Chemistry textbooks' questions are important in improving students' thinking skills. Various types of questions are developed, but the effectiveness of these questions in supporting student success is something that is not expressed enough. This study aims to determine aspects of critical thinking skills developed in questions in the Chemistry High School textbook. The research method used is a descriptive method and multistage sampling technique. There are six books analyzed. The research instrument used was in the form of observation sheets classifying questions based on indicators of critical thinking skills. The results showed that the questions developed in Chemistry textbooks were analyzed based on critical thinking skills, including aspects of making simple explanations with a percentage of 28.8%, building basic skills of 20.3%, concluding at 45.8%, giving further explanations of 3.4%, and set strategy and tactics of 1.7%. The questions developed are dominated by concluding questions. Thus, it can be concluded that the questions in the Chemistry High School textbook have not been developed evenly on the five aspects of critical thinking.

This study aims to analyze the exit survey developed at UIN Syarif Hidayatullah Jakarta as part of the monitoring and evaluation efforts obtained from graduation students. Monitoring and evaluation conducted in this survey exit, thesis supervision, and academic advisor. Analysis was done by considering four aspects of content, administration, analysis, and integration strategy. This research was conducted at UIN Syarif Hidayatullah Jakarta. The research was conducted from March to August 2016 at UIN Syarif Hidayatullah with respondents of the graduates from various faculties and study programs. The result of this research was: 1) Based on the content it can be seen that items in service survey, thesis supervision and academic advisor have medium reliability. This provides an opportunity for institutions to review the items that have not been done thoroughly and comprehensively, 2) Based on this online administration has several advantages such as the effectiveness of time, human resources and budget. Nevertheless, the potential weaknesses of the online system also need to be considered among them is the stability of the network and the system itself, 3) To provide a reading of data analysis results that are beneficial for service improvement, the exit survey data is analyzed using Rasch Model. It provides detailed analysis of items and respondents and mentors / advisers in detail, 4) integration strategies have great potential to have a significant impact on quality development efforts. Nevertheless, in this study the integration strategy cannot be done considering the need for further steps such as the publication of results to the leadership, the leadership commitment to the recommendations, as well as monitoring and evaluation of leadership commitments within the agreed timeframe.

This study aimed to develop and validate the Three-Tier Chemical Equilibrium Multiple-Choice Test–HOTS (TTCEMCT–HOTS) instrument. The method employed in this study was Research and Development (RD) based on Brookhart’s (2010) indicators of higher-order thinking skills. The development procedure began with a preliminary study, followed by product draft planning and product development. These stages were succeeded by an empirical analysis of the TTCEMCT–HOTS to determine the test instrument’s validity, reliability, difficulty level, and discriminating power. The TTCEMCT–HOTS instrument was implemented with Class XI students of SMAN 4 in South Tangerang City. The results of the study were as follows: (1) the developed TTCEMCT–HOTS instrument met the criteria of 32 valid questions, with a reliability coefficient of 0.82 in the “very high” category, a “moderate” difficulty level, and “good” discriminating power; (2) 46.42% of students could solve HOTS questions, while 53.58% could not; (3) the TTCEMCT–HOTS instrument received a positive response from 80.6% of participants, placing it in the “good” category. This study is expected to provide an alternative method for measuring students' higher-order thinking skills using a three-tier test instrument integrated with HOTS indicators.

The aims of this study are to analyze the interpersonal relationships between chemistry teachers and their students, to investigate chemistry teacher interpersonal behaviour using Model for Interpersonal Teacher Behaviour (MITB), and to identify the interpersonal behaviour profile of chemistry teacher according to student’s perception. The data were collected from 472 eleventh grade students of science class in 5 Public Senior High School and 5 Private Senior High School in South Tangerang Municipality who were randomly sampled using teacher-student interpersonal relationships questionnaire adapted from Questionnaire on Teacher Interaction (QTI). Data were analyzed using Rasch model in Winsteps version 3.73. Results showed that in general, it was indicated that the interpersonal relationships of chemistry teachers and their students are categorized as relatively good. The teachers were considered to have adequately dominant and very cooperative behaviour with students in classroom. Meanwhile, in terms of interpersonal behaviour scale, students perceived their teachers as having higher rate on leadership, helping/friendly, and understanding behaviour than the hostility behaviour. Then, according to interpersonal behaviour profile, it showed that chemistry teachers in South Tangerang Municipality were identified as authoritative.
