The purpose of this study was to determine the effects of a socioscientific issues-based instructional model on secondary agricultural education students' content knowledge, scientific reasoning ability, argumentation skills, and views of the nature of science. This study utilized a pre-experimental, single group pretest-posttest design to assess…

This study measured the effect of completing a BalloonSat project on student attitude toward science. Seven categories of student attitudes toward science were measured using the Test of Science Relate Attitudes survey (TOSRA). The research anticipated that the BalloonSat project would have similar effects on student attitudes as found in robotics…

The researchers wanted to continue in their university's previous study of nature awareness and science achievement, specifically examining the effects of nature in the achievement of seventh-grade students. This further study offered valuable insight to the inconclusive findings of previous researchers of nature awareness and science achievement.…

This paper theorizes issues involved with conflicts between participation in on-line settings and real-world social commitments, such as has recently happened in schools with students using public discussion forums for classes. We problematize how real-world social commitments negatively affect participation in online learning environments…

For the past five years, teachers from four Houston-area school districts have joined together in a professional learning community (PLC) to improve their science teaching. Through the University of Houston-Clear Lake (UHCL) Regional Collaborative for Excellence in Science and Mathematics Teaching, the teachers strengthen content knowledge and…

Professional development for practicing science teachers has been a goal in education for the last two decades. Studies have shown that the quality of teacher instruction may be linked to teacher participation and involvement in professional development programs (Fishman, Marx, Best, & Tal, 2003). Furthermore, reflection during professional…

(Purpose) This article describes the use of tiered instruction, a specific form of differentiation, within the author's high school Physics classroom. A background and discussion on the nature of tiered instruction is also included. (Findings) Topics addressed in this paper include: (1) the necessity of differentiation within the classroom; (2)…

The topic of coupled oscillations is rich in physical content which is both interesting and complex. The study of the time evolution of coupled oscillator systems involves a mathematical formalization beyond the level of the upper secondary school student's competence. Here, we present an original approach, suitable even for secondary students, to…

In this activity, students use a model created from a coffee cup or cardstock cutout to explore the working principle of an atomic force microscope (AFM). Students manipulate a model of an AFM, using it to examine various objects to retrieve topographic data and then graph and interpret results. The students observe that movement of the AFM…

This study investigated the following question: To what extent and in what ways does constructing a video case of their own discussion-based teaching help interns reflect on their teaching? First, we discuss the notion of learning to learn from experience through reflection and analysis, why we chose classroom discussions as a site for studying…

A method is described for building a cost effective digital circuit capable of monitoring the solar radiation incident upon a remote solar cell. The circuit is built in two sections, the first, digitises the analogue voltage produced by the solar cell at a remote location and transmits the received signal to the second receiver circuit which…

The purpose of the research is to determine high school teachers' skill rate in designing exam questions in physics subject. The statistical population was all of physics exam shits for two semesters in one school year from which a sample of 364 exam shits was drawn using multistage cluster sampling. Two experts assessed the shits and by using…

Model-Based Inquiry (MBI) is an emergent instructional strategy that is gaining acceptance among science educators. This approach to learning realistically mirrors the work of scientists, who develop and test hypotheses to construct more sophisticated understandings of the natural world. This article details how the authors collaboratively taught…

This study aims to explore navigation patterns and preferred pages' characteristics of ten secondary school students searching the web for information about cloning. The students navigated the Web for as long as they wished in a context of minimum support of teaching staff. Their navigation patterns were analyzed using audit trail data software.…

Project-based science curricula can improve students' usable or meaningful understanding of the science content underlying a project. However, such curricula designed around "performances" wherein students design or make something do not always do this. We researched ways to design performance project-based science curricula (pPBSc) to better…
