Automated Titration

This paper proposes a learning environment in which manual operations of school chemistry laboratory experiments, such as titration and aliquoting, are automated by means of computer controlled devices. The educational study focuses on characteristics of learning in the automated laboratory environment. Pilot teaching indicated that using automation devices significantly reduces the performance time of titration laboratory work. The students also noted that automated titration experiments are more simple and accurate. Therefore, automation of manual operations in laboratory practice has been found to provide a very positive learning environment.

The undergraduate chemistry laboratory is an ideal place for meaningful learning to occur, and the laboratory work is considered as an integral part of most chemistry courses; however, a significant proportion of laboratory experiments remain highly prescriptive and fail to challenge undergraduate students. This study investigated the chemistry laboratory environment among 170 undergraduate students at a private university in Beirut, Lebanon. Data were collected using the Chemistry Laboratory Environment Inventory with its both versions: Actual Chemistry Laboratory Environment Inventory and Preferred Chemistry Laboratory Environment Inventory. The findings of this study showed that the students prefer a chemistry learning environment with greater levels of integration and material environment, but less level of open-endedness. Suggestions for improving chemistry laboratory learning environments are provided. Keywords: Chemistry, laboratory, undergraduate courses, learning environment.

To teach the net generation in today’s classrooms, it calls for innovativeteaching and learning strategies that are engaging so as to sustain learners’interest in learning. This paper describes how Singapore has successfullylaunched ICT initiatives in schools and expounds the use of the MixedMode Delivery (MMD) pedagogical model in ICT-Rich classroomsin Singapore educational context. This paper discusses how ICT isharnessed so as to support the MMD model where student teachersare empowered with a wide repertoire of strategies and tools to createa more positive learning environment. The paper concluded with theremark on the importance of the MMD as a viable pedagogical modelfor sustaining interest of learners in a high-tech world.

As our world becomes more technologically advanced, research suggests that technology-rich learning environments support students as well. Mobile Virtual Laboratories can be used to replicate physical laboratories and augment the incorporation of technology inside science classrooms in an attempt to provide students with laboratory experiences that would not otherwise be available in high school settings. This study measured the effectiveness of mobile virtual laboratory as innovative strategy to improve learners’ achievement, attitudes, and learning  environment in teaching chemistry. The study utilized one-group pretest–posttest design. The innovative strategy is calculated using this design by measuring the difference between the pretest and posttest scores, attitudes and learning  environment in teaching chemistry. The study revealed that the utilization of the innovative strategy mobile virtual laboratory in teaching chemistry showed that learners have a strong positive attitude. More so, the learners have a strong positive learning environment when exposed to the innovative strategy mobile virtual laboratory based on the six domain of learning environment in teaching chemistry. As shown by the significantly higher mean in the posttest than in the pretest, the innovative strategy mobile virtual laboratory had a positive impact on the learners' achievement. Consequently, the learners exposed to the mobile virtual laboratory in teaching chemistry are significantly differ in pretest and posttest results. The findings of this study have the potential to reassure educational professionals, contribute to the body of research within the field of chemistry achievement, attitudes, and learning  environment, and encourage further research into the efficacy of mobile virtual laboratories as a teaching tool.
