The present study aims to examine the implementation of a stepwise inquiry approach to improving communication skills and scientific attitudes. Stepwise inquiry comprises structured inquiry, guided inquiry, and open inquiry. The variables measured were communication skills and scientific attitudes. The construct used to measure communication skills involved written, verbal, and social communication skills, along with scientific attitude indicators including curiosity, openness of mind, objectivity, honesty in reporting results, responsibility, and mutual respect. The design of the study employed a posttest-only control group design with an experimental class of 20 students and a control class of 21 students. The effect of stepwise inquiry implementation was analyzed using MANOVA. The results reveal that the classes implementing stepwise inquiry had higher scores for communication skills and scientific attitudes than those undertaking expository approaches. The implementation of stepwise inquiry significantly affects the scores of scientific communication and attitude skills based on MANOVA analysis. The involvement of students independently in the investigation process increases their ability to construct knowledge and build arguments, in addition to increasing their motivation for learning. This established motivation enables the formation of positive attitudes, such as scientific attitudes, in the students.

Biochemistry subject had problem in learning and teaching, especially in laboratory work. We explored laboratory learning implementation in Biochemistry subject. Participants of this research were 195 students who took biochemistry subject and 4 lecturers of biochemistry in three universities in Indonesia. We obtained data using questionnaires and free response data. Questionnaires students' analysis showed there were two statements that very positive perception, five statements that obtained positive perception and ten statements with negative perception. Biochemistry lecturers questionnaire analysis showed seven statements that had been implemented and nine statements had not been implemented. Free response data indicated that effective learning in the laboratory was affected by several aspects which were pre-lab stage that could increase the students' motivation, lab-work stage with complete tools and materials as well as better ability of the assistants, and post-lab stage that could give feedback to the experiments' report and chances for the students to present their investigation results.

We have developed an OD3R method that can be applied on Biochemistry learning. This OD3R consists of 5 phases: orientation, decision, do, discuss, and reflect to connect lessons in the class with practice in the laboratory. Implementation of OD3R method was done in 2 universities in Yogyakarta to increase critical thinking skill and practical skill of the students. The critical thinking skills were assessed using modified Hoyo rubric according to student's ability in writing laboratory work report. Practical skill was assessed using a rubric with 6 practical skill categories: procedural skill, manipulative skill, observation skill, drawing skill, interpretation skill, and presentation skill. Implementation result shows that OD3R method can increase critical thinking skill and practical skill of the students. OD3R method is a learning method that is centered on the students and can be recommended to train thinking skill and practical skill of students in University. © 2017 by The International Union of Biochemistry and Molecular Biology, 46(2):107-113, 2018.

The implementation of KKNI curriculum in Indonesia requires meaningful learning-so does the biochemistry learning. In the mean time, biochemistry learning is constrained by the fact that its implementation and assessment have yet to be integrated with classroom learning and laboratory works. The Orientation/Decision/Do/Discuss/Reflect (OD3R) method seeks to integrate the elements and makes biochemistry learning meaningful. The implementation of the OD3R method in 4 universities in Indonesia (N = 216) shows that this method can help students to integrate information obtained from lectures by writing good laboratory reports, improve practical skills, and improving students' scientific attitudes. Each stage in the OD3R method meets cognitive, affective, and psychomotor domains in the biochemistry learning. More details on the OD3R method and its assessment are described in this paper.Keywords: biochemistry learning, laboratory work report, practical skills, scientific attitudes, meaningful learning INTRODUCTIONSince 2012, curriculum of higher education in Indonesia has changed by using the Indonesian National Qualification Framework (KKNI). This change is based on the concept of four education pillars, namely 'learning to know', 'learning to do', 'learning to be', and 'learning to live together' that are initiated by the United Nations Educational, Scientific and Cultural Organization (UNESCO). With KKNI, learning 18Meaningful Biochemistry Learning Using the Orientation … International Journal of Instruction, July 2018 • Vol.11, No.3 outcomes are expected to not only consist of knowledge but also attitudes and skills. This also happens to chemistry curriculum in higher education.Biochemistry is a course that must be taken by undergraduate students of chemistry and chemistry education programs. However, there are problems in the learning process. Students say that biochemistry is a difficult course, in which concepts to study are too many. Moreover, the concepts are irrelevant to students' life and careers (Anwar et al., 2013;Varghese et al., 2012; Afsar & Han, 2014;Anderson & Grayson, 1994;Fulton et al., 2012). In addition, there is no method that is capable of integrating study and laboratory work during learning implementation and assessment (Anwar et al., 2017).Laboratory work in biochemistry learning does not only serve to prove theories but also to stimulate and to improve skills for lifelong learning (Ottander & Greelson, 2006;Hofstein et al., 2008;Kelly & Finlayson, 2007). Until now, traditional methods remain the only choice for implementation of laboratory work. Students only duplicate methods, record investigation results, and note down the results on reports to which teaching assistants and lecturers never give feedback. To date, there is no method that integrates classroom learning and laboratory works in biochemistry learning implementation and assessment in Indonesia.Previous research has been developed to improve the implementation of laboratory works.

The coronavirus disease 2019 (COVID‐19) pandemic is a case that can be used as a biochemistry learning resource in relation to the topic of viruses. Learning to use cases will be effective if students are assigned to produce reports, articles, or other scientific papers. Self‐assessment can be used to assess the competencies that have been learnt in the writing process. This study aims to analyze the scientific papers and self‐assessment of students using the COVID‐19 pandemic case. It includes qualitative research with scientific paper and self‐assessment questionnaire analyses. The research sample was chemistry education study program students ( N = 57) following biochemistry course, out of a population of 87 students. The results show that the students have a good understanding of explaining COVID‐19. Self‐assessment analysis shows that 80% of the students responded positively to eight statements; those who gave positive responses to each questionnaire statement were able to produce scientific papers. Good self‐assessment is in line with the ability of students to compile good scientific papers.

Pembelajaran saat ini mengutamakan terwujudnya karakter yang baik pada peserta didik. Penggunaan etnosains sebagai pendekatan diharapkan mampu mewujudkan hal tersebut. Namun, hingga saat ini pendekatan etnosains belum banyak dilakukan dalam pembelajaran kimia. Sebagai upaya mengembangkan model pembelajaran kimia berbasis etnosains perlu dilakukan penelitian terkait tanggapan guru kimia selaku praktisi terhadap pendekatan etnosains dalam pembentukan karakter siswa melalui pembelajaran kimia. Penelitian ini merupakan penelitian kualitatif dengan melibatkan 113 guru kimia sebagai responden. Alat pengumpul data yang digunakan adalah kuesioner yang berisi pernyataa terkait pembelajaran kimia dan pendekatan etnosains. Hasil penelitian menemukan bahwa sebagian besar guru belum menggunakan pendekatan etnosains dalam pelaksanaan pembelajaran kimia baik pembelajaran di kelas maupun di laboratorium. Pembelajaran kimia dengan pendekatan etnosains perlu dikembangkan untuk dapat membangun karakter siswa. Perlu dikembangkan model pembelajaran dan modul pembelajaran dengan memasukkan unsur budaya dan sesuai dengan kurikulum 2013 agar siswa lebih memahami konsep kimia dan mengenal budaya sekitar sehingga mengubah persepsi siswa bahwa kimia dekat dengan kehidupan sehari-hari.
