Learning analytics to unveil learning strategies in a flipped classroom
Summary (4 min read)
1. Introduction
- The educational research community offers a diversity of interpretations on what constitutes a learning strategy.
- Husman, & Dierking (2000, p. 227) suggesting that a learning strategy includes "any thoughts, behaviors, beliefs or emotions that facilitate the acquisition, understanding or later transfer of new knowledge and skills".the authors.
- The authors consider students' learning strategies as latent constructs that cannot be directly observed in the collected traces, but have to be mined/detected using appropriate analytical methods and techniques.
- The authors make a combined use of exploratory sequence analysis and agglomerative hierarchical clustering to detect patterns in student behaviour that are indicative of the adopted learning strategies.
1.1 Active learning and Flipped learning
- This model of active learning requires students to be self-regulated learners in order to undertake and complete the preparatory activities (Lai & Hwang, 2016; Mason et al., 2013; Sletten, 2015) .
- Many students have underdeveloped self-regulation skills and need support and scaffolding to manage their learning in less familiar and more intensive settings that often characterize FL designs.
- To address this need, the FL design examined in this paper has a well-defined structure that is consistent throughout the entire course duration (see Section 2.1).
1.2 Learning strategies and Self-regulated learning
- The capacity of a student to choose and adapt their learning strategy in accordance with the requirements of the learning setting is a key self-regulatory skill (Winne, 2006) .
- Furthermore, previous research has shown that learners are not accurate reporters of how they study and what strategies they apply (Zhou & Winne, 2012) .
- According to Winne, to improve learning, students "might profit from (a) feedback that accurately represents how they actually studied and (b) information about tactics and strategies that might be more effective than those they actually used" (Winne, 2013, p.387) .
- This approach would be better complemented by, or substituted with, digital learning traces (Winne, 2013) .
1.4 Learning strategies and academic performance in flipped classroom
- The above given considerations suggest that a FL setting can both positively and negatively (far transfer) affect a student's selection and regulation of learning strategies, and consequently, their academic performance.
- Previous research has shown that when students manage to quickly adjust to the FL model (i.e., resolve the transfer problem), their academic achievements are comparable to or better than that of students attending traditional lecturing model (Mason et al., 2013; McLaughlin et al., 2013) .
- It has not been sufficiently explored how regulation of pre-class activities affect the overall course performance.
2.1 Study context
- Students were provided with real-time feedback on their level of engagement with the preparation activities and their activity scores via an analytics dashboard (Anonymous, 2016a) .
- Through the dashboard, students could monitor their engagement with the video resources, success in answering MCQs that followed the videos, and MCQs that were embedded in the course related documents, as well as the percentage of correctly solved problem sequences.
- Next to the students' personal scores, the dashboard displayed the overall class scores, thus allowing for social comparison.
- The displayed data was updated every 15 minutes, and the magnitudes were reset each week.
2.2 Learning traces
- To gain an insight into the general patterns of learning sessions of the two student groups, the authors removed the outliers.
- In particular, the authors removed overly short sequences, i.e., those comprising of only one event, as well as those that were overly long, i.e., those that were above the 95 th percentile in terms of the number of events.
- After pruning the outliers, the sizes of the two groups were: 786 sequences for the students with the scores above the 90 th percentile, and 684 sequences for the group with scores below the 25 th percentile.
2.3.2 Clustering
- Kruskal Wallis tests followed by Mann Whitney U tests were used to compare the resulting student clusters based on the midterm and final exam scores.
- False Discovery Rate (FDR) was used as a recommended correction for preventing alpha inflation when doing multiple tests (Cramer et al., 2015) .
3.1 Exploratory sequence analysis
- The figures suggest that there is a considerable difference in the distribution of learning actions along learning sequences between the two examined groups.
- High performing students were observed to be giving roughly equal attention to all types of actions throughout their learning sessions.
- In contrast, their lower performing peers were almost exclusively focused on the summative assessment tasks.
- This initial insight suggested that further analysis of students' learning sequences might lead to the identification of patterns in students' learning behaviour, potentially indicative of the adopted learning strategies.
- Learning action abbreviations are outlined in the figure legend and briefly explained in Table 1 .
3.2 Clusters of learning sequences as manifestations of student learning strategies
- Formative assessment actions are also present though they are gradually and mostly towards the end of the sessions substituted by summative assessment actions.
- These seem to be sessions where students were primarily watching videos, then doing the follow-up multiple-choice questions, and finally trying the exercises.
4. Discussion
- An important practical implication of the presented findings is that instructors should occasionally, and especially after the midterm, remind their students about the importance of choosing effective learning strategies, particularly those strategies that rely on active engagement with the learning resources (e.g., different forms of formative assessment).
- To assure the students' attentiveness to such recommendations, instructors should make the students aware of the value and relevance of the recommended strategies for both learning and academic achievement.
- Furthermore, learning strategies are skills, and as all skills they have to be practiced to develop proficiency (Ericsson, Krampe, & Tesch-Romer, 1993; Winne, 2013) .
- Hence, the instructors should consider altering the learning design, in particular the preparation part of the FL design, to scaffold the development of the desired learning strategies.
4.2 RQ2: Association between learning strategies and course performance
- This finding is also consistent with empirical findings of research studies that examined students' approaches to learning and how these approaches impact academic performance.
- Three approaches to learning have been recognized (Biggs, 2012) : i) deep approach, characterized by critical evaluation and syntheses of information, and driven by intrinsic motivation; ii) surface approach, dominated by shallow cognitive strategies and associated with extrinsic motivation; and iii) strategic approach, which assumes alterations between deep and surface approaches, depending on the characteristics of the task at hand.
- Learning strategies practiced by students from the Intensive group (cluster 1) might be considered as indicative of deep approach; clusters 2 and 3 gather strategic learners, whereas the Selective and Highly selective groups seem to be practicing surface approach to learning.
- Course performance of the five clusters is consistent with the performance levels characterizing the three learning approaches.
- Specifically, meta-analysis by Richardson, Abraham, & Bond (2012) demonstrated positive, though small, correlations between students' performance and both deep and strategic approaches to learning, whereas surface approach was found to be negatively correlated with academic performance.
4.3 Limitations and future research
- Collection of data required for identifying students' goal orientation is not straightforward.
- Traditional self-report measures are not capable of capturing the dynamics of students' goals (Zhou & Winne, 2012) , which, although generally stable, can change along with changes in learning tasks (Fryer & Elliot, 2007) .
- In addition, the ability of students to give valid and objective reports on their goal orientations is questionable (Richardson, 2004) .
- Hence there is a need to extend learning environment with instruments that would allow for seamless and unobtrusive collection of data about the dynamics of students' goal orientation.
- An illustrative example is an annotation tool that allows students to associate selected pieces of content with one or more tags (from a predefined tags collection) reflective of their goal orientations (Zhou & Winne, 2012) .
5. Conclusion
- To inform the instructor on whether the deployed FL design was effective in sustaining student engagement and preparing them for active participation in the class (i.e., face-toface session).
- To provide grounds for selective/adaptive inclusion of scaffolds (e.g., hints, guidelines) to help students improve their learning behavior.
- To make students aware of their learning strategies, and how those strategies compare to the strategies of well performing peers.
- Students in a FL setting often require more awareness of their learning process than students in more traditional settings (Frederickson, Reed, & Clifford, 2005) ; they need to reflect on their learning activities in order to properly connect them with the course materials and requirements, and make necessary adjustments in their learning approach (Strayer, 2012) .
