1.0 INTRODUCTION

1.1 BACKGROUND OF THE STUDY

The educational landscape in Ghana, particularly in the field of physics education, is characterized by various challenges that impact the effectiveness of teaching and learning. One critical aspect of this landscape is the assessment practices employed by physics teachers, which plays a significant role in shaping students learning outcomes (Bekoe et al., 2013). This meta-analysis aims at exploring the application of the Depth of Knowledge (DOK) framework in the assessment practices of physics teachers in Ghana, providing insights into how these practices influence students engagement and understanding.

The DOK framework, developed by Norman Webb, categorizes tasks according to the complexity of thinking required to complete them. It consists of four levels namely; Recall and Reproduction, skills and concepts, strategic thinking, extended thinking (Mulhall et al., 2008).

Understanding and implementing these levels in assessment practices is crucial for fostering higher-order thinking skills among students, particularly in a complex subject as physics.

1.2 CURRENT STATE OF PHYSICS EDUCATION IN GHANA

Research indicates that many physics teachers in Ghana, primarily utilize lower-order assessment methods that focus on recall and basic comprehension, often neglecting higher-order thinking skills necessary for deeper understanding and application of physics concepts. This reliance on traditional assessment methods can lead to superficial learning, where students memorize information without truly, grasping the underlying principles (McDermot, 2001).

Moreover, the lack of professional development opportunities for teachers to enhance their understanding of the DOK framework contributes to the persistence of this challenge. Teachers may not be adequately trained to design assessments that reflect higher DOK levels, which can hinder their ability to promote critical thinking and problem-solving skills among students (McDermot, 2001)..

1.3 IMPLICATIONS FOR STUDENT LEARNING

The implications of inadequate assessment practices are significant. Students may struggle to apply physics concepts in real-world situations, limiting their preparedness for advanced studies and careers in science and technology. Furthermore, the educational context in Ghana, including cultural attitudes towards teaching and assessment, may influence how physics teachers approach their assessment practices, necessitating a comprehensive examination of these factors (Okoronka, 2014).

This meta-analysis seeks to synthesize existing research on the assessment practices of physics teachers in Ghana, focusing on the application of the DOK framework. By identifying current practices and their implications for student learning, the study aims at providing recommendations for improving physics education through enhanced assessment strategies that promote higher-order thinking.

1.5 PROBLEM STATEMENT

The thesis topic "Examining the Rule of Depth of Knowledge of Physics Teachers' Assessment Practices in Ghana" addresses a critical gap in the understanding of how physics teachers in Ghana implement assessment practices that align with the Depth of Knowledge (DOK) framework (McDermot, 2001). The DOK framework, developed by Norman Webb, categorizes tasks according to the complexity of thinking required. This study aims at investigating the extent to which physics teachers utilize various levels of DOK in their assessment practices and how these practices impact students learning results (Mulhall et al., 2008).

1.5.1 Inadequate Understanding of DOK Levels

Many physics teachers in Ghana may lack a comprehensive understanding of the DOK framework and its application in assessment. This gap can lead to assessments that do not adequately measure students' higher-order thinking skills, which are essential for mastering physics concepts (Eshun and Korwu, 2017).

1.5.2 Limited Assessment Practices

Current assessment practices among physics teachers may predominantly focus on lower-order thinking skills, such as recall and basic comprehension, rather than encouraging critical thinking and problem-solving abilities. This limitation therefore hinders students' ability to apply physics concepts in real-world situations (Angell et al, 2004 ).

1.5.3 Impact on Student Learning

The reliance on lower DOK levels in assessments may contribute to superficial learning, where students memorize information without developing a deeper understanding of the subject matter. This issue is most common in a subject like physics, where conceptual understanding is crucial for success in advanced studies.

1.5.4 Professional Development Needs

There is a pressing need for targeted professional development programs that equip physics teachers with the skills and knowledge necessary to design assessments that reflect higher DOK levels. Without such training, teachers may continue to rely on outdated assessment methods that do not support effective learning.

This review synthesizes relevant literature that addresses the current state of assessment practices among physics teachers, the application of the DOK framework, and the implications for educational improvement.

2.1 Understanding the Depth of Knowledge Framework

Research indicates that effective assessment practices should encompass a range of DOK levels to promote higher-order thinking skills among students. However, many educational stakeholders including physics teachers in Ghana, often focus predominantly on lower DOK levels, which limits students' critical thinking and problem-solving abilities (Eshun and Appiah, 2017).

2.2 Current Assessment Practices in Physics Education

Studies have shown that physics teachers in Ghana frequently employ traditional assessment methods that prioritize rote memorization and basic comprehension over higher-order thinking. For instance, a study conducted in various educational settings revealed that assessments often consist of multiple-choice questions and short-answer formats that do not adequately challenge students to apply their knowledge in real-world contexts. This reliance on lower thinking-order assessments hinders students' ability to engage deeply with physics concepts (Eshun and Appiah, 2017).

2.3 Challenges in Implementing Higher DOK Assessments

Research highlights several challenges that physics teachers face in implementing assessments aligned with higher DOK levels. These challenges include a lack of professional development opportunities, insufficient resources, and limited understanding of how to design assessments that promote critical thinking. Additionally, cultural attitudes towards education and assessment in Ghana may influence teachers' willingness to adopt innovative assessment practices.
