- As a Laboratory Manager the theory that I would like to use or apply is Scientific Management . From the theory ’s name itself , it uses science to work and this theory does time and motion studies to study how much time every single little task should take and how many motions every single task should take and we can speed things up and come up with “ one right way ” .
Performance Statement Examples. Shows up to work on time, and follows instructions, policies, and procedures. Meets productivity standards, deadlines, and work schedules.
Ensures staff have the skills and resources to get things done. Provides staff with coaching, training, and opportunities for growth to improve their skills. Gives staff ongoing, constructive feedback on their performance and progress in light of expectations and goals. Holds timely discussions and performance reviews .
Displays a positive attitude about the work to be done, co-workers, customers, management, and employer policies. Addresses issues in an open, constructive, professional manner, and persuades others to approach issues in the same manner. Leads by example and sets standards for professional behavior.
Definition. Aligns the direction, products, services, and performance of a business line with the rest of the organization. Performance Statement Examples. Seeks to understand other programs in the department, including their services, deliverables, and measures.
Laboratory experiences are more likely to be effective when they focus students more on discussing the activities they have done during their laboratory experiences and reflecting on the meaning they can make from them, than on the laboratory activities themselves. Crucially, the focus of laboratory experiences and the surrounding instructional activities should not simply be on confirming presented ideas, but on developing explanations to make sense of patterns of data. Teaching strategies that encourage students to articulate their hypotheses about phenomena prior to experimentation and to then reflect on their ideas after experimentation are demonstrably more successful at supporting student attainment of the goals of mastery of subject matter, developing scientific reasoning, and increasing interest in science and science learning. At the same time, opportunities for ongoing discussion and reflection could potentially support students in developing teamwork skills.
1. There is a larger body of research on how students learn science that is not considered in depth here because the committee’s focus is science learning through laboratory experiences.
The science learning goals of laboratory experiences include enhancing mastery of science subject matter, developing scientific reasoning abilities, increasing understanding of the complexity and ambiguity of empirical work, developing practical skills, increasing understanding of the nature of science, cultivating interest in science and science learning, and improving teamwork abilities.
A common theme in reviews of laboratory practice in the United States is that laboratory experiences are presented to students as isolated events, unconnected with other aspects of classroom work. In contrast, integrated instructional units embed laboratory experiences with other activities that build on the laboratory experiences and push students to reflect on and better understand these experiences. The way a particular laboratory experience is integrated into a flow of activities should be guided by the goals of the overall sequence of instruction and of the particular laboratory experience.
In laboratory experiences, students may learn to use the tools and conventions of science. For example, they may develop skills in using scientific equipment correctly and safely, making observations, taking measurements, and carrying out well-defined scientific procedures. Understanding of the nature of science.
These two aspects of science are reflected in the goals of laboratory experiences, which include mastery of subject matter (accepted scientific ideas about phenomena) and several goals related to the processes of science (understanding the complexity of empirical work, development of scientific reasoning). Research on student thinking about science ...
The ThinkerTools instructional unit is a sequence of laboratory experiences and other learning activities that, in its initial version, yielded substantial gains in students’ understanding of Newton’s laws of motion (White, 1993). Building on these positive results, ThinkerTools was expanded to focus not only on mastery of these laws of motion but also on scientific reasoning and understanding of the nature of science (White and Frederiksen, 1998). In the 10-week unit, students were guided to reflect on their own thinking and learning while they carry out a series of investigations. The integrated instructional unit was designed to help them learn about science processes as well as about the subject of force and motion. The instructional unit supports students as they formulate hypotheses, conduct empirical investigations, work with conceptually analogous computer simulations, and refine a conceptual model for the phenomena. Across the series of investigations, the integrated instructional unit introduces increasingly complex concepts. Formative assessments are integrated throughout the instructional sequence in ways that allow students to self-assess and reflect on core aspects of inquiry and epistemological dimensions of learning.
