Heller, J.I., Daehler, K.R., Wong, N., Shinohara, M., & Maritrix, L.W. (2012). Differential effects of three professional development models on teacher knowledge and student achievement in elementary science. Journal of Research in Science Teaching, 49 (3): 333-362.
- Study’s sample
- 6 states
 - 270 elementary teachers
 - 7000 students
 - Same science content components
 
 - Teacher intervention types:
- Teaching Cases
- Design Goals
- Examine students’ science ideas as they pertained to key concepts in electric circuits, critically analyze trade-offs among instructional options,
 - See content as central and intertwined with pedagogy
 - Focus on the specific content and curricula being taught.
 
 - PD Activities
- Analyzing the student work presented in a case in terms of correct and incorrect ideas
 - Identifying the logic behind common incorrect science ideas
 - Analyzing the teacher’s instructional choices
 - Weighing the tradeoffs of instructional choices in terms of the benefits and limitations of a model, metaphor, definition, or representation used by the teacher in the case
 - Considering the implications for teaching their own students
 - Reflecting on the process of using cases as a tool for learning.
 
 
 - Design Goals
 - Looking at Student Work
- Design Goals
- Examine students’ science ideas as they pertained to key concepts in electric circuits,
 - Recognize evidence of incorrect mental models, correct understandings, and proficiency,
 - Analyze tasks to identify characteristics that support formative assessment, and make instructional choices grounded in evidence of student thinking.
 
 - PD Activities
- Identified science concepts that were central to a student task
 - Completed the task and analyzed its cognitive demands
 - Identified assessment criteria or constructed an assessment rubric for the task
 - Analyzed the student work in terms of correct and incorrect ideas, as well as common mental models
 - Considered the implications for teaching and learning
 - Described the merits and limitations of the task
 - Reflected on the process of looking at student work.
 
 
 - Design Goals
 - Metacognitive Analysis
- Design Goals
- Identify concepts that teachers found challenging to learn related to electric circuits,
 - Examine the logic behind common incorrect ideas pertaining to the topic,
 - Reflect on their own and others’ processes for learning science
 - Analyze the roles of hands-on investigations, discourse, and inquiry in science learning.
 
 - PD Activities
- Science ideas they learned during the science investigation
 - Concepts that were particularly tricky or surprising
 - The logic behind an incorrect science idea that they had
 - The implications for what students should learn and how the science content should be taught.
 
 
 - Design Goals
 - + “business as usual” control group
- Regular PD sessions
 
 
 - Teaching Cases
 - All 3 showed significant improvement in learning outcomes
- But better focus on student’s ways of learning rather than teacher’s
- “Findings suggest investing in professional development that integrates content learning with analysis of student learning and teaching rather than advanced content or teacher metacognition alone.” (Heller, Daehler, Wong, Shinohara, & Maritrix, 2012, p1)
 
 
 - But better focus on student’s ways of learning rather than teacher’s
 - Research Questions & Results
- 1. What effects do the teacher courses have on teacher science content test scores?
- All 3 methods showed content test score gains, little difference amongst them
 
 - 2. What effects do the teacher courses have on teacher written justifications?
- All 3 methods showed content test score gains, little difference amongst them
 
 - 3. What effects do the teacher courses have on student science content test scores?
- All 3 methods showed content test score gains, little difference amongst them
 
 - 4. What effects do the teacher courses have on student written justifications?
- Only “Looking at Student Work” course significantly improved scores
 - “Teaching Cases” showed some results in the second year
 - “Metacognitive Analysis” did not show improvements compared to control group
 
 - 5. What effects do the teacher courses have on English language learner science content test scores?
- All 3 methods showed content test score gains, little difference amongst them
 
 - 6. What effects do the teacher courses have on English language learner written justifications?
- No improvements
 
 
 - 1. What effects do the teacher courses have on teacher science content test scores?
 - Requirement
- Only the “Looking at Student Work” group were teaching the content at the same time as the PD was being delivered – could this have affected/biased the results!?
 
 
- Conclusion
- PD was delivered not only by the developers, but by trained facilitators
- “The positive outcomes indicate that the train-the-trainers model has the potential for broad dissemination and impact at a relatively low cost. While there is a considerable body of research on professional development for teachers, there is almost no research on preparation of facilitators of professional development.” (Heller, Daehler, Wong, Shinohara, & Maritrix, 2012, p25)
 
 
 - PD was delivered not only by the developers, but by trained facilitators

- Study to evaluate “whether and how professional development can help teachers design sequences of instruction that lead to improved science learning.” (Penuel, Gallagher, & Moorthy, 2011, p996)
 - Measured across 2 dimensions:
- The extent to which the programs guided teachers’ selection of curriculum materials
 - Whether or not teachers received explicit instruction in models of teaching associated with particular methods for designing instruction.
 
 - Results
- Positive student learning outcomes where “teachers received explicit instruction in models of teaching” (Penuel, Gallagher, & Moorthy, 2011, p996)
 - “we hypothesized that for teachers to use instructional materials well in the classroom, they must receive explicit instruction in the models of teaching that underlay those materials.” (Penuel, Gallagher, & Moorthy, 2011, p999)
 
 - “Professional development should aim to guide teachers’ design of instruction and uses of curriculum materials (M. W. Brown & Edelson, 2003; Davis & Varma, 2008)” (Penuel, Gallagher, & Moorthy, 2011, p997)
- “emphasis in recent years has been placed on preparing teachers to follow, rather than create or adapt, curriculum materials and programs (Institute of Education Sciences, 2009)” (Penuel, Gallagher, & Moorthy, 2011, p997)
 - Assumptions by policy makers et al. that teachers do not possess significant PCK, therefore want teachers simply follow curricula designed be ‘experts’
 - “Teachers inevitably do adapt curricula and programs to fit their classroom contexts (Squire, MaKinster, Barnett, Luehmann, & Barab, 2003)” (Penuel, Gallagher, & Moorthy, 2011, p997)
 
 

- Research questions
- Do students learn more Earth systems science when professional development guides them to select curriculum materials that are focused on learning goals when designing units of instruction?
 - Do students learn more Earth systems science when professional development for their teachers provides them with explicit instruction in models of teaching?
 - To what extent does variation in teachers’ enactment of models of teaching, whether these models are taught explicitly or not to teachers, account for differences in student learning?
 
 - Roots of the problem – curriculum lacking the How
- “past two decades have been focused on the development of curriculum materials aligned to standards (National Research Council, 2006).” (Penuel, Gallagher, & Moorthy, 2011, p998)
 - “few provide sufficient opportunities for students to investigate phenomena directly in a way that gives students an experience of doing science (Kesidou & Roseman, 2002)” (Penuel, Gallagher, & Moorthy, 2011, p998)
 
 - Teachers will adapt – so design for that
- “importance of anticipating teachers’ uses of curriculum in planning professional development.” (Penuel, Gallagher, & Moorthy, 2011, p999)
 - “organize professional development for productive adaptations.” (Penuel, Gallagher, & Moorthy, 2011, p1000)
 
 - Teach the teaching models prescribed within the curriculum
- “provide teachers with explicit guidance or instruction in the models of teaching specified within materials” (Penuel, Gallagher, & Moorthy, 2011, p1000)
 - not enough to put a side note within the written material – must model, enact it, and engage with it
 
 - Understanding by Design
- “UbD is a framework for designing curricular units of instruction that centers on the big ideas, essential questions, and authentic performances (Wiggins & McTighe, 1998).” (Penuel, Gallagher, & Moorthy, 2011, p1002)
 - Similar methodologies
- Project-based learning (Blumenfeld et al., 1991; Krajcik & Blumenfeld, 2006; Krajcik & Czerniak, 2007; Krajcik et al., 2008)
 - 5E (Engage–Explore–Explain–Elaborate– Evaluate) instructional model (Bybee, 1997, 2004; Bybee et al., 2006)
 
 
 - Study Methodology
- 3 PD interventions + control group (no PD intervention)
 - Dimensions of differentiation
- Teachers received professional development in which they were guided to select materials focused on learning goals and that incorporated inquiry-oriented pedagogy
 - Teachers received professional development that provided them with explicit instruction in models of teaching.
 
 - Conditions
- 1) Earth Sciences by Design
- Prepares teachers to apply the principles of UbD
 - No guidance on choice of materials
 
 - 2) Investigating Earth Sciences
- No explicit instruction in the models of teaching
 - Do not use external materials, only the ones in the website
 
 - 3) Hybrid
- Explicit instructions in the models of teaching & Practice in the design of curricula
 - Content should be at least 50% from the website – guidance provided in selecting external material
 
 - 4) Control
- Simply given the curriculum – did not participate in any PD, even though they could
 
 
 - 1) Earth Sciences by Design
 
 - Findings
- “what is particularly important is that teachers develop the capacity to design sequences of instruction by learning a set of pedagogical principles that can guide their selection or adaptation of materials.” (Penuel, Gallagher, & Moorthy, 2011, p1020)
 - “policy considers neither teachers nor curricula in and of themselves as agents of change.” (Penuel, Gallagher, & Moorthy, 2011, p1021)
 
 
Carlson, J. & Gess-Newsome, J. (April 2014). PCK in biology teachers resulting from professional development and educative curriculum materials. Paper presented at 2014 AERA Annual International Conference, Philadelphia, PA.
- PCK Indicators
- Describe the big ideas in a given content area and the relationship among those ideas.
 - Articulate what they intend students to learn about those ideas.
 - Understand why it is important for students to understand these ideas.
 - Recognize the prerequisite knowledge that they as teachers must have to teach a concept.
 - Understand the difficulties associated with teaching a particular concept.
 - Draw upon a repertoire of ways to ascertain students’ understanding or confusion.
 - Use knowledge about students’ thinking and context to influence instructional decisions.
 - Present multiple representations for the teaching of a concept.
 - Provide a rationale for the selection of teaching strategies and procedures.
 
 - Educative Curriculum Materials
- Analyzing Instructional Materials (AIM) for Selection
 
 - Key characteristics of transformative PD
- Create a high level of cognitive dissonance to disturb the equilibrium between teachers’ existing beliefs and practices and their experience with subject matter, students’ learning, and teaching;
 - Provide time, contexts, and support for teachers to think and revise their thinking;
 - Connect professional development experiences to teachers’ students and contexts; Provide a way for teachers to develop practices that are consistent with their new understandings
 - Provide continuing help in the cycle of issue identification, new understanding, changing practice, and recycling.
 
 - Hypothesis
- Increase teacher’s academic knowledge
 - Improve their PCK
 - Change their practice to be more inquiry-oriented.
 
 - Challenges for the teachers in changing practice
- Students though, are not used to ‘thinking about how they think, think about what they know’
 - Time
 - Availability of lab materials
 - Personal beliefs on what is important to teach and what students could learn
 - Conflict in the goals of instruction (own or district’s)
 
 - Conclusion
- It worked – using PD to discuss how to implement a curriculum worked.
 - Expensive – time, money, and expertise required
 - Teachers lacked depth and breadth of teaching strategies, or what is effective teaching
 - Feel unsure or do not know what do once they uncovered students’ thinking
 - Few teachers had a conceptual grasp of Biology as a whole, only silos of content
