Using a descriptive and correlational research design, data were collected from 588 middle school students (grades 6, 7, and 8). Participants completed a pretest and a posttest questionnaire on their attitude and interest in science. Findings showed that participants overall had a positive attitude toward and a positive interest in science; neither the attitude nor the interest changed from pretest to posttest. Within grade, attitude toward science fell slightly during 6th grade but rose slightly during 8th grade. There were no differences in pretest or posttest scores by gender. Prior research suggests that during middle school, students’ attitudes toward science and interest in science drop. An implication exists that the graduate student fellowship program had a positive influence on middle school students’ attitudes and interests in science by maintaining a high interest in science and a positive attitude toward science.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2011.0021k","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91435242","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}

Preparing students ahead of time for a week-long field trip to a new area that involves student-centered learning and a competition to promote student engagement should offer educational advantages. This article presents the results of a poll of teachers who coached students during a week-long soil judging contest field trip. The perspective on learning effectiveness is often asked of students rather than teachers. Five questions were asked and representative answers presented and discussed. The answers of the teacher–coaches were compared with previous literature on the effectiveness of outdoor field trip teaching. The poll results agree that student engagement is related to the combination of an extended field trip to a new resource area with a single subject of focus, practice of professional trade skills, new social interactions, and a contest at the end of the trip. The teacher–coaches enjoyed their opportunity to gain knowledge of subjects they teach from local experts and share social and professional interactions. The responses are important because they lend new perspectives to teaching and coaching not reported in the literature, and explain some educational advantages for outdoor field trip contest activities. Future studies to determine the long-term knowledge gain and retention from such an activity as contrasted with conventional field trips and classroom instruction alone are needed.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2012-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2011.0023u","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75194647","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}

This study asked respondents to suggest and rate topics and content they deemed most important to plant breeding graduate programs and curricula related to the areas of knowledge, experiences, skills, and specialties. Examination of private stakeholder recommendations for integration into a student's education and preparation for jobs outside academia was then performed. Knowledge of traditional plant breeding, genetics, statistics, and experimental design, along with emerging topics including database management and ethics, were rated very important. Experiences rated as very important included designing an experiment, as well as field and laboratory data analysis. Stakeholders suggested that experiences focusing on communication, teamwork, and management are key aspects of training. Scientific skills suggested by stakeholders aligned quite well with important knowledge and experience categories and also included skills a student can acquire through a variety of experiences focused on judgment and ideas, time and efficiency in completing tasks, and decision making abilities. The information detailed in this study will be useful to all educators seeking content ideas from private sector stakeholders for curriculum programs. It will also be a valuable tool for new graduate students seeking to understand the knowledge and skill sets that are recommended for a plant breeder prior to seeking a job in the private sector.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4195/jnrlse.2010.0031g","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75308398","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}

This decline prompted a survey of students enrolled in these programs to determine what factors led to their decisions to matriculate there and conversely, what may have made them hesitant to do so. The sample population consisted largely of upper-class forestry majors who attended the 2004 and 2007 Society of American Foresters’ (SAF) national conventions. An analysis of the content of survey responses indicated that students were attracted to majoring in forestry and subsequently pursuing a career in this field by a love of nature or the outdoors. Hesitation arose from concern over low wages, lack of jobs, and a negative public image of forestry. The latter factor may explain why natural resource degree programs perceived as more conservation/sustainability-oriented constitute an increasingly higher proportion of total enrollments in colleges of natural resources compared with forestry. More comprehensive surveys of students from a wider array of professional degree programs are needed to test our findings, and should be coupled to studies of the demand for forestry graduates.","PeriodicalId":100810,"journal":{"name":"Journal of Natural Resources and Life Sciences Education","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78663133","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}
