move teaching away from covering many isolated facts to a focus on a smaller number of disciplinary core ideas (DCIs) and crosscutting concepts that can be used to explain phenomena and solve problems by engaging in science and engineering practices. The NGSS present standards as knowledge-inuse by expressing them as performance expectations (PEs) that integrate all three dimensions from the Framework for K-12 Science Education. This integration of core ideas, practices, and crosscutting concepts is referred to as three-dimensional learning (NRC in Division of Behavioral and Social Sciences and Education. The National Academies Press, Washington, 2014). PEs state what students can be assessed on at the end of grade level for K-5 and at the end of grade band for 6-8 and 9-12. PEs do not specify how instruction should be developed nor do they serve as objectives for individual lessons. To support students in developing proficiency in the PEs, the elements of the DCIs will need to be blended with various practices and crosscutting concepts. In this paper, we examine how to design instruction to support students in meeting a cluster or ''bundle'' of PEs and how to blend the three dimensions to develop lesson level PEs that can be used for guiding instruction.

We re-conceptualized the meaning of scientific literacy and developed an instrument, which we call the Global Scientific Literacy Questionnaire (GSLQ) based on a new conceptual framework for scientific literacy in the twenty-first century. We identified five dimensions, each with key elements. The five dimensions are (1) content knowledge (core ideas of science), (2) habits of mind (science practices), (3) character and values, (4) science as human endeavor, and (5) metacognition and self-direction. In this study, we attempted to diagnose the extent to which South Korean secondary students perceive themselves as global citizens having such capabilities using GSLQ with 3,202 students (7th-12th grades). Validity and reliability were examined using various statistical techniques including the Cronbach's α coefficient, exploratory factor analysis, and confirmatory factor analysis. The use and value of the instrument were discussed by examining the Korean secondary students' overall scientific literacy as well as their views on each dimension across gender and grade levels. We recommend that teachers and researchers use the GSLQ to assess students' global scientific literacy and provide comments on its usefulness as a research tool and the practical use of its inventory of items.
