ABSTRACT

Critical thinking is one of the key skills we apply in dealing with an increasingly complex society. The advent and spread of the Internet and artificial intelligence has further increased the need for human beings, especially young people, to develop critical thinking skills. University students study, communicate, and entertain themselves using the Internet in a variety of ways. It would be interesting to ascertain to what extent evaluating information on the Internet can help young people develop a more robust critical thinking disposition. Given the lack of studies on this subject, we aimed to analyse whether behaviours such as netiquette and discernment of the reliability of online information, both of which require users to assess information on the Internet, predict critical thinking disposition, allowing for differences among genders. A total of 415 pre-service teachers aged between 17 and 36 participated. Using multiple linear regressions, our results show that discerning the veracity of online information, especially in men, and netiquette, especially in females, predict critical thinking disposition. We discuss educational implications, especially for future teachers.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

RESUMEN

Una de las competencias clave para desenvolverse en un mundo cada vez más complejo es el pensamiento crítico. La irrupción de internet y de la inteligencia artificial ha potenciado aún más la necesidad de desarrollar la disposición al pensamiento crítico, especialmente entre los jóvenes. Los chicos y las chicas en la universidad estudian, se comunican y se divierten utilizando internet, aunque lo hacen de manera diferenciada. En este sentido, sería interesante conocer en qué medida evaluar la información en internet puede facilitar el desarrollo de una disposición al pensamiento crítico más estable. Dada la ausencia de estudios que lo valoren, el objetivo de esta investigación es analizar si conductas como evaluar la fiabilidad de la información en línea y la netiqueta, ambas requieren valoración de la información en internet, predicen la disposición al pensamiento crítico y además, de forma diferenciada según el sexo. Participaron 415 estudiantes de Magisterio con edades entre 17 y 36 años. A través de regresiones lineales múltiples, los resultados muestran que la evaluar la veracidad de la información en línea, especialmente en los chicos, y la netiqueta, especialmente en las chicas, predicen la disposición al pensamiento crítico. Se analizan las implicaciones educativas, especialmente en futuros docentes.

1. Introduction

1.1 Attitudes toward critical thinking

Our current society is characterised by hypercommunication, immediacy, and the emergence of post-truth in the social fabric (Gozálvez-Pérez et al., 2022). To navigate such challenges effectively, citizens need to acquire increasingly complex competencies. One of these is critical thinking, a construct gaining increasing relevance and attracting growing research interest. Initially, Ennis (1987) defined critical thinking as “reasonable, reflective thinking that is focused on deciding what to believe or do.” Along similar lines, Kuhn (1991) stated that critical thinking consists of reasoned arguments that should help people face life’s challenges. Following those two authors’ initial contributions, the theory of critical thinking has become further enriched by incorporating essential concepts, including the differentiation of opinions on the one hand and evaluating statements on the basis of proof on the other (Facione, 1990; Jiménez-Aleixandre, 2010). Certain authors explain critical thinking as a cognition-related ability to analyse, evaluate and infer, while others describe it as a disposition associated with open-mindedness, truth-seeking, and a systematic approach that enables users to confront challenges and make decisions in daily life (Facione et al., 2002; Halpern & Dunn, 2021; Liu et al., 2024).

We focused our present study on critical thinking disposition, an aspect certain authors have regarded as essential in the overall construct (Poondej & Lerdpornkulrat, 2015). Researchers have associated critical thinking disposition with several variables, including academic level, scientific creativity (Fernández-Vilanova & Solaz-Portolés, 2022; Frisby, 1991), resilience (Cieza & Palomino, 2020), academic performance (Ren et al., 2020), and flexible, fluid thinking (Liu et al., 2024). A further research team found that reflective learning and participation in high-impact activities is directly and positively associated with critical thinking disposition (Álvarez-Huerta et al., 2023). Other studies have investigated the influence of age group, noting that critical thinking disposition steadily increases during childhood and adolescence (Frisby, 1991). Casas & Ceñal (2005) found that from the age of thirteen on, adolescents’ modes of thinking start to become more abstract; whenever they are searching for solutions, they increasingly display a capacity for criticism and discussion.

However, no study has found evidence that men and women might have different patterns in their critical thinking disposition (Cieza & Palomino, 2020; Fernández-Vilanova & Solaz-Portolés, 2022; Kawashima & Shiomi, 2007). However, a reduced number of studies have focused on dimensions including confidence in reasoning and formulating judgments, finding that men seem to have a slight advantage in these aspects (Escurra & Delgado, 2018).

Several research teams have investigated the possibility of teaching critical thinking (Afshar & Rahimi, 2014; Gormley, 2017; Halpern, 2013). In higher education, there is a reigning consensus that students’ critical thinking ability and critical thinking disposition are key competencies that should be reinforced in the course of their university training (Davies & Barnett, 2015); other authors have highlighted the need to improve pre-service teacher training in this area (Lithoxoidou & Papadopoulou, 2024). Given that the Internet has become an essential component of university students’ academic and social life, it has become crucial for them to approach Internet content with a disposition toward critical thinking. “Critical thinking disposition” has thus become one of the most formidable current academic challenges (Santisteban et al., 2020).

1.2 Competencies in evaluating aspects of netiquette and the discernment of reliability of online information.

Two of the competencies established by the European Union in its DigComp framework are 1) information and data literacy and 2) communication and collaboration (Vuorikari et al., 2022). The same EU document foresaw the development of these competencies in pre-service teachers so that they might later apply them in the classroom (Cisneros Barahona et al., 2023).

The first of the two competencies, “information and data literacy,” involves navigating and searching the Internet, filtering data, and evaluating the reliability of digital information. Moreover, it involves the capability to store, organise, and retrieve information (Ministerio de Educación y Formación Profesional, 2022). The characteristics of our current information and communication society imply that individuals are continually confronted with a vast quantity of information (Kelly et al., 2019; Zenali et al., 2019) and with ongoing technological innovations. The increasing influence of artificial intelligence implies that information can be more easily manipulated and falsified; this, in turn, considerably influences Internet users’ attitudes and positions (Gil-Fernández & Calderón-Garrido, 2021). Thus, evaluating the reliability of online information has become an essential tool (Bronstein et al., 2019; Cuesta & Espitia, 2020; Jiménez Rojo, 2020). Various authors have pointed out the need for university students to acquire it (Cabero-Almenara et al., 2023; Silva Quiroz et al., 2023); therefore, it has particular relevance for future teachers.

Another subcompetency in the area of digital communication and collaboration is netiquette, a habitual online behaviour that also requires the user to judge and evaluate online information. Netiquette is the set of civilised norms and behaviours that allow an individual to use the Internet appropriately (Shea, 1994). This implies that people treat one another respectfully on social media, showing regard for each user’s privacy and endeavouring to create a positive online atmosphere (Flores, 2010). This requires them to evaluate the form, the content, and the reliability of transmitted information in order to ensure that users respect one another (Cebollero-Salinas et al., 2022a). As a subcompetency, netiquette brings several benefits, including the mitigation of antisocial behaviour (Ang, 2015), bullying, and cyberbullying (Kumazaki et al., 2011). Further studies on the relationship between netiquette and online risks, such as Internet abuse, have concluded that netiquette acts as a protective factor, especially for females (Yudes-Gómez et al., 2018; Cebollero-Salinas et al., 2021). Sex can be a differentiating factor, as women achieve higher netiquette scores than men (Cebollero-Salinas et al., 2021 & 2022a). Studies on netiquette have focused on describing guidelines that guarantee satisfactory communication (Brusco, 2011; Hammond & Moseley, 2018), for instance, in student-teacher online interactions (Arouri & Hamaidi, 2017; Linek & Ostermaier-Grabow, 2018). To date, no study has analysed to what extent netiquette might be a factor that predicts critical thinking disposition.

Studies on the relationship between critical thinking and information/data literacy are scarce; moreover, these two variables have not been analysed from the perspective of netiquette. In their systematic review on the subject of critical thinking and social networks in the field of education, Escribano-Muñoz et al. (2024) found that most studies applied a qualitative methodology and focused on didactic uses of social networks to encourage critical thinking, as well as on strategies for the critical evaluation of content published on social media, such as memes (Camas et al., 2018). A reduced number of studies applied a theoretical approach (Riser et al., 2020). Adopting an evolutionary perspective, Pérez-García & López-Martínez (2024) found that adolescents apply critical thinking to discern risky online fake news content more frequently as they grow older. However, no study has investigated such variability in association with the factor of sex or gender.

In sum, the Internet has clearly become an essential part of university students’ academic and social life. In this context, netiquette and literacy in assessing the reliability of online information are key skills for dealing with increasingly frequent phenomena such as privacy protection and online disinformation (Arcila Rodríguez et al., 2022; Escribano-Muñoz et al., 2024). It has thus become increasingly necessary to launch new lines of research on these subjects, particularly in population groups of adolescents and young adults (Figuera-Avellán, 2022; Fonseca, 2020). Until now, research articles have mainly tended to analyse concrete didactic projects focusing on the use of social networks to encourage critical thinking; however, there is still a lack of studies on the extent to which certain habitual behaviours applied in evaluating online information (such as netiquette and literacy regarding the reliability of such information) can further the development of a more robust critical thinking disposition. Thus, our study aimed to examine the predictive capacity of those two variables (netiquette and information literacy) for university students’ critical thinking disposition, expecting that the insight thereby gained would open concrete possibilities for future educational projects, particularly with pre-service teachers. We chose to analyse differences according to sex, given that females and males have different motivations for using the Internet and social media (Twenge & Martin, 2020).

Our work hypotheses were the following:

1) Netiquette and data/information literacy (regarding the reliability of online information) are predictors of critical thinking disposition.

2) Differences between the sexes will be notable, given that netiquette has a greater predictive capacity in women for other online behaviours. (We did not anticipate the weight according to sex of the other variable, i.e., data/information literacy regarding reliability, as no studies on that particular aspect had been conducted.)

 

2. Methodology

2.1 Sample

Participants were 415 students from the Faculty of Education of the University of (anonymised) (Spain), ages 17 to 36 (M=19.98 and SD=4.183), of which 299 participants were female (72.2%), and 116 were male (27.8%). The sample was incidental by accessibility.

That substantial difference in proportions of the sexes corresponds to the usual proportion by sex of students enrolled in education studies.

 

2.2 Tools

We applied the Critical Thinking Disposition Scale (CTDS) by Sosu, 2013, adapted to Spanish by Bravo et al., 2020. It consists of 11 items that measure Critical Openness (e.g., “I usually try to think about the bigger picture during a discussion”) and Reflective Scepticism (e.g., “I often re-evaluate my experiences so that I can learn from them”), two components of critical thinking disposition. Each item was scored on a Likert-type 5-point scale (1 = Totally agree; 5 = Totally disagree). In the present sample, the internal consistency of scores on this scale (Cronbach's α) was .86.

Specifically for this study, we designed the Evaluation of Reliability of Online Information Competency Scale (“Escala Competencia evaluación de la fiabilidad de la información en línea,” abbreviated as e-CEI). It consisted of a questionnaire that evaluated Internet users' knowledge, skills, and attitudes to evaluate the reliability of information they search for, receive, or share online. To develop this questionnaire, we based ourselves on a series of criteria indicating digital competency in teachers (Ministerio de Educación y Formación Profesional, 2022) and on the main strategies enumerated by the Spanish National Cybersecurity Institute (INCIBE) for the verification of information. The e-CEI questionnaire consists of eight items featuring six response options ranging from 1= never to 6=always (e.g., “Before forwarding a video or comment I have viewed, I stop to check its veracity”). Confirmatory factorial analysis (CFA) yielded a one-factor solution and optimum data fit: (CFI)=.994; (TLI)=.992; RMSEA=.101); AVE= .567. This scale thus has high internal consistency (Cronbach’s α=.916).

Netiquette. A subscale of the questionnaire “Evaluation of cyberbehaviour quality” (Evaluación de la calidad de la ciberconducta «EsCaCiber») (Ortega et al., 2012), designed as a measurement scale in adolescents. The netiquette subscale consists of four Likert-type items with five frequency responses (ranging from 0=never to 4=always) regarding respect for fellow users and protecting their privacy when evaluating online information (e.g., “Before I publish something by someone else, I ask them for permission”). In our study, this scale’s reliability index was α = .80.

 

2.3 Procedure

The university students completed the battery of questionnaires, which were placed at their disposal on an online platform. User anonymity and answer confidentiality were guaranteed. Ethical standards established in the Helsinki Declaration (World Medical Association, 2013) were respected: these included voluntary participation and providing free, informed consent for the use of participant data for research purposes while also informing participants that they could choose to opt out at any moment of the questionnaire. Data were treated confidentially, respecting participants’ privacy.

 

2.4 Data analysis

We conducted a univariate descriptive analysis of the sample to ascertain participants’ sociodemographic profiles and scores for the study variable. First, we applied the Kolmogorov-Smirnov test to analyse the normal data distribution. Although the results showed a non-normal sample, we used parametric tests, as with sample sizes larger than thirty individuals, the distributions of means tend to approximate a normal distribution, and it is thus possible to use parametric statistical techniques (Box et al., 1988). We thus proceeded to conduct a descriptive analysis of the study variables by applying a one-way ANOVA to analyse significant differences according to sex. In cases that did not fulfil the assumption of equal variance, we applied the Brown-Forsythe test. We also calculated effect size (η). Subsequently, we applied bivariate correlation (Pearson's r) to analyse relationships among variables. In a last step, we applied multiple linear regression to analyse the variables’ capacity to predict critical thinking disposition (Pardo & Ruiz, 2005). We included the age variable, as the age range in our sample was large, and researchers have found that critical thinking increases with age (Casas & Ceñal, 2005). Variables were added in successive blocks to allow us to independently assess the contribution provided by new variables once a previous variable had made its contribution (Block 1: evaluation of online information reliability; Block 2: netiquette; Block 3: current age). SPSS v26 statistical software was used to calculate results.

 

3. Analysis and results

3.1. Statistical descriptives and relationships among study variables according to sex

As shown in Table 1, differences among females and males appeared. Women scored higher on critical thinking and netiquette; however, only the netiquette difference was statistically significant, with a medium effect size (η2= .49). Values were similar in students’ capacity to evaluate the reliability of online information; here, males scored slightly higher, and the difference was statistically significant.

3.2. Correlations

Table 2 displays the relationships among variables according to sex. Critical thinking disposition correlates in both sexes with the two behaviours (netiquette and evaluating online information), yielding medium-high values. In men, the relationship between evaluating online information and critical thinking disposition stands out (.333** vs .384**). The relationship between critical thinking disposition and netiquette in women is likewise notable (.391** vs .216**). The age variable is only related to the other variables in the case of women.

3.3. Variables that predict critical thinking disposition according to sex

Tables 3 and 4 gather the results of our linear regression analysis differentiated according to sex. The study variables predict 27% of critical thinking disposition in women and 23% in men. In both cases, evaluating online information is the factor with the strongest predictive capacity (15% in women and 20% in men), followed by netiquette (9% in women and 3% in men).

4. Discussion

Aiming to open new lines of research to help educational institutions deal with current challenges, our study examined whether the subcompetency of netiquette and the capacity to evaluate the reliability of online information predict critical thinking disposition in pre-service teachers, differentiated according to sex.

Our descriptive results suggest that critical thinking disposition reaches similar levels in male and female university students. These findings are in line with previous investigations that found no differences, in terms of sex, in rates of critical thinking disposition (Cieza & Palomino, 2020; Fernández-Vilanova & Solaz-Portolés, 2022; Kawashima & Shiomi, 2007). Neither did we find differences in the competency of evaluating online information reliability: this is a new finding, given the absence of previous research on sex differences in this domain. However, in line with previous studies featuring samples of adolescents (Cebollero-Salinas et al., 2021 and 2022), we found that female university students attained higher levels of netiquette: in other words, they evaluate online information to communicate respectfully with other users while protecting those users’ privacy (Flores, 2010). Certain studies have explained this phenomenon by suggesting that girls spend more time on social media, implying that they are more accustomed to considering and applying respect for other users’ privacy (Díaz-López et al., 2020; Joiner et al., 2012; Tifferet, 2019).

Our bivariate correlation analysis suggested that critical thinking disposition correlated with the two online-information-related competencies (netiquette and evaluating reliability) in both sexes. This is in line with certain previous studies on critical data/information literacy, which have found that it is related to an improved capacity to analyse the news and to an enhanced critical thinking capacity to evaluate socially relevant problems (Castellví et al., 2020; Santisteban et al., 2020; Šuminas & Jastramskis, 2020). It is likewise notable that the evaluation of online information reliability only correlated with netiquette and age in our female participants. One explanation could be the greater amount of time spent by girls/women on social networks (Twenge & Martin, 2020), which can lead them to evaluate a greater quantity of information overall. Thus, either by trial and error or by gradually developing awareness, they would develop an improved capacity to discern flaws and inconsistencies in the online information they view. As age advances, they evaluate risks more frequently and become more capable of assuming risky challenges despite eventual consequences (Elboj et al., 2023; Pérez-García & López-Martínez, 2024).

Our exploration of the variables’ predictive capacity showed that the two variables, netiquette and the evaluation of online information reliability, predicted critical thinking disposition in both sexes. Our first hypothesis was thereby confirmed. This might imply that concrete actions can encourage critical thinking in its most robust form. Age plays a predictive role in women; in other words, female students studying in the last two years toward a primary school teaching degree are more prone to develop a critical thinking disposition. This might be explained by women’s more rapid maturing process compared to men (Galdó-Muñóz, 2007).

In men, the variable with the strongest predictive capacity was the competency to evaluate the reliability of online information. In women, conversely, the variable with the strongest predictive capacity was netiquette. This result aligns with previous studies that reported a greater predictive role of netiquette in girls (Cebollero-Salinas et al., 2022a). This confirms our second hypothesis and provides new evidence in this domain.

These results have relevant educational implications. They highlight the importance of netiquette and evaluating the reliability of online information in encouraging the development of critical thinking in students studying toward a primary school teaching degree. Primary school teachers frequently need to assess the reliability of online information, for instance, when preparing didactic units for class. As they learn to communicate and collaborate online with colleagues and families, they must be trained to deal with problematic situations requiring efficient solutions. Our results open new research paths in searching for ways to encourage these pre-service trainees to develop their critical thinking.

Teachers must also know how to encourage the evaluation of online information to improve harmonious coexistence in educational centres, in face-to-face and online situations. This requires students to follow adequate netiquette standards; meanwhile, teachers should design activities that help schoolchildren learn this competency (Cebollero-Salinas et al., 2022a). As netiquette is related to emotional competencies, it can thus be featured in didactic units that feature socio-emotional competencies and encourage harmonious coexistence in school (Cebollero-Salinas, 2022c y 2024).

Several studies in Spain have found that only a minority of pre-service teachers studying toward a primary school teaching diploma (Magisterio) tend to use critical thinking to verify information, analyse proposals, and state their opinions (Castellví et al., 2020; Santisteban et al., 2020). It is thus urgent to educate them further in this domain. Universities should position themselves as a learning environment that encourages collective reflection, preparing citizens to face the challenges that await them online (Mesquita-Romero et al., 2022). Research articles on data/information literacy in education have highlighted the need for institutions to assume leadership in such actions, promoting a culture of information literacy with research projects that focus on the relationship between information literacy and its pedagogical, didactic, and curricular components; this, in turn, will help to consolidate educational policies (Arcila Rodríguez et al., 2022).

Our results should be taken into account, considering our study’s limitations. We obtained our data from self-report responses to a questionnaire, which can lead to response desirability bias. Future research along these lines would require incorporating qualitative data and other information sources. Moreover, our sample was gathered in terms of accessibility, and the proportion of women was considerably greater than that of men, reflecting actual enrolment in Primary Teacher Diploma studies (Grado de Magisterio). To generalise results across the entire university student population, this study would need to be replicated with an equitable distribution by sex, and the sample would need to be randomised. It would also be interesting to ascertain whether our findings on critical thinking disposition are reflected in similar tendencies if we measure critical thinking abilities per se.

Despite these limitations, our study provides certain novel contributions. On the one hand, it provides evidence that the concrete behaviour of evaluating online information can increase and support critical thinking in its more robust state. Netiquette reveals itself as a further channel for encouraging critical attitudes, and differences appear between young men and young women in predicting critical thinking disposition; all these aspects need to be considered.

We conclude by highlighting the relevance of certain concrete competencies in young people’s disposition when they use the Internet and navigate social networks, namely, netiquette and the capacity to evaluate the reliability of online information. Both of these competencies can work in favour of university students’ critical thinking disposition. This opens up avenues to work on the challenges posed by the generalised use of artificial intelligence (AI) to the critical thinking abilities of future teachers and their capacity to transfer such critical thinking disposition to the classrooms where they exercise their teaching profession.
