College-level biology courses contain many complex processes that are often taught and learned as detailed narratives. These processes can be better understood by perceiving them as dynamic systems that are governed by common fundamental principles. Conservation of matter is such a principle, and thus tracing matter is an essential step in learning to reason about biological processes. We present here multiple-choice questions that measure students' ability and inclination to trace matter through photosynthesis and cellular respiration. Data associated with each question come from students in a large undergraduate biology course that was undergoing a shift in instructional strategy toward making fundamental principles (such as tracing matter) a central theme. We also present findings from interviews with students in the course. Our data indicate that 1) many students are not using tracing matter as a tool to reason about biological processes, 2) students have particular difficulties tracing matter between systems and have a persistent tendency to interconvert matter and energy, and 3) instructional changes seem to be effective in promoting application of the tracing matter principle. Using these items as diagnostic tools allows instructors to be proactive in addressing students' misconceptions and ineffective reasoning.  相似文献

Objectives:

Through interviews with the National Library of Medicine''s MedlinePlus Go Local collaborators, an evaluation team sought to identify process characteristics that are critical for long-term sustainability of Go Local projects and to describe the impact that Go Local projects have on sponsoring institutions.

Methods:

Go Local project coordinators (n = 44) at 31 sponsor institutions participated in semi-structured interviews about their experiences developing and maintaining Go Local sites. Interviews were summarized, checked for accuracy by the participating librarians, and analyzed using a general inductive methodology.

Results:

Institutional factors that support Go Local projects were identified through the interviews, as well as strategies for staffing and partnerships with external organizations. Positive outcomes for sponsoring institutions also were identified.

Conclusions:

The findings may influence the National Library of Medicine team''s decisions about improvements to its Go Local system and the support it provides to sponsoring institutions. The findings may benefit current sponsoring institutions as well as those considering or planning a Go Local project.

Highlights

  • Many project coordinators said they underestimated the level of work their National Library of Medicine (NLM) MedlinePlus Go Local projects would require, but most expressed dedication to the project and optimism about project sustainability.
  • An institutional record of community service or outreach and a director who was supportive of the project were important factors in the progress and sustainability of Go Local projects.
  • Go Local projects brought recognition to some sponsoring institutions from their parent institutions or their communities and provided opportunities to establish better relations with other libraries and institutions.
  • Go Local projects ran more smoothly when a person, even a temporary hire, with dedicated time for the project was in charge during the initial building phase. Volunteer assistance has been difficult to motivate and sustain.

Implications

  • NLM''s Go Local proposal guidelines accurately identify the factors that institutions should pay close attention to when planning a Go Local project.
  • NLM should emphasize continuity plans to address project coordinator turnover.
  • NLM should develop a more formal orientation plan for new project coordinators to assist program continuity at the sponsoring institutions.

In this study the learning process of 12 Dutch novice university teachers was monitored during a five-month induction programme. The teachers were interviewed before and after the programme and were asked to fill in several email logbooks during the programme. A change process was identified, in which experiencing and experimentation played a central role. In particular, modelling by the teacher educator, the observation of video cases, reflection on these with peers and experiencing success in their own practice seemed to be important incentives that encouraged teachers to adopt and eventually implement new pedagogical approaches. On the basis of our data, we think that teachers' conceptions and teaching practice are best developed simultaneously and that the design of induction programmes should support this process.  相似文献
