Distribution of answers of Japanese students to “Do you like mathematics?” in TIMSS 2011.
Do Japanese junior high school students really dislike mathematics?
Can we rescue them?
TIMSS

2. Purposes Method We aimed to examine the following two hypotheses.
There would be “fake math-dislike” students in Japanese junior high schools.
Informing them of their implicit positive attitude would prevent them from becoming real dislikes.
Method
Participants: Two hundreds and four 7th grade Japanese junior high school students participated in the present study.
Procedure:
Detection of “Fake / Real Math-Dislikes”
Rescue Treatment for a half of the “Fake Math-Dislikes”
Pre/Post assessment of their math achievement in school 2

3. 1) Detection of Fake/Real Math-Dislikes
Self-ratings on like and dislike of mathematics.
　Participants rated twice on a five-point-scale (2,1,0,-1,-2).
　We classified students into the following three groups:
　Favorable (>= 1); Neutral (= 0); and Unfavorable (<= -1)
FUMIE Test (a paper-and-pencil IAT; Mori et al., 2008)
　Participants were classified into two groups:
　　Positive = Those who marked more on the positive task
　　Negative = Those who marked more on the negative task
Positive tasks
Negative tasks
IAQ = (PS-NS) / (PS+NS) /2 が正しいのでは？
Those students who answered they “dislike math” but showed positive implicit scores were regarded as “Fake Math-Dislikes.” 3

4. 1 wk / 2ms / 5 ms / 8 ms / 9 ms / and 1 yr
2) Rescue for “Fake Math-Dislikes”
We randomly divided the Fake / Real Math-Dislike students into the Experimental and Control groups, with having their math achievement scores matched pair-wise.
Detected “FMDs”
Experimental group
(13 boys & 7 girls)
Control
Group
(4 boys & 8 girls)
1 wk / 2ms / 5 ms / 8 ms / 9 ms / and 1 yr
later assessment
Detected “RMDs”
Intervention
group
(12 boys & 6 girls)
We informed only the Experimental students of their implicit positive attitudes toward math.
We also informed Experimental RMDs the same information.
No such information was provided to the Control students.
3) Assessment of
the math achievement
After the rescue treatment, we repeatedly assessed the math achievement of the Experimental and Control Fake / Real Math-Dislike students for one year. Their achievement scores were compared with their pre-test scores before the treatment. 4

5. Results
There were large between-subject differences among the achievement test scores in math for both the Experimental and Control Fake / Real Math-Dislike students. Therefore, we counted how many students improved their scores than the pre-test scores in each experimental condition. (See the table below.　Note; Five absentees removed.)
The frequencies of improved students in the four groups were statistically different (X(3) = 10.02, p < .05, φc = 0.42, X(3) = 12.53, p < .01, φc = 0.47). 5

6. Conclusions
1) The combination of questionnaires and paper-based IAT successfully detected fake math-dislike (FMD) students.
2) Statistically more Experimental FMDs improved their math achievements after nine mouths and one year of the rescue treatment. Meanwhile, it did not work for the RMD students.
3) Accordingly, informing their implicit attitude worked as a preventive intervention for the fake math-dislikes from becoming real math-dislikes.
