DNA microarray wet lab simulation brings genomics into the high school curriculum     

Campbell AM  Zanta CA  Heyer LJ  Kittinger B  Gabric KM  Adler L  Schulz B 《CBE life sciences education》2006,5(4):332-339

We have developed a wet lab DNA microarray simulation as part of a complete DNA microarray module for high school students. The wet lab simulation has been field tested with high school students in Illinois and Maryland as well as in workshops with high school teachers from across the nation. Instead of using DNA, our simulation is based on pH indicators, which offer many ideal teaching characteristics. The simulation requires no specialized equipment, is very inexpensive, is very reliable, and takes very little preparation time. Student and teacher assessment data indicate the simulation is popular with both groups, and students show significant learning gains. We include many resources with this publication, including all prelab introductory materials (e.g., a paper microarray activity), the student handouts, teachers notes, and pre- and postassessment tools. We did not test the simulation on other student populations, but based on teacher feedback, the simulation also may fit well in community college and in introductory and nonmajors' college biology curricula.  相似文献   

Involving peers in the evaluation and improvement of teaching: A menu of strategies   总被引：1，自引：0，他引：1  

Kathleen M. Quinlan 《Innovative Higher Education》1996,20(4):299-307

Various approaches to conducting peer coaching and peer review are described in this article. Examples of team mentoring, reciprocal class visitation, teaching circles, departmental teaching libraries, teaching portfolios, course portfolios, pedagogical colloquia and departmental reviews are discussed as methods for involving peers in the evaluation and improvement of teaching. Many departments will adapt a combination of approaches which fit their particular goals and context. All of these approaches rest on the assumption of faculty responsibility for the process; grassroots leadership; and a view of teaching as a substantive, scholarly activity.Kathleen M. Quinlan is a doctoral candidate in the Stanford University School of Education. A former research assistant with the American Association for Higher Education' s Teaching Initiative, she is now an American Association of University Women Dissertation Fellow. After she completes her Ph.D. in June 1996, she will continue to pursue her interests in disciplinary and departmental cultures and peer involvement in teaching improvement and evaluation as a lecturer at the Centre for Academic Development and Educational Methods at the Australian National University, Canberra, Australia.  相似文献

The development of a science process assessment for fourth-grade students     

Kathleen A. Smith  Paul W. Welliver 《科学教学研究杂志》1990,27(8):727-738

In this study, a multiple-choice test entitled the Science Process Assessment was developed to measure the science process skills of students in grade four. Based on the Recommended Science Competency Continuum for Grades K to 6 for Pennsylvania Schools, this instrument measured the skills of (1) observing, (2) classifying, (3) inferring, (4) predicting, (5) measuring, (6) communicating, (7) using space/time relations, (8) defining operationally, (9) formulating hypotheses, (10) experimenting, (11) recognizing variables, (12) interpreting data, and (13) formulating models. To prepare the instrument, classroom teachers and science educators were invited to participate in two science education workshops designed to develop an item bank of test questions applicable to measuring process skill learning. Participants formed “writing teams” and generated 65 test items representing the 13 process skills. After a comprehensive group critique of each item, 61 items were identified for inclusion into the Science Process Assessment item bank. To establish content validity, the item bank was submitted to a select panel of science educators for the purpose of judging item acceptability. This analysis yielded 55 acceptable test items and produced the Science Process Assessment, Pilot 1. Pilot 1 was administered to 184 fourth-grade students. Students were given a copy of the test booklet; teachers read each test aloud to the students. Upon completion of this first administration, data from the item analysis yielded a reliability coefficient of 0.73. Subsequently, 40 test items were identified for the Science Process Assessment, Pilot 2. Using the test-retest method, the Science Process Assessment, Pilot 2 (Test 1 and Test 2) was administered to 113 fourth-grade students. Reliability coefficients of 0.80 and 0.82, respectively, were ascertained. The correlation between Test 1 and Test 2 was 0.77. The results of this study indicate that (1) the Science Process Assessment, Pilot 2, is a valid and reliable instrument applicable to measuring the science process skills of students in grade four, (2) using educational workshops as a means of developing item banks of test questions is viable and productive in the test development process, and (3) involving classroom teachers and science educators in the test development process is educationally efficient and effective.  相似文献   

Academic attitudes toward new media: An exploratory multidisciplinary study     

Kathleen Menzies  Frances Johnson 《The Information Society》2016,32(1):1-13

This article looks at the attitudes of UK academics toward new media, utilizing organizational and sociocultural understandings of fields of scholarly enquiry. It focuses on four traditionally distinct disciplines—art and design, computer science, health science, and politics and international relations—representative of the range of approaches in higher education. Agreement was found among respondents across disciplinary communities about what new media represent and how they support their work. Analysis of semantic differential charts identified two dimensions underlying attitudes—“flexibility” and “fitness for scholarly purposes.” Rather than being anchored by epistemological divisions, new media are assessed by practical viewpoints relating to the activity types they allow, and by traditional measures of reliability. In response to questions about other characteristics of their disciplines (such as reputation and audience diversity), distinctions are in evidence, although in some cases these are not traditional ones.  相似文献

Heroes of resiliency and reciprocity: teachers’ supporting role for reconceptualizing superhero play in early childhood settings     

Kathleen I. Harris 《Pastoral Care in Education》2016,34(4):202-217

Superhero play is a specialised form of fantasy play with considerable appeal to young children. During superhero play, children have opportunities to pretend and often to play different types of roles within a safe and caring environment. When guided appropriately in an early childhood classroom, superhero play gives young children opportunities to gain a sense of mastery and empowerment as well as developmentally appropriate benefits by improving language skills, problem-solving and cooperation with peers. By recognising and modelling the characteristics of resiliency and promoting kindness with peers during superhero play, teachers can encourage children to be kind and resilient heroes to classroom friends. As today’s classrooms increasingly include diverse members, it is important for young children to understand and appreciate the peers they play and learn with at school. The result may be a richer learning experience and may break down barriers that can produce unfairness, bullying and aggressive behaviours. This article explores the essence of superhero fantasy play along with its benefits for young children. In addition, the article examines the challenge of superhero play in classrooms for early childhood educators by exploring teachers’ roles in play. A new pedagogy for supporting superhero play is introduced, addressing spiritual and educational concerns by suggesting ways in which teachers can increase resiliency, encourage new friendships and build classroom community among peers during play and classroom activities.  相似文献
