Abstract
This study investigates the effectiveness of teaching technical vocabulary in the English programs of Tripoli’s vocational training institutes, focusing on the Presentation Practice Production (PPP) technique, commonly used for grammar and vocabulary instruction. The research hypothesized that teachers emphasize the presentation stage while neglecting practice and production. Using a quantitative methodology, data were collected through questionnaires and classroom observations involving (40) teachers from various institutes. Results indicated an imbalance in the application of the PPP stages, with teachers prioritizing presentation over practice and production. This gap has contributed to students’ weak technical vocabulary base, underscoring the need for more practice opportunities and communicative activities that help students apply relevant vocabulary in vocational contexts.
