摘要:
The attitudes towards chemistry of the engineering students enrolled in an introductory course at the Polytechnic University of Puerto Rico were explored (n = 115). A mixed methodology was used in an exploratory-oriented research approach. The first stage consisted of the administration of a Likert scale attitudinal survey which was validated during the study's design process. The survey allowed collecting information about the participant's attitudes towards their personal opinion, their perspectives about peer's or relatives' opinion, relevant aspects of the discipline, and difficulty-increasing factors in the chemistry course. The scale internal reliability was measured in a pilot study with a convenience simple, obtaining an acceptable coefficient (Cronbach α = 0.731). Survey results evidenced a mainly neutral attitude towards the chemistry course, not highly negative or highly positive, in contrast with other studies in this field. On the other hand, the normality hypothesis was tested for the scores obtained by participants in the survey. Although the pilot study sample had an approximately normal distribution, the scores in obtained by the participants in the survey failed the normality test criteria. The second stage of the study was accomplished using a case study. Among the survey participants, some students were invited to in-depth interviews to elucidate the reasons why they have certain attitudes towards chemistry. Study time, instructor, motivation, term of study, and course schedule are the factors that interviewees agreed as contributors to success or failure in the chemistry course. Interview's participants emphasized that study time is determinant to pass the class. This methodological approach, quantitative followed by qualitative, was useful in describing the attitudes towards chemistry among university students of engineering.
