Introduction
The National Science Education Standards (NRC, 1996) contain a chapter devoted to Standards for Professional Development for Teachers of Science, whose purpose is to "provide criteria for making judgments about the quality of the professional development opportunities that teachers of science will need in order to implement the National Science Education Standards" (p. 55). Using these standards as the criteria should give districts/schools all the tools they require for the evaluation of the professional development of their teachers.
Assessment of Teachers in Professional Development Activities
Within each of the modules on this website suggestions for evaluating teachers' learning are included. The assessments we suggest are specific to each module, but in general, fall into one of several categories:
Each section of the learning cycle procedures includes a suggestion for assessment (please see the essay on the learning cycle for more details).
In addition, the professional development provider may wish to use one or more quantitative measures within the context of a coordinated program of professional development activities. The instruments provided below are only two of the many that can be found in the education literature. References to these instruments is provided; each has met validity and reliability requirements for a sound instrument; each could be used as a pretest to gather baseline data and then as a posttest to look for change as a result of the professional development program intervention.
The Shrigley-Johnson Science Attitude Scale (Shrigley & Johnson, 1974) provides information on the science attitudes of inservice teachers using a Likert-type scale. Analysis of teachers' scores could be sorted by the gender, age, teaching experience, license area, or any choice of variable. Two dimensions of teachers' self-efficacy (outcome expectancy beliefs and personal self-efficacy beliefs) are measured by using the Science Teaching Efficacy Beliefs Instrument (STEBI) (Riggs & Enochs, 1990). If teachers score low using this measure it might mean that they believe that they cannot effectively teach science or that, even if they teach effectively, their students cannot learn science. Ascertaining teachers' beliefs helps predict their science teaching behaviors and is useful as a first step in the change process.
Evaluating the professional development experience
In this section we will give some specific suggestions that professional development providers might use to evaluate the effectiveness of the session they have conducted using one or more of the modules found on this website. The publications (*) referenced in the bibliography (only a starting place) give much more information and should probably be acquired for your personal library.
In their seminal work, Designing professional development for teachers of science and mathematics, Loucks-Horsley, Hewson, Love, and Stiles (1998) suggest several questions that professional development providers should ask themselves and proceed to elaborate on these questions and to give helpful tips in answering them.
These questions include:
Helpful tips to answering these questions include:
Guskey (2000) describes five sequential levels to be addressed when evaluating professional development. This short essay will only give brief descriptions of these levels. We encourage the reader to study Guskey's model carefully and design the local plan around this inclusive, logical framework.
Level One: Participants' Reactions
This level is the first, most common, and easiest to evaluate. Questions guide the evaluation and these questions cover several areas.
Collecting answers to these questions often requires a written evaluation form or survey completed at the end of the session. Based on your goals it might be useful to distribute such forms to participants several days after the event, thus allowing participants time for reflection on the experience and its relevance. Guskey gives several examples of forms (pp. 108 - 114) that might be used or amended to measure level one. It is important to consider how the information gathered at this level will be used. Typically, results of these evaluations are used to affect improvements in subsequent professional development sessions.
Level Two: Participants' Learning
Did the participants acquire the intended goals? This is the key question to address at this level. Remember: there may be various types of goals to be measured - cognitive, affective, psychomotor - the science professional development session should address all three of these areas. There are helpful forms (pp. 128 - 130) for gathering written feedback provided in the book. Other forms of evaluation include interviews, participants' learning logs, participants' reflective journals, pretests, and posttests. The information gathered should guide improvements in the format, content, and organization of future sessions.
Level Three: Organization Support and Change
Organizational factors at the district/school levels can "make or break" the professional development experiences. The values, beliefs, and norms of the organization (culture) need to be recognized when changes advocated in the professional development goals are pursued. Therefore, we should look at variables related to support for change. Among these variables are organization policies, resources, collegial support, the principal's support, administrators' leadership, provision of time, and recognition of success. Tools that may be useful in collecting data to measure the effect of these variables include direct observations, focus groups, questionnaires, structured interviews, and reflective journals. Results of this evaluation should inform all aspects of organizational support.
Level Four: Participants' Use of New Knowledge and Skills
Did participants put into practice their knowledge and skills acquired in the professional development program? At what level of use did the implementation occur? Are the practices observed/reported really new or different from participants' prior behaviors? Gathering data to answer these questions may involve direct observation; interviews with the participant, his/her supervisor, his/her students; focus groups; reflective journals; and, participants' portfolios. Analysis of data provides evidence on current levels of goal-attainment and can help restructure future activities.
Level Five: Student Learning Outcomes
The standards movement and the focus on accountability have put emphasis on students' learning outcomes as a consequence of teachers' professional development experiences. Like teachers' learning outcomes, three domains (cognitive, affective, and psychomotor) should be addressed when measuring students' learning outcomes. Standardized performance assessments, teacher-developed classroom assessments students' portfolios, questionnaires, and school records are vehicles for data collection. Qualitative measures are useful in measuring affective learning outcomes. Guskey cautions that multiple measures of student learning be used in professional development evaluations.
Guskey closes his book with suggestions for presenting evaluation results, including a helpful framework on p. 259.
