Topic 4.1.6: How Do I Determine Instructional Implications?

How Do I Determine Instructional Implications?

Nancy Fichtman Dana


University of Florida

As teachers engage in the process of action research, the systematic, intentional study of one's practice becomes a natural, never-ending part of teaching (Dana & Yendol-Silva, 2003). Teachers formulate a question, collect data to gain insights into that question, and make changes in their instructional practice based on insights gained from the data. These changes to instructional practice necessitate that more data be collected through progress monitoring and subsequently analyzed to determine the effectiveness of the implemented instructional changes. Insights gained from progress monitoring data inevitably lead to new questions, and the process of data collection and data analysis begins again.

While the process of action research is cyclical and never-ending, at times, it is critical to step outside of the process and reflect on what has been learned within one cycle. Momentarily stepping outside of the cycle to reflect on the process as a whole enables teachers to determine the instructional implications of their research.

One way to step outside of the cycle to think about the instructional implications of the research is by writing. In fact, noted educational ethnographer, Harry Wolcott (1990) goes so far as to state that writing and thinking are synonymous:

The conventional wisdom is that writing reflects thinking. I am drawn to a different position: Writing is thinking (p. 21).

Referring specifically to the process of teacher inquiry, Mills (2003) further states that there is great value in writing up research because:

. . .the very process of writing requires the writer to clarify meaning – choose words carefully, thoughtfully describe that which is experienced or seen, reflect on experiences, and refine phrasing when putting words on a page. You may learn something very important about your students and their learning – something you may have missed had you not considered your words on the page – as you formally write about your research (p. 164).

For this reason, it is recommend that every teacher researcher write as an extension of data analysis and as a wonderful way to extend learning.



Why Should a Teacher Write?

Unfortunately, while writing is a terrific mechanism for clarifying thinking as one summarizes what has been learned and gives learning a form that is able to shared with others, writing is not a part of a teacher's daily work, and it takes a great deal of time. Mills (2003) suggests challenging the time constraint by making writing a part of one's professional life and a responsibility through capturing the minutes and hours where they fall – before school, after school, preparation periods, cancelled faculty meetings, failed parent conferences, professional development days, and sometimes, when all else fails, personal time to get writing done.

If one can get past the time constraint and the resistance to engage in an activity that Wolcott describes at its best as "always challenging and sometimes satisfying" (p. 12), the times that it is satisfying will outweigh all the difficulty and frustration inherent in writing. The writing process will take an individual's inquiry to a new level. Mills (2003) suggests sound reasons for writing. Here are his four most compelling reasons to write:


  1. Clarification – Writing your research requires clarity and accuracy of expression. Writing about your research activities encourages thought and reflection, and perhaps creates new questions that are resolved, which shape and complete your research.

  2. Empowerment – Reflecting on your practices through writing will empower you to continue to challenge the status quo and be an advocate for your students.

  3. Generative – Writing is a generative activity that culminates in a product, something tangible that you can share with colleagues, supervisors, and parents.

  4. Accomplishment – Writing up your research will provide you with a sense of accomplishment. It is both humbling and exciting when colleagues read your work and compliment you on your accomplishments! (p. 164 – 165).

What Might the Writing Look Like?

Inquiry write-ups come in all sorts of flavors and a variety of sizes. Some teacher researchers write up their work to be published in a book, monograph, or journal. Some teacher researchers write up their work to inform district administration. Some teacher researchers write up their work for policy-makers. Some teacher researchers write up their work in order to be able to share it with other colleagues at their school. Whatever the "flavor" or "size" of the inquiry write-up, it should be detailed enough to be meaningful and useful to other teachers so others can benefit from the work. A good recipe for an inquiry write-up contains the following five ingredients:



  1. Including or providing Background Information/Purpose of Inquiry

  2. Sharing the Design of Your Inquiry

  3. Stating What has been Learned and Supporting Your Statements with Data

  4. Concluding with Thoughts

  5. Citing References

In the remainder of this article, each of these essential ingredients is further described and illustrated through the work of high-school chemistry teacher Steve Bergin (2007), who conducted an action research project in his class entitled, "A Demo-A-Day in High School Chemistry."

Background Information/Purpose of Inquiry

A strong way to begin writing is to provide background information. Sharing the context, motivating factor(s) for this particular study, connection(s) to other's thinking about the topic of the inquiry, and process(es) utilized to gain insights into a particular wondering provide a foundation for the audience to understand the work and to make judgments as to its transferability to their own teaching situation. Note how Steve accomplished this in his writing below:



As a high school chemistry teacher, I have been constantly distressed by the apparent fright that accompanies the typical high school student's enrollment in my introductory chemistry course. What is it about chemistry that makes it so seemingly "impossible" for so many students? Sometimes it feels as if a student's belief that he or she will fail at chemistry becomes a self-fulfilling prophecy. My personal study of chemistry came with no such fears. What was it about my experiences that got me excited and even passionate about this subject? Thinking back to my high school and college chemistry courses, the use of demonstrations was the one thing that most enthralled me. I can still remember most of the demonstrations that I saw as a high school student. These "magic tricks" were one of the reasons I decided to major in chemistry in college. The anticipation of being able to perform them one day in a class room of my own was a key motivating factor for me in becoming a high school chemistry teacher.

Looking into the research on lecture demonstrations yielded some very interesting discoveries. I found that many educators are apprehensive about performing demonstrations for a number of reasons. Some believe that demonstrations are too costly for their science department. Others feel that demonstrations are too exhausting to execute or too time-consuming to prepare. The most surprising find was that research on the connections between lecture demonstrations and student achievement is so limited that educators don't feel like an extensive use of such demonstrations is warranted (Meyer, Schmidt, Nozawa, Panee, & Kisler, 2003). However, the pedagogical reasons for performing demonstrations given by Meyer, et al. (2003) are much more numerous. Demonstrations provide students with learning opportunities that would be otherwise impossible. Doing demonstrations allows students to visualize experiences that would not be feasible in a laboratory setting. For example, some demonstrations might be too dangerous, or too costly, to perform as a large-scale laboratory activity. Another reason for performing demonstrations is that it allows students to "see" a chemical reaction in a way that textbook graphics cannot depict. These demonstrations provide a visual framework for abstract concepts, facilitating the learning and understanding of this fundamental and central science discipline. "By using demonstrations in appropriate and thoughtful ways, teachers will teach better, inspire more, and increase the likelihood that chemistry will contribute to a better future for all of us." (Meyer, et al, 2003)

I have been using lecture demonstrations consistently during my first three years of teaching, but I find that my students still have negative feelings towards the subject of chemistry that I hold so dear. How can I better utilize demonstrations in a way that empowers my students' learning of high school chemistry? This was the question that fueled my personal inquiry into this matter.


Sharing the Design of the Inquiry

A key feature that sets inquiry apart from the daily reflection that teachers engage in is that it is conducted in a systematic, intentional way. Hence, sharing the system (what was done), as well as the intentions (how was it done – data collection and analysis) is important. In the next excerpt, notice how Steve discusses his instructional plan for this inquiry and the ways he collected data.



I teach a total of seventy-one students dispersed among three general level high school chemistry classes. In seeking to answer my wonderings, I developed a month long curriculum that consisted of a discrepant event demonstration for each and every time my class met. Since my school is on a block schedule, my classes meet three times a week. A total of thirteen demonstrations were used in the teaching of this unit. These demonstrations explored the topics of acid and base chemistry, dynamic equilibrium, and catalysis. Most of the demonstrations came from handouts I had received from the chemical supply company, Flinn Scientific, while attending sessions at several National Science Teacher Association conferences. After the unit was over and all assessments were complete, the students began preparing demonstrations to perform for third, fourth, and fifth graders at an elementary school in our district. The instructional goals of these "shows" were for the high school students to gain a deeper understanding of the chemistry that was taking place in their demonstrations, and for the elementary students to understand the difference between a chemical and physical change.

My students were quizzed and tested prior to the Demo-A-Day unit to gauge their current levels of achievement in my chemistry class. During the unit, students videotaped me performing each of the thirteen demonstrations. Students were then quizzed and tested on the content of the Demo-A-Day unit. During these assessments, the videotapes were played back for the students to help stimulate their thought processes and remind them of what they had previously observed in class. Following this assessment, I then placed my students in groups of four. Each group selected one of the thirteen demonstrations that they had previously observed in the Demo-A-Day unit. Groups then prepared the necessary solutions, planned a script, and practiced their demonstrations in front of their peers. Students were asked to complete a demonstration show planning form, which I collected and graded. In this form, students had to describe all aspects of their demonstration. This included the chemicals they would need to use, the script they would use as they were performing the demonstration for the elementary school students, and the safety hazards of their specific demonstration. Groups were then videotaped as they performed their demonstration shows for the elementary students. Following the show, students were asked to write a reflective paper on both the Demo-A-Day unit and the demonstration show. Students also completed a Likert attitude assessment form. This consisted of ten items measuring student feelings toward chemistry, the Demo-A-Day unit, and the demonstration show.

During this entire unit, I reflected in my journal after each of the demonstrations was performed, and as I reviewed the videotapes. I then compared student grades before and after the unit, and used graphic organizers to compile my data. Student reflections were graded, and data obtained from the Likert attitude assessment was graphically represented on pie charts.


Stating the Learning and Supporting the Statements with Data

With detailed knowledge of the "how" of the inquiry, the audience is now ready to understand Steve's findings, which he presents as "claims." As Steve engaged in the process of writing this report of his inquiry, he clarified his thinking as he chose words and phrases to carefully reflect and represent his findings in this form. In the absence of the process of writing it up, Steve would not have taken his work to this organizational level and not realized the extent of his own learning, and the many instructional implications of his work.

A number of claims can be made from this study. The first is that there appeared to be no correlation between the use of teacher demonstrations and achievement in my chemistry class. This was observed when grades before and after the demonstration unit were compared.

Figure 2: Test Grades before and after the Demonstration Unit

After careful examination of these graphs, it is apparent that no significant changes were observed in the achievement on my tests or quizzes in my class. While the average quiz grade increased, the test grades actually slightly decreased. This indicates to me that a number of factors need to be taken into consideration when assessing my students. First, I do not think that these grades can be directly attributed to the use of the demonstrations every day. They may be due to the amount of laboratory experiences in this unit, or to a more complex nature of the topics that were addressed in this unit. Second, perhaps students were not performing to their full potential due to a lack of motivation that often accompanies the start of the third quarter of the school year. Regardless of the causes, future research would need to be done to make claims about the use of demonstrations and the achievement in chemistry class.

My second claim from this inquiry is that students believe that both the Demo-A-Day unit and the demonstration show actually increased their understanding of chemistry. Regardless of the lack of significant improvement in test and quiz scores, students do feel like they learned something. I think that this could lead to better attitudes in my class. In turn, this might potentially challenge the self-fulfilling prophecy that "chemistry is impossible" that so many of my students seem to carry into class. The Likert attitude assessment, in particular, revealed this dimension of increased student efficacy.

Figure 4: Likert Attitude Assessment of Demonstration Show

Videotape evidence and examinations of student reflections revealed that students truly enjoyed the Demo-A-Day unit and the demonstration show. This leads to my third claim. The process used in this inquiry was enjoyable to both the high school students and to the elementary students who observed the demonstration show. High school students were heard in the videotapes enthusiastically expressing comments such as, "That's amazing," "I loved that," and "That's what I am talking about!" In addition to these statements, the amount of engagement that I observed in the videotapes leads me to believe that the students were truly enjoying the demonstrations as a welcome change from a traditional lecture style. The elementary students also expressed their excitement. They, too, made statements following the demonstration show, such as, "Cool!" "Awesome!" and "That's neat." One elementary student even said, "I'm going to be a chemical scientist one day." Another asked, "Will I get to do that in high school?" One elementary teacher wrote, "I just wanted to take a minute to thank you, on behalf of the third grade team, for the awesome chemistry demonstration show last week. Our third graders really enjoyed the show and learned 'and saw' real life chemical reactions." Based on these findings, claims can be made that student attitudes towards this unit and culminating show were very positive.



Providing Concluding Thoughts and References

When reading a good mystery, one expects that the conclusion of the book will provide answers to solve the mystery. Similarly, when nearing the end of writing up the work to share it, it may be conceived that the concluding thoughts are answers to the initial questions posed by the inquiry study. This might be the case sometimes. However, just as often, concluding thoughts do not answer the initial research question, but generate additional questions and further areas for inquiry.

The work of a teacher researcher is never quite finished as teacher research is not a linear project that is completed at one point in time and is over. Rather, teacher inquiry is a continual cycle that all educators spiral through during their professional lifetimes -- a professional positioning or stance, owned by the teacher where questioning, systematically studying, and subsequently improving one's own practice becomes a necessary and natural part of a teacher's work.

Therefore, it is difficult to conceive of how to finish a piece of writing when the work of a teacher researcher is never done. Many teacher inquirers finish their work by reflecting in general on the specific inquiry just completed, generating directions for the future, stating further wonderings, and listing references that were important to their work. A listing of the most valuable references they came across as they engaged in their research is important so that other teachers may refer to these references as they think about their own practice in relationship to a particular inquiry. This article ends with the concluding passage from Steven's paper. Upon reading it, it is important to note how he utilized these four techniques (reflecting in general on the specific inquiry just completed, generating directions for the future, stating further wonderings, and listing important references) to bring closure to his written work ( ):

Although no significant claims could be made regarding the achievement of my students being a result of daily teacher demonstrations, I feel confident concluding that the Demo-A-Day unit, coupled with the student-facilitated demonstration show, positively impacted student feelings in regard to the subject of chemistry, in general. As a teacher researcher, this led me to recognize the profound significance of demonstrations in the high school chemistry classroom. It was revealed that demonstrations should not be the sole method of teaching chemistry, but should be supplemented with other hands-on experiences, such as laboratory investigations. I agree with Beall when he says, "Demonstrations are only one of many teaching techniques and should not be used for their own sake." (Beall, 1996, p.641) However, demonstrations do lead to lasting memories and positive attitudes about the subject. Therefore, demonstrations should be encouraged at the high school level. Additionally, elementary students are impacted when high school students perform demonstrations for them. They learn beginning chemistry concepts while the high school students learn how to explain complex concepts in a simplified way. Both younger and older students are positively impacted. Based on my findings here, I plan to make the chemistry demonstration show an annual event.

Two important questions arose as a result of this study that I plan to examine in the future. First, what impact did student performances of the "exocharmic" demonstrations have on their own learning? At the time of this writing, students had not yet been tested following their show for the elementary students. Perhaps direct student planning and facilitation of demonstrations played a more significant role in their conceptual development and understanding than would have been possible by merely observing teacher-executed demonstrations. Another question to look into is whether or not the elementary students will truly remember the demonstrations in future years. If they do, will they enter my high school classroom with a better outlook on the subject of chemistry? Will they be better rooted in the fundamental concepts of chemistry than students who didn't witness demonstrations like these when they were in elementary school?

In closing I am going to list some of my favorite quotes from the student reflection assignment. They truly reveal the change in attitudes that occurred during my inquiry:


  • "In the beginning I really didn't understand the reason behind the demonstration of the 'chemistry' of it. But when we actually had to mix our own chemicals and make the reaction happen, it made me understand everything a lot better."

  • "The Demo-A-Day was a great and fun learning experience."

  • "At that very moment, I wanted to be a chemistry teacher."

  • "I think you should do this next year with the upcoming chemistry class. The demos were the most exciting thing we've done all year."

  • "Things like this make Chemistry fun."
