A journey in the inside of a Computer


PC Hardware


  • Input / Output Devices
  • Main Memory – Secondary units of memory
  • CPU (Central Processing Unit) – Pc’s Architectural
  • History of PC’s - Categories of computers


Social Interaction -Joyce, B., Weil, M., & Calhoun, E. (2000). Models of Teaching. Boston: Allyn and Bacon


Like Project based using:

  • Concept mapping
  • Jigsaw ii


Students of High School – Lyceum. The lesson is optional in A or B class – age 16-17

Aims, Objectives & Expected results

is the involvement of students in the acquisition of knowledge, skills and attitudes that concern computer hardware, as well as the use of software like concept mapping, learning management systems or wili, via suitable collaborative processes.

The pupils:

  • Have chosen the lesson!
  • Have basic skills in:
  • Concept Mapping
  • Collaboration Techniques (jigsaw II)
  • Are accustomed using:
  • the internet and
  • pc’ s applications


The Social Interaction strategic jigsaw ii requires that different pupils/students assume specialized roles in reaching the goals of a learning activity. Students become experts on a particular portion of a learning task/ sub-topic(Input / Output Devices, Main Memory – Secondary units of memory, CPU (Central Processing Unit) – Pc’s Architectural, History of PC’s - Categories of computers) and teach others on that subject. We use concept maps, formative and summative assessment.

Descriptions/ Steps


1st. Information Gathering

Students are assigned to jigsaw groups and assigned sub-topics in which they have to develop expertise. They use preexistence sources -materials, books, etc. It is useful to have sheets of works to help them gathering the appropriate information. Each pupil constructs a concept map using f.ex. Cmap ( It could be used as individual assessment.

2nd. Expert Meeting

Expert, after teacher’s feedback, meet to compare cmaps and notes. It’s an opportunity to clarify misunderstanding and be productive members of a group. The communication between teacher – pupils and pupils with each other could be done using a learning management system, f.ex. moodle (forums & wikis), or wiki (main page-discussion). Each team will construct a concept map. Using rating scales –written scales of evaluative dimensions which contains scales of values on wich each dimension is rated – or/and a teacher concept map.

3rd. Team Reports

Experts teach the sub-topic to other jigsaw team member. They organize and summarize their information and become teachers trying to explain their sub-topics to others

4th & 5th. Evaluation and Recognition.

Students take individual quiz on all topics and/or prepare an assessment. Using a rating scale they assess their productivity as members of a group. The role of a teacher is very important because he/she must served as a model helping pupils in note taking, organizing notes, summarize info and presented to others


According to the above, evaluation is both formative (concept maps, notes) and summative (quiz, assessment)
