This experiment was designed to help students improve the critical thinking skills that are required to analyze and discuss the results of an organic chemistry experiment in an effective manner. The initial objective indicated in the prelab handout for this puzzle experiment was the synthesis of methyl 4-bromobenzoate using the Fischer…

An important learning goal of a molecular biology curriculum is the attainment of a certain competence level in experimental design. Currently, undergraduate students are confronted with experimental approaches in textbooks, lectures and laboratory courses. However, most students do not reach a satisfactory level of competence in the designing of…

Attitudinal data tested hypotheses that students have more positive attitudes toward science when teachers regularly emphasize hands-on laboratory activities and when students more frequently experience higher levels of experimentation or inquiry. The first predicted that students would have more positive attitudes toward science in classrooms…

Hands-on science typically uses physical materials to give students first-hand experience in scientific methodologies, but the recent availability of virtual laboratories raises an important question about whether what students' hands are on matters to their learning. The overall findings of two articles that employed simple comparisons of…

This book contains hands-on ocean-related laboratory activities. Major chapter hearings are: (1) "Water Experiments" (dealing with the physical nature of water and listing 10 activities); (2) "Ocean-Going Vessels" (studying the principles of boats, with three experiments); (3) "Experiments Using Shells" (containing four activities); (4) "Sand…

This study compared the effects of cooperative learning groups to traditional instruction in remediating students' misconceptions about temperature. Students from grades 3, 4, and 5 in two rural elementary schools participated in the study. Students completed a pretest, a cognitive conflict laboratory activity and a posttest that measured…

This study explored the impact of cooperative learning in a college level laboratory science course by comparing classes taught by a conventional lab-lecture technique. Students in a basic science skills course for preservice elementary teachers participated over a 14-week period. Instruments used were the Science Attitude Survey, Test of Logical…

This second volume in the Topics for Teachers series provides a wide range of activities designed to be both useful for teachers and informative for students. The investigations contained in this document are representative of some of the embodiments of important mathematical principles in the physical world. The activities included were chosen…

This technical report is in three parts. Part I is a conceptual treatment of communication in which the human being is viewed as a goal-attainment system. The goal-attainment problem is defined as a discrepancy between the current state of the system and a specified goal state. Several forms of the communicative relationship are outlined. Part II…

Introduces two hands-on experiences, related to rotational motion and moment of inertia. Discusses the experimental procedures and provides figure of apparatus. (YP)

Describes a circuit by which capacitance and the dielectric constant can be measured. Shows the circuit diagram and the method to calculate these constants. (YP)

Introduces some ideas on teaching scaleup in chemical engineering. Discusses the instructional modes and the general and specific topics. Provides two examples of an experiment with equipment and safety issues. Shows the list of actual individual and team projects in an appendix. (YP)

Discusses role of computer simulation in complementing and extending conventional components of undergraduate engineering education process in United Kingdom universities and polytechnics. Aspects of computer-based learning are reviewed (laboratory simulation, lecture and tutorial support, inservice teacher education) with reference to programs in…

This report is one of a series of reports from a research project that focuses on the evaluation of laboratory work in secondary schools. The study focuses on 12 different laboratory tasks from the biology and chemistry courses of the Finnish comprehensive school. Secondary students (N=212) were observed during laboratory sessions and analysis of…

This lesson explores the group of buildings in West Orange, New Jersey, built in 1887, that formed the core of Thomas Edison's research and development complex. They consisted of chemistry, physics, and metallurgy laboratories; machine shop; pattern shop; research library; and rooms for experiments. The lesson explains that the prototypes (ideas…
