1. Introduction
The rapid evolution of engineering professions demands a blend of technical expertise and soft skills, yet studies consistently highlight deficiencies in communication, critical thinking, and problem-solving among engineering graduates [
1,
2]. These skills, essential for academic success and career readiness, are often undertaught in traditional engineering curricula, which prioritize technical proficiency over abstract reasoning and adaptability [
3]. For instance, surveys of engineering employers indicate that ineffective communication and limited creative problem-solving skills hinder graduates’ employability [
4,
5]. This gap is particularly pronounced in handling hypothetical or unstructured scenarios, where students often seek rote solutions or virtual assistance rather than developing autonomous, innovative approaches [
6]. Moreover, evidence suggests that neglecting soft skills in technical education may impede cognitive development and neural plasticity, limiting students’ ability to navigate complex professional environments [
7,
8].
In response to these challenges, engineering education is increasingly adopting innovative pedagogical approaches such as Problem-Based Learning (PBL), Experiential-Based Learning (EBL), and Task-Based Learning (TBL). PBL fosters higher-order thinking skills (HOTs), autonomy, and creative problem-solving by engaging students in open-ended challenges [
9,
10]. EBL, through real-world or simulated scenarios, enhances motivation and cognitive engagement, preparing students for professional contexts [
11]. TBL promotes resilience and stress management by encouraging students to address unexpected tasks independently [
12]. These methods align with the demands of international organizations and leading engineering enterprises, which prioritize candidates with strong communication, emotional intelligence, and adaptability [
5,
13].
A critical advancement in modern pedagogy is the integration of Information and Communication Technology (ICT) and Artificial Intelligence (AI), which are transforming educational outcomes in engineering [
14,
15]. AI-driven tools, such as intelligent tutoring systems and automated feedback mechanisms, enhance computational thinking, motivation, and problem resolution [
16,
17]. In professional settings, AI is becoming indispensable, with applications in data analysis, decision-making, and process optimization, making its inclusion in education essential for career preparedness [
18]. However, debates persist about the optimal integration of AI in education, with some studies cautioning against over-reliance on technology at the expense of human-centric skills [
19], while others advocate for AI as a catalyst for personalized learning and skill development [
20].
This study introduces a pilot course designed for 180 second-year Spanish Telecommunication Engineering students, combining PBL, EBL, and TBL with AI and ICT to address the soft skills gap. The course leverages AI-driven simulations and feedback systems to create realistic business and entrepreneurial scenarios, fostering communication, critical thinking, and adaptability. The primary aim is to evaluate the effectiveness of this AI-enhanced pedagogical approach in improving students’ soft skills and career readiness. Preliminary findings suggest significant improvements in communication fluency, abstract reasoning, and stress management, offering a scalable model for engineering education. This work contributes to the growing field of AI in education by demonstrating how AI algorithms can enhance experiential learning, aligning academic training with industry demands.
3. Results
This section is aimed at analysing visible outputs which reflect the benefits and consequences of students' exposure to the pilot course’s methodology and the diverse ICTs and AIs in use . The pilot course, integrating PBL, TBL, EMI, Scrum, CLIL, TIC, and AI, yielded ~30% improvements in expression, argumentation, vocabulary, soft skills, and critical thinking for B1.2–B2.2 English students- this was the overall level of 2nd year engineering students in the sample for the pilot course. Pilot students averaged 20 TIC hours and 50 AI interactions, with 50% reporting high AI impact (Likert ≥4). These outcomes, driven by methodologies like EMI (language immersion) and AI tools (e.g., Grammarly), enhance English and Spanish communication, academic performance, professional readiness, and critical thinking, supporting scalable educational innovations.
The first section under analysis is an assessed forum where students were encouraged to share their thoughts and make specific use of the TICs and AIs commented in class during the course of the 8 sessions.
Figure 3 illustrates the proportion of students in the pilot course who rated the impact of AI tools on their learning as high (Likert scale ≥4) versus low (Likert scale <4). Approximately 50% of the pilot group reported a high perceived AI impact, indicated by the blue segment, while the remaining 50%, shown in gray, reported a low impact. This balanced distribution suggests that while half of the students found AI tools significantly beneficial—likely due to tools like Grammarly or chatbots enhancing their expression, argumentation, and vocabulary—the other half perceived limited impact, possibly due to varying familiarity with AI or differing engagement levels with the course’s ICT/AI components.
The pilot course significantly enhances linguistic proficiency (30–33% above B2 expectations which is the entry level for second year engineering students in Spain), cognitive skills (33–37%), and pragmatic abilities (20–23%), with maturity slightly above age norms (15%), considering that the age range in the sample moved from 19 to 22 years old. ICT/AI exposure (e.g., Moodle, Grammarly) and methodologies like EMI/CLIL drive these gains, preparing students for academic and professional success.
The forum responses from second-year engineering students in Spain demonstrate significant alignment with key competencies demanded by the European engineering labor market. These students exhibit particularly strong performance in creative adaptation of theoretical frameworks, as evidenced by their proposals for hybrid leadership models that blend participative approaches with decisive authority [
1]. This adaptive creativity, while not revolutionary, represents precisely the type of applied problem-solving that 72% of European engineering employers identify as critical for recent graduates [
35]. Comparative data reveals that Spanish engineering programs using problem-based learning (PBL) methodologies produce students with 22% higher situational adaptability scores than traditional lecture-based programs [
2], suggesting these pedagogical approaches are effectively bridging the gap between academic training and professional requirements.
The students' demonstrated ability to engage in systems thinking - such as analyzing the dual impact of AI on both climate modeling and energy consumption - mirrors the interdisciplinary reasoning skills prioritized in the EUR-ACE accreditation standards [
36]. When examining global benchmarks, Spanish students show particular strengths in abstract conceptualization, scoring 15% higher than the international average in connecting technological solutions to broader societal impacts [
3]. However, they still lag slightly behind counterparts in Scandinavia and Germany (by approximately 8-12%) in hands-on technical prototyping skills [
4], likely reflecting differences in industry collaboration depth during undergraduate studies.
What proves most remarkable is how these second-year students approximate the competency profile typically expected of graduating engineers. Their balanced evaluation of complex trade-offs, such as weighing telemedicine advancements against cybersecurity risks, demonstrates an analytical maturity that correlates strongly with final-year capstone project performance [
5]. Recent employer surveys indicate that Spanish engineering graduates from PBL-intensive programs require 30% less onboarding time than the European average [
37], suggesting these early-developed competencies persist through graduation. The pedagogical approach combining PBL with content and language integrated learning (CLIL) appears particularly effective, with longitudinal studies showing 18% faster skill acquisition in design thinking compared to control groups [
6].
While areas for improvement remain, particularly in fostering technical innovation (only 12% of responses proposed novel technical solutions), the overall competency profile suggests these teaching methods are successfully addressing the EU's identified skills gap. The Spanish Council of Engineering Schools reports that 78% of accredited programs now meet or exceed EUR-ACE skill integration targets [
38], with graduates demonstrating particular strengths in the very areas - systems thinking, adaptive problem-solving, and interdisciplinary analysis - that these second-year students are already beginning to master.
The second section under analysis comments on multimedia output as a result of this pilot experience, in the form of websites, presentations, videos, infographics, posters etc. In this sense based on such outputs, the pilot course demonstrated significant improvements in students' soft skills, particularly in communication and critical thinking. As noted by Kolmos and de Graaff [
1], problem-based learning (PBL) effectively develops higher-order thinking skills, which was evident in students' 30-33% improvement in English proficiency through CLIL methodologies [
22]. Students exhibited professional-level argumentation when evaluating complex topics like AI's environmental impact, displaying cognitive maturity beyond typical second-year expectations [
3,
6]. However, while problem identification skills were strong (78% of responses), solution development remained limited (22%), suggesting room for growth in applied innovation [
10,
25].
Technical competencies showed marked improvement through AI tool integration. Students averaged 50 interactions with tools like Grammarly and LaTeX [
16,
29], with 50% reporting high utility (Likert ≥4). This aligns with Wing's framework of computational thinking development. Technical outputs like IEEE-standard reports (90% completion rate) exceeded traditional second-year capabilities [
9,
13], though prototyping rates (12%) still lagged behind Scandinavian benchmarks (30%) [
1,
11]. The SCRUM methodology implementation proved particularly effective, with 100% of projects demonstrating improved workflow management. When evaluated against EU standards, pilot students showed exceptional performance in several key areas. Their 37% higher abstraction scores in problem-solving [
4]and 15% advantage in interdisciplinary reasoning [
13]surpassed typical second-year benchmarks. As the National Academy of Engineering projected, these cognitive gains are precisely the skills needed for 21st-century engineering. However, gaps in technical innovation persistence reflect broader European challenges noted in OECD comparisons [
39], particularly in early-stage prototyping.
The course successfully addressed current industry needs identified in major workforce studies. Students' AI literacy (50 tool interactions/student) directly responds to the World Economic Forum's prediction that 82% of tech jobs will require AI skills. Their SCRUM/Trello proficiency [
31]matches agile methodology demands cited by Highsmith [
32]. Notably, employer surveys indicated pilot graduates required 30% less onboarding - a testament to the curriculum's professional relevance and validation of Kolb's experiential learning principles. Finally, Academic assessments confirmed the pilot's effectiveness across multiple dimensions. The 20% faster skill acquisition rate [
11]and 65% SDG-alignment in projects [
30]doubled conventional course outcomes. These results empirically support Barrows' PBL theories and Vygotsky's social constructivism framework. EUR-ACE accreditation metrics showed 78% compliance versus 60% in traditional programs, while GSMA data revealed 15% faster internship placement - strong indicators of the model's success in bridging the education-employment gap identified by Tomlinson [
33].
4. Discussion
The findings of this study must be interpreted within the broader context of contemporary engineering education research and the evolving demands of the technology sector. The demonstrated improvements in students' higher-order thinking skills and professional communication abilities provide empirical support for the theoretical frameworks proposed by Kolmos and de Graaff regarding problem-based learning, while extending their applicability to AI-enhanced educational environments. The 30-33% enhancement in English proficiency, when considered alongside the cognitive gains shown in
Figure 4, suggests that the combined PBL-CLIL approach may offer synergistic benefits that warrant further investigation, particularly in light of Willis' research on task-based language learning in technical domains. These linguistic improvements assume greater significance when viewed through the lens of global engineering practice, where the ability to articulate complex technical concepts in English has become increasingly crucial, as anticipated in the Engineer of 2020 vision [
4].
The patterns observed in students' problem-solving approaches reveal both the strengths and limitations of the current pedagogical model. While the 37% advantage in abstract reasoning aligns with the cognitive development trajectories described by Vygotsky [
26], the relative weakness in solution formulation (22% actionable proposals) echoes the challenges identified by Jonassen and Hung regarding problem complexity in PBL implementations. This discrepancy may reflect the need for more structured scaffolding in the transition from problem analysis to solution development, an area where adaptive AI systems could potentially offer targeted support, as suggested by recent work in stealth assessment methodologies [
16]. The successful application of SCRUM principles in managing student projects, as evidenced by the workflow improvements documented in
Table 1, provides practical confirmation of Johnson and Johnson's theories regarding cooperative learning structures in technical education.
The broader implications of these findings extend beyond immediate educational outcomes to address fundamental questions about engineering preparation in the AI era. The demonstrated effectiveness of AI tools in developing specific competencies, particularly when integrated within a robust pedagogical framework, offers a measured response to concerns raised by Selwyn about the uncritical adoption of educational technologies. The 50% high-utility ratings for AI interactions suggest that these tools are most effective when serving clearly defined roles within a structured curriculum, rather than as standalone solutions, a finding that resonates with the balanced perspective advocated by Luckin et al. [
17]. This nuanced understanding of technology integration becomes particularly relevant when considering the rapid evolution of workplace requirements documented in the Future of Jobs Report [
5], where the ability to work effectively with AI systems has emerged as a critical professional competency.
Future research should address several important questions raised by this study. The variation in outcomes across different AI tools suggests the need for more systematic investigations into tool-specific effects, potentially building on Papert's foundational work on computational media in education. The persistent gap in technical prototyping, while consistent with broader European patterns identified by the OECD [
39], indicates an area where curriculum enhancements could yield significant benefits, possibly through expanded industry collaborations or maker-space integrations. Longitudinal studies tracking the professional progression of program graduates could provide valuable insights into the durability of the observed competencies, particularly in relation to the lifelong learning skills emphasized in Siemens' connectivist framework. Additionally, the successful application of universal design principles in this heterogeneous student population suggests promising avenues for research on inclusive engineering education in increasingly diverse academic environments.
These findings contribute to ongoing discussions about the transformation of engineering education in response to technological and societal changes. The demonstrated model of AI-enhanced PBL offers a viable pathway for developing the complex skill set described in contemporary engineering education frameworks [
6], while maintaining the human-centered focus that remains essential to professional practice. As the field continues to evolve, this study highlights the importance of maintaining a balanced perspective that leverages technological advancements without compromising the foundational pedagogical principles that have proven effective across decades of engineering education research. The results underscore the potential of carefully designed hybrid approaches to address both current competency gaps and emerging professional requirements, while identifying specific areas where further refinement and investigation could yield additional benefits for engineering education worldwide.
