An interdisciplinary team set out to integrate teaching approaches to address this trend. The objective of this project was to develop a web-based teaching tool, which combined a face-to-face problem-based learning (PBL) case study with multimedia to illustrate the impacts of three land-uses on soil transformation and quality. The Land Use Impacts (LUI) tool (http://soilweb.landfood.ubc.ca/luitool/; verified 4 Oct. 2011) was a collaborative and concentrated effort to maximize the advantages of two educational approaches—the web's adaptability and accessibility, and PBL's capability to foster an authentic learning environment, apply core concepts, and encourage group work. The design of the LUI case study was guided by Herrington's development principles for web-based authentic learning. The LUI tool presented students with rich multimedia (streaming videos, text, data, photographs, maps, and weblinks) and real world tasks (site assessment and soil analysis) to encourage students to utilize knowledge of soil science in collaborative problem-solving. Preliminary student feedback indicated that the LUI tool conveyed case study objectives and was appealing to students. The tool is intended primarily for students enrolled in an upper level undergraduate/graduate university course titled Sustainable Soil Management, but it is flexible enough to be adopted for other natural resource courses.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":"40 1","pages":"215-223"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2010.0032n","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86056773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ementoring program was part of a career portfolio prepared in sections of AGRI 1201, Agriculture and Human Sciences as a Profession, that were major specific for animal science majors. Impact of the experience on students was evaluated with pre- and post-mentoring questionnaires using Likert-scale (1–5, 1 = disagree or low level), selection (check those that apply), and open-ended questions. Pre-mentoring questionnaires (n = 128, 2002-2005) showed a willingness to participate in the ementoring program; however, students were reluctant to relocate for career reasons. Results revealed naivete about careers, limited career awareness and work experience. A total of 79 post-mentoring questionnaires were submitted from 2002 to 2005. Post-mentoring results indicated gains in career awareness (means of 3.84–4.23 across years) and that gains were related to the ementor (means of 3.33–4.00). Interest in career exploration also increased (means of 3.67–4.39) as did willingness to relocate for career purposes (mean of 3.64–4.15). The ementoring experience was perceived as a beneficial experience that included problem solving (38–64%), goal identification (33–67%), and career insight (44–72%). From 77 to 88% of students wanted to continue email communication with their ementor after the course-related requirement was completed.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":"40 1","pages":"150-159"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2010.0020u","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74139710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objectives of this manuscript were to develop simple and inexpensive methodologies to both qualitatively and quantitatively estimate water infiltration rates (IR), water-holding capacity at saturation (WHCs), and potential nitrate-nitrogen (NO3–N) loss and to test the accuracy and precision of these methods. Complete details for how to assemble the appropriate supplies and conduct the measurements are provided, but for demonstrative purposes these methods do not need to be followed in detail, particularly using the various equations to get quantitative values. In the field and classroom, these demonstrations have been well received by non-technical and technical audiences and have been performed by request as well as incorporated into agronomy classes for high school and college students and training for agriculture educators. In the laboratory, these methods were tested on 10 benchmark soils and values were compared with each other and soil aggregation as measured by dry soil aggregate distribution and water stability. In these benchmark soils, IR and WHCs increased with a reduction in soil disturbance and more continuous plant cover due to diverse crop rotation and perennials while NO3–N loss was highest in soils with synthetic fertilizer inputs, little plant cover, and more soil disturbance. These results indicate the methodologies outlined here may be used to demonstrate agroecosystem management's impact on soil health.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":"40 1","pages":"51-57"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2009.0033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78343383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an effort to reverse this trend, the Agronomy Department at Iowa State University (ISU) launched the I'm An Agrono- mist marketing campaign in 2006. This article reports on these efforts and the change in the undergraduate agronomy student population at Iowa State University since the campaign's inception. In the spring of 2010, 106 more students were studying agronomy than in 2005. This was an increase of 91%. Prior to implementing marketing strategies, agronomy enrollment at ISU had been on a 6-year decline. The campaign has also had the additional benefits of generating a sense of pride and excitement among department staff, students, and alumni. The execution of the marketing campaign has been accomplished through close collaboration between staff within our department including graphic artists, communication specialists, and those passionate about the topic. In designing our marketing strategies, we observed and learned from marketing approaches in widespread use. The most important elements in the development of our marketing campaign were a simple message, artistic style, branding, and advertising in smart locations. While direct connections between marketing efforts and enrollment increases are difficult to prove, the I'm An Agronomist campaign has coincided with a time of extraordinary growth in student numbers. The campaign has also appeared to have had additional benefits with regard to internal morale and external relations.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":"40 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72295659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Excel is easy to use, powerful, and versatile, and it requires the least proficiency in computer programming compared to other programming platforms. Excel, however, has several weaknesses: it does not directly support loops for iterative calculations, and it does not allow one cell to alter the contents of another cell. Thus, the objective of this study was to develop an Excel add-in, called BuildIt, that overcomes some of Excel's weaknesses by: (1) providing a loop for repetitive calculations and (2) providing several operations (called actions) typically needed in building crop models. These actions are such as for numerical integration, initialization of variables, and solving differential equations using the Runge-Kutta method, as well as for copying and manipulation of cell ranges. BuildIt was written in Excel's script language, Visual Basic for Applications (VBA), but it does not require users to program in VBA to build their models. Several examples of models were used in this article to illustrate how BuildIt implements the infrastructure in Excel, and how it can be used to build models and run model simulations. With BuildIt, users are able to use Excel to build and run their mathematical models, without requiring any knowledge in VBA.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":"40 1","pages":"122-136"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2010.0024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85183259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
