embedded in the teacher’s or learner’s conceptual ecology. Recommendations and implications for the practice of science education and future research are raised and discussed.
