Digital formative assessment

Formative assessment example

Digital formative assessment

Digital formative assessment

  • No points are given
  • Only deduction for not making the assignments

Weblectures

Apart from the above described course design, students also have access to the weblectures from our campus video lecture capture system. These weblectures are available directly after the lecture has been given.

Method

Formative Assessment

  • 14 Formative assessments
  • General formative assessment indicator
  • Principal component analysis (PCA)

Lecture Attendance

  • Not compulsory
  • Registered in the first and final cycle of the course
  • Scored as zero or one.
  • Again PCA method to arrive at a single factor for attendance

Analysis

Sample

Our analysis is based on the N = 427 (70% female) students that attended the course.

Lecture attendance and formative assessment

Lecture attendance and formative assessment explained 29% \(F(2, 271) = 55.2, p < 0.001\) of the variance.

  • Lecture attendance \(b = −0.006\) \(t(271) = −0.31, p > .05\)
  • Formative assessment \(b = 0.22\) \(t(271) = 10.49, p < .001\)

Lecture attendance and formative assessment

  • First midterm
    • Attendance explained \(R^2=.03\)
    • Formative assessment results explained 24%
  • Last midterm
    • Both models explained less than 5% of the variance.
    • Significant but negligible.
  • Midterm two and three no lecture attendance data was available
    • Formative assessments explained 23% \(F(4, 368) = 27.74, p < .001\)
    • Formative assessments explained 10% \(F(4, 374) = 10.89, p < .001\)

Reliability of the four exams ranged from .53 to .68 on Cronbach's alpha.

Weblectures

Discussion points

  • Formative assessment relevant
  • Attendance no effect
  • Weblectures might
