Abstract: Food science laboratory courses are traditionally taught as a series of preplanned laboratories with known endpoints. In contrast, inquiry‐guided (IG) laboratories allow students to ask questions, think through problems, design experiments, then adapt and learn in response to unexpected results. This study examined the effects of converting the course, “Analytical Techniques in Food and Bioprocessing Sciences” from a traditional approach (2008 to 2010 data) to an IG approach (2011 data) by assigning teams of 2–3 students a food and a set of 5 analyses to conduct over the course of the semester. Students were required to choose and justify the use of specific methods for each analysis, as well as to develop a supply list and a budget for the semester‐long project. During the semester, students were required to post and discuss their weekly progress with the instructor, teaching assistants, and the rest of the class using an online discussion forum. At the end of the semester, students were required to present the results of their analysis in both oral and written formats. Overall course grades were significantly higher (P≤ 0.05) using IG in 2011 compared to 2010 and 2009, but not to 2008 grades. Numerical course evaluations for the instructor, overall course, and lab, as well as written course evaluations all significantly (P≤ 0.05) improved. This suggests that an IG approach may measurably improve student performance in terms of course grades and the ability to complete semester long projects. It may also increase student satisfaction with the course, as measured by numerical and written end of semester surveys.  相似文献   

Bioinformatics Education in High School: Implications for Promoting Science,Technology, Engineering,and Mathematics Careers

We investigated the effects of our Bio-ITEST teacher professional development model and bioinformatics curricula on cognitive traits (awareness, engagement, self-efficacy, and relevance) in high school teachers and students that are known to accompany a developing interest in science, technology, engineering, and mathematics (STEM) careers. The program included best practices in adult education and diverse resources to empower teachers to integrate STEM career information into their classrooms. The introductory unit, Using Bioinformatics: Genetic Testing, uses bioinformatics to teach basic concepts in genetics and molecular biology, and the advanced unit, Using Bioinformatics: Genetic Research, utilizes bioinformatics to study evolution and support student research with DNA barcoding. Pre–post surveys demonstrated significant growth (n = 24) among teachers in their preparation to teach the curricula and infuse career awareness into their classes, and these gains were sustained through the end of the academic year. Introductory unit students (n = 289) showed significant gains in awareness, relevance, and self-efficacy. While these students did not show significant gains in engagement, advanced unit students (n = 41) showed gains in all four cognitive areas. Lessons learned during Bio-ITEST are explored in the context of recommendations for other programs that wish to increase student interest in STEM careers.  相似文献   

Some values to the broadcaster of election campaign broadcasting     

Richard D. Porter 《广播与电子媒介杂志》2013,57(2):145-156

A great deal has been said about the value of political broadcasting to the public and to the politician. However, very little has been written about its effect upon the broadcaster. The following study was performed in an effort to arrive at some understanding of what monetary, public relations, and other values election campaign broadcasts have to the broadcast station manager or licensee.  相似文献   

The constitutive force of the Catecismo del Pueblo in Puerto Rico's popular democratic party campaign of 1938–1940     

Nathaniel I. Cordova 《Quarterly Journal of Speech》2013,99(2):212-233

This paper explores the formation of a political order, a constituency, during the 1938–1940 senatorial campaign of the Partido Popular Democratico in Puerto Rico. In particular it examines the constitutive force of the Catecismo del Pueblo, a small booklet in the form of questions and answers regarding the party's basic assumptions and orientations. This booklet developed a political constituency by mediating a covenantal relationship through discourse in the form of a catechism. Burke's notion of constitutional dialectics is used to explore the Catecismo's nature as constitutive, as a catechism, and as the mediator of a political covenant between the Party and the jíbaros.  相似文献

State Perspectives on Implementing,or Choosing Not to Implement,an Alternate Assessment Based on Modified Academic Achievement Standards     

Porter W. Palmer 《Peabody Journal of Education》2013,88(4):578-584

Since Federal regulations have given states the option to implement alternate assessments based on modified academic achievement standards (AA-MAS) as part of their accountability systems for a small group of students with disabilities, a number of states have made decisions about whether or not to develop and implement such an assessment. State-level directors of assessment and directors of special education were surveyed about their state's decisions on implementing AA-MAS. Improvements in accessibility and appropriateness were reasons given for choosing to implement an AA-MAS, whereas lack of resources and guidance were identified as barriers. This article presents the findings from a survey on 22 states' decisions concerning implementation of AA-MAS.  相似文献   

Migrating from ILLiad to Tipasa     

Toccara D. Porter 《Journal Of Access Services》2020,17(2):83-95

Abstract

Tennessee State University was a decade long user of OCLC’s ILLiad platform. 2019 marked the year when the relationship with that system ended as our two interlibrary loan departments migrated to Tipasa, OCLC’s new cloud-based system. The platform change did not stem from dissatisfaction with ILLiad but from being informed that Tipasa would eventually replace ILLiad. This article covers three areas of the implementation: communication, staff training, and outreach. Explained is the communication had between library staff and OCLC representatives, what our participation in online cohort training involved, and included are visuals used to inform our campus about Tipasa.  相似文献

Is Procrastination Related to Low-Quality Data?     

Nathaniel M. Voss  Lisa Vangsness 《Educational Measurement》2020,39(4):95-104

While it is easy to assume that university students who wait until the last minute to complete surveys for their class research requirements provide low-quality data, this issue has not been empirically examined. The goal of the present study was to examine the relation between student research procrastination and two important data quality issues—careless responding and measurement noninvariance. Data gathered from university students across two semesters tentatively indicated that procrastination is related to low-quality survey data. Procrastination was slightly more problematic for certain data quality issues (measurement noninvariance) than others (careless responding). These relations, however, were small and contingent on how procrastination and careless responding were measured. Accordingly, it seems more beneficial for researchers to select a sampling window that supports their research goals and statistical power requirements rather than select a sampling window that attempts to minimize careless survey responding or other measurement issues.  相似文献
