Many students possess their own unique potential and "genius," but seem to base their worth on the status of grades instead of their connection to education itself. Antonio Salieri, for instance, created wonderful, emotionally binding music throughout his lifetime. Salieri however, never saw the beauty in his work because Mozart, a child…

American classrooms are increasingly heterogeneous linguistically. If all students are to engage in three-dimensional learning, how are educators making classroom assessments accessible and meaningful for emergent bilingual learners? There are few classroom assessment exemplars that embody the NGSS three-dimensional vision of the…

Learning centers can help teachers assess students' content knowledge without penalizing them for language barriers. With the increasing number of English language learners (ELLs) in classrooms, the emphasis on mastery of content and inclusion of all students in class discussions and activities will provide all students a chance for scientific…

Despite the burgeoning numbers of English language learners (ELLs) in our schools, many science teachers have little training in meeting their specialized needs. By the year 2010, it is estimated that 40% of K-12 classrooms in the United States will contain nonnative English speakers with varying levels of proficiency (Thomas and Collier 2002).…

Whole-class inquiry (WCI) assessments range from challenging, paper-and-pencil puzzles to lab-based problems that require students to apply their own gathered data to a new scenario; the latter might also require students to perform a lab with new parameters, or to answer a question using data from a previous lab. In this article, the authors…

Teachers know what a daunting job it can be to ensure that all students in a class learn effectively. In addition to the usual difficulties of gaining everyone's attention at once, instructors also run into the issue of preferred learning styles. In any classroom environment, the same topic is taught to multiple students, and each student may…

Teachers have many dilemmas when it comes to assessing a classroom of diverse students. Teachers need to find out what students really know while being fair to all students. They also need to learn how to alter assessments without watering down content. These challenges can be addressed by following five principles for equitable assessment. In…

One way of implementing project-based science (PBS) is to use problem-based learning (PBL), in which students formulate their own problems. These problems are often ill-structured, mirroring complex real-life problems where data are often messy and inclusive. In this article, the authors describe how they used PBL in a ninth-grade biology class in…

Supports the use of assessment probes to measure scientific achievement. Provides several examples and discusses the characteristics of effective probes. (DDR)

Presents information on a standards-based assessment for student laboratory work. Four criteria--planning and design, experimental execution, observation of changes, and interpretation and explanation--are presented along with standards for assessment of laboratory performance. Describes the benefits of teachers enunciating both criteria and…

Discusses the revamping of high school biology and chemistry curricula with the guiding principles of hands-on science and performance-based assessment. Includes goal identification, program design, and a discussion on measures of success. (DDR)

Describes an evaluation system used in a junior high school science course in which students evaluated their own achievement on a daily basis. (JR)

Science education has moved from the traditional lecture-and-demonstration model toward a student inquiry model. Inquiry activities allow students to discover many relationships of science for themselves. However beneficial this shift may be, former assessment methods used in the traditional model may no longer effectively determine student…

Describes an approach to teaching that involves the use of open-ended lab investigations and evaluates students using that same approach. Argues for the use of the rubric in evaluating student performance during experimentation. (DDR)

Most science teachers are amazed when grading tests and quizzes, often wondering how and why students have reached a conclusion, particularly when students fail to provide a detailed account of their logic. Ideally, a variety of assessments should be used to identify alternate student conceptions or gaps in understanding, particularly when…
