Does Formative Assessment Improve Student Learning and Performance in Soil Science?

Soil science students are required to apply knowledge from a range of disciplines to unfamiliar scenarios to solve complex problems. To encourage deep learning (with student performance an indicator of learning), a formative assessment exercise was introduced to a second‐year soil science subject. For the formative assessment exercise, students were required to prepare a draft of a critical review of a current topic in soil science, and then (following guidance from staff members) provide feedback to each other through a peer assessment exercise. In contrast to expectations, the formative assessment did not appear to improve overall student performance in this task based upon their grades for this task. Furthermore, despite being given an exemplar and attending a workshop where tactics for searching the scientific literature were discussed, this did not increase the likelihood that students would cite studies from the scientific literature when conducting their critical review. Regardless of these observations, the students were positive and appreciated the feedback they received through the exercise. This study demonstrates the need to ensure that feedback is effective and enables students to identify their weaknesses and modify their work accordingly.

Developing a Foundation for Constructing New Curricula in Soil, Crop, and Turfgrass Sciences

Some soil and crop science university programs undergo curricula revision to maintain relevancy with their profession and/or to attract the best students to such programs. The Department of Soil and Crop Sciences at Texas A&M University completed a thorough data gathering process as part of its revision of the undergraduate curriculum and degree programs in 2010. The purpose of this study was to determine the scientific and technical knowledge, skills, and abilities needed by graduates for career success in 2015 and beyond. Data were collected from three expert panels (soils, crops, and turfgrass) using the Delphi method. Scientific and technical knowledge, skills, and abilities in water‐related issues were indicated as a necessary curriculum item by all three panels. Soil science experts indicated that water studies should focus on movement of water in soils and the contribution of soils to water quality, whereas crop and turfgrass experts emphasized the management of water as a resource. Both the soil and crop panels specified a need for study in data collection and analysis, problem solving, and using scientific reasoning. Turfgrass experts emphasized the need for students to learn business principles and compliance with external regulations. All three groups designated the importance of including soft skills, such as communicating effectively, working collaboratively, and personal and social responsibility, as important curriculum components for students’ career success. These data will serve as the foundation for constructing new curricula and potentially new degree programs in the Department of Soil and Crop Sciences at Texas A&M University.

Using Student Competition Field Trips to Increase Teaching and Learning Effectiveness

Teaching and learning effectiveness may be enhanced in small‐class settings where teachers can tailor materials and methods to individuals. 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.

Introduction to Plant Breeding Learning Activity: Wheat

This learning activity guides students/learners through the basic process in a wheat breeding program. Wheat is a self‐pollinated crop that breeders improve by crossing different cultivated varieties. Through careful crossing, observation, and further selection, breeders make better plants for producers. Biotechnology such as molecular markers aids breeders in the selection process by allowing them to observe the genes present in the DNA of wheat. Using the information from DNA and data collected in the field allows breeders to select plants with traits of interest. This activity uses wheat as a case study to uncover concepts such as pollination, inheritance of traits related to a single gene, selection for herbicide resistance, and molecular marker technology for selecting genes leading toward high protein level expressions. There is an interactive feature called the “breeder's notebook,” which allows users to review concepts while completing the activity. A discussion of genetic engineering and its relation to wheat breeding programs is also provided in the activity. The education material is designed for introductory‐level college students and is also useful for extension education.Running this activity requires Adobe Flash Player.
