Higher and Lower-Order Thinking Skills: The Case of Chemistry Revisited

Abstract

This work analyses students’ failure in the 2019 Nationwide Chemistry Examination in Greece, which concerns secondary education graduates, competing for admission to higher education Greek institutions. The distinction of thinking skills into higher and lower order (HOTS and LOTS) is used as a theoretical tool for this analysis. The examination included several questions that contained HOTS elements that had been unusual in previous examinations. This led to a decrease in overall student performance but better discrimination between outstanding and good students. Based on two samples of examination papers, corresponding to very similar subsets of the student population, the 2018 and 2019 examinations are compared, and the individual 2019 questions are evaluated. It was found that section B of the 2019 examination paper (which included contexts unfamiliar to the students, and for which, a large effect size between 2018 and 2019 was calculated) may have caused the large drop. An important link is established between the 2019 low performance and the HOTS and LOTS features of the questions, and the role or non-role of algorithmic calculations is examined. In addition, the critical opinions of chemistry teachers are provided, with a consensus emerging in favour of connecting chemistry with everyday life. Keywords: chemistry examinations, higher-order cognitive skills, higher-order thinking skills, student assessment, twelfth-grade chemistry.

Effect of Scaffolding Strategies on Higher-Order Thinking Skills in Science Classroom

“…The research results support Arase et al (2016) and Vejian et al (2016), who suggested that creative school climate would cultivate creative behaviour and interactive work among school stakeholders including teachers and learners. The research results prove the claim by Tsaparlis (2020), which states that several education processes are required to enhance science students' HOTs.…”

Using Bloom’s taxonomy to evaluate the cognitive levels of Primary Leaving English Exam questions in Rwandan schools

“…In general, there is a tendency of giving a paramount importance and special attention to the knowledge and remembering domains (Tikhonova & Kudinova, 2015 ; Tsaparlis, 2020 ). According to Krathwohl ( 2002 ), knowledge and comprehension are frequently considered the foundation to all the other education objectives (Chmielewska & Gilanyi, 2018 ).…”

“…The organization for Economic Co-operation and Development (OECD) highlighted one of the elements behind Indonesia's lagging as a focus on Lower Order Thinking Skills (LOTS) in the learning process. With this style of teaching and learning, there is no systematic strategy for strengthening minds in the 21st century (Barut & Wijaya, 2021;Qasrawi & Beniabdelrahman, 2020;Tsaparlis, 2020). Teaching and learning activities which are increasingly dominated by explanations from teachers make learning boring, one-way, and less able to create ways that educate and empower students' learning abilities to discuss, conduct case surgery, solve the problem, experiment, observe, etc.…”
