Teaching Programmable Microcontrollers To Novice Users In A College Of Agriculture: Effects On Attitude, Self-Efficacy, And Knowledge, Grant T. Hood May 2022

Teaching Programmable Microcontrollers To Novice Users In A College Of Agriculture: Effects On Attitude, Self-Efficacy, And Knowledge, Grant T. Hood

Graduate Theses and Dissertations

This thesis consists of two articles that examined an instructional treatment based on the use of Arduino UNO R3 programmable microcontrollers in a fundamentals of agriculture systems technology course at the University of Arkansas. The first article examined students’ breadboarding and programming self-efficacy and knowledge of Arduino. The treatment consisted of a three-class-period instructional treatment, starting with a pretest before instruction to measure students’ baseline interest, knowledge, and self-efficacy of breadboarding and programming Arduino. This was followed with a short 30-minute instructional video explaining basic Arduino programming and breadboarding. Next a hands-on laboratory activity requiring students to breadboard and program …


The Exploration Of Undergraduate Attitudes And Knowledge About International Agricultural Issues And Us Agricultural Policy, Caitlin Bletscher, Megan Gould, Shuyang Qu May 2022

The Exploration Of Undergraduate Attitudes And Knowledge About International Agricultural Issues And Us Agricultural Policy, Caitlin Bletscher, Megan Gould, Shuyang Qu

Journal of International Agricultural and Extension Education

In today’s globalized world, educators and employers generally agree on the necessity for undergraduate agricultural [ag] students to develop a sound understanding of global ag issues and policy. Because of this, many U.S. universities have promoted internationalizing curriculum and increased international study abroad experiences. However, few studies have examined the impact of international experiences on students’ knowledge and attitudes about international ag issues and policies. This study bridges this gap by identifying the relationship between student knowledge and attitude toward international ag issues and U.S. ag policy, and how international experience and demographic variables play a role in that relationship. …


Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase Jan 2022

Biochar: Properties And Potential Benefits For Agricultural Soil In Rwanda, Andromede Uwase

Honors Theses

Physical and chemical soil degradation is becoming a major challenge for agricultural productivity in Rwanda, which is the most important part of the country’s economy. The wide spreading soil degradation in Rwanda is mainly a result of naturally poor soils coupled with unsustainable soil management leading to, for example, accelerated soil erosion, acidification, nutrient loss, compaction, and to decreasing yields. Biochar, as an end product of pyrolysis of biomass in the absence of oxygen, has been proposed as a soil amendment in remediation strategies because of its positive effects on soil productivity relevant parameters such as soil pH, structure, nutrient …
