Incorporating forensic applications into chemical education serves as an effective strategy for engaging college students and equipping them with the skills necessary to become valuable in the workforce in relevant fields. For instance, learning how to extract controlled substances from biological specimens in a laboratory course is essential for…

Current laboratory-based practical classes are arranged so that all students can complete the required activities on time. With this system there is no incentive for students to optimize the time they spend in the laboratory or have awareness of whether they are conducting the activities in a timely manner. However, the acceptable timeframes for…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

The purpose of this study was to determine the effects of interactive multimedia simulations and virtual dissection software on depth of learning among students participating in biology and chemistry laboratory courses. By understanding more about how simulation and virtual dissection software changes depth of learning, educators will have the…

Even after repeated instruction, first year college chemistry students are often unable to apply stoichiometry knowledge to equilibrium and acid-base chemistry problems. The dynamic and interactive capabilities of online technology may facilitate stoichiometry instruction that promotes more meaningful learning. This study compares a…

The effectiveness of two different laboratory techniques is compared to teach students majoring in science in a general chemistry laboratory. The results demonstrated that student laboratory activities with computer-interface systems could improve student understanding.

The various equipments, procedure and hazards in constructing the device for inflating a methane balloon using a standard methane outlet in a laboratory are described. This device is fast, safe, inexpensive, and easy to use as compared to a hydrogen gas cylinder for inflating balloons.

Presents an experimental comparison of the efficacy of two neutron sources under conditions commonly used in laboratory experiments for demonstrating neutron activation of liquid samples. (Author)

Investigated was the effect of different types of laboratory reports on measured outcomes of the Chemical Education Materials Study (CHEMS) Chemistry. Compared were procedures using essay laboratory reports, mimeographed laboratory sheets prepared by the investigator and completed by the students, the laboratory manual for the course completed by…

Attainment of laboratory course objectives was compared for tenth and twelfth grade Israeli students using two chemistry curricula: An Experimental Chemistry Program for Secondary Schools (ECPSS) and the CHEM Study program. ECPSS students more often than non-ECPSS students, and ECPSS girls more often than boys felt they had achieved the…
