Abstract

This study aims to examine how the process of problem-based learning emphasizes creativity, cooperative learning, critical thinking, and idea development. The instruments used in these assessments cannot reflect the principles inherent in the problem-based learning method, which prioritizes contextual and daily-life applications. The objectives of this study aim to validate the developed product using ADDIE model, focusing on the outcomes of assessments by instrument and learning evaluation experts. The results of this study showed that the assessment instrument was categorized as very feasible by experts with an average score of 4.59 of 5 as maximum score. The learning evaluation expert assessment score was 4.71, and the instrument expert assessment was 4.47. Thus, it can be stated that the products developed are valid and suitable for use by target group. Valid and feasible instruments are expected to provide more accurate student learning assessment results according to learning objectives.

Abstract

This study examines the development and validation of a non-test instrument for assessing the Problem-Based Learning (PBL) model in vocational high schools, specifically within the Office Management and Business Services (OMBS) program. The instrument covers seven constructs: problem identification, fact identification, hypothesis formulation, self-directed learning, collaboration and cooperation, solution determination, and evaluation of the problem-solving process. This study uses a quantitative method with a Confirmatory Factor Analysis (CFA) approach to test the validity and reliability of the instrument. Using probability sampling with simple random sampling, 372 respondents (30 teachers and 342 students) from vocational schools in Surabaya participated. Data analysis was conducted using SPSS 16 for reliability testing and LISREL 8.8 for CFA. Results showed high internal consistency (Cronbach's Alpha = 0.949) and satisfactory anti-image coefficients (>0.5), indicating that the data met the requirements for factor analysis. The results of the model fit test also showed that the developed CFA with modification indices model met the criteria for a good fit with a Chi-square value of 170.51 with a degree of freedom (df) of 110, producing a p-value = 0.00019, an RMSEA value of 0.039 <0.08. The validity and reliability of the constructs in each instrument indicator also prove that this model meets a good fit with the resulting value above 0.5. Thus, this non-test instrument is worthy of being used as an assessment standard for evaluating problem-based learning in vocational high schools in the OMBS program to improve the quality of student learning outcomes.
