Students’ Situational Interest
Interest is an essential construct that shapes people's lives by affecting their leisure activities or determining their career paths after high school graduation (Harackiewicz & Hulleman, 2010). In educational contexts, when students find a topic or activity interesting, they show more focused attention and increased cognitive functioning, which may lead to a deeper engagement and, finally, to enhanced learning outcomes and a more positive attitude toward the subject matter (Harackiewicz & Hulleman, 2010; Hidi, 2001; Jansen et al., 2016; Köller et al., 2001; Kriegbaum et al., 2018; Mitchell, 1993; Murayama, 2022; Rotgans & Schmidt, 2017b; Trautwein et al., 2006). In a meta-analysis, Schiefele et al. (1992) demonstrated that students’ interest in mathematics was positively associated with their mathematics achievement (r = .32, k = 31, SD = .086).
Interest is commonly described as a positive psychological state that drives individuals to engage with specific content or activities (Ainley & Hidi, 2014; Frenzel et al., 2010; Hidi & Renninger, 2006; Krapp et al., 1992; Schraw & Lehman, 2001). It is considered a "prototypical intrinsic motivational construct" (Harackiewicz & Knogler, 2017, p. 335) that is closely related to a feeling of enjoyment (Jung et al., 2024). In educational contexts, interest is assumed to be specific to a particular subject matter (Schiefele, 1991). Interest can be theoretically and empirically categorized into individual (or personal) interest and situational interest (Mitchell, 1993; Schraw & Lehman, 2001). Individual interest is a relatively long-lasting, enduring disposition toward a particular topic or activity, often resulting from a personal affinity or background knowledge (Hidi & Renninger, 2006). In contrast to individual interest, situational interest is a more transient and context-specific form of interest, often triggered by environmental stimuli or specific learning activities (Schraw & Lehman, 2001).
The relationship between these two ways of conceptualizing interest lies in the genesis of interest. Situational interest can contribute to the development of long-lasting individual interests (e.g., through affective-cognitive synthesis; Hidi & Harackiewicz, 2000). A theoretical framework that demonstrates how situational interest can evolve into individual interest is the four-phase model of interest development proposed by Hidi and Renninger (2006; see also Knogler et al., 2015; Renninger & Su, 2012). The basic assumption in the framework is that interest emerges from an individual's interaction with the environment (Hidi & Renninger, 2006; Krapp, 1999; Krapp et al., 1992; Murayama, 2022). According to the framework, situational interest can be triggered initially by capturing a student's attention via certain stimuli or activities that are novel, surprising, or personally relevant (triggered situational interest). The triggered interest needs to be stabilized through supportive conditions, such as instruction that promotes engagement and provides meaningful tasks (maintained situational interest). With continued exposure and positive experiences, situational interest can transform into emerging individual interest, characterized by a more persistent and deeper engagement (emerging individual interest), and finally develop into well-developed individual interest, where students show consistent and self-motivated engagement with the subject matter (well-developed individual interest).
Decades of research have shown that students' interest tends to wane as they progress through secondary school (Eccles & Midgley, 1989; Kunter et al., 2007; Scherrer et al., 2020; Wigfield et al., 2006). For instance, using longitudinal data from N = 3,193 students (51% female), Frenzel et al. (2010) showed a downward trend in students' interest in mathematics from Grades 5 to 9. Mathematics appears to be particularly vulnerable to such waning interest (Jacobs et al., 2002; Köller et al., 2001; Watt, 2004; for a recent example, see Lehikoinen et al., 2024), as this decline has been more pronounced in mathematics than in other subjects (Gottfried et al., 2001; Hedelin & Sjöberg, 1989).
As different instructional arrangements (i.e., teaching "situations") substantially impact students' state interest (Knogler et al., 2015), situational interest is a crucial factor in students’ learning (especially for unmotivated students; Hidi & Harackiewicz, 2000). Teachers cannot directly influence students' individual interests (i.e., students’ preexisting interests), but the situational interest generated by instruction-related factors is of paramount concern. That is, teachers can use the mechanisms responsible for the evolution of interest as it develops from situational into individual interest to promote interest or to compensate for the decline (i.e., hoping that a classroom rich in situational interest can alter an individual’s personal interest in the subject over time; Mitchell, 1993). In addition to factors related to a stimulating environment, such as stimulating tasks/problems (Harackiewicz et al., 2016; Rotgans & Schmidt, 2017a), or characteristics of the teachers, such as their enthusiasm (Jung et al., 2024), situational interest may be promoted if teaching is designed to avoid the characteristics that have been identified as responsible for declining interest. The decline in students' interest across secondary school can be attributed to different factors. For instance, in mathematics, studies have emphasized that students develop little interest because they have difficulties understanding complex concepts and are thereby overburdened or bored, as they perceive no utility or a lack of relevance in the content (Frenzel et al., 2010). Boredom is especially likely in mathematics, which has been documented for decades (Mitchell, 1993). Moreover, it is well known that students often struggle to maintain their initial enthusiasm and curiosity in mathematics (Frenzel et al., 2010), and mathematics appears to be particularly uninteresting to students, especially during puberty (Frenzel et al., 2010; Hoffmann et al., 1998).
Importantly, several recent studies that have used experience sampling methodology to study students' situational interest have shown that students' interest varies greatly from lesson to lesson. Most of the variance can be explained by intraindividual differences between students (Flunger et al., 2022; Järvinen et al., 2022; Martin et al., 2015; Parrisius et al., 2022; Patall et al., 2016). These findings have crucial implications: First, teachers are confronted with considerable heterogeneity in students' interests, and second, students' interests are sensitive to the nature of teaching during a lesson. The study by Flunger et al. (2022) showed that lesson-specific autonomy support by teachers was associated with students' engagement and motivation. Similarly, Heemskerk and Malmberg (2020) showed that student engagement was higher during individual tasks, teacher-supported tasks, and assessments than teacher-led instruction. Most relevant for the present study is Patall et al.’s (2018) finding that students became disengaged in lessons when the previous task was too difficult.
In summary, students are less likely to develop situational interest if they are bored (e.g., because the lesson is too easy) or overwhelmed (e.g., because the lesson is too complex) or if the teacher does not help students recognize why the learning material has utility for them (Ainley, 2006). Therefore, educators must balance the difficulty of instructional materials and activities to ensure they are appropriately challenging yet accessible. The extent to which a lesson can avoid underchallenging or overchallenging students and is therefore not perceived as either boring or overwhelming is crucial for arousing and maintaining students’ interest in teaching situations. Such teaching is referred to as adaptive teaching.
Technology-Enhanced, Adaptive Teaching as a Key Aspect for Promoting Students' Situational Interest
The idea of adapting teaching to students' differences to personalize students' learning experiences has a long history (Corno, 2008; Dockterman, 2018). It is one of the few teaching principles that has "withstood the dual tests of time and directed research" (Corno, 1995, p. 98). In their study on aptitude-treatment interaction (ATI), Cronbach and Snow (1977) showed that the effectiveness of instructional treatments depends on students' individual differences. More specifically, they found that lower ability students benefit more from teacher guidance than higher ability students do (Cronbach & Snow, 1977). This finding has been replicated numerous times and is now known as the expertise reversal effect (Kalyuga, 2007). The concept of adaptive teaching thus suggests that the level of guidance needs to be adapted to students' level of understanding so that each student can learn in their zone of proximal development (Corno, 2008; Vygotsky, 1979). Importantly, this concept applies to inter- and intraindividual differences: Low-achieving students need more structure and guidance from teachers than stronger students who are better prepared to self-regulate their learning processes. As students become more competent over time, the teacher must gradually decrease their guidance and hand over responsibility to the students to promote self-regulated learning. To adapt their teaching, teachers need to continuously assess students' levels of understanding.
The most visible manifestation of adaptive teaching can be seen in adaptations of various instructional features—such as teaching methods, materials, tasks, feedback, or explanations—to meet the specific needs of individual students or groups of students with similar needs. According to Corno and Snow (1986), adaptations can vary along a continuum from the macro-level to the micro-level. Whereas macro-adaptations refer to planned and longer term instructional adjustments for groups of students with similar competencies, micro-adaptations refer to spontaneous adjustments a teacher makes in response to individual students "on the fly" (Corno, 2008). Therefore, teachers must be flexible as they adapt their instruction to support various learners (Parsons et al., 2018).
It is a major challenge for teachers to implement adaptive teaching and get all students interested in the lessons, as not all students “have interests that are easily adaptable to school settings and academic learning” (Hidi & Harackiewicz, 2000, p. 157). Being flexible and becoming an “adaptive expert” (Darling-Hammond et al., 2005) is demanding for teachers, as adaptive teaching (in mathematics) requires teachers to reflect on students’ cognition, motivation, emotions, and learning trajectories and to provide feedback, modify curricular materials, and orchestrate classroom discourse (Gallagher et al., 2022; Schmid et al., 2022). Thus, adaptive teaching has often remained a theoretical ideal for decades, but its practical implementation has repeatedly failed (many teachers do not teach adaptively; Ankrum et al., 2020; Hardy et al., 2022; Pozas et al., 2020; Vaughn, 2019).
Against this backdrop, technology has the potential to support teachers in facilitating adaptive teaching (especially micro-adaptation; Aleven et al., 2017; Scheiter, 2017; Schmid et al., 2022; Xie et al., 2019), particularly in mathematics (Zhang et al., 2020). For instance, technology helps teachers scaffold students as the students solve problems (e.g., by using simulations or virtual reality to visually represent complex content; Kim & Hannafin, 2011; Puntambekar, 2022). This kind of scaffolding is especially suitable for supporting students’ interests (Harackiewicz & Knogler, 2017) or for performing formative assessments of students’ learning and providing feedback continuously by automating these processes (Mavroudi et al., 2018; Van Der Kleij & Adie, 2018). Moreover, technology can support adaptive collaboration between students through intelligent tutoring technology (Diziol et al., 2010). Thus, technology has the potential to help teachers provide adaptive instruction, for example, by avoiding simple tasks that lead to disengagement and boredom (Blayney et al., 2016). In support of this claim, in the International Computer and Information Literacy Study 2018, 87% of teachers agreed that technology helps students work at the level that is appropriate for their learning needs, and 91% said that technology helps students develop greater interest in learning (Fraillon et al., 2020).
Providing support for the potential benefits of technology for adaptive teaching comes from an empirical study by Walkington (2013) who investigated the effectiveness of using adaptive learning technologies to personalize mathematics (i.e., algebra) instruction to students' interests (145 ninth-graders) with an intelligent tutoring system in an experimental design. She found that the personalization had a particularly strong impact on students who were struggling with algebra. This finding suggests that technology-based adaptive teaching (i.e., adapted to students' interests) is particularly beneficial for students who struggle with mathematics, as grounding abstract mathematical concepts in contexts relevant to students' interests can make the concepts easier to understand and easier to learn.
Furthermore, technology has been found to have only small effects on students' achievement (Tamim et al., 2011; Zheng et al., 2016) and students’ motivation and attitudes (e.g., on students’ motivation to do mathematics: d = 0.30, Higgins et al., 2019; on students’ attitudes toward mathematics: g = .045, Hillmayr et al., 2020). The key to promoting student learning is not just that technology is used but how technology is implemented into teaching (Fütterer et al., 2022; Fütterer, Hoch, et al., 2023; Sailer et al., 2024), a finding that again applies in particular to adaptive learning systems (Keuning & Van Geel, 2021). In this vein, Sibley et al. (2024) showed that technology has great potential to support adaptive teaching, but its effectiveness depends on its thoughtful integration into teachers’ classroom instruction (i.e., the overuse of technology might overwhelm students). Moreover, Colliot et al. (2024) showed in an experimental study that it was not the use of tablet computers that improved students' performance but the personalized feedback that the intelligent tutoring system provided (see also the review by Maier & Klotz, 2022). Similar mechanisms can be assumed for students’ interests, where there is a need to distinguish between two different mechanisms behind the effect of technology on learning, particularly students' interests. The first effect is a direct effect of technology on students’ interest, known as the novelty effect, which is thought to be short-term but not sustainable. The novelty effect can be defined as "an improvement in learning when a new technology is introduced, attributable to increased interest in the new technology, that tends to diminish as students become more familiar with it" (Metcalf et al., 2019, p. 115). Indeed, computers have been found to trigger situational interest (Lepper & Malone, 1987) only in the short term. In a recent study, Jeno et al. (2019) found that whereas the novelty of educational technology attracts initial attention and interest, it does not sustain motivation or improve learning outcomes over time.
Such situations can be assigned to the first phase of interest genesis (triggered situational interest), as situational interest in this case is triggered by a sudden change in the learning environment (the introduction of [new] technology) and the immediate affective and emotional responses of the students (see, Hidi, 1990; Hidi & Harackiewicz, 2000; Hidi & Renninger, 2006; Hulleman et al., 2010).
However, as computers are usually not enough to maintain students’ interest in mathematics by themselves, the triggered interest must be stabilized through supportive conditions such as a change in instruction (maintained situational interest). If technology is used in the manner described above so that instructional methods change and the quality of teaching increases (i.e., it becomes more effective in generating learning), for example, by becoming more adaptive, then there is an indirect effect of technology on student learning, which is assumed to have a lasting effect (Clark, 1983, 1985). Such situations can be assigned to the second phase of interest genesis (maintained situational interest), where interest has the chance to stabilize. In their review, Zhang et al. (2020) found that technology-supported personalized learning was positively associated with students’ academic outcomes, attitudes toward learning, and engagement (see also Major et al., 2021).
Research Questions and Hypotheses
As situational interest has been shown to decline during secondary school, especially in mathematics, it is particularly important to find ways to promote and maintain students’ situational interest during this time. Adaptive teaching has proven to be an effective way to increase (situational) interest. Additionally, technology offers great potential for the implementation of adaptive teaching. Thus, in this study, we investigated direct effects of technology on students' interest in mathematics and indirect effects mediated by students’ perceptions of the extent to which digital instruction is adaptive by addressing the following research questions (RQ) and testing the associated hypotheses (H):
(RQ1) How does 1:1 technology (i.e., tablet computers for students) affect students' situational interest in mathematics (at the student and class levels)?
On the basis of previous research (e.g., Higgins et al., 2019; Tamim et al., 2011; Zheng et al., 2016) and due to potential corresponding novelty effects, we expected small positive effects (d ≤ 0.35) of 1:1 tablet computers on students' situational interest in mathematics at Level 1 (students; H1.1) and Level 2 (classes; H1.2).
(RQ2) How is student-perceived adaptive teaching in mathematics (at the student and class levels) associated with students' situational interest in mathematics (at the student and class levels)?
The more students perceive teaching in mathematics as adaptive, the higher students' situational interest in mathematics at Level 1 (students; H2.1) and Level 2 (classes; H2.2).
(RQ3) Does student-perceived adaptive teaching in mathematics (at the student and class levels) mediate the effect of 1:1 technology (i.e., tablet computers for students) on students' situational interest in mathematics (at the student and class levels)?
Student-perceived adaptive teaching in mathematics at least partially mediates the effect of 1:1 tablet computers on students' situational interest in mathematics at Level 1 (students; H3.1) and Level 2 (classes; H3.2). For all hypotheses referring to effects at Level 1 and Level 2, we expected the same direction but weaker effects at the class level (Level 2) than at the student level (Level 1).
