Parental Attitudes Regarding School-Based Sexuality Education in Utah

Sexuality education programs can be broadly categorized as either risk-avoidance or risk-reduction approaches. Health educators in Utah public schools must teach a state mandated risk-avoidance curriculum which prohibits the advocacy or encouragement of contraception. Multiple national surveys indicate that parents prefer a risk-reduction approach to sexuality education that promotes abstinence and the use of condoms or contraception for prevention of unwanted pregnancy and sexually transmitted infection. To date, no survey of Utah parents has been conducted.

This study utilized an Internet survey to gather data from 344 Utah parents to analyze their preferences regarding school-based sexuality education, sexuality topics, and support for objectives from the National Sexuality Education Standards. The vast majority of Utah parents surveyed support a risk-reduction approach to sexuality education, a wide variety of sexuality topics, and the majority of National Sexuality Education Standards. Statistically significant differences were identified by parents’ education, income, attendance at religious services, and political affiliation. Results support that Utah laws and education policies should be reexamined to provide for instruction that aligns with professional recommendations, best-practice recommendations based on peer-reviewed research, parental attitudes, and the needs of Utah teens.     

Technology Leadership Perceptions of Utah Elementary School Principals

Abstract

The rapidly expanding use of technology in education requires principals to be prepared as technology leaders; however, many are not currently prepared for this role. It is crucial that principals are prepared in order to lead schools in successful technology integration and support. The primary purpose of this quantitative study was to determine the perceived level of technology leadership preparation of Utah elementary principals using the International Society for Technology in Education (ISTE) Standards for Administrators. The data for this study was collected from 129 Utah elementary school principals and the survey used the ISTE Standards for Administrators as the framework, and findings provide evidence that Utah elementary school principals are not adequately prepared to lead as technology leaders. (Keywords: technology leadership, principal, ISTE Standards for Administrators).     

Intellectual and Personality Characteristics of University of Utah Students

Abstract

The purpose of the study Is to determine if counselors perceive secondary school students differently from teachers. A group of 25 effective teachers, as determined by their respective principals, and a group of 25 counselors-intraining were interviewed by the author. Each subject completed an 84-item Q-sort constructed of items describing an ideal student. Each item on the Q-sort was judged by a three-judge panel to describe a student as being more flexible or more rigid.

The two groups were matched according to degrees earned, sex, and age. The teacher group averaged six more years' experience than the counselor group.

Each subject's Q-sort was scored to produce a flexible score or a rigid score according to how the subject perceived the ideal student. A significant difference at the 0.1 level of confidence was found when Chi Square was used to analyze the data.

This study suggests that perceptual differences occur between two groups of persons in similar helping relationships which may be directly related to the personalities of the helpers. These perceptual differences are necessary for being effective In either helping relationship.     

Twice considered: Charter schools and student achievement in Utah

A relatively small state, Utah presents an interesting case to study charter schools given its friendly policy environment and its significant growth in charter school enrollment. Based on longitudinal student-level data from 2004 to 2009, this paper utilizes two approaches to evaluate the Utah charter school effectiveness: (a) hierarchical linear growth models with matched sample, and (b) general methods of moments with student-fixed effects regressions. Both methods yield consistent results that charter schools on average perform slightly worse as compared to traditional public schools, a result that is primarily affected by the low effectiveness and high student mobility of newly opened charter schools. Interestingly, when charter schools gain more experience they become as effective as traditional public schools, and in some cases more effective than traditional public schools. This research has implications for local and state charter school policies, particularly policies that avoid “start-up” costs associated with new charter schools.     

Science choices and preferences of middle and secondary school students in Utah

This research sought to answer two questions: (1) What are Utah junior and senior high school students' preferences and choices regarding science subjects? (2) Could preferences and choices be related to the type of school, age or gender? Two thousand students from grades six through twelve participated in this study. Findings show that zoology and human anatomy and physiology were most preferred. Ecology was least prefered. Topics in the physical sciences were also low. There was a trend among girls to prefer natural sciences such as botany while boys tended to prefer the physical sciences. Generally, students' choices were limited to those subjects presently taught in the formal school curriculum. They appeared unaware of the many science related subjects outside the texts or the approved course of study.

Teacher attrition in the USA: the relational elements in a Utah case study

Previous work on teacher attrition in the US has indicated that those who stay in the profession and those who leave are not separate homogenous groups. In this study, the lived experience of former teachers is examined to determine the issues that distinguish leavers from stayers. The sample is from the state of Utah, a state with one of the highest attrition rates in the nation. By loosely applying self-thematization theory to collect and analyze data from former teachers, a variety of elements were identified that combined in timing and intensity to influence the decision to leave the profession. These elements are also experienced by teachers who stay. However, in this study, collegial relationships was identified as the mitigating factor regardless of any combination of other factors influencing the decision to leave or stay. Although small-scale convenience sampling was employed, this study allows for an intimate accounting of the relational elements of teaching that exist among educators, which are often overlooked. Implications for teaching and schools are discussed with suggestions for direction of future research on teacher attrition.     

Knowledge Assessment of Food Safety Managers in Utah and Its Implications on the Exam and Instruction

ABSTRACT: Food Safety Manager's Certification is offered through a state‐local Extension partnership in Utah using an online course management system. Exams and course materials were created by an Extension Specialist at Utah State Univ. Extension Agents provide exam and curriculum facilitation in each county. This form of distance education enables access for students in all 29 Utah counties. All 454 students (Jan 2008–Mar 2009) successfully passed the food safety managers exam in 1 or 2 attempts and received certification. Twenty‐nine percent of those taking the exam received certification without accessing any of the course materials. The overall passing exam score mean was 82%. When combining both passing and failing exam attempts, the students' mean was 79%. The students' mean of the lower 25% was only 65%. When evaluating the 7 food safety knowledge domains, students' means were highest in personal hygiene and lowest in facility, equipment, and layout. The lower 25% of students failed to score 70% in 6 of 7 food safety knowledge domains. The English course materials were provided in 3 options where students could select 1 or more: online, textbook, and DVD. For students who chose to access educational materials 67% used online learning, 40% textbooks, and 10% DVDs as part of their study options. Extension Agent feedback on Hispanic students enrolled in the program indicates a need for Spanish language study materials. Overall, the Utah Food Safety Managers program demonstrates a successful state‐local Food Science Extension approach to distance education, online curricula, and the use of computers to facilitate testing and learning.     

The (Dis)inclusion of Latina/o Interests from Utah’s Dual Language Education Boom

Utah’s state planned model of dual language education has grown and spread rapidly. Drawing on critical race theory and LatCrit, we examined state policy documents and promotional materials for their discursive portrayal of Latinas/os. Our analysis revealed a pattern of centering the interests of the White, English-dominant majority and those without an ethnic connection to the target language, while marginalizing or silencing Latina/o interests. Implications for dual language education stakeholders are discussed.
