Meaningful learning requires the integration of cognitive and affective learning with the psychomotor, i.e., hands-on learning. The undergraduate chemistry laboratory is an ideal place for meaningful learning to occur. However, accurately characterizing students' affective experiences in the chemistry laboratory can be a very difficult task. While…

Despite many research studies showing the effectiveness of teacher application of child-centered learning in different educational settings, few studies have focused on teaching and learning activities in Pre-Schools. This research investigates the effect of child centered methods on teaching and learning of science activities in preschools in…

Through a non-experimental descriptive and comparative mixed-methods approach, this study investigated the experiences of sixth grade earth science students with groundwater physical models through an extended SE learning cycle format. The data collection was based on a series of quantitative and qualitative research tools intended to investigate…

Helping students better understand how scientists reason and argue to draw scientific conclusions has long been viewed as a critical component of scientific literacy, thus remains a central goal of science instruction. However, differences of opinion persist regarding the nature of scientific reasoning, argumentation, and discovery. Accordingly,…

In this paper we present Geodromo, a prototype of an educational multimedia system, part of the Portuguese "Ciencia Viva" (Live Science) educational program, which is aimed at young people and designed with innovative characteristics. The project is based on a robotic multimedia simulator and an online puzzle game aimed at the…

The impulse to investigate the natural world is deeply rooted in our earliest childhood experiences. This notion has long guided researchers to uncover the cognitive mechanisms underlying the development of scientific reasoning in children. Until recently, however, research in cognitive development and education followed largely independent…

A notebook is perhaps the single most important piece of equipment a naturalist takes into the field. But notebooks are not only for use by field scientists: They are also excellent tools for helping students record observations outdoors, develop communication skills, and mirror the work of real scientists. They may contain observations and…

Presents activities that utilize balloons to encourage students to explore questions related to scientific concepts. Concepts explored include light, heat, charged ions, polarization, and the sense of smell. (MDH)

Using a unit on earthworms, this article shows how science and language arts can be successfully integrated in a middle school classroom through hands-on observation, interviewing, and writing exercises. The integration process engages students, uses class time more efficiently, encourages dialog, and improves outcomes and appreciation of the…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

Presents an activity in which students develop science process skills by making inferences as to the contents of a "mystery" box from observations based on their sensory perceptions. Provides instructions for implementing and extending the activity. (MDH)
