Quality teaching of math modeling: What do we know, What can we do?
报告人：
Werner Blum, Univ. of Kassel, Germany
• • • • • • • • •
Two introductory real world examples Mathematical modelling competency Students’ modelling activities Aims and perspectives of modelling Teaching modelling Teacher support for modelling activities Strategies for learning modelling Teacher competencies for modelling A final real world example
Effective/quanlity teaching of a&m (applications & modelling)
What do we know empirically about effective teaching of a&m?
Generally speaking, well-known findings on quality teaching of mathematics hold, of course, also for teaching of mathematics in the context of relations to the real world 10 important aspects for teaching methodology for a&m:
Quality teaching of a&m
1 Necessary: effective and learner-oriented classroom
management
(using time effectively, separating learning and assessment recognisably, using students’ mistakes constructively, varying methods and media flexibly, ... Hattie&Timperley 2009; Helmke&Weinert, Baumert et al., Klieme )
Group work particularly suitable for modelling
( Ikeda&Stephens )
Co-constructive group work
( Reusser et al., Messner et al.
)
Quality teaching of a&m
2 Necessary: activate learners cognitively, stimulate students’ own activities
(“Modelling is not a spectator sport”, Schoenfeld et al.
)
Distinguish carefully between students working independently with teacher support and students working alone Crucial: permanent balance between students‘ independence and teacher‘s guidance (“Principle of minimal support”
Aebli
)
Quality teaching of a&m
3 Necessary: activate learners
meta-cognitively
(accompanying and retrospective reflections, advancing strategies)
Quality teaching of a&m
4 Necessary: variety of suitable examples (transfer cannot be expected); in particular: variation of - real world contexts
( Busse )
- mathematical contexts and topics Authenticity not always required but helps to reduce “suspension of sense-making” substantially
( Palm, Verschaffel et al.
)
Quality teaching of a&m
5 Teachers ought to encourage individual solutions In practice, teachers tend to favour their own solution
(Leikin, DISUM)
Reasons for encouraging multiple solutions
(Hiebert&Carpenter, Rittle-Johnson&Star, Schoenfeld, Krainer, Stiegler&Hiebert, Tsamir et al., Neubrand)
MultiMa
(Schukajlow/Krug)
: Students who developed several solutions have higher learning gains
Quality teaching of a&m
6 Competencies evolve in long-term learning processes, beginning with early “implicit models”
(Lesh& Borromeo Ferri, Greer&Verschaffel)
Necessary: repeating and practising Balance between focus on sub-competencies of modelling and focus on modelling competency?
Needed: competence development model(s) Approach to describe competency development ~ KOM
(Niss, Blomhøj, Jensen)
Quality teaching of a&m
7 Also assessment has to reflect the aims of a&m appropriately; analogous quality criteria
(Berry, Haines&Crouch, Houston&Neill, Burkhardt, Izard et al., Antonius/Niss et al., Galbraith&Stillman, Vos, DISUM)
Functions of tests: norms, illustration, diagnosis Model
(Zöttl/Ufer/Reiss 2011)
for assessing modelling sub-competencies and general modelling competency
Quality teaching of a&m
8 Parallel development of competencies and beliefs &
attitudes
→long-term learning processes
Quality teaching of a&m
9 Digital technologies can be powerful tools: experiments, investigations, simulations, visualisations or calculations
(Hoyles&Noss, Galbraith&Geiger, Henn, Wake, Borba, Lingefjärd, Greefrath&Siller, ...)
Extending the modelling cycle
(Greefrath)
Needed: more studies into the effects of technologies
Quality teaching of a&m
10 Case studies: Mathematical modelling can be learned by students supposed there is quality teaching
(Abrantes, Kaiser, Galbraith&Clatworthy, Maaß, Biccard&Wessels, DISUM,...)
However: More research needed, especially small scale studies using a mixture of qualitative and quantitative methods
Quality teaching of a&m
All these activities will not be sufficient Implementation of applications and modelling has to take place systemically:
Teacher competencies for modelling
Teacher’s PCK
Teacher competencies for modelling
PCK
(Ball&Bass, TEDS-M, COACTIV; Maaß, Doerr, Lingefjärd, Kaiser/Schwarz/Buchholtz; Ferri &Blum)

Challenges and opportunities
We have to devise teaching and learning activities for prescriptive modelling cycle unassisted.
, also for situations in which students cannot complete the rudimentary modelling Two focal points of such activities ( opportunities ):
• Students should be engaged in
analysing the hidden or explicit assumptions , requirements , wishes and pre-requisites underlying the mathematisation be) undertaken.
(to
• Students should be engaged
in meta-validation of models
Kaiser: Modelling Competencies
•
Important theoretical and empirical approaches with a special focus on the relation of modelling competencies
•
and modelling process Important approaches for measuring modelling competencies (including sub-competencies )
• • •
Own activities to promote modelling competencies Modelling days / modelling weeks Effectiveness of the holistic versus the atomistic approach to foster modelling competencies

一点感受：中外对比
• 外：多数人来自大学的 数学教育系 （教师
/
研究生）
--
不太关注大学数学，更关注 中小学数学教育 中： 非教育系、大学数学教育为主 • 外：多从教育学、心理学、认知科学等角度研究
--
注重定量研究，或定量与定性研究相结合
--
注重方法论研究
(
规范的研究方法
) --
注重实证研究
(
实验对比；问题要具体
)
中： 定性、经验为主 森林 树木？ 中医 西医？
一点感受：借鉴与改进
• 研究问题越具体越好，不求大而全 切忌写成年终报告、成绩总结、
……
（领导保障，教师关键，学生主体 课程设置与教学，竞赛组织和成绩） • 更深入细致、规范的教学研究，例如： 如何 衡量 某种教学法比另一种好？ （指标、实验） 学生建模时难点在哪？原因何在？ （认知过程） 如何设计教学案例
/
过程？教师作用？ （教学法）
一点感受：教学案例
• 对于建模应用方面的研究（实际建模问题）
--
注重问题来源是否真的实际
--
注重文献综述（目前相关研究的现状）
--
注重结果的分析／检验
--
注重实际解决问题的效果
