There is evidence that both criteria are being satisfied.  \nChemistry Departments have been struggling for some time now with the reluctance of students to carry out even simple mathematical exercises. Physical chemists have borne the brunt of this problem but matters came to a head in Liverpool a few years ago when inorganic chemists realised that a substantial minority could not work out their titrations. The staff agreed that this constituted a skill that all competent professional chemists must acquire and so instituted a test which students had to pass to proceed further in their course. This resulted in the test being retaken as often as necessary until a pass mark was obtained. The amount of work required of staff in setting and marking as many tests as were required can be imagined.  \nAt the same time, staff in the computer assisted learning facility were turning their attention to the question of computer based assessment and a quiz on volumetric calculations seemed to provide the ideal vehicle for a pilot study. The objectives were:  \n1. to test the feasibility of examining a large class of students (ca. 100) using the in-house computer network of 15 machines. This would deal with such matters as timetabling, reliability, security etc.;  \n2. to assess the acceptability of such tests from the student point of view;  \n3. to assess the acceptability from the staff point of view;  \n4. to assess the educational effectiveness; and  \n5. to quantify any resultant time savings.  \nThe program  \nThe major requirement of this program was that, since the test would have to be taken on several different occasions students must be presented with different calculations to prevent prior knowledge conferring an advantage. The CTI Centre provided details of all the available packages, but despite the excellence of some of them, they all failed this criterion. In a typical example, a numeric question and its answer must be pre-programmed with no provision to calculate the answer from the question nor to use random input. This would entail 100 separate numeric inputs for each question together with the corresponding answers to give a different value for each student-clearly time consuming and probably not worthwhile. Accordingly we wrote our own.  \nThe Chemistry Quiz (CQ) is a program (now a series of programs) used to test students'competence with the everyday numeric manipulations required in chemistry and is designed to complement the existing range of software available. CQ allows the generation of random input data so that every student receives a different value even when attempting the same question. CQ is designed only for this type of question and makes no attempt to incorporate textual input, multiple choice or other features found in other products. All computations use integer arithmetic to avoid rounding errors, with sensible use of significant figures. Quizzes have been produced covering volumetric calculations, spectroscopy, thermochemistry, particles and waves, and algebraic manipulation.  \nModes  \nCQ may be set up for student use in one of three different modes:  \n1) Practice mode  \nIn this mode the student is presented with a total of 20 questions chosen at random from all the available question types for a particular quiz. The total of 20 has been chosen to minimise time and resources and to provide a reasonable length of study. In this mode a student may opt to exit at any time or, indeed, to repeat the quiz an unlimited number of times. The student also has the ability to choose a particular question type at any time-useful for tutorial hom","cbCainzZ2YpNhBs2","https://ap.wps.com/l/cbCainzZ2YpNhBs2","pdf",40258,"English","# Introduction\n# The program\n# Modes\n## Practice mode\n## Directed Practice mode\n## Examination mode\n# CQ parts: Quizmaker, Quizzes, Analyser\n# Quizmaker\n# Quizzes","[{\"question\":\"Why was the Chemistry Quiz (CQ) developed?\",\"answer\":\"CQ was created to ensure minimum numeric competency among students and to reduce staff time required for repeatedly setting and marking many tests.
