Who wants to learn harder? The relationship between conservatism and liberalism, desirable difficulties, and academic learning

Previous work has shown that challenging learning strategies like desirable difficulties improve long-term learning. Nonetheless, because they might be regarded as strict and demanding learning strategies, they should not be perceived as positive by everyone. They should, however, fit conservative political attitudes since those are, among others, positively correlated with individuals’ need for order and structure as well as with challenging learning environments. Hence, we hypothesized conservative political attitudes to be correlated with more positive attitudes towards desirable difficulties, towards the use of desirable difficulties at school, towards the preferred difficulty of the learning process, and towards deeper learning strategies. We conducted three online studies assessing US American students’ political attitudes and their attitudes towards such difficult and challenging learning strategies: Study 1 found correlations among more conservative political attitudes and more positive attitudes towards difficult and challenging learning strategies, whereas Study 2 found no significant linkages among these variables. Study 3 then showed that a more conservative political attitude and favorable ratings of Republican politicians, but also more favorable ratings of Democratic politicians were linked to more positive attitudes towards our dependent variables. Self-reported interest in and importance of politics were also positively correlated with positive attitudes towards difficult learning. Our results indicate that students’ political attitudes are generally linked to positive attitudes towards difficult and challenging learning strategies and are therefore important individual characteristics regarding applications and perceptions of these learning strategies. Future work focusing on these relationships, on causal effects, and on further related variables is valuable.

Sans Forgetica is Not the “Font” of Knowledge: Disfluent Fonts are Not Always Desirable Difficulties

Subsequent recall is improved if students try to recall target material during study (self-testing) versus simply re-reading it. This effect is consistent with the notion of “desirable difficulties.” If the learning experience involves difficulties that induce extra effort, then retention may be improved. Not all difficulties are desirable, however. Difficult-to-read ( disfluent) typefaces yield inconsistent results. A new disfluent font, Sans Forgetica, was developed and alleged to promote deeper processing and improve learning. Although it would be invaluable if changing the font could enhance learning, the few studies on Sans Forgetica have been inconsistent, and focused on short retention intervals (0–5 minutes). We investigated a 1-week interval to increase practical relevance and because some benefits only manifest after a delay. A testing-effect manipulation was also included. Students ( N = 120) learned two passages via different methods (study then re-study vs. study then self-test). Half the students saw the passages in Times New Roman and half in Sans Forgetica. Recall test scores were higher for passages learned via self-testing than restudying, but the effect of font and the interaction were nonsignificant. We suggest that disfluency increases the local (orthographic) processing effort on each word but slowed reading might impair relational processing across words. In contrast, testing and generation effect manipulations often engage relational processing (question: answer; cue: target)—yielding subsequent benefits on cued-recall tests. We elaborate this suggestion to reconcile conflicting results across studies.

Homework questions designed to require higher-order cognitive skills in an undergraduate animal physiology course did not produce desirable difficulties, testing effects, or improvements in information retention

Studies show that retrieval practices such as homework assignments that are completed during the encoding phase of learning benefit knowledge acquisition and retention. In addition, desirable difficulties, which are strategies that intentionally create a greater challenge during initial learning to enhance encoding and retrieval pathways, also benefit learning long term. Our objective was to determine whether weekly homework questions intended to create desirable difficulties by requiring higher-order cognitive skills (HOCS) benefited students’ long-term retention of physiology concepts compared to questions designed to require lower-order cognitive skills (LOCS). Undergraduate students in a junior-level animal physiology course were presented information during weekly laboratory periods, and then required to complete retrieval practices in the form of online homework assignments 5 d after each lab. Homework questions were formatted per Bloom’s Taxonomy to require HOCS (i.e. level 4 or 5) or LOCS (i.e. level 1 or 2). Information retention was assessed the next week via performance on an in-class quiz and again at semesters’ end via performance on a final practical exam. We observed no differences in performance on the in-class quiz or final practical exam between students randomly assigned to complete homework with HOCS questions compared to LOCS questions. However, students that received homework with HOCS questions had decreased (P < 0.05) performance scores on 9 out of the 11 homework assignments compared to those receiving homework with LOCS questions. These findings indicate that desirable difficulties were not created by our HOCS homework questions because students receiving these more difficult retrieval practices did not achieve equal success on them. As a result, this attempt to create variations in cognitive demand did not enhance retention of knowledge in this study.

Balancing Collaboration and Cognitive Load to Optimize Individual and Group Desirable Difficulties

We sought to identify factors that optimize individual learning in complex, technology-enhanced learning environments. Undergraduates viewed tutorials and played a simulation-based game either alone or in groups and in either high or low cognitive load sequences and later took tests measuring comprehension of tutorials and transfer of computer networking skills. A cognitive load by collaboration interaction was found for both immediate and delayed transfer measures, but not comprehension measures. Students working in groups performed best under high cognitive load whereas students working individually performed best under low cognitive load. These findings support the notions of optimal individual and group cognitive load and have implications for leveraging technology to design learning environments that allow students to collaborate and maximize individual learning.

Different Impact of Perceptual Fluency and Schema Congruency on Sustainable Learning

Perceptual fluency, that is, the ease with which people perceive information, has diverse effects on cognition and learning. For example, when judging the truth of plausible but incorrect information, easy-to-read statements are incorrectly judged as true while difficult to read statements are not. As we better remember information that is consistent with pre-existing schemata (i.e., schema congruency), statements judged as true should be remembered better, which would suggest that fluency boosts memory. Another line of research suggests that learning information from hard-to-read statements enhances subsequent memory compared to easy-to-read statements (i.e., desirable difficulties). In the present study, we tested these possibilities in two experiments with student participants. In the study phase, they read plausible statements that were either easy or difficult to read and judged their truth. To assess the sustainability of learning, the test phase in which we tested recognition memory for these statements was delayed for 24 h. In Experiment 1, we manipulated fluency by presenting the statements in colors that made them easy or difficult to read. In Experiment 2, we manipulated fluency by presenting the statements in font types that made them easy or difficult to read. Moreover, in Experiment 2, memory was tested either immediately or after a 24 h delay. In both experiments, the results showed a consistent effect of schema congruency, but perceptual fluency did not affect sustainable learning. However, in the immediate test of Experiment 2, perceptual fluency enhanced memory for schema-incongruent materials. Thus, perceptual fluency can boost initial memory for schema-incongruent memory most likely due to short-lived perceptual traces, which are cropped during consolidation, but does not boost sustainable learning. We discuss these results in relation to research on the role of desirable difficulties for student learning, to effects of cognitive conflict on subsequent memory, and more generally in how to design learning methods and environments in a sustainable way.
