Test Instrument

The main analysis in developing assessment instruments is reliability and validity. A validity test is carried out to determine the appropriateness instrument that will be developed, both construction validity and content validity. The reliability test is to determine the level of consistency of the instrument that has been developed. This research was conducted to develop the HOTS ability to test items for high school students. The grid test instruments are arranged based on competence and HOTS indicators, which are then used to arrange items. The test instrument consisted of ten question items relating to the HOTS Thermodynamic Law problem, which included: 1) analyzing the magnitude of engine efficiency, work, heat, and internal energy changes, 2) evaluating Carnot's efficiency, and 3) creating a heat engine. The assessment of the instrument HOTS test obtained Aiken's V score in the range of 0.83 to 0.94, which is in the valid criteria. The validated instrument was piloted in 141 science grade XI student in High School 2 Batang, at Batang Regency, Central Java. The level difficulty of the Polytomous data was analyzed using the QUEST program for classical analysis and PARSCALE 4 for modern analytical theory based on the Partial Credit Model (PCM). The results of data analysis of the experimental items show that of the ten-question items, all are compatible with PCM. The reliability of the test instrument is 0.84, and the item difficulty level is in the range of 0.83 to 1.22. Information functions and Standard Error Measurement (SEM) indicate that test questions developed reliably to measure HOTS students' ability with an average category in -1.9 <θ <+1.7 logit scale with SEM ± 0.5.

Is Development

The lack of laboratory equipment and malfunctioning laboratories in schools makes teachers reluctant to carry out practical activities, especially on the topic of environmental change. This study aims to produce an effective practicum activities in accordance with the demands of the curriculum in the elementary school of high school students on the material of global warming. The method if used in this research is descriptive research method. To test the effectiveness of practicum activities developed used a class experiment in class X in a high school by using pretest and posttest. This research uses Thiagarajan et al. (1974) development model that is development model (4-D) (Four-D models). This development model consists of four stages, namely definie, design, develop, without disseminate. The test instrument is a matter of multiple choice with 15 items that have been validated by the expert. The results of the validation show that the greenhouse effect modeling activity, developed in this research is feasible and effective. The effectiveness criteria of the practicum activity refers to the achievement of the average value of the students that exceeds the minimum score (75).

This study aims to determine whether there is an influence on the implementation of PBL through a scientific approach that provides a media card for high school students' chemistry learning outcomes. To achieve this goal, quasi-experimental research was conducted using two classes, namely the experimental class and the control class. Data obtained using a validated test instrument in the form of pretest and posttest. The results showed that (1). There was an increase in chemistry learning outcomes from the average pretest 27.2 to 63.95 and 72.5 in the two classes of experiment I and experiment II, respectively. (2). Student learning outcomes that are taught with the Problem Based Learning model and the scientific approach provides higher paired cards than using textbook as a media.

This study aims to determine the development of mathematical representation skills of junior high school students (SMP) based on mathematical exam results data in 2014-2016. The research data was obtained from responses of students' answers consisting of 1,535 students in 2014 and 2,000 students in 2015 and 2016 classified based on indicators of mathematical representation ability. In addition, the classification of student response data is also by gender and type of school. This research is a descriptive research using tables and graphs to describe data analysis of the development of the ability of mathematical representation in each year. The results show that the average percentage of mathematical representation ability of junior high school students in creating and using representations to organize, record and communicate mathematical ideas decrease every year. In indicators uses representation to model and interpret the physical, social, and mathematical phenomena increase in 2014 to 2015 but decrease in 2016. In general, the average percentage of mathematical representation ability of male students is higher than female.

This research is aimed at describing (1) the characteristics of items about a diagnostic test of circle material in mathematics, (2) how significant the percentage of students' types of errors in answering the questions, and (3) the diagnosis of students' difficulties in answering the questions based on DINA model. This research is quantitative descriptive research involving eighth graders of junior high school in East Lombok regency as the population. The sample was chosen by a proportionate random sampling technique, consisting of 105 students for preliminary field testing and 416 students for main field testing. The instrument of this study was a diagnostic test using a four-option multiple-choice format. Data on students' responses were analyzed using the R program with CDM (Cognitive Diagnostic Model) DINA model, which requires underlying attributes for each item. The results show that: (1) the diagnostic test instrument had met the qualitative and quantitative content validity; (2) the percentage of students' answers retrieved from the conceptual error is 18.47%, 9.99% is interpretation error, the procedural error is 7.80%, and counting error is 14.57%; (3) based on the results of the analysis with DINA model, students' error in answering the questions of the circle material in mathematics are dominantly caused by students' lack of mastery on solving problems associated to the circumference of a circle, that is, (A28) the ability to calculate the length of a path, and (A29) the ability to calculate many rounds on wheels.
