A photographic activity schedule is a set of pictures or words that prompts an individual to engage in a sequence of specific behaviors (McClannahan & Krantz, 1999). Researchers have shown activity schedules to be an effective way to teach individuals with disabilities a variety of skills, including independent completion of work tasks (Carson, Gast, & Ayres, 2008), independent solitary play for children with autism (MacDuff, Krantz, & McClannahan, 1993), and both simple and complex social play for children with autism (Akers, Higbee, Gerencser, & Pellegrino, 2018; Betz, Higbee, & Reagon, 2008; Brodhead, Higbee, Pollard, Akers, & Gerencser, 2014). These studies demonstrate that activity schedules promote independence, increase learner engagement with appropriate activities, and decrease reliance on prompts. Therefore, these tools are ideally suited for situations, such as the current COVID-19 crisis, where access to direct, professional-led learning may be reduced and clients may be provided with longer periods of “downtime” than under typical circumstances.

Activity schedules are an attractive tool for promoting independence not only because of their effectiveness but also because of the broad range of individuals with whom they can be used and the wide array of skills they can be used to promote. They require relatively few prerequisite skills and conditions in order to be effective (e.g., picture-object correspondence, acceptance of physical prompts, identified reinforcers) and can be used to teach sequences of behavior as simple as independent play sequences (MacDuff et al., 1993) and as complex as group social games such as hide-and-seek (Akers et al., 2018). Importantly, researchers have demonstrated that parents can be taught, via technology, to implement activity schedule teaching procedures with high degrees of fidelity (Gerencser, Higbee, Akers, & Contreras, 2017).

To date, most activity schedules used in published studies have been composed of three-ring binders with pictures attached to individual pages or strips of pictures on a single page. Although inexpensive, binder- or paper-based schedules may have some disadvantages, such as being cumbersome to transport (Carlile, Reeve, Reeve, & DeBar, 2013) and, perhaps more importantly, potentially socially stigmatizing, as same-aged peers would likely not be carrying around books during activities (Giles & Markham, 2017).

Given technological advances that have made portable electronic devices, such as tablet computers, more readily available to teachers and families of individuals with disabilities, there may be advantages to using digital schedules that could be displayed on these devices. First, scanned or photographic images of activities could be easily moved around within activity schedules, reducing the cost and effort of printing and laminating images for inclusion in binder-based or single-page printed schedules. Second, digital schedules could easily be shared across multiple devices. For example, copies of the schedule could be updated by a teacher or therapist and then e-mailed to a parent for use at home. Finally, tablet computers are now ubiquitous in school, work, and home settings, thus reducing potential stigmatization for digital activity schedule users.

Multiple researchers have investigated the effectiveness of various forms of digital activity schedules delivered on electronic devices, including computers running Microsoft PowerPoint (Rehfeldt, Kinney, Root, & Stromer, 2004), iPods to increase on-task behavior (Carlile et al., 2013), video clips to increase dramatic play (Dauphin, Kinney, & Stromer, 2004), iPads to increase time on task and decrease transition time during centers (Gourwitz, 2014), and iPads to promote completion of leisure activities (Giles & Markham, 2017). One published study has also indicated that, for some participants, digital activity schedules may be preferred over binder-based schedules (Giles & Markham, 2017). Although further research on the use of digital activity schedules is certainly warranted, a sufficient body of research exists to demonstrate the potential benefits of this technology. Given the portability of digital activity schedules and the potential for behavior analysts to be able to design digital activity schedules and transmit them electronically to parents or caregivers for use with their children at home, we believe that they are ideally suited to the current therapeutic environment caused by the COVID-19 pandemic, which limits direct contact between behavior analysts and the clients and families with whom they work. Thus, the purpose of this article is to provide a detailed task analysis that both behavior analysts and parents can use to create and modify digital activity schedules using Google Slides, a freely available, web-based program that works on a variety of digital devices and platforms.

Brief Activity Schedule Primer

Although detailed descriptions of how to create and build independence using activity schedules are available elsewhere (e.g., Higbee & Brodhead, 2016; Higbee & Sellers, 2017; McClannahan & Krantz, 1999), a brief summary of how to select activities for inclusion in a digital activity schedule and standard prompting/teaching techniques is included here. We refer the reader to the cited papers for more detailed descriptions and instructions.

Selecting Activities and Arranging the Environment

Specific activities to be included in a beginning activity schedule, including a digital one, should be moderately preferred, close-ended (i.e., have a clear beginning and end), relatively brief, and already independently performed by the learner, as the focus during initial activity schedule training is on how to follow the schedule rather than on the activities themselves (Higbee & Sellers, 2017). Beginning activity schedules are usually composed of at least two to three activity pages plus a terminal reinforcer page (typically a small amount of a preferred edible) at the end. Additional activities can be added as the learner demonstrates mastery of the schedule to form progressively longer response chains. The sequence of activities should be changed frequently to ensure that the learner’s behavior comes under the control of the pictures displayed as opposed to becoming a sequence of rote behaviors under proprioceptor control of sensations repeated in a performance chain.

Activity schedules can be used in multiple environments. However, beginning play/leisure activity schedules often are used at a table or desk that is large enough to both hold the schedule and provide enough room to complete the activities (the floor could also be used in the absence of a desk or table). Activity materials are typically placed on a shelf near the desk/table. They could also be placed directly on the table if it is large enough to hold all materials and still have a clear work space to complete activities. Alternatively, materials could be placed on the floor near the table. When learners are first beginning to use activity schedules, the idea is to have the materials close at hand to reduce travel time and the potential for distraction. Once learners have mastered the basic components of activity schedule following, materials can be placed in their natural locations.

Sequence of Activity Schedule Following

Learners are taught, through a procedure called “graduated guidance,” described in the next section on prompting procedures, to follow the activity schedule. The following sequence of behaviors constitutes “following the schedule”:

  1. 1.

    Retrieve the schedule (obtain the tablet or other digital device) and place it on the table/floor where activities will be completed.

  2. 2.

    Open the schedule file/program (Steps 1 and 2 may be completed by a parent or teacher for a digital schedule, depending on the learner’s level of familiarity with the technology).

  3. 3.

    Touch the picture of the activity (an observing response).

  4. 4.

    Obtain the materials necessary for completing the activity (e.g., retrieve the pictured puzzle from a shelf).

  5. 5.

    Complete the activity.

  6. 6.

    Return the materials back to their original location.

  7. 7.

    “Turn the page” on the digital schedule to display the next activity by touching or clicking on the arrow in the bottom-right corner of the screen.

  8. 8.

    Repeat Steps 3–7 until reaching the terminal reinforcer page and consuming the reinforcer.

  9. 9.

    Return the digital device to its original location or close the program.

Prompting Procedures and Error Correction

In an effort to reduce dependence on adult-provided verbal prompts and instructions, learners are taught to follow activity schedules exclusively via physical prompts delivered from behind the learner, so as not to block the learner’s view of the relevant visual stimuli that should control their behavior (McClannahan & Krantz, 1999). The only verbal instruction given to the learner should be the initial instruction to begin completing the schedule (e.g., “It’s time to do your activity schedule. Here you go!”). After that, the person assisting the learner to follow the schedule should not provide any additional verbal instructions, verbal prompts, or conversation until the schedule is completed (unless one of the included activities is a social activity during which verbal interaction would be appropriate). The amount of physical prompting provided will depend on each individual learner’s abilities but will often begin with hand-over-hand guidance that should be provided in a way that allows the learner to complete the schedule with as few errors as possible. This physical guidance should be faded as quickly as possible to avoid prompt dependence. A typical fading sequence would begin with hand-over-hand guidance that is progressively faded to physical prompts at the wrist, forearm, elbow, and shoulder, followed by gradually increased physical distance between the prompter and the learner. We have found that light physical prompts from behind at the shoulders are particularly effective for guiding learners back and forth between the schedule and the activity materials. Fading can take place dynamically within sessions or can be scripted across sessions. One practical method for prompt fading that has been particularly useful when parents are the primary implementers is that used by Gerencser et al. (2017), where test sessions are periodically run using a 5-s prompt delay procedure to determine the steps a learner can complete independently. Prompts that the learner needed to complete the task are recorded on a data sheet, which then serves as a teaching guide for sessions until the next test session is conducted (see the Appendix, Fig. 28, for a sample data sheet). Behavior analysts who have the capacity to view sessions live through videoconference technology could also provide parents with fading suggestions in real time.

When learners make errors, the type of error will determine how the implementer/prompter should respond. If the learner begins to drift off task or begins to engage in stereotypy with schedule materials, the implementer/prompter should simply interrupt this behavior and physically redirect the learner to complete the activity correctly. However, if the learner obtains the incorrect materials after touching the picture representing those materials, he or she should be redirected back to the schedule, physically prompted to touch the picture of the materials again, and physically guided to obtain the correct materials. This helps ensure that learner behavior comes under the control of the schedule.

Advanced Activity Schedule Components

Once learners have mastered following basic activity schedules with brief, close-ended activities, more complex activities can be introduced. For example, implementers can add choice pages in which the learner can select from two or more available activities. On a close-ended activity schedule that a learner previously mastered, choice pages could be added to the schedule to replace one or more of the close-ended activities. Learners can also be taught to set and respond to digital timers using visual cues in order to include open-ended activities in the digital schedule. Red circles representing the number of minutes for the activity and a green circle representing the start button are placed below the picture of the open-ended activity. The minute button on the digital timer is also colored red and the start/stop button colored green. The learner is physically prompted to touch each circle below the picture and the corresponding colored button on the timer to set and start the timer. Responding to these more complex activity schedule pages can often be taught via graduated guidance within activity schedule sessions. If a learner requires more practice, modeling and teaching sessions with timers and choice pages could occur outside of activity schedule sessions (Higbee & Sellers, 2017; McClannahan & Krantz, 1999).

Data Collection

Learner performance can be measured by scoring steps from the schedule-following sequence that were performed independently by the learner. A sample data sheet is included in the Appendix, Fig. 28. Whereas collecting data during each teaching session would be ideal during the initial stages of learning, Gerencser et al. (2017) suggest using test sessions that may provide sufficient data to make decisions about prompt levels. An example of the data sheet that is similar to the one used by Gerencser et al. is provided in the Appendix, Fig. 29. Also, when parents are implementing activity schedules, behavior analysts could score performance viewed live through videoconferencing technology or via recorded sessions sent electronically by parents.

  22. 22.

    After the timer video page, create a blank slide to continue making the schedule.

    1. a.

      To finish the schedule, see the section “Creating a New Schedule/Modifying the Schedule Template.”

  23. 23.

    Go to the Present icon (Fig. 12), located in the top-right corner of the toolbar, to view and navigate through the timed activity slides.

    1. a.

      Navigate through the presentation by clicking on the timer dots in sequence and the “NEXT” arrow. Each click should advance to the next slide in the sequence.

      1. i.

        If the slides do not advance correctly, check the links by clicking on the linked object. When clicked on, each linked object should display a white link bar below with the words “Next Slide.” If the slide linked to the object is incorrect (or missing), click “Remove link” and return to the step corresponding to the specific object:

        1. 1)

          Red dot: Step 10 in the section “Creating Navigation for a 3-Min Timer Page”

        2. 2)

          Green dot: Step 13 in the section “Creating Navigation for a 3-Min Timer Page”

        3. 3)

          Next arrow: Step 21 in the section “Creating Navigation for a 3-Min Timer Page”

    2. b.

      After all transitions are working correctly in sequence, restart the slideshow. Check that no other transitions occur when clicking elsewhere on the screen (anywhere other than the linked objects).

      1. i.

        If transitions occur, check the following:

        1. 1)

          Ensure that the transparent rectangle is linked correctly. If it is not, return to Step 2 in the section “Creating Navigation for a 3-Min Timer Page.”

        2. 2)

          If an incorrect object is creating a transition, exit the slideshow and navigate to the slide with that object. Right-click on the object, select “Order,” and then “Send to back.”

Creating a New Schedule/Modifying the Schedule Template

To create a new schedule, copy and paste the template slide sets into a new Google Slides presentation. The template sequences will maintain links and other properties. For example, to create one choice activity, copy all five slides of the choice page. This task analysis will assist in creating a template that clinicians can then use to create client-specific schedules. Each schedule should end with a terminal reinforcer that is linked to a blank page, signaling the end of the schedule (see the Appendix, Fig. 30). To replace pictures in any of the pages, select the large transparent rectangle and move it out of the way. Then edit or replace pictures and place the large transparent rectangle back in place. To test and ensure all pages and features are working correctly, we suggest selecting the Present icon (Fig. 12) to navigate and interact with the slides as the client would to check for errors. To assist with following the activity schedule template sequence, we provide a flowchart example in the Appendix, Fig. 30.

Sharing Schedules With Families and Clients

There are various options for sharing activity schedule files with caregivers and clients. One way is to send the caregivers a link to the activity schedule file. To create a link, select the yellow “Share” button (Fig. 27) in the top-right corner. A pop-up menu will appear that provides sharing options, including view-only or editable access. Select “Get shareable link” and then e-mail this link to the family/client. Other examples of how to share the activity schedule include creating a Google Drive folder with multiple schedule variations or sharing it with other instructional materials using Google Classroom. For all sharing options, learners will need to view the activity schedules in the Present form or the slideshow view. To access the presentation on mobile devices or tablets, they will need to download the Google Slides app.

Discussion

Researchers have demonstrated that photographic activity schedules can be an effective tool to promote independence and reduce the need for adult prompts across a variety of behaviors and for many different types of learners. Whereas much of this body of research has investigated the use of binder-based or single-page paper activity schedules, in recent years, researchers have demonstrated that technology-based digital schedules can also be effective and, in some circumstances, preferred by learners (Giles & Markham, 2017). Digital activity schedules have multiple potential advantages that make them well suited to situations such as the current COVID-19 crisis, during which face-to-face contact between behavior analysts and their clients and families may be reduced or eliminated. Another possible advantage includes the relative ease with which they can be modified and the potential for behavior analysts to create and disseminate digital activity schedules electronically. The task analysis included in this article may be a useful tool as behavior analysts create and disseminate digital activity schedules.
