PBL vs Lecturing
Project Based Lecturing (PBL) vs Text Book based Lecturing
Text books are organized from simple to complex, i.e. starting from simple concepts, the text moves to increasingly more complex concepts. The premise is that the foundation consisting of the first principles must be laid first before comprehension can occur for more difficult ideas. This is how a subject's concepts are viewed by the expert of that field. But, this progression from simple to complex, was not visible to the expert when he started his journey. This is only the understanding that an expert gets when one has reached that vantage point.
On the other hand, PBL approach focuses on the top-down approach. A project typically is a higher level view of a real-life or a life-like situation or phenomenon. It is complex in nature and needs to be decomposed to simpler and simpler concepts till the foundations reveal themeselves. By definition, a project being life-like has sense to it and more importantly makes sense to the students. As such it is more interesting. The line of enquiry from top (more complex) to down (more simpler) are many. If multiple projects are assigned to a class, then each group of students has four to five students. There are enough lines of enquiry to support the learning style of each group member. Because students select their own line of enquiry and pursue it, the process is more dynamic and may even hold surprises for the students as well as the teachers, there is an exhilarating feeling of adventure and discovery that fills us with adrenaline and sharpen our senses. This process where a student exercises his own mind in pursuring different lines of enquiry is more interesting and engaging and self satisfying. Teacher instead of holding the central position in the class becomes a guide or a facilitator. Students as well as the teacher become partners in this journey of exploration, which increases the motivation and inculcates a quest for learning. Instead of a feeling of being herded in a boring direction and made to sit in senseless excercises, which actually necessitate the institution of rewards and punishments, the students embark on journey of excitement and discovery. Teacher as a facilitator needs to just ensure that students are getting a full and rewarding learning experience.
Project Based Learning (PBL)
Project-based learning is an instructional method that provides students with complex tasks based on challenging questions or problems that involve the students' problem solving, decision making, investigative skills, and reflection that includes teacher facilitation, but not direction. PBL is focused on questions that drive students to encounter the central concepts and principles of a subject in a hands-on method. Students form their own investigation of a guiding question, allowing students to develop valuable research skills as students engage in design, problem solving, decision making, and investigative activities. Through Project-based learning, students learn from these experiences and apply them to the world outside their classroom. PBL emphasizes creative thinking skills by allowing students to find that there are many ways to solve a problem. [Source: Wikipedia]
Project-based learning is a dynamic approach to teaching in which students explore real-world problems and challenges. With this type of active and engaged learning, students are inspired to obtain a deeper knowledge of the subjects they're studying. Watch an introduction video.
