Students^ Mathematical Generalization in Solving Numeracy Problems

Question from Mr. Yosep Dwi Kristanto

After watching your presentation on ^Students^ Mathematical Generalization In Solving
Numeracy Problems,^ I found it insightful. I have a couple of questions related to the

First, in Table 4, what does the average in the fourth column represent? I^m curious to
understand how it was determined.
Second, would it be possible for you to share the problems/questions used in your
tests? As your paper^s title suggests, I believe they were related to numeracy, and I^m
interested in exploring the content further.

Hello Mr. Yosep, thank you for your question!
Here is my answer to your question.
Firstly, in Table 4, the result in the fourth column represents the generalizing
ability of the students in total (in the class). For example, in the indicator of
^perception of generality^, it shows that on average 79% of the students met the
indicator. This means that in one class, 79% of the students are able to fulfill the
perception indicator, hopefully you can imagine what I mean.
for the next question, I will input the questions that I used in the test.
In a marching competition, a team plans to make a line pattern with the group
leader in the middle, as shown in the following figure:

Based on this information, choose true or false for the following statements. Write
the reasons that match the data!
a. Each time the pattern increases, the number of members in the line formation
increases continuously.
b. In the 5th pattern formation, the total number of members is 17.
c. If there are 30 people, then to form a line according to the above pattern, 1
person should not be included in the line.
d. The total of members involved in forming the pattern from the 1st pattern to
the 10th pattern is 200.

I constructed this question based on Mason^s indicators.

Hello Ms Titania,

Thank you for your response regarding the results in Table 4. I appreciate the
explanation of the average values representing the generalizing ability of the
students in total.

I still have a question about the percentages of students fulfilling the indicator in
each category (high, moderate, and low). For example, you mentioned that in the
high category, 91% of the students fulfilled the indicator (I hope my interpretation
isn^t mistaken). Considering there were 8 students in this category, the number of
students that fulfill the indicator would be approximately 91% * 8, which is about 7
students. However, when I calculated the percentage based on this, I obtained 7/8 *
100% = 87.5%, which is not close to 91%.

Could you kindly clarify the method used to calculate the percentage of students
fulfilling the indicator in each category? I want to ensure accuracy in interpreting the

Thank you!

Thank you Mr. Yosep for your response.
In table 4, the percentage in column 3 is based on the scores of student^s work, not
the number of students.
So column 3 is a representation of the student scores in each category and column
4 is a representation of the overall student scores in the class.
