Metacognitive Self-Assessment, Competence and Privilege

by Steven Fleisher, Ph.D., California State University Channel Islands

Recently I had students in several of my classes take the Science Literacy Concept Inventory (SLCI) including self-assessment (Nuhfer, et al., 2017). Science literacy addresses one’s understanding of science as a way of knowing about the physical world. This science literacy instrument also includes self-assessment measures that run parallel with the actual competency measures. Self-assessment skills are some of the most important of the metacognitive competencies. Since metacognition involves “thinking about thinking,” the question soon becomes, “but thinking about what?”

Dunlosky and Metcalfe (2009) framed the processes of metacognition across metacognitive knowledge, monitoring, and control. Metacognitive knowledge involves understanding how learning works and how to improve it. Monitoring involves self-assessment of one’s understanding, and control then involves any needed self-regulation. Self-assessment sits at the heart of metacognitive processes since it sets up and facilitates an internal conversation in the learner, for example “Am I understanding this material at the level of competency needed for my upcoming challenge?” This type of monitoring then positions the learner for any needed control or self-regulation, for instance “Do I need a change my focus, or maybe my learning strategy?” Further, self-assessment is affective in nature and is central to how learning works. From a biological perspective, learning involves the building and stabilizing of cognitive as well as affective neural networks. In other words, we not only learn about “stuff”, but if we engage our metacognition (specifically self-assessment in this instance), we are enhancing our learning to include knowing about “self” in relation to knowing about the material.

This Improve with Metacognition posting provides information that was shared with my students to help them see the value of self-assessing and for understanding its relationship with their developing competencies and issues of privilege. Privilege here is defined by factors that influence (advantage or disadvantage) aggregate measures of competence and self-assessment accuracy (Watson, et al., 2019). Those factors involved: (a) whether students were first-generation college students, (b) whether they were non-native English-language students, and (c) whether they had an interest in science.

The figures and tables below result from an analysis of approximately 170 students from my classes. The narrative addresses the relevance of each of the images.

Figure 1 shows the correlation between students’ actual SLCI scores and their self-assessment scores using Knowledge Survey items for each of the SLCI items (KSSLCI). This figure was used to show students that their self-assessments were indeed related to their developing competencies. In Figure 2, students could see how their results on the individual SLCI and KSSLCI items were tracking even more closely than in Figure 1, indicating a fairly strong relationship between their self-assessment scores and actual scores.

Correlation with best-fit line between actual competence measures via a Science Literacy Concept Inventory or SLCI (abscissa) and self-assessed ratings of competence (ordinate) via a knowledge survey of the inventory (KSSLCI) wherein students rate their competence to answer each of the 25 items on the inventory prior to taking the actual test.

Correlation with best-fit line between the group of all my students’ mean competence measures on each item of the Science Literacy Concept Inventory (abscissa) and their self-assessed ratings of competence on each item of the knowledge survey of the inventory (KSSLCI).

Figure 3 demonstrates the differences in science literacy scores and self-assessment scores among their different groups as defined by the number of science courses taken. Students could readily see the relationship between the number of science courses taken and improvement in science literacy. More importantly in this context, students could see that these groups had a significant sense of whether or not they knew the information, as indicated by the close overlapping of each pair of green and red diamonds. Students learn that larger numbers of participants can provide more confidence to where the true means actually lies. Also, I can show the meaning of variation differences within and between groups. In answering questions about how we know that more data would clarify relationships, I bring up an equivalent figure from our national database that shows the locations of the means within 99.9% confidence and the tight relationship between groups’ self-assessed competence and their demonstrated competence.

categorical plot by number of college science courses completed — Figure 3. Categorical plot of my students in five class sections grouped by their self-identified categories of how many college-level science courses that they have actually completed. Revealed here are the groups’ mean SLCI scores and their mean self-assessed ratings. Height of the green (SLCI scores) and red (KSSLCI self-assessments) diamonds reveals with 95% confidence that the actual mean lies within these vertical bounds.

Regarding Figure 4, it is always fun to show students that there’s no significant difference between males and females in science literacy competency. This information comes from the SLCI national database and is based on over 24,000 participants.

categorical plot by binary gender — Figure 4. Categorical plot from our large national database by self-identified binary gender categories shows no significant difference by gender in competence of understanding science as a way of knowing.

It is then interesting to show students in that, in their smaller sample (Figure 5), there is a difference between the science literacy scores of males and females. The perplexed looks on their faces are then addressed by the additional demographic data in Table 1 below.

categorical plot by binary gender for individual class — *Figure 5. Categorical plot of just my students by binary gender reveals a marginal difference between females and males, rather than the gender-neutral result shown in Fig. 4.*

In Table 1, students could see that higher science literacy scores for males in their group were not due to gender, but rather, were due to significantly higher numbers of English as a non-native language for females. In other words, the women in their group were certainly not less intelligent, but had substantial, additional challenges on their plates.

Students then become interested in discovering that the women demonstrated greater self-assessment accuracy than did the men, who tended to overestimate (Figure 6). I like to add here, “that’s why guys don’t ask for directions.” I can get away with saying that since I’m a guy. But more seriously, I point out that rather than simply saying women need to improve in their science learning, we might also want to help men improve in their self-assessment accuracy.

categorical plot by gender including self-assessment data — Figure 6. The categorical plot of SLCI scores (green diamonds) shown in Fig. 5 now adds the self-assessment data (red diamonds) of females and males. The trait of females to more accurately self-assess that appears in our class sample is also shown in our national data. Even small samples taken from our classrooms can yield surprising information.

In Figure 7, students could see there was a strong difference in science literacy scores between Caucasians and Hispanics in my classes. The information in Table 2 below was then essential for them to see. Explaining this ethnicity difference offers a wonderful discussion opportunity for students to understand not only the data but what it reveals is going on with others inside their classrooms.

*Figure 7. The categorical plot of SLCI scores by the two dominant ethnicities in my classroom. My campus is a Hispanic Serving Institution (HSI). The differences shown are statistically significant.*

Table 2 showed that the higher science literacy scores in this sample were not simply due to ethnicity but were impacted by significantly greater numbers of first-generation students and English as a non-native language between groups. These students are not dumb but do not have the benefits in this context of having had a history of education speak in their homes and are navigating issues of English language learning.

When shown Figure 8, which includes self-assessment scores as well as SLCI scores, students were interested to see that both groups demonstrated fairly accurate self-assessment skills, but that Hispanics had even greater self-assessment accuracy than their Caucasian colleagues. Watson et. al (2019) noted that strong self-assessment accuracy for minority groups comes about from a need for being understandably cautious.

Groups’ collective feelings of competence, on average, are close to their actual competence. Explaining these results offered a wonderful discussion opportunity for students.

Figure 9 shows students that self-assessment is real. In seeing that most of their peers fall within an adequate range of self-assessment accuracy (between +/- 20 percentage points), students begin to see the value of putting effort into developing their own self-assessment skills. In general, results from this group of my students are similar to those we get from our larger national database (See our earlier blog post, Paired Self-Assessment—Competence Measures of Academic Ranks Offer a Unique Assessment of Education.)

The distribution of self-assessment accuracy of my students in percentage points (ppts) as measured by individuals’ differences between their self-assessed competence by knowledge survey and their actual competence on the Concept inventory.

Figure 10 below gave me the opportunity to show students the relationship between their predicted item-by-item self-assessment scores (Figure 9) and their postdicted global self-assessment scores. Most of the scores fall between +/- 20 percentage points, indicating good to adequate self-assessment. In other words, once students know what a challenge involves, they are pretty good at self-assessing their competency.

The distribution of self-assessment accuracy of my students in percentage points (ppts) as measured by individuals’ differences between their postdicted ratings of competence after taking the SLCI and their actual scores of competence on the Inventory. In general, my students’ results are similar in self-assessment measured in both ways.

In order to help students further develop their self-assessment skills and awareness, I encourage them to write down how they feel they did on tests and papers before turning them in (postdicted global self-assessment). Then they can compare their predictions with their actual results in order to fine-tune their internal self-assessment radars. I find that an excellent class discussion question is “Can students self-assess their competence?” Afterward, reviewing the above graphics and results becomes especially relevant. We also review self-assessment as a core metacognitive skill that ties to an understanding of learning and how to improve it, the development of self-efficacy, and how to monitor their developing competencies and control their cognitive strategies.
