Chiral Symmetry is important in a lot of situations. In this talk I will restrict myself to consequences of Chiral Symmetry for the strong interaction. The subject is very broad as can be judged from the lectures and review articles. In its modern form it was founded by Weinberg and Gasser and Leutwyler. I will discuss a few of the basics in sects. 2, 3, 4. The applications to ππ scattering (se...

___________________ Numerous studies have shown that thinking aloud while reading can be an effective instructional technique in helping students improve their reading comprehension. However, most of the studies that examined the effects of think-aloud involve subjects reading individually and carried out in isolation away from the classroom context. Recently, researchers have begun to explore ...

Debugging is a core skill required by programmers, yet we know little about how to effectively teach the process of debugging. The challenges learning debugging are compounded for novices who lack experience and still tools they need program effectively. In this work, report case study in which used think-aloud protocol gain insight into behaviour three students engaged tasks. Our qualitative a...

Locating accurate information on academic topics is a challenge for today’s information seekers. Whilst specialist portals exist, users have a marked preference for finding their own information yet are rarely trained in formal information searching using library resources. Further such electronic resource discovery systems are often complex or highly complicated to use. Work is underway to pro...

This study focused on the cognitive processes involved in learning from text and pictures, when learning both individually and collaboratively. We designed a task in which learners actively engage with text and pictures in a lesson about mitosis, followed by a test of knowledge gained from the task. During the task, think-aloud protocols were collected. Preliminary results show that learners ac...

PDP (Protocol Diaqnostic Program) is a proqram for analyzing think-aloud protocols of subjects solvinq elementary physics problems *. Two versions of PDP implement models of problem solving behaviour at novice and intermediate levels of expertise. In order to compare the behaviour of the models with think-aloud protocols of subjects, PDP is equiped with a think-aloud component, which communicat...

People engage in multiple types of information-seeking strategies within an information-seeking episode. The objective of this pilot study is to investigate search moves and tactics made by end-users when searching for visual information. The pilot study involves 5 undergraduate students from the Department of Journalism and Media Studies at Rutgers University using the AccuNet/AP Photo Archive...

Little research has addressed IT professionals’ script debugging strategies, or considered whether there may be gender differences in these strategies. What strategies do male and female scripters use and what kinds of mechanisms do they employ to successfully fix bugs? Also, are scripters’ debugging strategies similar to or different from those of spreadsheet debuggers? Without the answers to ...

There is a sharp contrast between High Resource Settings (HRSs), commonly seen in developed countries and Low Resource Settings (LRSs), typically found in the marginalised sections of societies around the world. Product design for LRSs is crucial to satisfy unmet or under-served needs of the people living in LRSs. Supporting designers to develop successful products for LRSs demands developing a...

In this plenary talk I give an account on the blossoming role that Brownian motion Theory and Experiment played and still keeps doing so in germinating and advancing several, partially diverse physical disciplines. Although the use of Brownian motion concepts generally most favorably impacted those scientific areas there are also some abuses where the application of such concepts may not descri...
