1 Introduction
2 Background
2.1 Learning skills of generation Z students
-
Ability to perceive large flows of digital information, such as electronic, audio or video information
-
Habit of consuming large amounts of fragmentary information from social networks without reflecting on whether it is fake or tendentious information
-
Immediate perception of fragments of information dispersed in the flow, and subsequent interpretation of them as if it were a coherent speech
-
Strong preference for high-speed visual perception of information at a superficial level, without awareness of deep content
-
Predominance of concrete thought over abstract thought, with a preference for non-textual information
-
Ability to flow naturally from a real environment to a virtual one and vice versa,
-
Lack of development of reflective plans based on critical thinking, and weak ability to draw conclusions and consider consequences
-
Difficulties in comprehensive analytical perception and logical understanding of phenomena and their relationships
-
Minimalism of the lexical corpus and limitations of oral communication
2.2 Cognitive process and creative thinking
2.3 Traditional creativity model
2.4 Traditional criticality model
2.5 Proposed approach: creativity in criticality
3 Methodology
3.1 Participants and procedure
3.2 Instrumentation
4 Results
4.1 Experimental design
4.2 Examples of experiences and activities
Type of Experience | Description | Skill to develop |
---|---|---|
Video Essays and Podcasts | Creation of the scripts by the students (review and feedback by the teacher) and subsequent recording, production, and post-production | Creativity in Criticality |
Challenge-based learning | Collaborative experience with experts in industry facilities, energy utilities facilities and technology companies | Taking Risks* |
Supervised Questioning Session | The formulation of the questions must be balanced to ensure the inclusion of convergent and divergent questions in the four knowledge domains of the tiered yard | Embracing Contradictions* |
Dialogue Seminars | Meeting between a small group of students and a mentor during which students read their essays and the whole group shares their experiences | Attentiveness towards different situations* |
Argumentative Panels | Argumentative discourse process in science as part of a repertoire of strategies to support the acquisition of scientific literacy | Self-awareness* |
World Café | Academically rigorous data collection method, with an atmosphere of trust and open discussions among participants | Broad Perspective* |
4.3 Podcasts and video essays recording (including script writing)
-
Analysis of the results of the Pre-Tests, for 101 students from the experimental group, and 72 students from the control group
-
Analysis of the results of the Post-Tests, for the 323 students
-
Analysis of the impact of the Treatment on the development of creative thinking and critical thinking for the 173 students of the experimental group
-
Discussion on the first RQ: What are the learning experiences that develop in Gen Z students their ability to advance in each vector in the stepped playground of their learning?
-
Discussion on the second RQ: What are the most appropriate learning techniques for Generation Z students to develop skills of both creativity and criticality in the subjects of the engineering program?
-
Discussion on the results of the opinion survey answered by the students of the experimental group regarding the experiences of the treatment.

4.6 Treatment impact analysis
-
Regarding the strengthening of creativity and criticality skills, the results agree with those obtained in the works investigated in the literature review, specifically those of Chaikovska et al. [9], Hussein et al. [10], Nissenson et al.[14], and Becerra & Almendra [13], regarding the advantages of training in communication practices and scientific education with tools of the new digital age through podcast channels. Additionally, the data suggests a high motivation with the use of podcasts as a means of instruction in the course.
-
Regarding the efficacy in the use of active and experiential learning techniques related to Challenge-Based Learning, the results showed agreement with the studies by Sgambi et al. [7] and Miller et al. [8], regarding the relevance of interdisciplinary active experiences for Gen Z students to have greater achievements with the “Taking Risks” skill, enhanced metacognitive awareness and personal motivation, appropriate to their personality traits.
-
Regarding the relevance of training with Supervised Questioning Sessions, the results showed a greater understanding of abstract concepts and the development of greater motivation to make cognitive efforts. These results agreed with those obtained by Wu et al. [12] and Qamar et al. [17] related to the strengthening of students in their development of the competence of "Embracing Contradictions" to overcome cognitive biases related to Cognitive Fixation and Premature Closure.
-
Regarding the development of competencies throughout the three semesters of the project, Fig. 15 shows that not all competencies had the same level of strengthening. The competencies that were strengthened the most were, in the first place, Criticality and, in second place, Creativity. These results agreed with those reported by Torres-Gómez et al. [15] and Zúñiga-Robles & Truyol [77], since the improvements in the effectiveness of the approach were made possible by the instructional strategy, especially the discussions and interactive sessions, which were designed to include aspects of critical thinking and creative thinking, as explained in the previous sections.
