Transitioning to Guided Inquiry Labs in Advanced Chemistry Using Effective Mini scale Labs as an Effective Scaffolding Methodology Program Presented By Mark Langella
WB STANYS Spring Conference, April 21st, 2018
This program is designed as a guide for Chemistry Instructors to use in developing ideas to adjust the
labs they are presently using to become more Inquiry Based with techniques, questioning methodology,
and by sheer design change.
Inquiry has been advocated as an effective pedagogical strategy for promoting deep conceptual
understanding and more sophisticated scientific thinking by numerous bodies associated with chemistry
(and science) education. To allow inquiry to achieve these goals, the teacher must manage the amount
of cognitive load experienced by students while they engage in inquiry activities.
One of the objectives of this program is designed to help teachers and their students develop the notion
of framing (a form of scaffolding) and by presenting a model designed to help teachers more effectively
frame inquiry activities. Providing students with such a carefully developed background can better
orient them to the purpose of the inquiry activity, put boundaries on the problem space they will be
exploring, and reduce the cognitive load as they engage in the activity, all of which should improve the
inquiry learning experience. The program will help teachers lay the proper foundation and slowly build
up to more complex inquiry experiences.
This program addresses the importance of a minor change of approach necessary to transition to the
development of guided inquiry labs using the concepts of “ Green Chemistry” as the main reason of not
using traditional equipment to perform some of the experiments typically performed in a general
chemistry class. Examples of change is not using typical Burets, Pipets, Buret Stands, and Pipet Pumps as
tools for measuring volume .Minimize flames with 30 students in a class by using alternative heating
sources. Minimize Waste and stick to "Green Chemistry" methodology by reducing quantities to perform
and get the same results. By adjusting the methodology more lab time can be used to develop the more
time consuming Guided Inquiry Based Labs.
1. Methodology Change
a. Methodology change is designed to both minimize the amount of material consumed and the time
involved in the laboratory. Most of these experiments consume no more than 15 milliliters of reagent
per trial and the maximum time required for any given trial is no more than ten minutes allowing several
trials in a single class period.
2. Developing mini-scale kits
a. Teachers are trained on how to develop cost effective mini scale kits which will reduce cost and
storage issues.
b. Bulky Apparatus such as Burets, eudiometers, large pipets are substituted with plastic analytical
devices which are more cost effective.
3. Guided Inquiry Experiments Examples are shared.

WB STANYS Spring Conference, April 21st, 2018
a. In this course, we will explore, develop and apply Project -Based Learning (PBL) as an instructional
strategy in secondary science education. In doing so, we will pursue two lines of inquiry. In the first, we
will seek to better understand the value of Project -Based Learning and critically analyze the ways in
which it can be applied to science education in the secondary school context.
b. This course is designed to enable teachers to introduce inquiry into their curriculum through framing,
a form of scaffolding. Utilizing this approach, teachers will provide students with sufficient background
and better orient them to the purpose of each PBL inquiry - based experiment. The introduction of
theory and experimental techniques in such framing activities will help to define the problem space
students will explore with clear boundaries and reduce their cognitive load as they engage in the PBL
activity. The course will help teachers establish the proper foundation for complex PBL inquiry labs
through a progression of simpler experiments, thus improving the overall learning experience. The
course will demonstrate how the teacher must manage the cognitive load experienced by students
while they engage in PBL inquiry activities to achieve the maximum benefit from inquiry-based learning,
Here is a menu of experiments which will be discussed.

This methodology course surveys the basic structure and content nec-essary for teaching an Advanced Placement Chemistry course. Chem-istry topics such as equilibrium, kinetics, and “how to” problem solv-ing are presented. Class size, student selection, textbooks and labs are also addressed. Special attention is paid to teaching strategies, the AP exam and its grading. Some lab experiments suitable for AP classes are incorporated into the course. Participants receive examples of past AP exams, appropriate tests, worksheets and lab experiments.
This institute will provide an opportunity for high school AP Chemis-try teachers to observe significant teaching demonstrations, perform experimental procedures using computer interfaced equipment, and to review with presenters a variety of topics covered in AP Chemis-try. Teachers will have the opportunity to discuss the methodology of converting typical cookbook labs into guided inquiry labs.
Participants will have the opportunity to perform several lab exercises that align with the College Board redesign. Best practices will be dis-cussed. For each of the labs AP published related Labs will be provid-ed and reviewed. Information about the requirements for the AP Chemistry Course Audit will be shared.
Please note that this course is a methodology class for novice teachers ( less than six years teaching New AP Chemistry Curriculum) . Con-tent for teaching will be provided for study in the evening.

This is not your typical teacher training seminar. Why not? We’re not going to just talk, we’re going to see and do things that will be immediately useful in your classroom. We’re going to create and do experiments that you can use with or without modification. We’re going to see proven, effective methods of helping students understand difficult content You will get a gigabyte of files that can be used this fall in your classes. Techniques for Regents, hon-ors, and conceptual physics are consistent with approaches to AP Physics 1. We will discuss and model ideas for lower-level classes that will produce success there… and then can inspire those stu-dents to show up next year in your AP course. In this summer institute, we will discuss in detail the content and structure of the AP Physics 1 exams. More importantly, we will talk about how to teach students the physics skills that will be tested on the AP exams, and which are useful at all levels of phys-ics. We’ll be sharing teaching ideas within the group, especially in-cluding creative laboratory activities. I encourage attendance from those who are focused on improving their Regents, honors, or conceptual physics courses, as well as from those who are establishing or enriching an AP Physics program.
You will get an extensive set of materials intended for each of those courses in addition to materials for AP Physics 1. The over-arching goal of the week will be to communicate and share physics teaching ideas that, while focused on AP Physics 1, can be applied to any level of physics, including Regents / conceptual physics.
In particular, we will discuss:· Quantitative use of demonstra-
tions… whenever students can be asked to predict the result of a
demonstration, that demonstration has served a purpose beyond
simply attention-grabbing.· Laboratory activities… we will per-
form two or three of these. We will discuss how to create activities
that are not only pedagogically valuable, but which also directly
prepare the students for the types of exam questions they will
face.· In- and out-of-class assignments and activities that bring
students beyond focusing on an abstract answer. We’ll talk about
specific ideas that will help get students writing, communicating,
and experimenting.
