Abstract

Problem-Based Learning has been studied over three decades in various subjects and schools, This meta-analysis study aimed to synthesize the most recent findings of the effect of Problem-Based Learning (PBL), specifically on students’ mathematical reasoning ability. The data were obtained from relevant primary studies published in national and international journals or proceedings during 2014-2021. Ten effect sizes from eight studies that fulfilled the inclusion criteria were analyzed using a systematic review and meta-analysis. JASP 0.15.0.0 software was used to measure the formula of Hedges g to determine the effect size. The result showed that PBL has a strong effect on students’ mathematical reasoning ability (g­­RE = 2.062, 95% CI [1.436, 2.689], p 0.001) when compared to traditional learning. The results of the analysis of moderator variables revealed that publication year (Qb = 5.460, p 0.05) and sampling technique (Qb = 9.032, p 0.05) had significant effect on the effectiveness of PBL on students’ mathematical reasoning ability, while educational levels (Qb = 1.649, p 0.05), sample size (Qb = 2.081, p 0.05) and publication sources (Qb = 0.573, p 0.05) did not show any significant effect. The result of this study provides important information for further meta-analysis study and the implementation of PBL in mathematics learning.

Abstract

The study aims to identify the manifestation of Character Based Education Pandemic in internationalization Dynamics. It also explore concept of character as a part of pandemic process throughout human life and investigate on how pandemic plays role in character. In order to meet the purpose of the research, the qualitative approached, as it is in line with this particular study which is descriptive in nature. In accordance with many of the previous theories regarding the character based education in pandemic, it is found that the application of Character Based Education Pandemic of internationalization dynamics to be a better character. Improvement and successful program indirectly derived from manifestation of the characteristics of Character Based Education Pandemic namely faith in oneself, the aspiration towards excellence, the tenacity to challenge themselves, the engagement of support from others, and the continuous deliberate practice. Through the act of character based education, internationalization dynamics will evolve toward the betterment and so will the organization.

Abstract

In item response theory, the number of response categories used in polytomous scoring has an effect on the fit of the model used. When the initial scoring model yields unsatisfactory estimates, corrections to the initial scoring model need to be made. This exploratory descriptive study used response data from Take Home Exam (THE) participants in the Statistical Methods I course organized by the Open University, Indonesia, in 2022. The stages of data analysis include coding the rater’s score; analyzing frequency; analyze the fit of the model based on graded, partial, and generalized partial credit models; analyze the characteristic response function (CRF) curve; scoring correction (rescaling); and re-analyze the fit of the model. The fit of the model is based on the chi-square test and the root mean square error of approximation (RMSEA). All model fit analyzes were performed by using R. The results revealed that scoring corrections had an effect on model fit and that the partial credit model (PCM) produced the best item parameter estimates. All results and their implications for practice and future research are discussed.

Abstract

Scoring quality has been recognized as one of the important aspects that should be of concern to both test developers and users. This study aimed to investigate the effect of scoring correction and model fit on the estimation of ability parameters and person fit in the polytomous item response theory. The result of 165 students in the Statistics course (SATS4410) test at one of the universities in Indonesia was used to answer the problems in this study. The polytomous data obtained from scoring the test results were analyzed using the Item Response Theory (IRT) approach with the Partial Credit Model (PCM), Graded Response Model (GRM), and Generalized Partial Credit Model (GPCM). The effect of scoring correction and model fit on the estimation of ability and person fit was tested using multivariate analysis. Among the three models used, GRM showed the best fit based on p-value and RSMEA. The results of the analysis also showed that there was no significant effect of scoring correction and model fit on the estimation of the test taker’s ability and person fit. From the results of this study, we recommend the importance of evaluating the levels or categories used in scoring student work on a test.

Abstract

Penelitian ini bertujuan untuk meningkatkan toleransi siswa dalam pembelajaran matematika menggunakan model guided discovery setting pembelajaran kooperatif tipe TPS pada kelas X MIPA 5 MAN Yogyakarta 3. Penelitian ini adalah penelitian tindakan kelas yang dilaksanakan sebanyak 2 siklus, dimana setiap siklusnya terdiri dari tahap perencanaan (planning), tindakan (action), pengamatan (observation), dan refleksi (reflection). Hasil penelitian menunjukkan bahwa untuk meningkatkan toleransi siswa dalam pembelajaran matematika menggunakan model pembelajaran guided discovery setting pembelajaran kooperatif tipe TPS dapat dilakukan dengan cara: (a) pembagian kelompok yang terdiri dari keragaman tingkat kemampuan akademik, gender, suku, ras, dan budaya; (b) mendorong setiap siswa untuk mengemukakan pendapat dalam menyelesaikan masalah, baik secara tertulis maupun lisan; (c) membiasakan siswa membuat kesepakatan untuk menentukan jawaban/penyelesaian terbaik, apabila terdapat perbedaan jawaban/penyelesaian dari suatu masalah; dan (d) menyajikan masalah terbuka yang menuntut beragam cara penyelesaian dan atau beragam jawaban, agar siswa terbiasa saling berargumen, saling mendiskusikan, saling memberi dan menerima saran dan kritik, serta saling menghargai satu sama lain.

Abstract

Three popular models are used to describe the characteristics of the test items and estimate the ability of examinees under the dichotomous IRT model, namely the one-, two-, and three-parameter logistic models. The three-item parameters are discriminating power, difficulty, and pseudo-guessing. In the development of the dichotomous IRT model, carelessness or upper asymptote parameter was proposed, which forms a four-parameter logistic (4PL) model to accommodate a condition where a high-ability examinee gives an incorrect response to a test item when he/she should be able to respond to the test item correctly. However, the carelessness parameter and the 4PL model have not been widely accepted and used due to several factors, and people’s understanding of that parameter and strategies for estimating it is still inadequate. Therefore, this study aims to shed light on ideas underlying the 4PL model, the meaning of the carelessness parameter, and strategies used to estimate that parameter based on the extant literature. The focus of this study was then extended to demonstrating practical examples of estimating item and person parameters using the 4PL model using empirical data on responses of 1,000 students from the Indonesia Open University (Universitas Terbuka) on 21 of 30 multiple-choice items on the Business English test, a paper-and-pencil test. We mainly analyzed empirical data using the ‘mirt’ package in RStudio. We present the analysis results coherently so that IRT users would have a sufficient understanding of the 4PL model and the carelessness parameter, and they can estimate item and person parameters under the 4PL model.
