Adapting to a changing highschool population
Cora Salm, Jan Eijkel, Erik Faber,Ferdi van der Heijden, Mathieu Odijk
University of Twente, The Netherlands
Changes in the EE curiculum resulting from math and physics deficiencies

Observed problems with freshman students
High school students have problems with:mathematical manipulationsaddiction to graphical calculatorphysical insight in equations
University differs from high school40-hour work weekdiscipline 5.5 mentality not okeagerness to understand
AdditionallyLarge variation in knowledge and skills

Day 1 at university After 5 weeks remedial teaching
Similar results at all 3 technical universities

Problems caused by ? government, new teching methods, old fashioned university teachers, too high expectations, MTV, economy ……
SOLUTIONNew introductory course so that other teachers get “good” students.
8.5 European credits
![Page 5: Adapting to a changing highschool population](https://reader036.fdocuments.in/reader036/viewer/2022062411/5681678c550346895ddcac10/html5/thumbnails/5.jpg)
Introducion EE and electronics
Aim: solve all observed problems, fun and selecting
Cover most topics in EE and point forward
Intertwine classes, excersizes, remedial math. Labworks and project
Final project: challenging, novel, feasable.
Preview of first 2.5 yearsShow relations between courses
especially why math can be usefull
Challenging and fun.
motivating and real EE

What do we want to teach
• Psychological
• Basic math
• Enlarge physical insight
• Introduction EE and electronics
![Page 7: Adapting to a changing highschool population](https://reader036.fdocuments.in/reader036/viewer/2022062411/5681678c550346895ddcac10/html5/thumbnails/7.jpg)
Psychological: Attitude change
How to motivate students•Lot of classes•Guarantee to succes if you work hard•Not preparedNo grade•Test during lectures
Mix theory /experimental work
Questions designed in a way that calculator is no use
Work hard (40 hours/wk)Also study at home
Do NOT aim at 5.5
Eagerness to understand
Calulator only helps if you know what to put in
![Page 8: Adapting to a changing highschool population](https://reader036.fdocuments.in/reader036/viewer/2022062411/5681678c550346895ddcac10/html5/thumbnails/8.jpg)
Mathematical manipulations2 equations 2 unknownsIntegrationDifferentiationAbstract thinkingManipulate formulasFractionsLogarithmicsExponents, Sine, cosine…
How to upgrade math skills•Hide the math in EE-excersizes
•Fluent transition remedial math and new academic math
•Assume they know nothingshow everything on the blackboard
•Do not tell them they know nothing!
•Have extra examples ready
![Page 9: Adapting to a changing highschool population](https://reader036.fdocuments.in/reader036/viewer/2022062411/5681678c550346895ddcac10/html5/thumbnails/9.jpg)
Enlarge physical insight
Equations describe relations in the real world
Transfer to other domains
“If you understand more you need to know less”
How to increase physical insightAnalog situation in other domain
Distill equations(not only solve)
Drilling + lots of lectures

Other results
• Large attendence in class• Students ask questions/interact• Students put in 90-115% of the studyload• Math still perceived math as boring (65%) but
usefull (80%)BUT
• Unclear if students also put in more time in parallel classes
• Studying without teacher (homework) still to be learned later on

SummaryNovel Introductory class IEEEIntertwines theory, math repair, excersizes, labworkLarge improvement on the math proviciency testStudents work hard and are motivatedProgram can easily be adapted when highschool
program changes again
Student are more lazy and need external motivators(compared to the good old days…..)
