Educational Methods and OutcomesScience Education and Pedagogy
Abstract
Student learning outcomes are influenced not only by content mastery but also by the way instruction is designed and implemented. The experimental method allows students to observe phenomena, formulate predictions, conduct experiments, collect evidence, and draw conclusions. This article discusses how experimental learning may improve student outcomes and identifies conditions that support its implementation. A narrative literature review was conducted using education research articles, particularly studies on experimental methods in elementary science and integrated science-social studies learning. The reviewed literature suggests that experiments can support engagement, conceptual understanding, and achievement when learning objectives, worksheets, classroom management, teacher guidance, and assessment are well aligned. Nevertheless, experiments are not automatically effective in every context. Planning quality, equipment availability, safety, facilitation of discussion, and student characteristics influence the results. The article recommends structured and reflective experiments accompanied by pre- and post-learning assessment. As a literature review, this article does not report new field data; its conclusions are limited to the sources examined.
This publication proposes a definition and a classification of agile software development approaches and analyses ten software development methods that can be characterized as being "agile" against the defined criterion.

The study shows that agile practices improve both informal and formal communication, but indicates that, in larger development situations involving multiple external stakeholders, a mismatch of adequate communication mechanisms can sometimes even hinder the communication.

It is proved that any global minimizer of the trajectory balance objective can define a policy that samples exactly from the target distribution, and empirically demonstrate the benefits of the trajectories balance objective for GFlowNet convergence, diversity of generated samples, and robustness to long action sequenc...
