Student-centered learning means having students actively engaged in many aspects of a course to promote learning. Allowing students to participate in syllabus development is a method that involves students in the course and, in the process, assume responsibility for much of their learning. Students can help set course objectives, decide what is the evaluation criteria and who evaluates, determine and deliver some of the course content, and approve the code of conduct for the class. By helping with the aforementioned areas, students can see the relevance of the course to their needs and interests. They tend to take a greater interest in the course and participate more actively in the class. The process of student involvement in syllabus development requires several steps and utilizes techniques that are presented in the following paper.
This decision case concerns production and marketing problems that many ornamental growers incur. At the retail level, popular ornamental crops are often used as loss leaders to draw the public into stores to make other purchases. As a result, retail buyers are concerned not with quality but with price and volume. To meet the needs of price-conscious buyers, growers may attempt to reduce their production costs by reducing the level of production inputs, with some sacrifice in product quality. The owners of Two Sisters Greenhouses must decide whether they are going to produce lower-quality plants, change marketing strategies, or grow alternative crops to retain their current profit margins. This case study was intended for use in greenhouse management, nursery management, and floriculture courses where students assume the role of a decisionmaker in poinsettia production and marketing.
The interest in using nonchemical alternatives for growth control of horticultural crops has recently increased due to public concerns for food safety and environmental pollution. Several research teams around the world are investigating alternative growth control measures, such as genetic manipulation, temperature, water and nutrient management, mechanical conditioning, and light quality manipulation. This review discusses the recent developments in light quality manipulation as a nonchemical alternative for greenhouse plant height control.
