Move Over Galileo, It's Science 2.0 :: University Communications Newsdesk, University o... - 0 views

  •  
    In a provocative article in this week's Science Magazine, the University of Maryland's Ben Shneiderman, one of the world's leading researchers and innovators in human-computer interaction, says it's time for the laboratory research that has defined science for the last 400 years to make room for a revolutionary new method of scientific discovery. He calls it Science 2.0., and it combines the hypothesis based inquiry of laboratory science with the methods of social science research to understand and improve the use of new human networks made possible by today's digital connectivity. Through Science 2.0, the societal potential of such networks can be realized for applications ranging from homeland security to medical care to the environment. Recently honored by the International Journal of Human-Computer Interaction for his leadership in bringing scientific methods to the study of human use of computers, Shneiderman points to the effect that the World Wide Web and cell phones have had on building human collaborations and influencing society.

    Our holistic learning approach continues in different forms, so, today lemonade making activity organized in The Ummed School in which students learned how 2-3 substances are mixed and a totally new substance is formed. This type of practical learning approach helps a lot in developing creativity and forming a thought process. Lemonade is the drink of choice for countless people-and now you can use it to teach your little ones the scientific method! This fun science activity for kids allows children to make their own lemonade while following directions, making a hypothesis, and collecting data through observation. Activity Instructions Cut a lemon into four pieces and throw away all of the seeds. Put a piece of lemon in a Ziploc bag, one for each child and one for yourself. Help your children measure and add a half a cup of water and a teaspoon of sugar to their bags. When all of the ingredients are added, zip the bags. Help your child squeeze the lemon into the bag and shake it up to mix the contents. As you are shaking it ask your kids to predict what will happen to the ingredients. Have them talk about the changes they are seeing within the bag and how they think the lemonade will taste. After 30 seconds, stop mixing and add a couple of ice cubes to each bag. Hand your little ones a straw and enjoy! The outcome of Activity This fun science activity for kids will teach your little ones how to follow the scientific method. They will listen to your instructions, predict the outcome of the activity, and make observations throughout. Additionally, they will create a delicious drink that they can enjoy!

    Islam elevates the acquisition of new knowledge. Modern science was first developed in the Muslim world, all the wealth of knowledge in the world has actually emanated from Muslim civilization, and what people call "the scientific method", is actually "the Islamic method. Muslims started the concept of learning and established islamic schools where children could learn.

Critical Issue: Using Technology to Improve Student Achievement - 0 views

shared by anonymous on 23 Feb 10 - Cached
  • Technologies available in classrooms today range from simple tool-based applications (such as word processors) to online repositories of scientific data and primary historical documents, to handheld computers, closed-circuit television channels, and two-way distance learning classrooms. Even the cell phones that many students now carry with them can be used to learn (Prensky, 2005).
  • Bruce and Levin (1997), for example, look at ways in which the tools, techniques, and applications of technology can support integrated, inquiry-based learning to "engage children in exploring, thinking, reading, writing, researching, inventing, problem-solving, and experiencing the world." They developed the idea of technology as media with four different focuses: media for inquiry (such as data modeling, spreadsheets, access to online databases, access to online observatories and microscopes, and hypertext), media for communication (such as word processing, e-mail, synchronous conferencing, graphics software, simulations, and tutorials), media for construction (such as robotics, computer-aided design, and control systems), and media for expression (such as interactive video, animation software, and music composition). In a review of existing evidence of technology's impact on learning, Marshall (2002) found strong evidence that educational technology "complements what a great teacher does naturally," extending their reach and broadening their students' experience beyond the classroom. "With ever-expanding content and technology choices, from video to multimedia to the Internet," Marshall suggests "there's an unprecedented need to understand the recipe for success, which involves the learner, the teacher, the content, and the environment in which technology is used."
  • In examining large-scale state and national studies, as well as some innovative smaller studies on newer educational technologies, Schacter (1999) found that students with access to any of a number of technologies (such as computer assisted instruction, integrated learning systems, simulations and software that teaches higher order thinking, collaborative networked technologies, or design and programming technologies) show positive gains in achievement on researcher constructed tests, standardized tests, and national tests.

  • Boster, Meyer, Roberto, & Inge (2002) examined the integration of standards-based video clips into lessons developed by classroom teachers and found increases student achievement. The study of more than 1,400 elementary and middle school students in three Virginia school districts showed an average increase in learning for students exposed to the video clip application compared to students who received traditional instruction alone.
  • Wenglinsky (1998) noted that for fourth- and eighth-graders technology has "positive benefits" on achievement as measured in NAEP's mathematics test. Interestingly, Wenglinsky found that using computers to teach low order thinking skills, such as drill and practice, had a negative impact on academic achievement, while using computers to solve simulations saw their students' math scores increase significantly. Hiebert (1999) raised a similar point. When students over-practice procedures before they understand them, they have more difficulty making sense of them later; however, they can learn new concepts and skills while they are solving problems. In a study that examined relationship between computer use and students' science achievement based on data from a standardized assessment, Papanastasiou, Zemblyas, & Vrasidas (2003) found it is not the computer use itself that has a positive or negative effect on achievement of students, but the way in which computers are used.
  • Another factor influencing the impact of technology on student achievement is that changes in classroom technologies correlate to changes in other educational factors as well. Originally the determination of student achievement was based on traditional methods of social scientific investigation: it asked whether there was a specific, causal relationship between one thing—technology—and another—student achievement. Because schools are complex social environments, however, it is impossible to change just one thing at a time (Glennan & Melmed, 1996; Hawkins, Panush, & Spielvogel, 1996; Newman, 1990). If a new technology is introduced into a classroom, other things also change. For example, teachers' perceptions of their students' capabilities can shift dramatically when technology is integrated into the classroom (Honey, Chang, Light, Moeller, in press). Also, teachers frequently find themselves acting more as coaches and less as lecturers (Henriquez & Riconscente, 1998). Another example is that use of technology tends to foster collaboration among students, which in turn may have a positive effect on student achievement (Tinzmann, 1998). Because the technology becomes part of a complex network of changes, its impact cannot be reduced to a simple cause-and-effect model that would provide a definitive answer to how it has improved student achievement.
  • When new technologies are adopted, learning how to use the technology may take precedence over learning through the technology. "The technology learning curve tends to eclipse content learning temporarily; both kids and teachers seem to orient to technology until they become comfortable," note Goldman, Cole, and Syer (1999). Effective content integration takes time, and new technologies may have glitches. As a result, "teachers' first technology projects generate excitement but often little content learning. Often it takes a few years until teachers can use technology effectively in core subject areas" (Goldman, Cole, & Syer, 1999). Educators may find impediments to evaluating the impact of technology. Such impediments include lack of measures to assess higher-order thinking skills, difficulty in separating technology from the entire instructional process, and the outdating of technologies used by the school. To address these impediments, educators may need to develop new strategies for student assessment, ensure that all aspects of the instructional process—including technology, instructional design, content, teaching strategies, and classroom environment—are conducive to student learning, and conduct ongoing evaluation studies to determine the effectiveness of learning with technology (Kosakowski, 1998).
