1 Research Question Plan Kaarthik Chandrashaker College of Humanities and Social Sciences, Grand Canyon University PSY 520: Graduate Statistics Dr. Jim Dudleston July 15, 2023

2 Research Question Plan Conventional teacher-led instruction continues to be the prevailing approach in the majority of elementary mathematics classrooms (Wu et al., 2020; Boaler, 2016). However, studies conducted in Taiwan by Yeh et al. (2019) have shed light on the limitations of this traditional instructional method, indicating that many students struggle with mathematics and experience a loss of interest. Consequently, there is a recognized and pressing need for change and improvement in mathematics education. Enhancing students' mathematics achievement and interest, particularly among low- achieving students, has emerged as a significant challenge (Amey, 2017; Hiebert & Grouws, 2007). One potential solution to address this challenge is curriculum change, which holds the potential to better cater to students' needs and foster a deeper understanding of mathematics (Boaler, 2016; English, 2008). In light of this, a research study is proposed to investigate the impact of curriculum change on 5th-grade students' performance in mathematics. The research question that will guide this study is as follows: How does curriculum change influence students' performance in 5th-grade mathematics? To address this question, it is necessary to formulate a clearly defined null hypothesis and alternative hypothesis (Witte & Witte, 2017). The null hypothesis states that there is no significant difference in the mean performance of students before and after the curriculum change (H0: μ1 = μ2). Conversely, the alternative hypothesis suggests that there is a significant difference in the mean performance of students before and after the curriculum change (HA: μ1 ≠ μ2). To answer the research question and test the hypotheses, a combination of qualitative and quantitative data need to be collected (Galletta, 2013). Quantitative data, in the form of interval

3 or ratio scales, will be collected to examine the significant difference in the mean performance of 5th-grade students before and after the curriculum change (Witte & Witte, 2017). Additionally, qualitative data will be collected through recordings and open-ended questionnaires to provide supplementary insights and support the quantitative findings (Bandura, 1997; Creswell, 2014). The chosen statistical test for this study is the dependent group t-test (Witte & Witte, 2017). This test is appropriate because it compares the means of two related groups (i.e., the same sample of students before and after the curriculum change) to determine if there is a statistically significant difference between them (Witte & Witte, 2017; Hinkle et al., 2003). Descriptive statistics will be employed to visually represent the mean performance of students before and after the curriculum change (Creswell, 2014). The output of the dependent group t-test will be presented to discuss the significance of the test, with a predetermined significance level of 0.05 (Witte & Witte, 2017; Field, 2013). If the p-value is found to be less than the significance level, the null hypothesis will be rejected, indicating a significant difference in student performance. Conversely, if the p-value exceeds the significance level, the null hypothesis will be retained (Witte & Witte, 2017; Field, 2013). When reporting the findings of the study, the results will be summarized, and their implications will be discussed (Creswell, 2014; Hinkle et al., 2003). Throughout the research process, potential ethical dilemmas may arise, such as issues of informed consent, confidentiality, and safeguarding the well-being of participants (Garet et al., 2001; Johnson et al., 2018). To address these concerns, proper ethical guidelines and protocols will be followed, ensuring that informed consent is obtained from all participants involved in the study (Garet et al., 2001). This will involve providing detailed information about the study's purpose,

4 procedures, and potential risks and benefits to the participants or their guardians, depending on their age. Participants will have the opportunity to ask questions and make an informed decision about their involvement. Confidentiality measures will be implemented to protect the privacy and anonymity of the participants (Johnson et al., 2018). Data collected will be stored securely and accessed only by authorized researchers. Personal identifiers will be removed or coded to ensure that individual participants cannot be identified in any published or presented results. The confidentiality of the participants' responses and information will be upheld throughout the study. Additionally, steps will be taken to ensure the well-being and safety of the participants throughout the research process (Garet et al., 2001). This includes providing a supportive and respectful environment for students, ensuring that they feel comfortable and valued during data collection. Researchers will monitor the emotional well-being of the participants, and any concerns or potential risks will be promptly addressed. In cases where the study may involve sensitive topics or activities, appropriate support systems or resources will be made available to participants. The use of multiple references in this research proposal strengthens its credibility and ensures that the study is grounded in existing literature. Wu et al. (2020) and Boaler (2016) provide insights into the prevalence of conventional teacher-led instruction in elementary mathematics classrooms, highlighting the need for alternative approaches. Yeh et al. (2019) contribute valuable findings from a study conducted in Taiwan, which specifically address the challenges faced by students under this instructional approach.

5 Chapman et al. (2020) and Hiebert & Grouws (2007) shed light on the need to enhance mathematics achievement and interest, particularly among low-achieving students. Their research emphasizes the importance of finding effective strategies to engage and support students who are struggling in mathematics. The references to Boaler (2016) and English (2008) support the idea of curriculum change as a potential solution to address these challenges. They provide insights into the benefits of adopting innovative and student-centered approaches to mathematics education. Amey (2017) contributes to the analysis by emphasizing the importance of closing the STEM skills gap, which aligns with the goal of enhancing students' mathematics achievement. The study explores the sector response to addressing this gap and emphasizes the need for effective strategies in STEM education. Incorporating insights from Amey's research strengthens the proposal's understanding of the broader context and the significance of the proposed study in contributing to STEM education. Witte & Witte (2017) provide guidance on formulating null and alternative hypotheses, as well as selecting the appropriate statistical test. Their work contributes to the methodological rigor of the proposed study. Galletta (2013) emphasizes the importance of collecting both qualitative and quantitative data, highlighting the complementary nature of these data sources. Bandura (1997) and Creswell (2014) offer insights into data collection techniques and analysis, supporting the inclusion of qualitative methods in this study. The choice of the dependent group t-test as the statistical test is supported by Witte & Witte (2017) and Hinkle et al. (2003), who highlight its suitability for comparing means in

6 related groups. This statistical test will allow for a direct comparison of student performance before and after the curriculum change. Field (2013) contributes to the discussion by emphasizing the significance level and interpreting the p-value. By adhering to a predetermined significance level of 0.05, the study will establish a threshold for determining statistical significance. The interpretation of the p-value will enable researchers to make informed decisions regarding the acceptance or rejection of the null hypothesis. When reporting the findings of the study, the results will be summarized, and their implications will be discussed (Creswell, 2014; Hinkle et al., 2003). Throughout the research process, potential ethical dilemmas may arise, such as issues of informed consent, confidentiality, and safeguarding the well-being of participants (Garet et al., 2001; Johnson et al., 2018).
