One effort that can be done to prepare SMA or MA students in entering the world of work is equipping them with the entrepreneurship skills, namely by integrating entrepreneurship into chemistry subjects through teaching materials in the form of modules. This study aims to reveal the level of validity and practicality of a CEP-oriented colloidal system module developed for class XI SMA or MA. The type of research used is Research and Development with 4-D model (define, design, develop, and disseminate). The research instrument used was a questionnaire in the form of validity and practicality sheet. This module was validated by 3 UNP chemistry lectures and 2 chemistry teachers of SMAN 12 Padang. Practicality test were conducted on 2 chemistry teachers and 30 eleventh grade students of SMAN 12 Padang. Data was analyzed by Cohen Kappa Formula. The results of the validity test showed that the module has a very high validity category (kappa = 0.86). Practicality test results by teachers and students showed that the module has very high practicality category (kappa = 0.82 and 0.83). Based on the results of this research, it can be concluded that the module developed was valid, practical.

The Implementation of the curriculum is carried out by practicing process skills that are reflected in learning activities. The process skills applied in the form of 5M activities are known as the scientific approach. This research aims to produce of modul of basic chemical laws based on a scientific approach by applying probing prompting techniques. The research instrument used was a questionnaire of validity and practicality. The module was validated by 5 validators while the practicality test was carried out by 2 chemistry teachers and 20 XI grade students of MIA 3 SMAN 1 Basa Ampek Balai Tapan, Pesisir Selatan. Data from the validity and practicality test results were analyzed using the cohen kappa formula. Based on the results of the study, it was found that the average kappa moment of validity test was 0,89 with a very high validity category and the average kappa moment of teacher practicality was 0,90 and the average kappa moment of students practicality was 0,91 with a very high practicality category. Thus, it was concluded that basic chemical laws module based on a scientific approach by applying probing prompting techniques was valid and practical for high school students.

This research aims to produce a valid chemistry module based conceptual change model Explore, Diagnose, Design, Discuss and Use (ED3U). The steps of this model are align with scientific approach which is an approach used in current curriculum. This model make the student find their own conception and considering their prior conception will resist or they need alternative conception so that they can have scientific conception. In order to optimalize this, the module is presented using three level chemistry representations that are macroscopic, submicroscopic and symbolic. Developments of this module used 4-D model (define, design, develop, disseminate) with check list as a non test instrument for observation in define step. Beside, it also use questioner to determine whether the module is valid or not. The data was analyzed by Kappa Cohen Formula. Based on the three validators who are the chemistry education lecturers and two validators who are lecturers of Design Communication Visual found that the value of k is 0,829 for content validation and 0,69 for graphics validation. It means the module is valid in high category.

This study is a define phase of 4D model used in Research and Development (R&D) that aims to explore initial concept of grade XI students on acid-base topic before studying the material. Instrument used in this study was a two-tiered diagnostic test in the form of multiple-choice questions with choice of reasons that consisted of 16 items. The test was given to 100 grade XI students from various schools in West Sumatra. Students’ answers were processed by grouping them into 3 categories: understand, have misconceptions and do not understand. Data were then analyzed descriptively by calculating the percentage of students' learning difficulties in all of competency achievement indicators that had been compiled. The results showed that students had difficulty in understanding some concepts of acid base such as acid base theory of Arrhenius (75.2%), of Bronsted-Lowry (81.43%), and of Lewis (100%); pH (94.04%); and acid base ionization constant (97.33%). Results of this research are then used as a consideration in the development of acid-base module designed for grade XI Senior High School learning.

This research aimed to analyze students' mental models in chemical equilibrium before and after using guided inquiry-based learning material. The instrument used was a conceptual test which has been developed by Bergquist and Heikkinen. This test was taken before and after formal instruction using the learning material. Responses were obtained from 30 first-year students of Faculty of Mathematics and Natural Science of UNP which taking general chemistry course in 2017/2018 even semester using purposive sampling. Student answers to this test were analyzed descriptively. From this research, student understanding increase after using the learning material. The highest increasing is in equilibrium shifting stoichiometry concept. This gaining correlated to students’ mental model development. The results of this study indicated that in general there has been a development of students’' mental models before and after using this learning material. Although, not all students’ model mental are appropriate to scientific concepts in chemical equilibrium.

Teaching materials used by teachers in acid-base material have not been able to develop students' critical thinking skills. One solution that can be done to develop students' critical thinking skills is using acid-base module’s based on REACT (Relating, Experiencing, Applying, Cooperating, and Transferring). The aim of this research is to produce an acid base module based on REACT and reveal its validity and practicality. The type of research used is Research and Development (R&D) using the 4-D model. The module design has been assessed by seven validators who are Subject Matter Experts (SMEs) consisting of chemistry lecturers from FMIPA UNP and chemistry teachers. While the practicality test was conducted by 3 chemistry teachers and 26 students of class XI MIPA SMAN 1 Padang Panjang. Data analysis techniques in this study used the Content Validity Ratio (CVR) and Cohen's kappa formula. The module design produces three main characteristics, namely: the module is designed in accordance with the prior knowledge of students; the module contains the REACT syntax component; and the module contains aspects of critical thinking skills developed by Ennis. The results of the content validity obtained value of the Content Validity Index (CVI) of 0.90 with a valid category and the results of the construct validity obtained kappa moment of 0.92 with a very high validity category. While the module practicality results according to the teacher and students obtained a kappa moment of 0.86 with a very high practicality category. The conclusion from this study is that the module developed is valid and practical.

This study aims to analyze the quality of chemical literacy instrument on oxidation and reduction reactions material using the Rasch model. The instrument construction is based on four domains of chemical literacy which include aspects of content, context, HOLS, and affective. The instrument assessment rubric is grouped into five levels, namely (1) scientific illiteracy, (2) nominal scientific literacy, (3) functional scientific literacy, (4) conceptual scientific literacy and (5) multi-dimentional scientific literacy. Assessment criteria for chemical literacy instrument carried out by experts include aspects of content, constructs, language and graphics consisting of thirteen sub questions. The score obtained from validation process is a type of multi-rater data which is analyzed by using the Many Facet of Rasch model. The next stage is empirical study of validated and revised instrument was tested on a limited basis to thirty students and analyzed using the Winstep application. Based on the results of the research, chemical literacy instrument is categorized as valid based on the fit test and unidimensionality test.
