Why High-performing Peer Groups Can Undermine Student Success
It would seem that being surrounded by very capable classmates should boost a student's ambitions and competitive spirit and encourage hard work and high academic performance. However, according to Yulia Kuzmina, the reverse is also possible, when students feel inferior and less confident in comparison to more successful students, which can impact their progress at school and future education plans.
Unfavourable Comparison Undermines Self-esteem
A child's interest and success in learning a subject strongly depends on their academic self-esteem, i.e. self-assessment of their academic abilities and subject-specific skills. Academic self-esteem has been found to predict:
- further academic success. Students who are confident in their abilities continue to achieve better results;
- interest in the subject. The higher a child's assessment of their own subject-specific capabilities, the more interested and involved in this subject they tend to be, often leading to a lifelong career in this field.
According to Kuzmina, students in high-performing classes tend to have lower academic self-esteem than their peers in classes with moderate performance. The culprit is a comparison effect. By comparing themselves with more successful classmates in the former case, a child can feel less confident, whereas in the latter case, the comparison is more favourable and the chances of underestimating one's abilities are lower. This is what the phrase 'big frog in a small pond' refers to.
How Frogs Shrink in Size
Academic self-esteem is based on both internal and external comparison. Comparing their own abilities and achievements in different fields of knowledge, a student forms an opinion concerning their predisposition to a certain subject (internal comparison). They also compare their performance in a subject to that of their classmates (external comparison). Students naturally tend to feel more capable amidst weaker peers, but assess the same level of performance as mediocre compared to better-performing classmates.
Admittedly, attending a strong, high-performing school can also contribute to a student's self-esteem due to a 'glory effect' and feeling inspired by the school's elite status. "But even assuming the status effect, the big frog in a small pond phenomenon can outweigh its positive aspects," according to the researcher.
Group Average Grades Affect Self-esteem
Kiuzmina examined student self-esteem in high-performing groups using mathematics as an example. Her paper is based on data from the Trajectories in Education and Careers longitudinal panel surveys of more than 4,000 Russian students. The students were first surveyed 2011 when they were in the eighth grade, and then again in 2013 and 2014, when they were in the 10th and 11th grades.
A regression analysis was performed using the following data:
- individual student performance in mathematics (eighth-graders' TIMSS scores);
- student position in their class based on scores;
- school quality (focus on student performance; type of school);
- self-assessment in mathematics (ninth-graders, 12 months after TIMSS);
- grade in algebra (tenth-graders) and USE points (expected and actual);
- educational plans (university enrolment);
- likelihood of choosing a career in STEM (science, technology, engineering, mathematics), and some others.
To measure student self-esteem in mathematics, they were asked to agree, on a scale of several points, with statements ranging from 'I am not very good at mathematics' to ‘In a mathematics class, I can understand how to perform even the most difficult assignments’. Based on the above data, the researchers examined students' academic self-esteem over several years.
The study reveals that the higher a student's TIMSS score, the more confident they feel. However, group averages can also affect one's perception of their own abilities: students in better-performing groups "tend to have lower mathematical self-esteem than their peers with the same TIMSS points in groups with lower average scores," Kuzmina notes.
Educational Trajectory Affected by Position in Class
How one measures oneself against peers can have implications for future academic progress: the stronger a school class, the lower an individual students' expectations and academic achievements later on, and this effect is mediated by academic self-esteem.
The study indicates that students in classes with higher average TIMSS scores in eighth grade had lower grades in algebra two years later as tenth-graders than their peers with the same individual TIMSS scores in classes with lower average academic performance. In addition to this, students in classes with high average TIMSS scores were less likely to report plans to get enrolled in a university.
These findings can be explained by the relative deprivation theory. Students in a group of high-performing peers tend to place higher demands on themselves but are often unable to meet them. Failure to live up to self-imposed standards can "lead to frustration and refusal to set ambitious career goals later in life," according to Kuzmina.
However, the big frog in a small pond effect only works when it comes to choosing a prestigious career. If a career is not considered very attractive, this effect does not make a difference. According to the study's findings, the likelihood of choosing a career in STEM is not affected by the average academic performance of a student's peer group – perhaps because many Russian students do not consider careers in science and technology prestigious enough for them.
Benefits of High Standards
It would be incorrect to assume, however, than being surrounded by highly-performing peers at school is bound to ruin a child's future.
According to Kuzmina, those whose performance is average or higher than average in the peer group can benefit from this demanding environment. The positive effect is achieved by 'upward comparison', when a student measures themselves against someone of similar ability but slightly higher performance. The gap in performance then does not appear too big to tackle, causing the student to raise their standards and try harder – which, in turn, can strengthen their confidence rather than undermine it.
