A comprehensive guided-inquiry approach was used in a combined organic and biochemistry course for prenursing and predietetics students rather than lecture. To assess its effectiveness, exam grades and final course grades of students in three instructional techniques were compared. The three groups were the following: (i) lecture only, (ii)…

Most students enroll in general education introductory nutrition classes because they want to improve their diets in order to lose weight or enhance athletic performance. These nonscience majors are often less interested in learning about the fundamental biochemical principles underlying nutrition or are surprised that this foundational knowledge…

Meta-analyses of active-learning research consistently show that active-learning techniques result in greater student performance than traditional lecture-based courses. However, some individual studies show no effect of active-learning interventions. This may be due to inexperienced implementation of active learning. To minimize the effect of…

It is an established fact that in the United States there is a great need to improve the scientific literacy of undergraduate students, especially those who are nonscience majors. Data presented herein suggest that using simple art concepts can assist nonscience majors in better appreciating scientific facts related to chemistry. However, it is…

Traditional lectures have come under increasing criticism as research indicates lectures may be less effective in achieving learning outcomes than other teaching methods. Student engagement and success can potentially be improved by changing traditional lectures to instructional methods using active learning techniques. Active learning refers to…

Recognition of the value of a scientifically literate citizenry has driven American science education reform since the 1950s. We have seen some improvement in the comprehension of science facts in the past 10-20 years, but far less improvement in Americans' understanding of the nature of science. College science courses are ideal venues for…

Reports on a two-year project in a biology course for nonmajors in which lectures were replaced with guided learning activities and weekly exams designed to help students gain the confidence to be independent learners, especially in science, assume responsibility for their own learning, improve study skills, and make more effective use of class…
