**What
Math Skills do Physics Students Need to Have?**

(the link to pdf: www.GoMars.xyz/mst/mst.pdf)

In his recent paper (https://www.researchgate.net/publication/308568264_Analysing_the_Competency_of_Mathematical_Modelling_in_Physics) Prof. Redish analyses the set of mathematical skills physics students need to have in order to success in a physics course. He also touches methodology behind his analysis.

As a practitioner, I have developed and successfully used for many years a hands-on approach to the problem of math in physics courses (and I have evidence that this approach has been appreciated by my students: www.GoMars.xyz/evvv.html).

As
a teacher, I don’t need to *guess* what math skills do
students need to know, I need to *know* that!

And the full set of such math skills comes from the full set of problems students need to be able to solve (actually or potentially) during (and after) the course.

Since it is I, who writes the syllabus, selects topics, problems, assignments, it is I who has to make the match between physics problems and mathematical skills. And, of course, I did.

But
I did not express the result of that match using a textual
description (“students need to know …, and need to be able to
perform …”), I expressed it in the form of a set of math problems
*students
need to be able to solve*;
which is basically, a mathematical analogy of FCI (the methodology
behind this approach is presented here:
http://www.teachology.xyz/2020.html).

The general methodology to teaching physics is presented in the series of publications:

1. What does “thinking as a physicist” mean?

http://teachology.xyz/general_algorithm.htm

3. Learning aides for students taking physics.

4. A Map of Operationally Connected Categories as an instrument for classifying physics problems.

http://teachology.xyz/mocc.htm

5. On a definition of science, Intelligence, and AI

https://www.researchgate.net/publication/322056445_On_the_science_of_Artificial_Intelligence

The developed set of math problems (see below) is presented to students at the beginning of each course in the form of a laboratory exercise. Initially, it was handed out to students during the lab time, but eventually it was converted into a webassign.

The instructions note that the “test” will not be graded, but students should apply the best effort, and take notes to all difficulties they may have during the test (and work them out as soon as possible).

There is a natural intention to search for correlations between the grade on the math test, and the final grade for the course. However, that correlation would be misleading. In education, like in quantum mechanics, measurement affects the system. When student know they weaknesses, they can concentrate on fixing them quickly enough, so those weaknesses would not affect their progress in study physics.

**The
“test” is ****not****
an assessing tool, but a ****motivational
instrument****.
**

**Physics
is a data driven science, that is why physics is so successful. **

When teaching physics, in order to maximize learning outcomes of students, we (the instructor, and TFs) try to apply the same approach - which had been so successfully used for doing physics

–
**and for that
we need data****.**

This exercise is designed for collecting data, which every student will be able to use for the following self- assessing activities. The analysis of the data will also help to adjust the course material and making it as productive as possible for the majority of students.

**NO
***personal
***data
will be extracted from these surveys, ALL information will be used
ONLY in the aggregated format (i.e. ***as
a normalized distribution)***;
**

**your
name will be used ***only
***for
taking attendance (and for confirmation of the effort put into the
work, to validate the grade for the IL1). **

**This
is an individual exercise. Every student should use an individual
computer and should not consult with anyone else. **

**Please,
login into webassign.net (follow the instructions in the syllabus).
You should see three short surveys/tests available for you; (a) FCI
probes your current conceptual understanding of mechanical events;
(b) MathSelfTest is designed to assess your mathematical skills; (c)
a student status Pre-Survey (the history of taking math and physics,
course expectations, etc.) presents a general social statistics of
the student body. **

**Please,
do the assignments in the following order (take short brakes when
needed): **

**1.
FCI (1 – 1.5 hours); 2. MathSelfTest (1 – 1.5 hours); 3.
Pre-Survey (about 30 minutes) **

The
first two tests have some questions to which you *should not know
*the answers (questions like that might comprise about one third
of the all questions). For those questions you should provide your
best guess (“trust your gut”). Some questions should be very
obvious for you, in that case do not overthink the question, answer
what first comes to mind, there are no tricks.

**Please,
apply your best effort **(which
is revealed via distinctive indicators, including timing, answers
distribution, etc.), but do not spend on the two first tests more
than an hour and a half per each test (1 - 3 minutes per a
question/problem). The last survey should not take more than a half
of an hour.

Please,
note => **each question can be answered only ONCE**!! For each
test you are given ONLY ONE submission for each question. After you
submit your answer you cannot change it any more. It is useful to
save your answers from time to time during the test (scroll down the
page, click SUBMIT).

During
each test *you will NOT know if your answer is correct or wrong*,
you will NOT see the check mark (neither correct nor wrong; if on
occasion a checkmark appears, just ignore it because it does not mean
anything).

If you need to enter an answer with a decimal point, round it up up to four digits after the decimal point; you can also enter fractions in form nn/mm (for example if the result comes from calculating 10 divided by 3, you can write a fraction 10/3, or a decimal number 3.3333).

Please, keep in mind => each question can be answered only ONCE!! After you submit your answer you cannot change it any more. However, after the due day you will be able to see the answers to FCI and to MathSelfTest at http://www.learn.bu.edu/.
