I. Introduction

Language education at the tertiary level plays a vital role in equipping students with the necessary language skills and competencies to succeed academically and professionally in an increasingly globalized world. As language educators, it is crucial to continuously explore effective instructional approaches that promote meaningful language learning experiences and foster students' cognitive development (Language Journal, 2020). One such approach that has garnered significant attention in recent years is task-based instruction (TBI).

TBI is a pedagogical framework that places tasks at the center of the language learning process, emphasizing learners' engagement in authentic and purposeful language use. Drawing on the works of Van Den Branden (2020), García Mayo and Lavid López (2020), Van Den Branden, Michel, and Bruton (2020), Thomas and Reinders (2020), and Moeller, Gibbons, and Castro (2021), TBI encompasses a range of task types, such as problem-solving activities, simulations, and collaborative projects, designed to elicit language production and facilitate language learning in meaningful contexts.

The transformative power of TBI lies in its potential to unlock learners' cognitive abilities and enhance their overall language proficiency. According to Van Den Branden (2020), TBI promotes active engagement, critical thinking, and problem-solving skills, all of which are crucial for academic and professional success. This approach aligns with the constructivist perspectives highlighted by Van Den Branden and Medgyes (2020), emphasizing learners' active construction of knowledge through authentic, real-world tasks.

As language educators, it is essential to delve into the transformative power of TBI in the context of tertiary language education. By exploring the cognitive potential unleashed through TBI, we can gain valuable insights into the ways in which learners' attention, memory encoding and retrieval, problem-solving abilities, and metacognitive awareness are developed and enhanced. Such exploration can inform pedagogical practices and instructional design, contributing to the creation of transformative learning experiences that prepare students for the complex language demands they will encounter in their academic and professional lives.

In light of the aforementioned considerations, this study aims to investigate the transformative power of TBI in tertiary language education. By examining the cognitive processes and outcomes associated with TBI, we seek to shed light on how this instructional approach can optimize language learning and promote the development of transferable skills. Through this exploration, we hope to contribute to the existing body of knowledge on TBI and provide practical recommendations for language educators and curriculum designers in tertiary contexts.

The purpose of this article is to investigate the transformative power of task-based instruction (TBI) in the context of tertiary language education. By exploring the cognitive potential unleashed through TBI, the study aims to examine the impact of this instructional approach on learners' attention, memory encoding and retrieval, problem-solving abilities, and metacognitive awareness. The ultimate goal is to contribute to the existing knowledge on TBI and provide practical recommendations for language educators and curriculum designers in tertiary settings.

In the following sections, we will delve into the theoretical framework underpinning TBI, outline our research methodology, present our findings, and engage in a comprehensive discussion on the implications of the transformative power of TBI in tertiary language education.

II. Theoretical Framework

The theoretical framework of this study encompassed an overview of cognitive theories and their relevance to language learning (Van Den Branden, 2020; García Mayo & Lavid López, 2020; Thomas & Reinders, 2020). These theories included information processing theory, cognitive load theory, and constructivist perspectives (Van Den Branden, Michel, & Bruton, 2020; Moeller, Gibbons, & Castro, 2021). Information processing theory suggests that learners engage in mental processes such as attention, perception, memory encoding and retrieval, problem-solving, and metacognition when acquiring knowledge (Van Den Branden, 2020). Cognitive load theory focuses on the limitations of working memory and how cognitive load affects learning (Thomas & Reinders, 2020). Constructivist perspectives emphasize learners' active construction of knowledge through authentic, meaningful experiences (García Mayo & Lavid López, 2020).

The theoretical framework included task-based instruction (TBI) as a pedagogical approach where tasks served as the central unit of instruction (East, 2020; Shehadeh, 2020; Van Den Branden & Medgyes, 2020). TBI emphasized learners' engagement in authentic and purposeful language use, promoting active learning and meaningful language production (Hall & Le Cornu, 2021; Yilmaz & Kayi-Aydar, 2021). The framework explored the theoretical foundations of TBI as outlined by the cited authors, such as Van Den Branden, García Mayo, Lavid López, and Van Den Branden and Medgyes.

The theoretical framework linked cognitive processes with the principles of TBI (East, 2020; Shehadeh, 2020; Van Den Branden & Medgyes, 2020). It highlighted how cognitive theories and processes, such as attention, memory encoding and retrieval, problem-solving, and metacognition, aligned with and supported the principles of TBI (Hall & Le Cornu, 2021; Yilmaz & Kayi-Aydar, 2021). For example, attention and perception played a role in selecting and focusing on task-relevant information (East, 2020). Memory encoding and retrieval facilitated the retention and recall of language knowledge and skills (Shehadeh, 2020). Problem-solving abilities were essential for completing tasks, while metacognitive awareness supported self-regulation and reflection in task performance (Van Den Branden & Medgyes, 2020).

By linking cognitive processes with the principles of TBI, the theoretical framework provided a theoretical basis for understanding the cognitive potential unleashed through TBI (Hall & Le Cornu, 2021; Yilmaz & Kayi-Aydar, 2021). It laid the groundwork for investigating how TBI promoted and enhanced cognitive development in tertiary language learners, fostering critical thinking, problem-solving skills, and metacognitive awareness. This framework informed the subsequent sections of the study, where empirical data and findings were examined in light of these theoretical perspectives.

V.2. Salient insights

In terms of TBI significance in the tertiary education, the study yielded the following significant points:

A. Task-Based Instruction in Tertiary Language Education:

Task-Based Instruction (TBI) in tertiary language education is an approach that places tasks at the center of language teaching and learning (Van Den Branden, 2020; García Mayo & Lavid López, 2020). It focuses on providing learners with authentic, meaningful language use experiences that mirror real-life situations. TBI emphasizes the integration of language skills and promotes learner autonomy, critical thinking, and problem-solving abilities (Thomas & Reinders, 2020).

B. Definition and Characteristics of Task-Based Instruction:

TBI can be defined as an instructional approach that emphasizes the use of tasks as the main unit of instruction (Van Den Branden, 2020). Tasks are activities that require learners to use language to achieve a specific goal or outcome, such as participating in a group discussion, solving a problem, or completing a project. TBI differs from traditional language instruction by prioritizing the communicative and functional use of language over rote memorization and grammar-focused activities. It emphasizes the importance of meaningful language use and encourages learners to engage in authentic and purposeful communication.

Characteristics of TBI include learner-centeredness, task authenticity, and task complexity (Van Den Branden, 2020; García Mayo & Lavid López, 2020). Learner-centeredness means that learners' needs, interests, and goals are taken into account when designing tasks. Authentic tasks reflect real-world language use situations, ensuring that learners are exposed to language forms and functions they would encounter outside the classroom. Task complexity refers to the cognitive demands placed on learners, with tasks ranging from simple to more challenging, allowing for gradual progression and skill development.

C. Pedagogical Considerations and Approaches in Implementing TBI at the Tertiary Level:

Implementing TBI at the tertiary level requires careful pedagogical considerations (Van Den Branden, 2020; Thomas & Reinders, 2020). TBI is often implemented using a cyclical approach, with pre-task, task cycle, and language focus stages. The pre-task stage involves introducing the task, activating prior knowledge, and preparing learners for the task. The task cycle stage focuses on task performance, allowing learners to engage in meaningful communication while the teacher provides support and monitors progress. The language focus stage provides opportunities for language analysis and feedback, addressing specific language forms and functions that arose during the task performance.

Pedagogical considerations in TBI implementation include task selection, sequencing, and scaffolding (Van Den Branden, 2020; García Mayo & Lavid López, 2020). Tasks should be relevant, engaging, and align with learners' proficiency levels and learning objectives. Sequencing tasks strategically ensures a progression of complexity and linguistic demands. Scaffolding techniques, such as providing models, guiding questions, and peer collaboration, support learners in task completion and language production.

D. Role of Tasks in Promoting Cognitive Engagement and Language Acquisition:

Tasks play a crucial role in promoting cognitive engagement and language acquisition in TBI (Van Den Branden, 2020; Thomas & Reinders, 2020). By engaging learners in authentic, purposeful language use, tasks provide opportunities for meaningful interaction and communication. This engagement stimulates cognitive processes such as attention, memory, problem-solving, and metacognition.

Tasks require learners to use their existing language knowledge and skills in novel contexts, promoting language acquisition and transfer (Van Den Branden, 2020; García Mayo & Lavid López, 2020). They encourage learners to draw upon their linguistic resources, negotiate meaning, and develop communicative strategies. Through active participation in tasks, learners develop fluency, accuracy, and communicative competence.

Moreover, tasks promote cognitive engagement by requiring learners to analyze, evaluate, and make decisions in real-time (Thomas & Reinders, 2020). They foster critical thinking skills, creativity, and problem-solving abilities. As learners engage in tasks, they encounter challenges and find solutions, leading to cognitive growth and metacognitive awareness of their language learning process.

Overall, Task-Based Instruction in tertiary language education revolves around the use of tasks as the main unit of instruction. It emphasizes authentic, meaningful language use and promotes learner autonomy, critical thinking, and problem-solving abilities (Van Den Branden, 2020; García Mayo & Lavid López, 2020; Thomas & Reinders, 2020). Tasks play a pivotal role in promoting cognitive engagement and language acquisition by providing opportunities for authentic communication and cognitive processes (Van Den Branden, 2020; Thomas & Reinders, 2020).

These examples illustrate the diverse range of TBI activities that can be implemented in tertiary language education, covering various topics and drawing from reputable sources to inform and enhance the learning experience.

E. Cognitive Benefits of Task-Based Instruction:

Task-Based Instruction (TBI) in language education offers numerous cognitive benefits to learners. It enhances cognitive processes such as critical thinking, problem-solving, and decision-making (Van Den Branden, 2020; García Mayo & Lavid López, 2020). Through engaging in meaningful tasks, learners are challenged to analyze information, evaluate options, and make decisions in real-time. This cognitive engagement promotes higher-order thinking skills and the ability to apply knowledge and language skills in authentic contexts.

Furthermore, TBI fosters metacognitive awareness and self-regulated learning strategies (Van Den Branden, 2020; García Mayo & Lavid López, 2020). Metacognition refers to learners' awareness and control of their own learning processes. By engaging in tasks, learners reflect on their language use, monitor their comprehension, and evaluate their own performance. They become more conscious of their strengths, weaknesses, and learning strategies, leading to more effective and autonomous language learning.

Moreover, TBI contributes to the development of cognitive flexibility and adaptability in language use (Thomas & Reinders, 2020). Tasks require learners to employ different language forms, functions, and registers depending on the communicative context. This flexibility in language use promotes cognitive flexibility, enabling learners to adjust their language production according to the task requirements and the interlocutors' needs. Learners become more adept at switching between different linguistic resources and adapting their language use to diverse situations.

Overall, Task-Based Instruction offers several cognitive benefits to learners. It enhances critical thinking, problem-solving, and decision-making skills by providing opportunities for authentic language use in meaningful tasks (Van Den Branden, 2020; García Mayo & Lavid López, 2020). TBI fosters metacognitive awareness and self-regulated learning strategies, empowering learners to monitor and control their language learning processes. Additionally, TBI develops cognitive flexibility and adaptability, enabling learners to employ diverse language resources and adjust their language use based on communicative contexts (Thomas & Reinders, 2020).

F. Transformative Nature of Task-Based Instruction

It can be deduced that TBI is totally beneficial in terms of the following:

Empowering learners through authentic and meaningful language tasks: TBI empowers learners by providing them with authentic and meaningful language tasks (East, 2020; Shehadeh, 2020). Engaging in real-life tasks, such as role-plays, problem-solving activities, or project-based assignments, allows learners to apply language skills in meaningful contexts. This empowers learners to take ownership of their learning as they see the immediate relevance and purpose of the language they are acquiring (East, 2020). Through TBI, learners become active participants in the learning process, gaining confidence and motivation to use the language outside the classroom (Shehadeh, 2020).
Promoting learner autonomy and ownership of the language learning process: TBI promotes learner autonomy and encourages learners to take responsibility for their language learning (Van Den Branden & Medgyes, 2020). By engaging in tasks that require decision-making, problem-solving, and self-assessment, learners develop metacognitive and self-regulatory skills (Van Den Branden & Medgyes, 2020). They become aware of their strengths and weaknesses, set their own learning goals, and monitor their progress. This autonomy fosters a sense of ownership and control over the language learning process, leading to more meaningful and sustainable language development (Hall & Le Cornu, 2021).
Cultivating intercultural communicative competence and global perspectives: TBI cultivates intercultural communicative competence and promotes the development of global perspectives (García Mayo & Lavid López, 2020; Yilmaz & Kayi-Aydar, 2021). Tasks often involve collaboration and interaction with peers from different cultural backgrounds, fostering an understanding and appreciation of diverse perspectives (García Mayo & Lavid López, 2020). Through TBI, learners engage in authentic communicative tasks that require them to navigate cultural differences and adapt their language use accordingly. This cultivates intercultural sensitivity and the ability to communicate effectively in multicultural contexts (Yilmaz & Kayi-Aydar, 2021). TBI also encourages learners to explore global issues, fostering a broader awareness of the world and promoting global citizenship.

Overall, Task-Based Instruction has a transformative nature that empowers learners, promotes learner autonomy, and cultivates intercultural communicative competence (East, 2020; Shehadeh, 2020; Van Den Branden & Medgyes, 2020; García Mayo & Lavid López, 2020; Hall & Le Cornu, 2021; Yilmaz & Kayi-Aydar, 2021). By engaging in authentic and meaningful language tasks, learners develop a sense of ownership and motivation in their language learning journey. They also develop the necessary skills to communicate effectively in multicultural settings and gain a global perspective on language use and cultural diversity.

G. Research Findings and Empirical Evidence

Review of empirical studies on the cognitive effects of TBI in tertiary language education: Several empirical studies have examined the cognitive effects of TBI in tertiary language education (Moeller, Gibbons, & Castro, 2021). These studies have consistently shown positive outcomes in terms of enhanced cognitive processes, such as critical thinking, problem-solving, and decision-making (Moeller, Gibbons, & Castro, 2021). Learners engaged in TBI demonstrate improved analytical skills, the ability to evaluate information, and the capacity to make informed decisions in real-life situations (Moeller, Gibbons, & Castro, 2021). These findings highlight the cognitive benefits of TBI and its potential to foster cognitive growth in language learners.

Examination of transformative experiences reported by learners in TBI settings: Qualitative research exploring learners' experiences in TBI settings has revealed transformative experiences (Van Den Branden, 2020; Shehadeh, 2020). Learners report a sense of empowerment and increased confidence in their language abilities as they engage in authentic and meaningful tasks (Van Den Branden, 2020). They also describe a shift in their perspectives, where they develop a deeper understanding of different cultures, gain intercultural competence, and expand their global awareness (Shehadeh, 2020). These transformative experiences indicate that TBI has the potential to shape learners' attitudes, beliefs, and identities as language users.

Discussion of the strengths and limitations of existing research: While research on the cognitive effects and transformative nature of TBI in tertiary language education has provided valuable insights, there are certain strengths and limitations to consider. One strength is the growing body of empirical studies that consistently demonstrate the cognitive benefits of TBI (Moeller, Gibbons, & Castro, 2021). These studies employ various research designs, including quantitative and qualitative methods, providing a comprehensive understanding of the cognitive effects of TBI. However, some limitations include a relatively limited number of longitudinal studies and variations in task design and implementation across studies. Further research is needed to explore the long-term impact of TBI on cognitive development and to establish more standardized approaches to task design and implementation.

Overall, empirical studies have consistently shown the cognitive benefits of TBI in tertiary language education, including enhanced critical thinking, problem-solving, and decision-making skills (Moeller, Gibbons, & Castro, 2021). Learners in TBI settings also report transformative experiences, such as increased empowerment, confidence, intercultural competence, and global awareness (Van Den Branden, 2020; Shehadeh, 2020). However, further research is needed to address limitations and provide a more comprehensive understanding of the cognitive effects and transformative nature of TBI in tertiary language education.

H. Implications for Tertiary Language Education

Recommendations for implementing and optimizing TBI in tertiary language classrooms: To effectively implement and optimize TBI in tertiary language classrooms, several recommendations can be considered (Hall & Le Cornu, 2021). First, it is important to provide clear guidance and training to educators on the principles and strategies of TBI. Educators should be equipped with the necessary knowledge and skills to design and implement task-based lessons effectively (Hall & Le Cornu, 2021). Additionally, promoting collaboration and peer interaction within tasks can enhance the learning experience. This can be achieved through group work, pair activities, and project-based tasks that foster meaningful communication and cooperation among learners (Van Den Branden, 2020). Furthermore, integrating authentic materials and real-world contexts into tasks can create a more engaging and relevant learning environment (Moeller, Gibbons, & Castro, 2021). Overall, careful planning, learner-centeredness, and alignment with curricular goals are essential for successful implementation of TBI in tertiary language classrooms.

Integrating TBI with technology-enhanced learning and digital resources: The integration of TBI with technology-enhanced learning and digital resources offers exciting possibilities in tertiary language education (Thomas & Reinders, 2020). Technology can enhance task design and implementation, providing learners with access to authentic materials, multimedia resources, and online communication platforms (Thomas & Reinders, 2020). Virtual collaboration tools, mobile apps, and online learning platforms can facilitate interactive and engaging task-based activities, promoting communication and collaboration among learners (Thomas & Reinders, 2020). Additionally, technology can support the collection and analysis of learner performance data, allowing educators to provide timely feedback and monitor learners' progress (Thomas & Reinders, 2020). Integrating TBI with technology-enhanced learning can enhance the authenticity and effectiveness of tasks in tertiary language classrooms.

Professional development and support for educators in adopting TBI approaches: Professional development and support for educators are crucial in promoting the successful adoption of TBI approaches in tertiary language education (García Mayo & Lavid López, 2020). Institutions should provide opportunities for ongoing professional development, including workshops, seminars, and collaborative communities of practice (García Mayo & Lavid López, 2020). These initiatives can help educators develop a deeper understanding of TBI principles, refine their instructional practices, and share experiences with colleagues (García Mayo & Lavid López, 2020). Additionally, mentorship programs and peer observations can provide educators with guidance and feedback as they implement TBI in their classrooms (García Mayo & Lavid López, 2020). By investing in the professional development and support of educators, institutions can ensure the successful implementation of TBI and create a positive impact on tertiary language education.

Overall, the implications of Task-Based Instruction (TBI) for tertiary language education involve recommendations for implementing and optimizing TBI in classrooms, integrating TBI with technology-enhanced learning, and providing professional development and support for educators (Hall & Le Cornu, 2021; Thomas & Reinders, 2020; García Mayo & Lavid López, 2020). By following these recommendations, tertiary institutions can create an environment that promotes effective TBI practices, engages learners, and fosters their language development and cognitive growth.

VI. Conclusion

All in all, Task-Based Instruction (TBI) holds significant potential in unlocking learners' cognitive potential and promoting transformative learning experiences in tertiary language education. By engaging learners in authentic and meaningful tasks, TBI enhances critical thinking, fosters metacognitive awareness, and develops cognitive flexibility. It empowers learners, promotes learner autonomy, and cultivates intercultural communicative competence. The findings highlight the importance of implementing TBI in tertiary language education to facilitate cognitive growth and holistic development. Future research should focus on longitudinal studies, standardizing task design and implementation approaches, integrating technology-enhanced learning, and providing teacher professional development and support. Advancements in TBI at the tertiary level can be achieved through collaborative research, sharing of best practices, and ongoing professional development initiatives for educators. Indeed, TBI plays a vital role in unlocking learners' cognitive potential, promoting transformative learning experiences, and shaping the future of tertiary language education.

VII. Implications and Recommendations:

Based on the findings of this study, several implications and recommendations can be made for the implementation of Task-Based Instruction (TBI) in tertiary language education.

First, it is essential to provide comprehensive training and professional development opportunities for language educators to familiarize themselves with TBI principles, instructional strategies, and assessment practices. This will enable them to effectively design and implement TBI activities that promote meaningful language learning experiences.

Second, integrating technology-enhanced learning and digital resources can enhance the effectiveness of TBI. Educators should explore the use of various technological tools and platforms to create authentic and interactive tasks that engage learners and facilitate language acquisition.

Third, fostering collaboration and peer interaction is crucial in TBI. Educators should create a supportive learning environment where students can engage in meaningful communication, collaborate on tasks, and provide feedback to one another. This will enhance their language skills and promote social and cognitive development.

Fourth, incorporating authentic materials and real-world contexts in TBI activities is essential to develop learners' language proficiency and cultural competence. Educators should seek diverse and culturally relevant materials that reflect the interests and backgrounds of their students.

Lastly, ongoing assessment and feedback are integral components of TBI. Educators should implement formative and summative assessments aligned with the objectives of TBI, providing timely feedback to guide learners' progress and inform instructional decisions.

By heeding and implementing these implications and recommendations, teachers, students and stakeholders can optimize the benefits of TBI and create an engaging and transformative learning environment for tertiary language education.
