Analysis of Item Writing Flaws in a Communications Skills Test in a Ghanaian University

Adhering to the rules governing the writing of multiple-choice test items will ensure quality and validity. However, realizing this ideal could be challenging for non-native English language teachers and students. This is especially so for non-native English language teachers because developing test items in a language that neither they nor their students use as their mother tongue raises a multitude of issues related to quality and validity. A descriptive study on this problem was conducted at a Technical University in Ghana which focused on item writing flaws in a communication skills test. The use of multiple-choice test in Ghanaian universities has increased over the last decade due to increasing student intake. A 20-item multiple-choice test in communication skills was administered to 110 students. The test items were analyzed using a framework informed by standard item writing principles based on the revised taxonomy of multiple-choice item-writing guides by Haladyna, Downing and Rodriguez (2002). The facility and discrimination index (DI) was calculated for all the items. In total, 60% of the items were flawed based on standard items writing principles. The most violated guideline was wording stems negatively. Pearson correlation analysis indicated a weak relationship between the difficulty and discrimination indices. Using the discrimination indices of the flawed items showed that 84.6 % of them had discrimination indices below the optimal level of 0.40 and above. The lowest DI was recorded by an item with which was worded negatively. The mean facility of the test was 45%. It was observed that the flawed items were more difficult than the non-flawed items. The study suggested that test items must be properly reviewed before they are used to assess students’ knowledge.

ASSESSING THE VALIDITY AND RELIABILITY OF SCIENCE MULTIPLE CHOICE TEST USING RASCH DICHOTOMOUS MEASUREMENT MODEL

Multiple choice tests are widely applied to assess students’ knowledge in science education. This study aimed at assessing the validity and reliability of Science Multiple-choice Test in Malaysia. The items for this test were formulated by the researcher together with a panel of science teachers and the head of the science department with close reference to Secondary School Standard Curriculum (KSSM) syllabus. The test consists of 50 multiple-choice items with four options. Rasch measurement model was adopted to evaluate the quality of the Science Multiple-choice Test in terms of reliability analysis, item polarity analysis (PTMEA-CORR), item fit analysis and Principal Component Analysis of Residuals (PCAR). The reliability analysis was performed using Cronbach’s Alpha, and the results of reliability and separation index respectively indicated good reliability level of the test items. In order to improve the validity of the test, two negatively worded items (Q39 and Q40) were removed. Lastly, the PCAR analysis showed the unexplained variance in the 1st contrast (5.4%) was found to be well controlled and was below the ceiling value of one-third of the variance explained by the item (18.7%). However, the positive value of the disattenuated correlations indicate no evidence of the presence of secondary dimension.

Ensuring Scalability of a Cognitive Multiple-Choice Test through the Mokken Package in R Programming Language

This study investigated the scalability of a cognitive multiple-choice test through the Mokken package in the R programming language for statistical computing. A 2019 mathematics West African Examinations Council (WAEC) instrument was used to gather data from randomly drawn K-12 participants (N = 2866; Male = 1232; Female = 1634; Mean age = 16.5 years) in Education District I, Lagos State, Nigeria. The results showed that the monotone homogeneity model (MHM) was consistent with the empirical dataset. However, it was observed that the test could not be scaled unidimensionally due to the low scalability of some items. In addition, the test discriminated well and had low accuracy for item-invariant ordering (IIO). Thus, items seriously violated the IIO property and scalability criteria when the HT coefficient was estimated. Consequently, the test requires modification in order to provide monotonic characteristics. This has implications for public examining bodies when endeavouring to assess the IIO assumption of their items in order to boost the validity of testing.

Imparare dagli errori: apprendenti russofoni di italiano LS/L2

The study deals with written errors in Italian language made by Russian learners and their use in Italian LS/L2 lessons. The cultural-linguistic background of Russian learners of Italian and the differences in the morphosyntax of Italian and Russian are partly accounted for causes of such errors. The paper focuses on the didactic advantages of ranking multiple choice test on the base of the degree of incorrectness of the proposed choice: it supports the importance of using systematic errors as a source to create ad hoc multiple choice, and to trigger students’ conscious second language learning.

Special Teaching Formats during the COVID-19 Pandemic—A Survey with Implications for a Crisis-Proof Education

Modern teaching formats have not been considered necessary during the COVID-19 pandemic with uncertain acceptance by students. The study’s aim was to describe and evaluate all measures undertaken for theoretical and practical knowledge/skill transfer, which included objective structured practical examinations (OSPEs) covering a communication skills training. The students’ performance in the OSPE as well as the theoretical knowledge level were assessed, of which the latter was compared with previous terms. In conservative dentistry and periodontology (4th and 5th year courses), theoretical teaching formats were provided online and completed by a multiple-choice test. Practical education continued without patients in small groups using the phantom-head, 3D printed teeth, and objective structured practical examinations (OSPEs) including communication skills training. Formats were evaluated by a questionnaire. The organization was rated as very good/good (88.6%), besides poor Internet connection (22.8%) and Zoom® (14.2%) causing problems. Lectures with audio were best approved (1.48), followed by practical videos (1.54), live stream lectures (1.81), treatment checklists (1.81), and virtual problem-based learning (2.1). Lectures such as .pdf files without audio, articles, or scripts were rated worse (2.15–2.30). Phantom-heads were considered the best substitute for patient treatment (59.5%), while additional methodical efforts for more realistic settings led to increased appraisal. However, students performed significantly worse in the multiple-choice test compared to the previous terms (p < 0.0001) and the OSPEs revealed deficits in the students’ communication skills. In the future, permanent available lectures with audio and efforts toward realistic treatment settings in the case of suspended patient treatment will be pursued.

The Position of Distractors in Multiple-Choice Test Items: The Strongest Precede the Weakest

Middle bias has been reported for responses to multiple-choice test items used in educational assessment. It has been claimed that this response bias probably occurs because test developers tend to place correct responses among middle options, tests thus presenting a middle-biased distribution of answer keys. However, this response bias could be driven by strong distractors being more frequently located among middle options. In this study, the frequency of responses to a Chilean national examination used to rank students wanting to access higher education was used to categorize distractors based on attractiveness level. The distribution of different distractor types (best distractor, non-functioning distractors…) was analyzed across 110 tests of 80 five-option items administered to assess several disciplines in five consecutive years. Results showed that the strongest distractors were more frequently found among middle options, most commonly at option C. In contrast, the weakest distractors were more frequently found at the last option (E). This pattern did not substantially vary across disciplines or years. Supplementary analyses revealed that a similar position bias for distractors could be observed in tests administered in countries other than Chile. Thus, the location of different types of distractors might provide an alternative explanation for the middle bias reported in literature for tests’ responses. Implications for test developers, test takers, and researchers in the field are discussed.
