Educational transformation in the 21st century demands in-depth knowledge and understanding in order to promote the development of higher-order thinking skills (HOTS). However, the most commonly reported problem with respect to developing a knowledge of chemistry is poor mastery of basic concepts. Chemistry laboratory educational activities are shown to be less effective in developing an optimum conceptual understanding and HOTS among students. One factor is a lack of effective assessment and evaluation tools. Therefore, the primary focus of this study is to explore concept maps as an assessment tool in order to move students' thinking skills to a higher level during laboratory learning activities. An embedded mixed method design is used in this study, which has also employed a pre-experimental research design. This design triangulates quantitative and qualitative data, which are combined to strengthen the findings. A low-directed concept mapping technique, convergence scoring method, and pre-post laboratory concept map were used in this study. An electrolysis HOTS test was used as the research instrument in order to measure the level of student achievement with respect to high-level questions. In addition, the thought process that is involved when students construct concept maps has been explored and studied in detail by utilising a think-aloud protocol. Results showed a positive development towards understanding and higher level thinking skills in students with respect to electrolysis concepts learned through chemistry laboratory activities. An investigation of the students' thinking processes showed that high-achieving students were more capable of giving a content-based explanation of electrolysis and engaged in monitoring activities more often while building a concept map. Nonetheless, all categories of students managed to show a positive increase in the activities of explanation and monitoring during the construction of concept maps after they were exposed to the assessment tool in the laboratory learning activities. In conclusion, the assessment activity using concept maps in laboratory learning activities has a positive impact on students' understanding and stimulates students to increase their HOTS.

Design and evaluation processes to provide an empirical basis for producing instructional and non-instructional products, tools, and new or improved development models. This method uses various methods, including qualitative and quantitative techniques, and thoroughly examines the literature. The design and development of this chemistry module using design thinking to empower students' innovation competencies are described in this article. The main challenge for the teaching implementation process that is capable of mastering the skills of generating new ideas and solving problems in the real world is preparing teaching materials, consuming time, and putting pressure on the teacher. Teachers need more support resources to translate the expected teaching practices. This effort aims to generate a new perspective in education, especially chemistry education, in developing student innovation competence in secondary schools in Malaysia. Therefore, this study aims to discuss the design and development research (DDR) approach used to develop a design thinking chemistry module using a DDR approach. The researcher will go through three study phases and use several different research approaches in each phase. In the first phase, the researcher investigated the teachers' needs in their pedagogy used in teaching and students' innovation competencies. The second phase is the design and development phase, involving the consensus of twelve experts in various fields, such as chemistry/science, technology, engineering, and mathematics (STEM), curriculum development, module construction experts, and research and innovation planning experts. Consequently, the final phase is implementation and evaluation, focusing on determining the module's effectiveness in teaching and learning. Expert consensus is the primary input in developing modules in Malaysian chemistry education. Malaysian education needs to bring a different educational paradigm and teaching strategy, which includes the impact of teacher pedagogy through design thinking in the future. The conclusion of this article proposes a conceptual framework for the research to contribute to the advancement of design thinking and chemistry education.

Chemistry is a scientific discipline that is often considered difficult because students struggle to solve contextual and open-ended problems, mainly due to a poor understanding of scientific concepts related to the problem. To fully grasp the concepts in chemistry, students must develop the ability to solve real-life problems. Problem-solving skills are applied in many aspects of life, making them crucial for the 21st century. Problem-based learning (PBL) is an effective method for improving students’ problem-solving skills. This study aims to outline how the PBL approach enhances students’ problem-solving skills, specifically in the context of chemistry education. The sixteen research articles reviewed in this paper were collected from well-known databases such as ERIC, SCOPUS, and Google Scholar. Systematic literature review (SLR) is the method used in this review. This review provides evidence that PBL can enhance problem-solving skills in chemistry education. All research articles have shown that PBL has a significantly positive effect on the problem-solving skills of students. Seven out of sixteen articles have provided insights into the design and framework of PBL implementation. The researcher recommends conducting more studies in all areas of chemistry to provide clear guidance on incorporating PBL. The researcher also recommends using mobile technologies to integrate PBL in a stimulating manner, such as by developing a mobile application to aid in the instructional process. Proper insights into the effectiveness of implementing PBL to enhance problem-solving skills in chemistry, as well as the integration of PBL into the instructional process, are necessary. This will aid teachers and lecturers in planning their lessons, which is why this systematic review is needed.

This study aimed to identify the specifications for developing a problem-based learning e-module for chemical equilibria to increase students’ higher-order thinking skills (HOTS). A qualitative approach with a semi-structured interview involving eight participants from form six teachers in Penang was utilized. The interview results were analyzed using NVivo 12 software by dividing the transcripts into several codes based on a thematic analysis approach. Four broad themes emerged from the need analysis interviews: i) the importance of chemical equilibria; ii) problems in teaching and learning chemical equilibria; iii) teaching strategy; iv) desired improvement. The findings of this study showed that the topic of chemical equilibria in form six syllabus is an important topic for students to master. Still, it is the most challenging concept for both students and teachers. Findings of the interviews also found that teachers need an e-module integrated with problem-based learning due to the lack of teaching resources, the content of the syllabus, and the lack of students’ thinking skills. Besides, teachers suggest variegating the content, strategies, and technology to develop the modules. These findings indicate that teachers are still unsatisfied with the existing teaching materials and strategies and, therefore require an e-module to meet their needs. All themes and codes of the findings are summarized using schematic diagrams. The results of this study are essential in designing and developing the e-module integrated with problem-based learning for the topic of chemical equilibria, which can be implemented and positively increase the HOTS level among form six students.
