Computer-Based Testing on Physical Chemistry Topic: A Case Study

Article excerpt

ABSTRACT

According with national trends in the objective evaluation of undergraduate students' knowledge, an auto-calibrated online evaluation system was developed. The aim of the research was to assess the knowledge on physical chemistry topic of the undergraduate first year students' at the Faculty of Materials Science and Engineering, the Technical University of Cluj-Napoca, Romania by the use of the developed auto-calibrated system. The methodology of multiple-choice questions construction and the evaluation methodology are presented. The students performances in terms of number of correct answers and time needed to give a correct answer were collected and analyzed. The future plans of system development are highlighted.

Keywords: Auto-calibrated online evaluation, multiple choice questions (MCQs), physical chemistry, undergraduate students

INTRODUCTION

In universities, the cardinal premise of the end-of-course examination is to assess as objective as possible the students' knowledge and skills acquired on the courses, practical activities and seminars.

Development of communication (Valcke & De Wever2004) and information technologies (Kidwell, Freeman, Smith & Zarcone 2004; Matusov, Hayes & Pluta 2005) provide today the opportunity of creation interactive computer-assisted environments used in many domains, including in chemistry training (Beasley 1999; Frecer, Burello & Miertus 2005; Chen, Chen & Cao 2002) and evaluation (Timmers, Baeyens, Remon & Nelis 2003; Stewart, Kirk, LaBrecque, Amar & Bruce 2006).

In many academic domains, educational measurement has been moving towards the use of computer-based testing, define as tests or assessments that are administered by computer in either stand-alone or dedicated network, or by other technology devices linked to the Internet or the World Wide Web most of them using multiple choice questions (MCQs). The computerassisted evaluation strategies are used in medicine (Oyebola, Adewoye, lyaniwura, Alada, Fasanmade & Raji 2000), chemistry (Ananda, Gunasingham, Hoe & Toh 1989), language testing (Brown 1997), biology (Evans, Gibbons, Shah & Griffin 2004), computer science (Barker & Britton 2005), and economics (Judge 1999).

Currently in Romania, at the Faculty of Materials Science and Engineering, the Technical University of Cluj-Napoca, the traditional method (a combination of essay examination, practical examination and/or tutor assessment) is the most frequently used as evaluation of students' knowledge. In the last years, the number of students increased and the conventional examination method become time consuming in term of the examination time as well as in term of papers assessment. Thus, the students received their final marks beyond the day of examination (the next day after examination in the best case and up to one week or more). A solution of examination in large classes of students is an automated testing system which to allow testing the students knowledge and displaying immediate on the screen the examination results.

According with national and international trends in objective undergraduate students' knowledge evaluation, and starting from the experiences obtained by creation of the multiple choice examination system for general chemistry topic (Nascu & Jäntschi 2004a; Nascu & Jäntschi 2004b), an auto-calibrated online evaluation environment was developed (Jäntschi & Bolboaca 2006). The aim of the research was to study students' knowledge on physical chemistry topic by the use of the developed auto-calibrated online evaluation system.

MATERIAL AND METHOD

Auto-calibrated online evaluation system

The auto-calibrated online evaluation system (Jäntschi & Bolboaca 2006) embodies:

* Multiple-choice banking. The characteristics of the MCQs and respectively of the multiple-choice banking are as follows:

* The question anatomy: a statement or a situation, a problem (steam) and a list of five suggested solutions (options). …
