Abstract

Work engagement is a positive psychology construct widely sought after and developed in various countries. Psychometric validation requires statistical analysis to measure and differentiate individuals across different cultures. This study aims to validate the Utrecht Work Engagement Scale-17 (UWES-17) instrument on hospitality workers in state-owned companies in Indonesia. The study population comprised 3185 individuals, representing various positions and types of hospitality service jobs within the land transportation sector of a state-owned enterprise. A non-probability sampling approach, specifically convenience sampling, was employed, selecting participants based on their accessibility and willingness to participate. The participants, aged between 18 and 62, came from diverse fields and work areas. Analysis of item responses in the test was the Rasch Model with a study focus on item fit and person fit from the UWES-17 Scale. In addition, assumption tests of unidimensionality and local independence were performed to ensure the validity of the measurement model. The scale’s reliability was also assessed to evaluate the instrument’s consistency. The results showed that the items were overall fit, but the criteria for person fit were unmet. This is due to the tendency for uniformity and too many diverse positions and cultural tendencies of state-owned companies. The implication is that further item development and confirmation are needed on the constituent aspects, especially the absorption constituent items. Additionally, developing a more consistent shorter version or discovering other dimensions of work engagement that are specific to collectivist societies may be possible.

Abstract

AbstractCurriculum reform plays an essential role in assuring the success of systematic educational change. The purpose of this study is to portray the government policy and the issues of the Curriculum 2013 implementation. This study employed qualitative methodology using document analysis, observation and Focused Group Discussion (FGD)   as data collection techniques. The results of this study show that the curricula philosophy of curriculum reform was well-articulated and relevant to meet the requirements of twenty-first century learning competencies. However, the curricula implementation process faced substantial challenges with technical problems regarding the national standards of education document, teacher training and competences, the availability of school textbooks, and classroom assessment implementation. The findings of this study have several implications for implementing the national curriculum in Indonesia. Therefore, alignment between the national standards of education document, the curriculum structure, and the assessment system is required in order to ensure the successful implementation of Curriculum 2013 throughout the nation.AbstrakReformasi kurikulum memainkan peran penting dalam memastikan keberhasilan perubahan pendidikan yang sistematis. Tujuan dari penelitian ini adalah untuk menggambarkan kebijakan pemerintah dan isu-isu implementasi Kurikulum 2013. Penelitian ini menggunakan metodologi kualitatif menggunakan analisis dokumen, observasi dan diskusi kelompok terpumpun sebagai teknik pengumpulan data. Hasil penelitian ini menunjukkan bahwa filosofi reformasi kurikulum diartikulasikan dengan baik dan relevan untuk memenuhi persyaratan kompetensi pembelajaran abad kedua puluh satu. Namun, proses implementasi kurikulum menghadapi tantangan besar dengan masalah teknis mengenai dokumen yang terkait dengan standar nasional pendidikan, pelatihan dan kompetensi guru, ketersediaan buku pelajaran di sekolah, dan implementasi penilaian di dalam kelas. Temuan penelitian ini memiliki beberapa implikasi untuk menerapkan kurikulum nasional di Indonesia. Oleh karena itu, diperlukan keselarasan antara dokumen standar nasional pendidikan, struktur kurikulum, dan sistem penilaian untuk memastikan keberhasilan implementasi Kurikulum 2013 di seluruh negara.

Abstract

Studi ini menggunakan simulasi Monte Carlo dilakukan untuk melihat pengaruh ukuran sampel dan intraclass correlation coefficients (ICC) terhadap bias estimasi parameter multilevel latent variable modeling. Kondisi simulasi diciptakan dengan beberapa faktor yang ditetapkan yaitu lima kondisi ICC (0.05, 0.10, 0.15, 0.20, 0.25), jumlah kelompok (30, 50, 100 dan 150), jumlah observasi dalam kelompok (10, 20 dan 50) dan diestimasi menggunakan lima metode estimasi: ML, MLF, MLR, WLSMV dan BAYES. Jumlah kondisi keseluruhan sebanyak 300 kondisi dimana tiap kondisi direplikasi sebanyak 1000 kali dan dianalisis menggunakan software Mplus 7.4. Kriteria bias yang masih dapat diterima adalah < 10%. Hasil penelitian ini menunjukkan bahwa bias yang terjadi dipengaruhi oleh ukuran sampel dan ICC, penelitian ini juga menujukkan bahwa metode estimasi WLSMV dan BAYES berfungsi lebih baik pada berbagai kondisi dibandingkan dengan metode estimasi berbasis ML.Kata kunci: multilevel latent variable modeling, intraclass correlation coefficients, Metode Markov Chain Monte Carlo THE IMPACT OF SAMPLE SIZE AND INTRACLASS CORRELATION COEFFICIENTS (ICC) ON THE BIAS OF PARAMETER ESTIMATION IN MULTILEVEL LATENT VARIABLE MODELING: A MONTE CARLO STUDYAbstractA monte carlo study was conducted to investigate the effect of sample size and intraclass correlation coefficients (ICC) on the bias of parameter estimates in multilevel latent variable modeling. The design factors included (ICC: 0.05, 0.10, 0.15, 0.20, 0.25), number of groups in between level model (NG: 30, 50, 100 and 150), cluster size (CS: 10, 20 and 50) to be estimated with five different estimator: ML, MLF, MLR, WLSMV and BAYES. Factors were interegated into 300 conditions (4 NG  3 CS  5 ICC  5 Estimator). For each condition, replications with convergence problems were exclude until at least 1.000 replications were generated and analyzed using Mplus 7.4, we also consider absolute percent bias <10% to represent an acceptable level of bias. We find that the degree of bias depends on sample size and ICC. We also show that WLSMV and BAYES estimator performed better than ML-based estimator across varying sample sizes and ICC's conditions.Keywords: multilevel latent variable modeling, intraclass correlation coefficients, Markov Chain Monte Carlo method

Abstract

The Revised Life Orientation Test (LOT-R) is one of the most popular instruments for measuring optimism. The authors conducted a meta-analysis, also known as a reliability Generalization study, to estimate the population Cronbach's Alpha for the LOT-R. This study also examined Alpha heterogeneity and identified factors that might influence it. Using a Random Effects Model, the estimated population Cronbach's Alpha based on 211 studies was found to be 0.768 (95% CI: 0.757, 0.778), indicating a good level of reliability. The heterogeneity analysis revealed an I² value of 95.84%, suggesting significant differences among the studies. These differences may stem from factors beyond just methodological variations or population samples. To understand the possible causes for this heterogeneity, a meta-regression analysis was performed, focusing on moderator variables including gender, age, study setting, study type, citation, and language. Among these moderator variables, only the language variable showed a significant impact on the variation in Cronbach's Alpha. In conclusion, the findings suggest that the LOT-R is a reliable instrument for measuring optimism. However, the study also reveals that linguistic factors may influence its reliability, potentially limiting the generalizability of findings across different language groups and in cross-cultural contexts. Therefore, researchers should consider language-related variations when interpreting LOT-R results. Future studies are encouraged to examine further how linguistic differences may affect the instrument's validity and to explore ways to optimize its use across diverse cultural settings.
