Game-based learning is supposed to motivate learners. However, to what degree does motivation driven by interest in playing an instructional game affect learning outcomes compared to motivation driven by interest in the very learning process? This is not known. In this study with a unique design and intervention, young adults (N = 128; a heterogeneous sample) learned how to control an electro-mechanical device in a 40-minute-long learning session integrated into a 2-hour-long educational live action role-playing game (edu-LARP). Edu-LARPs are supposedly engaging games where players take part in team role-playing by physically enacting characters in a fictional universe. In our edu-LARP, players had to understand how the to-be-learned device worked in order to win the game. Departing from typical game-based learning research, learning- and playing-related variables were assessed for each learner separately (i.e., a within-subject design). Affective-motivational factors related to playing (rather than learning) predicted learning outcomes in a positive, but considerably weaker, way compared to learning-related, affective-motivational factors. Developed interest in LARP-like games was primarily related to enjoying the game rather than better learning outcomes; whereas, developed interest in the instructional domain was primarily related to enjoyment of learning and better learning outcomes. Overall, autonomous motivation to play was connected to higher learning outcomes, but this connection was weak.

We conducted a meta-analysis of 33 independent samples (N = 2924) to address whether adding anthropomorphic faces to multimedia graphics and/or adding pleasant colors are effective emotional design approaches. We found significant positive meta-analytic effects for retention (k = 18, d+ = 0.387), comprehension (k = 14, d+ = 0.317), and transfer (k = 27, d+ = 0.327) under a random-effects model. Effects for affective-motivational variables were mixed, with a robust effect for intrinsic motivation (k = 23, d+ = 0.255), a weaker effect for liking/enjoyment (k = 20, d+ = 0.109), and a marginal effect for positive affect (k = 15, d+ = 0.113). The manipulations did not significantly (ps > .227) influence perceptions of learning (k = 11, d+ = 0.097) or effort (k = 20, d+ = 0.051), but reduced perceptions of difficulty (k = 14, d+ = −0.208). Four of the outcome variables (retention, transfer, intrinsic motivation, and perceived effort) were sufficiently heterogeneous. There was no major issue with publication bias, influential cases, or outliers. With one exception, there was no evidence of moderation by experimental contrast, dynamicity of materials, age, language/culture, prior mood, time-on-task, and publication type after adjusting for multiple comparisons. There was provisional evidence that age moderated the effect of the manipulations on intrinsic motivation, such that larger effects were revealed for children compared to older learners. Altogether, anthropomorphisms/colors appear to be useful design principles.

Despite the increased interest in gamification approaches, there is a lack of comparative studies that shed light on the applicability of these approaches in educational contexts. In this explorative study, with an experimental design, university learners ( N = 98) studied a complex process (i.e., how to brew beer) in a 2-hour-long computerized simulation. In the experimental condition, the simulation featured the following game design elements: game goals, increased freedom of choice, points, virtual currency, and praise (i.e., a gamified simulation). These elements were absent in the simulation versions used in the two control conditions. No differences in learning outcomes and intrinsic motivation variables between the gamified simulation and its nongamified versions were observed. The gamified simulation was perceived to be significantly easier than the nongamified versions ([Formula: see text] = 0.10; d = 0.74, 0.42). Of the game elements used in this study, the participants perceived most positively a clear, game-like goal. The findings are consistent with self-determination theory, cognitive-affective theory of learning from media, and cognitive load theory. The findings also support the emerging notion that caution should be applied when using gamification approaches in educational contexts.

There is increased interest in augmenting multimedia instructional materials to elevate learners’ positive affective-motivational states in order to improve learning. However, these efforts have only been partly successful and mediational effects of positive affective-motivational states have not always been established. In this study, university students (N = 65) from the Czech Republic, a country where beer brewing is a source of national pride, were informed that they would either study how to brew beer (high intrinsic motivation condition) or how to prepare a citrate substrate (low intrinsic motivation condition). The 90-min simulation environment used for learning was about beer brewing in both cases, with superficial changes to instructions and graphics to disguise the topic manipulation. Generalized positive affect, overall enjoyment, flow, and learning involvement were higher in the beer brewing condition (Cohen’s d = 0.44–0.87) as were learning gains when measured immediately (retention: d = 0.48; transfer: d = 0.46) and a month later (retention: d = 0.66; transfer: d = 0.62). However, only learning involvement and flow positively mediated the influence of the topic manipulation on immediate learning outcomes; there were no mediation effects on delayed learning outcomes after co-varying out immediate learning. The findings corroborate results from extant studies on the importance of topic interest in learning from instructional texts. They also indicate that affective-motivational mediation is one, but not the only, mechanism by which topic-based intrinsic motivation manipulations influence learning and that induced positive affective-motivational states can be differentially related or unrelated to learning.

Composing instructional texts in multimedia learning materials in a conversational style rather than a formal style can facilitate learning. We investigated whether a specific language/cultural background could present a boundary condition for this effect. In four experiments with a Czech sample (N = 278), we replicated a seminal experiment conducted on a US sample (with a short animation on the topic of lightning formation), which demonstrated a large effect size in favor of the instructional texts in the conversational style. In our four experiments, we varied between two types of audiences (a college and a high school audience) and two types of short animations (the original one and a complementary one). Instructional texts in a conversational style brought no overall advantage for the Czech audience (ηp2 = .00; the high school audience: d = 0.48, 0.22; the college audience: d = −0.45, −0.04). Twenty-nine percent of participants who received the conversational instructional texts expressed explicit reservations regarding the style of the language. In the fifth supplementary experiment, Czech participants (N = 138) had to rate preferences on computer tutor’s printed statements. Direct rather than polite statements were preferred. Limited benefits of conversational/polite instructional texts for Czech learners are probably related to the generally more formal approach to education in the Czech Republic compared to the US schooling system. We also failed to find a link between several affective variables and learning outcomes; with the exception of a relationship of generalized positive affect, levels of flow and perceived difficulty to some of the learning outcomes.
