Opportunities and challenges for deep constraint languages
Authors: Atkinson C , Gerbig R , Kuehne Thomas
Published: November 2020

Structural models are often augmented with additional well-formedness constraints to rule out unwanted configurations of instances. These constraints are usually written in dedicated constraint languages specifically tailored to the conceptual framework of the host modeling language, the most well-known example being the OCL constraint language for the UML. Many multi-level modeling languages, however, have no such associated constraint language. Simply adopting the OCL for such multi-level languages is not a complete strategy, though, as the OCL was designed to support the UML's two-level class/instance dichotomy, i.e., it can only define constraints which restrict the properties of the immediate instances of classes, but not beyond. The OCL would consequently not be able to support the definition of deep constraints that target remote or even multiple classification levels. In fact, no existing constraint language can address the full range of concerns that may occur in deep modeling using the Orthogonal Classification Architecture (OCA) as an infrastructure. In this paper we consider what these concerns might be and discuss the syntactical and pragmatic issues involved in providing full support for them in deep modeling environments.

Published: November 2020

In mathematics learning a person often solves problems. In solving mathematical problems, a person needs a thought process with the thought process that an individual can come up with an idea to solve mathematical problems correctly. Stages of thinking take place individually and have a relationship with the social interactions carried out. The interaction will produce behavior. One factor that influences behavior is emotion. Therefore, the behavior of every individual must be related to good emotional control so that it can produce good behavior as well.Good emotional control requires preparedness and thought so that the behavior carried out does not have a negative impact on others. The readiness and thinking of a person can be seen from the age of an individual. The teenage phase occurs in someone at the age of 12 years to 18 years. At that age, an individual is in the middle or high school level. If a teenager feels school activities are not able to accommodate his thoughts, then he will overflow for less positive things. So teenagers should have the good emotional intelligence to control their emotions.This research is a descriptive study with a qualitative approach that aims to describe how the profile of thinking in solving mathematical problems based on the level of emotional intelligence. Subjects in this study were three students consisting of one student with high emotional intelligence, one student with moderate emotional intelligence, and one student with low emotional intelligence. In achieving these objectives the researchers conducted emotional intelligence tests, tests of mathematical problem solving, and interviews of the three subjects.The results showed that students with high emotional intelligence were able to solve mathematical problems with SPLTV material correctly, all information on the questions was used, writing steps to solve problems coherently and correctly, choosing the correct method to solve the problems. Emotionally intelligent students are less able to solve mathematical problems with SPLTV material correctly, because there is information on questions that are not used, and that results in choosing a method to solve the problem so that in solving it is less correct. Low emotional intelligence students are less able to solve mathematical problems with SPLTV material correctly because they are not able to remember previous knowledge, there is information on questions that are not used, the methods used are not correct, so in solving them less correct.Keywords: Thinking, Mathematics, and Emotional Intelligence.

Misconceptions in this research are analyzed based on its type, namely classification, correlation and theoretical misconceptions. Scaffolding in this research is explaining reviewing, and restructuring which consists of (1) looking, touching and verbalising (2) Pompting and probing (3) interpreting student's actions and talk, (4) parallelling modeling and (5) students explaining and justifyng, restructuring which consists of (1) identifying meaningful context (2) simplifying the problem (3) re-pharasing studdent's talk (4) negotiating meaning, developing conceptual thinking consisting of developing representational tools and making connections. Based on research conducted by researchers, there are 16.53% of classification misconceptions, 49.59% of correlation misconceptions exist and 49.59% of theoretical misconceptions. After being given scaffolding, students' misconceptions in solving the set material matter diminished and no longer even experienced misconceptions. Therefore, scaffolding is an alternative to responding to misconceptions experienced by students in solving set material problems. Keywords: Misconception, scaffolding, set.

Statistical reasoning is needed by students to understanding statistical concepts and problems. Students’ efforts in understanding statistical information and problems often involve statistical process, namely the process of organizing and reducing data and the process of analyzing and interpreting data.  This research is descriptive study with qualitative approach that aims to analyze and describe the senior high school students’ statistical reasoning in solving non-routine problems. The subjects in this study were three high school students of grade XII who have same sex and have equivalent mathematical abilities. The instruments used in this study consisted of the Mathematical Ability Test (MAT), the Statistical Reasoning Test (SRT), and interview guidlines. The results showed that students who have low mathematical ability are also reach low level in statistical reasoning. In solving problem related to process of organizing and reducing data, the students reached level 1 and level 2 in statistical reasoning, because the students determine the mode value using incorrect concepts and ways, that are input the data to the mode formula incorrectly, determining the mode value of data which are presented in the frequency distribution table just by looking at frequency column, and cannot combine and sort the data in percent form correctly. In solving the problem related to the process of analyzing and interpreting data, the students reached level 1 in statistical reasoning, because they cannot interpret the tendency of two data groups, so the response which are given is incorrect. Keywords: statistics, statistical process, statistical reasoning.

In implementing the 2013 curriculum, Higher Order Thinking Skills (HOTS) must be integrated into learning activities. Similarity are sub material of similarity and congruence that students must learn. In fact, the higher order thinking skills of junior high school students in similarity material is low. To overcome this problem, it is necessary to develop a learning materials for learning in the form of plane similarity according to the level of student thinking in geometry, which is based on Van Hiele's theory to improve students' higher-order thinking skills. Van Hiele's theory was chosen because it suggests the development of students' thinking in learning of geometry occurs through five levels sequentially so that learning devices can be developed according to the level of van Hiele students. The purpose of this research is to obtain a description of the learning materials of plane similarity based on van Hiele theory based on van Hiele theory to improve students' high-level thinking skills that are valid, practical, and effective. This type of research is a research development using the 4-D model proposed by Thiagarajan then simplified to a 3-D model. Validation of learning devices, participant observation, questionnaires, and tests are the data collection techniques used. The results showed that the RPP, LKS, and THB were said to be valid then, the learning materials was declared valid; the management of learning is said to be good, the overall evaluation on the validation sheet of the learning materials is stated to be used, and the percentage of active student activities at the second meeting and the third meeting respectively is 91.25% and 91.25% then, the learning kit is declared practical; and the percentage of positive responses of students by 71% and an increase in higher order thinking skills seen from the results of the N-Gain pretest and posttest of 0,728 categorized as high then, the learning device is declared effective. Keywords: learning materials, plane similarity, van hiele’s theory, higher order thinking skills.

Aljabar merupakan salah satu materi matematika yang wajib dipelajari oleh siswa, karena materi ini mempunyai keterkaitan dengan materi matematika yang lain misalnya kalkulus, geometri, statistika dan peluang, dan lain sebagainya. Dengan demikian, kemampuan berpikir aljabar siswa perlu dikembangkan dengan cara melatih siswa berpikir aljabar. Kemampuan berpikir aljabar siswa dapat dilihat berdasarkan pencapaian indikator kemampuan berpikir aljabar dari tiap-tiap aktivitas berpikir aljabar. Aktivitas berpikir aljabar terdiri dari generalisasi, abstraksi, berpikir dinamis, pemodelan, berpikir analitis, dan organisasi. Kemampuan berpikir aljabar adalah kesanggupan siswa berpikir matematis yang meliputi generalisasi, abstraksi, berpikir analitis, berpikir dinamis, pemodelan, dan organisasi. Kemampuan berpikir aljabar siswa tentunya berbeda-beda. Perbedaan tersebut dipengaruhi oleh kemampuan matematika siswa dan jenis kelamin. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif dengan tujuan untuk mendeskripsikan kemampuan berpikir aljabar siswa SMP dalam menyelesaikan masalah matematika ditinjau dari perbedaan jenis kelamin. Metode pengumpulan data melalui tes tertulis dan wawancara. Tes tertulis terdiri dari tes kemampuan matematika dan tes kemampuan berpikir aljabar. Tes kemampuan matematika digunakan untuk memperoleh subjek penelitian. Subjek penelitian yaitu satu siswa laki-laki dan satu siswa perempuan dengan kemampuan matematika tinggi yang setara kelas VIII SMPN 32 Surabaya. Hasil penelitian ini menujukkan perbedaan kemampuan berpikir aljabar siswa laki-laki dan siswa perempuan. Siswa laki-laki dapat memenuhi indikator kemampuan berpikir aljabar dari lima aktivitas berpikir aljabar yaitu generalisasi, berpikir dinamis, abstraksi, pemodelan, dan berpikir analitis.
