Abstract

This paper discusses the application of project-based learning (PBL) to improve student’ psychomotor skills and concept understanding, as well as knowing what PBL contribution to the improvement of student’ psychomotor skills in chemistry learning. The study was conducted in three cycles. Each cycle consisted of planning, implementation, observation, and reflection steps. One set of data consists of student’ psychomotor skills assesment, student’ conceptual understanding and questionnaire responses were obtained from the action research. Learning process was performed in the eleventh grade students included 37 students (10 males and 27 females) and 3 collaborators. The successful research was indicated by 85% of students achieve the mastery learning on concept understanding and well on psychomotor aspects. Data collection was performed using documentation method by questionnaire, observations, and tests. Data was analyzed quantitatively and qualitatively. The results show that all aspects of the psychomotor assessed include sets, mechanical response, complex response, adaptation, and origination were in high category. At the end of the lesson, the project assigned to students were evaluated jointly between teachers and students. The project results in the form of a series of distillation apparatus is applied to separate the natural compounds.

Abstract

The purpose of this research is to produce a lecture model of chemical education management based on lesson study as an effort to improve chemistry teacher candidates’ professionalism. This study used a model of ADDIE (Analysis-Design-Implement-Develop-Evaluate). Based on the results of the reflection, lecturer and team can arrange the post-presentation activities (discussing material theoretically) with a variety of management practices in the field. Activities will be carried out by presenting a real problem in the field to find the solution, thus the students’ curiosity about management implementation will be fulfilled. Lecture Model of Chemical Education Management Based on Lesson Study can improve the chemistry teacher candidates’ professionalism, primarily in preparing, presenting and being responsible of their work by learning from their learning experience.

Abstract

Guiding students how to think critically and creatively is a crucial part of the educational process in order to meet the required skills to face the 21st century. In addition, attention to the local culture especially that is closely related to the scientific concepts needs to be strongly emphasized. Due to those two aspects i.e. creative and critical thinking as well as attention to local culture, the ethno-STEM project-based learning for high school students has been implemented and its impact to students’ critical and creative thinking skills has been investigated. This study involved 230 students from seven high schools in Central Java Indonesia. The data collection was carried out through a set of instruments to reveal the students’ critical and creative thinking skills. The instruments were declared as valid based on the experts’ judgment and showed an Alpha Cronbach score of 0.79 prior to use. The results showed that the ethno-STEM project-based learning was able to improve the average critical and creative thinking skills of students in all indicators varying from low to medium categories. The improvement of students' critical thinking skills was observed by the achievement of the N-gain score, i.e. 52 students (22.6%) achieved a high category, 102 students (44.4%) achieved a medium category, and 76 students (33.0%) achieved a low category. Moreover, an increase in the creative thinking skills was also observed, indicated by the N-gain score, i.e. 63 students (27.4%) were at a high category, 109 students (47.4%) were at a medium category, and 58 students (25.2%) were at a low category. In conclusion, the ethno-STEM project-based learning showed a significant effect on the improvement of students' critical and creative thinking skills.

Abstract

Chemical literacy, one of the most important aspects of chemistry teaching and learning, has been paid more attention. However, chemistry learning has not focused much on providing students with learning experiences that could improve chemical literacy. Ethno-STEM approach-integrated inquiry-based learning has been reported as an effective learning model in the chemistry learning. This study aims to analyze the effectiveness of blended inquiry learning with an ethno-STEM approach in improving students’ chemical literacy. This study used a quantitative descriptive approach with a one-shot case study design. Ninety-four first-semester students participating in the General Chemistry course (3 credits) in the teacher education program were involved in the study. During the study, blended inquiry learning with an ethno-STEM approach was applied to the participating students for one semester. Questionnaires, descriptive questions, and interviews were used to collect the research data. A descriptive statistic was used to analyze the data. This study showed that the blended inquiry learning with the ethno-STEM approach was effective to improve the students’ nominal and functional chemical literacy but ineffective to increase conceptual and multidimensional literacy. The students’ prior knowledge in chemistry played an important role in the growth of chemical literacy. A continuing BIL-ethno-STEM in chemistry teaching and learning would allow a significant improvement in the conceptual and multidimensional literacy.
