This research explores how explaining an anchoring phenomena and engaging students in investigations, as central designs of a model-based inquiry (MBI) unit, afforded or constrained the representation of scientific activity in the science classroom. This research is considered timely as recent standards documents and scholars in the field have…

Of great importance for achieving science education reform may be teachers' interest in science and enjoyment of science. This study explores the motivational qualities (rated for "interest," "fun," and "learning" value) of different levels of inquiry of hands-on class activities. The participants, 53 preservice teachers in two sections of a…

Within the field of science education, there remains little agreement as to the definition and characteristics of classroom inquiry. The emerging emphasis on scientific practices in science education reform discourse is underpinned by a need to better articulate the constituent elements of inquiry-based science. While a small number of…

This article presents exploratory research investigating the integration of music and a mathematics lesson as an intervention to promote preservice teachers' attitude and confidence and to extend their beliefs toward teaching mathematics integrated with music. Thirty students were randomly selected from 64 preservice teachers in a southern…

The study examined relationships among key domains of science instruction with English language learning (ELL) students based on teachers' perceptions of their classroom practices (i.e., what they think they do) and actual classroom practices (i.e., what they are observed doing). The four domains under investigation included: (1) teachers'…

Although popular media often provides negative images of mathematicians, we contend that mathematics classroom practices can also contribute to students' images of mathematicians. In this study, we examined eight mathematics teachers' framings of mathematicians in their classrooms. Here, we analyze classroom observations to explore some of the…

This study investigates defining characteristics among the process standards of the Principles and Standards for School Mathematics and the 5 "Es" from the National Science Education Standards and the Inquiry and the National Science Education Standards. These characteristics are used to demonstrate similarities and differences between the…

The context and nature of teacher efficacy beliefs provide a method upon which to explore science teachers' perceptions of their teaching effectiveness and student achievement as a function of ethnicity. Promotion of a more in-depth knowledge of science teaching efficacy requires cross-sectional and longitudinal investigations. In this study, a…

As the largest international study ever taken in history, the Trend in Mathematics and Science Study (TIMSS) has been held as a benchmark to measure U.S. student performance in the global context. In-depth analyses of the TIMSS project are conducted in this study to examine key issues of the comparative investigation: (1) item flaws in mathematics…

The purpose of this study was to explore the effect of providing preservice teachers the opportunity to collect real data in a science methods inquiry investigation and using the data, design data displays in their mathematics methods course. The research questions focused on how preservice teachers' understandings of data displays, research…

This article explores the use of problem posing in the calculus classroom using investigative projects. Specially, four examples of student work are examined, each one differing in originality of problem posed. By allowing students to explore actual questions that they have about calculus, coming from their own work or class discussion, or…

Field investigations are not characterized by randomized and manipulated control group experiments; however, most school science and high-stakes tests recognize only this paradigm of investigation. Scientists in astronomy, genetics, field biology, oceanography, geology, and meteorology routinely select naturally occurring events and conditions and…

Students calculate the speed of cars moving on a highway as a lab activity. Directions for teachers, objectives, goals, grade level (7-12), materials and procedures are detailed. (JP)

Describes the method for verifying the accuracy of the shadow-stick method of determining east-west line with the shadow of sun. Description is also included for determining South by using a watch-shadow method. (Author/PS)

Using syringes, a hydraulic press was constructed and mechanical advantage and efficiency were calculated. (CP)
