The affective filter describes a mental barrier shaped by emotions that can block language input from being processed. When a learner is relaxed, motivated, and confident, the filter is low, and new language input is more readily absorbed and learned. When anxiety is high or motivation is low, the filter rises, making it harder for input to get through and slow down acquisition. So the statement that high anxiety or low motivation raises the affective filter and hinders intake captures this dynamic most accurately. The idea that the filter has no effect on input conflicts with the theory, and saying it only affects pronunciation is too narrow since emotional state can influence listening, reading, and overall learning. Likewise, suggesting a low filter hinders learning would be the opposite of how this concept works.

Culturally sustaining pedagogy in ESL classrooms treats students' languages and cultures as essential assets in learning. It centers and preserves their linguistic and cultural practices within the curriculum, using these practices to make content meaningful and accessible. When instruction draws on students’ home languages, literacies, and cultural backgrounds, learners see themselves reflected in what they study, which strengthens identity and boosts motivation. This sense of belonging supports deeper engagement with material and steady academic progress because students can connect new concepts to familiar experiences and ways of thinking. In practice, this means including culturally relevant texts and media, allowing responses in students’ home languages when appropriate, and designing assignments that leverage students’ community knowledge. It also involves creating opportunities for students to share their cultures and languages in the classroom, and using translanguaging as a flexible tool to access and construct knowledge. Other approaches that push for rapid fluency without honoring culture, or that focus on a single dominant culture, or that separate language maintenance from content, miss the chance to build a truly inclusive, motivating, and effective learning environment.

Understanding an unfamiliar word often comes from looking at its parts: prefixes, roots, and suffixes. When a teacher prompts a learner to examine these morphemes, they guide the student to deduce meaning by analyzing how the word is built. For example, in a word like unhappy, breaking it down into un- (not) + happy (happy) shows that the whole word means not happy. Adding a suffix like -ness to happiness yields a noun meaning the state of being happy, and similar patterns apply to many other words. This approach provides a reliable, portable way to unlock meaning directly from word structure, especially for readers encountering long or complex terms. While context and sentence structure can help, focusing on morphemes gives a direct route to understanding the word itself.

Pre-teaching discipline-specific vocabulary helps bridging-level learners access the lecture content by reducing language barriers before they encounter the ideas. When students know the key terms and their meanings, they can follow explanations, see relationships, and grasp procedures more quickly during the lecture, which is especially important in a one-to-one laptop setting where they can access glossaries and quick references on the spot. This approach lowers cognitive load, builds relevant background knowledge, and lets learners focus on understanding concepts rather than constantly decoding jargon. In contrast, plain slides without visuals provide less multimodal support, encouraging overload; asking students to skip note-taking removes a proven strategy for processing and retaining information; and requiring memorization before watching places an unrealistic demand that doesn’t support real-time comprehension.
