It was requested that 154 senior high school teachers from 20 different senior high schools reply to a questionnaire containing 12 items. According to the results of an independent sample t-test, male teachers have significantly stronger self-efficacy views than their female colleagues. Again, the results of a one-way analysis of variance (ANOVA) test reveal that there was no statistically significant difference between the means of the five groups of teacher teaching experience in terms of teacher efficacy. Teachers should take part in ongoing professional development activities to make sure they are still good at their jobs.
Abstract:Evaluasi kinerja pegawai honorer di instansi publik seringkali bergantung pada penilaian linguistik yang subjektif, sehingga memicu bias penilai dan keterbatasan akuntabilitas. Untuk mengatasi masalah tersebut, penelitian…
n ini mengusulkan model hibrida Fuzzy-Weighted Product. Logika Fuzzy diterapkan untuk mentransformasikan istilah linguistik menjadi Triangular Fuzzy Numbers (TFN) dan skor tegas (crisp), sementara metode Weighted Product digunakan untuk mengagregasikan skor tersebut berdasarkan bobot multi-kriteria. Model ini dievaluasi melalui studi kasus yang melibatkan sepuluh pegawai honorer berdasarkan lima kriteria: disiplin, tanggung jawab, kualitas kerja, kerja sama, dan inisiatif. Hasil eksperimen menunjukkan bahwa model hibrida ini berhasil meminimalkan subjektivitas penilai dan menghasilkan perengkingan yang dapat direproduksi secara matematis. Analisis sensitivitas mengonfirmasi stabilitas hasil peringkat akhir, sehingga model Hibrida Fuzzy Weighted Product yang diusulkan ini sangat sesuai untuk digunakan sebagai kerangka kerja utama dalam sistem pendukung keputusan untuk penilaian kinerja di sektor publik.
Performance evaluation of honorary employees in public institutions often relies on subjective linguistic assessments, leading to evaluator bias and limited accountability. To address this, this paper proposes a Hybrid Fuzzy-Weighted Product (Fuzzy-Weighted Product) model. Fuzzy Logic is adopted to transform linguistic terms into Triangular Fuzzy Numbers (TFN) and crisp scores, while the Weighted Product method aggregates these scores based on multi-criteria weights. The model was evaluated using a case study of ten honorary employees across five criteria: discipline, responsibility, work quality, cooperation, and initiative. The experimental results demonstrate that the hybrid model successfully minimizes evaluator subjectivity and delivers mathematically reproducible rankings. A sensitivity analysis confirms the stability of the final rankings, making the proposed Hybrid Fuzzy–Weighted Product model highly suitable as a core framework for decision-support systems in public sector performance appraisal.
Abstract:This study aims to identify the dominant error patterns of students in geometry learning based on Newman's Error Analysis (NEA) and to examine their implications for readiness to understand Non-Euclidean Geometry. The method…
thod employed is a Systematic Literature Review (SLR) of 10 empirical articles published between 2019 and 2026. Data were extracted based on the five stages of NEA — reading, comprehension, transformation, process skill, and encoding — and subsequently analyzed through narrative synthesis, percentage comparison, and descriptive effect size. The results indicate that comprehension errors and encoding errors are the most dominant categories, with the highest percentages of 56.92% and 50%, respectively, followed by transformation errors, which consistently fall within a moderate effect range (20–40%), while reading errors and process skill errors are classified as low. The primary causes of errors include weak understanding of geometric concepts, inability in spatial visualization, limited mathematical language, and lack of procedural precision. The findings contribute as a diagnostic foundation for designing more effective geometry learning, while simultaneously serving as a conceptual bridge toward higher-level geometry

Abstract:This study aims to examine the application of the High-Low method, Scatterplot, and Least Squares in cost analysis, particularly in separating fixed and variable cost behavior. The research uses a library research approach…
ch by collecting and reviewing literature from textbooks, journals, and official publications related to cost estimation and cost behavior modeling. The findings indicate that the High-Low method is simple because it uses only the highest and lowest activity levels, but its accuracy is limited due to reliance on extreme data points. The Scatterplot method provides a visual representation of the relationship between cost and activity, helping identify patterns and potential outliers; however, its results may vary due to subjective judgment in determining the cost line. Meanwhile, the Least Squares method is considered the most accurate because it utilizes all available data to produce the best-fit regression line, although it requires more complex calculations and statistical understanding. Overall, the selection of the most suitable method depends on the objective of the analysis, data availability, and the level of accuracy required

Abstract:This study examines how thematic organization contributes to the construction of state power and social positioning in international news discourse. Drawing on Halliday’s Systemic Functional Linguistics, with a specific…
c focus on Theme–Rheme structure, the study analyses a BBC news report published in November 2023 on the Russian Supreme Court’s decision to designate the so-called “international LGBT movement” as an extremist organization. Using a qualitative textual approach, the text is segmented into clauses and analyzed to identify patterns of thematic choice and progression. The findings reveal a consistent foregrounding of institutional actors, such as state authorities and legal bodies, in Theme position when reporting legal actions and policy decisions, while members of the LGBT community and civil society figures are predominantly thematized in clauses expressing reactions, personal experiences, and anticipated consequences. This asymmetric thematic distribution constructs a discourse in which state authority is positioned as the primary agent of action, whereas affected social groups are framed as respondents to institutional power. The study demonstrates that ideological meanings in news discourse may be realized implicitly through grammatical organization rather than explicit evaluative language, and it highlights the value of Theme–Rheme analysis for examining power relations in contemporary international news reporting.
