HASC's mission is to train contractors to stay as safe as possible while working in petrochemical and oil refining facilities. Due to the large number of contractors who enter this workforce every year, HASC provides a six-hour introductory class on safety in the industry called Basic Orientation Plus (BOP).
Although a good model for new field technician training, BOP could be more effective for learners by using more innovative tools, especially those that emphasize spaced practice. In 2020 HASC performed a study on the use of spaced practice opportunities for learners in BOP utilizing a text messaging delivery. This study will focus on a similar study performed in 2021 focused on providing spaced practice using Instagram as the delivery method for BOP learners.
Rationale for the StudyHASC hosts two BOP classes a day with up to 150 learners in each class. These small communities of learners work to pass the BOP exam, a qualifying exam for working within the petrochemical and oil refining industry. These learners spend between six and eight hours in BOP and are allowed to work together during class, reflect together during breaks, and collaborate with the instructor. In essence, they become an organization of learners within the HASC organization for the duration of the training. HASC is working to create a stronger community of learners and on providing an open system within the organization similar to what Morgan (2006) discusses regarding subsystems that spring up within systems and are a smaller part of the whole. Following some of the precepts of Morgan's (2006) writing on organizations as open systems analogy, HASC is hoping to inspire learner's within these learning group subsystems to provide creative content, work together, understand broader concepts, and "influence the nature of their environment" (p. 63). The expected results from providing spaced practice opportunities, and inspiring greater confidence among the learners through an open system, is that learners will have a better opportunity to pass the BOP final exam. Additionally, Morgan (2006) discusses the organizational ecology and the creation of a shared future. In the short term, BOP learners share a common future of finishing the class and passing the final exam. A tool that allows them a more engaging and effective learning technique like spaced practice could help the learners all realize that shared future.
Research Questions and Theoretical Perspective
The 2021 HASC study on spaced practice and Instagram will focus on the use of cognitivism and behaviorism (Kauffeld and Lehmann-Willenbrockand, 2010; Arghode et al. 2017) as a bridge application (Ertmer & Newby, 2013) that will allow for a more open organization among the class community. This will be completed using a mixed qualitative and quantitative research design to answer three primary questions:
1) Do social media interactions for spaced learning provide better opportunities for reflective learning than text-delivered chatbots for BOP learners?
2) Does using Instagram for reflective spaced practice provide a better understanding of BOP concepts than instruction without Instagram practice sessions?
3) Do learners create a more open system within the class by engaging with and creating content via Instagram?
Literature ReviewThere is ample research on the effectiveness of spaced practice on learning. Dempster and Farris (1990) state that it is "ubiquitous in scope" (p. 97) and note that it is a standard within the learning community as a successful tool to impart learning (Dempster & Farris, 1990, and Dempster 1989). Carpenter et al. (2012) state that "any form of spacing – whether it is fixed or expanding - appeared to promote learning" (p. 5) and "in order to promote long-term retention of knowledge, students should receive spaced re-exposure to previously-learned information" (p. 5). Space practice encourages engagement among the class and includes active processing of information, a key, according to Arghode et al. (2017) to cognitivism.
Social media is becoming more universal and natural for workers entering into the petroleum and petrochemical refining industry and more likely to be used for information sharing among this learning cohort (Tran, 2018). According to Hortigüela-Alcalá et al. (2019), these social media platforms allow learners to play an active role in their learning and provides "more collaborative-based methodologies" for learners. Hortigüela-Alcalá et al. (2019) also found that learners who utilized social media as a part of learning not only learned more effectively but were also more motivated to learn. Kunka (2020) found similar greater engagement levels with students who utilized social media as a part of their learning. Al-Bahrani and Patel (2015) reported on many studies that have found positive results for social media in classes but also found evidence that this tool provided opportunities for shy students to interact more. These are all key features of an open and engaging classroom that HASC is trying to promote. According to Arghode et al. (2017) behaviorism's uniqueness lies in "its belief in how learning is achieved based on external stimuli and subsequent response" (p. 595). By applying an external stimuli to our BOP class subsystem HASC hope to change the behavior of the learner, from passive learner to active and engaged.
Many different researchers have studied and analyzed merging social media for engagement and more effective learning with spaced practice. Avila (2021), working with a theoretical design of digital agency, hoped to find evidence that learners would gain confidence working within the class by using a tool they were familiar with. Using a qualitative ethnographic study, Serpagli and Mensah (2021) stated that learners found "Instagram as a classroom tool was "casual" to the students because they were already using it in their daily lives" (p. 295). Swanepoel and Bruwer (2020) found that learners thought Instagram provided greater motivation to accompany lectures, while Nagel et al. (2018) discovered positive results for social media to enhance classroom activities.
These studies show not just the benefits of spaced practice, but also the benefits of Instagram for delivery of this reinforcement tool. In fact, many of the studies selected as a part of this review focused on how social media use could provide more open forms of communication like wikis, story-telling, feedback texts, images with captions for more explanation and the promotion of a more collaborative learning environment (Nagel et al. 2018; Serpagli & Mensah, 2021; Swanepoel & Bruwer, 2020;). As part of HASC's goal is to promote a more open organization/ subsystem where learners can create content, collaborate in class, and develop a richer understanding of the concepts and learning objectives, having tools that promote this type of interaction would help the BOP learners create that type of dynamic.
Research DesignFor this Instagram study, HASC followed the model established in 2020 with the text delivery spaced practice study. HASC used the same questions that were used in 2020 and ran the test with a similar number of classes. HASC also utilized an open question survey to glean reactions from learners who utilized the tool. This design followed many of the best practices found in similar studies such as the Serpagli and Mensah (2021) study which used a qualitative ethnographic methodology and used a similar sampling method that found that Instagram brought "science into the daily lives of digital natives" (p. 288). Making BOP a part of the learners daily lives and actions is a goal of this study. The study on using Instagram to promote blended learning by Swanepoel & Bruwer (2020) was also used as a paradigm for the HASC study as their mixed qualitative and quantitative design found that an "always-on leaner, who thinks about the module outside of the lecture" is a similar goal for promoting the open organization with HASC's BOP classes.
Results and Analysis
In 2020, when HASC delivered spaced practice through text message, 170 learners started the spaced practice test, and 99 learners completed all four modules. Over the course of the study, 205 learners took BOP and had the opportunity to use the spaced practice via text capability. In 2020, 83% of the BOP learners started the spaced practice exercise, and 48% completed the exercises completely.
In 2021, when HASC delivered spaced practice through Instagram, 73 learners started and completed the spaced practice exercises. Over the course of the Instagram test, 534 learners took BOP and had the opportunity to utilize the tool via Instagram. Only 14% of the total learners who took BOP took advantage of the spaced practice exercises.
In a departure from the 2020 study, for the Instagram study there was the addition of several survey questions asked to volunteers after the class. Five learners were interviewed as a part of this study. The interview consisted of both open-ended and multiple-choice questions. Based on the results of the multiple-choice questions, all of the learners surveyed were not new to the Instagram platform, and each of them indicated that they enjoyed the opportunity to answer BOP relevant questions via the application. Additionally, in the open-ended questions, one learner wrote, "it made me learn something that I thought was right but helped me understand better." Another learner wrote, "it helped me study and review information, so if I got it wrong, I could look at it again." Both of these answers tend to reinforce the importance of spaced practice to learning.
In terms of Instagram being easier to utilize because it was provided using a platform the learners were already familiar with, one learner wrote that they liked that it was "user friendly," however another learner wrote, "it would be easier to access if it was provided via text." One of the multiple-choice questions addressed this same questions regarding text delivery vs. Instagram delivery, and the responses were mixed in that 60% of the respondents would have taken the quiz had it been sent via text. To the question of whether or not other social media platforms should be employed, 80% of respondents responded with "yes." The fact that a majority of respondents wanted more social media usage implies that there is a desire among BOP learners for this level of engagement and therefore for more collaboration among learners.
ConclusionThis study found that compared to the text-delivered spaced practice exercises, learners in the BOP course did not utilize the opportunity for spaced practice as much when it was offered on Instagram. Secondly, the overall completion rate, whether via text delivery or Instagram, was lower than might be expected based on the studies used for the literature review. There are several reasons that this might be the case.
When introducing the Instagram exercises, the instructional designer would ask how many people in the class used Instagram regularly. The number of students who self-identified as Instagram users in class was usually about 10% to 20% of the total class population. Based on these rough estimates from the instructional designer, the use of Instagram among BOP learners is not as high as the use of Instagram among the overall population of the US that uses Instagram (Mediakix, 2016). Although it could be that learners were hesitant to self-report their use of Instagram during class, the reason for this under-reporting could also be that the use of Instagram among the primarily working-class laborer that HASC supports is lower than the US average. Further study will have to be completed to answer this specific question.
Additionally, Instagram is a free application. There is no sign-up fee nor ongoing usage fee. Any BOP learner who did not use or have Instagram on their smartphone could have downloaded the application for free to take the spaced practice exercises. One failure of this research design was not asking the learners when we introduced the application how many learners did not have smartphones, which would have been worthwhile to use as a gauge of technological adoption among the BOP learning cohort.
Most of the studies selected as a part of the literature review included subjects who were active students, either in high school or in college. The learners in HASC's BOP classes are, in most cases, not college-educated and are no longer in high school. The motivation that BOP students have is extrinsic rather than intrinsic. Contractors do not attend BOP because they enjoy learning; instead, they attend BOP so that they can work in the industry. The learners' usage of the spaced practice exercises; whether via Instagram or text, was not as high as expected based on the expected rates from the studies included in the literature review. This implies that learners were not overwhelmingly concerned or inspired to take the spaced practice exercises. Again, more study will need to be performed to determine if spaced practice alone is seen as a benefit to the BOP learners.
As to the third research question regarding user created content; there were no BOP learners who interacted, created content, nor posted replies as a part of this Instagram study. Finding ways to encourage more open conversation and exchange of information, both from the HASC instructor to the learners and between learners, is a worthwhile endeavor to help improve collaboration and provide greater reinforcement of learning objectives.
Spaced practice has a deep history of success in assisting learners in retaining learning objectives (Dempster & Farris, 1990; Dempster, 1989; Hintzman, 1974). A platform like Instagram, which has been shown to increase engagement and provide an outlet for collaboration (Prasetyawati & Ardi, 2020; Serpagli & Mensah, 2021; Swanepoel & Bruwer, 2020), combined with spaced practice should lead to both greater engagement and communication between all of the learners and instructors. Using Instagram should have provided a lower barrier to entry and fewer challenges for the learners to use the tool. According to the quantitative data, this did not occur.
Based on the qualitative interviews, those using the spaced practice Instagram tool found it worthwhile and effective. One feature that might help adoption would be if the spaced practice tool was platform agnostic, to ensure that no matter the social media application the BOP learner could use the application they were most comfortable using. As Deed et al. (2014) state in the conclusion of their study on student agency, the "extent of student agency was dependent on their capacity to take responsibility for their own learning" (p. 74). Providing greater student agency through Instagram or other social media tools would provide for greater ownership by the student and a more open subsystem for the BOP class.
Additionally, more tools that use social media should be utilized within BOP and in other training classes that HASC offers. A significant challenge with this research could have been the limited exposure that HASC learners have with using social media for training at HASC. Finding ways to make innovative training tools more ubiquitous, easy to access, a part of the learners' daily lives, a natural behavior to reinforce learning across all courses, will help strengthen HASC's impact on the contractor learning community, and help foster a stronger, open organizations and subsystems among the learners.
