The ability to solve physics problems that require multiple concepts from across the physics curriculum--"synthesis" problems--is often a goal of physics instruction. Three experiments were designed to evaluate the effectiveness of two instructional methods employing worked examples on student performance with synthesis problems; these…

With the introduction of "Next Generation Science Standards" ("NGSS"), teachers have been called to find meaningful and engaging ways to teach science content while incorporating engineering practices and, to a lesser extent, computing and computational thinking. The task becomes even more complex when they also have to…

National calls in science, technology, engineering, and technology education reform efforts have advanced the wide-scale engagement of students in undergraduate research for the preparation of a workforce and citizenry able to attend to the challenges of the 21st century. Awareness of the potential benefits and costs of these experiences has led…

Traditional modes of chemistry education in schools focus on imparting chemistry knowledge to students via instruction. Consequently, students often acquire the mistaken understanding that scientific knowledge comprises a fixed body of "proven" facts. They fail to comprehend that the construction of scientific understanding is a human…

Discusses research on middle school science learning and instruction that suggests how generative models of scientific phenomena can be developed. The Computer as Learning Partner curriculum is introduced as a curriculum that provides a firm foundation for lifelong learning through the use of authentic questions. (SLD)

The role of performance assessments in making cognitive activity apparent to teachers and students was studied through descriptions of the cognitive activity of 31 fifth-grade students. Differences while carrying out a science performance assessment reveal critical differences between those who think and reason well with their knowledge of…

From the late 1950s through today, hands-on science has been promoted as a method of science instruction. Currently, recent national science reform efforts seek to temper its role. However, no consensus has been reached on the relationship of hands-on science to student achievement, though this has been researched since the turn of the 20th…

This article describes an alternative way of testing--a performance assessment--that is different both in process and goals from typical tests, but closer to what teachers believe assessment should be. Teachers who have helped to create, refine, and use this new generation of tests find them valuable because they measure the skills and concepts…

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

This study examined the relative effect of a HyperCard based approach to solving stoichiometric equations using Hyperequation, and traditional pen-paper methods on the performance of expert and novice high school chemistry students. Hyperequation is programmed to register student responses, provide immediate feedback, and keep a record of all the…

Results of a HyperCard method for assessing the performance of expert and novice high school chemistry students solving stoichiometric chemistry problems (balancing chemical equations) is reported. MANOVA results indicate significant difference between expert and novice students solving the five stoichiometric chemistry problems using…

Describes the selection and implementation of an authentic assessment model for evaluating students' science laboratory knowledge and skills. Provides sample problems and a scoring form for the performance-based science laboratory test. (MDH)

Presents the science demonstration assessment as an authentic- assessment technique to assess whether students understand basic science concepts and can use them to solve problems. Uses rubrics to prepare students for the assessment and to assign final grades. Provides examples of science demonstration assessments and the scoring of rubrics in the…

Hands-on science activities and first-hand experiences of kindergartners studying trees demonstrate the true meaning of authentic assessment. The activities and teacher interactions had several things in common: (1) they asked students to perform or create something; (2) they invoked real-world applications; (3) they showed that there is more than…

Educational systems promote student growth in a variety of dimensions. Basic content knowledge can be effectively assessed with multiple-choice and completion tests. However educational reforms have become more concerned with higher-order cognitive dimensions (problem-solving, creativity), social dimensions (communication skills, ability to work…
