Introductory biology courses are frequently offered separately to biology majors and nonbiology majors, with the assumption that the two groups of students are different enough to merit different courses. To assess the evidence behind this assumption, we compared students in two different genetics classes at the University of Colorado–Boulder, one class for nonscience majors (nonmajors) and the other class for biology majors and students planning a biology-related career (majors), to see whether these two groups of students were fundamentally different in performance and attitudes. To measure content knowledge, we administered identical assessments to both groups of students during the semester: a validated pre- and postcontent assessment (Genetics Concept Assessment), ungraded quizzes after problem-solving sessions, and questions on each exam. We measured attitudes, study time, and study techniques through online surveys. Majors outperformed nonmajors on content assessments, finishing with significantly higher learning gains. Nonmajors and majors also differed in their motivation, interest, study time, and expert-level of beliefs. We suggest that focusing on the process of science and its connection to students'' lives will better engage and motivate nonmajors while still helping them learn the fundamental concepts of genetics. 相似文献

We have developed and validated a tool for assessing understanding of a selection of fundamental concepts and basic knowledge in undergraduate introductory molecular and cell biology, focusing on areas in which students often have misconceptions. This multiple-choice Introductory Molecular and Cell Biology Assessment (IMCA) instrument is designed for use as a pre- and posttest to measure student learning gains. To develop the assessment, we first worked with faculty to create a set of learning goals that targeted important concepts in the field and seemed likely to be emphasized by most instructors teaching these subjects. We interviewed students using open-ended questions to identify commonly held misconceptions, formulated multiple-choice questions that included these ideas as distracters, and reinterviewed students to establish validity of the instrument. The assessment was then evaluated by 25 biology experts and modified based on their suggestions. The complete revised assessment was administered to more than 1300 students at three institutions. Analysis of statistical parameters including item difficulty, item discrimination, and reliability provides evidence that the IMCA is a valid and reliable instrument with several potential uses in gauging student learning of key concepts in molecular and cell biology. 相似文献

Secondary teachers participating in summer professional development chemistry workshops in Texas used an online chemistry
tutoring program, OWL Quick Prep (Day et al. in OWL: Online Web-based Learning, Brooks-Cole Cengage Learning, Florence, KY,
1997) as a part of the inservice training. Self-reported demographic data were used to identify factors in preparation and practice
that affected pretest and posttest scores. Data from the pretests and posttests indicate that nomenclature and problems requiring
calculations were the most challenging topics for the cohort. The participants who correctly completed 90% of the questions
in the tutoring modules showed significant improvement in content mastery. 相似文献

This study of classroom discourse and other data from a physical science course for in-service teachers show the areas of
success and challenge of the participants in making claims supported by justifications. It also shows that the teachers learned
to make scientific claims and were able to make some justifications. Nevertheless, many found the process difficult. Some
of those who performed well in the course did not consider the pedagogy suitable for their own students. The implications
of the findings for elementary teacher education are discussed. 相似文献

Previous literature has demonstrated that networks can be valuable sources of professional learning. In 2005 all Liverpool
schools formed into ten Learning Networks with the aim of improving the quality, and entitlement of, continuing professional
development (CPD) for staff as part of a whole-scale local authority initiative. The Liverpool Learning Networks Research
explored professionals’ CPD experiences following this organizational change and whether it has enhanced their practice. Triangulated
data, a large-scale survey and qualitative interviews conducted in 2007, seem to suggest that where professionals benefited
from professional learning in a networked context, the quality of the networked CPD as well as a positive school culture and
intra-school collaboration were all important contributors to the success of networked-CPD. This finding can usefully apply
Turbill’s (Teacher learning for educational change. Open University Press, Buckingham, 94–114, 2002) model of professional learning to the intersection between school-based and networked-CPD, which suggests that it is at
this intersection between internal and external domains that teacher learning can take place. Two scenarios, where this interplay
between school-based and networked CPD is positive (enhancement) or negative (tension), are reported through five case studies
of professionals underpinned by the survey data, where relevant. 相似文献

Whilst an academic working in the arts may have been appointed as a consequence of artistic accomplishment and a capacity to teach, the research that underpins such work is an intrinsic part of its production and also needs to be recognised. In Australia, the ability of the artist‐academic to translate research into a form that is respected and rewarded is an issue of contention. This paper gathers responses to this issue. Perceptions of and attitudes to creative work as research are canvassed alongside life decisions arising from those perceptions and attitudes. This research occurs in the context of a new Australian framework for the evaluation of research. This framework offers some recognition of the research that supports creative practice. Thus, the long‐standing experience of compromise reported by the Australian artist‐academics interviewed for this study are discussed alongside new policies that seek to construct methodologies for its amelioration. 相似文献

Student’s learning is the result of a large number of interactions in all areas. Consequently, with an increasing number of intercultural students, we need to bring to the classrooms successful educational actions that enhance interactions and that have an impact on improving education. Based on the CONEXITO project, this article shows how interactive groups (IGs) have contributed to increase not only the educational success of native students but also the success of immigrant students in different schools of Spain, for which IGs have particular educational outcomes. The communicative qualitative data presents evidence that, especially focusing on them, IGs increase instrumental learning and facilitate the bonds of solidarity and mutual help. 相似文献

This paper compares French- and English-language Canadian television coverage of Australian Aboriginal athlete Cathy Freeman during the 2000 Olympics using a narrative framework. The specific focus of the analysis is the representation of Freeman's political identity as an agent and symbol of Aboriginal reconciliation – the struggle for apology, reparatio, and social justice in the light of the history and legacy of colonial oppression and exclusion. Freeman has used her sporting success to signify visibly and with some controversy her identification with political Aboriginality and reconciliation, and she went into the 2000 games bearing an unusual weight of expectation, intensified by being chosen to light the Olympic cauldron, that a victory in the 400 metres would mark symbolically reconciliation between Aboriginal and non-Aboriginal Australians. The analysis generally conforms the hypothesis that the normative dimension of these expectations would be accentuated more in the French- than English-language coverage, and this resulted in a more consistently affirmative portrayal of Freeman and her performance. The English-language coverage emphasized the ambivalent nature of her role. The corollary of this was that the English-language coverage paid greater attention to the substance of Aboriginal grievances and struggle. Nonetheless, neither network saw Freeman's identity in openly critical terms: in Freeman's Olympic narrative sport and politics were allowed to mix in a relatively unproblematic way. 相似文献

Because several studies have investigated student outcomes in schools implementing Response to Intervention (RtI), relatively little research has investigated the impact of implementation on students’ long‐term achievement outcomes (i.e., several years after exposure). The purpose of this study was to describe one elementary school's RtI implementation process and to examine students’ long‐term reading comprehension outcomes following their exposure to various phases of implementation. Four cohorts of students who experienced different implementation phases (i.e., a baseline condition or Phases I, II, or III of implementation) during Grade 2 were subsequently followed across Grades 3, 4, and 5 to examine their outcomes on two reading comprehension measures. Results indicated that students who experienced the early phases of RtI implementation (i.e., Phases I and II) during Grade 2 generally had higher mean comprehension scores in Grades 4 and 5 than students in the baseline condition. Implications for practice and future research are discussed. 相似文献
