The development of three-dimensional learning among all K-12 student demographics remains a prominent goal for the field of science education. However, substantial research in science teacher education for urban populations showcases hurdles to overcome in order to achieve this goal, particularly for elementary teachers. Research shows that urban elementary teachers are often ill-prepared to develop a type of science pedagogy responsive to students' learning needs. The fidelity of such pedagogies that these teachers adhere to when trying to implement such a requested content–relationality between these populations and how their local contexts can be used as sites to learn science in relevant ways are often not fully realized, as well. Given that science achievement gaps exhibit racial disparities starting in primary grades and attitudes toward science have been shown to affect academic achievement and motivation, we argue that one way to ameliorate, in at least an incremental way, this disparity is to design novel learning experiences to prime students to see the relevancy of science in their local contexts before such three-dimensional designed learning is set to occur. In this research, we leveraged the immersive nature of Virtual Reality 360 videos and present a design-based research iteration testing how this novel technologically enhanced learning experience may have influenced close to 400 urban elementary students' attitudes toward science around those attitudes labeled as “behavioral beliefs” by the field. Using a concurrent, convergent mixed-methods design with a two-way multivariate analysis of covariance quantitative data set triangulated with students' qualitative self-reports that were transformed into quantitative preponderances in graphic form, the data support that our design iteration emphasizing the importance of context as a design focus can prime students who struggle to see science as relevant to change their attitudes. Implications are discussed around relationality, novel technological affordances, and the use of local contexts as learning resources.  相似文献

The ability to read relies upon not just decoding, but also comprehending text. Being a good comprehender requires strategic reading and implies the use of comprehension strategies. Research indicates that readers who are taught several reading comprehension strategies have better reading skills than those only taught a single strategy. One multiple strategy reading comprehension intervention was evaluated using a mixed-model quasi-experimental design. Intervention and control conditions groups were assessed at pre- and post-test points with standardised reading comprehension abilities, measured as the primary outcome measure. Implementation science principles were observed and evaluated. The schools all served areas of low socio-economic status. 74 pupils (aged 9–10) in five classes in four primary-level mainstream schools in a Scottish local authority were recruited as participants. Training was provided to participating schools by the first author and the programme was delivered in four sessions of 45 minutes per week for 8 weeks. An ANCOVA revealed a statistically significant effect of condition. Statistically significant scores were also evident in the secondary outcome measures of decoding of target word skills, children’s self-reports of their reading strategy use and recreational reading frequency. Implementation tools indicated that the intervention was acceptable and feasible to implement. Implications of introducing this multiple strategy reading comprehension programme and of the evaluation of implementation are discussed.  相似文献

Massive Online Open Courses (MOOCs) provide opportunities to learn a vast range of subjects. Because MOOCs are open to anyone with computer access and rarely have prerequisite requirements, the range of student backgrounds can be far more varied than in conventional classroom-based courses. Prior studies have shown that misconceptions have a huge impact on students' learning performance; however, no study has empirically examined the relationship between misconceptions and learning persistence. This study of 12,913 MOOC-takers examines how students' misconceptions about the upcoming course material affect course completion. Using a survival analysis approach, we found that, controlling for the score in a pre-course test, students holding more misconceptions had a higher dropout rate at the start of the course, an effect that diminished over time. Other student variables were found to have a positive impact on survival that persisted throughout the entire course: U.S. location, higher age, an intention to complete, better English skills, prior familiarity with the subject, motivation to earn a certificate, and score and time spent on the previous problem set (homework). By contrast, student gender, education level, number of previous MOOCs completed, and motivation to participate in online discussion forums did not affect survival.  相似文献

Much has been studied regarding university reforms and their impacts on scientific development worldwide. This paper aims to enrich current perspectives on university reform by developing a distinct concept of social science development in the context of the emergence of academic social sciences in Indonesia. Using a bibliometric method, this paper finds a significant increase in the volume of international scientific publications focusing on socio-economic and political issues. However, two issues that presently color the landscape of social scientific publications are the bifurcation of academic dependencies and limited extension of Western social theories. The future of the social sciences in Indonesia will be determined by interrelationships between the state, universities, and networks of academics who can address the former issue and ensure that academics publish in mainstream international journals emphasizing the prominence of the latter. In doing so, the social sciences will have the potential to improve future university teaching and engagement in public policymaking in Indonesia.  相似文献

Recruiting and preparing STEM majors for teaching has become one of the major efforts at improving mathematics and science teacher quality at secondary level. One question is whether STEM majors who have not had the chance to experience active learning in mathematics and science classes as secondary students themselves know what inquiry pedagogy is. Secondly, it is unclear whether those who experienced inquiry in their college introductory discipline courses will be able to utilize the pedagogy in teaching secondary content. We address these questions through studying an undergraduate research methods course designed to improve STEM majors’ capacity for delivering inquiry-based mathematics and science lesson. Analysis of data from pre-and-post course surveys and students’ written research reports including students’ reflection on their inquiry projects suggests that offering future STEM teachers opportunities to conduct inquiry and reflect explicitly on how inquiry can be used to teach secondary content is important and beneficial.  相似文献

Student exchange programs and trips abroad are consistently portrayed in scholarship as a strategy for promoting students’ global competence. Through a thematic document analysis of a mandatory course developed by the Israeli MOE for students embarking on trips abroad and additional sources, I explore the discourse used to portray these trips in the Israeli context, showing an alternative model that places the state rather than students at the center of these programs. Although from an education perspective this discourse is distinct, political science scholarship suggests the goals it embodies could be embedded across many national contexts, albeit more discretely.  相似文献

The Next Generation Science Standards (NGSS) strives to shift science learning from the teacher as a single cognitive agent, to a classroom community in which participants are working together in directing the classroom's communal knowledge to figure out questions about how phenomena occur, and building, testing, and refining their ideas to address those questions. To achieve this type of classroom environment, teachers should attend to students' knowledge and ideas and pay attention to how students are located within teacher-led interactions, such as being positioned as active discussants or designated listeners. In this study, we explore if and how this is occurring in the NGSS era. We used a naturalistic inquiry to explore how an experienced first-grade teacher used a new NGSS-aligned unit that called for students to use the science and engineering practices (SEP) to build content knowledge. We used a macro-analytic lens to answer the research question “how are class discussions shaped to address the SEP”? We used a micro-analytic lens to answer the research question “how are students positioned during these science discussions in this classroom?” Evidence suggests that the teachers' whole class discussions incorporated and involved the SEP which were specified in the unit lessons for content learning. However, on a micro-analytic level, we found that few students were positioned as active discussants. The teacher heavily relied on those students who could provide succinct and clearly relevant answers while positioning the remainder of the students as silent spectators. Implications from this research suggest that not only new NGSS curriculum materials need to focus on what students should know and do but they also need to address heuristics for teachers that show them how to position all of their students as active doers of science so all students have opportunities to build deeper, core science knowledge.  相似文献
