Writes raw attempts, observed-attempt scores, or gradebook rows to a CSV file using readr::write_csv().

  rule = "last",
  include_unregistered = TRUE
)

Arguments

con: A DBI connection.
path: Output CSV path.
type: Export type. Use "attempts" for raw attempts, "scores" for observed-attempt scores, or "gradebook" for scores based on registered expected questions.

Examples

db_path <- tempfile(fileext = ".sqlite")
csv_path <- tempfile(fileext = ".csv")

track_attempt(con, "student_001", "module_01", "q1", "mean(x)", score = 1, max_score = 1)
export_results(con, csv_path, type = "attempts")
DBI::dbDisconnect(con)
