ERP implementation methodologies and frameworks: a literature review

Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

Practical work in science education: a systematic literature review

Practical work has taken a leading role in science teaching, particularly since the 1960s. Its goals are mainly oriented toward the development of sensitivity and taste for the study of physical and natural phenomena, bringing students closer to the daily reality experienced by researchers working in these areas of knowledge, while promoting educational success. However, these purposes have not always been achieved so, over time, limitations to the way that practical work has been developed have also been identified. In order to recognize the current state of the art on the development of the practical work in the teaching of sciences, a systematic literature review was designed, especially focused on the definition of the concept of practical work, its advantages, evaluation methodologies, and the criticism/limitations attributed to its implementation. To this end, four databases and one aggregator were used, to identify 53 international scientific publications. Analysis of this corpus allowed the identification of 8 categories associated to the concept of practical work, 5 categories associated to its advantages, 6 categories with the types/methodologies of evaluation and 5 categories associated with the limitations of this methodology. (From this analysis) it is concluded that most authors considers that the main idea integrative idea of the concept of practical work should be the manipulation of materials in practical activities (hands-on style), and the main advantage of this methodology comes from the fusion between the development of practical skills and the conceptual understanding (minds-on). In the evaluation methods, the context, procedures and specific instruments are favored and the main limitation pointed to this methodology is that the way practical work is implemented, is often not in agreement with the methods and techniques used by scientists and researchers

The Effects of the COVID-19 Pandemic on the Digital Competence of Educators

The Covid-19 pandemic is having an undeniable impact on all the statements of society. Regarding teaching and learning activities, most educational institutions suspended in-person instruction and moved to remote learning during the lockdown of March and April 2020. Although nowadays many countries have progressively re-opened their educational systems, blended learning is a common practice aimed to reduce the spread of the Covid-19 disease. This disruption has supposed an unprecedented acceleration to the digitalization of teaching and learning. Teaching professionals have been forced to develop their digital competence in a short amount of time, getting mastery in the management of information, the creation of audiovisual contents, and the use of technology to keep their students connected. This Special Issue presents contributions regarding the adoption of distance learning strategies, experiences, or lessons learned in this domain

Defining and Assessing Critical Thinking: toward an automatic analysis of HiEd students’ written texts

L'obiettivo principale di questa tesi di dottorato è testare, attraverso due studi empirici, l'affidabilità di un metodo volto a valutare automaticamente le manifestazioni del Pensiero Critico (CT) nei testi scritti da studenti universitari. Gli studi empirici si sono basati su una review critica della letteratura volta a proporre una nuova classificazione per sistematizzare le diverse definizioni di CT e i relativi approcci teorici. La review esamina anche la relazione tra le diverse definizioni di CT e i relativi metodi di valutazione. Dai risultati emerge la necessità di concentrarsi su misure aperte per la valutazione del CT e di sviluppare strumenti automatici basati su tecniche di elaborazione del linguaggio naturale (NLP) per superare i limiti attuali delle misure aperte, come l’attendibilità e i costi di scoring. Sulla base di una rubrica sviluppata e implementata dal gruppo di ricerca del Centro di Didattica Museale – Università di Roma Tre (CDM) per la valutazione e l'analisi dei livelli di CT all'interno di risposte aperte (Poce, 2017), è stato progettato un prototipo per la misurazione automatica di alcuni indicatori di CT. Il primo studio empirico condotto su un gruppo di 66 docenti universitari mostra livelli di affidabilità soddisfacenti della rubrica di valutazione, mentre la valutazione effettuata dal prototipo non era sufficientemente attendibile. I risultati di questa sperimentazione sono stati utilizzati per capire come e in quali condizioni il modello funziona meglio. La seconda indagine empirica era volta a capire quali indicatori del linguaggio naturale sono maggiormente associati a sei sottodimensioni del CT, valutate da esperti in saggi scritti in lingua italiana. Lo studio ha utilizzato un corpus di 103 saggi pre-post di studenti universitari di laurea magistrale che hanno frequentato il corso di "Pedagogia sperimentale e valutazione scolastica". All'interno del corso, sono state proposte due attività per stimolare il CT degli studenti: la valutazione delle risorse educative aperte (OER) (obbligatoria e online) e la progettazione delle OER (facoltativa e in modalità blended). I saggi sono stati valutati sia da valutatori esperti, considerando sei sotto-dimensioni del CT, sia da un algoritmo che misura automaticamente diversi tipi di indicatori del linguaggio naturale. Abbiamo riscontrato un'affidabilità interna positiva e un accordo tra valutatori medio-alto. I livelli di CT degli studenti sono migliorati in modo significativo nel post-test. Tre indicatori del linguaggio naturale sono 5 correlati in modo significativo con il punteggio totale di CT: la lunghezza del corpus, la complessità della sintassi e la funzione di peso tf-idf (term frequency–inverse document frequency). I risultati raccolti durante questo dottorato hanno implicazioni sia teoriche che pratiche per la ricerca e la valutazione del CT. Da un punto di vista teorico, questa tesi mostra sovrapposizioni inesplorate tra diverse tradizioni, prospettive e metodi di studio del CT. Questi punti di contatto potrebbero costituire la base per un approccio interdisciplinare e la costruzione di una comprensione condivisa di CT. I metodi di valutazione automatica possono supportare l’uso di misure aperte per la valutazione del CT, specialmente nell'insegnamento online. Possono infatti facilitare i docenti e i ricercatori nell'affrontare la crescente presenza di dati linguistici prodotti all'interno di piattaforme educative (es. Learning Management Systems). A tal fine, è fondamentale sviluppare metodi automatici per la valutazione di grandi quantità di dati che sarebbe impossibile analizzare manualmente, fornendo agli insegnanti e ai valutatori un supporto per il monitoraggio e la valutazione delle competenze dimostrate online dagli studenti.The main goal of this PhD thesis is to test, through two empirical studies, the reliability of a method aimed at automatically assessing Critical Thinking (CT) manifestations in Higher Education students’ written texts. The empirical studies were based on a critical review aimed at proposing a new classification for systematising different CT definitions and their related theoretical approaches. The review also investigates the relationship between the different adopted CT definitions and CT assessment methods. The review highlights the need to focus on open-ended measures for CT assessment and to develop automatic tools based on Natural Language Processing (NLP) technique to overcome current limitations of open-ended measures, such as reliability and costs. Based on a rubric developed and implemented by the Center for Museum Studies – Roma Tre University (CDM) research group for the evaluation and analysis of CT levels within open-ended answers (Poce, 2017), a NLP prototype for the automatic measurement of CT indicators was designed. The first empirical study was carried out on a group of 66 university teachers. The study showed satisfactory reliability levels of the CT evaluation rubric, while the evaluation carried out by the prototype was not yet sufficiently reliable. The results were used to understand how and under what conditions the model works better. The second empirical investigation was aimed at understanding which NLP features are more associated with six CT sub-dimensions as assessed by human raters in essays written in the Italian language. The study used a corpus of 103 students’ pre-post essays who attended a Master's Degree module in “Experimental Education and School Assessment” to assess students' CT levels. Within the module, we proposed two activities to stimulate students' CT: Open Educational Resources (OERs) assessment (mandatory and online) and OERs design (optional and blended). The essays were assessed both by expert evaluators, considering six CT sub-dimensions, and by an algorithm that automatically calculates different kinds of NLP features. The study shows a positive internal reliability and a medium to high inter-coder agreement in expert evaluation. Students' CT levels improved significantly in the post-test. Three NLP indicators significantly correlate with CT total score: the Corpus Length, the Syntax Complexity, and an adapted measure of Term Frequency- Inverse Document Frequency. The results collected during this PhD have both theoretical and practical implications for CT research and assessment. From a theoretical perspective, this thesis shows unexplored similarities among different CT traditions, perspectives, and study methods. These similarities could be exploited to open up an interdisciplinary dialogue among experts and build up a shared understanding of CT. Automatic assessment methods can enhance the use of open-ended measures for CT assessment, especially in online teaching. Indeed, they can support teachers and researchers to deal with the growing presence of linguistic data produced within educational 4 platforms. To this end, it is pivotal to develop automatic methods for the evaluation of large amounts of data which would be impossible to analyse manually, providing teachers an

Business process modelling in ERP implementation literature review

Business processes are the backbone of any Enterprise Resource Planning (ERP) implementation. Business process modelling (BPM) has become essential for modern, process driven enterprises due to the vibrant business environments. As a consequence enterprises are dealing with a substantial rate of organizational and business processes change. Business process modelling enables a common understanding and analysis of the business processes, which is the first step in every ERP implementation methodology (blueprint phase). In order to represent enterprise processes models in an accurate manner, it is paramount to choose a right business process modeling technique and tool. The problem of many ERP projects rated as unsuccessful is directly connected to a lack of use of business process models and notations during the blueprint phase. Also, blueprint implementation phase is crucial in order to fit planned processes in an organization with processes implemented in the solution. However, business analysts and ERP implementation professionals have substantial difficulties to navigate through a large number of theoretical models and representational notations that have been proposed for business process modeling (BPM). As the availability of different business process modeling references is huge, it is time consuming to make review and classification of all modeling techniques. Therefor, in reality majority of ERP implementations blueprint documents have no business process modeling included in generating blueprint documents. Choosing the right model comprise the purpose of the analysis and acquaintance of the available process modelling techniques and tools. The number of references on business modelling is quit large, so it is very hard to make a decision which modeling notation or technique to use. The main purpose of this paper is to make a review of business process modelling literature and describe the key process modelling techniques. The focus will be on all business process modeling that could be used in ERP implementations, specifically during the blueprint phase of the implementation process. Detailed review of BPM (Business process modeling) theoretical models and representational notations, should assist decision makers and ERP integrators in comparatively evaluating and selecting suitable modeling approaches
