**Abstract:**

This mixed methods study examined preservice secondary mathematics teachers’ perceptions of a blogging activity used as a supportive teaching-learning tool in a college Euclidean Geometry course. The effect of a 12-week blogging activity that was a standard component of a college Euclidean Geometry course offered for preservice secondary mathematics teachers, during the fall semester of 2011 in a university in the western United States was investigated in this study. The blog can be visited at http://edsc353fall2011.wordpress.com/

Participants’ perceptions were measured by two dependent variables: (1) participants’ attitudes toward the blogging activity in the college Euclidean Geometry course – measured by calculating the median response to the 16 Likert-type scale items measured on a six-point scale; and (2) participants’ perceived effectiveness of the blog for the learning of Euclidean Geometry– measured by calculating the median response of another 18 Likert-type scale items measured on a six-point scale. Participants’ cumulative quiz scores attained on eight in-class quizzes was used as a dependent variable to see whether or not there were relationships between the quiz total and either of the other dependent variables. There were two independent variables: (1) participants’ gender – a categorical variable with two categories: male and female; and (2) participants’ self-reported total time spent per week on the Internet – these values were divided into two categories using a median split.

Quantitative data was collected using an instrument developed by the researcher. Validity and reliability of the instrument were measured through appropriate procedures and were found to be authentic and consistent. Qualitative data was collected using two open-ended questions on the survey as well as from the students’ postings to the online discussion board on the blog. The quantitative and qualitative data were analyzed separately using SPSS-PASW for Windows and MAXQDA, respectively.

Participants’ overall attitude scores toward the blogging activity showed a mean, median, and mode of 4.18, 4.0, and 4.0 respectively with a standard deviation of 0.95, suggesting that participants’ typical response indicated strong agreement that they had a positive attitude toward the blogging activity. Similarly for perceived effectiveness, the mean, median, mode of 4.13, 4.0, and 4.0, respectively indicated that the participants tended to strongly agree that the blogging activity was an effective means of teaching and learning Euclidean Geometry.

Due to the ordinal nature of the first two dependent variables that measure participants’ attitudes toward and perceived effectiveness of the blogging activity respectively, the non-parametric Wilcoxon-Mann-Whitney U test was carried out on median attitudes and median perceived effectiveness scores separately to determine if differences exist on these data across participants’ gender and self-reported time on the Internet.

The study did not indicate any significant difference in the participants’ median attitude scores (*N* = 28, *U* = 68.0, *p *> .05) toward the blogging activity in a college Euclidean Geometry course based on their gender. Also, no significant difference was indicated in the participants’ median perceived effectiveness scores (*N* = 28, *U* = 94.50, *p*> .05) of the blogging activity for the learning of Euclidean Geometry in terms of their gender.

Similarly, the study did not indicate any significant difference in the participants’ median attitude scores (*N* = 28, *U* = 61.50, *p*> .05) toward the blogging activity in a college Euclidean Geometry course with regard to their self-reported total time spent per week on the Internet. However, a significant difference was indicated in the participants’ median perceived effectiveness scores (*N* = 28, *U* = 53.00, *p* <.05) of the blogging activity for the learning of Euclidean Geometry with regard to their self-reported total time spent per week on the Internet.

Moreover, the study did not indicate a significant correlation (*N* = 28, *r _{s}* = -0.145,

*p*>.05) between the participants cumulative quiz scores and their median attitude scores toward the blogging activity. Similarly, the study did not indicate a significant correlation (

*N*= 28,

*r*= -0.232,

_{s}*p*>.05) between the participants cumulative quiz scores and their median perceived effectiveness scores toward the blogging activity.

Furthermore, qualitative analyses of the survey data revealed that the preservice mathematics teachers reported numerous advantages of the blogging activity as a supportive tool in the college Euclidean Geometry course, despite the limitations of the free blog service being used. Some minor disadvantages or problems of using a blog as a supportive tool in the college Euclidean Geometry course were, also, reported by participants.

Finally, this study analyzed the major trends that emerged in an unguided online discussion board on the blog. Interestingly, this component of the study revealed approximately twenty major themes raised by preservice secondary mathematics teachers. Although, the participants’ discussion did not focus in any specific direction, interestingly, most of the topics were related to the improvement of learning styles and professional development, topics that are often not discussed in the classroom.

The study revealed that participants considered the blog to be an open and public forum where they can discuss issues and discussion topics of interest to them and present their personal views and experiences without hesitation. This has the potential to allow mathematics students and teachers to build and join in many virtual platforms on blogs where they can share their voices and perspectives in a public forum.

In the conclusions, the findings of this study suggest that blogs and other Web 2.0 technologies could provide an important avenue for fostering the teaching and learning of mathematics in today’s technologically advanced society. Most teachers from the middle school to the college levels have enough computing knowledge to create and maintain academic or personal blogs on a suitable server free of cost. Those who don’t could be trained to do so in a few hours. Thus, the educators need to capitalize on the proliferation of technology and the fascination of students with the interactive features of emerging Web 2.0 applications that can be used wirelessly.
