The study investigated the effects of graphic organizer (GO) and experiential learning (EL) with feedback on the mean achievement and students' critical thinking in Jos North Local Government Area of the Plateau State of Nigeria. A pre-test post-test quasi-experimental design was used. A sample of 75 students was drawn from the population of 1950…

Students learned about electrical circuits in an arcade-type game consisting of 10 levels. For example, in one level students saw two circuits consisting of various batteries and resistors connected in series or parallel, and had to indicate which one had a higher rate of moving current. On levels 1-9, all students received a correct tone and had…

This is the report of a qualitative emergent-design study of 2 different Web-enhanced science methods courses for preservice elementary teachers in which an experiential learning strategy, labeled "using yourself as a learning laboratory," was implemented. Emergent grounded theory indicated this strategy, when embedded in a course organized as an…

Describes a camping experience and its activities created for girls entering 6th grade who wanted to learn science and explore science-related fields. Indicates that the camping experience for girls promoted positive attitudes toward science learning. (KHR)

Cell death is an essential factor in many biological processes including development. Discusses two types of cell death: (1) necrosis (induced by sodium azide); and (2) apoptosis (induced by sodium chromate). Illustrates key features that differ between these two types of cells death including loss of membrane integrity and internucleosomal DNA…

Presents cooperative classroom projects using science as the initial basis for the study of bears. These projects may also involve other areas of the curriculum such as mathematics, art, and music. "Black Bear" activities include following a park ranger to study our National Parks and researching and building a full-sized brown bear…

Provides activities that explore the concept of solubility using correction fluid. Topics include oil versus water solubility and whole milk versus fat-free milk. (DDR)

Describes some inquiry-based labs in which students identify starch in popped popcorn, then determine whether starch is present in the kernels prior to them being cooked. Students distinguish monocot and dicot stems as well as determining whether boiling kills tissues in seeds that have been soaked in water. (DDR)

Discusses the teaching method of students studying a topic, then explaining the meaning of the concept to each other in their own words using examples from their everyday lives. The instructor acts as a coordinator, mediator, and a resource person. Concludes with the disadvantages of this interactive learning technique on a habitat tour, among…

Presents an activity in which students investigate the chemistry behind color-changing markers. Includes the objectives, materials, procedures, and follow-up for the activities. (DDR)

Presents an activity that demonstrates how a traditional activity can generate questions not typically raised in a conventional course. In the context of astrobiology, students can connect to an intriguing endeavor, the search for extraterrestrial life. (DDR)

Describes how a jigsaw cooperative learning structure divides lab work in a constructive, efficient way and provides a mechanism for sharing information. Pre-lab lectures are replaced with focused student discussions about the lab exercises. Students become more involved with the lab exercises, take responsibility for their own learning, and are…

Presents activities that integrate physics, earth science, and health. Students explore their own sensible temperature focusing on the physical processes of heat transfer. (DDR)

Presents information about the chemistry of color-changing markers. Discusses the importance of acid-base reactions and oxidation-reduction chemistry. (DDR)
