- Abstract
The main aim of this paper is to assess the level of knowledge, attitude and practice of university teachers regarding plagiarism in Bangladesh. An online questionnaire consisted of 20 knowledge questions, 23 attitude items, and 18 practice questions was created using Google Forms. The link to the questionnaire was sent via email to university teachers. The total correct answers for knowledge and practice questions, and the total attitude score were converted to percentile scores and categorized accordingly as poor (< mean -- 1 SD), average (mean ± 1 SD), and good (> mean + 1 SD). Bivariate analyses were conducted to compare the total knowledge, attitude and practice scores based on demographic and academic variables. Multiple linear regressions were used to identify the association between knowledge, attitude and practice scores, and other covariates. The findings revealed an average level of knowledge, attitude and practice regarding plagiarism among the majority of university teachers. The knowledge, attitude and practice scores were significantly higher for teachers who attended academic writing workshops compared to those who did not attend such events. Demographic and academic variables did not impact knowledge and attitude scores. However, the number of papers published in the last two years and their indexing in Web of Science (WoS) or Scopus significantly impacted attitude and knowledge scores. The multiple regression analyses showed that the practice score was significantly associated with age, highest education, and knowledge.

National Association of School Nurses, Ondeck, Lynnette, Combe, Laurie, and Feeser, Cindy Jo
- Abstract
It is the position of the National Association of School Nurses (NASN) that prevention, early recognition, intervention and treatment of child maltreatment are critical to the physical well-being and academic success of students. Registered professional school nurses (hereinafter referred to as school nurses) serve a vital role in the recognition of early signs of child maltreatment, assessment, identification, intervention, reporting, referral and follow-up of children in need. School nurses are uniquely qualified to participate as members of interdisciplinary teams to collaborate with school personnel, community healthcare professionals, students and families.

- Abstract
Peer assessment adds value when students provide "helpful" feedback to their peers. But, this begs the question of how we determine "helpfulness." One important aspect is whether the review detects problems in the submitted work. To recognize problem detection, researchers have employed NLP and machine-learning text classification methods. Past studies have used datasets that were narrowly focused on a small number of classes in specific academic fields. This paper reports on how well models trained on one dataset or field perform on data from classes that are unlike the classes whose data they have been trained on. Specifically we took a model developed with data from a computer science class with several programming assignments, and tried to transfer it onto an education class focused more on writing research papers. We have attempted to perform such a task on a few models including logistic regression classifier, random forest classifier, multinomial naive bayes classifier and support vector machine. We made several attempts to raise the accuracy of classification, including lemmatizing to deduct variation in data input, and active learning strategies. [For the full proceedings, see ED607784.]

- Abstract
Imagine a student using an intelligent tutoring system. A researcher records the correctness and time of each of your attempts at solving a math problem, nothing more. With no names, no birth dates, no connections to the school, you would think it impossible to track the answers back to the class. Yet, class sections have been identified with no more data than this. This paper recounts shocking episodes where educational data was used to re-identify individual students, build profiles on students, and commit fraud. We look at the ethical principles that underlie privacy as it relates to research data, and discuss ethical issues in data mining relating to social networks and big data. We explore four major types of data used in EDM [educational data mining]: (i) clickstream data, (ii) student-interaction data, (iii) evaluative data, and (iv) demographic data. Each type of data can be harmful if disclosed in particular contexts, even if all personally identifiable information is removed. We consider laws and legal precedents controlling access to student data in the United States and the European Union. This paper concludes by describing some practical situations in EDM and suggesting privacy policies that satisfy the ethical concerns raised earlier in the paper.

- Abstract
The dropout of students is one of the major obstacles that ruin the improvement of higher education quality. To facilitate the study of students' dropout in Moroccan universities, this paper aims to establish a clustering approach model based on machine learning algorithms to determine Moroccan universities categories. Our objective in this article is to present a theoretical model capable of identifying higher education institutions that are similar in the dropout phenomenon. To avoid making Educational Data Mining Analysis on each higher educational programs predict students' performance, with such a classification we can reduce the number of studies to be done on one institution in each category of universities.

The paper reports the results of a comparative assessment concerned with the effectiveness of identifying the basic forms of partial discharges (PD) measured by the acoustic emission technique (AE), carried out by application of selected machine learning methods. As part of the re-search, the identification involved AE signals registered in laboratory conditions for eight basic classes of PDs that occur in paper-oil insulation systems of high-voltage power equipment. On the basis of acoustic signals emitted by PDs and by application of the frequency descriptor that took the form of a signal power density spectrum (PSD), the assessment involved the possibility of identifying individual types of PD by the analyzed classification algorithms. As part of the research, the results obtained with the use of five independent classification mechanisms were analyzed, namely: k-Nearest Neighbors method (kNN), Naive Bayes Classification, Support Vector Machine (SVM), Random Forests and Probabilistic Neural Network (PNN). The best results were achieved using the SVM classification tuned with polynomial core, which obtained 100% accuracy. Similar results were achieved with the kNN classifier. Random Forests and Naïve Bayes obtained high accuracy over 97%. Throughout the study, identification algorithms with the highest effectiveness in identifying specific forms of PD were established.

- Abstract
Despite the unquestionable academic interest on corpus-based approaches to language education, the use of corpora by teachers in their everyday practice is still not very widespread. One way to promote usage of corpora in language teaching is by making pedagogically appropriate corpora, labelled with different types of problems (for instance, sensitive content, offensive language, structural problems), so that teachers can select authentic examples according to their needs. Because manually labelling corpora is extremely time-consuming, we propose to use crowdsourcing for this task. After a first exploratory phase, we are currently developing a multimode, multilanguage game in which players first identify problematic sentences and then classify them.

College Board and Kim, YoungKoung Rachel
- Abstract
Presented at the national conference for AERA (American Educational Research Association) in April 2009. The large variability of SAT taker population across states makes state-by-state comparisons of the SAT scores challenging. Using a mixture modeling approach, therefore, the current study presents a method of identifying subpopulations in terms of SAT scores while taking into account the percentage of SAT takers so that state SAT scores within a subpopulation can be properly compared.

- Abstract
The purpose of this paper is to study identification and estimation of causal effects in experiments with multiple sources of noncompliance. This research design arises in many applications in education when access to oversubscribed programs is partially determined by randomization. Eligible households decide whether or not to comply with the intended treatment. The paper treats program participation as the outcome of a decision process with five latent household types. We show that the parameters of the underlying model of program participation are identified. Our proofs of identification are constructive and can be used to design a GMM estimator for all parameters of interest. We apply our new methods to study the effectiveness of magnet programs in a large urban school district. Our findings show that magnet programs help the district to attract and retain students from households that are at risk of leaving the district. These households have higher incomes, are more educated, and have children that score higher on standardized tests than households that stay in district regardless of the outcome of the lottery.

Melton, Britany, Marchese, Nancy, and Weiss, Mary Jane
- Abstract
The provision of applied behavior analytic (ABA) services is a highly efficacious intervention approach most often used to improve the lives of individuals with autism spectrum disorder (ASD)/Autistics. Given the advancement of the field, more nuanced skill sets of behavior analysts, such as compassionate care skills, are emerging as the focus of intervention as measurable, observable, and essential. As the field progresses, the identification, refinement, and assessment of more nuanced skills become crucial to the success of our interventions. Leading with a compassionate approach that balances habilitation with client happiness, assent, and engagement is of the utmost importance. This paper discusses the current trend in existing compassionate care literature and how those evaluations may potentially be extended to direct interventionists and Registered Behavior Technicians. In this paper, we argue that a behavioral framework should be used to conceptualize, train, and evaluate the demonstration of these skills in front line ABA practitioners.

Tsabari, Stav, Segal, Avi, and Gal, Kobi
- Abstract
Automatically identifying struggling students learning to program can assist teachers in providing timely and focused help. This work presents a new deep-learning language model for predicting "bug-fix-time", the expected duration between when a software bug occurs and the time it will be fixed by the student. Such information can guide teachers' attention to students most in need. The input to the model includes snapshots of the student's evolving software code and additional meta-features. The model combines a transformerbased neural architecture for embedding students' code in programming language space with a time-aware LSTM for representing the evolving code snapshots. We evaluate our approach with data obtained from two Java development environments created for beginner programmers. We focused on common programming errors which differ in their difficulty and whether they can be uniquely identified during compilation. Our deep language model was able to outperform several baseline models that use an alternative embedding method or do not consider how the programmer's code changes over time. Our results demonstrate the added value of utilizing multiple code snapshots to predict bug-fix-time using deep language models for programming. [For the complete proceedings, see ED630829.]

Lynnette Brice, Alison Harrison, and Alan Cadwallader
- Abstract
The purpose of this paper is to share insights gained from the discovery, design, and delivery phases of creating a three-tiered model of non-academic learning support in open, distance, and flexible learning (ODFL): "Learner Engagement and Success Services (LESS)", at Open Polytechnic | Te Pukenga, New Zealand. Presented as a case study, this paper discusses the early vision of the model, examines current understanding relating to learner support and engagement, and describes the successes and challenges faced in bringing this vision to reality. It outlines challenges relating to the emergent use of learning analytics (LA) in identifying "exception" learners, the contestability of ethical use and choices of data, and the rapid evolution and devolution of commercially available communication tools. The tiered model is described as a scalable blend of human and technology-enabled interventions and services, underpinned by the values of agency and equity. The components of this model could be replicated, and its success is measurable.

- Abstract
In today's data-sharing paradigm, personal data has become a valuable resource that intensifies the risk of unauthorized access and data breach. Increased data mining techniques used to analyze big data have posed significant risks to data security and privacy. Consequently, data breaches are a significant threat to individual privacy. Privacy is a multifaceted concept covering many areas, including the right to access, erasure, and rectify personal data. This paper explores the legal aspects of privacy harm and how they transform into legal action. Privacy harm is the negative impact to an individual as a result of the unauthorized release, gathering, distillation, or expropriation of personal information. Privacy Enhancing Technologies (PETs) emerged as a solution to address data privacy issues and minimize the risk of privacy harm. It is essential to implement privacy enhancement mechanisms to protect Personally Identifiable Information (PII) from unlawful use or access. FIPPs (Fair Information Practice Principles), based on the 1973 Code of Fair Information Practice (CFIP), and the Organization for Economic Cooperation and Development (OECD), are a collection of widely accepted, influential US codes that agencies use when evaluating information systems, processes, programs, and activities affecting individual privacy. Regulatory compliance places a responsibility on organizations to follow best practices to ensure the protection of individual data privacy rights. This paper will focus on FIPPs, relevance to US state privacy laws, their influence on OECD, and reference to the EU General Data Processing Regulation. (GDPR).

127. AI, Biometric Analysis, and Emerging Cheating Detection Systems: The Engineering of Academic Integrity?
- Author

Oravec, Jo Ann
- Abstract
Cheating behaviors have been construed as a continuing and somewhat vexing issue for academic institutions as they increasingly conduct educational processes online and impose metrics on instructional evaluation. Research, development, and implementation initiatives on cheating detection have gained new dimensions in the advent of artificial intelligence (AI) applications; they have also engendered special challenges in terms of their social, ethical, and cultural implications. An assortment of commercial cheating-detection systems have been injected into educational contexts with little input on the part of relevant stakeholders. This paper expands several specific cases of how systems for the detection of cheating have recently been implemented in higher education institutions in the US and UK. It investigates how such vehicles as wearable technologies, eye scanning, and keystroke capturing are being used to collect the data used for anti-cheating initiatives, often involving systems that have not gone through rigorous testing and evaluation for their validity and potential educational impacts. The paper discusses accountability- and policy-related issues concerning the outsourcing of cheating detection in institutional settings in the light of these emerging technological practices as well as student resistance against the systems involved. The cheating-detection practices can place students in a disempowered, asymmetrical position that is often at substantial variance with their cultural backgrounds.

128. Breaking down Bias: A Practical Framework for the Systematic Evaluation of Source Bias
- Author

Burkholder, Joel M. and Phillips, Kat
- Abstract
What is bias? A review of the library literature reveals no attempts to define the concept. Nor does it reveal systematic attempts to develop interventions that teach the identification and evaluation of bias. Current pedagogical approaches (checklists and bias charts) tend to assume a self-evident definition that categorises bias as unquestioningly bad and disqualifying. Current approaches, however, fail to recognise the cognitive complexity of decoding bias within a source. A decoding process includes identifying the type of bias, determining an objective baseline, recognising biased features, and analysing bias's impact. Based on work done from several fields--argumentation theory, media bias, media literacy, and history education--this paper proposes an operational definition of bias and a practical framework for conceptualising a process to identify and evaluate bias. This paper will explore the limitations of this framework, as well as existing source evaluation paradigms. If librarians want to prepare individuals to participate in a post-truth society, where disinformation weaponises bias by appealing to emotions and beliefs rather than facts, an inclusive and nuanced conception of bias is a necessary component of library instruction.

National Bureau of Economic Research, Imberman, Scott A., and Kugler, Adriana D.
- Abstract
In response to low take-up, many public schools have experimented with moving breakfast from the cafeteria to the classroom. We examine whether such a program increases performance as measured by standardized test scores, grades and attendance rates. We exploit quasi-random timing of program implementation that allows for a difference-in-differences identification strategy. Our main identification assumption is that schools where the program was introduced earlier would have evolved similarly to those where the program was introduced later. We find that in-class breakfast increases both math and reading achievement by about one-tenth of a standard deviation relative to providing breakfast in the cafeteria. Moreover, we find that these effects are most pronounced for low performing, free-lunch eligible, Hispanic, and low BMI students. We also find some improvements in attendance for high achieving students but no impact on grades.

- Abstract
Analysts often examine the black-white test score gap conditional on family income. Typically only a current income measure is available. We argue that the gap conditional on permanent income is of greater interest, and we describe a method for identifying this gap using an auxiliary data set to estimate the relationship between current and permanent income. Current income explains only about half as much of the black-white test score gap as does permanent income, and the remaining gap in math achievement among families with the same permanent income is only 0.2 to 0.3 standard deviations in two commonly used data sets. When we add permanent income to the controls used by Fryer and Levitt (2006), the unexplained gap in 3rd grade shrinks below 0.15 standard deviations, less than half of what is found with their controls.

Steven Moore, John Stamper, Norman Bier, and Mary Jean Blink
- Abstract
In this paper we show how we can utilize human-guided machine learning techniques coupled with a learning science practitioner interface (DataShop) to identify potential improvements to existing educational technology. Specifically, we provide an interface for the classification of underlying Knowledge Components (KCs) to better model student learning. The configurable interface allows users to quickly and accurately identify areas of improvement based on the analysis of learning curves. We present two cases where the interface and accompanying methods have been applied in the domains of geometry and psychology to improve upon existing student models. Both cases present outcomes of better models that more closely model student learning. We reflect on how to iterate upon the educational technology used for the respective courses based on these better models and further opportunities for utilizing the system to other domains, such as computing principles.

National Bureau of Economic Research and Fryer, Roland G.
- Abstract
After decades of narrowing, the achievement gap between black and white school children widened in the 1990s--a period when the labor market rewards for education were increasing. This presents an important puzzle for economists. In this chapter, I investigate the extent to which economic models of segregation, information-based discrimination, peer dynamics, and identity can explain this puzzle. Under a reasonable set of assumptions, models of peer dynamics and identity are consistent with the time-series data. Segregation and models of discrimination both contradict the trends in important ways.

- Abstract
While the rise in childhood obesity is clear, the policy ramifications are not. School nutrition programs such as the School Breakfast Program (SBP) have come under much scrutiny. However, the lack of experimental evidence, combined with non-random selection into these programs, makes identification of the causal effects of such programs difficult. In the case of the SBP, this difficulty is exacerbated by the apparent lack of exclusion restrictions. Here, we compare via Monte Carlo study several existing estimators that do not rely on exclusion restrictions for identification. In addition, we propose two new estimation strategies. Simulations illustrate the usefulness of our new estimators, as well as provide applied researchers several practical guidelines when analyzing the causal effects of binary treatments. More importantly, we find consistent evidence of a beneficial causal effect of SBP participation on childhood obesity when applying estimators designed to circumvent selection on unobservables.

National Bureau of Economic Research, Babcock, Philip, and Betts, Julian R.
- Abstract
Do smaller classes boost achievement mainly by helping teachers impart specific academic skills to students with low academic achievement? Or do they do so primarily by helping teachers engage poorly behaving students? The analysis uses the grade 3 to 4 transition in San Diego Unified School District as a source of exogenous variation in class size (given a California law funding small classes until grade 3). Grade 1 report cards allow separate identification of low-effort and low-achieving students. Results indicate that elicitation of effort or engagement, rather than the teaching of specific skills, may be the dominant channel by which small classes influence disadvantaged students.

Michaela Horniaková and Markéta Píšová
- Abstract
Vertebrate species knowledge is one of the predictors of pupils' understanding of biodiversity. This study will describe vertebrate species identification skills of pupils from the Czech Republic. Altogether, the research tool included 30 vertebrate species, out of which five were fish, three were amphibians, three were reptiles, nine were birds, and 10 were mammals. The research tool consisted of 22 pictures, three footprints, two silhouettes, and three sounds. In addition, we evaluated the influence of variable factors on vertebrate species knowledge, which the research tool also contained. The paper will describe the percentage success rate of vertebrate species knowledge of 1537 respondents. On average pupils could identify nearly 15 species. The results showed that differences in species knowledge were statistically significant mostly by pupils' expectations (self-efficacy) or their results and educational level. In general, younger students identified animals worse than students of higher levels of education. Moreover, significant differences were confirmed between the five classes of vertebrates. Mammals were the best-identified class, followed by amphibians and fish; reptiles and birds were the least correctly identified. While educational level played a significant role in identification skills, the results revealed that the pupils' hometown did not play a significant role.

Rodriguez, Jon-Marc G. and Jones, Steven R.
- Abstract
In this paper, we describe a framework for characterizing students' graphical reasoning, focusing on providing an empirically-based list of students' graphical resources. The graphical forms framework builds on the knowledge-in-pieces perspective of cognitive structure to describe the intuitive ideas, called "graphical forms", that are activated and used to interpret and construct graphs. In this study, we expand on the current knowledge base related to the specific graphical forms used by students. Based on data involving pairs of students interpreting and constructing graphs we present a list of empirically documented graphical forms and organize them according to similarity. We end with implications regarding graphical forms' utility in understanding how students construct graphical meanings and how instructors can support students in graphical reasoning.

- Abstract
Over the years, researchers have studied novice programming behaviors when doing assignments and projects to identify struggling students. Much of these efforts focused on using student programming and interaction features to predict student success at a course level. While these methods are effective at early detection of struggling students in the long run, there is also a need to identify struggling students during an assignment so that we can provide proactive intervention to prevent unproductive struggle and frustration. This work proposes a data-driven method that uses student trace logs to identify struggling moments during a programming assignment and determine the appropriate time for an intervention. We define a struggling moment as not achieving significant progress within a certain amount of time, relative to the amount of progress made and time taken in a sample student dataset. The paper describes how we determine significant progress and a time threshold for struggling students. We validated our algorithm's classification of struggling and progressing moments with experts rating whether they believe an intervention is needed for a sample of 20% of the dataset. The result shows that our automatic struggle detection method can accurately detect struggling students with less than 2 minutes of work with over 77% estimated accuracy. Our work contributes significantly to building proactive immediate support features for intelligent programming environments. [For the full proceedings, see ED615472.]

143. What You Apply Is Not What You Learn! Examining Students' Strategies in German Capitalization Tasks

- Abstract
The ability to spell correctly is a fundamental skill for participating in society and engaging in professional work. In the German language, the capitalization of nouns and proper names presents major difficulties for both native and nonnative learners, since the definition of what is a noun varies according to one's linguistic perspective. In this paper, we hypothesize that learners use different cognitive strategies to identify nouns. To this end, we examine capitalization exercises from more than 30,000 users of an online spelling training platform. The cognitive strategies identified are syntactic, semantic, pragmatic, and morphological approaches. The strategies used by learners overlap widely but differ by individual and evolve with grade level. The results show that even though the pragmatic strategy is not taught systematically in schools, it is the most widespread and most successful strategy used by learners. We therefore suggest that highly granular learning process data can not only provide insights into learners' capabilities and enable the creation of individualized learning content but also inform curriculum development.

147. Reading between the Lines: Three Essays on the Development and Implementation of Michigan's Read by Grade Three Law

Amy Cummings
- Abstract
Over the past two decades, U.S. states have widely adopted early literacy policies. These policies have shown short-term success in enhancing K-3 literacy skills. However, the reasons behind their widespread adoption and the factors driving their success are poorly understood. This three-paper dissertation focuses on Michigan's Read by Grade Three Law, enacted in 2016, to delve into the adoption and implementation of these policies. The Read by Grade Three Law is an informative case study because it is one of the U.S.'s most comprehensive early literacy policies. The first paper employs interviews and policy document analysis to explore the law's adoption and the dissemination of early literacy policies across states, highlighting the significant role of policy entrepreneurs. The second and third papers examine the policy's implementation, specifically its family engagement requirement and districts' methods to identify students with "reading deficiencies." The second paper analyzes data from the Michigan Department of Education and educator surveys spanning 2019-2023, uncovering that only 20% of eligible students receive "Read at Home" family engagement plans. The findings highlight considerable differences among districts and demonstrate how educators' understanding and perceptions are closely linked to the execution of these plans. The third paper uses superintendent survey data and state records from the 2021-22 school year to investigate how districts identify students with "reading deficiencies," making them eligible for supports such as "Read at Home" plans. The results reveal that districts use diverse measures to identify students. These variations are related to significant disparities in identification rates, with implications for which students receive literacy support under the Read by Grade Three Law. Together, these studies illuminate the complexities of policy adoption and implementation, enhancing our understanding of early literacy policies and laying the groundwork for future research on their mechanisms of success.

148. The Traumatic Aspect of Naming: Psychoanalysis and the Freirean Subject of (Class) Antagonism
- Author
-
Alex J. Armonda
- Abstract
Deploying a Lacanian conceptual framework, this article interrogates the psychoanalytic underpinnings of Paulo Freire's dialogical method of critical pedagogy. The paper advances the claim that the transformative efficacy of Freirean dialogue is rooted in its unique ability to confront and engage the repressed element of trauma, or what Lacan calls the "real." The author suggests that the locus of trauma stands as the elusive, yet central and constitutive axis around which Freire's dialogical engagement turns. Following psychoanalysis' attention to biography, the paper first examines how Freire's personal experience of exile informs his philosophical orientation to being, politics, and education. Turning to a specific classroom event Freire outlines in "Pedagogy of Hope," the paper then develops a new interpretation of Freire's idea of naming, and through Lacanian analysis, extends Freire's insight on the relationship between psyche, ideology, and social antagonism. Pushing the idea of class subjectivity in Freire beyond its familiar determinants (namely as an 'identity'), the paper resituates the notion of radical subjectivity in critical pedagogy as the effect of a traumatic loss or gap in the sociosymbolic order of being. The author argues that the 'naming event' in Freire is formally rooted in an encounter with this unconscious gap. To conclude, the paper offers critical educators some new points of departure for conceptualizing the transformative labor of problem-posing dialogue.

Hashem Alshurafat, Merwiey Alaqrabawi, and Mohannad Obeid Al Shbail
- Abstract
This paper aims to identify and explore the learning objectives outlining the core knowledge for forensic accounting education. Bloom's taxonomy is used to outline and analyze the core knowledge for forensic accounting education (e.g. fraud examination, litigation support, business valuation, and IT forensic accounting) in 15 Australian universities that provide forensic accounting courses. Furthermore, this paper applies a qualitative method to forensic accounting curricula, handbooks, and syllabi. These educational documents were retrieved from Australian universities. The findings report learning objectives under core content knowledge distributed over Bloom's cognitive areas. This study also provides a unified set of learning objectives to harmonize forensic accounting courses' teaching and learning processes. The most promising contribution of the paper is to provide a set of learning objectives in all forensic accounting subtopics. The main implications of this paper are relevant to forensic accounting educators, students, standard setters, researchers, regulators, and curricula designers.

Gloria Gagliardi
- Abstract
Background: In the past few years there has been a growing interest in the employment of verbal productions as digital biomarkers, namely objective, quantifiable behavioural data that can be collected and measured by means of digital devices, allowing for a low-cost pathology detection, classification and monitoring. Numerous research papers have been published on the automatic detection of subtle verbal alteration, starting from written texts, raw speech recordings and transcripts, and such linguistic analysis has been singled out as a cost-effective method for diagnosing dementia and other medical conditions common among elderly patients (e.g., cognitive dysfunctions associated with metabolic disorders, dysarthria). Aims: To provide a critical appraisal and synthesis of evidence concerning the application of natural language processing (NLP) techniques for clinical purposes in the geriatric population. In particular, we discuss the state of the art on studying language in healthy and pathological ageing, focusing on the latest research efforts to build non-intrusive language-based tools for the early identification of cognitive frailty due to dementia. We also discuss some challenges and open problems raised by this approach. Methods & Procedures: We performed a scoping review to examine emerging evidence about this novel domain. Potentially relevant studies published up to November 2021 were identified from the databases of MEDLINE, Cochrane and Web of Science. We also browsed the proceedings of leading international conferences (e.g., ACL, COLING, Interspeech, LREC) from 2017 to 2021, and checked the reference lists of relevant studies and reviews. Main Contribution: The paper provides an introductory, but complete, overview of the application of NLP techniques for studying language disruption due to dementia. We also suggest that this technique can be fruitfully applied to other medical conditions (e.g., cognitive dysfunctions associated with dysarthria, cerebrovascular disease and mood disorders). Conclusions & Implications: Despite several critical points need to be addressed by the scientific community, a growing body of empirical evidence shows that NLP techniques can represent a promising tool for studying language changes in pathological aging, with a high potential to lead a significant shift in clinical practice.
