NLCSA is a research facility for myself and others interested in using case study analysis to deepen our understanding of common sense knowledge and natural learning (how the mind interacts with everyday experiences to develop common sense knowledge).
I am putting here three case study corpora based on experiences with three of my children. Each corpus contains recorded materials (originally videotape, now digitized), text observations, and interpretations of some of those materials.

Begun in 1976 and continuing into the 1980’s, these are some of the earliest studies of children with extensive involvement in computing. The materials are presented separately, for each child, although there is significant overlap and interrelatedness of materials; the organization shows each study is of a person, that it involves ideas, and the materials comprise a rich source of data. The digitizing, development, uploading and interpretation of materials is ongoing and will continue.

My second objective is advancing case study as a discipline by sharing materials publicly so:

  • previous interpretations and analyses can be questioned by others with different viewpoints, and
  • others may offer their own different interpretations of what material interests them.

If you, as a researcher, want to discuss collaboration or to examine in more detail the videos presented here in MP4/ H.264 web format, contact me. Full digital video versions of the files exist (but resolution is limited). If you have suggestions about improving the effort in any way, please let me know. You can contact me directly by email as

Cordially, Bob Lawler
