What the literature leaves open

  • This points to the need for further work on how visualizations may help learners coordinate descriptions of overall patterns with decisions about the warranted scope of generalization as they develop and refine investigative questions, as well as on how other digital resources, including generative AI tools, may shape this process as such tools become increasingly common in statistical investigations. This suggests that developing a global view of data in the context of large secondary datasets involves not only reading graphs or summary statistics, but also relating interpretations of patterns to judgments about the range over which generalization is warranted.

  • Based on the findings of this study, several practical and research-oriented recommendations can be made. First, the integration of problem-posing activities into middle school statistics instruction appears to enhance students’ ability to represent and interpret data more critically. Therefore, teachers and curriculum developers may consider incorporating structured problem-posing opportunities into regular classroom practice, especially within topics related to data representation and analysis. These activities do not need to replace existing methods but can complement them to promote student engagement and deeper learning. Given the observed improvements in students’ graphical literacy and proportional reasoning, teacher training programs may also include modules that introduce educators to the pedagogical design and implementation of problem-posing tasks. Such training may help teachers facilitate student-centered discussions and guide students in constructing, critiquing, and revising data representations. For future research, this study highlights the value of combining quantitative outcomes with qualitative insights. Researchers could extend this work by exploring the long-term effects of problem-posing activities on different components of statistical literacy, such as data interpretation or informal inference. Comparative studies across different grade levels or educational settings may also help determine the generalizability of the current findings. Finally, further investigation into students’ cognitive and metacognitive processes during problem construction and graph interpretation could offer richer explanations for the effectiveness of this instructional approach.

  • Based on student feedback, the following ideas can improve instruction in similar settings: • Offer Self-Study Modules. Pre-course modules can help students prepare, and post- course access can support continued learning. • Maximize LMS Tools. Organize feedback and learning materials clearly and provide course content recordings that students can access at any time. • Foster Peer Support. Peer mentoring or small tutoring groups can reduce anxiety and create a supportive environment. • Focus on Application with PBL. Students valued PBL methods, indicating they were able • to shift from memorizing formulas to applying them contextually. Improve Recording Quality. Tools like digital whiteboards or screen capture software, used to include audio and board visuals in lecture recordings, can improve student learning experiences. • Coordinate Curriculum. Collaboration across courses is encouraged to ensure that topics are appropriately sequenced to facilitate deep learning while preventing redundancy.

  • Sayfa | 254 Several limitations should be considered when interpreting the findings of this study. First, the analysis relied exclusively on product-based data, namely students’ final graph drawings. As a result, students’ real-time reasoning processes, decision-making strategies, and moment-to-moment difficulties during graph construction could not be directly observed. Second, the study was conducted at a single BİLSEM center, which limits the generalizability of the findings to gifted students in other regions or instructional contexts. Third, the absence of process-oriented data sources—such as interviews, classroom observations, or think-aloud protocols—restricts deeper insight into the cognitive and metacognitive mechanisms underlying students’ errors. Finally, although a structured rubric was used, the potential for scorer bias cannot be fully eliminated, despite efforts to ensure consistency and reliability. These limitations highlight the need for cautious interpretation and point to important directions for future research.

  • Interest in data analytics is booming, and the need for business students to be proficient in this field remains strong. Academic programs aimed at domain experts should offer data analytics courses that leverage students’ domain knowledge while accommodating their limited background in computer programming and statistics, thereby maintaining motivation through technically challenging yet accessible content. Drawing from the academic literature on the topic, student reflections, and our own experiences, we presented several lessons learned that may help other instructors develop similar courses. It is important to note that the course was developed in the context of the Dutch educational system, which is characterized by high industry involvement and oversight. The Dutch culture also values data-driven decision-making. Together, these factors ensured the needed legitimacy to invest resources in developing this course. This impetus and resources may not be available in other settings. However, we also acknowledge that the data science and data analytics fields are still developing rapidly, and therefore continuous monitoring and redesign of data analytics courses is necessary. For example, generative Artificial Intelligence (AI) tools (e.g. ChatGPT and Microsoft Copilot) are increasingly being used by students to help them code in R. Our initial experience with allowing students to use AI to generate code is that it can help students who have already mastered basic programming concepts make progress more quickly. However, when students lack a solid understanding of basic R syntax, they struggle to use prompts effectively and to apply AI-generated code to their assignments. Although the quality of AI-generated code is rapidly improving, hallucinations (references to non-existent packages or functions) remain a persistent issue. This can lead to frustration among both students and instructors, as they often Kokkinou, R. Mazinani, H. van Gils: Bridging the Gap: Teaching Data Analytics to Business Students using R 461 are unaware that hallucination is at play. Based on anecdotal evidence, we anticipate that as AI-generated code continues to improve, it will become an increasingly relevant educational tool. For now, however, further research is needed to explore how generative AI can best support student learning and to examine its associated ethical implications (Becker et al., 2023). Future course development should therefore critically assess the added value of these tools and consider how to integrate them effectively to enhance student learning outcomes.

  • Mathematics instructors should enhance instructional numeracy through continuous professional development Continuous professional development (CPD) programs help instructors strengthen their mathematical content knowledge, pedagogical strategies, and instructional clarity. Regular training ensures that teachers remain updated with effective numeracy teaching approaches and modern instructional practices, leading to improved classroom delivery and student understanding. Instructional strategies should integrate real-life mathematical applications Embedding real-world contexts in mathematics instruction allows students to connect abstract concepts to practical situations. This approach enhances relevance, engagement, and comprehension, making mathematical concepts easier to understand and apply beyond the classroom. Institution should provide training programs focused on pedagogical numeracy Educational institutions play a vital role in supporting teacher development by offering structured training programs that focus on pedagogical numeracy. These programs equip instructors with strategies for simplifying complex concepts, improving instructional clarity, and addressing student learning difficulties effectively. Future research may explore additional factors affecting student learning outcomes such as motivation and learning environment Further studies are encouraged to examine other influential variables such as student motivation, learning environment, cognitive abilities, and study habits. Exploring these factors will provide a more comprehensive understanding of what affects mathematics achievement in higher education. By aligning instructional strategies with students’ cognitive needs and learning preferences, educators can effectively address challenges in understanding mathematical concepts such as symbols and quantifiers. These interventions not only improve students’ conceptual understanding but also foster critical thinking, problem-solving skills, and overall mathematical proficiency, contributing to improved academic performance and long-term learning success.

  • Based on the findings of this study, it is recommended that technology becomes an integral part of the teaching process. Using interactive applications, simulations, and technological tools helps bring abstract concepts closer to students’ practical experiences. These tools not only increase their engagement but also enable deeper understanding of statistics and probability through hands-on, visual experiences. Therefore, schools and educational institutions should invest in the necessary technological infrastructure and ensure these tools are accessible to all students. A key element for improving this contemporary approach is continuous teacher training. Teachers must be prepared to use technology effectively and create a learning environment that encourages active student participation. Therefore, it is crucial to provide them with specialized training on modern teaching methods and digital applications that foster students’ analytical and creative skills. Moreover, the curriculum should be adapted to include more practical elements that help students apply their theoretical knowledge in real-world contexts. Incorporating activities that involve data collection and statistical analysis in real tasks can improve students’ ability to connect theory with practice. This approach will help students develop data-driven decision-making skills and solve complex problems they may encounter in everyday life. Additionally, there should be a continuous effort to provide digital resources and learning materials aligned with this approach. Resources such as e-books, video lessons, and interactive simulations can greatly support both teachers and students by making concepts clearer and more accessible. Furthermore, it is encouraged that teachers tailor their approach to the individual needs of students. Some students may require additional support to fully grasp the concepts, and therefore, a more personalized approach would be highly effective in providing the right level of assistance for each student. Lastly, schools should foster a supportive environment for implementing these contemporary approaches. Investing in the necessary technological infrastructure, ensuring access to digital resources, and incorporating technology into teaching should be a priority. These measures, combined with a continuous focus on teacher training, will help achieve better results in students’ understanding of statistics and probability and improve the overall quality of education.

  • One approach to improving data literacy is to teach a course devoted to data science but, given the lack of consensus over the term “data science,” just what should an introductory data science course include? The author argues that at the secondary level, an introductory data science course should strive to teach data‐scientific thinking, which has statistical thinking at its core, blended with some computational thinking, and with a dash of mathematics.
