Abstract

Not forever what written in theory accepted student correctly. Observing is important to check simulation implementing of inductive model by student of Chemistry Education Program of Chemical Department of FMIPA Unesa after they were studying inductive model theory. Observing was conducted since even semester 2012 / 2013 untill even semester 2015 / 2016. Result of observing show there are some mistake which often happened in simulation implementing of inductive model. First mistake is deem that in open-ended phase teacher is obliged to attend the non example of concept, though the non example of  concept is not obliged to be attended teacher. Second mistake is teacher teach two concept at the same time in a series of inductive model sintak, though ought to a series of inductive model sintak to teach one concept. Third mistake is example of concept and non example of concept in open-ended is always made more simple than convergent phase so that student respon too varying and it is very difficulty by teacher in convergent phase. Fourth mistake is concept which will reach is not well defined so directingstudent to reach concept is difficulty. Fifth mistake is practice problem in application phase less regarding how is student get concept or not representation of conception which have been reached.

Abstract

This study aims to determine the validity of textbook based Reading, Questioning and Answering (RQA) in process assessment and learning outcomes course at chemistry department Unesa. The research method uses research and development (R & D).The results showed that the textbook based RQA was feasible in term of construct validity with very valid category, content validity with very valid category, language and readability with valid category, and in accordance with the RQA strategy with a valid category.From this research, it can be concluded that the texbook suitable for use in process assessment and learning outcomes course.

Abstract

Learning materials have been developed which then conducted the study and validation to the expert lecturers and then tested to the students to find out the validity of the feasibility of learning materials in the field of Industrial Chemistry as one of the supporting subjects of Ecopreneurship in Chemistry Department. From the data obtained can be concluded that learning materials in the form of Lesson Plan, Worksheet, and Instrument Rating get very good criteria. These criteria are obtained based on theoretical feasibility and empirical feasibility. Based on these results, learning tools developed can be used as learning tools for Industrial Chemistry courses to support ecopreneurship.

Abstract

Abstract. This research to describe implementation of Problem Based Learning models, activities students, and critical thinking skills (CTS) in learning using PBL models on acid-base material. The design used is One Group Pretest Posttest Design with 32 subjects.  This study resulted is: (1) implementation of learning using PBL model  get the results of the average value sequentially at meetings one and two of 3.60 and 3.76, with very good criteria (2) Students perform relevant activities  meaning of students have practiced CTS. The relevant activities of students in sequence at meetings one and two of 98.75% and 97.7%. (3) CTS learners experienced an increase, overall the pretest and posttest scores of students received a percentage of 90.63% students in high category and 9.38% in medium category. The percentage of component of interpretation, inference, and analysis in high category are as follows 78.13%; 81.25%; 90.63%, and the medium category 21.88%; 18.75%; 9.28%.
