Higher-order thinking Skills (HOTS) refer to the cognitive processes in which students engage at a higher cognitive level, developed through various cognitive concepts and learning taxonomies such as problem-solving methods, Bloom's taxonomy, and the taxonomy of learning, teaching, and assessment. HOTS encompass problem-solving abilities, creative thinking, critical thinking, reasoning skills, and decision-making skills. According to King, HOTS include critical, logical, reflective, metacognitive, and creative thinking. Meanwhile, Newman and Wehlage state that students who develop HOTS can clearly distinguish ideas, construct well-founded arguments, solve problems effectively, generate explanations, hypothesize, and interpret complex issues more clearly. Furthermore, according to Vui, HOTS occur when individuals connect new information with existing knowledge stored in their memory, reorganize and develop that information, and apply it to achieve a goal or solve a complex problem.
The primary objective of HOTS is to enhance students' thinking abilities at a higher level, particularly in critical thinking when processing various types of information, creative thinking in solving problems using prior knowledge, and decision-making in complex situations. The concept of HOTS is based on several perspectives, which are summarized in the following table:
This essay argues that HOTS are crucial for preparing students to critically analyze information, solve real-world problems, and innovate in various fields. Despite challenges in implementation, educational strategies such as problem-based learning and interdisciplinary thinking can effectively develop these skills.
Strategies to Develop HOTS in Students
Developing HOTS requires intentional instructional strategies that promote critical, analytical, and creative thinking. One effective approach is the implementation of problem-based learning (PBL), where students engage in real-world problems, encouraging them to analyze situations, evaluate options, and create solutions. Miterianifa et al. (2021) highlight that PBL stimulates critical thinking skills, thereby enhancing HOTS.
Additionally, fostering an environment that encourages questioning and exploration can enhance students' analytical skills. Integrating interdisciplinary thinking, which involves combining knowledge from various disciplines, enables students to view problems from multiple perspectives and develop comprehensive solutions (Fisher, 2001). Utilizing technology, such as educational software and online platforms, can also provide interactive and engaging opportunities for students to develop and apply HOTS.
Challenges in Implementing HOTS
Despite the benefits of HOTS include enhanced critical thinking, problem-solving, and adaptability in an ever-changing world, their integration into education is very difficult. One significant barrier is the traditional emphasis on rote memorization and standardized testing, which often prioritize lower-order thinking skills. The main issue lies in ensuring that students within the PISA-tested age group not only gain access to education but also achieve the literacy levels measured by the PISA. Andreas Schleicher (2019), Director for Education and Skills at OECD, stated,
"After great success in expanding access to education, Indonesia must now focus on quality."
In other words, while increasing access to education has been a success, it must not come at the expense of quality. This presents a critical challenge for Indonesian literacy education. The education budget is still seen as insufficient to both expand access and improve quality at the same time. This issue must be addressed by policymakers at the national level, as well as by teachers who play a crucial role in implementing educational policies.
