Integration of inquiry-based approaches into curriculum is transforming the way science is taught and studied in undergraduate classrooms. Incorporating quantitative reasoning and mathematical skills into authentic biology undergraduate research projects has been shown to benefit students in developing various skills necessary for future scientists and to attract students to science, technology, engineering, and mathematics disciplines. While large-scale data analysis became an essential part of modern biological research, students have few opportunities to engage in analysis of large biological data sets. RNA-seq analysis, a tool that allows precise measurement of the level of gene expression for all genes in a genome, revolutionized molecular biology and provides ample opportunities for engaging students in authentic research. We developed, implemented, and assessed a series of authentic research laboratory exercises incorporating a large data RNA-seq analysis into an introductory undergraduate classroom. Our laboratory series is focused on analyzing gene expression changes in response to abiotic stress in maize seedlings; however, it could be easily adapted to the analysis of any other biological system with available RNA-seq data. Objective and subjective assessment of student learning demonstrated gains in understanding important biological concepts and in skills related to the process of science. 相似文献

The Republic of Belarus is a bilingual country, its two principal languages being Belarussian and Russian. Knowledge of other languages is encouraged; indeed, a specialized higher education institution, the Minsk State Linguistic University, has been created to prepare multilingual specialists in various fields. In addition, several non-state higher education institutions have developed bi- and multilingual partnerships with Western higher education institutions. 相似文献

This study involved an adaptation and evaluation of the Munich differential diagnostic instrument for the identification of gifted and highly gifted schoolchildren (KFT). An analysis was carried out of the relationship between various forms of giftedness and actual performance. A two step procedure was applied to select gifted students using a Teachers' Checklist, the KFT and tests of creativity. About 70 gifted youngsters were selected from 600 students. The label “gifted” was used for the top 6%‐10%, “highly gifted” for the top 3%–5% and “extremely gifted” for the highest scoring members of the group. The control group (70 unselected students) was investigated with the same methods. There were clear differences between the gifted, highly gifted and extremely gifted students in every domain of giftedness. Different forms of giftedness developed in the students during the three year period. 相似文献

The family is the main network of relationships in which the values and norms for living in society are transmitted. In a society where the presence of the media is prominent, media literacy in the family is more important than ever. For this reason, this study aims to analyse Spanish families’ perception of all aspects related to their knowledge about the media, their use of the media, their critical and expressive capacity and their perception of the weaknesses and risks of the media. To do so, we have analysed data from nine Spanish regions through focus groups (FG) with the participation of parents representing different kinds of families. The evidence collected highlights the need for media training for all family members so they can actively, critically and creatively take advantage of the potential afforded by the technologies and media in education for active, participatory citizenship. 相似文献

Arizona is one of six states leading the nation in English language learner (ELL) student enrollments and requiring all teachers to complete coursework in methods of teaching ELLs. This policy requirement has impacted teacher preparation programs and the field of teacher education as a whole. As such, there is a growing need to identify and evaluate factors that contribute to ELL teacher readiness. This exploratory survey study examines teacher readiness to work with ELLs in comprehensive public high schools in Arizona. This study was conducted using a survey instrument administered to in-service teachers (n?=?444). Correlation analyses indicate that there is a strong association between preservice preparation, preservice exposure to ELLs, and the feeling of readiness to serve ELLs. The findings make a strong case for further examination of preservice teacher preparation programs, in-service professional development, and their relationship to teacher readiness. 相似文献

The relationship between the different mediational means for supporting students’ learning with digital tools in science group work in a Norwegian lower-secondary school is examined. Analyses of teacher-student and student-student interactions are located in cultural-historical theory and draw on Galperin’s conceptualisation of learning processes. Findings show that digital tools, task design, peer collaboration, and teacher’s interventions dialectically interplay to shape how learners use mediational means: (1) digital tools are the resources that enable students to explicate their (mis)understandings; (2) compare-and-contrast tasks promote analytical thinking; (3) peers present themselves as resources who promote development of conceptual understanding; (4) the teacher guides learners’ attention towards the potential of the mediational resources, elicits, organises, and structures students’ knowledge. The dialectical interplay of these mediational means creates a system that supports and guides students’ learning. 相似文献

Peter I’s editorial policy appears as a starting point in the birth of secular Russian textbooks. Since the printing production was then organized on a massive scale as a response to the needs of European-like modernization, it should be safely suggested that nearly all books produced during this pioneering period focused teaching objectives. To understand how and why such an impressive cultural blossoming could occur, we must study their history as part of the broad process of the transfer of knowledge that interfered in all the domains of Russian life. As the textbooks were essentially the product of translation, the paper will explore four main points: Who were the translators? What and why did they translate? How did they proceed? What were their main problems and achievements? 相似文献

Professional development (PD) has been identified as a critical mechanism that helps teachers increase students' achievement. However, the content and form of this mechanism varies widely. This study examines an ongoing PD for school teachers, which has been explicitly founded on a set of guiding principles associated with quality professional development. The effects of participation in this program on three domains of teacher effectiveness, measured through classroom observations, are tested in a sample of 153 teachers. The domains of teacher effectiveness are planning and preparation, classroom environment, and instruction. Regression results indicate that participation in this program is significantly related to teachers' scores on instruction only. The implications of this finding indicate that high-quality professional development does not always address all domains of teaching. Other implications derived from the findings point to the need for professional development opportunities to be ongoing and highly focused on improving inquiry-based instruction. 相似文献

This article focuses upon programs for undergraduate women in science and engineering, which are a strategic research site
in the study of gender, science, and higher education. The design involves both quantitative and qualitative approaches, linking
theory, method, questions, and analyses in ways not undertaken previously. Using a comprehensive, quantitative, cross-institutional,
and longitudinal method, two extreme groups of programs are distinguished: those associated with the “most successful” and
“least successful” outcomes in undergraduate degrees awarded to women in science and engineering. Qualitative analyses of
interview data with key players in the programs in these two groups point to ways in which definitions of issues, problems,
and solutions diverge (as well as converge), and thus to conceptual underpinnings that have important real-life consequences
in these organizational settings of higher education. The programs that regard issues, problems, and solutions of women in
science and engineering as rooted in “institutional/structural-centered,” as opposed to “individual/student-centered,” perspectives
are associated with the most positive outcomes in undergraduate degrees awarded to women in science and engineering.
