Comparing Piaget and Vygotsky Discussion Guide
Both are constructivists and they disagree about the source of development. Summarising each in turn is not a comparison, and the prompt asks for both compare and contrast.

Two theories that disagree about where thinking comes from
Both theorists are constructivists — children build understanding rather than receiving it — and both reject the idea that a child is a small adult. That is the compare half and it should be brief, but it should be present, because a contrast with no baseline reads as two summaries. The contrast is where the marks are, and it comes down to one question: where does development come from? For Piaget, it is largely internal. The child acts on the world, encounters disequilibrium, and reorganises their thinking through assimilation and accommodation, moving through invariant stages — sensorimotor, preoperational, concrete operational, formal operational. Social interaction matters mainly by producing the conflict that provokes reorganisation. For Vygotsky, development is social first and internal second. Higher mental functions appear between people before they appear within the individual, language is the primary tool of thought rather than a product of it, and learning leads development rather than waiting for it.
That disagreement has consequences you can name, which is what turns a comparison into an argument. The zone of proximal development is Vygotsky's most useful concept precisely because it contradicts a stage-readiness account: what a child can do with support today predicts what they will do alone tomorrow, so instruction should aim slightly ahead rather than waiting for readiness. Piaget's stages, taken strictly, imply the opposite — teach at the stage the child is in. Both have empirical trouble worth mentioning: Piaget's stage ages have been repeatedly shown to be too late when tasks are simplified, and Vygotsky's concepts are harder to operationalise and were left unfinished by his early death. Then answer the practical question the prompt implies by supplying a play video: scaffolding, peer collaboration and guided participation come from Vygotsky, while discovery learning and hands-on concrete materials come from Piaget, and a classroom uses both.

Course-wide instructions that accompany this question
Important information for writing discussion questions and participation Hi Class, Please read through the following information on writing a Discussion question response and participation posts. Contact me if you have any questions. Important information on Writing a Discussion Question Your response needs to be a minimum of 150 words (not including your list of references) There needs to be at least TWO references with ONE being a peer reviewed professional journal article. Include in-text citations in your response Do not include quotes—instead summarize and paraphrase the information Follow APA-7th edition Points will be deducted if the above is not followed Participation –replies to your classmates or instructor A minimum of 6 responses per week, on at least 3 days of the week. Each response needs at least ONE reference with citations—best if it is a peer reviewed journal article Each response needs to be at least 75 words in length (does not include your list of references) Responses need to be substantive by bringing information to the discussion or further enhance the discussion. Responses of “I agree” or “great post” does not count for the word count. Follow APA 7th edition Points will be deducted if the above is not followed Remember to use and follow APA-7th edition for all weekly assignments, discussion questions, and participation points. Here are some helpful links Student paper example Citing Sources The Writing Center is a great resource Welcome to class Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to. I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you. Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted. If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations. Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements. Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week. I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!

Review before submission
Common mistakes
- Summarising each theorist in turn without comparing them.
- Omitting what they agree on, so the contrast has no baseline.
- Describing the zone of proximal development as simply helping a child.
- Ignoring the evidence that Piaget's stage ages are too conservative.
Submission checklist
- Have you stated the shared premise as well as the disagreement?
- Is the disagreement expressed as a single question?
- Does each theory produce a different classroom practice?
- Have you noted at least one criticism of each?
