4- IntroductionThe aim of the study is to examine
whether there is any relation by offering context
rich realistic mathematics education and the
formal mathematics development of students in the
fourth grade of secondary school. Problem

5- Resonance group 20071. Take care for that the
developing of arithmetic and formula skills walks
as a red thread through the entire mathematics
education. 2. Split up all mathematics
subjects of the central written final exam (CE)
in two parts a part, without help (of a graphic
calculator and formula card), and a part with
help.3. Reconsider the role of contexts in the
mathematics education

40- Results- HAVO and VWO students have a low mean
on the Classroom Environment Survey than VMBO
students- The dimension use of symbols has
low mean for each school type - On the Non
Context Rich Realistic Math Test VWO students
score a low mean on generalization- The HAVO
and VWO students means are not significant
different on the Context Rich Realistic Test
Part 1 and 2 and Metacognition Test - The VMBO
and VWO students means are not significant

43- Results- The correlation of the Non Context
Rich Realistic Math Test is higher with the
Context Rich Realistic Math Test Part 1 than Part
2- The correlation between the Context Rich
Realistic Math Test Part 1 and 2 is lower than
the correlation with the Non Context Rich

46- Results- the correlation is calculated for the
total score of each dimension and the
Metacognition Test has a significant correlation
at a 0,01 level (2- tailed) with the three
Mathematical tests- The Classroom Environment
Test has a negative correlationwith two of the
Math tests

47- Conclusion- The difference in math performance
of students by school type is clear- The
distinguishing of the three math tests is not so
clear- The use of symbols is by each school
type low - The perception of Classroom
Environment (attitude) of HAVO students is low
and equal by VMBO and VWO students - The three
math test and Metacognition are correlated - No
correlation between math and language achievement
with the three Math tests - Classroom
Environment correlated negative with the two of
the Math tests

48- Discussion- math education by methods and
instruction too context rich and realistic and
enough formal math development according to
school type- distinct math in horizontal,
processes and procedurals, vertical
mathematization- methods give too little
attention for how to use symbols- Classroom
Environment (attitude of students) measures what
we want

49- Suggestions- more respondents and a
longitudinal study to measure level raising of
the formal mathematic development - the
research instruments can be expand and
developed- the research extended with teachers
findings and ideas- method makers has to
realize that formal math development in the
first three grades has to take place more in each
school type
