To determine which statement most strengthens the researchers' reasoning, we need to examine how each option relates to the argument that the interactive features of electronic textbooks do not enhance reading comprehension because reading comprehension relies on text engagement and critical thinking. Let's analyze each option:
A. Students who use electronic textbooks report higher levels of satisfaction with their learning materials than those using traditional textbooks.
This option highlights student satisfaction, which is not directly related to reading comprehension scores. High satisfaction does not necessarily imply better comprehension, so this option does not strengthen the researchers' reasoning.
B. Schools that have introduced electronic textbooks have also invested in teacher training to integrate technology effectively into their curriculum.
This option focuses on teacher training and effective integration of technology. While important for overall educational quality, it does not directly address the core issue of whether electronic textbooks improve reading comprehension. Therefore, it does not strengthen the researchers' reasoning.
C. Research has shown that the additional features of electronic textbooks, such as multimedia and hyperlinks, often distract students from the main text, reducing the depth of their engagement with the content.
This option directly supports the researchers' contention by providing evidence that the interactive features of electronic textbooks can distract students from engaging deeply with the text. This distraction can reduce critical thinking and text engagement, which are essential for reading comprehension. Thus, this option strongly strengthens the researchers' reasoning.D. Many students using electronic textbooks perform better on interactive assessments that are integrated into the electronic textbook platform.
This option indicates better performance on interactive assessments but does not address reading comprehension directly. The argument is specifically about reading comprehension, not overall performance on varied types of assessments. Therefore, this option does not strengthen the researchers' reasoning regarding reading comprehension.
E. The cost of electronic textbooks is significantly lower than that of traditional textbooks, making them a more economical option for schools.
This option deals with the cost-effectiveness of electronic textbooks, which is not relevant to the argument about reading comprehension. While important from a financial perspective, it does not strengthen the researchers' reasoning about the impact on reading comprehension.
Therefore, the statement that most strengthens the researchers' reasoning is:
Answer: C
