EPISTEMOLOGICAL BELIEFS IN SCIENCE: AN EXPLORATORY STUDY OF LEBANESE UNIVERSITY STUDENTS’ EPISTEMOLOGIES

Beliefs about the nature of knowledge and knowing have been investigated extensively in educational and developmental psychology research. Hofer??s framework on personal epistemology is adopted in the present study for assessing Lebanese university students?? epistemologies of science. Participants were 213 students in their first year of science-related studies at a private university in Beirut. Two instruments were used for data collection: The science-focused epistemological beliefs questionnaire (Hofer, 2000) and an 8-item instrument adapted from the modified version of the ??Views on Science?CTechnology?CSociety?? (Dogan & Abd-El-Khalick, 2008), and an additional item developed by the authors. Thirty students were purposively selected for completing the second instrument followed by a semi-structured interview. Data analysis yielded the following assertions regarding students?? epistemologies of science: (1) Scientific knowledge is liable to change; (2) the source of scientists?? knowledge is inherent to human??s construction, whereas the source of personal knowledge is independent from human subjectivity and based on external authority; (3) scientific knowledge is proven and validated through the concerted effort of scientists; and (4) absolute truth cannot be attained because of the lack of means to access knowledge. Findings highlighted the need to foster an academic culture that promotes students?? epistemologies and explicitly addresses the nature and processes of science in curricula and instruction.     

Fathers' Early Contributions to Children's Language Development in Families from Low-income Rural Communities

This study utilized a large sample of two-parent families from low-income rural communities to examine the contributions of father education and vocabulary, during picture book interactions with their infants at 6 months of age, to children's subsequent communication development at 15 months and expressive language development at 36 months. After controlling for family demographics, child characteristics, as well as mother education and vocabulary, father education and father vocabulary during the picture-book task were related to more advanced language development at both 15 and 36 months of age. Only mother education, but not vocabulary during book-reading was related to children's later language. These findings support the growing evidence on the importance of fathers in understanding children's early communication and language development.
