The Wooden Periodic Table Table - 1 views

  • This website documents, in great depth, a large collection of chemical elements and examples of their applications, common and uncommon. Click any element tile above and you will find probably more than you ever wanted to know about that element. All these samples (well, at least the ones that fit) are stored in a wooden periodic table, by which I mean a physical table you can actually sit at, in my office at Wolfram Research. I decided to build this table by accident in early 2002, as a result of a misunderstanding while reading Uncle Tungsten by Oliver Sacks. I won't bore you with the details here (see the Complete Pictorial History of the Wooden Periodic Table Table), but once it was finished I felt obligated to start finding elements to go in it (because under the name of each element in my table there is a sample area). Then I started building a website to document all my samples, and that's when things really got out of hand. A few months later my little table won the 2002 Ig Nobel Prize in Chemistry, clearly the highest honor for which it is eligible. Sensing an audience, I began to take the website more seriously, which led to my being asked to write a monthly column for Popular Science magazine, which I've now been doing continuously since the July 2003 issue. Later I formed a most satisfying partnership with Max Whitby building high-end museum displays, selling element samples and sets, and filming video demonstrations of the chemical properties of the elements. This website now contains the largest, most complete library of stock photographs of the elements and their applications available anywhere, as well as a large and growing collection of 3D images documenting hundreds of samples rotated through 360 degrees. Try clicking on some elements in the table above: I think you'll be surprised what's lurking behind those little tiles. And if you like the pictures, you'll love the poster! After years of photography and months of assembling images, I published a photographic periodic table poster based on my collection:

  • In the second phase, 13 of the 22 respondents to the first phase were sent follow-up questions to elicit their perspectives as to whether the use of VoiceThread satisfied Chickering and Gamson's (1987) Seven Principles for Good Practice in Undergraduate Education.
  • Results Out of a total of 61 students in two online sections of the business policy course, 22 students – 14 females and eight males – took part in the exam review and VoiceThread survey (i.e., the first phase of the study). The participants were graduating seniors, and as part of the course, they had participated in weekly discussion board activities within the University’s LMS, Blackboard. None of them had used VoiceThread prior to their involvement in the study. The survey results are presented in Tables 1, 2, and 3. Table 1. Survey responses – "yes/no" items (N = 22)

Would you like to use VoiceThread for future exam reviews and discussion of chapter concepts? 14 8 "Yes. [It is] More interactive, [and involves] not just reading text, but actually listening, and picking up information that way." "Yes. By then I will know how to use the microphone." "No. [It] Take[s] less time to read answers on Blackboard's discussion board as opposed to listening to people's answers on VoiceThread. It was difficult to read the small text." (This student liked participating in the exam review on VoiceThread for the extra credit, and she would do it again if extra credit were given.) "No. I won't be able to use it with my other devices such as my iPad and iPhone." "No. It's easier to read the review questions and find the answers in the book." 4. Would you like to use VoiceThread to make a presentation for a course in the future? 14 8 "Yes. Sure! That would probably work out pretty well!" "Not really! Not unless I have to." 5.

"Seems like a great tool we can use." Comments expressing reservations (n = 4) "I think it was very easy to figure out. My hesitation about using in the future for a course to do a presentation or recommending my peers to use it is that I don't really know much about it so that is why I responded no to those questions. I don't know how to add graphics and things of that nature like on PowerPoint." "VoiceThread is easy to register [on]. However, I'm not too sure about making a presentation." "I think it's a good form of technology. It's not my first choice of communication though. Plus if you're typing your answer the font is super small, not sure if I can change this setting." "[There needs to be a] bigger text box" Unfavorable comments (n = 2) "I do not like the interface of the VoiceThread ... [The interface] makes it hard to use on anything besides a computer." One student found it slightly difficult to "figure out how to answer the questions or how to comment on others' answers."

Online Teaching Effectiveness: A Tale of Two Instructors | Gorsky | The International R... - 0 views

  • We propose, as have others (i.e., Shea, Pickett, & Pelz, 2003), that the community of inquiry model (Garrison, Anderson, & Archer, 2000) reflects the principles of good practice in undergraduate education and can accurately quantify them.

  • Social presence is the perceived presence of others in mediated communication (Rourke, Garrison, & Archer, 1999), which Garrison et al. (2000) contend supports both cognitive and teaching presence through its ability to instigate, to sustain, and to support interaction. It had its genesis in the work of John Dewey and is consistent with all theoretical approaches to learning in higher education.
  • Teaching presence is defined as “the design, facilitation and direction of cognitive and social processes for the purpose of realizing [students’] personally meaningful and educationally worthwhile outcomes” (Anderson et al., 2001, p.5). Vygotsky’s (1978) scaffolding analogies illustrate an assistive role for teachers in providing instructional support to students from their position of greater content knowledge. Although many authors recommend a “guide on the side” approach to moderating student discussions, a key feature of this social cognition model is the adult, the expert, or the more skilled peer who scaffolds a novice’s learning
  • Shea, Pickett, & Pelz , 2004
  • Each category of a tutor’s presence is vital to learning and to the establishment of the learning community; tutors' behavior must be such that they are seen to be “posting regularly, responding in a timely manner and modeling good online communication and interaction” (Palloff & Pratt, 2003, p.118). Without an instructor’s explicit guidance and “teaching presence,” students were found to engage primarily in “serial monologues” (Pawan et al., 2003). Baker (2004) discovered that “instructor immediacy, i.e., teaching presence (Rourke et al., 1999), was a more reliable predictor of effective cognitive learning than whether students felt close to each other. Studies have demonstrated that instructor participation in threaded discussion is critical to the development of social presence (Shea, Li, Swan, & Pickett, 2005; Swan & Shih, 2005) and sometimes not fully appreciated by online faculty (Liu, Bonk, Magjuka, Lee, & Su, 2005). Shea, Li, and Pickett (2006) proposed that teaching presence – viewed as the core role of the online instructor – is a promising mechanism for developing learning community in online environments.
  • students ranked instructor modeling as the most important element in building online community, while instructors ranked it fourth.
  • Shea (2006), who completed an extensive study of teaching presence and online learning, concluded that two categories (“design” and “directed facilitation”) sufficed to define the construct.
  • Kalman, Ravid, Raban, and Rafaeli (2006) argued that interactivity is an essential characteristic of effective online communication and plays an important role in keeping message threads and their authors together. Interactive communication (online as well as in traditional settings) is engaging, and loss of interactivity results in a breakdown of the communicative process.
  • Research indicates the existence of a relationship between learners’ perceptions of social presence and their motivation for participation in online discussions (Weaver & Albion, 2005).
  • Northrup (2002) found that online learners felt it was important for instructors to promote collaboration and conversation. When interactive activities are carefully planned, they lead not only to greater learning but also to enhanced motivation (Berge 1999; Northrup, 2002).
  • Researchers have suggested that timing of messages can serve as a proxy for a sense of social presence (Blanchard, 2004), as an indication of attentiveness (Walther & Bunz, 2005) or respect (Bargh & McKenna, 2004), and as a clue to the sociability of a community (Maloney-Krichmar & Preece, 2005). As such, the frequency of messages may serve as a signal for how engaged participants are with the community.
    • Irene Watts-Politza
       
      Agreed.
  • Eom found that the most significant factors for increasing student satisfaction with online classes are paying attention to students and responding to their concerns.
  • The highly esteemed instructor was especially active from semester midpoint to semester end; she more than doubled her active participation in both teaching presence (especially discourse and instruction) and social presence (all three categories).
  • the lack of specific, progressively structured inquiry tasks and/or the lack of facilitation skills (teaching presence/facilitating discourse) may have contributed to the relatively limited occurrences of cognitive presence.
  • something else accounted for the extreme satisfaction and dissatisfaction experienced by students in the two forums. The something else may be the two exceptional events that occurred during the third month: The instructor held in low esteem became nearly dysfunctional, while the highly esteemed instructor exhibited very high teacher presence and social presence (see Table 3 and 4).
  • Shea, Pickett, and Pelt (2003) found that students’ perceived teacher presence also correlates with perceived learning as well as with students’ satisfaction with the forum. This correlation points to the tentative conclusion that teaching presence affords learning by setting a convenient climate.
  • we suggest that students’ perceived learning in course forums has a significant impact on their participation
  • the table is suggestive of the eventual possibility of having an “objective” tool for evaluating the quality of a given forum.
  • (Anderson et al., 2001).
  • Teaching effectiveness may be defined as how an instructor can best direct, facilitate, and support students toward certain academic ends, such as achievement and satisfaction. Teaching effectiveness has been investigated extensively in traditional classrooms for more than seven decades (for a meta-analysis of empirical studies from 1995-2004, see Seidel & Shavelson, 2007). Over the past five years, research has become directed toward teaching effectiveness in online or virtual classes. As a preface to our study, we discuss findings and conclusions concerning teaching effectiveness in traditional classrooms.

I am a visual person and I know that my classroom also has visual learners. I can describe things in text or verbally until I am blue in the face, but SEEING these things in photos or on videos is what sets it apart and commits them to memory. Above is a picture of sodium in its natural state as a metal...I try to emphasize this to my students since often the examples we use in class is sodium chloride, or table salt. A silver metal bonded to a noxious green gas combines to make table salt. That's a hard thing to imagine for anyone, so I show them using this resource. I LOVE webelements.

Online Teaching Challenge: Creating an Emotional Connection to Learning, part 1 - Facul... - 0 views

  • Browse Topics Faculty Focus Articles September 28, 2010 Online Teaching Challenge: Creating an Emotional Connection to Learning, part 1 By: Rob Kelly in Online Education Add Comment Learning research indicates that people learn better in the presence of some emotional connection—to the content or to other people. Creating this emotional connection is particularly challenging in the online classroom, where most communication is asynchronous and lacks many of the emotional cues of the face-to-face environment. Nevertheless, it is possible to do, with a learner-centered approach to teaching and a mastery of the technology that supports it, says Rick Van Sant, associate professor of education at Ferris State University. “One of the things we know about learning is that learning with emotion is a far deeper experience than learning without emotion,” Van Sant says. Citing recent research (see reference below), Van Sant notes that a little bit of stress and the corresponding release of cortisol makes “neural connections grow thicker, stronger, faster.” However, too much cortisol degrades memory performance. Creating an emotionally stimulating environment is something good face-to-face instructors do intuitively. “We live and thrive on the positive feedback from students. Students shape our behavior all the time. When technology is mediating between the learners and me, I lose the capacity to read my audience, engage my audience, and alter my style and cadence. I have no capacity on that kind of intuitive level [in the online classroom]. It all has to be intentional and cognitive,” Van Sant says.

EBSCOhost: Creating Effective Student Engagement in Online Courses: What Do Students F... - 0 views

  •  
    While this paper set out to discover what activities and/or interaction channels might be expected to lead to more highly engaged students, what it found was a bit different. After first creating a scale to measure online student engagement, and then surveying 186 students from six campuses in the Midwest, the results indicate that there is no particular activity that will automatically help students to be more engaged in online classes. However, the results also suggest that multiple communication channels may be related to higher engagement and that student-student and instructor-student communication are clearly strongly correlated with higher student engagement with the course, in general. Thus, advice for online instructors is still to use active learning but to be sure to incorporate meaningful and multiple ways of interacting with students and encouraging/requiring students to interact with each other.

They desire their time off more than extra pay or promotions and have little fear of changing jobs. In turn, they do not expect employer loyalty. This generation is shaped by a culture of instant results. They are comfortable with multitasking, are motivated to get the job done, value efficiency and directness, expect immediate responses, and look at education as a means to an end

ECRP. Vol 5 No 2. The Role of Child Development and Social Interaction in the Selection... - 0 views

  • A closer look might provide insight into how this experience will assist in Rachel's development: Positive emotions are created from the established lap reading routine that generates an intimate closeness and feeling of security. Interactive social dialogues between Rachel and her mother build on prior knowledge and provide immediate feedback as they discuss each animal as the story progresses. The language they use to label, compare, explain, and classify creates a supportive context for structuring the processes of thinking and concept formation. Each of the domains of development—linguistic, cognitive, social, and emotional—is affected during Rachel's experience, and all play an important role in her development
  • As Rachel began to internalize the actions and language of her mother, she began to use these tools to guide and monitor her own processing behavior until she is now able to take over much of the responsibility for reading the book (Dorn, French, & Jones, 1998)
  • A framework for understanding the interrelated nature of the cognitive, social, emotional, linguistic, and literacy development of children; social interaction; and literature selection in grades K-4 is provided in the appendix. The purpose of the framework is to provide a general guide for teachers, parents, and other caregivers in the appropriate selection of books that takes into consideration the importance of child development.
