Enhancement of traditional mode of teaching based on the experience of project-based learning
Project based learning (PBL) has become more popular due to its student centered nature of learning compared to traditional modes of learning. However, it is not always feasible to implement it due to several reasons. At the University of New South Wales, the PBL mode was trialled on an introductory Digital Signal Processing course for two consecutive years and the evaluation was previously reported. After that, based on the experience of PBL implementation, some elements of PBL have been incorporated with traditional mode of teaching to enhance the traditional mode and that enhanced traditional mode have been continued. The experience of enhancing the traditional mode with components derived from PBL, particularly the inclusion of conceptual design presentation and laboratory tests, are promising. This paper presents the task description of PBL and experience of how some of the components of PBL can be utilized to enhance the traditional mode of teaching.
Implementation of Project Based Learning: Lessons Learned
Project Based Learning (PBL) is a teaching and learning methodology where students develop projects under real conditions to acquire the knowledge and develop the skills required for their profession. In this article we discuss the lessons learned from two teachers who implemented different PBL approaches in three courses from the Bachelor in Computer and Informatics at the University of Costa Rica, during three semesters. We discuss the main considerations and decisions associated to project design elements and teaching practices. Among the main benefits identified by teachers when using PBL are the high motivation of students and the natural development of soft skills. Among the greatest challenges are (1) the design of learning assessment, considering technical aspects, soft skills, self- and peer- evaluations; (2) continuous feedback to students on their progress in the project and in team dynamics (and its consequent time investment); and (3) the necessary balance between designing a challenging and realistic project that enables the achievement of the course’s learning objectives. We recommend the use of agile methodologies such as Scrum, which align very well with PBL principles, as well as the use of hybrid PBL methodologies, which include complementary didactic strategies to achieve the learning objectives of the course.
A survey of aquaculture production economics and management
Abstract The literature on production economics and management of fish culture has grown as aquaculture has matured as a commercial industry. Salmon, catfish, shrimp and trout are the focus of this literature survey as a reflection of the volume of research that has been completed on these species and their importance in US production and world trade. In addition, a discussion of low resource production systems is included that is dominated by tilapia and carp culture systems. A brief overview of the principles of aquaculture production economics and management is presented followed by a review of economic studies.
