Level: Undergraduate/adult Setting: Classroom Activity Type: Learning Cycle Discipline: Chemistry Course: Modified GOB chemistry keywords: buffer, buffer capacity, weak acid, conjugate base Abstract The GOB chemistry course is part of a biomedical workforce development program for adults with a wide range of backgrounds. A significant number of students have not studied chemistry before, or have a very basic middle school level. In the laboratory, students will learn to make biological buffer solutions, adjust the pH of a buffer solution by addition of acid or base, and utilize the concept of buffer capacity. This POGIL activity provides the students with a conceptual understanding of what is happening to the buffer upon addition of acid or base and why the buffer solution shows a smaller change in pH than a solution without any buffer. The particle diagrams are adapted from a tutorial created by Chem Collective: http://chemcollective.org/activities/tutorials/buffers/buffers1

One of the essential skills students should possess in the 2013 Curriculum is critical thinking. However, students' critical thinking skills in buffer solution material are considered low. Therefore, this study aims to identify the different critical thinking skills between students who attend a process-oriented guided oriented learning (POGIL) with and without science, environmental, technology, and society (SETS) approach on buffer solution material. This research uses quasi-experimental with a posttest-only control group design. The research results reveal that: (1) both POGIL learning models with and without the SETS approach are classified to be successfully carried out; (2) different critical thinking skills are found in students who learn using the POGIL learning model with and without the SETS approach on buffer solution material. The POGIL learning model with the SETS approach carries better students' critical skills results than the one with no SETS approach on the buffer solution material.

This research aims to describe the effectiveness of the POGIL model to increase learning motivation and mastery of the concept of buffer solutions students. The research method used is quasi-experimentation with pretest-postest control group design. Sampling is done by random sampling cluster technique and obtained class XI IPA 3 as an experimental class and class XI IPA 4 as a control class. The effectiveness of the POGIL model was analyzed using the n-Gain two-average difference test to learning motivation and mastery of concepts learners' between experimental class and control class. The results of the analysis of the study data showed that the average value of n-Gain motivation learning of learners in the experimental class was greater than the control class, as well as the average grade of n-Gain mastery of concept of the experimental class was greater than the control class. The results of the influence test analysis also showed that increased learning motivation and mastery of the concept of buffer solution students were influenced by the POGIL model. It can be understood that learning with the POGIL model is effective to increase learning motivation and mastery of the concept of buffer solution students.
