There are various types of instructional media related to Valence Shell Electron Pair Repulsion (VSEPR) but there is a lack of diversity of resources devoted to assessment. This research presents an assessment and comparison of students' understanding of VSEPR theory before and after tuition involving the use of the foam molecule model (FMM) and…

The instruction of Natural Science subject in junior high schools, as regulated by 2013 Curriculum, is to be taught in an integrated way, combining Biology, Physics, and Chemistry subjects. The assessment of which is called authentic assessment. This current study described the instructional system especially the assessment system of Natural…

National goals and performance standards were introduced in Sweden during the 1990s as part of a curriculum reform. The intention was to detect shortcomings among students and provide support to those students who did not reach the passing grade in one (or several) subject/s. Despite this reform, approximately one-fourth of the students do not…

K-12 teachers of science have been digging into the "Next Generation Science Standards" ("NGSS") (NGSS Lead States 2013) to begin creating plans and processes for translating them for classroom instruction. As teachers learn about the NGSS, they have asked about the general structure of the standards document and how to read…

K-12 teachers of science have been digging into the "Next Generation Science Standards" (NGSS) (NGSS Lead States 2013) to begin creating plans and processes for translating them for classroom instruction. As teachers learn about the "NGSS," they have asked about the general structure of the standards document and how to read…

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…

This paper illustrates the use of simulation-based performance assessment (PA) methodology in a recent study of eighth-grade students' understanding of physical science concepts. A set of four simulation-based PA tasks were iteratively developed to assess student understanding of an array of physical science concepts, including net force,…

In the context of future of academic librarianship terms such as "blended" and "embedded" librarian have been used to describe emerging greater levels of involvement within the universities enterprise. Simultaneously new pedagogical approaches are being developed towards more authentic and engaging learning experiences. This…

Increase in tuition fees means there will be renewed pressure on universities to provide "value for money" courses that provide extensive training in both subject-specific and generic skills. For graduates of chemistry this includes embedding the generic, practical, and laboratory-based skills associated with industrial research as an…

The study reports the evaluation and analysis of the implementation of the Nature Environment Exploration approach in the Department of Biology, Universitas Negeri Semarang State University. The method used was survey method. The results showed that the implementation of the Nature Environment Exploration approach was still far from optimal…

Science teacher educators in the United States are currently preparing future science teachers to effectively implement the "Next Generation Science Standards" (NGSS) and, in thirteen states, to successfully pass a content-specific high stakes teacher performance assessment, the edTPA. Science education and teacher performance assessment…

This research study compared learning of 6-9th grade deaf students under two modes of educational delivery--interpreted vs. direct instruction using science lessons. Nineteen deaf students participated in the study in which they were taught six science lessons in American Sign Language. In one condition, the lessons were taught by a hearing…

How do teachers ignite a fire that kindles a love for books and produces a sense of wonder in the science classroom? What do teachers know and do that lights that spark in their students (Cummins 2012)? In this article, science and mathematics professor Sally Mayberry highlights a number of trade books that have made a fantastic difference in the…
