This study aims to determine the effect of applying problem-based learning models on critical thinking skills and scientific attitudes of pre-service chemistry teachers in Basic Chemistry 1. This quasi-experimental research uses pre-test and post-test through an unequal control group design. This research has been carried out for 3 months from September-November in 2021 on pre-service chemistry teachers. The data were analyzed using Hotelling's T2 test and the Rasch model. Empirical evidence shows that based on Hotelling's T2 test results obtained a significance value of 0.001 < (0.05) with a partial eta squared value of 0.28 which means Ha is accepted. So, it can be concluded that there is a contribution of problem-based learning models on critical thinking skills and scientific attitudes of students with the contribution of 28%. Another finding also shows that based on the results of the Rasch model test, it shows that in the experimental class the indicators of critical thinking skills and scientific attitudes are mostly possessed the ability to synthesize attitudes towards scientific investigations. The indicators of critical thinking skills and scientific attitudes are least possessed the ability to analyze and chemistry learning experiences. The conclusions of this study include there is a significant effect of the application of the PBL model on students' critical thinking skills and scientific attitudes with a model contribution of 28%, as well as critical thinking skills and scientific attitudes that most students have in the experimental class are analytical skills and attitudes towards scientific investigations.

This study aimed to analyze the effect of problem-based learning on metacognitive abilities in the conjecturing process of junior high school students. To reach this purpose, a mixed-methods design, which is a combination of quantitative and qualitative methods, was used. The quantitative method was used to analyze the metacognitive abilities of the students’ conjecturing process, while the qualitative method was used to explore observation and interview data. The subjects of this study consisted of 60 eighth-grade students. Two learning models were compared, namely the problem-based learning model and the conventional learning model. The metacognitive abilities of students’ conjecturing process were measured by a pattern generalization problem-solving test. After collecting the data and analyzing them through the independent-samples t-test, it was revealed that the PBL had a significant effect on the metacognitive abilities of students’ conjecturing process in solving pattern generalization problems. Finally, based on the results, some conclusions and implications were suggested.

Purpose Furthermore, the purpose of this study is to compare the student engagement and the learning outcomes in offline and online PBL in the aforementioned course. The COVID-19 pandemic has caused disruption in various sectors, including education. Since it was first announced in mid-March 2020 in Indonesia, teaching and learning activities have been carried out online. In this study, a comparison of the offline (Spring 2019, prior to the pandemic) and online (Spring 2021, during the pandemic) problem-based learning (PBL) method in the sustainable chemical industry course is investigated. Design/methodology/approach A quantitative analysis was conducted by measuring the students’ engagement, course-learning outcomes (CLOs) and student learning outcomes (SLOs). Difference tests of engagement score, CLOs and SLOs were investigated by using the t-test or Mann–Whitney U-test. Furthermore, the perceived students’ stressors were measured. Findings It is found that the students’ engagement in offline and online PBL gives similar scores with no significant difference. This is possible because of the PBL structure that demands students to be actively engaged in gaining knowledge, collaboratively working in teams and interacting with other students and lecturers. Although similarly engaged, the CLOs and SLOs of online PBL are significantly lower than offline PBL, except for SLO related to oral and written communication skills and affective aspect. The decrease in CLOs and SLOs could be influenced by students’ academic, psychological and health-related stressors during the COVID-19 pandemic time. Originality/value This study provides a recommendation to apply online PBL during the COVID-19 pandemic time and beyond, although some efforts to improve CLOs and SLOs are needed.

Background: Small group work embraces independent study and interactive learning, which enhance knowledge acquisition and skills. Self-directed learning (SDL) and problem-solving (PS) are essential skills in the development of the nursing profession. During the coronavirus pandemic, virtual learning was indispensable. However, little is known about how students develop SDL and PS abilities through online learning through group work. Objective: To evaluate the effects of the online intervention on SDL and PS abilities through interactive group work. Methods: A randomised waitlist-control trial was carried out. A structured intervention using problem-based learning (PBL) as a guideline was used to direct student learning in small group work. Assessments were scheduled at Time 0 (baseline), Time 1 (8th week), Time 2 (16th week), and Time 3 (28th week). Results: The mean student age was 21.45 (SD = 0.86). About 78% of students were female. There was no significant difference in demographic characteristics and analysis at the baseline. Students in the intervention group reported greater improvement in the SDLRS and PSI at the 8th week, whereas those in the waitlist control group reported greater improvement in the SDLRS and PSI at the 16th week. Sustained effects in the SDLRS and PSI were observed in both the intervention and waitlist control groups at the 16th and 28th weeks, respectively. A repeated-measure analysis was performed to compare the SDLRS and PSI in different periods and revealed statistically significant results (p < 0.001) in all subscales of SDLRS and PSI in the four study periods. Conclusions: The guidelines appear to be an effective treatment for SDL and PS ability enhancement with sustainable effects through interactive group work. The guidelines with explicit instructions and learning objectives provide directions and guidance to students to learn more effectively. The educator plays a vital role in facilitating the students’ SDL and PS ability improvement.

Background: The Covid-19 pandemic has influenced health education in many countries, including nursing education that moved to online learning.  It affects the tutor's performance and students' critical thinking skills, especially in online PBL tutorials. Tutor and nursing students have to re-adapt to a new online meeting atmosphere that previously had face-to-face meetings. There was no previous investigation into the effect of online PBL on tutor performance and nursing students’ critical thinking skills in UMY.Purpose: This study aims to determine students’ perceptions of tutor performance in online problem-based learning tutorials and the critical thinking skills of nursing students in UMY.Methods: This research is a cross-sectional quantitative study. The sample included 91 second-year nursing students, using the total sampling technique. The researchers used two questionnaires with closed questions about the tutor's performance in PBL tutorials and the critical thinking skills. Data were analyzed by univariate analysis. Result: The majority of respondents were female (83.5%) and 19-20 years old (91.2%). The study results showed that the tutor's performance on the online PBL tutorial was in the good category (95.6%), while the critical thinking ability was in the poor category (54.9%).Conclusion: This study showed that students still needed to adjust and adapt maximally to online problem-based learning tutorials and needed support and motivation to improve the quality of learning.

Recommendations for enhancing scientific literacy, inclusivity, and the ecosystem for innovation call for transitioning from teacher-centered to learner-centered science classrooms, particularly at the introductory undergraduate level. Yet, little is documented about the challenges that undergraduates perceive in such classrooms and on students' ways of navigating them. Via mixed methods, we studied undergraduates' lived experience in one form of learner-centered teaching, hybrid project-/problem-based learning (PBL), in introductory organismal biology at a baccalaureate institution. Prominent in qualitative analyses of student interviews and written reflections were undergraduates' initial expectation of and longing for an emphasis on facts and transmission of them. The prominence diminished from semester's middle to end, as students came to value developing ideas, solving problems collaboratively, and engaging in deep ways of learning. Collaboration and personal resources such as belief in self emerged as supports for these shifts. Quantitative analyses corroborated that PBL students transformed as learners, moving toward informed views on nature of science, advancing in multi-variable causal reasoning, and more frequently adopting deep approaches for learning than did students in lecture-based sections. The qualitative and quantitative findings portray the PBL classroom as an intercultural experience in which culture shock yields over time to acceptance in a way supported by students' internal resources and peer collaboration. The findings have value to those seeking to implement PBL and other complex-learning approaches in a manner responsive to the lived experience of the learner.
