Student module

Table I. Correlation of Student Modules to Massachusetts Frameworks...

The student module, the whom part, stands for the accurate definition of the student is current knowledge state (what he knows - either correct or incorrect - and does not know). It can be a (static) data stmcture, representing a subset of the domain knowledge mastered by the learner (an overlay model), or it can be a set of (possibly wrong) procedures describing the student past behaviour (a buggy model).

The student module was structured in three parts. Each part has a specific instructional function (De Vos, Bulte and Pilot, 2002) ... 

III) Application phase. Teachers were motivated to redesign a particular chapter of their traditional textbook about the structure and properties of water, but they were not able to redesign this chapter according to the instructional functions of the module. Contrary to our expectations, this task was too ambitious for them. After the course when interviewed, teachers indicated some confusion about the course objectives was this course about improving the student module or about teacher learning Furthermore, they also mentioned that, in their opinion, the functions of parts of the module were too abstract to be used in practice. 

This implies that a thorough revision is needed of the course design and the student module. Before asking teachers to construct their own context-based module, they need a more detailed illustration of how such a context-based approach can become operational in their teaching practice. 

It was decided that in the redesigned student module the instructional functions of the context-based approach some key characteristics of a context-based approach... 

The requirements for the student modules to be used in this type of teacher training are high characteristics of a concept-based approach should be clear, e.g. there should be a transparent cormection among the introductory experiment and the chemical concepts that should give an answer to student questions which are evoked, and the use of theory in the practical assigmnents. 

The following are exercises that have been used with honors students and that seem to be both interesting and challenging. In many cases only the rudimentary coded solution is given. From this one can build much more sophisticated code and in many cases create Module functions that can be used repeatedly with different parameter values. Note that all of these separate problems were run as if the Kernel had to be restarted with each computation. Running sequentially without adding statements to clear variables will result in absurd output. 

These new mini video lectures, playable on video iPods, iPhones, and MP3 players as well as on iTunes, include animations and problems for a quick summary of key general chemistry concepts, e-Flashcards in selected modules briefly introduce a key concept and then test student understanding of the basics with a series of questions. Modules are also available separately. Go Chemistry is included in CengageNOW. To purchase, enter ISBN 0-495-38228-0 at www.ichapters.com. 

The modules are computer-based laboratory simulations with engaging activities that emphasize experimental design and visualization of structures and processes at the molecular level. The modules are designed to help students connect chemical principles from lecture with their practical applications in the lab. Every module has a built-in accountability feature that records section completion for use in setting grades and a workbook for students to record and interpret their work. 

Used either as prelaboratory preparation for related laboratory activities or to expose students to additional laboratory activities not available in their program, these modules motivate students to learn by proposing real-life problems in a virtual environment. Students make decisions on experimental design, observe reactions, record data, interpret these data, perform calculations, and draw conclusions from their results. Following a summary of the module, students test their understanding by applying what they have learned to new situations or by analyzing the effect of experimental errors. 

Burke and his students (11) have published a proposal for solving the non-linearity problem associated with CC and the consequent correlation noise. They used a constant frequency multiple injection signal while this occurred, this frequency was modulated. Before each injection, a random number was generated to determine the magnitude and sign of the deviation from the carrier frequency for the next injection time. Thus, the next... 

Another example Haack mentioned is the text Chemls try for Changing Times a chemistry textbook for nonchemistry majors. The nonchemistry major student population includes students in education, business, and health fields, such as physical therapy, art, and history. Typically these students are trying to satisfy a science requirement for the university s core requirements and will not take any additional chemistry. The textbook has very little math and focuses on concepts. The new edition has 10-12 new educational modules that cover green chemistry. 

The module A green chemistry topic is discussed in class, and then the instructor directs the students to visit the Web page to read and study the material. 

University of Illinois Urbana-Champaign. Materials Science and Technology. Available online. URL http //matsel.mse.uiuc.edu/ tw/. Accessed May 28, 2009. Thanks to the hard work of dozens of high school teachers, as well as a number of college professors and students, this Web site presents a highly informative set of pages on the science of materials. There are modules on ceramics, metals, polymers (plastics), composites, concrete, and more. 

Inquiry-driven student learning of thermodynamics is achieved with the implementation of the Virtual Substance molecular dynamics simulation program. Problem solving and critical thinking skills are developed by students through the completion of the modules described in this chapter. In addition, Virtual Substance is shown to be exceptionally numerically accurate as a tool for doing authentic science.
