Title:
"Does Physics Teaching Affect Gender-Based Science Anxiety?", M. K. Udo, G. P Ramsey, S. Reynolds-Alpert, and J. V. Mallow, Journal of Science Education and Technology, Vol. 10 No. 3, 2001

Purposes:
This study is to find the factors contributing to anxiety as for a science subject and to investigate influences toward anxiety with semester courses. Then, the possible solutions are discussed to reduce such anxiety.

History:
Quite a few pieces of research have shown that female students are under-represented in the fields of mathematics, physics, and physics-based engineering. On the other hand, a specific anxiety called science anxirty seemed to be a factor for the anxiety for female students. Some research showed that science anxiety and the gender differences begin as early as nine years old. In a general sense, American Association of Physics Teachers noticed students' lack of confidence toward physics classes and offerred a workshop. This research goes to more in-depth to identify the factors of anxiety in terms of science and nonscience anxiety, majors, genders, and so called acute anxiety, which is an expression of "much" and very much" for their anxiety.

Mthod:
The science anxiety questionnaire are taken in all range of physics classes, such as conceptual physics, algebra-based physics, calculus-based physics, and astronomy.

Discussion:
Female students' anxiety is significantly different from male students'. With interactive teaching, nonscience ("trait") anxiety can be largely reduced and acute science anxiety was also improved. Women likely persist in keeping class to the end of semester, but this has more profound insight. Women tend not to drop when the population of female students is mojority. The gender of the teacher affects the anxiety toward students. The same gender tend to ease anxiety.

The reviewed article:
Motivational Patterns Observed in Sixth-Grade Science Classroom, by Okhee Lee and Jere Brophy
Journal of Research in Science Teaching, Vol. 33, No. 3 PP. 303-318 (1996)

Purposes of this article:
To emphasize the value of distinguishing motivation to learn from intrinsic motivation, and of distinguishing general motivational traits from situation-specific motivational states
To value the importance of considering subject-matter content in classroom motivation.

Methods for this study:
The topic is kinetic molecular theory. The curriculum is based on a conceptual change approach in science, which is stimulate students' conceptions and misconceptions. The specific contents are: the nature of matter; three states of matter; thermal expansion; dissolving; melting and freezing; boiling and evaporation, etc. Teachers are asked to encourage students to apply the knowledge they obtaind to explaining other daily phenomena. The class is taught by an interactive way with hands-on experiments, etc. Otherwise, the class is conducted in normal procedure, such as quizzes, reports and activity book. Data are collected and analyzed by two people. They also check the consistency of the data through the process. The study is measured by three motivational levels, which are "behavioral engagement", "cognitive engagement", and "intrinsic motivation." The behavioral engagement is the first step attention. The cognitive engagement is more involved behavior when facing confusion or difficulty to the topic. The intrinsic motivation is enthusiasm in learning. The data from interviews and observations are compiled in terms of the levels of task engagement.

Conclusions and Discussions:
This article discussed the students' behaviors and effective methods to improve their motivation to learn science. There are various methods to be advocated to improve the situation; however, the key is to recognize that there are many of the factors to see students' motivational levels. This also indicates that the multi-aspects of classroom, such as teachers, curriculum, methods, academic tasks, and subject-matter contents, can be the factors to observe. As their conclusion, "Thus, instructional programs or teachers address their intervention strategies more specifically in response to the characteristics of individual students."
