Laboratory demonstration, as well as biochemistry lecture, has been used to complement explanation of biochemical processes. The laboratory demonstration is very useful in teaching biochemistry to students who lack background in biology. The experimental model of fibrinolysis described here presents a complex biological reaction in simplified…

In this article students' understanding of trigonometric functions in the context of two college trigonometry courses is investigated. The first course was taught by a professor unaffiliated with the study in a lecture-based course, while the second was taught using an experimental instruction paradigm based on Gray and Tall's (1994) notion of…

Introductory biology courses for pre-professional majors at large universities are usually high-enrollment lectures with associated labs that complement the lecture, but are independently taught and administered. Although web-based instructional formats have become popular alternatives to traditional lectures, it is unknown how these formats…

Two geoscience course sections were provided with lecture content in different formats--one with static text that contained no graphics, the other with a link to a virtual lecture. Follow-up quizzes showed no difference in learning between the two sections, yet attitudes and academic performance differed with gender. (Contains 2 figures and 1…

This hearing discussed how lack of coordination between laboratory exercises and classroom lectures, inadequately trained teachers, languishing facilities, and current high school organization diminish the value these exercises can have or prohibit them all together, and highlighted how a strong hands-on experience can create scientifically…

The modern education system aims at promoting the life quality of individuals, and it requires a philosophical perception and curriculum development approach in line with this aim. In this context, the basic philosophy is to teach people how to learn, have democratic attitudes, convene for teamwork, be able to use information, and think in a…

The first objective of this research was to compare the demographic and academic profiles of introductory sociology students who completed Web-based courses (n = 62) to those who completed traditional lecture-based courses (n = 77). The second objective was to determine the extent to which demographic variables (age, gender, and race), academic…

As multimedia language learning materials become prevalent in foreign and second language classrooms, their design is an important avenue of research in Computer-Assisted Language Learning (CALL). Some argue that the design of the pedagogical materials should be informed by theory such as the interactionist SLA theory, which suggests that input…

This paper discusses how the rise in numbers of non-native English speaking students in British universities has consequences for lecturers trying to be understood by heterogeneous audiences. Although listeners may be invited to ask questions, there are linguistic, psychological, and sociocultural pressures on non-native students that can deter…

Lectures have a place in educational history and even a place in today's classroom, but students must be exposed to more than one style of teaching. After 20 minutes of listening to a lecture, most students reach a saturation point. To realize their maximum potential, students must do more than just listen in the classroom. They must engage in…

Two studies compared strategies used to improve listening skills in business communication settings. The first study analyzed the effect of discussion length and incentive level on the ability of 347 business communication students placed in differing discussion and incentive groups to identify main points in 22 short, recorded dialogs. Results…

A study was conducted to compare the effectiveness of using the television lecture series "Introducing Biology" to traditional lecture techniques in a college-level Animal Biology course. The interest levels and subject course mastery of three groups of students were compared: (1) a control group who attended two 50-minute lectures per week; (2)…

College students were found to have a significantly more positive attitude toward a teacher who was nonverbally active and expressive rather than toward a teacher who was "still" and made no intentional nonverbal behavior. (SE)

The general conclusion of the study is that a lecture-demonstration in a minicourse format can be used with a group that has been pre-selected with regard to occupational interest. This combination of methods provides information concisely and allows "hands-on" learning reinforcement as well. (MW)

The purpose of this study was to compare the knowledge about art acquired by students who went on site visits with that of students who experienced only the lecture method of teaching. A study was conducted at Boricua College (New York) with two groups of 25 students each, one participating as a control and one as an experimental group. The…
