Abstract

This study investigates the comparative efficacy of Summated Rating Scales (SRS) and traditionalordinal scales (raw Likert-type responses) in measuring critical thinking skills among vocationalstudents, employing Item Response Theory (IRT) to evaluate their psychometric properties.Addressing the limitations of ordinal scales notably inconsistent intervals between responsecategories the research adopts a descriptive quantitative methodology involving 269 students fromstate vocational high schools in Yogyakarta, Indonesia. Data were collected using a five-pointLikert scale instrument, validated for content (Aiken’s V = 0.94), and analyzed through two IRTframeworks: Polytomous IRT for unscaled ordinal data and Continuous Response Model (CRM)IRT for SRS-transformed interval data. Key findings reveal that SRS enhances measurementprecision by normalizing response distributions into proportional intervals (e.g., recalibrated scores:0.00, 0.73, 1.46, 2.07, 2.84), thereby resolving issues of unequal category spacing inherent toordinal scales. Polytomous IRT demonstrated robust item fit (e.g., Partial Credit Model fit for 5/6items) and strong difficulty parameter invariance (r = 0.84), yet exhibited instability in abilityestimates (r = 0.37) due to extreme response patterns. Conversely, CRM IRT applied to scaleddata produced stable ability estimates (r = 0.46) and eliminated infinite values in MaximumLikelihood Estimation, underscoring its superiority in handling continuous metrics. However, ordinalscales retained higher consistency in difficulty calibration across subgroups. The study concludesthat integrating SRS with CRM IRT offers a refined approach for critical thinking assessments,balancing precision and fairness, while ordinal scales remain pragmatic for contexts prioritizingsimplicity. These insights advocate for the adoption of advanced scaling techniques in vocationaleducation to improve the validity of competency evaluations, with recommendations for futureresearch to explore hybrid models and longitudinal applications.

Abstract

The use of Google Forms as a learning tool in certain subjects is massively used in several schools because of its efficiency. This research aims to identify, classify, and observe literature, synthesize several studies that have been carried out, analyze the contributions that have been made, and propose related research updates. This study uses a methodology supported by a research approach, documentation, and procedural models from systematic literature review and data analysis using quantitative and qualitative descriptive analysis techniques. The results of this study show the effectiveness of Google Forms on the assessment and eval_uation of student learning outcomes, which from the table has proven that there are 36 studies (90%) that agree that the use of Google Forms has a positive or effective influence on success in assessing and eval_uating learning outcomes. This conclusion underscores the importance of digital marketing in the modern technology era. Digital marketing allows businesses to effectively reach global audiences through social media, SEO, and content. In this study, it was seen that a good digital strategy can increase brand awareness and customer loyalty. By utilizing proper data analysis, companies can optimize their digital marketing campaigns for better results. In conclusion, digital marketing is the key to winning the competition in an increasingly competitive market.
