Acquiring research skills is considered to be a highly challenging aspect of developing expertise in the social sciences.
Because instruction and mentoring in these skills are typically grounded in the self-report of researchers, difficulties in
learning the material may be due to the content and accuracy of these explanations. Using a mixed-method, microgenetic design,
this study examines the explanations of problem-solving processes by researchers along a continuum of expertise during simulated
experiment design and subsequent data analysis. Findings indicate that participants’ self-explanations are largely inaccurate.
Further, frequency of inaccurate statements is positively associated with the frequency of abstract cognitive processes, such
as mental modeling and situation assessment. Implications of these findings for instruction and future research directions
are discussed. 相似文献

Poor instruction has been cited as a primary cause of attrition from STEM majors and a major obstacle to learning for those who stay [Seymour and Hewitt [1997]. Talking about leaving: Why undergraduates leave the sciences. Boulder, CO: Westview]. Using a double‐blind design, this study tests the hypothesis that the lack of explicit instructions in scientific inquiry skills is a major factor in both low STEM retention and academic underperformance. This project delivered supplemental instruction to students in a laboratory‐based undergraduate biology course (n = 314) that was derived either from cognitive task analyses (CTAs) conducted with expert biologists (treatment) or was authored and delivered by an award‐winning biology instructor (control). Students receiving traditional instruction were almost six times more likely to withdraw from the course than students in the treatment condition (8.1% vs. 1.4% of initial enrollment). Of the students who completed the course, those who received the CTA‐based instruction demonstrated significantly higher levels of performance in the discussion section of their written laboratory reports. Significantly higher performances were seen specifically in the areas of analyzing data to formulate valid conclusions, considering alternative explanations, consideration for the limitations of the experimental design and implications of the research. © 2010 Wiley Periodicals, Inc.

Although learning to write for publication is an important outcome of doctoral education, it has received surprisingly little scholarly attention. Within a socialization and supervisor pedagogy framework, this study uses narratives of faculty who regularly write with their doctoral students for publication to expose challenges students commonly encounter in the writing process. Common challenges include international students' ‘writing problem’, misconstruing the nature of disciplinary writing and not realizing that ‘public’ is part of publication. 相似文献

ABSTRACTIn the biological sciences, very little is known about the mechanisms by which doctoral students acquire the skills they need to become independent scientists. In the postsecondary biology education literature, identification of specific skills and effective methods for helping students to acquire them are limited to undergraduate education. To establish a foundation from which to investigate the developmental trajectory of biologists’ research skills, it is necessary to identify those skills which are integral to doctoral study and distinct from skills acquired earlier in students’ educational pathways. In this context, the current study engages the framework of threshold concepts to identify candidate skills that are both obstacles and significant opportunities for developing proficiency in conducting research. Such threshold concepts are typically characterised as transformative, integrative, irreversible, and challenging. The results from interviews and focus groups with current and former doctoral students in cellular and molecular biology suggest two such threshold concepts relevant to their subfield: the first is an ability to effectively engage primary research literature from the biological sciences in a way that is critical without dismissing the value of its contributions. The second is the ability to conceptualise appropriate control conditions necessary to design and interpret the results of experiments in an efficient and effective manner for research in the biological sciences as a discipline. Implications for prioritising and sequencing graduate training experiences are discussed on the basis of the identified thresholds. 相似文献

Instruction on problem solving in particular domains typically relies on explanations from experts about their strategies.
However, research indicates that such self-reports often are incomplete or inaccurate (e.g., Chao & Salvendy, 1994; Cooke & Breedin, 1994). This article evaluates research on experts’ cognition, the accuracy of experts’ self-reports, and the efficacy of instruction
based on experts’ self-reports. Analysis of this evidence indicates that experts’ free recall of strategies introduces errors
and omissions into instructional materials that hinder student success. In contrast, when experts engage in structured knowledge
elicitation techniques (e.g., cognitive task analysis), the resultant instruction is more effective. Based on these findings,
the article provides a theoretical explanation of experts’ self-report errors and discusses implications for the continued
improvement of instructional design processes.

For some time, there has been a call for cross‐disciplinary teaching within the business disciplines. With the rise of data and analytics, there is an opportunity for cross‐disciplinary teaching by integrating technology throughout the business curriculum. However, many business professors have little experience in cross‐disciplinary teaching. We hope to rectify this by introducing an approach that uses prelecture material to prepare students for learning concepts and terms that are not core to the focal class. In a study that combines Structured Query Language (SQL) coding with an audit principle called Benford's Law, we analyze the impact of adding prelecture material about Benford's Law on student's cognitive load, knowledge gained, and instructional efficiency. Results indicate that students who received a prelecture on Benford's Law outperformed the control group in performance measures related to Benford's Law, and that the instructional efficiency on Benford's Law was also higher for the treatment group. We did not find any significant differences in cognitive load between the two groups, nor did the treatment group perform significantly better when tested on the SQL concepts. We conclude that cross‐discipline teaching is a fine balance between each discipline and communicating to students the importance of both disciplines is key. 相似文献

Most interventions with “maker” technologies take place outside of school or out of core area classrooms. However, intervening in schools holds potential for reaching much larger numbers of students and the opportunity to shift instructional dynamics in classrooms. This paper shares one such intervention where electronic textiles (sewable circuits) were introduced into eighth grade science classes with the intent of exploring possible gains in student learning and motivation, particularly for underrepresented minorities. Using a quasi-experimental design, four classes engaged in a traditional circuitry unit while the other four classes undertook a new e-textile unit. Overall, students in both groups demonstrated significant learning gains on standard test items without significant differences between conditions. Significant differences appeared between groups’ attitudes toward science after the units in ways that show increasing interest in science by students in the e-textile unit. In particular, they reported positive identity shifts pertaining to their perceptions of the beliefs of their friends, family, and teacher. Findings and prior research suggest that student-created e-textile designs provide opportunities for connections outside of the classroom with friends and family and may shift students’ perceptions of their teacher’s beliefs about them more positively. 相似文献
