Critical thinking skills that are claimed to be in the medium and low categories require special attention. Efforts that can be made to overcome these problems are to use an explicit learning model to develop students' critical thinking skills by considering the integration of technology in the learning process. This study aimed to describe the validity, practicality, and effectiveness of blended learning model in promoting critical thinking skill. This study garnered the data regarding the validity from three validators. The practicality of the learning model was based on the applicability of the learning model, students’ responses and challenges faced throughout the teaching and learning process; while the effectiveness of the learning model was based on the increase of the critical thinking skill. The empirical evidence showed that the average score given by the three validators was 3.7 with the percentage of 90% reliability, which falls into a very valid category. The blended learning model enabled the students to develop their critical thinking skill with the average achievement 0.83 for each indicator of critical thinking. This study concluded that the blended learning model was valid, practical, and effective to promote students’ critical thinking skill. The results of this study can be used as an alternative solution to improving students' critical thinking skills that are relevant to technological developments.

The Indonesian National Qualification Framework in higher education requires universities to develop a curriculum that makes students have superior competence with a variety of skills that are in line with the demands of the 21st century, including Critical thinking skills. The main objective of this research is to analyze the practicality of the OR-IPA learning model, which has been developed by design to improve the critical thinking skill of prospective physics teachers on the fundamentals of physics courses. The subject of practical observations was a physics lecturer who used the OR-IPA learning model. The observation sheet of the OR-IPA learning model practicality has been declared valid and reliable by the validators. The data analysis technique uses descriptive qualitative. The results showed that the OR-IPA learning model to improve the critical thinking skill of prospective physics teachers was considered practical (3.69). Lecturers and students can use the OR-IPA learning model without significant obstacles. This research implies that the OR-IPA learning model can be an alternative to improve the critical thinking skill of prospective physics teachers in the fundamentals of physics courses.

The ultimate aim of education is to develop human beings in such a way that they can act beneficial for themselves as well as for the society and can think well and think critically. Development of critical thinking skills is the fundamental aim of education. The present study intended to assess the critical thinking skills among students at higher secondary level in the province of Punjab, Pakistan. The study is quantitative in nature. Population of the study comprises students enrolled in higher secondary level in Punjab. Multistage sampling technique was used to select the sample. A self-developed multiple choice item test was used to assess the critical thinking skills among students. Expert opinion was taken to validate the test and reliability coefficient was 0.86. It was found that majority of students did not perform satisfactory on the critical thinking skill test and scored low on all dimensions of critical thinking skills. The study concluded that curriculum and teaching methodologies along with assessment practices are not worth inculcating critical thinking skills among students. The study recommended that curriculum at higher secondary level might be redesigned and development of critical thinking skill through teaching methodologies might take into consideration by the institutes.
