Model for many freshman "lecture" classes.
Teaching online. Reinventing the teacher career.
Teaching is creating conditions in which students learn.
Converting lecture classes to online for efficient use of teacher time.
- Giving the same lecture every semester is inefficient, wastes teacher time.
- A 50 minute lecture is not good design for learning, it is designed for efficient student movement.
- There is another way, especially suited for online learning:
Model for many freshman "lecture" classes
- Break the lecture in 10 minute sections on video, each with its own learning objectives (LO).
- The sections are like the sections in a textbook or the points in a PowerPoint lecture
- For each LO, make up a set of test items that evaluate level of achievement.
- Revise the sections as they need an update.
Use a digital teaching assistant
- Provide a digital teacher assistant (DTA) to manage individual learning by each student.
- Student assignment: Check in with your DTA and watch the 10 minute lecture.
- Then take the test.
- Each section should take about 20 minutes.
- A student should aim to complete 15 sections per week.
- A student completes a section by watching the video, asking the DTA questions (if needed), and passing almost all of the test items.
- The DTA monitors progress for each student and advises the student and the teacher.
- The DTA handles routine questions, using keyword search of the FAQ database.
- Questions the DTA cannot handle are passed to the teacher.
- The teacher answers the question and may update the FAQ database.
Students who do not pass
- Are assigned another lecture or text on the same content and retested on completion.
- (The retest should not duplicate the previous test.)
- On a second failure the DTA would as for help from the teacher.
Benefits of this model
For the teacher
- Teacher does not waste time presenting duplicate lectures.
- Teacher gets prompt feedback on the effectiveness of each section.
- Teacher does not have to handle routine questions.
- Teacher can focus on students really having problems.
- Teacher can improve the course over multiple years and possibly market it later.
For the student
- Students study in blocks of time that better fit their attentions span.
- Students study at times best suited to them--can fit it in with work
- Students get the attention of the teacher when they really need it.
- Quick learners do not waste time while the teacher helps the slow learners.
- Can virtual worlds support large lecture classes? The past is not the future
- You could give live lectures on a virtual campus. But why would you?
- Educational presentations in 3D. In the old days, we called them "lectures". But with modern technology, we don't just stand there and talk.
- A different kind of lecture. Dickens and the London of his time. You can have a lecture without an auditorium. You can even do without slides.
- Once you hear lecture about swimming, you never forget what you learned about lectures. Talking is not teaching.
- Early Cretaceous Meat Eating Dinosaurs by Dr. Bill Schmachtenberg & Dr. Alex Hastings. Lecture and discussion in a virtual world.
- How to present without an auditorium. Present in a simulation of the subject. Valerie Hill tells about Research Row in the digital Dickens Project (excerpts).
