Table 1: Assumptions Inherent in Objectivism and Constructivism, “Objectivism and Constructivism: Do We Need a New Philosophical Paradigm,” Jonassen, David
Reality (real world)
Objectivism1. External to the knower2. Structure determined by entities, properties, and relations3. Structure can be modeled
• Software Training• Online Library of Training Movies• Learners are professionals seeking to improve their software skill sets
Jonassen:--The important metaphysical position that objectivism makes is that the world is real, that it is structured, and that its structure can be modeled for the learner.

Constructivism1. Determined by the knower2. Dependent upon human mental activity3. Product of mind4. Symbolic procedures construct reality5. Structure relies on experiences/interpretations
• Soft Skills Training• Online Mentor to Mentee Environment (also Mentor to Mentor)• Learners are junior high and high school students • Some learners must complete the tasks as part of a class assignment

Reality (real world)
Mind
Objectivism1. Processor of symbols 2. Mirror of nature3. Abstract machine for manipulating symbols
• Learners view step-by-step procedures narrated by trainers• Learners control the pace of their learning
Jonassen:--The epistemology of objectivism holds that the purpose of the mind is to mirror that reality and its structure.
Mind
Constructivism1. Builder of symbols2. Perceiver/interpreter of nature3. Conceptual system for constructing reality
• Learners are guided through a curriculum designed to prepared them for their chosen profession• Learners must accomplish tasks in order to advance
Murphy:AUTHENTIC ACTIVITIES
KNOWLEDGE CONSTRUCTION
Thought
Objectivism1. Disembodied: independent of human experience2. Governed by external reality3. Reflects external reality4. Manipulates abstract symbols5. Represents (mirrors) reality6. Atomistic: decomposable into “building blocks’7. Algorithmic8. Classification - What machines do
• Learners mirror the movies using exercise files• A short video at the beginning introduces the learner to the trainer followed by the instruction
Thought
1. Embodied: grows out of bodily experience2. Grounded in perception/construction3. Grows out of physical and social experience4. Imaginative: enables abstract thought5. More than representation (mirrors) of reality6. Gestalt properties7. Relies on ecological structure of conceptual system8. Building cognitive models9. More than machines are capable of
Learners communicate with mentors who are experts in their fields Learners ask questions and share experiences Mentors provide scaffolding
Constructivism
MURPHY:--Previous Knowledge Constructions --Consideration of Errors
Jonassen:THOUGHT--Grows out of physical and social experience--Imaginative: enables abstract thought--Grows out of bodily experienceCOMPLEX THINKING (Design of CLEs)
Meaning
Objectivism• Corresponds to entities and categories in the world• Independent of the understanding of any organism• External to the understander
• Meaning has been constructed by the software developers• Learners know they have mastered the software training when they can perform the same tasks without guidance
Meaning
1. Does not rely on correspondence to world2. Dependent upon understanding3. Determined by understander
Meaning is constructed by the learners Learners share their thoughts and experiences through email and on discussion boards Feedback is given by the mentors
Constructivism
Symbols
Objectivism1. Represent reality2. Internal representations of external reality (“building blocks”)
• Real problems are addressed in each movie• Learners can view a list of all of the movies he/she has viewed• Learners can use the movies for quick reference
Symbols
1. Tools for constructing reality2. Representations of internal reality
Mentors and mentees post profile pages to introduce themselves (i.e. interests, hobbies, photos) The online environment is enhanced with a 3D avatar to guide the learner Learners have access to training movies, email, and discussion boards
Constructivism
