      <abstract>
        <p>The paper regards an experimental study of an instructional design (ID) model applied in the routines of a digital learning company for content production and course design. Given the complexity of adult learning, the study tried to identify an operative model that could support production process and at the same time ensure rich and engaging learning experiences. The model guarantees the possibility to evaluate learning objectives achievement of through the expression of the target knowledge/skills. Therefore, the ID model can be applied to both mandatory, self-enrolled and professional paths (in up-skilling and re-skilling courses). The development of the model is based on the four-component instructional design (4C-ID) that represents the main structure for the design. The paper presents a practical application of this model in a digital Italian company (Piazza Copernico srl) and explains the preliminary version of the model for future exploitations.</p>

      <title>1. Introduction</title>
      <p>The design of a course is crucial process that includes different figures, from professors to lecturers,
from company trainers to instructional designers. This task is the fundamental stage for the success of
the teaching/learning practices, both in the face-to-face and in online modalities.</p>
      <p>
        In the last years, online courses became even more popular, and their success is highly increased
during the global pandemic [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. The need of the teaching institutions to provide courses using digital
tools boosted a rethinking and recovering of solid pedagogies. In many cases, courses tried to propose
a blended nature [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], trying to maintain a non-digital component. This process pervades learning
institutions of different field, from the universities [
        <xref ref-type="bibr" rid="ref3 ref4">3,4</xref>
        ] to the training in companies [
        <xref ref-type="bibr" rid="ref5 ref6">5,6</xref>
        ].
      </p>
      <p>
        For a course design is important to guarantee the balance between two different learning activities:
declarative learning and procedural learning [
        <xref ref-type="bibr" rid="ref7 ref8">7,8</xref>
        ]. The declarative learning belongs to all the learning
activities that involves the students with books, videos, slides, presentations that are shown to them. In
this case, the students learn from existing contents that could be shown with different modalities and
tools. Students has the task to acquire the knowledge, with a transfer from the teacher (and the media
s/he uses) to the student. The procedural learning requires a more active role for the students. The
learner applies the acquired knowledge by a practical and laboratorial activities, in a learning by doing
process. The main learning process of procedural knowledge is firstly knowing its associated
declarative knowledge, and then knowing how to enact the skill via practice [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. The procedural learning
acquisition, involving a practical and active role require higher cognitive skills than declarative learning
[
        <xref ref-type="bibr" rid="ref10">10</xref>
        ].
      </p>
      <p>When a instructional designer is developing a course should balance the two different learning
modalities and this task is even more difficult when learning goes online, because procedural learning
could be very difficult to be included.</p>
      <p>
        Rooted instructional design methodologies are still present, in order to provide a clear direction in
the course design. A methodological approach is represented by the Complex Learning, that is the
integration of knowledge and attitudes finalized to the management to different skills [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. The complex
learning aimed at the training of complex skills and professional competencies. This approach is used
for designing learning programs that cover a relevant span of time. The goal of the instructional
designers is to achieve the learning transfer from the theoretical to the practical aspects. The results of
these processes are unpredictable and provide a dynamic interaction. Nevertheless, this process could
be managed applying the complex learning skills methodologies. In this view, the whole learning
process is not a simple series of different learning practices but represents a continuous and fluid setting
[
        <xref ref-type="bibr" rid="ref12">12</xref>
        ]. The fragmentation of complex learning tasks without a knowledge of the boundaries between the
modules has a high degree of unsuccess. It is because it does not adhere to the real-work tasks: when a
learner knows how to deal a specific activity, from its acquired knowledge, but does not know the
interactions with the other parts, could have significative problems in applying it in the real field. This
ambivalence represents the so called “Transfer paradox” [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ].
      </p>
      <p>
        The Instructional design (ID) theory supports the course designers in this process and a specific
approach is called four-component Instructional Design (4C-ID) [
        <xref ref-type="bibr" rid="ref13">13</xref>
        ].
      </p>
      <p>In the digital companies, the instructional design of courses and their digitalization from the
traditional ones, is an open and daily challenge. The improvement under the technological side and the
contextual events accelerated the process of the rethinking of the courses. These course providers need
of rooted and well-structured methodologies, with schematic blueprint for a real use in practical
contexts.</p>
    </sec>
    <sec id="sec-2">
      <title>2. Instructional design and four component Instructional Design (4C-ID)</title>
      <p>
        The 4C-ID model, was developed by Jeroen J. G. van Merriënboer, in partnership with Paul
Kirschner [
        <xref ref-type="bibr" rid="ref11">11,</xref>
        ] is intensively used for the development of learning and training programs aimed at
acquiring complex cognitive skills, starting from the fundamental stage of the Complex learning. [14].
      </p>
      <p>This model is a tool for course and instructional design in a modular sense. These learning resources
are developed in order to boost the implementation of problem-solving strategies and their
understanding and automation. The model proposes four main components for each learning task:
• Learning task;
• Supportive information;
• Procedural information;
• Part-task practice.</p>
      <p>Each of these four pillars represents a specific moment for the design of any specific learning activity
and are crucial for the development of learning task inventory. Below a brief description of each
component.</p>
      <p>Learning task: these are the learning activities that proposes practical and laboratorial learning
experiences. These are conceived on real problem related to the field of learning/teaching where for the
achievement of the solution are needed skills, competences, and attitudes. This starts from the holistic
approach for the complex learning. The aim is to propose activities for an experiential learning in order
to transfer in a real environment the competences learnt. The single learning tasks has a high variability
and different structures that implies different solutions. The instructional designer should define
learning task with a progressive increase of difficulty.</p>
      <p>Supportive information: represents the learning resources showed during a learning task or
immediately before in order to create the right context. These includes data that could be important for
the student aimed at the management of the problem solving, elaboration and reasoning. The students
need the supportive information for a progress into the learning tasks or for advanced solutions of these,
allowing the creation of connections between different learning tasks.</p>
      <p>Procedural information: are crucial for the execution of routine tasks. Using this information, the
students are able to handle recursive procedures and for an improvement of the skills. The procedural
information is important as an explanation tool for a specific problem. A specific aspect of this
information is their presence in the timeline, these should be shown just-in-time during a specific
learning task when needed.</p>
      <p>Part-task practice: these are a facultative asset. These represents activities that train part of specific
competences, covering different dimensions of complex skills. The Part-task practices could be
automatized and are needed for the execution of complex learning tasks. These are proposed when the
student knows a specific routine and could be internally o externally to a specific learning task. A typical
use is for the creation of recurrent skills inside the learning tasks.

      <p>The need of adopting and customizing a design model in a digital learning company concerns both
typically organizational issues about production and more typically training issues. Under the
organizational point of view, the need to adopt an innovative and agile model concerns:
• allowing a homogeneous course design of the courses, beyond the differences and background
of the different instructional designers,</p>
      <p>• giving a reference design tool for course updates and evolutions, but also for any customization
requested by the client,
• focusing on a unique reference system for micro-design training and assessment tools,
• capitalizing experience and codify a “learning task inventory” to reuse over time.</p>
      <p>Adopting an agile and flexible model also means encouraging an approach that shows all possible
training solutions, that can be creatively selected, without losing the coherence of the intervention. From
the purely training point of view, the advantages of this method concern new and interesting
opportunities to:</p>
      <p>• mapping training and evaluation decisions and building complex and articulated interventions
for different difficulty, guidance and support levels,</p>
      <p>• encouraging an approach of concrete demonstration of competence and focus on expected
behaviour rather than on formal objectives,
• having an open but experience-oriented intervention system,
• referring to a learning map to be used to organize all project phases (from the content
production, evaluation system, tutoring system, delivery rules in LMS),</p>
      <p>• adopting, in addition to summative assessment models, continuous monitoring tools as
progressive assessment.</p>
      <p>From the organizational and training needs, basic model requirements were identified in:
• methodological accuracy and integrity,
• manageability and adequate design effort,
• adaptability to different contents,
• adaptability to different training methods.</p>

      <title>2.1.2. Learning Activities Inventory</title>
      <p>
        When an instructional designer creates a learning activities inventory has to cover four main aspects
listed below: [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]
      </p>
      <p>• Variability; for a correct transfer of the learning and in order to prevent that the competences
are learnt but with a great difficulty of application in real field, it is essential that the learning tasks
differ among them. This variability should be under different aspects, as the type of exercise, the
dimension of the learning tasks, etc.. The final goal for the student is to extract more general information
from the active learning and from different tasks</p>
      <p>• Task classes: this is another important aspect of the instructional design. The student could find
huge hurdles if the learning tasks are immediately difficult. The tasks should have a gradual increase,
starting from the simpler learning tasks to the activities that involve a more complex analysis and
acquisition of knowledge. The task classes should be conceived in line with the flow, typical in
gamification [16, 17]. The tasks should be designed balancing the knowledge of the learner with the
difficulty of the tasks, when the learner is in the initial stages, its competence and skills are low and the
learning tasks that it could handle needs to have a congruent level, at the same time when the
competences improve, the tasks should not be too easy, maintaining an engagement for the student. The
learning categories for each activity are called task class. Each task class have exercises at the same
level.</p>
      <p>• Support and guidance: the support is product-oriented, because the focus is on the learning
outcomes, while the guidance is process-oriented, and the main aspect to be covered is on the learning
processes of the student. The support and guidance should be not homogeneous across the course. Their
impact would decrease when the student is more confident and has learnt more elements. In each
activity the support and guidance should have a slope, with a continuous decrease.</p>
      <p>• Supportive versus procedural information: the first one is important for the non-recurrent tasks
and explain how is organized a learning domain and how deal with it. The supportive information is the
base to facilitate the development of new mental schemes that are useful for potential crosslink between
arguments and previous cognitive schemes. All these information is transversal for all the learning
activities. On the contrary, the procedural information is relevant for the recurrent tasks, that are
reproduced as routines.</p>

      <title>2.2. ID model operazionalization</title>
      <p>During the research, a first version of the design model was created. In the tools all theoretical ideas
and didactic choices are collected and condensed into a single design matrix. For the creation of this
file the authors used the ten steps 4C/ID model described above. In this section we show the different
parts of the files without the order of development (all the steps of the methodology were followed in
the current order).</p>
      <p>The authors created it as a Microsoft Excel worksheet, this first version is intended to provide an
agile tool in the experimental stage. After an adequate use and the collection of improvement inputs, a
new software version will be realized to give instructional designers a more advanced tool.</p>
      <p>The Microsoft Excel file consists of several parts, of which the central part is a "design matrix". The
file consists of several spreadsheets, divided into:
• “operative spreadsheets" in which the instructional designer can operate,
• "support spreadsheets" that collect all the design model information used in the "design matrix".</p>

        <title>Utility for the action verbs that can be used to write learning outcomes in the design matrix.</title>
        <p>The design matrix sheet called "Job, skills, design" is explained through its different parts
corresponding to the design phases.</p>
        <p>The name of this section highlights the purpose of the tool. It links the instructional design with
professional role and target skills by a strong reference to experiential learning.</p>
        <p>Starting from the professional role analysis (job description and skills mapping), the first activity is
to define the learning outcomes based as training objectives.</p>
        <p>First, we must describe work activities of the target job profile, both at macro and micro level (it
means analytically describe activities to be carried out). After this, the micro-activity is linked to
"observable competent behaviour" in a unique way to and it represents the learning outcome and
objective of training. The learning outcome / objective is defined by the concepts of: action, standard,
conditions, tools&amp;object.</p>
        <p>At this stage the distinction between recurring and non-recurring activities is relevant, which will be
fundamental in the definition of training activities.</p>
        <p>It should be noted that a job of the role can be divided into several micro-activities, some of which
can be of a recurrent type and therefore represent preliminary activities or entry requirements to the
course.</p>
        <p>Recurrent activities, developed in the step 10 for the design of the Part-tasks practices, are the routine
activities that are part of the work (e.g. in the activity of "monitoring new tenders and contracts", the
routine component of the activity is the part of "access to the monitoring platform, display of new
reports and consultation of information". While the non-recurring activity is "the analysis of the single
tender matching the requested characteristics ".</p>
        <p>The second section deals with the possibility of coordinating the definition of learning outcomes
with a set of taxonomies and skills frameworks. For now, 6 different taxonomies have been integrated
in the model:
• Bloom Taxonomy of teaching objectives
• ECF: ICT skills (e-CF 3.0 CWA Part 3)
• CEFR: language skills
• Key competences for lifelong learning
• Entrecomp: entrepreneurial skills
• Digcomp for digital skills.</p>
        <p>• All these frameworks are valued and filled out according to the aims and requests of the course
in design.</p>
        <p>Third part of the design matrix regards the definition of each “Learning task and Performance
assessment”. This is the central part of the 4C/ID model adopted, developed with the first three steps
(Design the learning tasks), because it allows to combine in a single learning outcome both the
experiential learning activity and its evaluation tool. The unification of these two activities has some
fundamental advantages.</p>
        <p>First of all, it allows to identify learning activities that are strongly connected to the job, such as
exercises, simulations, and experiments, in which experience is put into play as is the learning main
vector. On the other side, it allows to base the evaluation system design directly on the practical activity,
rather than on the dimension of knowledge. And that moves evaluation from focusing on conformity
(in accordance with course design system, alias “assessment on contents”) to focusing on the real
objective, as job behaviours’ improvement (expected performance).</p>
        <p>In addition to the ordinary summative assessment, this method also enriches the evaluation results,
by providing the adoption of:
• progressive assessment models,
• self-evaluation protocols.</p>
        <p>In practice it’s necessary to proceed first to the choice of the learning task, and therefore to move on
to the performance assessment and the related evaluation tool.</p>
        <p>After this, all information about learning task is to be defined. Starting from the learning task
declination as experiential and inductive activity, it is classified by the type of learning task:
• Self-evaluation,
• Exercise &amp; practice
• Explanation
• Self-study
• Materials</p>
        <p>And then the specific learning activity is selected. The tool uses the support sheet "Learning Task
Inventory" to propose a set of possible delivery activities to be chosen and micro-designed.</p>
        <p>The selected learning tasks must match variability and increasing level of complexity criteria. In the
case of activities at the same level of complexity, variability between learning tasks must be guaranteed.</p>
        <p>Identifying a learning task, the CLASS TASK level, based on one of the four aspect for the creation
of learning task inventory, must be defined in terms of the level of Support &amp; Guidance (high, medium,
low, none). It must progressively decrease according to the increase in user skills. The user
progressively becomes competent and autonomous during the course. In the spreadsheet it is possible
to link a learning activity to a previous and propaedeutic one.</p>
        <p>For learning activity classification (managed with the step 2 of 4C/ID) the tool automatically
incorporates all the information in terms of effort and costs estimate of each activity.</p>
        <p>In fact, the sheet “learning task inventory”, every activity is classified with information about:
• participants (for all, single, small group, class group)
• in presence and/or digital
• type of delivery and digital content support (in house/outside, videoconference, AR, VR,
bulletin boards, collaboration tools, presentations, editing tools, ... etc.)
• teacher / subject expert availability
• design and delivery effort estimate for classroom activities
• design and delivery effort estimate for digital activities
• estimated costs for classroom activities
• estimated costs for digital activities</p>
        <p>Last step is the definition of Procedural information (typically those given in digital tools and
platforms), designed in the step 7. These are all the information that support students in the routine
activities related to the learning task and concern:
• Procedural information: those are essentially help information and/or synthetic instructions (step
7)
• Cognitive rules: those are information about how to practically manage the give exercise (step
8)
• Constituent knowledge: those are the fundamental knowledge at stake in the performance of the
test (step 9)</p>
        <p>The final step is the definition of the Part Task Practice (step 10 of the design) for the activities
defined as recurrent. In this case the sub-activities to be trained and/ or guaranteed to enable the student
in the execution of the task are indicated. As well as the technical abilities, soft skills can also be
indicated.</p>
        <p>Then it is necessary to explain problem solving activity requested by the learning activity under 4
different conditions:
• Supportive information: information about how to manage the activity (examples, process
diagrams, theoretical model, useful information, etc.),
• Support &amp; Guidance: feedback indications, with contextualized suggestions for resolving the
activity,
• Cognitive strategy: rules and problem solving process implied in the exercise,
• Mental model: (knowledge map): structure of information related to the problem.</p>
        <p>For schematizing the components of the 4C/ID model and the elements of the design matrix, we
refer to the pyramid of Miller [18] for evaluation: (1) Knows, (2) Know How, (3) Show How, (4) Does.
It is clear from this schematization that experiential learning tasks are positioned at the top of the
pyramid. At levels 3 and 4 there are more experiential activities and objectives.</p>
        <p>Procedural information (in recurrent components) and part-task practice, concern useful knowledge
for the activity execution.</p>
        <p>Supportive information concern about information and cognitive strategies related to problem
solving that are the basis of the execution of the learning task.</p>
        <p>There is a substantial evolution of digital learning from a content-oriented approach to an
experience-oriented approach. This means strongly moving the instructional design from the
verification of the teachings to the evaluation of real tasks execution in a perspective of people readiness
to job challenges. An experiential approach not only adapts to adult education, but especially in digital
contexts.</p>

      <title>3. Conclusions and next steps</title>
      <p>The experimentation of the 4C/ID model was immediately interesting for the important focus on
experientiality and evaluation models that allow the company instructional designers to focus on target
behaviors rather than on content.</p>
      <p>This opportunity represents an important vector for transforming learning programs in a new
blended/hybrid perspective by strongly focusing on methods rather than on tools functions and power.
Today, for a digital learning company, it becomes increasingly important to propose complex training
programs without constraints of technological chances or barriers due to users’ level of digitalization.
It is also strategic enhancing the experiential learning methods to rapidly increase the learning impact
on operative results in companies.</p>
      <p>The paper proposes a practical guide for instructional designer, with a tool created on the 4C/ID
model. The tool aims to be a simple and useful device for learning provider, in the definition of a course
considering contextual aspects of the design, including budgeting, management of resources and
incidental issues, starting from the Complex Learning methodology.</p>
      <p>For those reasons, the research next steps will concern:
• the practical experimentation of the design model on specific needs in a real client context,
evaluating its implementation and the outcomes regarding the learning objectives,</p>
      <p>• the theoretical study on how effectively analysing learning impact on professional and
organizational goals.</p>
