This research examines how science teaching orientations and beliefs about technology-enhanced tools change over time in professional development (PD). The primary data sources for this study came from learning journals of 8 eighth grade science teachers at the beginning and conclusion of a year of PD. Based on the analysis completed, Information Transmission (IT) and Struggling with Standards-Based Reform (SSBR) profiles were found at the beginning of the PD, while SSBR and Standards-Based Reform (SBR) profiles were identified at the conclusion of PD. All profiles exhibited Vision I beliefs about the goals and purposes for science education, while only the SBR profile exhibited Vision II goals and purposes for science teaching. The IT profile demonstrated naïve or unrevealed beliefs about the nature of science, while the SSBR and SBR profiles had more sophisticated beliefs in this area. The IT profile was grounded in more teacher-centered beliefs about science teaching and learning as the other two profiles revealed more student-centered beliefs. While no beliefs about technology-enhanced tools were found for the IT profile, these were found for the other two profiles. Our findings suggest promising implications for (a) Roberts' Vision II as a central support for reform efforts, (b) situating technology-enhanced tools within the beliefs about science teaching and learning dimension of science teaching orientations, and (c) revealing how teacher orientations develop as a result of PD. 相似文献

The Faulkes Telescope Project and its educational aims are briefly summarised. Research to evaluate its impact in inspiring excitement and interest among students is described. The Faulkes Telescope in Hawaii was used to provide images for assessed coursework based on two of the Faulkes “education/research” projects on galaxies. Students’ attitudes to various aspects of using the telescope and to the two galaxy projects were obtained using a questionnaire and free‐response comments. The students were found to be enthusiastic about all aspects of the telescope and the idea of carrying out serious science investigations based on the images that they had obtained. 相似文献

The study presented in this paper integrates data from four combined research studies, which are both qualitative and quantitative in nature. The studies describe freshman science student teachers' beliefs about teaching and learning. These freshmen intend to become teachers in Germany in one of four science teaching domains (secondary biology, chemistry, and physics, respectively, as well as primary school science). The qualitative data from the first study are based on student teachers' drawings of themselves in teaching situations. It was formulated using Grounded Theory to test three scales: Beliefs about Classroom Organisation, Beliefs about Teaching Objectives, and Epistemological Beliefs. Three further quantitative studies give insight into student teachers' curricular beliefs, their beliefs about the nature of science itself, and about the student- and/or teacher-centredness of science teaching. This paper describes a design to integrate all these data within a mixed methods framework. The aim of the current study is to describe a broad, triangulated picture of freshman science student teachers' beliefs about teaching and learning within their respective science teaching domain. The study reveals clear tendencies between the sub-groups. The results suggest that freshman chemistry and—even more pronouncedly—freshman physics student teachers profess quite traditional beliefs about science teaching and learning. Biology and primary school student teachers express beliefs about their subjects which are more in line with modern educational theory. The mixed methods approach towards the student teachers' beliefs is reflected upon and implications for science education and science teacher education are discussed. 相似文献

Given the importance of explanation in science texts for children, this research explored Coh-Metrix as a tool for rapidly determining the presence of explanations in science trade books. Variables from Coh-Metrix specifically addressing cause (causal content, causal cohesion, and positive causal connectives) were correlated with an existing, high-inference causal variable from previous research. Moderate correlations were found for causal cohesion and positive causal connectives (both r(18) = 0.46, p < 0.05); no correlation was found with causal content. Somewhat stronger correlations were found with two, co-referential Coh-Metrix variables, argument overlap and stem overlap. These findings suggest that Coh-Metrix may be used for an initial screening to determine if a science text has the necessary conditions to be explanatory. 相似文献

In many Western societies, there is a concern about the tendency of young people not choosing Science, Technology, Engineering, and Mathematics (STEM) education and occupations. In response, different initiatives have been launched. If one believes that science should have a place in more young people's lives, an important question is to what extent recruitment campaigns communicate messages that open up for STEM education to become relevant in young people's identity formation. Here, we analyse a Swedish government-initiated, primarily Internet-based recruitment attempt (‘The Broad Line Campaign’) aimed at increasing the number of young people choosing the natural science programme in upper secondary school. The campaign is based on marketing principles and deliberately draws on identity issues. The data analysed consists of campaign films and written resources describing the campaign. Data are analysed by use of the constant comparative approach in order to produce categories describing different messages about why to engage in STEM education. These messages are then analysed from an identity perspective using the concept of subjective values. Our results show that the messages communicated in the Broad Line campaign emphasise utility value, attainment value and relative cost rather than interest-enjoyment. The campaign communicates that the natural science programme is to be associated with a high attainment value without establishing relations to the field of science. Finally, potential consequences of the communicated messages in the campaign are discussed in light of previous research. 相似文献

It is commonly argued that socio-economic inequalities can explain many of the differences in achievement and participation in science education that have been reported among countries and among schools within a country. We addressed this issue by examining (a) the relationship between variables associated with socio-economic background and application frequencies to the Swedish Natural Science Programme (NSP) in upper secondary school and (b) whether there are lower secondary schools in Sweden that seem to compensate for these variables. Data from Statistics Sweden (SCB) covering the whole population of 106,483 ninth-grade students were used to calculate the probability for each student to apply to the NSP. Our results indicate that the variables, such as parental educational level and grades, have explanatory power, but with varying effect for different subpopulations of students. For example, grades in mathematics have a greater impact than grades in science for females' choice of the NSP. The opposite holds for male students. Out of 1,342 schools, 158 deviated significantly from predicted, that is, the students in these schools applied to the NSP in greater or lesser extent than expected. The number of deviating schools is greater than predicted by pure random variation. This suggests that variables of socio-economic background are only a partial explanation of the application frequencies, and that the deviation needs to be investigated further. Our findings suggest that in order to understand why schools deviate positively and so compensate for the socio-economic background of their students, we need to study their practices more closely. 相似文献

ABSTRACTIn order to create conditions for students’ meaningful and rigorous intellectual engagement in science classrooms, it is critically important to help science teachers learn which strategies and approaches can be used best to develop students’ scientific literacy. Better understanding how science teachers’ instructional practices relate to student achievement can provide teachers with beneficial information about how to best engage their students in meaningful science learning. To address this need, this study examined the instructional practices that 99 secondary biology teachers used in their classrooms and employed regression to determine which instructional practices are predictive of students’ science achievement. Results revealed that the secondary science teachers who had well-managed classroom environments and who provided opportunities for their students to engage in student-directed investigation-related experiences were more likely to have increased student outcomes, as determined by teachers’ value-added measures. These findings suggest that attending to both generic and subject-specific aspects of science teachers’ instructional practice is important for understanding the underlying mechanisms that result in more effective science instruction in secondary classrooms. Implications about the use of these observational measures within teacher evaluation systems are discussed. 相似文献

Using data from 24 countries, which participated in the 2006 Programme for International Student Assessment (PISA), we examine the relationship between parental science employment and students' career expectations. In contrast to prior PISA-based studies, we find that the link between parental employment and adolescent plans to work in science is non-trivial and merits attention. In this context, we consider three versions of the gender socialisation hypothesis. The strong variant posits that girls' plans are shaped solely by their mothers' career pathways while boys model their expectations exclusively on fathers’ occupations. The weaker version of this hypothesis expects children to be influenced more by the same-sex than by the opposite-sex parent. Finally, the third possibility is that, as egalitarian ideologies prevail, parents inspire adolescent occupational plans regardless of gender. These hypotheses are assessed separately for student career plans related to biology, agriculture and health (BAH) in contrast to computing, engineering and mathematics (CEM), because the involvement in these fields of science is known to be segregated by gender. Using two-level multinomial logit modelling, we find some support for the weak version of the gender socialisation hypothesis. Although within-family transfers of preferences for science careers vary considerably across countries, we note certain regularities. In many nations, relevant paternal employment enhances sons' interest in science careers regardless of their field. In contrast, maternal employment inspires daughters in fewer countries and this influence tends to be limited to careers in BAH. We discuss the possible implications of these findings for science educators. 相似文献

ABSTRACTThis paper assesses the relationship between participation in two tertiary science courses and the science teaching efficacy beliefs (STEBs) of one cohort of preservice elementary teachers over a four-year period. Two Type II case studies were conducted within the courses. Data were collected through 26 administrations of the Science Teaching Efficacy Belief Instrument-B and semi structured interviews. Results showed that participation in the subjects covaried with increases in the participants’ STEBs. These increases in STEBs remained durable for two years. Implications for these findings are discussed within the paper. 相似文献
