Measuring the Effects of a Research-Based Field Experience on Undergraduates and K-12 Teachers

During the summer of 1999, a new type of field course was taught in five of eastern Utah's National Parks and Monuments. It targeted a combination of university undergraduates and K-12 teachers, emphasized development of participants' problem-solving skills, and assessed the effectiveness of several non-traditional teaching methods. The course's primary goal was to teach participants to develop and test their own ideas. The course was also designed to help participants learn to use tools and methods employed by research scientists. A mix of undergraduates and teachers was targeted so that the course could be used to introduce undergraduates to the concept of teaching as a career. Assessments of the course's effectiveness were made on the basis of the achievements of stated outcomes, and by pre-course and post-course testing. Educational levels: Graduate or professional

Debating whether Dinosaurs Should be "Cloned" from Ancient DNA to Promote Cooperative Learning in an Introductory Evolution Course

This interactive internet exercise engages students in cooperative library and web research on a controversial topic in science (and ethics), specifically the cloning of extinct forms of life. To debate the many complex issues embedded in this topic, students have to apply knowledge acquired from a variety of sources about dinosaurs, their evolutionary history, diversity, distribution, physiology, behavior, environmental requirements, and extinction. They must achieve a general understanding of the techniques used to discover and retrieve ancient DNA and to produce a clone from a living adult animal. During an in-class "trial," two teams of students representing six types of specialists argue cases for and against dinosaur cloning. Student "judges" hear testimony, pose questions to the specialists, and render their verdict about whether dinosaur cloning should be allowed. Working cooperatively in small groups and arguing a position in an authoritative fashion requires students to exercise their communication (written and oral), collaborative, and critical thinking skills. This exercise creates a dynamic learning environment in a moderately large introductory geology course and demonstrates the importance of scientific literacy in the contemporary experience.

Bat Algorithm: Literature Review and Applications

Bat algorithm (BA) is a bio-inspired algorithm developed by Yang in 2010 and BA has been found to be very efficient. As a result, the literature has expanded significantly in the last 3 years. This paper provides a timely review of the bat algorithm and its new variants. A wide range of diverse applications and case studies are also reviewed and summarized briefly here. Further research topics are also discussed.Comment: 10 page

NEW CHALLENGES FACING AGRICULTURAL AND RESOURCE ECONOMICS DEPARTMENTS IN THE TWENTY-FIRST CENTURY

Land/grant colleges were established to serve the public via a tripartite system of teaching, research, and extension. Agricultural economists have played a key role in this system in meeting agriculture's needs and are expanding this role to better cover the areas of food, natural resources and the environment. The declining economic importance of agriculture and the growing interest in relegating agriculture to free market forces has resulted in declining formula funding for the land grant system, greater emphasis on competitive funding, demands for greater accountability, and demands for a return to greater focus on public service, problem solving, and stakeholder involvement in the definition of research, teaching, and outreach agenda. Simultaneously, the demand for the traditional "agricultural economics" graduate is declining. This paper reviews the current and long-term issues and trends facing agricultural economics departments, explores the futures of their teaching, research, and outreach programs, and highlights the challenges that will be faced as these departments explore new teaching, research, and service opportunities in the areas of food, natural resources, and the environment. The paper concludes by arguing that for forward thinking agricultural economics departments, these pending changes will represent opportunities for better scholarship, more balance, and more effective service.Teaching/Communication/Extension/Profession,
