Individual Differences

Students differ from each other in multiple dimensions—for example, in their identities, stages of development, and personal histories—and these differences influences how they experience the world and, in turn, their learning and performance

Of course each student is unique. But what research confirms over and over is that student differences, far from being irrelevant, impact learning. 

While the other principles of learning focus on the commonalities of the learning process (for instance, everybody benefits from practice; everybody can use feedback), the first principle focuses on the differences. Of course each student is unique. But what research confirms over and over is that student differences, far from being irrelevant, impact learning. For instance, where students are in their development (that is, their maturity) determines how deeply they can process the content. And the identities and histories of each student have likely shaped how they have been treated by society, shaping their expectations of what is possible for them.   
 
Identity Characteristics 
Students differ in many respects, such as age, gender, race, sexuality, socioeconomic status, ability, religious beliefs, and so on. In addition to these demographic characteristics, other identities are salient to each student, such as their veteran, athlete, first gen, or Greek system status. It is important to note that the brain does not present observable differences along these identity lines, save for learning disabilities. Therefore, in a neutral world, these identities might not matter. But in the world we live in, they do matter, in measurable ways (Lovett et al. 2023). Students who have been stereotyped all their life report the psychological pressures those stereotypes exert on them, taking energy away from learning. Students who have been bullied, ridiculed, or discounted  through their primary and secondary education, might have formed expectations about their college years that limit how they are willing to engage with the material. Students from different cultures might communicate in ways that are seen as less valid in our culture, impacting their ability to have their contributions recognized in full. The literature documents many more instances of how learning and performance can be impacted by a student’s own background. If the requirement for being an effective instructor is to understand all the possible backgrounds and identities students bring to the table and all the ways in which those might impact their learning, good instructors would be few and far between. Instead of being overwhelmed by this body of scholarship, our best bet is to ensure students understand that we do not behave as if all students came from our same background, shared the same cultural differences, and nurtured the same aspirations as ourselves. Who are my students? If that is our guiding question, and the starting point of our teaching that we approach with curiosity, empathy, and flexibility, it will show the students the powerful message that they belong in our course. 
 
Levels of Development 
Research shows that the developmental gains students make in college dwarf the gains in knowledge (Mayhew et al. 2016). Students are developing autonomy, confidence and a sense they can handle life challenges, interpersonal skills, integrity, a sense of purpose, sophisticated epistemologies, and a positive sense of their gender, racial, and other social class identities.  
 
How do humans develop? Research shows that we move forward along our trajectory when life’s challenges reveal the inadequacies of our current ways of thinking and coping and draw us to develop more sophisticated ones. This insight is important for us as we design the pedagogical challenges in our courses. If students do not feel challenged enough, they will feel no need to move forward; if the  challenge feels unsurmountable, they will foreclose development and possibly even regress. Here, out of all the dimensions of development, we will focus on intellectual development.  
 
Intellectual development. Researchers in this area have tried to map trajectories for students’ conceptions of what it means to learn and to know something, and consequently for the role of the teachers and learners at each stage. Of course, student go through a great deal of maturation already in primary and secondary schools, but their epistemologies might still be unsophisticated for the kind of intellectual effort college requires.  
 
At the lowest level, students might be in a position called Dualism, or Received Knowledge (Perry 1997; Belenky et al. 1984). In this view, the world is easily partitioned in true and false facts, and to know something means to memorize all the true facts about the topic. The role of the professor is to provide all the facts, and the role of the students is to regurgitate them back on the day of the test. 
 
The existence of enduring issues for which we do not have one right answer or viewpoint is frustrating and eventually ushers in the next stage, Multiplicity or Subjective Knowledge. Here, to know something means to memorize all the different, sometimes opposite, perspectives on the issue. While this transition is frustrating, it brings in the realization that people might have valid points even when they disagree, and the empowering possibility that one might disagree with the textbook and the professor, making learning a personal exercise. 
 
Everybody is entitled to their opinions, but some opinions are better than others, depending on the evidence they are based. This realization propels students to the next stage, Relativism or Contextual Knowledge. This is a qualitative shift, in that knowledge now is not defined by the number of facts accumulated, but by the ability to justify one’s positions and connect pieces, interpret findings, draw inferences, argue a case, research missing pieces and in general think critically. At this stage, professors who bring in multiple perspectives and probe students’ thinking are met with appreciation rather than the exasperation of the previous stages. 
 
The danger of this stage is intellectual paralysis, because no perspective is perfect and a relativistic outlook is acutely aware of the limits of each perspective. But in order to act in the world, students need to commit to one perspective over others and use it. The Commitment is provisional, and could change if new information emerges. This brings people full circle to picking one perspective over the others, but not in the blind fashion of the dualistic stage. Rather it is a nuanced position, so sophisticated in fact that only a minuscule percentage of students reaches it in the college years. 
 
Asset-Based Approaches 
Instructors already have to keep up with the evolving content in their fast-paced fields. If the result of reading about student differences is merely to add dimensions of knowledge to incorporate in one’s teaching—and this documents barely scratches the surface of that literature—the result would be quickly overwhelming. Indeed, many instructors approach this topic with the question “how do I deal with X and Y groups of students in my course?”  One could enroll in semester long graduate courses on student development, and even that might not be enough to answer the question. So let’s not move with that question. Let’s not start from the implication that the variety of students in our courses is a problem to solve. If we flip this stance, we can treat the diversity of our students as an asset to our teaching. A diversity of student experiences means a diversity of perspectives to contribute to our courses. If we create an environment where everybody feels their contributions are welcome and needed, (see principle #7) the result will boost the collective learning. In fact, studies confirm that, when working in groups, the diversity of the problem-solvers matters more than their individual ability (Page 2008). The positive outlook from an asset-based approach, grounded with the strategies from the other principles of learning, will create a better learning experience for all of our students.
