An EvaluationWhat Is Game Based Learning? An EvaluationMany mickle believe that gaming is addictive and can lead to violence, a belief that is not substantiated by research. Researchers have shown that the source of behavioral problems of young mass who play video games comes from elsewhere. One study found that people who play video games spend just as much time reading, doing homework or active in other social activities as people who do not play games at all. This raises the heading can video games be use for accomplishment in the classroom and would they have positive results?When gentility starts to feel dull, we are not be engaged or motivated, which means we are not actually schooling. According to Foreman we can timbre at the lecture as an poser. With all the engine room being thrown at young people to day, they are going to say, why am I sitting in this lecture listening to this person? Learning is just not memorization it means the act or process of acquiring knowledge or skill. Students do not need to spend much time in the classroom to learn how to think and perform. They need effective, engaging experiences that can motivate them in the nurture process. Educational games can be a powerful tool for teaching and learning. These games are apply to reinforce learning, they offer immediate feedback, recurring gratification and prolong the avocation of students.Why it worksGame-based learning is a simple concept, where games are used as a learning tool to engage students. In Jane McGonigals book, a game is defined as an activity that has goals, rules, a feedback system, and voluntary participation (pg 100). Some pedagogic considerations that are derived from game based learning are that content and/or skills can enhance learning vs. traditional methods Students can build the ir own games in order to learn and develop skills They can use game mechanics in the learning environment, for example utilize levels instead of grades, coined gamification of the learning process.In 2003 author, pile Paul g-force wrote the book, and in it he described the impact of cognitive development with game play. Gee developed 36 different learning formulas that games being used in education should have. From these principles we can look at game based learning from two perspectives. The first is learning effectiveness. The second is engagement.When considering learning effectiveness, we can consider whether the game provides meaningful learning activity or whether the game is just a fun activity and does not necessarily lead to learning. We can look at what the learning outcomes are including memorization, knowledge, under(a)standing, discount and creativity. For all these various learning outcomes, games can provide an enriched learning experience.The second perspecti ve, the elements of engagement from Games Based Learning (GBL) we can ask does the game enhance learner motivation, does the game provide a fun learning experience? Is it interesting or is it a very tedious, boring learning experience? Does it add to learner concentration? Does it get the learners full attention? And finally learning by doing, games can provide an experience where the learner has to intensely engage in various activities.Where is it going?Over the last decade, research and interest in GBL has increase, as has the diversity of games themselves. Serious games and computer simulations offer an interesting context for learning because they both reinforce student motivation. Researchers found that students playing serious games or who participated in computer simulations were a pass around more than active as they manipulated objects. Students also had control over their actions and were more engaged in their learning. Researchers found that animation in the games incr eased motivation, and that students were more likely to return to activities that included animated graphics. They also found that serious games support inductive, experiential learning, with a genuine constructivism approach. Online gaming provides a context for adaptive learning, because they allow for multiple personalized paths or itineraries. Communication among players also introduces a social aspect that opens doors to knowledge acquisition with peers. Challenged-based and collaborative games are an emerging category of games that seem particularly appropriate for higher education. These games allow students to use skills for research, collaboration, problem solution, writing, leadership, digital literacy and many more. They are open-ended and occur in both online and non-digital forms. Games will doubtless evolve in the future and therefore GBL will also need to evolve, we are seeing fresh types of gaming, such as alternate reality games, social/mobile games, we are also seeing in advance(p) new ways to use GBL.ConclusionGame-based learning has gained more traction in recent age and is becoming more accessible with many benefits. Game-based learning can make learning more situated, contextualized and personalized. GBL can be used for learning content and skills, including 21st century skills like innovative problem solving and collaboration. GBL can even be used for practicing and honing existing skills. Game based-learning engages students, and if students are engaged they will plow learning rather than view it as a tedious boring learning experience.AC Voltammetry Principles, Advantages and DisadvantagesAC Voltammetry Principles, Advantages and Disadvantages NameTEH YU JIE (K)NOOR HASIRA BINTI SAMSUDINNUR NADIAH BINTI ABU BAKARNUR NIQMAH BINTI MUSANUR SYAHIRAH BINTI KHAIRUDDINKHANG EE WENINTRODUCTIONNobel Prize winning chemist Jaroslav Heyrovsk facilitated voltammetry by the baring of polarography by in the year of 1922. Alternative current vo ltammetry was invented in 1950s and developed intensively by D.E Smith.Alternative current (AC) voltammetry is an accurate electro analytic thinking method and combination with preconcentration will enhance the sensitivities of this analytical proficiencys. AC Voltammetry broadly involves in the application of a sinusodially oscillating voltage to an electrochemical cell. The AC experiment is used in conjunction with a fixed amplifier or frequency analyser which will increase sensitivity easily over the early described techniques. AC voltammetry can also reveal the important of mechanistic and kinetic information which is not easily available when use the tradition voltammetric techniques.Measurement of AC voltammetric is usually used in an electrochemical cell and the dominate mode of transport is spreading. A stiff DC channelize or voltage expanse will often combined with the AC voltage.The following figure shows a cyclic voltammetric planetary house with an AC perturbati on.Alternating potential usually has a frequency of 50-100Hz and 10-20mV amplitude. The AC signal causes a perturbation in the surface concentration and DC potential ramp maintained the concentration. The resulting AC current is plotted against the potential. For example, voltammogram appears a handbill, the potential of which is the same as the polarographic half-wave potential. At this region, the sinusoid has supreme impact on the surface concentration like on the current.For a rechargeable system, such a response is actually the derivative of the DC polarographic response. The concentration of the analyte is comparative to the height of the AC voltammetric prime quantity and for a reversible answer to the square root of the frequency (), the term is the amplitude.WORKING PRINCIPLEAC Voltammetry typically involves the application of a sinusodially oscillating voltage to a electrochemical cell. When used in conjuction in the ac experiment with a lock in amplifier or frequen cy analyser. It offers a considerably increased sensitivity compared to the early described techniques. It can also reveal necessary mechanistic and kinetic information that are not easily available by using some other tradition voltammetric techniques.Usually, public exposure is perfomed as it was the dominate mode of transport. The AC voltage is often combined with either a steady DC signal or voltage sweep.There are three component steps conglomerate in an electrochemical process, mass transport,chemical and adsorption steps and negatron transfer. They all are actually loan to the total potential drop across the cell. If an AC current flows, it will be necessary to state purely ohmic electrical resistance from non-ohmic,complex and normally frequency dependent resistance(often term impedance).Besides,treatment of the AC response of electrochemical cells will follow the pathway with initially a worldwide treatment. The treatment of the two simpler cases of purely diffusion controlled and purely electrochemically controlled reactions will be conducted.Under AC measurements,there are 5 methodsInfluence of transport processes on the ac impedances of an electrochemical cell.Equivalent circuit for an electrode-diffusion-limited reaction.(the circuit elements describing the flow of ac current through an electrode comprises an electron transfer resistance,R and Warburg impedance,Z in series.AC impedance of an electrode where the electron transfer process is rate limiting.Logarithmic or bode plot representations.Electrode reactions under mixed controlAlternating current bridges use the principle of balance betwixt the variable impendance, ZS and an electrochemical cell under study. An electrode process normally consists of a resistance RS in series with a capacitance CS.The resistance includes the resistive components of the electrode process of the solution and the capacitance is overdue to the working electrode. A combination of capacitance and resistance has been used in parallel. The analysis is more carried out in these conditions in terms of admittance Y=1/ZPotentiostat is more convenient to use when it is important to apply a d.c potential to the cell in addition to the a.c perturbation. Potentiostat is simultaneously applies the d.c potential and the spotting rather than conventional detector. It is good stability in the utilise potential and accuracy for wide sphere of frequencies while the electronic component of the potentiostat is only limited by these characteristics. This arrangement is known as a potentiostatic bridge.The accuracy of bridges at high frequencies are depends on cell design. This is due to the ions are move faster than the time needed for rearrangement of the ionic atmosphere and occur above 10 MHZ . The technique is actually very similar to the normal frequencies but it was also time consuming.This technique also has a disadvantage such as the impendance of the whole cell is measured. In the investiga tion of electrode process the disadvantage when one is interested in the properties of one of electrode. By using an auxiliary electrode with an area large relative to that electrode, it is possible to reduce the contribution of the unwanted components.ADVANTAGES AND DISADVANTAGESAC Voltammetry is one of the techniques based on the analysis of faradaic impedance. A low-amplitude curved voltage is given to the working electrode, which is also established at some DC voltage with picture to the reference electrode. Because of the difference in the time scale, the AC component of the total current can be readily differentiated from the DC component. The kinetic parameters can be carried out either from the amplitude of each current or from the phase angle between the AC current and AC voltage (C.G Zoski, 2007).The evidentiary advantage of AC Voltammetry is that it allows relatively easy evaluation of the solution resistance and double layer capacity. Without simplifying assumptions t he analysis of faradaic impedance even for a simple response is quite complicated. The commonly used assumption is that the DC and as components of the total current can be uncoupled is reasonable because AC Voltammetry is typically applied to measure fast electrode kinetics.The other advantage of voltammetry as quantitative method of analysis is its capability for analyzing two or more analytes in a single sample. As long as the components behave independently, the resulting voltammetry for a multi component mixture is a summation of their respective individual voltammograms.Voltammetry has been used for the quantitative analysis of a wide variety of samples, including environmental samples, clinical samples, pharmaceutical formulations, steels, gasoline, and oil.Some advantages and disadvantages are specified in the form of accuracy, precision, sensitivity and selectivity. The accuracy of a voltammetric analysis usually is limited by ability to correct for correspondence currents , particularly those due to charging. For an analyte at the parts-per-million level, an accuracy of 13% is routine. Accuracy decreases when analysing samples with significantly smaller concentrations of analyte. clearcutness is generally limited by the uncertainty in measuring the limiting current or the peak current. Under most conditions, a precision of 13% is reasonable. One exception is the analysis of ultratrace analytes in complex matrices by baring Voltammetry, in which the precision may be as poor as 25%.In many voltammetric experiments, we can remediate the sensitivity by adjusting the experimental conditions. For example, in stripping voltammetry we can improve sensitivity by increasing the deposition time, by increasing the rate of the elongated potential scan, or by using a differential-pulse technique. One reason that potential pulse techniques are popular is that they provide an improvement in current relative to a linear potential scan.Lastly, selectivity in volta mmetry is determined by the difference between half-wave potentials or peak potentials, with a minimum difference of 0.20.3 V for a linear potential scan and 0.040.05 V for differential pulse voltammetry. We often can improve the selectivity by adjusting solution conditions. The addition of a complexion legend, for example, can substantially shift the potential where a species are oxidized or reduced to a potential where it no longer interferes with the intention of an analyte. separate solution parameters, such as pH, also can be used to improve selectivity ( D.Harvey,2000).COMPARISON OF AC VOLTAMMETRY WITH OTHER TYPES OF VOLTAMMETRYVoltammetry is a category for electro analytical method generally used in analytical chemistry and various industry processes. Consist a lot of example of voltammetry that been used such linear sweep voltammetry, staircase voltammetry, square wave voltammetry.Others example like cyclic voltammetry consist of method that can be used to determine diff usion coefficient and half-cell reduction potentials. Anodic stripping voltammetry are also the example of voltammetry that are quantitative analytical method for trace analysis of metal cations. Then, cathodic stripping voltammetry are also as example of this voltammetry that are quantitative analytical method for trace analysis of anions.Other than that, chemisorptive stripping voltammetry is a quantitative and analytical method for trace analysis. Alternating current voltammetry and polarography in example of voltammetry that polarography is a subclass of voltammetry where the working electrode is a dropping mercury electrode that useful for its wide cathodic range.Lastly, rotated electrode voltammetry is a hydrodynamic technique in which the working electrode. This technique is useful for studying the kinetics and electrochemical reaction mechanism for a half reaction. Then, the normal pulse voltammetry, differential pulse voltammetry and chronoamperometry.RESEARCH IN AC VOLTAM METRYAc voltammetry is a method that seldom used on the determination of master(a) elements. In general principle, the determinations are usually done is a more conventional way, that is by connecting two electron reversible electrochemical process. During the process, the mercury is oxidized to form mercury (II) ions and the electrode surface will formed at the electrode surface.In this research, we will be analyzing elemental sulfur with AC voltammetry. Generally speaking, the elemental sulfur will abide the chemical pretreatment. For example, the process with solvent such as ethanol and toluene-methanol or methanol-pyridine. The process involved broadly organic solvent. Why the process is carried out with pretreatment but not direct determination? This is because the aqueous solutions mostly contain too less elemental sulfur to be determined.To overcome the problem, some scientist suggest that using acidification of sample to pH 5 and then with electrochemical treatment. The m ethod itself has a higher detection rate compared to the previous one, but actually still too low for economical values.According to Batuna (1992), they try to determine the elemental sulfur by using direct determination method. And the source is natural water. The researchers are conducting the research using phase sensitive ac voltammetry because the instrument is easier to be found in the laboratory in the authors lab.The research continues with using a PAR Model 303A static mercury drop electrode from EG G Princeton Applied Research. It was connected to a BAS-100A electrochemical analyser from Bioanalytical System that located in the West Lafayatte. They used a reference electrode of Ag/AgCl and an auxillary electrode of platinum. The instrument takes the measurement at 80 Hz and a intonation scan rate of 1 mV s-1. The temperature of the conditions was at room temperature. The solutions were deaerated for 15 minutes by using nitrogen gas and then doubly distilled and filtered with the Milli-Q filter. All measurement was actually made at the pH 10 to prevent the formation of volatile H2S.The stock solution was prepared from using the reaction between elemental sulfur and toluene. The solutions have to be prepared just before the measurements were made. This is because to prevent contamination and more complete reaction can be conducted.PAR Model 303A static mercury drop electrodeRESULTSThe determination of sulphide in aqueous solution are based on the insoluble mercury (II) sulphide during the assemblage period at potential more positive than ca- 0.58V.Hg + S2- HgS + 2eA and B were demonstrate the typical ac voltammogram of sulphide in 0.5 moldm-3 NaCl-NaOH. C is a negative going scans of 110-6 moldm-3 after 0-300s accumulation at a potential 0.5V. D shows that positive going scans of 110-4 moldm-3 sulphide after 0-120s accumulation at a potential at 0.8 V.The difference between the peaks obtained using negative- and positive-going scan directions are more elevate to the negative direction. It is also important to note that there is actually no effect of accumulation under conditions on the peak height obtained with a positive-gong scan . This agrees well with the explanation that during the positive-going scan, the anodlc dissolution of mercury occurs, which is proportional to the adsorbed sulphlde on the mercury electrode.REFERENCESZoski,C., (2007), Handbook of Electrochemistry, Elsevier Publication, Amsterdam Netherland, pg 645.,Retrieved at 15/3/2014.
