The double helix, Math. and Chemistry Univ Sec. School time Göran Svensson, Material and Surface Chemistry Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Something had to be done • Change the courses in Mathematics • Include programming in Mathematics • Merge several chemistry courses into one big • Find natural links between Mathematics and Chemistry • Get the student working from day one • Continuous examination Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Mathematics in Computer Studios Plenary lecture 4 h/week Studio class 4 h/week Class 2 h/week Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Mathematics • Change from an analytical to a more numerical approach • Use MatLab as a tool (programming) • Write new books • Create an good learning environment • Interact with Chemistry Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Eduardo Galeano soul from body and mind from heart Göran Svensson, Material and Surface Chemistry Chalmers University of Technology New books i Mathematics Chalmers University of Technology Two examples from the book Applied mathematics: ISBN 3-540-00890-X Body and Soul is a mathematics education reform project developed at Chalmers University of Technology and includes a series of volumes and software. The program is motivated by the computer revolution opening new possibilities of computional mathematical modeling in mathematics, science and engineering. It consist of a synthesis of Matematical Analysis (Soul), Numerical Computation (Body) and Application. Göran Svensson, Material and Surface Chemistry Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Main Features • The program is based on a synthesis of mathematics, computation and application • The program is based on new literature • Emphasis is put on solving problems, project work and presentations • The program contains most of the traditional material from basic courses in analysis and linear algebra Göran Svensson, Material and Surface Chemistry Chalmers University of Technology What do the student think? The new litterature (to heavy, for those who already know) MatLab (Difficulties with the syntax, need more MatLabknowledge) Computer Studios (Differences between the two groups) 5 book) 48 Extra material (as a complement to the text In general Göran Svensson, Material and Surface Chemistry 32 % 4 34 22 % 3 20 13 % U 50 33 % Chalmers University of Technology Chalmers University of Technology The Chemistry Course Merge one complete course with part of five others Teachers and teaching • One plenary lecture (2*45 min) every week by invited lecturers (180 stud) • Two lectures (2*45 min) every week, five parallell groups lead by professors (25-40 stud) • 2*45 min for practice with a professor available • Teachers from chemistry and mathematics together in class when appropriate • Work in the laboratory (~once a week) •Introductory Chemistry •Inorganic Chemistry •Nuclear Chemistry •Organic Chemistry •Physical Chemistry •Analytical Chemistry •Biochemistry Göran Svensson, Material and Surface Chemistry Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chalmers University of Technology ”Buzz” words Portfolio Learning by doing Göran Svensson, Material and Surface Chemistry M O N EY nt de Selfdirection for life long learning The new plan 3 points The first year tu ns so cu g Fo rnin lea Team-work (Academic WWW teachers, from different diciplines, working as a team) Course evaluation n Pr o tio jec na i ts m xa se e u PBL (problem based learning) no nti o C LMS-system (learning managment system) 180 students 4 points 5 lecture groups 15 laboratory groups 4 points Lecturs by professors 4 points 15 points (22,5 ECTS) 14 points (21,0 ECTS) Göran Svensson, Material and Surface Chemistry Lab. by PhD-students Chalmers University of Technology Chalmers University of Technology Experiences LMS-system • Teachers should be close (same building) (Biochemistry the first year!!!!!!) • One lecture group can have several lecturers (1,2 or 3). Responsible for everything! • People from chemistry and mathematics must meet more • Information, synchronize ......(>30 people) • Control of compulsory moment • Hand in results and comments from Webb-system, only laboratory work FileMaker Pro • Examination online CDML-tags • Questions and answers Runs on a simple PC • No discussion forum!

Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chalmers University of Technology VASA and the S problem Biochemistry Tests •Multiple choice with 0-5 correct alternatives •Maximum three times Equlibrium •Three questions •Encouraged to use MatLab (in their toolbox) •Maximum three times And they who don’t pass?? Göran Svensson, Material and Surface Chemistry Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chalmers University of Technology VASA and the S problem • Instructors from Mathematics (MatLab) • Instructors from Chemistry (the Chemistry) Chemist can help with the mathematics and MatLab (often) The reverse don’t work Göran Svensson, Material and Surface Chemistry Library Fire-practice Chemicals in common products Final exam The eigenvalue problem and molecular orbitals, The Hückel method Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chalmers University of Technology Final exam Chemicals in products • Project running from second to last week • Supervised by a senior student (project leader course, 3p) • Intermediate reports and a final one • Should work as a project group with leader, secretary, webbmaster, etc. (rotates) • Groups with 4-6 students Göran Svensson, Material and Surface Chemistry • • • • Written exam 10 problems in 5 hours All three text books are allowed Notes are allowed, of all kinds as long as they are hand written (labnotes) • Tests for understanding • The way to the answer is more important than the answer itself Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Molecular orbitals by the Hückel method • The method is introduced by maths and chemistry teachers during a shared lecture • The students do some simple calculations by hand • Move to a Hückel program written in MatLab. • Calculate the absorption maximum for lycopene and β-carotene. • Compare with results from the practical session at lab. Theory and practice gave very different answers Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Evaluation • Evaluation by independent experts (e.g. interviews with teachers and students) • Independent evaluation by the students • Interviews with second-year teachers, e.g. ”Fundamental and technical thermodynamics” • Regular meetings with student representativs and teachers • On-line evaluation in the LMS-system Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chalmers University of Technology About Chemistry? • Highest gradings for the webb and the LMSsystem (as always!) • Students are very positive • MatLab is a problem • To small lecture rooms • Problems with the online tests • To much to do, do not have time to prepare • The final exam was to difficult Göran Svensson, Material and Surface Chemistry Final remark • Integration between Chemistry subjects have been very sucessful, but it is more to do • Greater interaction between Chemistry and Mathematics is the way to go • A ”Mathematics for Chemist” toolbox based course will never be our goal Göran Svensson, Material and Surface Chemistry Chalmers University of Technology Chemistry and Mathematics Good idea MatLab This is what the education is all about Difficult to get help, one question/session The Kinetics project worked very well Difficult to know who knows what Chalmers University of Technology THE MatLab END The idea is good but it was a big failure Göran Svensson, Material and Surface Chemistry Göran Svensson, Material and Surface Chemistry
