Concept inventories, consisting of multiple-choice questions designed around common student misconceptions, are designed to reveal student thinking. However, students often have complex, heterogeneous ideas about scientific concepts. Constructed-response assessments, in which students must create their own answer, may better reveal students' thinking, but are time- and resource-intensive to evaluate. This report describes the initial meeting of a National Science Foundation-funded cross-institutional collaboration of interdisciplinary science, technology, engineering, and mathematics (STEM) education researchers interested in exploring the use of automated text analysis to evaluate constructed-response assessments. Participants at the meeting shared existing work on lexical analysis and concept inventories, participated in technology demonstrations and workshops, and discussed research goals. We are seeking interested collaborators to join our research community.  相似文献

Classroom instructional quality,exposure to mathematics instruction and mathematics achievement in fifth grade

This study examined the quality of teacher–child interactions and exposure to mathematics instruction as predictors of 5th grade student’s mathematics achievement. The sample was a subset of the children involved in the NICHD–SECC longitudinal study (N = 657). Results indicate that, even after controlling for student demographic characteristics, more exposure to mathematics instruction was related to increased fifth grade mathematics achievement for both calculations and applied problems assessments, but there was no main effect for improved instructional quality. Findings also indicate that, in classrooms where lower instructional quality was observed, greater exposure to mathematics instruction predicted improved mathematics achievement. Findings are discussed in terms of differing aspects of mathematics instruction and the possible compensatory role of exposure to instruction in classrooms of lower quality.  相似文献

The Project Ownership Survey: Measuring Differences in Scientific Inquiry Experiences     

David I. Hanauer  Erin L. Dolan 《CBE life sciences education》2014,13(1):149-158

A growing body of research documents the positive outcomes of research experiences for undergraduates, including increased persistence in science. Study of undergraduate lab learning experiences has demonstrated that the design of the experience influences the extent to which students report ownership of the project and that project ownership is one of the psychosocial factors involved in student retention in the sciences. To date, methods for measuring project ownership have not been suitable for the collection of larger data sets. The current study aims to rectify this by developing, presenting, and evaluating a new instrument for measuring project ownership. Eighteen scaled items were generated based on prior research and theory related to project ownership and combined with 30 items shown to measure respondents’ emotions about an experience, resulting in the Project Ownership survey (POS). The POS was analyzed to determine its dimensionality, reliability, and validity. The POS had a coefficient alpha of 0.92 and thus has high internal consistency. Known-groups validity was analyzed through the ability of the instrument to differentiate between students who studied in traditional versus research-based laboratory courses. The POS scales as differentiated between the groups and findings paralleled previous results in relation to the characteristics of project ownership.  相似文献   

Implementing web 2.0 tools in the classroom: Four teachers’ accounts     

Cindy Kovalik  Chia-Ling Kuo  Megan Cummins  Erin Dipzinski  Paula Joseph  Stephanie Laskey 《TechTrends》2014,58(5):90-94

In this paper, four teachers shared their experiences using the following free Web 2.0 tools with their students: Jing, Wix, Google Sites, and Blogger. The teachers found that students reacted positively to lessons in which these tools were used, and also noted improvements they could make when using them in the future.  相似文献

An Experimental Test of Medical Disclosure and Consent Documentation: Assessing Patient Comprehension,Self-Efficacy,and Uncertainty     

Erin E. Donovan  Brittani Crook  Laura E. Brown  Angie E. Pastorek  Camille A. Hall  Michael S. Mackert 《Communication monographs》2014,81(2):239-260

Effectively conveying risks and hazards in medical disclosure and informed consent documentation is a crucial type of communication. However, existing protocols typically do not meet the needs of patients or practitioners. In the present study, we advance a reconceptualization of obtaining written informed consent by analyzing it as a process of uncertainty management rather than a matter of document readability and recall. Results of this randomized trial indicated that patients who reviewed a simplified consent document reported greater comprehension of medico-legal terminology and lower uncertainty about the document, although they did not evince greater self-efficacy. Health literacy was a significant moderator of the relationship between consent form version and comprehension.  相似文献   

The Scientific Manpower Shortage and Its Implications for the Engineering Technician     

Merrill  John 《Education, IRE Transactions on》1960,3(1):3-10

Some of the background of the present scientific manpower shortage is reviewed. Utilization as an important aspect of engineer efficiency is discussed. With this setting, the engineering technician's complementary function with the engineer is introduced. The limited availability of technicians is cited. A discussion of the stepping-stone aspect of the technician job, an area worth consideration because of its ramifications, is presented and the concept of a four-year program for engineering technicians is shown to have significant value in coping with several phases of technician training. Four areas of study and investigation are suggested that can contribute to solution of the overall need of increased scientific manpower through increased utilization. Utilization would be improved by the proper preparation of an adequate number of engineering technicians.  相似文献
