A Look at the Effectiveness of High School Chemistry Curriculum in Preparing Students for ACT

In the ever-changing world, students are challenged with cultivating the skills and knowledge needed to handle the pace and level of understanding required to excel in their future. The foundation for a student\u27s future begins in their formative years, but high school is a prime environment for nurturing the applied, critical thinking, and problem-solving skills needed to move forward into independent, adult life. Mississippi schools are ranked by an accountability score, which is used to determine fund allocation and the development of improvement plans. This score is compiled by looking at various state-tested courses, College and Career Readiness Standards (MS CCRS) scores (including the ACT), and graduation rates. Chemistry is not an accountability subject, but students who take chemistry also take the ACT in the same year. In this case, the ACT serves as a tool for accountability and a tool for predicting college readiness and success (ACT.org, 2016). Given that the skills needed to succeed in chemistry are also needed to succeed on the ACT, it seems prudent to find ways to help students understand the chemistry content while simultaneously strengthening the skills to do well on the ACT Science sub-test. To address this, a two-tiered study was conducted over five years to determine if integrating an Inquiry-Based (IBL) method, specifically Process Oriented Guided Inquiry Learning (POGIL), would benefit student chemistry success and increase scores on the ACT. The first two years looked at the effects of POGIL integration by comparing 3 assessment scores (Pre-test, Post-test, and ACT science sub-test). Years 3-5 sought to establish a difference between teaching methods by comparing the effects of POGIL integration versus non-POGIL integration The POGIL and non-POGIL classes were taught by two different teachers, and the scores were compared through the 3 same assessments (Pre-test, Post-test, and ACT Science sub-test). The research significantly impacts student ACT Science scores over a five-year period. The two-tiered study indicated that students were better prepared to be successful on the ACT science test. The change came through using critical thinking in the chemistry classroom in controlled environments and helping students build capacity with those skills

Rethinking Metacognitive Intervention: A Scaffolded Exam Wrapper Strategy

Students lack the behaviors and strategies that support success in postsecondary environments, which has led one-third of all college students to enroll in remedial courses (Bowen, Chingos, & McPherson, 2009). One particular executive function that low-achieving students are often without is metacognition, or thinking about thinking. Traditional models of education in the United States do not teach students how to analyze their performance even though metacognition is linked to improved academic performance (Young & Fry, 2008). This work presents a scaffolded metacognitive strategy to help low-achieving students improve their metacognitive skillfulness and examination performance

Addressing the problem of student engagement in the classroom

The problem of student engagement is one that is faced by teachers everywhere. While multiple strategies exist for combating this issue, project-based learning and inquiry-based learning are two that stand out in the multitude of research. Additionally, these strategies are ideal in the science classroom as they align very well with the Next Generation Science Standards that are used in Michigan, including rural Southwest Michigan school, Eau Claire High School. This project explores these instructional strategies and their various benefits which include improved critical thinking, improved social skills, and improved questioning skills

Influence of process oriented guided inquiry learning (POGIL) on Science Foundation students’ achievements in stoichiometry problems at the University of Namibia

The study investigated the influence of Process Oriented Guided Inquiry Learning Approach (POGIL) on Science Foundation students’ achievements in stoichiometry versus traditional lecture centered pedagogy. Two intact science foundation class groups at the University of Namibia were used as a case study. A quasi-experimental non-randomized pre and posttests control group design was used to investigate the achievement in stoichiometry. Data on student achievements were collected and analyzed using descriptive statistics and Analysis of Covariance (ANCOVA). The ANCOVA results showed that there was a significant statistical difference in achievements when comparing the adjusted mean score (54.5%) obtained by the control group and the adjusted mean score (60.5%) obtained by students in the POGIL group; (F (1,75) = 17.990, p < 0.05). The POGIL group also showed the highest average improvement (65%) on questions related to reaction stoichiometry and limiting reagents, whereas the control group recorded improvements of about 53% in the same section. The results from the analysis of student’s test solutions revealed that the POGIL group students were able to give concrete reasons for their answers that they had obtained through numerical calculations or multiple choices and demonstrated enhanced understanding of linking various stoichiometry concepts.Science and Technology EducationM.

Problem Solving Thinking Skills: Effectiveness of Problem-Solving Model in Teaching Chemistry College Students

Problem-solving is considered one of the thinking skills that must be possessed in 21st-century education because problem-solving skills are needed to solve all problems that arise. This study aims to describe problem-solving thinking skills as a manifestation of the effectiveness of problem-solving models in college student chemistry learning. The research method uses descriptive research with a quantitative approach. The design used is One Group Pretest-Posttest Design.  This research was conducted in the chemistry department Universitas Negeri Surabaya with the subjects of 31 college students who programmed basic chemistry courses on chemical thermodynamics. Measurement of problem-solving thinking skills using a paper-pen test (pretest and posttest) in the form of an essay. This research findings show that: (1) Each indicator of problem-solving thinking skills of trained college students gets percentage, namely understanding problems 76.08%, planning problem solving 80.65%, implementing problem-solving 85.49%, drawing conclusions 78.50%, and evaluating problem-solving results 68.22%; and (2) N-gain scores for each indicator of problem-solving thinking skills obtained have medium and high criteria. Based on the research results, the problem-solving model has been effective in improving college students' problem-solving thinking skills

Exploring learners’ proficiency in stoichiometry and attitudes towards science through Process Oriented Guided Inquiry Learning (POGIL) intervention

Stoichiometry is one of the difficult topics in the senior secondary school chemistry curriculum. It is usually taught through the traditional lecture method of presentation that is non-engaging for learners. Consequently, there is poor understanding, achievement, and negative perceptions of stoichiometry and chemistry in general. The goal of this study was to explore learners’ evolving proficiency in stoichiometry and attitudes towards science as a result of their participation in Process Oriented Guided Inquiry Learning (POGIL) activities. That is, POGIL which incorporates guided-inquiry and collaborative learning was introduced as an intervention strategy in learning stoichiometry. This was assessed by examining learners’ experiences with learning stoichiometry before and after the POGIL intervention. The study further investigated possible contributing factors to learners’ evolving proficiency in stoichiometry and attitudes towards science. This study employed the socio-cultural learning theory as proposed by Vygotsky (1978). The role of socio-cultural features such as ‘social interaction’, ‘cultural tools’, ‘self-regulation’ and ‘zone of proximal development’ (ZPD) were explored with regards to learners’ stoichiometry proficiency and attitudes towards science progression as they participated in POGIL activities. The work of Kilpatrick, Swafford and Findell (2001) on proficiency and Fraser (1981) on attitudes towards science were used as analytical lenses to understand learners’ proficiency in stoichiometry and attitudes towards science, respectively. This study was underpinned by the pragmatic research paradigm. Thus, a Quant + Qual concurrent mixed-methods approach which involves generating, analysing, and integrating both qualitative and quantitative data to provide answers to research questions was adopted. It was an intervention study carried out in two senior secondary schools in the Ilorin metropolis of Kwara State, Nigeria. A sample of 53 senior secondary school year two learners participated. Questionnaires and journal entries were completed by the 53 learners, while seven learners were interviewed. Data were collected using both qualitative and quantitative data generating tools including pre-and post-tests. The stoichiometry learning questionnaire (SLQ), test of science related attitude (TOSRA) questionnaire, and stoichiometry achievement tool (SAT) were used to generate quantitative data while the SLQ, semi-structured interviews, and journal entries were the qualitative data tools. Data were generated in three phases. Phase one was baseline data through SLQ, TOSRA and SAT pre-tests. The second phase was the intervention phase where the POGIL approach was implemented in the classrooms and learners were engaged in journal entries. Post-intervention was the last phase where TOSRA and SAT post-tests were administered and semi-structured interviews were conducted with participants. Thus, data were analysed quantitatively and qualitatively. Before the POGIL intervention, the findings of this study revealed that most of the learners perceived stoichiometry as difficult because of the instructional characteristics, the nature of stoichiometry concepts, and learners’ attributes. After the POGIL intervention, however, learners showed increased proficiency in stoichiometry and attitudes towards science. Findings also indicate that learners’ proficiency in stoichiometry and attitude towards science were associated with the facilitators or learning environment features, the nature of instructional characteristics, learners’ perceptions of stoichiometry or science, and the extent to which learners could comprehend or master science concepts. Notably, these features are intertwined and cohere with the socio-cultural theory and POGIL principles. This study offered insights into how proficiency in stoichiometry and attitudes towards science may develop among senior secondary school learners in Nigeria. The findings point to POGIL as an example of an instructional approach that provides enabling characteristics and useful information for planning instructional activities for the development and nurturing of proficiency and attitudes towards science. The results suggest that the POGIL strategy could alleviate some of the factors perceived as contributors to difficulty in learning stoichiometry. As such, the study makes contributions to the field of science education in Nigeria particularly regarding how both the tenets of the socio-cultural framework (social interaction, cultural tools, self-regulation, and ZPD) and POGIL (guided-inquiry and collaborative learning) could be aligned to facilitate the development of proficiency and attitudes towards science. The study, therefore, recommends that POGIL should be used as an inquiry-based approach in science classrooms to promote the development of learners’ proficiency and attitudes towards science. The study could also be utilised as a resource to guide or set a base for further investigation into the implementation of POGIL in other areas of chemistry or science as well as creating professional development spaces that promote community of practice among science teachers as observed in this study

An assessment on the effect of collaborative groups on students’ problem-solving strategies and abilities

This paper reports the use of tools to probe the effectiveness of using small-group interaction to improve problem solving. We find that most students&apos; problem-solving strategies and abilities can be improved by working in short-term, collaborative groups without any other intervention. This is true even for students who have stabilized on a problem-solving strategy and who have stabilized at a problem-solving ability level. Furthermore, we find that even though most students improve by a factor of about 10% in student ability, there are two exceptions: Female students who are classified as pre-formal on a test of logical thinking improve by almost 20% when paired with concrete students; however if two students at the concrete level are paired together no improvement is seen. It has been said that problem solving is the ultimate goal of education (1), and certainly this is true in any chemistry course (2). To be sure, most instructors value this skill and try to instill the ability to solve problems in their students. However, the term &quot;problem solving&quot; means different things to different audiences, from algorithmic problems to complex, open-ended problems that do not have one particular solution. A number of attempts have been made to define problem solving, including &quot;any goal-directed sequence of cognitive operations&quot; (3), and many now agree with the general definition: &quot;what you do when you don&apos;t know what to do&quot; (4). Problem solving can be closely allied to critical thinking (5), that other goal of most science courses, in that it involves the application of knowledge to unfamiliar situations. Problem solving also requires the solver to analyze the situation and make decisions about how to proceed, which critical thinking helps. A number of information processing models for problem solving have been developed (6-8) and attempts made to develop uniform theories of problem solving (9). However, many of these studies involve knowledge-lean, closed problems (2) that do not require any specific content knowledge to solve, and that have a specific path to the answer. The truth is that many types of problems exist and there is not one model that will be effective for all categories (10). For example, in teaching science we are ultimately concerned with knowledge-rich problems requiring scientific content knowledge. Studies on problem solving in chemistry have typically revolved around development of strategies derived from research on closed-ended problems, usually pinpointing areas of difficulty that students encounter in specific subject types, such as stoichiometry or equilibrium. A number of studies where students are given strategies or heuristics allowing them resolve word problems in order to produce a numerical answer by application of an algorithm Open-ended problem solving that requires students to use data to make inferences, or to use critical thinking skills, is much more difficult to incorporate into introductory (and even higher level) courses; it is even more difficult to assess, particularly when large numbers of students are involved. Traditional assessment methods, such as examinations and quizzes-including both short answer and multiple choice-give very little insight into the problem-solving process itself. If a student does not have a successful problem-solving strategy, these methods may not allow either the student or the instructor to see where the difficulty lies, or to find ways to improve. While other investigation methods such as think-aloud protocols and videotaped problem-solving sessions (14) give a more nuanced picture of the problem-solving process (15-17), these techniques are time consuming, expensive, and require specific expertise to analyze. These methods are certainly not applicable for the formative assessment of large numbers of students, and while they give a snapshot of a student&apos;s problem-solving ability at the time of observation, it is even more difficult to monitor students&apos; development of problem-solving expertise over an extended period. The upshot of all this previous research is that while we know a great deal about the problem-solving process in an abstract environment, we do not in fact have much insight into how students solve many types of scientific problems. Since we lack this information about how students approach problems and how students achieve competence, it is not easy to address the difficulties that students encounter as they develop problemsolving abilities. Indeed, while instructors value problem-solving skills highly, it is often the case that the only explicit instruction that many students are exposed to is the modeling of the skill as the instructor solves problems for students. So we have a situation where a valued skill is often not fully developed in students, even though we implicitly expect that they will become competent problem solvers by the end of the course. The most common assessments give no real insight into student strategies for problem solving, and therefore there is little feedback the instructor can give in terms of how to improve. The traditional assessments also tend to measure and reward algorithmic problem-solving skills rather than critical thinking and application of knowledge to new situations. It seems clear that if we are serious about wanting to incorporate meaningful problem solving into our courses, then we must go beyond the traditional assessments and design systems that allow us t

Guided inquiry-based learning in secondary-school chemistry classes: a case study

Guided inquiry-based learning has been shown to be a promising method for science education; however, despite its advantages it is rarely used in chemistry teaching in Hungary. One of the reasons for this is the lack of tried-and-tested inquiry-based teaching materials with detailed guides that teachers can readily use in their classrooms. As part of a four-year research project, new teaching materials were designed to foster scientific reasoning and scientific process skills in chemistry education in Hungary. From these materials, in this study, a guided inquiry-based chemistry task was tested with 9th-grade students ( N = 88) who had no previous experience with the method. Before the activity, the students’ mid-term grades were collected, and the Lawson Classroom Test of Scientific Reasoning (LCTSR) was administered to describe the sample. During the activity, students worked in groups ( n = 21). Data were collected through content analysis of the student worksheets, classroom observations using a rubric, and student questionnaires to explore the learning paths and identify possible obstacles. Our findings support that guided inquiry learning is suitable for students who are new to the method if appropriate scaffolding is given. The data showed the phases of the inquiry cycle in which more guidance is necessary. Formulating hypotheses, recording observations, and evaluating the hypotheses based on the evidence were found to be the most critical steps in the learning process. More than half of the groups disregarded the collected evidence and accepted their original hypotheses, despite their unproven validity, suggesting that they did not understand the true nature of the scientific inquiry. Chemistry grades and the LCTSR scores could not predict reliably the students’ success in solving the inquiry task. The results of the student questionnaire showed that the students enjoyed the inquiry session. They mostly found their work successful, but they overestimated the level of their inquiry skills in some cases
