Introduction
Teaching reading at CEFR B2 level involves more than helping students understand what a text says. Students must also analyze information, infer meaning, evaluate ideas, recognize relationships between arguments, and identify the writer’s purpose and tone. For matriculation students preparing for further studies, these skills are particularly important because academic success depends on their ability to interpret information and respond to it independently.
As an English language lecturer, I have observed that some students can understand individual sentences but struggle to grasp the overall meaning of a passage. They may focus excessively on unfamiliar vocabulary, search for matching words in a question, or select an answer simply because it contains a familiar phrase from the text. In such cases, students recognise words without fully understanding the message those words convey. This classroom experience prompted me to investigate a recurring difficulty among my M2T2 students: distinguishing main ideas from supporting details in CEFR B2 reading tasks. Through a Professional Learning Community (PLC), I collaborated with colleagues to identify the learning difficulty, redesign the lesson, observe its implementation, reflect on the evidence, and refine our teaching approach.
I designed the intervention around the principle that teachers should explicitly teach reading comprehension strategies rather than expect students to develop them independently. Langenburg (2000) highlighted the value of explicit comprehension instruction, graphic organisers, questioning, and combining multiple strategies to support reading comprehension.
Identifying the Reading Difficulties
I worked with 22 M2T2 students enrolled in a CEFR B2-level English course. A diagnostic reading assessment and classroom observations revealed difficulties in identifying main ideas, distinguishing supporting details, and applying appropriate reading strategies. The diagnostic results showed that only 6 of the 22 students correctly identified main ideas, representing 27.3% of the class. The remaining 16 students (72.7%) struggled to distinguish central ideas from supporting details. The problem was particularly evident in matching-headings tasks, where 18 students (81.8%) selected incorrect answers. In ‘True/False’ task, 14 students (63.6%) misinterpreted the information. My classroom observations also showed that 17 students (77.3%) relied on word-by-word reading, while only 5 students (22.7%) demonstrated the use of skimming strategies
The diagnostic findings revealed that some students struggled to distinguish a paragraph’s central message from its supporting details. For example, when reading a paragraph about the environmental effects of plastic pollution, some students selected a heading related to “Types of Plastic Materials” because the paragraph mentioned several types of plastic. Although they recognised familiar vocabulary, they overlooked the paragraph’s main message. Similarly, when reading a passage about the importance of recycling, some students identified “Recycling reduces landfill waste” as the main idea, even though it represented only one supporting detail.
Strategy 1: Making Reading Strategies Visible
Our PLC team collaboratively planned a lesson using the Focus–Implement–Share (FIS) approach. During the Focus stage, we identified students’ difficulties and discussed how explicit modelling could help them distinguish main ideas from supporting details. Drawing on Langenburg’s (2000) emphasis on explicit comprehension strategy instruction, we made the reasoning processes involved in constructing meaning more visible to students.
During implementation, I used think-aloud modelling to demonstrate how an experienced reader approaches a paragraph. Rather than simply providing the correct answers, I verbalised my thought processes by asking questions such as:
- What is this paragraph mainly about?
- Which idea connects the information in the paragraph?
- Which sentence expresses the overall message?
- Which information provides an example, explanation, or piece of evidence?
I also introduced a clear distinction between a main idea and a supporting detail:
- Main idea: What is the paragraph mainly about?
- Supporting detail: What information explains, illustrates, or develops the main idea?
During guided practice, students worked in pairs and small groups, using graphic organisers to identify the main idea and distinguish it from supporting details. Instead of asking only, “What is the answer?” I encouraged students to explain their reasoning by asking, “Why do you think this is the answer?” and “What evidence in the text supports your choice?” Through this questioning approach, I helped students justify their answers using textual evidence rather than rely on familiar keywords or guesswork.
Lesson Observation and PLC Reflection
Students engaged with the activities, but active participation did not always indicate independent understanding. During group work, some students contributed more frequently, while others relied on stronger classmates. Consequently, some groups completed their tasks successfully even though individual members remained uncertain about the reading process.
Strategy 2: Strengthening Independent Application
Following reflection, we incorporated systematic think-aloud modelling, graphic organisers, sentence starters, targeted questioning, and individual justification tasks into the revised lesson. I explicitly modelled skimming and scanning and gave students opportunities to practise these strategies. This approach allowed transferring the strategies beyond the initial lesson, rather than simply reproducing answers or relying on their familiarity with the original text. Langenburg (2000) reported that comprehension instruction could benefit from a combination of strategies, including graphic organisers, questioning, cooperative learning, and summarisation. Hence, our revised approach reflected the value of combining comprehension strategies rather than teaching them as isolated techniques.
Observed Changes in Student Responses
The graphic organisers appeared particularly helpful in supporting students as they distinguished a central idea from the information that explained it. I observed students beginning to consider how ideas connected within a paragraph instead of viewing the paragraph as a collection of separate sentences. I also made my questioning more purposeful. I used prompts such as “Which sentence communicates the main point?”, “Why is this a supporting detail rather than the main idea?” and “What evidence from the text supports your answer?” These questions encouraged students to explain their reasoning and gave them opportunities to examine whether textual evidence supported their choices. However, I interpret these observations cautiously. Although I used a new reading text to examine strategy transfer, I do not have numerical post-assessment results to demonstrate the extent of improvement. Therefore, the observed changes suggest progress in students’ classroom engagement with reading strategies, but they do not establish a measurable increase in reading achievement.
This distinction matters because participation, confidence in explaining an answer, and demonstrated reading comprehension represent related but different outcomes. To determine more precisely whether students improved their accuracy in identifying main ideas and interpreting textual information, I would need to assess them again using comparable reading tasks.
Conclusion
The diagnostic assessment revealed students’ difficulties in distinguishing main ideas from supporting details, while my classroom observations highlighted their reliance on word-by-word reading and familiar keywords. These findings guided our use of explicit modelling, guided practice, graphic organisers, strategic questioning, and individual justification tasks.
I found the observed changes during the second implementation encouraging, particularly students’ increased willingness to explain their answers and refer to the overall meaning of a paragraph. Nevertheless, because I do not have numerical follow-up assessment results, I regard these observations as preliminary classroom evidence rather than conclusive proof of improved reading achievement.
