Pictologics (PLS) is a language teaching method which relies on imaginative usage of pictures. The current paper reports the effects of applying this method on enhancing critical thinking ability of the Malaysian students. 69 students (32 boys & 37 girls) in two classes in a public primary school in Penang, Malaysia participated in this study. The experiment covered ten 1-hour sessions which were all audio-recorded and video-taped. The main objective was to engage the students in short conversations in English by using new words that they were learning via PLS. The following qualitative instruments were employed in this study: interviews with the teachers, focus group interviews with the students, a group interview with students' parents, class check-list of the students' behavior during the sessions, photos, and video footages. The findings reveal significant patterns of critical thinking among the students such as recognizing and criticizing assumptions, giving reasons to support a conclusion, incorporating isolated data into a wider framework, and using analogies to solve problems. The author strongly recommends application of adopted PLS techniques to be used either alone, or combined with the other conventional language teaching methods.
