<p><strong>Abstract:</strong> This research was aimed to describing the mistakes made by the eighth grade students of SMPN 2 Tiris in Probolinggo district in solving the story problems related to the Pythagorean Theorem. Three subjects were selected to solve the story problem of the Pythagorean Theorem then interviewed. The analysis used was based on conceptual error, procedural and calculation. The results showed that in the conceptual stage the subject made a mistake in drawing a right triangle and determining the sloping side. Procedural errors are made, namely the subject makes a withdrawal of the root in the right segment even though in the left side is still a square. While at the calculation stage the subject made a mistake in determining the results of the square root and the difference so that it was wrong in the final result.</p><strong>Abstrak:</strong><em> </em>Penelitian ini bertujuan untuk mendeskripsikan kesalahan yang dilakukan siswa kelas VIII SMPN 2 Tiris Kabupaten Probolinggo dalam menyelesaikan soal cerita terkait Teorema Pythagoras.

Definiteness Effect

Abstract This paper explores fronted verb phrases in German, drawing attention to the difference between passive/unaccusative VPs and fronted agentive vPs. While both kinds of verb phrases have been discussed in the literature as being frontable, it has been largely overlooked that fronted vPs typically come with a certain kind of post-fronting context and a rise-fall or bridge-contour intonation, which is characteristic of I-topicalization. We observe that, unlike VPs, agentive vPs essentially need to be I-topics, with a high tone at the right edge of the fronted domain, in order to be frontable. Given the special context required for fronted vPs, the situation described by the vP does not contain new information but must already have been under discussion and is now being commented on. We present the results of two experimental studies and appeal to the thetic/categorical distinction to offer a new angle on the definiteness effect that has been associated with fronted verb phrases. We propose that a subject-containing fronted vP is associated with a thetic rather than the default categorical judgment, which means that the fronted subject and predicate form only one information-structural unit (a topic) rather than two (topic and comment). Contributing to the literature on theticity, we observe that, unlike in non-fronting thetic statements, the subject in fronted vPs cannot be a true definite. We attribute this to clashing intonation restrictions on theticity in non-fronting constructions versus theticity in just the fronted portion of a sentence.

This research was aimed to determine the understanding concept of students in solving mathematics story problems CRI in terms of personality types. The research method was descriptive qualitative. Subjects in this research ware as many as 4 students, each 2 students with Extrovert personality types and 2 students with introverted personality types. Technique of Data collecting in this research using questionnaire instrument of personality type, about written story and interview. Based on the data analysis, the results of research indicate that: (1) the understanding concept of subject with extrovert personality type is at the level of ability of translation and interpretation. In solving the mathematical story problems, they are able to identify, present and apply the broad concept and circumference of the circle and provide a high CRI scale. Extrovert personality type shows that solving the subject matter is not careful, in a hurry as to dare to take risks from the work, done and to underestimate a thing, and to like the practical things. (2) the understanding concept of subject with introverted personality type is at the level of translation ability. In solving the mathematical story, they are only able to identify and present the concept of circles and provide a low CRI scale. According introverted personality type that shows in solving the subject matter are meticulous, careful, careful in solving the story problem, causing the subject with introverted personality type to be shy and not confident with the answers they write.

ABSTRACT The purpose of this study is to describe the sentences in the explanatory text of students in terms of four things. First, the effectiveness of sentences in terms of structural clarity, there are 78 (19.60%) errors. The ineffectiveness of the sentence is in the active / passive structure (1 error), the subject is not an explanation (21 errors), the predicate is not lost (28 errors), the description is not in the form of a subject (4 errors), and the subject is not lost (25 errors). Second, the effectiveness of sentences in terms of logical meaning there are 76 (19.09%) errors. The ineffectiveness of the sentence lies in the logical relationship S and P (52 errors) and the logical relationship of details or parallel meaning (23 errors). Third, the effectiveness of sentences in terms of word saving is 142 (35.68%) errors. The ineffectiveness of the sentence is on one subject from the same subject (46 errors), one word from several synonymous words (21 errors), and the required word (115 errors). Fourth, the effectiveness of sentences in terms of word rigidity there are 102 (25.63%) errors. Based on these results it can be concluded that the sentences in the explanatory text of eighth grade students of SMP Pembangunan Laboratorium Laboratory are not effective. This is evidenced from the 221 sentences studied, there were 31 (14.03%) effective sentences and 190 (85.97%) ineffective sentences with 398 errors. Kata kunci: Keefektifan Kalimat, Teks Eksplanasi

The paper deals with the category of “values”, the right as a value, and fundamental values of law; including freedom, justice, and equality are analyzed.The relevance of the research is determined not only by the apparent lack of exploration of the problem but also by the fact that the value of right and legal values determine direction and meaning, as well as the content of the rules of law, which is their normative expression, and, ultimately, appearing as a kind of basis for the legal culture, the source of the legal consciousness’s formation and establishing a legal order, ensuring the efficiency of legal regulations due to the using the embodiment in reality of freedom, justice, equality.Legal norms themselves acquire the importance of values and become the subject of evaluation. Among values themselves, which act as an ideal justification of the rules of law, the rules of law themselves and assessments, on the one hand, there are not only close ties but also mutual transitions. Therefore, both their interrelated explanations and differentiation are necessary.In this regard, the role and importance of rights and of the abovestated legal values, including the historically-legal aspect, their historical conditionality are disclosed, the semantic content and the importance in the establishment of the legitimacy regime are analyzed, the points of view expressed in the  research literature on the nature of legal values, signs, hierarchy,  the role in social and normative regulation are considered, the difference between value and the object of value or good is emphasized.
