Developing Students’ Mathematical Critical Thinking Skills Using Open-Ended Questions and Activities Based on Student Learning Preferences

Abstract

This study has two parts: phase I designed activities to support all students’ learning preferences, and phase II used open-ended questions and activities based on these preferences to develop students’ mathematical critical thinking skills in polynomials at all performance levels (i.e., high-achieving, fair-achieving, and low-achieving students). This research used an embedded mixed-method design. The subjects selected were 28 out of 98 seventh graders at a boys’ junior high school in Bangkok, Thailand, who were chosen by cluster random sampling technique. The instruments, which were validated by five experts, included a questionnaire, lesson plans, exit tickets, interview protocols, and tests of critical thinking skills in polynomials. The content validity was assessed via expert judgment, and reliability was assessed by item analysis. The quality and effectiveness of the instruments were acceptable. The research results showed the following: (1) most students at all performance levels prefer activities in which they can learn from participating in classroom activities, such as games, activities with real-life applications, and activities involving listening instead of reading and writing, and (2) critical thinking skills in high-achieving and fair-achieving students were at the fair level, while those of low-achieving students were poor. Analysis was the highest critical thinking subskill among high-achieving and low-achieving students, while interpretation was the highest subskill in among fair-achieving students. Open-ended questions and activities based on students’ preferences appear to be practical for developing critical thinking skills among students of all achievement levels.

“…Moreover, conceptual understanding, questioning, and investigation are used for the development of curiosity, which is needed for higher-order thinking skills development (Mulyati et al, 2021). Open-ended questions also provide a mindset thought-provoking that is illustrated in the textbook and also supported by the findings of Monrat et al (2022) who are of the view that open-ended questions can be used in developing mathematical critical thinking skills.…”

Problem-based learning utilizing assistive virtual simulation in mobile application to improve students’ critical thinking skills

“…It is also claimed to be the foundation for effectively training 21st-century skills (Preus, 2012). The ways teachers diversify authentic problems into additional preferences (tastes) when students learn (Monrat, Phaksunchai, & Chonchaiya, 2022). Fourth, continue to encourage interaction between students during the learning process.…”

Evaluation of STEM students' critical thinking in terms of cognitive style through problem-based distance learning

“…Authentic learning plays a crucial role in employing effective teaching techniques that foster 21 st -century skills, including critical thinking. Students at every educational level appreciate a diverse range of genuine problems that offer real-world applications within their learning experiences (Monrat, Phaksunchai, & Chonchaiya, 2022).…”

“…As noted by Firdaus, Kailani, Bakar, and Bakry (2015), this approach involves multilateral interactions between learners and teachers, with the instructor facilitating the process. Monrat et al (2022) found that learners exhibited higher motivation to acquire knowledge when immersed in an environment that prioritized active engagement and collaborative interaction, while Syafril, Aini, Pahrudin, and Yaumas (2020) suggested that interactivity in the classroom could help build students' enthusiasm for learning and support their critical thinking abilities.…”
