“…If we recall the research questions and hypotheses, we can conclude that they were justified. Increasing the numerical rating of cognitive complexity has led to lower student achievement and has imposed higher mental effort on students, which is fully consistent with the results of the previously published research (Horvat et al, 2016(Horvat et al, , 2017(Horvat et al, , 2020(Horvat et al, , 2021Knaus et al, 2011;Raker et al, 2013). Careful selection of tasks, with the gradual introduction of new concepts that students have just mastered, can lead to a more permanent formation of knowledge structures and deeper understanding.…”

“…Cohen's d-effect size is 'much larger than typical' (1,86), so an attempt to replicate the study with a larger sample may be justified (Morgan et al, 2011). This had already been confirmed in studies that had the topic of validation of procedures for the assessment of problems' cognitive complexity (Horvat et al, 2016(Horvat et al, , 2017(Horvat et al, , 2020(Horvat et al, , 2021Knaus et al, 2011;Raker et al, 2013).…”

“…However, due to the specificity of domains in chemistry, these rubrics should be further improved. They are developed in the form of a table for assessing the difficulty of the concepts and are of great importance because they are objective and precisely defined by experts (Horvat et al, 2016;2017, 2020. In this study, we have developed a table for the domain of Chemical Kinetics.…”

“…Based on these results, manipulations in the level of cognitive complexity of the problem task can determine the difficulty of the problem (Daniel & Embretson, 2010). As far as chemical education is concerned, cognitive complexity is positively correlated with the difficulty of the problem; at the same time, increasing the cognitive complexity of the problem increases mental effort (Horvat et al, 2016;2017, 2020Knaus et al, 2011;Raker et al, 2013).…”

The main goal of this study was to validate the strategy for the assessment of the cognitive complexity of chemical kinetics exam items. The strategy included three steps: 1) assessment of the difficulty of concepts, 2) assessment of distractor value. and 3) assessment of concepts’ interactivity. One of the tasks was to determine whether there were misconceptions by students that might have influenced their achievement. Eighty-seven students in the first year of secondary school participated in the study. A knowledge test was used as a research instrument to assess the performance, and a five-point Likert-type scale was used to evaluate the perceived mental effort. The strategy was validated using regression analysis from which significant correlation coefficients were obtained between selected variables: students’ achievement and invested mental effort (dependent variables) and a numerical rating of cognitive complexity (independent variable).

“…The p-value is less than 0.05, indicating that there was a statistically significant correlation between student achievement and average self-perceived mental effort in the test. The existence of a significant correlation between students' achievement and mental effort has already been confirmed in studies that have focused on the validation of methods for as-sessing the cognitive complexity of problem tasks [26,27,[44][45][46].…”

The aim of this research was the creation and validation of a procedure for determining the cognitive complexity of problem tasks in the field of salt hydrolysis. The procedure created included an assessment of the difficulty of concepts and an assessment of their interactivity. One of the research tasks was to determine whether there were misconceptions by students that might have influenced their achievement. There were 50 Bachelor of Science in Chemistry students who participated in the study. A knowledge test was used as a research instrument to assess the performance and a seven-point Likert scale to evaluate the invested mental effort. The validity of this instrument for the assessment of cognitive complexity was confirmed by a series of regression analyses, where acceptable and statistically significant correlation coefficients were obtained among the examined variables: student performance and invested mental effort as dependent variables and cognitive complexity as independent variable

The first PhD thesis in the field of Chemistry Education at the Faculty of Sciences, University of Novi Sad, was defended in 1992. This can be regarded as the symbolic dawn of Chemistry Education as a scientific discipline in this region. After the official breakup of the Socialist Federal Republic of Yugoslavia, research that had started in the 1980s, and which was focused on the development of tools for assessing the quality and flexibility of student knowledge, was continued through the 1990s. This research included the application of computers to chemistry teaching, as well as the development of appropriate chemistry learning programmes. In the following period, research focused on the analysis of chemical teaching programmes in the Republic of Serbia, with a special emphasis on the possibility of including eco-chemical content in curricula. Accordingly, potentially efficient models were suggested. The most recent research has been focused on the investigation of the effectiveness of instructional strategies based on a systemic approach and a triplet model of content representation, using combined measures of students’ performance and mental effort. In this regard, tools for the efficient assessment of knowledge (systemic synthesis questions, context-based questions) have been developed along with tools for the efficient assessment of students’ misconceptions (multi-tier tests). Furthermore, in order to make teaching more effective, procedures for assessing the cognitive complexity of chemical problems have recently been developed and subsequently validated both statistically and by applying Knowledge Space Theory.
